SpaceX Falcon 9 Landing Follow Up
About | Information | History | Online | Facts | Discovery
Lots of questions were asked, so I thought I'd answer them while attempting the landing with Ferram Aerospace installed. Apparently the story about the stage spinup and baffles was untrue, I don't remember where I heard it, but it's all wrong, it was simple fuel starvation.

The reason they don't land the rockets on land is most of their contracts require them to be in trajectories over water

Hi Scott, I am a new KSP player, I really like your videos. Concerning the reason why Space X land the falcon 9 at sea on a barge is mostly because it s more fuel efficient. For safety reason, the space ports are next to the sea (cap canaveral, kourou, for example). After separation, the first stage reach its apogee above the sea and will crash in the water if nothing is done. To land on the ground. Space X need extra fuel to reverse the lateral velocity aquired during the ascent, so they cant send less paylod to the iss or to geosynchronous orbit. Using a barge allow them to use less fuel for the descent therefore more for the ascent. Which, once again allow them to send heavier payload to space.

Why not approach vertically and then parachute safely down
-
So, Scott Manley is also a prophet, making the exact copy of the Falcon 9 landing, 1 year before it actually happened?

They did it again! May 6, 2016: Second sucessful Landing at barge!
-
This was so amazing to watch and listen to. Scott, you are the "MAN"ley!

The boat is call the "Of Corse I Still Love You"

they landed on land

How about an aerial skyhook-like recovery system? Is this crazy idea even feasible? As long as it was unmanned and the recovery area was unpopulated you would only be risking loss of material. The rocket would release some kind of loop and then an aircraft would fly by and attempt to hook it. Of course you would need an aircraft with a massive amount of excess lift and control that could survive the forces as well as provide enough force to arrest the descent. Maybe a large flying wing like a B2 covered with thrust vectoring nozzles like a Harrier? Or a fast rotor craft? Catch the loop of the falling rocket and then reel it in gradually like a fish on a hook. Most of the mass and complexity of the vertical landing systems is thus transferred to the recovery vehicle to keep the rocket light. The rocket could of course include a parachute to slow descent and make it easier. Still seems like a very tricky maneuver to rely on but we can now hit a missile with a missile and have drones carry out complex independent missions so it might be technically feasible.

YES MORE KERBAL VIDEOS :D

For the frequency of these events, parachutes and water would be just fine.
Musk will not better the core elements of the shuttle program AND make money. -
One thing I think that you may have overlooked is the multi-engine design of the falcon 9 (9 merlin engines) is that I believe during reentry most of the time only one engine is firing, giving you actually a good amount of ability for fine control. So while you don't can't throttle your engines down past 70%, you can achieve a similar effect by changing how many engines are firing.

+Scott Manley Why not surround the landing pod with a giant "cushion"? Just let it fall on it sideways then recover the rocket no problem..
-
Very informative and enjoyable up until the last few seconds where the top of the rocket gently floated off, over the sea. I completely lost it.

He should do something using Burn Together.
-
here's something why not use deployable helicopter rotors to land the rocket motor like nasa was planning on doing, and personally something i'd like to see a video on in ksp
-
How about instead of aiming the rocket at the barge, aim the barge under the rocket. parachute the rocket so you dont need to carry extra fuel. drive the barge to where its going to land and there, isnt that easier?
-
This may seem like a dumb question, but what is a gimbal, and how does it work? I looked on Wikipedia, and it said something like it is a device that spins in one direction, and 3 make a gyroscope. What exactly do they do, and how can they change the direction of a massive rocket?

Wait... Don't they have MechJeb in NASA?
Laaaaaaame.
