Orion launch on Thursday given go-ahead
The Thursday test launch of an Orion capsule has been given the go-ahead.
Many of the news reports this week about this test flight have referred to Orion as “the spacecraft that will take humans to Mars.” I must note again that this is hogwash. No humans will ever go to Mars using Orion. It is too small and does not have the capacity to keep humans healthy and alive for the year-plus-long flight time necessary to get to and from Mars.
The most Orion can ever be is the ascent and descent module for a much larger interplanetary space vessel, used just for getting humans up and down from the surface of the Earth. The spacecraft that will really take people to Mars will have to be something more akin to Mir or ISS, a large assembly of modules put together in low Earth orbit.
One other tidbit everyone should know about tomorrow’s test flight: Though it is being touted as a test of Orion’s heat shield, the company that makes this heat shield has already abandoned this design, so the test itself is for a heat shield that will never be launched again on another Orion capsule. In addition, the flight won’t test the rocket to be used, as the SLS rocket isn’t ready. Nor will it test the capsule’s life support systems, which are not on board.
Which immediately raises the question: Why in hell is NASA even bothering with this test flight?
Sadly, I can answer that question. This is all public relations, an effort to lobby for funding. That’s it.
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
