Laurie Leshin attempted to tamp down the mindless hysteria over the new space policy yesterday:
The new plan represents “a change in approach and philosophy, but not a change in goal,” said Laurie Leshin, NASA deputy administrator for exploration, in a speech yesterday at a Marshall Institute event on space exploration policy in Washington. “The goal remains the same: to see human explorers out in the solar system.” The new focus on “sustainable and affordable” human space exploration isn’t that new, she said, noting that it was emphasized back in 2004 by the Aldridge Commission that evaluated the Vision for Space Exploration (a committee she served on when she was a professor at Arizona State University.) “We’ve come back to needing to have new and enabling approaches in order to make this a sustainable program for the future.”
To emphasize the need for technology development—one of the cornerstones of the new plan—to enable sustainable human space exploration, she put up a chart showing the mass needed to carry out the latest version of NASA’s Design Reference Mission for human Mars exploration. “If today, with today’s technology, decided we wanted to go to Mars, our mission would have a mass about 12 times of the space station,” she said. “It’s just impossible.” Various technologies, from reducing cryogenic boiloff to in situ resource utilization, can get it down to a more manageable level, she said. “It’s not that these technologies are nice to have, they’re absolutely required if we’re going to have a sustainable path out into the solar system.”
I wish that people would understand what a hopeless dead end Constellation was. Regardless of the new policy direction, its rotting carcass had to be cleared from the road. I assume that we’ll be seeing a lot more details and specifics in the coming weeks and months (probably at the National Space Symposium in Colorado Springs in a couple weeks).
[Update a few minutes later]
One of the things that encourages me about the implementation of the new policy is that Dr. Leshin, the new head of the Exploration Directorate, was on the Aldridge Commission, and understands better than most the need for affordability and sustainability recommended by that body. I suspect she’ll do a lot better job than Mike Griffin’s NASA of implementing all, or at least most of the Aldridge recommendations.
