I came to post this video before seeing all the CGI nonsense. I hope this thread doesn't get muddled up with all the conspiracy theories that distract from good discussion in the way that so many other great videos of space flight achievements do when they devolve into flat earth debates and faked moon landing nonsense.

These are epic achievements that will lead to game changing technologies. There's no room for conspiracy trolls here.

I know a lot of people everywhere feel vested in this - and you can tell that so well in that video. I was sitting on the side of an FM highway yesterday flipping between YouTube and the binocs trying to spot it - but I was just too far away.

My wife came in the office yesterday just as it was descending. It landed and I was really excited and she was smiling. I asked her "you realize you are watching the first steps to humans becoming interplanetary?" and told her what starship is designed for. She really wants to watch future launches now.

Yes, it really is amazing to watch this unfold.

I will however cast doubt on the youtube title... I don't think those are SpaceX employees. That's a river they are looking across, and it's from the south. If you look at a map you can tell they are looking at this from just south of the Rio Grande in Mexico. Why would SpaceX employees travel to Mexico when their facilities are much closer?

ETA: NM, PJ is right. I got my bearings mixed up

I think the same, those in Mexico can get MUCH closer than here in the States.

I just realized that the launch site at Boca Chica is actually 2 degrees latitude further south than Cape Canaveral.

So what's the velocity boost that Starship gets compared to something leaving from SLC-37?

Boca Chica is at +26.223
Canaveral is at +28.444

Any ideas how they could make (bigger) landing legs that could protrude outward after a re-entry? It does seem like a challenge if they are not going to be housed somehow inside the engine bay vs. a F9-style flip down.

But again precisely controlling that one raptor is perhaps something they will get much better at over time. It might explain why they want to 'catch' the SH, too.
SpaceX knows these little legs are junk. They are not the final legs. Landing for re-flight isn't the priority yet. Learning how to fly this corn silo is the priority. Each one of these SN's is a single use prototype. When it's time, they'll install better legs.

I hope they were able to download all the information they needed before it blew up.

I am sure the engineers would have really loved to inspect the flight hardware, especially the raptors.

They're more T Rex arms than legs right now.

They definitely changed plans.

First was 2 burned all the way.

Next plan was light 3, then burn 2 for landing. Never tested.

This time they lit 3, then only burned 1 for landing. I think that's the best answer because you can use all 3 to decelerate and make sure you're stable, then running only 1 allows you to keep the throttle in a more reliable range.

Higher flow likely means better response to changes in throttle as well.

Wonder why it landed so hard after all that - it really seems like they did the hard part right.

Are you certain the intention was for two engines to turn off?

Listening to the live SpaceX feed, yes the intention was to turn two engines off. Maybe he misspoke but that's what he said.

Good to know, thx. I also would have to think they'll have a better 'system' for the lunar one, if they get to build it. That looks like a laughably bad plan for a powdery, soft planet.

That just made me think about the one engine landing. Can they throttle down a raptor enough to land on the moon?

Both are valid points. I'm gonna guess the moon one will have a single 'smaller than raptor' engine as well for that.

I also think it has to land straight up. Picture one somehow landing crooked on the moon, with astronauts, and tipping over. Not a good look. (Note that it won't have to belly flop down obviously, but it will still have to do that eventually on mars).

Oh sorry I missed this question. Yes without a doubt they did the landing with only 1 raptor on purpose. I can't imagine they're at the point where they could light 3, turn off 1, LOSE 1, and still land! In fact I think they could land on 2 if they wanted but for now are trying to stay out of the lower throttle areas until they get a better handle on the engines.

I don't think they'll use the raptor to land on the moon, they'll have some rockets up closer to the pressurized sections (maybe Dracos) for the propulsion.

Last I read there will be 3 sea level optimized and 3 vacuum raptors on a starship. I assume they will be using the vacuum optimized raptors for moon landing and space travel. The "Sea-Level" optimized will be used on Earth (obviously) and Mars.

Here is a photo comparison:

The minimum thrust level of the sea level optimized raptor is still greater than necessary for a hover of Starship. Elon has discussed this in detail going back to the Falcon 9 rockets when they solved that problem. Even the Merlin engines used for landing an empty F9 are powerful enough to produce positive acceleration.

