message from the Mars

http://www-star.stanford.edu/~joe/dish.html


Lately, this dish has been used to receive the very weak UHF signals from
the Mars rover Spirit. These signals were never meant to be heard back here
on earth, rather, they are the Mars ground to orbiter comms which are then
forwarded to the earth via the orbiters. We can, using some very good low
noise amplifiers and signal processing, hear faint traces of these UHF
links. This provides JPL with indication that the lander is in good health,
particularly during the times when the Mars orbiters are out of range and
before the rover's high gain X-Band comms antenna is deployed.

Watching the landing broadcast on CNN, it was announced that Stanford had
first detected the signal after landing, but by all appearances they
received the news deadpan at JPL until the signal was picked up on their own
DSN. Did Stanford ever get any credit for that?

Why should they get credit? Is it particularly challenging to eaves drop
on the signal? Seems kind of like giving credit for making a movie to the
first person in the theater.
