Today, Elon Musk suggested that SpaceX will abandon its plans to land the company’s Dragon capsule on Mars — a mission the company had been aiming to do as early as 2020.
SpaceX will not fully develop the landing technique it was going to use to land the Dragon on Mars. Known as the Red Dragon mission, the capsule was meant to lower itself to solid ground using engines embedded in its hull, and then touch down gently on landing legs in a method known as propulsive landing. But Musk said the company will come up with another way to land vehicles on the Martian surface.

Airbus and Boeing are going out of business! Still all surrealistic too me ??

Their Can Do spirit reminds me of the early days of NASA before the bean-counting bureaucrats in D.C. began siphoning the life out of the agency. I assure you, with Musk at the helm, this will NOT happen to SpaceX.
Francoflier wrote:BFR is not only a man-rated fully-reusable clean-sheet design, it is the most ambitious spacecraft ever seriously considered. It would surpass the Space Shuttle, the most complex flying object ever created by every metric, and the largest space exploration budget in the World could barely keep up with the costs of flying a handful of them, not to mention their lacking reliability and safety issues.
AvObserver wrote:"QuarkFly, I think you'll live to eat your opening words in this post. Musk's admirable persistence is paying off, sometimes slowly and painfully but he's getting there. And while Mars may not happen in the timetable he suggested; SpaceX is on its way to getting there...."

VSMUT wrote:In 2016, ULA said the typical cost was 2 billion USD, and that their own Vulcan was a bargain at just 1 billion USD. And thats a non-reusable rocket.
500 million USD is about what you would pay for 2x 77Ws...
QuarkFly wrote:.along with the fact Mars is just a lousy place where nobody will want to stay -- makes the whole idea a pipe-dream.
QuarkFly wrote:True, but Falcon-Heavy is a derivative of Falcon-9,...Yes, significant modifications were necessary as Musk said -- but it is basically Falcon-9 cores and second stage.
QuarkFly wrote:But note that Musk said Falcon-heavy cost over $500 million to build and launch...that's right in line with what other large rockets cost to develop. I do think the re-usable cores are a modest breakthrough !!

OK, perhaps you are right...but the whole point of this discussion here, has been if these dreams are in any way realistic.parapente wrote:Well we do know what happens when you gear a project simply to plant a flag.You waste all the massive investment.It is a totally pointless exercise other than the flag.Indeed it could be said that such an exercise put us back decades in human space exploration
I don't know...I think a lot of things came out of the Apollo moon program, even though it was primarily a flag planting race with the USSR. We developed things that were built upon later...Large rockets and rocket engine technology, in space docking, the beginnings of space avionics...lots more. Too bad we went off on the space shuttle dead-end after that.
