    Yeah, I know.

    It was a joke...
    Example probe was only 5 676 317 040 000 000 kilometers away from Antares at 2005-12-20 21:12:54 UTC.

    Don't worry, I'm sure this thread will still be active in 10 years time, I promise I'll keep an eye on it.

    Still, I don't think we can really call them interstellar probes: they will be space junk long before they reach the stars. I think that to be considered an interstellar probe, the probe has got to do more than have escape velocity from the Solar System, but actually be planned to be functional when it does reach the stars.

    So, probes like the Voyagers that are still providing scientific data about space at the boundary of the Solar System don't count? IMO, both voyagers at a minimum deserve the title.

    New Horizons had a page to itself in the Metro today; a free tabloid you read on the London Underground. This is of absolutely no significance except that once a topic ends up in the Metro it's almost certainly mainstream.

    Now watch as my beautiful inference gets shot down.
    Even though no official ephemerides for the probe has been released at this time, since only one possible orbit exists for launch on January 17, 2006 and Pluto arrival on July 14, 2015. So I did some calculations and simulations myself. New Horizons will travel really faster than I have thought before. The probe will make its flyby of Pluto at a speed of 13.78 kilometers per second, and around May 6, 2026, it will be farther away from Pluto than it was on December 17, 2005. The Jupiter gravitation slingshot will be on February 28, 2007.

    I think its perfectly fair to call the Voyagers "interstellar" probes. Especially since they're going to be giving us perfectly good data on the interstellar medium in a year or two.

    Its a hairsplit, but even though they'll never reach another star operational, they will be operational when they leave the Solar System.

    "Its a hairsplit, but even though they'll never reach another star operational, they will be operational when they leave the Solar System."

    As an extra hairsplit.... it depends on what you consider to be the edge of the solar system... the heliospause or the Oort cloud!

    Cheers

    I'd loveto get into that debate,but I'm afraid the KBO/Planet debaters have the duelling sabers all tied up at the moment. :P

    Good call, though

    With a bit of luck that distance will be drastically reduced when the New Horizons probe gets into space in a few weeks time!!!

    Not exactly. Actually, the reduced rate might be much slower in space for the first few months. Since the spacecraft will not be launched toward Pluto, but opposite. I've a gravitation simulation for this scene.

    Edit: You are right. I've done some calculations and New Horizons's range-rate with respect to Pluto will be about 23.696 kilometers per second on January 21 after launch, while the Earth will be 16.264 kilometers per second.

    I guess they really did put that disk with names on it, on the spacecraft. I was #400.

    Ms. Emily reports:

    I'll just make this an "all New Horizons" morning. The latest Expendable Launch Vehicle Status Report from Kennedy Space Center has some good news for New Horizons:

    The borescope inspection of the Atlas V RP-1 propellant tank was successfully completed this week, and no defects were observed. The results of the inspection serve to increase confidence in launch success, but further testing and modeling of the vehicle continues in order to provide confidence in proceeding to launch.

    This is important news because problems were found in a different Atlas V late last year that prompted the inspection of New Horizons' launch vehicle. The fact that "no defects were observed" removes one more hurdle before New Horizons' launch.
    Everything I need to know I learned through Googling.
