NASA’s changing goals for Orion

Filed under: Politics, Space, USA — Tags: , , , , — Nicholas @ 09:56

The ever-sarcastic Lewis Page looks at how NASA has been trying to reposition their planned Orion spaceship:

NASA has declared that its pork-tastic Orion moonship — whose primary mission disappeared with President Obama’s decision that there will be no manned US return to the Moon — is now to be a “deep space transportation system”, suggesting that the agency plans to send it on missions beyond Earth orbit.

It remains unclear how the newly-renamed Multi Purpose Crew Vehicle (MPCV) will travel into space, when it will do so and what its destination might be — though a near-Earth asteroid is a likely possibility. A major reason for Orion’s continued survival appears to be ignoble porkbarrel politics — but there is a tantalising possibility that it might fly beyond Earth orbit in the relatively near future.

What Page calls NASA’s “pork map” shows why the MPCV has strong, bi-partisan political support regardless of its actual utility for the space program:

Regardless of the political support, however, the most likely view of US federal government finances indicates that Orion/MPCV won’t be viable in the proposed timeframe. There’s a non-governmental choice, however:

Famous geekbiz-kingpin Elon Musk and his upstart rocket company SpaceX have come from nowhere in just eight years to successfully test-fly their brand new and very cheap Falcon 9 rocket and Dragon capsule, already apparently quite capable of performing the ISS supply mission. Only a few years ago, many in NASA and the established industry were arguing that this would never happen.

It’s also no secret that Musk and SpaceX are working on a new Merlin 2 rocket engine, much bigger than the current Merlin 1 which propels the Falcon 9. A multicore heavy lifter based on Merlin 2 would be in the 100-tonne-plus realm required to mount a Mars mission, and will surely be the cheapest offering competing at the 2015 heavy lift Mars-rocket decision.
