Nope sorry its not snoopy But if its still functional it can do more science

"In order to interact with the spacecraft we will need to locate the
original commands and then develop a software recreation of the original
hardware that was used to communicate with the spacecraft. These are our
two greatest challenges."

Given that this needs to be achieved by mid-June, it seems completely
unrealistic, regardless of funds.

You underestimate what can be done with software, which is very odd
considering the blind faith you put into hardware development of
Skylon/SABRE).

Firstly, this isn't something that has to be perfect since there had to
be some allowance for tolerances in the original specs. Secondly,
software driven digital signal processing is pretty much off the shelf
these days. As one of my (software developer) co-workers likes to say,
"Once you nail down the software specifications, the rest is only
typing".

In addition, if I understood the interview on NPR today with Keith Cowing,
some of the work has already been started.

The biggest thing right now is building the transmitter and getting it in
place. Only some of the work is time critical.

The issue is not what can be done with software, but what can be done
with it in the specified time-scale. These things always take longer
than one expects.
