  • You need to square each term....
    (dS)^2 = (dx)^2 - (dt)^2
    where we measure time in length units (set c=1, the way real physicists do it :-). 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.

    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.

  • Humph. I don't normally whine about moderation, but, but I think Farsighed and I were on the same wavelength here -- Their Satanic Majeties Request, Track 9, "2000 Light Years From Home".

    It's not terribly germane, but at least I was no more OT than the parent to which I was replying.

  • So are you going to create Pioneer6@Home, so amateurs with satellite antennas can try to contact Pioneer 6 and extract the signal from the noise?
  • It may depend upon how safe it is for others to listen to the probe. The article makes it sound as if the probe requires a command to send data -- perhaps the probe is not designed to continuously transmit, so the command code should not be made widely available.

    If the probe is continuously transmitting, then it would be nice if they'd just publish orbital elements and protocol information so everyone with a 300-meter antenna can listen in.

  • As for hardware and protocols, I guess it could be interesting as a amateur science project, and NASA are usually quite open about such things. The link posted by lemox, has the e-mail address of the project manager at the bottom of it [nasa.gov]. Why don't you contact him and ask about the feasibility of building something to downlink data and analyze them. You know, I think most old scientists would provide that inforamtion very cheerfully.

    My additional question is what practical use it's information would have today, with all the monitoring equipment we have on Earth and have sent into orbit.

    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.

  • To quote the space.com article you link to:
    "Now, nearly 7 billion miles from Earth"

The probe would disagree, saying it was a trick question as Earth did not exist 7 billion years ago.

  • The space-time metric is not unknown to us primitive earthlings. I ran into it in my second year course on relativity. It is called delta s. (I can't make that damn triangle).

    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.

    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.

    . . . . what NASA doesn't realize is that the aliens have now intercepted the probe and are using it as a coffee table. Any data returned are the result of spilled coffee, or alien equivalent thereof. :-)

  • "What do they hope to gain?" you ask.....
    A lot!
    It may seem like an insignificant thing to do, reestablish contact with a 35-year-old probe that is millions of miles away. You have to look at the big picture in the future when people are living and traveling away from this planet the research may prove (will definitely prove) to be invaluable.
    Also I wonder what the ping time would be for the pioneer 10?
