GLOMR (Global Low Orbiting Message Relay)
DARPA (Defense Advanced Research Projects Agency) satellites designed to
demonstrate the ability to read out, store, and forward data from remote
ground-based sensors. GLOMR was first scheduled for deployment from a modified
Get-Away Special container on Space
Shuttle mission STS-51B, but failed to eject because of a battery problem.
It was reflown and deployed successfully from STS-61A, and reentered after
GLOMR II, also known as USA 55 and SECS (Special Experimental Communications
System), was roughly the size of basketball and had greater data storage,
more redundancy, and more space-qualified hardware than its predecessor.
