What are your thoughts on SN9 sticking the landing this time?

SN8 burned "engine rich" due to the CH4 header tank not providing enough pressure during the flip maneuver to maintain proper fuel flow.  The supposed interim fix is to introduce a helium charged COPV to increase tank pressure, but the long term fix ideally should be further refinement of the Raptor combustion cycle to drive appropriate exhaust levels from the respective preburners into their source tanks.

I think they're going to end up landing it this time, but I'm not really going to consider it a victory, since the craft needs to be able to perform at least 2 landings (one on Mars outbound, and one back on Earth at the return) before it can receive a helium refill.  No helium on Mars to speak of.  The goal is to be able to operate it by refueling everything it needs on Mars.

I'm sure they'll get there, I think it's already a far more capable design than the DC-X.

That's a pretty weird standard.  There are a ton of things which this craft is not capable of that would be necessary for a round trip to Mars.  SN9 isn't intended to have everything figured out to make a round trip, rather it is a small part of that design process.

The victory in my opinion is not in having a system fully developed but in continuous iterative development and improvement.

If SN9 sticks the landing I'll call it a win for sure.

They're introducing a dependency for craft operation that isn't present in its intended operational environment.  And a huge part of the design of Starship hinged upon autogeneous pressurization and the fully staged closed combustion cycle.

They've got a significant hiccup in that, that needs resolving, before any missions more demanding than Earth-to-Earth can happen.

The failure in fuel pressurization is rather damaging to their aspirations to sell a Human Landing System for Moon operations to NASA's Artemis program.

There is some question as to weather they'll finish building 11-14.  Musk said on Twitter that 15 has some design changes brought about by what they learned so far that might make 11-14 not worth finishing.

That's what fast iteration will do.

Looking on wikipedia, yeah I know it's wikipedia, and comparing the Raptor to the RS-25 on the SLS

Almost the same max thrust (R 500,000lb vs  RS-25 512,300lbs)
Raptor is smaller
Raptor is less than half the weight
Raptor has a far higher thrust to weight ratio (200.1 vs 73.1) Like WOW at the difference
Raptor uses liquid methane vs liquid H (both use liquid O as the oxidizer)
Raptor can be relite in flight multiple times

Only real advantage I see RS-25 has over Raptor is that it's a proven design (having been used on the Shuttle) while Raptor is still technically in development. Which begs the question. Why the heck is it taking so long to get SLS flying???

By the time NASA gets back to the moon SpaceX will be on Mars running at Warp 5.

FTFY

It is my opinion that NASA will never get back to the moon. Their mission budget will be slashed during the Harris/Biden administration and their focus will likely be redirected back toward muslim outreach and social justice issues.
As for SpaceX and friends, I would be surprised if the regulatory burden isn't magnified beyond financial feasibility and they take their toys to another country.
We just can't afford to be sending all that money up in smoke going into space when there are so many social justice programs here that need the money.

Pretty much this, though I think the impact on SpaceX will be slower in coming.  I believe it will take a few years for Musk to realize that the USA federal government doesn't want him around anymore.
NASA should just start mothballing permanently scrapping their manned programs now.  They should just concentrate on their unmanned projects and Muslim outreach.

https://en.wikipedia.org/wiki/RS-25

If you replaced the 4 RS-25's on the SLS with 7 Raptors in a circle (similar to the New Glenn BE-4 engine config), you could truncate the first stage of SLS by a considerable amount since hydrogen requires so much damn volume compared to methane.  This winds up reducing the dry mass of the entire stack and you can possibly even get rid of the solids on the side.

Hydrogen is a *expletive deleted*it propellant to use for sea level booster operations.  Great ISP but terrible thrust, and volume to contain the necessary hydrogen results in excessive dry mass.  Methane is better but not great, RP-1 generates more thrust than either.  Sadly, hypergolics and solid rocket motors generate the best sea level thrust.

SLS with a fat array of Merlin 1-D engines running RP-1 would be even better than a Raptor conversion.

I really don't grok the love for the RS-25 out there.  The damn things need complete rebuilding from hydrogen embrittlement after every Shuttle flight.  Might as well throw them away.  And the low thrust of them mandates the need for AsplodeyBois on the side, which killed 7 people on Challenger.  SLS still hasn't learned from those lessons, other than putting the capsule on top.

