      @@DavidWillisSLS A Question For You David:- How Much Money WAS Already Invested In The Constellation Program BEFORE It Was CANCELLED And What WAS The TOTAL Project Cancellation Costs?

      ​@Just Some Guy I'd say we were in hell before, the space shuttle didn't retire early, it far outlived what it was originally planned for, essentially gutted NASA, and set us back potential decades. So badly that officials have stated we already would be on Mars if not for the shuttle.

      Because Constellation planning would have ended NASA flights to the ISS after 2015, perhaps commercial crew would have been worked into keeping ISS operating, much as it does now.

    • @joshuabanner3675

      It wasn’t exactly cancelled, both of the rockets had very serious engineering concerns. Most importantly; ares 5 was supposed to use ablatively cooled RS-68s from the delta IV in a cluster, but it turned out that the heat would be too much, so they has to use regeneratively cooled engines I.e. the shuttle ones. The cumulative redesigns resulted in the SLS we have today. While the actual implementation has been disastrous, the SLS as a design was more or less inevitable.

    This was top quality. Constellation is something that’s close to me since it’s what got me into spaceflight in the first place. I was too young to experience anything to do with Shuttle but in 2014 I saw the Orion test flight on Delta IV Heavy. Makes me sad that this program never materialized. It’s so much more cooler than Artemis.

    We got the sls block 2. i doubt besides starliner and dragon making the LEO and gateway trips there is much different than the insane inefficiency of sending a starship to land 3 people. So a different lander will replace the starship, spacex can only bleed money for so long. but it is sad that until starliner launches, space X has a stranglehold on our ability to get into orbit.

    Let' s hope on the elon and jeff way cause it seems like NASA can no compete with the SLS, even Europa Clipper must lift off in the Falcon Heavy or New Glenn, if ready, because vibrations on the SLS

    Great general outline of Constellation. However, the longer Constellation lingered, the more and more unrealistic it seemed.
    The foundation for its start was a study done of what NASA should do in the wake of the Columbia disaster, which was to return to the moon and head to Mars. The resulting program was Constellation. There were criticisms at the beginning that instead of taking advantge of bold new technologies as was suggested in the Bush exploration report, that Constellation was just a big relplay of Apollo, and was not really a fundamental step forward in technology, but just something to delay an eventual Mars mission.
    By the time metal was being cut for it, its budget required that the ISS be de-orbited as NASA could not afford to keep it going and fund Constellation, and the Altair lander would have required an unrealistically large increase in NASA's budget. Also, there were some severe engineering reports, including one from the Air Force stating that the crew could not survive a first-stage explosion due to the rate of expansion of its fireball being able to overtake the escape system rocket. This was significant because a major part of the rationale in killing the shuttle was that there was no way for the crew to escape a launch problem, as had doomed the Challenger crew.
    Even the case for returning to the moon was not stated, and it did not have broad support from the public or even within NASA, as it would have been so expensive that NASA would only be able to do an underfunded Constellation and little else.
    Artemis has gained more support because it does have the stated goal of finding and making use of the moon's resources, and it makes use of commercially provided components, and apparently it requires much smaller increases in NASA's budget to pull it off than did Constellation. Politically, it gains some support by its use of the in-progress SLS and Orion, and in general Artemis is open ended and can evolve to take advantage of what we find on the moon and commercially driven technology, instead of just committing to a prohibitively expensive lunar delivery system with no clear purpose. It should be stated though, that thanks to Constellation, the LCROSS mission (that verified lunar water at the south pole) and the LRO that accompanied it, did fly on time as the first Constellation elements, and have contributed a lot to illustrate the importance of the moon to exploration.