Therefore, the ignition sequence of the landing is not so much about thrust as it is timing...The optimum thrust (or any thrust for that matter) level will occur based on the incoming velocity of the vehicle relative to its landing target. Ideally, they optimized those to a "reliable" level. Landing the "inverse pendulum" problem was solved...and they even did it on a drone boat in the middle of the ocean. Talk about confidence.

Hence, gravity is just a variable in the velocity and timing sequence of the ignition. Whether it is acceleration due to the earths gravity or due to thrust while entering the lunar "atmosphere"...Timing the exit of the belly flop is the only real issue they are having.

Lastly, I would consider Boca Chica's silty/sandy surroundings comparable to that of the moon... I would bet they will land/launch from the beach one day.

Yes and No the engines for the moon lander are right below the crew area to prevent dust sent up during the landing.

I believe they will also have thrusters at the bottom (not sure) but the engines for the actual moon landing will be 2/3 of the way up the starship.

I doubt they want to use hypergolics, period, on a Starship, but I also think Elon is really trying to win this bid and it might help. Certainly, he was ticked at how little SpaceX got as far as workshare/funding so far, both for the lunar competition at nasa and space force, and I could believe any risk-reduction components that would help in the selection this month/next would go all out to move forward, even if it's not a long term path they want to go down (for Mars etc.) Whatever they are bidding for a starship lunar lander is...vastly a different ship than what we've been watching so far in Boca Chica.

Now, I do expect the NASA award to be political by nature (as Nasa has been since it was formed), but again Blue Origin got a ridiculous 4x share of the previous award, and Biden's team wanted more time to review the bids, so it will be interesting if in fact it is "business as usual' for the next award or, if somehow NASA takes a risk. (I personally favor the dynetics team for first place, but why not challenge both to get it done?)

Who thinks Blue Origin could 'seamlessly transition' from development to testing based on their 20 year history?

Quote:

NASA last week quietly delayed its plan to award two high-profile crewed lunar lander contracts, moving the finish line back two months for a crucial program under the Trump administration's hasty timeline to get astronauts on the moon in 2024. With short funding from Congress and a new administration focused on more pressing national issues, the move was expected.

Elon Musk's SpaceX, a team of aerospace giants led by Jeff Bezos' Blue Origin, and Leidos-owned Dynetics won a combined $967 million in seed funding from NASA last year to develop rivaling concepts for a human lunar landing system. It's the space agency's first effort to spend money on astronaut moon landers since the Apollo program in the 1970s.

Last Wednesday, NASA told the three contractors that an extension to their development contracts "will be required," picking a new award date of April 30th. Under the Trump administration's timeline, the agency had planned to pick two of the three bidders in late February, giving a stamp of approval for two systems that would inevitably carry humans to the moon.

The delay was all but certain: The spending bill Congress passed in December gives NASA $850 million for the Human Landing System program, far short of the $3.2 billion it needed to stick with the 2024 timeline. But NASA remained committed to the February award date and, similarly, the 2024 moonshot. A delay was also expected as Biden's team holds off on releasing any space policy and focuses more on climate change and curbing the pandemic, keeping the long-term fate of NASA's Artemis program uncertain.

Now, NASA says the delay is designed to give it more time to evaluate the bidders' proposals and to "preserve the ability to seamlessly transition" from the development phase, but added it may not need the full extension period and could award the lander contracts earlier. The extension also gives the companies more time to design and develop their lander systems, NASA said.

SpaceX's lunar lander pitch to NASA is Starship, a roughly 16-story-tall fully reusable vehicle the company has been launching and landing in short, suborbital test flights called "hops" in Boca Chica, Texas. The company's chunk of development funds was $135 million.

Jeff Bezos' Blue Origin got the largest award, $579 million, to develop its Blue Moon lander. The company announced a "National Team" in 2019 comprised of Lockheed Martin, Northrop Grumman and Draper to work on the project. Dynetics got $253 million for its lander and has partnered with Sierra Nevada Corp.

The Biden administration has yet to pick its NASA administrator or release any space policy objectives, but is expected to slow down the Artemis program's sprint to the moon by 2024 a date widely viewed as unrealistic. This month, the administration announced its team for the White House's Office of Science and Technology Policy, picking pioneering geneticist Eric Lander as Biden's top science adviser.

South Padre is the best spot, plenty of people watch from the beach. It's about 5 miles as the crow flies, which is closer than anyone but the press get to a launch out in Cape Canaveral.

For the best view, The Pearl Hotel has rooms that face the launchpad and I think they have special packages for launches.