It used to be that the FAA worked for pilots.  We told them what we intended to do and they made it happen.  We also used to fly around without radar or flight following or talking to anyone.  Now, every student pilot I hear on the radio is using flight following and asking permission to fly their plane.  Damn students use flight following even on a beautiful VMC day in Florida.  The idea of self-sufficiency is dying.

They need permission in the form of a waiver.  The waiver allows the rocket folks to fly their rockets.  The FAA will issue NOTAMs and such to warn pilots such as yourself not to fly in the area of rocket launches.  A rocket can break your airplane if it bumps into it.

Yup.  FAA and FCC were created out of the need for deconfliction of shared air and EM spectrum.  And like everything corrupted by those who seek power it has been turned into an instrument of control.

A lot of what they're testing is software related.  Specifically, parameters for throttle percentage, thrust vector control angles, and aero-flap angle of attack.

That's easily tweaked from SN9 to SN10, with only a few days of configuration and validation through computer modeling.

I think they need to start the maneuver to vertical earlier in their landing regime.  It'll cost a couple more seconds in fuel though, which is supposedly about 600 kilograms per second if the engine is at 100% throttle.

That and they really need those hot gas thrusters.  Control of orientation is just insufficient with cold gas and TVC only.

Frame it with the requirement for two engine half throttle landing.  Should allow time and altitude for a single engine full throttle burn to safe landing if one engine fails.

Wonder if they could use a drogue chute to slow it somewhat and give it more time to deal with issues?

Probably not.

1. It would be a big-*expletive deleted*ss parachute. Here's some people for scale. https://twitter.com/nasaspaceflight/status/1291835348209803264?lang=en
2. It would be an unpredictable dynamic load while it's trying to manuver and balance on it's engines for landing.

Imagine being a tightrope performer who has to hang onto a parachute with one hand, and still maintain their balance.


As to the crash? Not too sad. IIRC, SpaceX crashed roughly 10 Falcon 9's before they started sticking landings consistently.

The only downside was that getting the Falcon 9 to land was "gravy" on an already paying mission that was profitable without recovery and treating it like an expendable rocket.

Probably stings a little more when Starship is meant to be reusable from the get-go. I'd imagine Musk and Co. were only 50/50 on getting a landing out of this test. IIRC, he was like 30/70 for SN8.

And yeah, SN 10 watching... sitting there like...

Title: Re: SpaceX News
Post by: AJ Dual on February 02, 2021, 05:29:28 PM
Ah. I see what you're saying about a drogue.

The main issue is when you want to deploy it. During the horizontal belly-flop stage? Or right before the pivot and suicide burn? And then cut it loose? Or hang onto it?

I think terminal velocity for Starship as it falls during the belly flop maneuver is about 150mph or so? No idea if that's just for the 10km high test flights, or if that's what it's always expected to be. You'd have to factor in the complexity of the chute with it's "dead weight" that contributes nothing to the launch to see if it's worth it. I'd imagine that SpaceX engineers have considered every angle to chutes for recovery/landing, and found them wanting. 

Fly320's correct me if I'm wrong, but don't commercial airliners come in at about 150-160mph give or take altitude of the airport, weather, and the size/make of the airliner?  Granted it's an angled grazing approach, not straight down... but I don't know if Starship falling at terminal velocity is going to benefit from a chute of any size small or large.

I think they actually have enough "control" over Starship per-se. It's just that the Raptor engines have had unexpected failures so the Starship couldn't actually maneuver the way it's software was telling it to.

Ah. I see what you're saying about a drogue.

The main issue is when you want to deploy it. During the horizontal belly-flop stage? Or right before the pivot and suicide burn? And then cut it loose? Or hang onto it?

I think terminal velocity for Starship as it falls during the belly flop maneuver is about 150mph or so? No idea if that's just for the 10km high test flights, or if that's what it's always expected to be. You'd have to factor in the complexity of the chute with it's "dead weight" that contributes nothing to the launch to see if it's worth it. I'd imagine that SpaceX engineers have considered every angle to chutes for recovery/landing, and found them wanting.

