Here's an example of the use of "X" by the Army ... It's a 1958 #JPL documentary about the launch of Explorer 1, the first U.S. satellite, on January 31, 1958. The satellite was placed on a modified Army Redstone called a Jupiter-C or Juno 1, but it's really a Redstone. Anyway,you'll see X used throughout the documentary. #Space #NASA
@WordsmithFL I love anything space related. Keep sharing that trivia!
@JK It's what I do when I'm not babbling about politics. π I live seven miles south of Kennedy Space Center. SpaceX woke me up this morning at 4:35 AM EST with a night launch.
@WordsmithFL You are living my dream! That is so cool.
@JK Yeah, well, not so glamorous when it's the middle of the night and you're standing out amongst the mosquitoes waiting for a launch only to have it cancelled because some schmuck sailed his boat into the no-sail zone. π€¬
But it has its perks. π
@WordsmithFL i have had 5 shots so far. I know, I am a pin cushion and monitored by Melinda Gates, she got access to my highly classified chip in the divorce settlement. I only had a reaction to the first shot and it way mainly injection site soreness. All my boosters, including the bivalent, have been smooth sailing with no noticeable reaction.
@realDineaux Glad to hear. Each shot kicked my tail, so I'm expecting a down day, but we'll see.
My wife had one J&J. It never affected her.
@WordsmithFL Mine were all Moderna.
@realDineaux So are mine.
Ever wonder what the "T" stands for when we space biz people say, "T minus 60 seconds ..."?
The T stands for Time!
It goes back to the 1950s, when both the Air Force and the Army were at Cape Canaveral firing test missiles. The USAF used T for Time, but the Army used X! Wernher von Braun was with the Army at that time; perhaps the X went back to the V-2 tests at Peenemunde.
Eventually the USAF took over missile tests, von Braun went to NASA, and the X went away. We were left with T. π
