The successes of this test flight were the first launch, successfully reaching apogee the skydive maneuver and the flip back to the vertical and landing, This was all achieved except the landing, due to a problem with the header tank. It took many attempts before vertical landings of boosters was achieved and now it is routine. Back in the early NASA days many rockets exploded during launch. For a private company space x has had huge achievements including providing NASA with the ability to transport astronauts the the international space station.

octave Posted December 10, 2020 Author Posted December 10, 2020 Just now, spacesailor said: AND, ! DISASTER . I,ve just watched the "spaceX "r rocket explode !, while landing. On the TV news. spacesailor Space I watched it live and have been following it closely for many years. The launch was a success. The reaching of apogee 12.5 km was I believe achieved. The skydive maneuver (a first) was achieved the return to the area of the landing pad was achieved. the flip to the vertical was achieved. The safe landing was not achieved. This rocket was not expected to survive this test. It will be interesting to see if sn9 which is complete and ready to go will correct the header tank problem. This is how science and technology advances 2

willedoo Posted December 14, 2020 Posted December 14, 2020 (edited) I like the terminology they use. SN8 experienced an RUD (rapid unscheduled disassembly). Sounds a lot better than 'crashed'. Edited December 14, 2020 by willedoo 1
nomadpete Posted December 14, 2020 Posted December 14, 2020 I rather think that Sn8 was rekitted upon landing. (Reduced to a kit of parts)
willedoo Posted December 20, 2020 Posted December 20, 2020 Russian Mission Control has asked the cosmonauts aboard the ISS to try to find a leak in their module. A previous crack was found and fixed in August, but a second leak is proving harder to find. It's starting to deplete the station's reserve O2 supplies. A Progress cargo ship is scheduled to go up in February with the option of taking up more oxygen. Another option considered is using U.S. craft to deliver it if needed. The old bird is wearing out. A lot of components were made with a certain shelf life in mind, but have spent many more years in service. It's due to retire in four years time, or possibly be pushed out to 2028. Due to it's age and condition, the Russians don't seem too interested in extending it longer than they have to. They're planning a Russian national station so are probably more inclined to concentrate finances and effort there. The Americans don't have much future interest there either, so we'll most likely see the end of it in the next few years.
Marty_d Posted December 20, 2020 Posted December 20, 2020 Google tells me it's been continuously occupied for 20 years and 47 days. Pretty bloody good for a collection of tin cans in an environment totally inimical to life. The closest equivalent would be a submarine, and none of them stay submerged for 20 years! 1 1
willedoo Posted December 20, 2020 Posted December 20, 2020 I think 15 years was the intended designed life span of a lot of Russian module components, so 20 years is on overtime.

willedoo Posted January 21, 2021 Posted January 21, 2021 Press reports are saying that NASA will be significantly winding back it's mission in Russia now that U.S. Astronauts have their own means of transport. There's talk of the majority of staff in NASA's Moscow office losing their jobs and a decrease in staff levels at the Cosmonaut Training Centre. Although they won't be closing the mission, they'll reduce staff numbers and stop renting cottages for the Astronauts and their families. It's also speculated that NASA will no longer have a permanent presence at the Institute of Medical and Biological Problems anymore and will only send its experts for separate consultations and meetings. The NASA mission in the Mission Control Center will remain almost unchanged.
willedoo Posted February 17, 2021 Posted February 17, 2021 Roscosmos has launched a Progress MS-16 robotic spacecraft to the ISS. One of it's jobs will be to deorbit the Russian docking module. Eventually in it's place will be the new science module and new docking module. 1