How fast was Apollo moving when they deployed their drogue chute? Note, drogue not the main chutes.
I'm just wondering if it only gain them a couple of seconds to sort out the engine situation that could be the different between life and death for a lot of people.

 *sigh*

It is produces a constantly shifting force vector as it buffets in the turbulent air.
It is largely static in force produced and not variable like the fins.
It will be redundant as the body and fins are already sufficient aerobraking surfaces.
It will act as a large sail for wind causing the craft to roll and translate unpredictably.
It will consume a significant mass fraction in order to be large enough for a vessel of this size.
It will require its own complex deployment system with pyros and mortars to deploy it eating up more mass.
It will be dead weight during most of the mission not providing any ancillary ability (heat radiators in the fins).
...


And that's just what my kerbal flinging amateur rocketry nerd self can come up with.  Imagine SpaceX's list of why they chose no chutes.

So, NO PARACHUTES, capiche?

I'm just saying to help slow it down a bit to gain a couple of seconds or so of time to sort things out and not to land the thing with. Drogue parachutes are a bit different from normal parachutes

A drogue chute would have zero effect on this thing.  It's about 125 metric tons.  You could use one of those M1 Abrams parachutes that kicks a heavy vehicle out of a C130 on a runway, it wouldn't be worth having.  In fact, a chute on the nose, even if it could hold up to the stresses and contribute in a meaningful way, would probably exacerbate the problem here.

The problem is partially the speed, but it's more around the over-correction of orientation due to Thrust Vector Control controlling the maneuver rather than Reaction Control System doing it.

The current RCS on these things is pitiful.  It's cold nitrogen compressed gas.  It's not nearly  enough to spin a steel building 90 degrees in a handful of seconds, and then stop that spin once perfectly vertical.

So what they're doing instead is using the Raptors.  When you light those things while it's horizontal, you get a bunch of horizontal velocity while you try and rotate its attitude.  That has to be negated.  What we see is the rocket rotate about 120 degrees, the TVC overcompensates in the opposite direction and cancels the horizontal velocity, then tries to come back to vertical again.

The center of rotation is closer to the nose fins while it does this.  You have to compensate for the angular momentum of nearly the whole ship, plus gravity, all at once.

SpaceX has a goal of putting hot-gas thrusters on this thing.  Tiny little methane/oxygen rocket engines similar to Raptor but much lower thrust.  Still way higher thrust than cold nitrogen though.  Using those will allow the center of rotation to move lower on the vehicle, rely on TVC of the main Raptors less, and reduce complication of the landing burn calculations.  And it would also hopefully avoid the over-correction issue entirely.  You can't avoid it if you're using your main propulsion engines to rotate the whole craft 90 degrees.

One other problem they're having is maintaining proper fuel pressure.  During ascent this thing sucks fuel from the main tanks, right above the engines.  But at the landing maneuver, fuel feed is shifted to alternate smaller tanks.  One is in the nosecone and the other is nested inside the main tank (can't remember which is O2 or CH4 and it really isn't relevant to the problem).  There is less slosh during the horizontal-to-vertical maneuver if a tank is full, and these landing tanks are tiny compared to the launch tanks.  The Raptor engine is supposed to be able to autogenously pressurize these fuel tanks with a little bit of exhaust, to keep the fuel supply steady.  That's not working quite as expected, so they are augmenting that with COPV canisters filled with nitrogen or helium or something, to boost gas pressure in the landing tanks. 

Parachutes are just not the answer to this problem.  A parachute of the scale to have any impact on this vehicle would weigh more than several seconds of fuel to burn to impart more authority to the landing maneuver.

How about pop-out and retractable panels of the actual rocket skin?  Rapid deployment, stable aero characteristics, not much extra mass for the trip (just the additional deployment and retraction mechanics) since the skin is part of the ship's normal carry load. Just a little extra drag on the trip down.  Only major problem I foresee is hinging the panel since they're part of the curved surfaces of the skin.

Merely suggestive of what I'm getting at:

Don't take that literally, it's just food for thought.  We could call them drag panels (not drogue panels.)

Should I send this idea to SpaceX?

