Explorer 1

Wow! It’s been 60 years. I remember staying up late on a Friday night to watch Shock Theater on WSIX-TV (the monster movie that night was The Invisible Man) and seeing a bulletin about the Army’s launch of Explorer 1 during the newscast just before the station signed off for the night.

And now there is hardware that I designed flying on NASA x-ray astronomy missions.

Whoda thunk it?

A Profile in Cluelessness

I found this exchange on the Twitterz. Karoli has lived in Ventura County, California, for several years. It’s just down the coast from Vandenberg Air Force Base, the DoD’s main west coast launch facility. The sight of rockets rising from Vandenberg has been quite common in that part of Southern California for decades. She must not look up at the sky very much.

When I lived in Ventura County back in the early ’80s, I occasionally saw the trails from the test launches for the MX missile program during my evening commute from the San Fernando Valley to Thousand Oaks.

Yesterday’s launch was a SpaceX vehicle carrying multiple satellites to Low Earth Orbit.

Almost all launches out of Vandenberg go due South into polar orbit. Polar orbit launches go from California because the next major landfall is Antarctica, whereas a polar launch from Florida would go over populated areas immediately. Only the Kodiak, Alaska, facility has a longer path over water.

Quote of the Day

If you take a bale of hay and tie it to the tail of a mule and then strike a match and set the bale of hay on fire, and if you then compare the energy expended shortly thereafter by the mule with the energy expended by yourself in the striking of the match, you will understand the concept of amplification.
