DARPA Loses Contact With Hypersonic Glider

x_IamSpartacus_x writes "DARPA says contact with its experimental hypersonic glider was lost after launch from Vandenberg Air Force Base on the central California coast. The agency says in Twitter postings that its unmanned Falcon Hypersonic Technology Vehicle-2 was launched Thursday atop a rocket, successfully separated from the booster and entered the mission's glide phase. The agency says telemetry was subsequently lost, but released no details."

      Eh, it's not a lot of speed. Accounting for doppler shift at higher frequencies than FM band (around 2M the problem starts, but anything in VHF or above is going to get wide-band distortion) would require computer equipment. Actually controlling the plane? Zilog Z80 and a hard real-time microkernel OS. Think like Minix, then you strip out most of the useless crap, add a few small bits of specialized crap, and then add all your control programs to run under that. This is not stock Minix or QNX off the shelf; it's as few lines of code as you can get, to run a stripped down and specialized hardware set, with known and easily organized data storage. Any logging happens in separate hardware, and any sensor data being pushed off goes out an I/O port with no bidirectional communication because, frankly, nobody cares; we're too busy flying a plane to deal with this foolishness, if the logging hardware fails the flight computer doesn't care.

      The Huygens mission to Titan would have been essentially lost if it weren't for one guy (Popken IIRC) who had a hunch that the Doppler shift wasn't correctly set up for receiver testing, and has done additional testing on the system while it was still enroute with Cassini to Saturn.

      The Huygens telemetry receiver was based on a design that had operated successfully on several earlier space missions. That receiver was able to cope with a Doppler shift at data rates of up to 2 kilobits per second (Kb/s). The data rate between Huygens and Cassini, however, was 8 kb/s—four times faster.

      Due to an implementation error, a scaling parameter in the Huygens receiver’s embedded software was not adjusted to accommodate the higher data rate. As a result, the bandwidth of the receiver’s bit synchronizer was too narrow to compensate for the Doppler shift of the data stream frequency.

      (source).

      What about engineers messing up units of measure, resulting in a loss of $300M mission:

      The MCO MIB has determined that the root cause for the loss of the MCO spacecraft was the failure to use metric units in the coding of a ground software file, “Small Forces,” used in trajectory models. Specifically, thruster performance data in English units instead of metric units was used in the software application code titled SM_FORCES (small forces). The output from the SM_FORCES application code as required by a MSOP Project Software Interface Specification (SIS) was to be in metric units of Newtonseconds (N-s). Instead, the data was reported in English units of pound-seconds (lbf-s). The Angular Momentum Desaturation (AMD) file contained the output data from the SM_FORCES software. The SIS, which was not followed, defines both the format and units of the AMD file generated by ground-based computers. Subsequent processing of the data from AMD file by the navigation software algorithm therefore, underestimated the effect on the spacecraft trajectory by a factor of 4.45, which is the required conversion factor from force in pounds to Newtons. An erroneous trajectory was computed using this incorrect data.

      if all the aiming is done in the boost phase then you're probably aiming at something the size of a city, while this thing could hit a city block or maybe a house.

      Well, in theory, we have exceedingly accurate ICBMs.

      But you mentioned something important: Moving targets. Part of the problem with an ICBM is that it's good at hitting military installations which don't move around very much. But suppose you have a mobile launcher? Something like this could conceivably be launched and have it's course corrected.

      But even ignoring that for a moment, I see nothing but good things coming from this research and the money spent thereupon. If they can figure it out for a missile (with government assistance), perhaps they can use this money to develop actual human transportation systems.

    It looks like it's a weapons delivery system capable of avoiding terminal ballistic missile defenses. A MARV (MAneuverable Reentry Vehicle).

    I thought we (the U.S.) were the only ones with a (semi)-robust missile defense system (well I guess the Isrealis also). I guess DARPA's just planning ahead for the day when the Chinese decide to redress the strategic balance by spending their Trillions on a good BMD. Also I'm thinking it must be so expensive that the only kind of warhead that's worth placing on board is nuclear. But then again maybe there are VERY specific soft targets which you absolutely positively have to kill in an hour (because that's all you know they'll be in that location for). Then a "conventional" warhead could do (or at 13,000MPH just a bunch of tungsten rods "Rods from God" would do. Think of it as an intercontinental sniper rifle with bullets that can swerve around defenses. Good for "decapitating" an enemy, (I guess a lot of threats we face would go away if we could take out just the top few people/person: are you listening Kim Jong-Il? Qaddafi? S&P ratings board?).

    Or maybe (as another poster mentioned on a previous slashdot forum), it's a (Chinese) carrier killer. In that case, the speed and maneuverability would be needed to avoid the presumably very intense defenses around the high value target. Unless we were willing to use nukes (which would open the door to nuclear retaliatory attacks) this would be the only way to take out such a target. That's assuming that our hunter killer subs couldn't get through their escorts and ASW.

    I was kinda hoping DARPA was working on a (much) faster version of the Wave-rider hypersonic aircraft. Oh well, guess even they can't beat the laws of physics (and our lack of a good propulsion system).

    Even "cooler" would be a laser that could be quickly lofted into space and would zap a target on the earth below. Unfortunately, "Real Genius" notwithstanding we don't have any lasers compact enough to be launched in anything short of a Saturn V (I don't think Dr. Teller's nuke pumped X-Ray laser was ever shown to work). That pesky outer space treaty prohibits us from placing weapons in space so we can't just have laser satellites floating around picking off people we don't like I guess.