More on that FAA business
Apparently for SN8's flight back in Dec Musk flipped off the FAA and the FAA didn't take kindly to it.

Quote
Before the December test flight, SpaceX had sought a waiver from the Federal Aviation Administration that would have allowed it “to exceed the maximum public risk allowed by federal safety regulations,” the agency said in a statement Tuesday.

But after that waiver was denied, SpaceX proceeded with the flight, violating its launch license in what aerospace and industry officials said was a potentially reckless move that could have posed serious risk to the public’s safety.

As a result of the violation, the FAA directed Elon Musk’s company to investigate the incident and suspend operations that could affect public safety at its launch site in South Texas.

Ultimately, the investigation ended, the FAA approved the company’s remedies and granted it approval to attempt Tuesday’s test.

NASA has selected Space Exploration Technologies (SpaceX) of Hawthorne, California, to provide launch services for the agency’s Power and Propulsion Element (PPE) and Habitation and Logistics Outpost (HALO), the foundational elements of the Gateway. As the first long-term orbiting outpost around the Moon, the Gateway is critical to supporting sustainable astronauts missions under the agency’s Artemis program.

After integration on Earth, the PPE and HALO are targeted to launch together no earlier than May 2024 on a Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The total cost to NASA is approximately $331.8 million, including the launch service and other mission-related costs.

Fun fact about #Starship. By doing the flip around 500m vs higher up like 2,000m, the difference in delta V is ~ 500 m/s! That's a 20 tonne fuel saving, which means basically 20 tonnes MORE you can put into orbit. That's more than a F9 has ever launched, just by flipping later!

Except it's crashed every time thus far.

A single Raptor puts out 2200kN of thrust at full throttle.  That's enough thrust to provide a greater than 2:1 thrust to weight ratio of a dry Starship at 100 tons.  Granted, a dry Starship has no fuel to put through said Raptor, and the engine reportedly burns about 600kg of propellant/oxidizer per second.  The current maneuver at 500 meters needs 20 to 24 tons of fuel/ox to accomplish its goal when landing on 2 engines and performing the entire maneuver in a 20 second window.

Every ten seconds added to the burn is an additional 12 tons of fuel for 2 engines, or 6 tons for a single engine.

Starship's terminal velocity in belly flop orientation is about 100 meters/sec.  Starting the burn on a single engine at 2000 meters and initiating the orientation change more slowly on a single engine will cost 15-20 seconds of additional burn time.  As the engine gimbals to face downwards, it slows descent of the craft so that it is in air that much longer and needs that much more fuel to avoid falling out of the sky.

That single Raptor, working with 40 tons of fuel and a 100 ton Starship, has a TWR of 1.57.  It's going to cancel out 5.7 meters/sec of downward velocity, and that number is going to climb every second since the ship gets lighter from burnt fuel.  It'll take 17 seconds to cancel out vertical velocity this way, or about 10.2 tons of fuel.  That 17 seconds offers lots of opportunity to assess engine health, and possibly spool the remaining engine(s) for an alternate landing solution.

Two Raptors have a TWR of 3.54 (100 ton craft and 24 tons fuel).  Every second that two Raptors fire, they cancel out 25.4 meters/sec of downward velocity, and that number climbs every second as the ship gets lighter.  Obviously takes a lot less time to hit 0 m/s from 100 m/s this way (4 seconds, or about 5 tons of fuel).  But there's no margin for error.

Right now their whole landing maneuver is a sub-20 second burn, with flip.  Musk's big talking point on this was redundancy when it comes to human rating this thing.  When you need two engines for the TWR of the finished craft loaded with cargo, and you don't have time in your flight profile to spool the 3rd engine at some point in the landing approach, then you don't have redundancy.

I think paying the 10-20 tons of additional fuel penalty for the additional landing contingencies that a higher flip provides is worth it.

Apparently, it benefits a lot of people. The basic principle of modern capitalism is that a person or a company is successful (profitable, etc.) only when it benefits society. This means that people are willing to pay a set price for the services or goods that the company provides.
So society now considers electric cars and space companies useful.

Don't those wind turbines use grid power to heat the important bits and to keep things running when the wind dies?  That's what I read somewhere.

