Astronauts are about to launch on a used rocket, inside a used spacecraft
This Crew-2 mission is scheduled to launch from Kennedy Space Center at 09:49 UTC on Friday. Weather conditions appear favourable, but if there is an issue SpaceX, has a backup opportunity on Monday at 08:48 UTC

A deep dive on why exactly Starship bellyflops (and why so close to the ground)

Why does Starship belly flop?
Why is SpaceX doing the belly flop with Starship? Why are they going from belly flopping and then flipping to tail down and why are they doing that so close to the ground? Why don’t they just start the flip maneuver earlier and ensure there’s enough time…

<b>Would there be a significant downside to using a drag producing device to initiate/perform the belly-to-tail flip instead of using engine thrust?</b>
I am <strong>NOT</strong> suggesting using any kind of parachute or other drag device to substantially arrest Starship's descent. A parachute big enough to substantially arrest a spacecraft the size of Starship would be heavy, expensive, and would likely open up a large chunk of new issues to deal with.But I have often wondered why you couldn't deploy a small drogue chute or drag ribbon as a 'pivot assist' in the moments before landing. SpaceX obviously has the 'falling with style' portion of the re-entry nailed - they have proven that they can descend belly first, using the movable fins with excellent control, and position themselves as required right over the landing zone. They have also proven that they know how to calculate needed thrust settings in order to make an accurate and reasonably soft pinpoint landing at close proximity to the ground . Vast simplification here, but most of the trouble they seem to have had landing Starship has been in the transition from belly-first to tail-first: pressurizing the header tanks in various ways in order to get an initial Raptor ignition that will provide enough thrust so that the fuel will settle in the tanks, ensuring that no vapor bubbles get passed through the turbo-pumps, when the rest of the engines ignite.If they could fire a small drogue chute or other drag producing device from the nose at - say 500-800 meters AGL - as soon as that device deployed, it would produce a pull on the nose that would simultaneously start the desired pivot from horizontal to vertical in a gentle and controlled manner while also providing enough deceleration that the fuel would rather quickly settle to the 'bottom' of the tanks, allowing the Raptor(s) to be ignited with much lower risk of vapor ingestion. Once Starship is within 20 degrees or so of vertical with a Raptor or two lit, SpaceX has all of their experience and code at the ready to either softly land on its own legs, or maneuver to be caught by a tower, with excellent efficiency and accuracy.​Pro's:I think it would be fairly fuel neutral, or even fuel positive. You wouldn't need to ignite the engines in order to start the pivot - you could wait a couple of seconds until the fuel settles due to the pull from the drag device. It wouldn't take much pull from the drag device to settle the fuel - IiRC the fuel settling operation when in orbit is done with small cold-gas thruster.It would be either neutral or a net positive for systems complexity. Drogue chutes, deployment pyrotechnics, and their associated controls are well understood devices that would likely not introduce significant new complications. And using such a device might allow for removal or scaling down of some of the current equipment installed, such as the CPOVs and header tank system.I don't think that it would be a significant weight penalty. I am talking about a small chute of maybe 3-4 meters in diameter as a SWAG, along with a small launching charge/tube and a cable/attachment hardware.150KG's? 200KG's? And if this system allowed for other more complex hardware to be removed, it might be fully weight neutral. I am -not directly comparing the two systems, but there are existing whole-airframe parachute systems for small aircraft such as the Cessna 172 and Cirrus: such systems contain activation hardware, a rocket-assisted launch system to rapidly move the chute away from the airframe to avoid entanglement, the parachute itself, and of course an attachment harness. The manufacturer, BRS states the weight of such a system at around 85 lbs/38KGThe same process, obviously with a larger drag device tailored to the less dense atmosphere, could be used for landing on Mars. It has (more or less) already been done successfully twice for the last two Mars rovers.​Con's:- The only one I can immediately think of is the chance…
