NASA has revised their plans for the 2017 and 2021 flights of its Orion capsule, making both flights more ambitious.

The competition heats up? NASA has revised their plans for the 2017 and 2021 flights of its Orion capsule, making both flights more ambitious.

[M]anifests have always pointed towards the first SLS/Orion launch being an uncrewed Exploration Mission (EM-1), which was baselined a validation flight that would send Orion on a 7-10 day mission around the Moon.

SLS and Orion would then endure a four year gap – again, mainly due to the advanced 2017 debut relating to ISS crew back up – before repeating a version of EM-1, this time as a CLO (Crewed Lunar Orbit) flight, with four astronauts spending three to four days orbiting our nearest neighbor, as opposed to heading directly home after passing around the Moon – a flight known as Exploration Mission -2 (EM-2).

Much to the surprise of some people deeply involved with SLS and Orion, the order came down from NASA HQ to realign EM-2, based around a 2019 mission tasked with hunting down and capturing an asteroid that would then be placed in the vicinity of the Moon within one to two years. EM-2 is also known as the Asteroid Redirect Crewed Mission (ARCM). [emphasis mine]

It has been my understanding that the plans for the 2017 unmanned test flight have previously described it as sending the Orion capsule into a high several thousand mile orbit, not to the Moon, in order to simulate a re-entry from lunar distances. Making that unmanned mission a lunar orbital mission makes it far more challenging. Similarly, it is incredibly risky to turn the next flight, the first manned flight for Orion, into a duplicate of this mission, or a flight to an asteroid. This will be the first time humans will have ever flown on Orion, and only the second time the capsule has been used. To then send those humans to the Moon or an asteroid seems downright foolish. Even the 1960s NASA, which was quite willing to run risks, would not have attempted such a plan.

It is my guess that the White House has recognized that SLS can’t survive politically with a launch rate once every four years and planned test flights that aren’t very exciting. They are therefore pushing NASA to accelerate the second mission (and first manned flight) from 2021 to 2019, while also making both flights more ambitious and therefore more salable to the public.

Whether this is possible, given NASA’s bloated bureaucracy, is the main question. Moreover, even at this accelerated pace SLS will be competing directly against the private sector, which I expect will continue to do things far faster and, more importantly, far cheaper. Against that competition SLS will be hard put to survive.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

    I couldn’t believe this when I first heard about AND I can’t believe it now!
    Why would we spend this amount of $ on this? Why!?
    Spacex is about to launch their F9 v1.1 in sep and the heavy Falcon soon. Approximately @ $65-75 mill and $85 mill (I think)
    Per vehicle, respectively. Save $ and use their rockets!!
    Doesn’t take a rocket scientist to add this boondoggle up to a lot of loss-$$$$$

    At Orions present schedule it will be old and out of date by the time it makes its third launch.

    Just like the Shuttle.

    I bet they plan on upgrading its electronics each and every time it flies and doing an almost total rebuild of the craft in order to do it.

    All it is is an employment opportunity for them.

  • It has been my understanding that the plans for the 2017 unmanned test flight have previously described it as sending the Orion capsule into a high several thousand mile orbit, not to the Moon, in order to simulate a re-entry from lunar distances.

    The first test launch of the Orion in 2014 is to be on the Delta IV Heavy, not the SLS. That is the flight just to send it on a several thousand mile high orbit to test its reentry capabilities. The first test flight, unmanned, of the Orion on the SLS scheduled for 2017 was intended to be circumlunar. Then the 2nd flight was intended to be manned that would also be circumlunar.

    Actually if you run the numbers the Delta IV Heavy test of Orion can go all the way to the Moon to do the unmanned circumlunar test. So using the SLS for this would be unnecessary.
    Also, a lunar lander can be derived from the Centaur upper stage. Such a smaller lander than the Altair that was derived from an existing vehicle would be much cheaper than the Altair. Then that 2017 Orion/SLS flight could actually be an unmanned lunar landing test flight.
