You certainly can't put an airplane (or a rocket/missile) in it.Not AE, but many of the early missiles tested at the Cape were "pilotless bombers" like Matador, Snark, and Navaho that were parked in Cape Canaveral hangars. Hangars were built for each program. Matador/Mace, for example, used Hangars A and B. Navaho occupied Hangars E and F. I'm guessing that Snark might have used Hangars C and D, but I'm not sure about that. By the time the ballistic missile teams arrived, they were building Hangars with letters beyond "H". Atlas, for example, was in Hangars H, J, K, and N, and it moved into Hangar F after North American's Navaho project folded. Titan was in T and U. Thor was in M. Minuteman was in I and N. Here's a USAF photo of a Snark in a Hangar. - Ed Kyle

edkyle99 - 11/10/2007 8:43 PMI just noticed this little tidbit, which I'll have to do some additional checking on to verify. According to my numbers, presented on the following pages, the next Delta 2 launch will be the 700th Thor-family launch since the first in 1957. http://geocities.com/launchreport/logsum.htmlhttp://geocities.com/launchreport/lvsum.htmlThis includes 24 N-1, N-2, and H-1 NASDA launches from Tanegashima, Japan, using licensed technology, but does not include two pre-launch accidents that destroyed Thor vehicles on their launch pads in the U.S.. At nearly 700 launch attempts, the Thor series has flown more often than any other large missile or launch vehicle series in the world except R-7/Semyorka, which just completed number 1,725.Alas, the Thor family, by most reports, will fly no more than 723 times. - Ed Kyle

I should have said that the Thor series was the second most-oft flown *orbital* launch vehicle. Missiles like Minuteman and R-14 (used for Kosmos 3/3M orbital launches) have flown more times than Thor, but have performed fewer orbital launches. - Ed Kyle

I can do some, good launch time for me Any help will be appreciated, however!

dawei - 17/10/2007 8:41 AMHow common is it to have this kind of signal problem? I know it has happened before. What has been the cause of this sort of problem in the past?
dawei - 17/10/2007 8:42 AMAOS timeline on ksc elv webpage is for second stage, is that correct? Anybody have an anticipated spacecraft AOS?
dawei - 17/10/2007 8:57 AM12 minutes to restart. 2nd stage has good quality date and all is "normal."
stockman - 17/10/2007 9:20 AMWhat is the typical or predicted decay rate of this orbit until burn up then? ie, how long will this stage be in orbit?
dawei - 17/10/2007 9:20 AMRIFCA has stopped commanding. KSC ELV page lists EOM as still being 127 minutes away. What else happens in the remaining time? Command receivers turned off? Anything else? Why wait another 127 minutes?

What has been the cause of this sort of problem in the past?It's happened throughout the entire history of both manned and unmanned spaceflight and rocket launches.As for the reasons... you name it, it's probably been the reason at one time or another.In this case, it appears from Marc's commentary that although Guam was recieving both the 2nd and 3rd stage telemetry signals, only the 2nd stage telemetry was getting thru to his station. To me it sounds like the Guam station had a signal processing problem that failed to insert the 3rd stage data into its transmission signal to Florida.

vt_hokie - 5/12/2007 11:13 PMNot sure if this is the best thread for this question, but I was wondering about the radiation environment for medium Earth orbit satellites like the GPS birds. Are they actually able to operate for years within the Van Allen belt?
Avron - 5/12/2007 11:59 PMGPS is at 20K km- outer Van Allen belt starts at 31k km and inner max is at 10K km.. So GPS is between the two belts
