#OTD October 10, 1980 The Very Large Array radio telescope in New Mexico was dedicated. VLA is an "aperture synthesis" instrument using 27 antennas arranged in a "Y" pattern to gain the resolving power of an antenna 36 km in diameter.

#OTD October 4, 1957 First human-made satellite Sputnik launched from Kazakhstan by the Soviet Union. A metal 23in/58cm sphere, it orbited the earth for 3 weeks every 95 minutes, ~500mi/800km high at ~20Kmph/32Kkph. It's 1W signal on 20 & 40 MHz was easily heard by amateur radio.

The good news: Registration is now open for @shothisttech.bsky.social's virtual meeting!

The bad news: The conference schedule has not been posted.

The weird news: SHOT apparently owns a time machine...?

It and other tags like #histmed and #histtech go to a #HistSTM feed, although I think people may not be using tags and feeds as regularly these days?

#OTD September 24, 1852 The first powered Airship was demonstrated in a 3 hour flight from Paris to Élancourt, 17mi/27km. Henri Giffard installed a steam engine in the gondola of a 144ft/44m long coal-gas balloon semi-rigid airship and proved that controlled flight was possible.

Working on a #envhist #histtech research project is a real privilege. First, you discuss sources and methods with your team to reconstruct gas grid development, then you analyze sketches of the interior of the USSR's pipeline control center. And best of all, you even get paid for it!

Today at 1 PM, EDT (noon, CDT)!

Wait...is Artefacts being held the same week as SHOT?!

At least people could conceivably participate in both meeting since:
1) They won't overlap (Artefacts=M-W, SHOT=Th-Sun)
2) SHOT will be virtual

#OTD September 11, 1940 First 'remote computing' took place between a teletype terminal in New Hampshire communicating over phone lines with Bell Labs Complex Number Calculator in New York. Later called the Model I Relay Computer, it used telephone relays and groups of four bits. #histtech