One of my old shipmates lives in Texas. Their power is out. Their power supplier relies heavily on wind turbines which are apparently frozen up, so much for green energy.

Yes, I am sure.  Read the article a few days ago where the OBiden administration stated they are "re-evaluating" the program.  That's typical political speak for impending cancellation.
NASA is still selecting contractors solely because of bureaucratic inertia as the program has not been officially cancelled yet.

Debris cleanup will never happen with disposable mentality to everything sent up.  The only people who have a prayer of having a valid opinion on the matter right now are SpaceX.  BO can keep its trap shut until it makes orbit and has reusable hardware capable of doing so.

About the only viable debris cleanup tech I can envision, available on today's horizon, would be a laser based satellite which tracks space debris and discovers new targets, and with the laser it vaporizes a small portion of the debris to create thrust to push the trash into Earth's atmosphere.  The trouble with that is it isn't far off from being considered a weapon.  And could even target manned or unmanned operational spacecraft, or even terrestrial targets, with devastating results.

As-is, I think what Musk is doing with Starlink is genius.  It's going to make all the GEO comms satellites obsolete when fully deployed.  They self-immolate inside of about 5 years, no need for clean up.  The rest of the stuff at 400km or lower will eventually fall into Earth's atmosphere on its own.  Even the ISS needs periodic boosts or it will fall out of the sky.

The other glorious thing about Musk's plan is it doesn't matter what detractors think.  He's paying for it himself.  People who support colonization of Mars can buy Starlink internet deliberately to support the effort.  For the most part, it's funded by Starlink, by SpaceX launch contracts, and Musk's Tesla stock.  No tax money.  So naysayer opinions just don't matter.

Exactly. That's why I'm wondering why I still see articles mentioning this on the net.
And the idea could be good in the future when this is backed up by the availability of cheap, durable material for the space elevator. (I doubt the space elevator will ever be built.) I think the time has come when private space companies will set the tone for space exploration. (Will seek profit)

Clear. You are a fan. It's not bad. (And most of this company's endeavours are well thought out) But
Otherwise, you would know that there are several dozen projects aimed at developing space tugs, foam trash catchers, and so on.
New space companies and startups (which was also SpaceX 12 years ago) are initially developing methods to clean up what they are going to launch into orbit.
Of course, at the moment the closest space debris cleaner is the reusable space tug (https://www.skyrora.com/space-tug) from Skyrora.
This does not solve the problem with the 50th 2-tonne remnants of rockets in orbit, but it is already a start.

A "laser broom" has really good promise for deorbiting debris.  BLUF: You shoot the leading surface of space debris and it ablates off creating thrust that lowers it's orbit so it finally falls into the atmosphere and burns up.

Yeah but that is a bad place to "shoot" from because of angles and atmospheric attenuation.  This is the sort of thing you put in a geostationary orbit (or farther) so you can shoot the debris and hit its prograde aspect.

We still don't have a debris cleanup program. But there are a bunch of ideas on how to send even more garbage there.

The advantages of an O'neill cylinder or other space colonies is you can put them wherever you want. Namely closer to Earth and Cislunar space so they're not cut off by significant light lag for communications, and get the fuller benefit of solar power by being closer to the sun than Mars is. Plus once it's going, you can move it anywhere under low thrust, kind of like mobile city. So if there's a good asteroid going by, you could in theory follow it and go mine it.

Other advantages, you can build them to spin and produce 1 earth G, so no issues with bone density or any other gravity related illnesses or developmental problems in children (assuming bio-tech doesn't come up with alternative answers) And you can cover them in asteroid debris to block any/all solar or cosmic radiation. And with a mass of a small asteroid, you've got almost no lift costs to send people or materials away from there to other destinations in the Solar System. Leaving a space colony would be cheaper than even lifting off from the Moon.

And further down the road, if we never develop tech to move really fast in space, just sending an entire space colony can make long distance trips to the outer solar system, or maybe even someday interstellar, do-able since people would be more willing to go if their entire community and all the comforts of home goes with them.

