Missile Test Creates Huge Expanding Halo of Light Over Hawaii

Posted by samzenpus on from the looks-like-progress dept.

The Bad Astronomer writes "A Minuteman III missile launch from California early Wednesday morning created a weird, expanding halo of light seen from the CFHT observatory on Hawaii's Mauna Kea. The third stage of the missile has ports that open and dump fuel into the near-vacuum. This cloud expands rapidly as a spherical shell, shock-exciting the air molecules and causing them to glow, creating the bizarre effect."

      This was not a nuke. The missle was unarmed. It was a flight and systems test. One thing the article fails to point out is the the fuel in the third stage is hypergolic. It is two parts, monomethylhydrazine and nitrogen tetroxide, which ignite upon contact. SO!! One can only assume that upon a fuel dump, there would be ignition which, it seems to me, would fully and totally explain this expanding cloud of glow.

      Yes, that's the one. While it originated at Vandenberg, technically it wasn't launched from Vandenberg. It was launched from a modified L-1011 in mid-flight.

      SpaceX has its first west coast launch scheduled for July 9, launching a Canadian communications and research satellite from Vandenberg. That's been pushed back from April, then June, to its current July 9 date. Word is it may slip again to July 20. Elon Musk has said they're going to try to execute a powered soft landing of the first stage into the ocean so they can recover it and reuse it.

      After that is an NRO spy satellite currently scheduled to go up on Aug 28 on a Delta IV Heavy, which with the retirement of the Shuttles is now the biggest rocket in service in the U.S.

    You answered your own question. These missiles have been active for 40 years. They need to be tested to make sure they work. They go out to the missile fields and they pick a missile at random, pull it out of the silo, remove the warheads, fly it over to Vandy, install instrumentation and dummy warheads, take the crew from the field it was in and fire it down range, making sure everything works right still.

    This is also one of the very few times that a crew actually gets to launch a live missile, so its an exciting exercise for them as well, so much so that the exercises are called "Glory Trip".

    Anyway, pretty much everyone tests their stockpile of ICBMs and SLBMs to make sure they are working, otherwise deterrence starts to lose some of its credibility.

    Furthermore, and a little dark, but think about how amazing it'd look to be in north central Canada if WW3 breaks out on a clear night and you have hundreds of these missiles going down range... The end of the world would be somewhat pretty.

      Yeah, I caught that as well.

      Third stage, at least, has dump ports. At precise time according to flight plan, charges open vents in side of can, venting combustion gases and this abruptly ends continued boost. (Yah, I know that first stage is called boost phase, so sue me.)

      Guy who thought it was fuel being dumped maybe thinks solid-fuel rockets burn from one end to the other. Obviously he doesn't understand just what solid fuel means. He was certainly too lazy to look it up (that or had a five minute deadline and little prior knowledge of rockets).

      The Minuteman III has ports in the third stage that can be blown to vent the motor case, slowing or stopping the burning of the grain, and essentially shutting down[1] the motor. It's this vented gas ("dumped fuel") that produced the halo. When the ports are blown the motor decelerates rapidly, so they use this to their advantage by simultaneously separating the bus, thus ensuring the third stage will be clear as the bus maneuvers to start releasing warheads.

      This used to be a fairly common method of controlling the final velocity of solid fueled ballistic missiles. It was used by; MM-I, MM-II, MM-II, Peacekeeper, Polaris A-1 and A-2, Poseidon C-3, ASROC, and SUBROC. (There may be more, those are just the ones I know about.) Trident -I and -II use GEMS (Generalized Energy Management Steering) to adjust the missiles trajectory so that at burnout it's at the desired final velocity.

      [1] Yes Virginia, you can (contrary to what "everyone knows") essentially shut down a solid rocket motor - but it's a very violent event. A tandem staged missile can just leave the decelerating stage in it's wake, but the Shuttle cannot. Whether they simply blew the connections to the ET (which also exposes the orbiter to the sandblast of the SRB's exhaust), or blew ports in the SRB casing, the transient forces would turn the stack into confetti. The orbiter would be tossed into the airstream and be torn apart. (This is what happened to Challenger when the ET broke up after the RH SRB came loose and crashed into it. The subsequent explosion, while very impressive to the naked eye, was actually very low pressure and low energy and played very little part in destroying the orbiter.) The looked into using an Orbiter mounted solid fueled escape motor to power away from the stack under thrust and control, but it turned out to be way too heavy. (Even if they traded fuel in the ET for the solid fuel in the escape motor and used it for part of the final kick into orbit.)

      Unlike Cape Canaveral which launches into an equatorial orbit to the east, Vandenberg launches into polar orbits to the south, and tests to the Marshall Islands to the west. That means the vapor trail is in prime position to be backlit by sunlight in the upper atmosphere just after sunset, making for very dramatic sights and photos as you describe. If the timing is right, on a clear day it's visible from most of Southern California. A friend of mine has a spectacular photo he took of such a launch from Joshua Tree, which is about 250 miles away.
