I guess this is less important now that NASA looks to be allowing the reuse of the Dragon 2 for crew missions despite splashing down, but it occurred to me that the even if the SuperDracos weren't to be used for propulsive landings, they could still be used in a similar way to the Soyuz retro rockets for a "soft landing" on land - there's probably some good reasons not to try this!

I know the Ariane 5 EAP have a chute based recovery system (not for reuse, just for inspection).

It was even planned for Ariane 4

[@JohnSmith-rf1tx]

I don't think the time pressure to get Crew Dragon flying was much of an issue in SpaceX's decision to drop propulsive landing. That was always proposed as a later addition to the program with all the initial missions only using parachutes. So, if anything, the most that time pressure could have done was delay when the change over occurred to a later mission. I think SpaceX dropped propulsive landing because when it came down to it NASA wouldn't support their development/testing and certification strategy which included using operational Dragon 2 cargo missions returning from the ISS to test out the propulsive landings. From NASA's perspective, this represented a major increase in risk to their extremely valuable cargo for essentially non-existent or at most very negligible benefits. And I believe that NASA indicated to SpaceX that it would take A LOT more flight testing for them to sign off on it than SpaceX had originally included. As a result, the added cost to SpaceX to certify the propulsive landing system became seriously prohibitive and it was dropped.

Hey Scott, You may or may not recall that the first fly back boosters were proposed by NASA for the shuttle. There was a tab on the Shuttles page about the future or upgrades to the shuttle. Listed was the "glass Cockpit", "fly back boosters", and maybe others. The problems they noted is that for one, they'd have to change to LRB's so that the engine could be turned off and then back on when needed. It was also mentioned about the possibility of attaching wings and a jet engine. The problems that were noted were: increased weight of wings, jet engine, and jet fuel; LRB's need to save fuel during liftoff to use during reentry, shortening the lift off burn; LRB's didn't have the required thrust to replace the SRB's. Considering the proposals of the SLS like 1 month turnaround, SLS C, satellite launching platform, lowering the cost and easier access to space, and other improvements, it might have been really cool to see what a matured system would have been capable off! Space X probably hired those same engineers that proposed the fly back booster.

Another reason for not using a single huge engine is redundancy. Where a single (of nine) engine failure is not critical to the mission, would having a single one represent a signifficant risk.

[@themoonissquare323]

The Crew Dragon relying on the thrusters would mean there is a no escape zone just before the ground, too low for parachutes to deploy but plenty high enough to kill you in a crash. If they had of gone ahead with propulsive landing i hoped they would still deploy the parachutes they had carried anyway but still make a silky smooth and soft propulsive landing with the Super Dracos. But there would be a problem with landing accuracy the higher you deployed the parachutes.

[@_tyrannus]

Of all of these, to me Red Dragon is the saddest cancellation. Starship is really overkill in terms of Mars payload, considering that there would be more scientific value from landing numerous smaller specialized payloads at distant points on the planet. Red Dragon would also have been a clever reuse of existing, actively developed hardware, rather than an expensive and uncertain original design. I'm all for Starship's success, but taking smaller steps can sometimes be worth it.

[@szdorant]

You could also ditch the heat shield if landing legs or balloons are needed for dry landing.

[@donhull2440]

Scott, in orbit Starship refueling would be a good topic for one of your videos. In orbit refueling is one of the things NASA wants SpaceX to prove before providing money to SpaceX for the Moon Human Lander System (HLS) proposal so it is really relevant. The potential danger of in orbit refueling for maned flights is also relevant. Elon has said that the Starship will need to be refueled in orbit using 6 to 10 refueling flights of additional Starships for Moon or Mars missions. Less delta V is needed for the Moon vs Mars but the Starship would need to carry enough propellant for returning from the Moon vs making propellant on Mars. It would seem to be a good assumption that the Starship would have to have a full propellant load for either destination. The fuel load for a Starship is 1200 Tonnes and the payload of a Starship is supposed to be 150 Tonne. Now some speculation. Assume 10% of the propellant remains in LEO for a fully loaded Starship and this amount of propellants is needed for Starships that land. If a special tanker version with 150 Tonnes of propellant as the payload were used the number of refueling flights is just over seven, and probably eight to take care of boil off. Any thoughts about this?

[@alexlandherr]

At 3:00, and it looks a lot like the F1 too.

[@ConalRF]

How about: Instead of feet coming out the headshield, what if the heat shield moved down with shock absorbing legs between it and the crew area?

[@Wordsmiths]

That would let you land it on soft sand, in scrub, etc. And if you accidentally land on a steep slope, legs would catch and make the capsule tumble, but just the heat shield might act like a sled: slide down a little until it comes to rest, gently.

Stuffing the parachute for first stage into the inter-stage makes sense.... Having it stuffed into the nozzle of the stage 2 engine sounds scary. They must've had a delay between staging and 2nd engine start to avoid toasting it.

[@Odd_Taxi_epi04]

Every non-soviet rocket has a delay due to the closed inter-stage. Also, the second stage exaust temperature should be around 1000ºC at less than 0.1 atmosphere pressure. Not that menacing, relatively easy to protect against for a second or two.

[@JohnSmith-rf1tx]

SpaceX has never use hot staging--where the upper stage engine ignites prior to separation--there's always been a few seconds delay between main engine cut off, stage separation, and second stage engine start. That delay allows the stages to separate a decent amount before the upper stage ignites so there's little danger to the parachutes which are stored in bags/compartments to protect them from exhaust.

I was thinking advantage of starting on one concept that includes building hardware then later abandon it to start on another has advantage of building up infrastructure for building things (ordering parts, machining, wiring up stuff, hands-on learning). As compared to lots of paper studies and then select one concept and that will continue beyond when originators die of old age. Those started Dragon got to see it fly people. Not sure for those that started Orion will live long enough to see it carrying people. I am impressed with Dragon using the Dracos for launch abort but also be used for manuveuring. Unlike Orion takes its shape because that what was used for Apollo and makes a lousy cargo carrier because door too small. Then through various foibles is this huge protective shroud with the escape tower, a lot of mass that will be thrown away but yet need it for crew escape. I sure like to hear those that designed Dragon and how they arrived at the way it is, in addition to other ideas that looked promising but turned out not a good idea.

Tim Dodd also did very good video about the aerospike engine. Are Aerospikes Better Than Bell Nozzles? - KZbin

Hi Scott thanks for your informative videos. Just wondering do you have a degree in any of the rocket sciences or it's just your passion

[@charleslambert3368]

He has a degree from Aberdeen in astrophysics and a masters in something. So he's self taught as a rocket scientist. Also he got a day job in software by being a dj.

Draco propulsive landing/travel will return We'll need personal vehicles for orbital transfer, surface-to-orbit on mars, etc

Why on -Earth- Mars the dragon on the Red Dragon visualisations is blue??

[@johndododoe1411]

Easier to spot on Mars surface, plus SpaceX and NASA logo colour.

[@luigivercotti6410]

plus if it were red it'd look like a commie rocket

[@Muonium1]

What about the tiny greenhouse on mars thing? Of course that was just before spacex, but I always wondered why they haven't done it in the 20 years since and they've had the ability for at least a decade now.

I really like these "history" videos- they're equally as interesting as the other ones :)