What is unsaid though is how you actually BUILD such a ginormous tube in space from (presumably) asteroid or Lunar materials. OTOH, we have a pretty good idea of how to dig on Mars or Luna, or use existing caves or lava tubes to hide from radiation. And in theory, the low gravity of Mars or the Moon isn't a show stopper long-term. You could build a city/base as a shallow cone to spin it and create a centrifugal force vector combined with Mars or Lunar gravity to create 1 G like on Earth. And while solar power in Mars orbit or further is not ideal, it still works. Just at less efficiency.

Of course, the correct answer is to try both planetary settlement and space colonies, and see which works best. Since we've really done neither before and it's difficult to extrapolate or simulate all the complex factors in both undertakings.

Plus once it's going, you can move it anywhere under low thrust, kind of like mobile city. So if there's a good asteroid going by, you could in theory follow it and go mine it.

Initially sounds good, but the dV you'd need to match up with a passing asteroid is ENORMOUS.

Humanity would drive itself into heat-death from expending reaction mass to chase asteroids if that were our objective (pushing an O'neil cylinder to match same vector as asteroids).

Sending robotics to slowly mine the asteroid, eject the useless bits into dust gently orbiting the mass, and use some of the asteroid (H2O, N2, Xenon, whatever) as reaction mass to propel the valuable bits to a manufacturing site, is a far better solution.  But this is thinking trans-generationally, which doesn't really pan out on high risk new technology space ventures.

Rolled it back to Pad Closeouts.  Someone in a pickup truck is out near the tank farm from looking at the video.  No one is clear on whether it is a SpaceX person investigating a problem, or someone that sneaked into the launch area.  From the camera shot, the pickup looks very similar to the one that was chased away during the launch of SN9.
Tank farm activity has stopped.  Things are uncertain about launching today at this point.

Timeline adjusted on my feed.  Last step was "Vehicle Safing"  The added a new last step "Or Not".

Still, it was the best flight yet.  Landing legs did actually deploy, but one or more may have had problems.  Musk is known to be less than satisfied with the current landing leg design.  SpaceX will get a lot of good data from this flight.

Got my first chance to really get a good look at some videos full screen

1) Looks like the legs did deploy but couldn't tell if it was all of them or not. Plus one or more may not have locked in place.

2) Looking at this video full screen it appears she may have bounced a few times upon touchdown which may or may not have damaged the legs https://twitter.com/NASASpaceflight/status/1367254064791244800
Either way the legs IMHO need to be far beefier. I know Musk is obsessed with cutting every oz, for very good reasons, but he may have to accept some weight gain in a few areas IMHO.

SpaceX has already said several times this isn't the actual landing leg design.  These legs are a "placeholder" design while they get more of the vehicle designed and tested.  No point in designing robus Mars Capable landing legs until you know if the part of the rocket they attach to is at it's final design.

Aware, just feel if they want to recover their test vehicles intact beefier legs would probably help. I'm sure they would like to at least recover the raptors.

Title: Re: SpaceX News
Post by: AZRedhawk44 on March 04, 2021, 02:32:02 PM
Correct me if my understanding is wrong. but what we have here in Starship is a LOX header tank in the nose.  After that we have a large empty space in the nose cone which will ultimately be either cargo or human habitat depending on craft version and design.  After that we have the methane tank.  Between the primary methane tank and the bottom LOX tank, we have the methane header tank.  Finally, we have the primary LOX tank and then engines and landing gear at the bottom.  The LOX header is in the nose for ballast/balance reasons, since O2 is heavier than CH4 and serves to counterbalance the mass of the engines at the rear.

So there are two header tanks, and two primary tanks.

The task of the primary tanks is to provide fuel for launch and acceleration operations in flight, and to provide fuel storage and plumbing facilities for orbital fuel transfer operations.

The task of the header tanks is to provide fuel for post-belly-flop landing maneuvers, so that the tank is full and slosh is minimized for reliable delivery to the turbopumps.

SpaceX has said before that they intend to expose the primary tanks to vacuum during routine spaceflight.  This is supposed to help insulate the header tanks so that their cryogenic payload is easier to maintain on their limited electrical budget in the vehicle.  Obviously they had neither the time nor the altitude to accomplish that here, and suffered from an artificially imposed altitude ceiling from the flight plan.  They cannot safely burn 100% of the fuel in the primary tanks without damaging the engine turbopumps, and they cannot vent the tanks in Earth atmosphere during the belly flop since there is neither time nor ecological willpower to spray methane into the atmosphere.  So these low altitude test flights and landings will all suffer from the drawback of having residual fuel in the primary tanks.

