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 -------------------- |

I can't wait to see these arrays come online. They have so many advantages over the large dishes for deep-space communication. You can choose how big an aperture you need to support a communications session and just use some of the dishes, reserving the rest for a simultaneous communications session with a different spacecraft. You can always have some fraction of them offline for routine maintenance without affecting communications schedules. If they're built to a common design, they'll be cheaper to maintain.
A question: three 18-meter dishes is equivalent to one dish of what size? Does it scale directly to the area, so that the three-dish array is equivalent to one 31-meter dish? --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
