Launch/landing updates

It’s been a while since I’ve posted; work’s been crazy busy!  So I’ll quick catch you up with some of what’s gone up and down since I last posted:

On September 17, the latest Dragon capsule (CRS-12) returned from the ISS with a two tons of research material and hardware on board, including a population of laboratory mice sent into space to study effect on eyesight and movement.

On September 21, a Soyuz rocket from Plesetsk Cosmodrome placed the latest element of the GLONASS M navigation constellation into orbit.

On September 23, an Atlas V out of Vandenburg Air Force Base carried the classified NROL-42 into orbit for the National Reconnaissance Office.

Obviously, they won’t tell us much about the payload, but the mission patch and the launch site both suggest a polar orbiting spacecraft.  The size of the fairing and quantity of boosters both suggest a very big spacecraft, which is fairly typical for spy satellites.  It is believed to be a signals intelligence spacecraft, which means its job will likely be to intercept communications.  Maybe.  😉

Lastly, the Tianzhou 1 spacecraft returned to Earth in pieces last Friday.  It was supposed to; it was an experimental robotic resupply and refueling spacecraft similar in function to Progress, which also undergoes a destructive reentry at the end of its mission.  Tianzhou 1 completed a successful mission docking with the uninhabited Tiangong 2 space station, transferring propellant, and then later undocking and safely disposing of itself.  Tiangong 2 is not expected to host any more human occupants, but remains in orbit as a procedures testbed for ground controllers.  It is not clear when the next space station will fly; China intends to greatly increase the size and functionality of their stations, but they have had a major setback with the failure of the last Long March 5 rocket.  This is the heaviest rocket they’ve built to date, and is intended to place the major elements of their new modular space station in orbit, but with a 50/50 operational record after two flights, some more work is needed before it can carry such valuable cargo.
