Very sorry to hear of the death of @AstroMCollins today. Mike Collins (1930-2021) was the pilot of Gemini 10 and the command module pilot of Apollo 11.
@AstroMCollins While his crewmates were on the surface and he orbited above the farside Collins became the first human to have an entire world between him and all other humans.
Collins wrote the first really good astronaut autobiography, Carrying the Fire (which you should read).
Collins was the director of the Smithsonian's awesome National Air and Space Museum (which you should visit) during the 1970s when it first opened to the public.
Collins was born in Rome (his dad was US military attaché there at the time) and so was the first person born in western Europe to fly in space.
Collins died Apr 28 of cancer. He was retired and living near Fort Myers, Florida.
Ten of the 24 humans who have flown in deep space remain with us: Aldrin, Anders, Borman, Duke, Haise, Lovell, Mattingly, Schmitt, Scott, and Stafford
Collins was selected as part of NASA Group 3, in Oct 1963. Of the 14 Group 3 astros, 4 landed on the Moon and 3 others flew in deep space. Four died in training accidents without making a spaceflight. Aldrin, Anders, Cunningham, Schweickart and Scott are still alive.

Pleaides Neo 3 separation confirmed, congrats to @Arianespace and Airbus. Two more burns at 0251 and 0327 UTC before the remaining payload separations at 0331-0332 UTC
@Arianespace NorSat-3 is an AIS (ship tracking) satellite for the Norsk Romsenter (Norwegian Space Centre) and is a 15 kg Nemo class satellite built by UTIAS-SFL (Toronto). It also carries an instrument to detect navigation radars.
@Arianespace AII-Bravo is a 6U cubesat payload for Aurora Insight (D.C.) to monitor the radio spectrum enviroment, built by AAC SpaceQuest
Some fun facts about space debris reentries:
(1) A breakup like the one over Seattle happens at about 60 km (~40 miles) up, far above where airplanes fly (more like 10 km).
(2) satellites (including space junk like this rocket stage) orbit the Earth at over 7.5 km/s (17000 mph).
3) We could predict this rocket stage would reenter today. But as of yesterday the TIME at which it would reenter was still uncertain by 5 hours.
The Fregat stage should now have made its circularization burn and the first 4 satellite separations should happen soon
The first 4 sats released were OneWeb 0108, 0174, 0177, 0178. The second four satellites have now been released: 0155, 0163, 0166, 0171.
Satellites 0112, 0115, 0116 and 0158 should have been released at 0444 UTC, while I was distracted by North Korean missile geolocation. Satellites 0151, 0159, 0172 and 0173 will pop out at 0503 UTC, about 10 minutes from now
Updated sumary: the J-SSOD-M2 deployer flew to ISS on NG-15, taken to the Kibo module and moved outside with the JEM-RMS robot arm. At 0830 UTC Mar 22 it ejected its payload, the လောကနတ်-၁ (Lawkanat-1) microsat which is a joint project of Hokkaido U and MAEU (Meiktila, Myanmar)
A Reuters story by @kellyJapan noted the controversy over the sat. The report today by @heinkoLwin confirms the deployment and says that Lawkanat-2 is scheduled for Sep 2023.
@kellyJapan@heinkoLwin The announcement republished by Lwin says " Under the terms of the agreement, the Earth observation satellite is intended for the following non-military peaceful uses: They are: (1) Agriculture; (2) Forests; (3) Rural areas; Urban change; (4) Oceanography;

Electron 19's Stage 2 has been cataloged as 47965, 2021-023A, in a 297 x 557 km x 45.0 deg orbit.
The payloads on Electron 19 are:
A Black Sky Global satellite (possibly Global-5?), about 55 kg, separated at 0019 UTC Mar 23;
RAAF's M2 A and B, two 6U sats deployed at 2322 UTC Mar 22; Fleet's Centauri 3, a 6U built by Tyvak, deployed 2323 UTC; (1/2)...
Care Weather's Veery Hatchling, a 1U deployed at 2324 UTC; one of the US Army SMDC's Gunsmoke-J series (J2?) deployed at 2324 UTC; and Myriota's Myriota 7, deployed at 2325 UTC.