So on a real flight, an energetic explosion like this is considerably less likely because the primary tanks would be empty.

But:

One would hope that the primary tanks are not holding vacuum during reentry to Earth or Mars.  Hopefully they're sucking ambient atmosphere in to maintain neutral pressurization during reentry, or being gently pressurized by a suitable inert gas during descent.  A jarring impact like seen during yesterday's landing would result in a vacuum container crumpling much more easily than a container at one atmosphere of pressure.  And while Raptor offers autogenous pressurization of its fuel tanks via exhaust recirculating, apparently it does not offer enough spare exhaust to 100% pressurize the header tanks without assistance from nitrogen COPV's right now.  So it certainly cannot pressurize the much larger primary tanks with O2 or CH4 exhaust from the respective preburners.

According the The Angry Astronaut SN10 landed harder than desired because of another header tank issue. The engine started consuming helium out of the header tank pressure system that was installed in SN10 to help solve the low header tank pressure issue that occurred on SN8 (and maybe SN9) and thus wasn't producing the required thrust on landing. They're going for another helium less system on SN11 (11:24 in the video). And they beefed up the landing legs

Evidently just two boosters, 1051 and 1049, have each launched 10% of all currently active satellites in orbit.

Two SpaceX boosters account for over 20% of all active satellite launches (by count... not by mass).

https://www.reddit.com/r/SpaceXLounge/comments/m590hw/1051_and_1049_have_each_launched_10_of_all_active/

Obviously the tiny size and packing density of Starlink missions makes that possible.  But still... 9 launches each on those two boosters.  And they're going to use them until they break.  I expect to see an examination/servicing period after the 10th flight of each one, then roll them back into rotation.

I saw this pic on /r/SpaceXMasterRace:

(https://i.redd.it/8zrtvq3kd7n61.png)

1050 completed its primary mission successfully.  It's being mocked for successfully diverting itself away from its designated landing zone out to sea safely, and touching down softly despite its hydraulic grid fins malfunctioning and locking up during descent.

One-and-done rockets are history.

In other news, Blue Origin actually admitted recently that they won't have a New Glenn launch article until Q4 of 2022.  Which, everyone knows, really means H1 of 2023 if they're lucky.

They're also constantly shifting their deliverable date of BE-4 engines that they are selling to ULA for ULA's new Vulcan rocket, to the right.  What was supposed to be Q3 of 2020 (and 2019, and 2018, before that) is now summer of 2021.  ULA intends to try to fly a Vulcan by Q4 of 2021.  They have a ground support fitment test article out at the Cape right now.

Vulcan is supposed to be configured with two BE-4 engines on its first stage and a variable number of solid rocket motors much like its predecessor the Atlas V.  Aerojet Rocketdyne lost in competitive bidding between Blue Origin and AR, when submitting engine designs for ULA's new generation rocket.  Since then, BO's delivery schedule has slid to the right by years.  Lockheed-Martin is looking at acquiring AR.  AR was bidding a kerosene based engine called the AR-1 that has since been shelved.  The AR-1 was designed specifically to replace the Atlas V RD-180 engine which is actually provided by Russia's Roskosmos.  The RD-180 puts out about 4 meganewtons.  Two AR-1 engines put out about 4.4 meganewtons.  Two BE-4 engines put out about 4.8 meganewtons.

If LockMart acquires AR, and BO takes longer to deliver on the BE-4 deliverables, watch for pressure to mount on ULA to dramatically reconfigure Vulcan (probably a complete ditch of the vehicle) and focus on the AR-1 as a first stage engine solution.  Or use AR-1 as a basis of a new vehicle that focuses on reusability, since ULA has nothing like that and their noises regarding SMART reuse are a joke.

https://www.youtube.com/watch?v=xN-9dgJm59M

This is an interesting angle and worthy of discussion, but I just could not digest AA's format for this discussion.  Constantly breaking train of thought to thank whatever patron throws a buck into the chatroom is no way to have a content driven presentation, especially when you then have to also add praise for each region of the country/world that each donor is from.

