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



Hi,

You can try here:

Thanks for the post!

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!

 Dear "Deep Space" Radio Amateurs,
 
 Here is the timeline for the MRO UHF In Flight
 Checkout.  Please note
 all times are spacecraft event times UTC (SCET). 
 Good luck!
 
 Sincerely,
