SpaceX makes first stage recovery and reuse look routine these days. In March, Elon Musk said he wants to start trying to recover and reuse the second stage... Why is that a bigger deal than the first stage? Find out!

what would happen if you de-orbit a glider ? using the velocity and air to de-orbit as slow as possible (bouncing of the atmosphere)

How about (keep in mind that by making the second stage reusable, the cost of the mission is MUCH LOWER) they spend a little more money on making the f9 bigger, and the first stage with more fuel. Upon reentry, the second stage will have just enough fuel to burn 0.1 percent the whole time, which will give it stability to point down, heat shield first. Boom!

What are talking about, "It was thought to be impossible." The first stage was recoverable and was recovered in the shuttle. If your trying to say, to have it land vertically was thought to be impossible is another argument.

Why not design the second and third stages of all Spacex products in such a way that pieces in orbit can be caught and cannibalized for parts to be used on Mars trip vehicles etc?

Is it possible if we use parachutes instead? And maybe have a inflatable heat shield on where the engine is? That way it will become way easier to recover the second stage

Hello Tim, do you think that SpaceX might possibly want to and be able to scavenge the second stages from orbits, using the superheavy starship maybe? Maybe even disassamble them at the orbit and bring only the most valuable parts back on Earth or possibly even reuse them in space?

Answer: do the Kerbal approach. Just put parachutes on it.
William Mulreed

Also the second stage would have to use its fuel to do a deorbit burn as well as land so the payload capability would be lower to reserve enough fuel to deorbit/land

If I understand correctly, the merlin engines are the same but with a different nozzle. Could they potentially find a way to jettison the "extra bits" of nozzle and still be able to use that engine?

SpaceX you could just add a third stage and reduce the second stage then it will automaticly re enter because it never reached orbit

Excuse my ignorance - what actually happens to the second stage at the minute, does it simply remain in orbit or does it burn up in the atmosphere?

They deorbit the second stage either it burns up in the atmosphere or if it survives it goes into a secluded part of the ocean

Why not have a heat shield that can be moved over the engines after the re-entry burn, and discarded just before landing? No fins or separate landing rockets.
Caleb Waddell
Caleb Waddell Pirms 8 Mēnešiem
Idk, I'm able to deorbit my second stages without a heat shield and with the added weight of batteries and solar panels on the stage itself as well as parachutes, and I successfully did it every time. I will say my payload was more like that com sat tho. But, I was able to get a com sat into mun orbit and deorbit the stage.
Malcolm David
Malcolm David Pirms 8 Mēnešiem
How about a Falcon 'Extra' Heavy with 4 boosters ? Surely this would allow the extra kit to be carried for re-entry and landing with a similar payload. The 2nd stage could then be re-designed so the tanks are jettisoned to remain in orbit for future re-use with only the main engines and expensive bits returned. Then use a heat shield designed with an engine [for landing] set in the centre. ie Fight fire with fire and bring it all home !
Dan Neal
Dan Neal Pirms 8 Mēnešiem
What if we created a Falcon Heavy Plus with FOUR additional First stage components. You would probably have to build up the structure of the core (hence more weight) to take the load, but I think the added Delta V would make up for that making the system completely reusable. You might also have to land all of the boost stage components at sea, or maybe not. It would be an interested case to run through Kerbal.

Hmmm, what if you didn't need the second stage to return immediately? Could you deploy some sort of solar sail that gradually slowed the stage down enough to reenter safely?
Hello World
Hello World Pirms 8 Mēnešiem
Ben Scott That would only really have any effect a couple of km before earth, you would have to do a burn to slow it down enough as otherwise it would be completely ripped apart and would burn up

Chris Townley

Once the second stage has completed it's mission, deliver a payload to space, it is lighter by the weight of it's payload, so you over simplify. Now can you factor that in and give another run at the subject please?
Chris Townley
Chris Townley Pirms 8 Mēnešiem
The second stage is also lighter by the amount of fuel used to do its task. Reducing the Orbital speed while in vacuum and possibly going for a parachute return through the atmosphere may work. the second stage at altitude will not accelerate the same as, say 10K as the gravitation is less. A Drogue as it gets into a denser atmosphere will increase its breaking effort.
