Just read this interesting article about LRO
http://science.nasa.gov/headlines/y2005/28apr_lro.htm QUOTE "This is the first in a string of missions," says Gordon Chin, project scientist for LRO at NASA's Goddard Space Flight Center. "More robots will follow, about one per year, leading up to manned flight" no later than 2020." One per Year? Is this just wishful thinking or have any tentitve plans been mentioned for follow up missions after LRO? If the next one is going to be 2009/10 then I guess some desisions about it will have to be made fairly soon. James -------------------- |

Back to LRO. I never understood the "problem" caused by the Delta II spinning third stage. Many spacecraft with lots of liquid propellant (Near, MGS, MCO, Odyssey, Messenger) launched with this stage with no problem. And the delta V to enter lunar orbit is about the same (1,000 m/s) than entering orbit arround Mars.
I guess the switch to EELV has been because of mass issues and/or political reasons (away from Delta II, more EELV launches). Analyst |
