NASA To Contact Its Oldest Spacecraft 111

Re:Delta S (Score:1)
You need to square each term.... :-). We could have chosen time units overall, and measured physical lengths in time units, but I chose not to, since it usually isn't done that way. The quantity dS is the spacetime interval between the two events, dx is the physical distance between the two events as measured in a particular inertial reference frame, and dt is the time elapsed between the two events as measured in the same frame. The important thing is that dS is a frame independent (Lorentz invariant) quantity, so all observers will agree on the measurement of dS^2, although not necessarily dx or dt.
(dS)^2 = (dx)^2 - (dt)^2
where we measure time in length units (set c=1, the way real physicists do it
When ds^2 > 0, the two events are spacelike separated, meaning that the two events could not have affected each other (they are not causally connected, in the lingo), as they are farther apart in space than the distance light signals could propogate given the measured time difference.
When dS^2 timelike separated, meaning the two events could have affected each other (light could have propagated from one to the other in the time measured, with time left over, meaning (potentially) other types of particles could have travelled from one to the other).
Finally, when dS^2=0, the two events are null separated, or light-like separated, since the two events could only have affected each other by light signals.
Using measurements of intervals from many different events, we can (approximately) reconstruct the metric.

Very little, I'm afraid. There are many more very good instruments, most notably SOHO [nasa.gov], TRACE [lmsal.com].
However, for a amateur science project, it would be great, as you're working on data from a spacecraft that made history, and you're the only one who does it.
The question remains, how expensive it would be to build an antenna to downlink the signals.

My signs may be wrong, but
delta S = delta x - (c * delta t)
Unfortunately, I also forget what it was called. I do remember that whether it was positive or negative had some significance, though. If it was positive, there was an inertial frame of reference in which the two events that the delta was measured between were simultaneous. If it was negative, there was an inertial frame of reference in which the two events occur at the same point in space.
Also, check out the units - distance.

Re:What hardware is it running? (Score:3)
NASA is open about such things, but based on my experience with the UARS satellite, much of the protocols were one shot solutions applicable only to the particular mission or mission family. If the thing's still up and running you've got a good shot of getting everything on the web. However, if it's been shut down for more than a couple of years, they probably tossed the binders containing the documentation. That was a big problem even on a working project like HRDI and UARS were during the early 90s. Namely it had been running for a several years already, the software was getting long in the tooth and it needed updating. A lot of my job was tweaking legacy code to to bring it in line with language updates and whatnot. Its really frustrating to be able to find no documentation whatsoever on a critical piece of running code. And, thats from the programmer's point of view. I don't wanna think about ther operations engineers would have done if they had to restart it. Anyway, searching for lost documentation would be an original science history project. It'd also be fun to go through the old software archives and take a peek at the code. Mind you for something this old who knows how its stored--punch cards? It kinda gives the creeps to know that someday a historian may draw an image of me based solely on a bunch kludgy Fortran 66 and VAX DCL programs.

PAWS allows us longer timeouts and large windows, so once implemented ftp to mars will work nicely.
Using TCP for any small-packet transmissions on a high-latency connection is ludicrous. TCP (as opposed to the simpler UDP) guarantees delivery in packet's original order, or the socket dies. It does this by sending back receipts to each routing step. You can "assume success" for a while, but if you do, why not use UDP without all that receipt time?
