Re: FW: [mars-net] Timeline for the MRO UHF In Flight Checkout



Eric,

Thanks for the post. I was wondering, where can one go
to find up-to-date position information so they can
point their antennas at MRO? Will the orbiter be too
far away for a high gain CP Yagi to hear by September
21? 

Thanks!
