For those who haven't seen them, there are some really interesting presentations at the LRO Project Library. Be sure to check out some of the LRO Project Science Working Group (PSWG) presentations.

Check out the LRO's new Assembly Update of April 24, 2007 -
http://lunar.gsfc.nasa.gov/042407.html On that page, there is a link to a Hardware Gallery of images. The first signs that the LRO is coming to life! Another Phil |

Kewl! You just don't know how much I'm looking forward to seeing what LRO comes up with. I have a deep and abiding interest in selenology. Comes from having been 13 years old in the summer of 1969, I think... *grin*...

Goddard have unveiled a new antenna farm at White Sands that will support LRO:

$20m for 3 new 18m dishes - but assuming a scaling of the third dish costing half as much as the second which cost half as much as the first ish... perhaps only $3m each for future dishes
250 sq m 70m dish is about 15,400 61 dishes - call it $200m for a 70m class array...maybe. With HUGE flexibility. Doug |

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.

I assume it scales with area, but there's probably a proviso regarding losses when combining the antennae - I'm not sure how much that is though.

Aghgh - I hate headlines that use something that MIGHT happen, as fact.

Lunar Reconnaissance Orbiter:
http://www.nasa.gov/home/hqnews/2004/dec/H...ar_orbiter.html The angular resolution of LROC imager will be about 50 cm/pixel (dependent on the final orbit of course). With this resolution it will definitely be possible to spot the Apollo hardware such as Lunar Module descent stages and the 3 Rovers." |