Evidently the mass fractions are so close, and the efficiency of Raptor so high, that this scope of reusability is just not possible with any other chemical rocket engine.  Merlin, BE-4, RS-25, F1, whatever.  Can't do it without full flow staged combustion.  Which has never been done before Raptor.

What we have going on here is on par with the end of the turboprop and the rise of the jet engine, but also at the same time the peak of chemical rocket propulsion.  There is just no getting significantly better, without eliminating chemical reaction mass (i.e. that giant container of O2) in favor of some other means of energetic acceleration to enjoy the benefits of Newtonian physics.

Yeah. Of course it's "possible".

More like the "Challenge of controlled flight with an autonomous vehicle with umpteen minutes of light-lag, in an incredibly thin atmosphere."

Flying on Mars will probably always be second fiddle to rovers, aside from small side missions to look at inaccessible places like cliff sides or something. Due to the thin atmosphere and high RPM's needed it'll drain even the best battery tech fast, and create short flight with a long recharge time.

I suspect that NAA is really thinking about this with an eye towards Saturn's moon Titan, where the gravity is lower, but the atmosphere is thicker than Earth's. And the atmosphere is actually useable as fuel. You just need to carry oxygen, which could be gotten pretty easily from the water ice "rocks" laying around. Or possibly the low gravity and high lift from the environment makes nuclear powered flight possible. RTG's should work really well on Titan, because the "cold side" would be really cold and have the benefit of radiative, and conduction/convection cooling to create a nice thermoelectric gradient due to the atmosphere. Or maybe run a Sterling generator. (Need Birdman!)

IIRC, if your space-suit was light enough, and with some extra fabric and struts, I think it's even possible for a human to fly on Titan by flapping their arms due to the low gravity and thick atmosphere.

SpaceX won the bid for the NASA Human Landing System for the Artemis missions.  Right now they're the sole source provider for a landing craft to ferry humans from the "Lunar Gateway" space station to the moon's surface.

Blue Origin and Lockheed Martin are very frustrated by this, there are hints of legal challenges and back room lobbying to come.

But the selection of a Starship variant craft as the HLS winner is cataclysmic to OldSpace.  The shock waves will take several years to subside.

Looks like they ran out water.  Seems to be two fires.  Expecting a big kaboom any time.

ETA:  Water cannons back up.  Fire looks to be diminished.  Water cannons now turning off.

Honest question.  Do we have any proof they actually executed the belly flop properly?   They launched on a cloudy day and the video conveniently cut out during the maneuver

Looks like they've got SN15 secured.
I was thinking they would have something to latch on to the landing legs and it appears that's just what they may have done while awaiting the arrival of "Tankzilla"

Looks like some of the heat tiles on the bottom test patch fell off at some point.  Excellent feedback for higher altitude tests though.

I'm kind of hoping they try something a bit more "vigorous" with SN15 after they get a chance to examine it thoroughly; Instead of a slow climb to 10k meters, a rapid climb to 100k or as high as they can reasonably get it with only 3 raptors and the max partial fuel complement those 3 engines can lift.  Obviously they're not going to be able to SSTO it so I'm still just talking up and down with no horizontal component.  But maybe get some data on a little bit of reentry energy, compare temps on bare skin vs shielded sections.

Noticed only two of the raptors lit during the flip. Did Elon revert back to only lighting two or was there a failure in one of the raptors?

I don't know, did you ask him?

Dear Elon
Why did you only light two raptors during SN16's flip?
And do you have that $500 million you owe me?

Thanks

I was listening to NASA Spaceflight and they said that it was part of the flight profile.  They cannot throttle down the raptors that low so they just turn one off and the other 2 compensate.

With SN8 & SN9 only two were lit during the initial landing burn. After SN9's raptor failure during the landing burn leaving only one they started lighting all three and then shut off the unneeded third if all three lit once it was known they had two good ones. With SN15 it appears they only lit two this time. Whether that was a revert back to the original way due to higher faith in SN15's revised raptors or it was because of a failure I haven't heard yet.

I was wondering if he would do that.  Getting more time on it seems logical since it had a nominal flight the first time.
