Punktlandung der Startstufe auf der JRTI nach 8 Minuten. Das wird nie alt.
Man muß sich das mal gepflegt ausmalen: Da startet so ein 70 m hoher Schornstein mit einem Gewicht von 540 Tonnen, erreicht 9fache Schallgeschwindigkeit & beginnt aus 116 km Höhe zu fallen. Zwei Abbremsungen - 1 x für 30 Sekunden mit 3 der 9 Merlin-Triebwerke in 45 km Höhe, eine zweite mit einem Triebwerk in gut 3 km Höhe für 15 Sekunden - und dann setzt das Ding butterweich & absolut punktgenau im Zentrum der Zielscheibe im 280 Kilometern Entfernung vom Schießplatz auf. Der 5. Start dieses Boosters war erst vor drei Wochen.
23:46. In gut 5 Minuten überfliegt die Zweitstufe über Mitteleuropa, in einer Linie über Amsterdam, Frankfurt am Main und weiter Richtung München. 23:53. T bei 26 Minuten. Über dem Schwarzen Meer. 23:59. T +32 Minuten. Über Mekka.

Zitat "Роскосмос" принял решение о дате окончания работы на МКС
МОСКВА, 30 апр — РИА Новости. Решение по дате окончания работы России на Международной космической станции (МКС) уже принято, но публично сообщать о нем "Роскосмос" не обязан, заявил гендиректор госкорпорации Дмитрий Рогозин. "Мы подготовили свои предложения, <...> они отправлены правительству и президенту. Решение принято уже. Мы не обязаны о нем говорить публично", — сказал он в эфире телеканала " Россия 24". Рогозин добавил, что Россия предупредит партнеров по МКС за год до окончания работы. По его словам, такой срок предусмотрен международными обязательствами.
Rogosin hat gestern auf dem Kanal "Rossija 24" erklärt, daß Roskosmos die Zusammenarbeit mit der ISS aufgrund der Sanktionen einstellen wird, die Entscheidung sei gefallen, das Datum stehe fest, es würde aber noch nicht bekanntgegeben. Und die bisherigen westlichen Partnerländer würden 12 Monate vor Ablauf in Kenntnis gesetzt.

Zitat SpaceX passes 2,500 satellites launched for Starlink internet network
SpaceX launched a Falcon 9 rocket Friday afternoon from California’s Central Coast with another batch 53 Starlink internet satellites, pushing the total number of spacecraft launched in the network above 2,500, including testbeds and prototypes already cycled out of the fleet.
The Falcon 9 lifted off at 3:07:50 p.m. PDT (6:07:50 p.m. EDT: 2207:50 GMT) Friday from Vandenberg Space Force Base, a military spaceport between Los Angeles and San Francisco.
The mission was the 19th Falcon 9 launch of the year, and the 45th SpaceX mission primarily dedicated to deploying satellites for the Starlink internet network.
The launch from Vandenberg raised the total number of Starlink satellites launched to more than 2,547 spacecraft. That number includes prototypes, failed satellites, and decommissioned spacecraft no longer in the constellation.
More than 2,200 Starlink satellites are currently in orbit and working, according to an analysis by Jonathan McDowell, an astrophysicist who tracks spaceflight activity. That’s about half of SpaceX’s planned first-generation network of 4,408 Starlink satellites.

Zitat A United Launch Alliance (ULA) Atlas V rocket will launch Boeing's Crew Space Transportation (CST)-100 Starliner spacecraft on its Orbital Flight Test-2 (OFT-2) to the International Space Station. OFT-2 is the second uncrewed flight of the Starliner that will demonstrate the spacecraft's human transportation capabilities. This test flight is the last major step before the Atlas V and Boeing's Starliner capsule take American astronauts to the International Space Station as part of NASA's Commercial Crew Program.
Launch Date and Time: Thursday, May 19, 2022 at 6:54 p.m. EDT (2254 UTC)
*** May 18 16:02 Rollout Preps
The undercarriage jacks have raised the Mobile Launch Platform (MLP) from the pedestals in the Vertical Integration Facility (VIF).
Technicians are completing the final few steps in the procedures to prepare for rollout, having switched systems from the VIF to portable elements used during the transfer that will cover one-third-of-a-mile distance. That included generator power, communication lines and transitioning the environmental control system (ECS) to the portable trailers connected to the MLP.
Zur Erinnerung: Beim Erstflug im Dezember 2019 ist es zu massiven Problemen mit der Steuerung gekommen; beim Start war der Treibstoffverbrauch so hoch, daß die Kapsel nicht mehr aus dem Parkorbit in 190 km Höhe an die ISS andocken konnte; außerdem ist es zu mehreren Ausfällen der Kommunikation gekommen. Ein Triebwerk ist ausgefallen; eins der drei Trägheitsnavigationssysteme ditto, und ein Ventil für die Stickstoffbetankung zur Lagekontrolle ebenfalls.

The United Launch Alliance Atlas V rocket is perched atop Cape Canaveral's Space Launch Complex-41 for Thursday's launch of Boeing's CST-100 Starliner on the second Orbital Flight Test (OFT-2) in support of NASA's Commercial Crew Program.
Zitat May 18 18:02
Thursday's precise liftoff time has been established for the Atlas V rocket to send Boeing's Starliner spacecraft on its journey to the International Space Station.
Based upon the latest tracking of the station's orbit, launch is targeted to occur at 6:54:47 p.m. EDT (2254:47 UTC) from Space Launch Complex-41 at the Cape Canaveral Space Force Station, Florida.
The launch opportunity is instantaneous, meaning there is only a moment in time available each day for liftoff to occur when the orbital plane of the space station passes over the pad.
At the time of launch, the station will be 262 miles (422 km) above the North Atlantic approaching Europe. Starliner will rendezvous and dock with the station about 24 hours after liftoff.
Zitat May 18 20:26 Atlas RP-1 Loading
Fueling of the Atlas V first stage is underway at Cape Canaveral's Space Launch Complex-41. The launch team is pumping 25,000 gallons of RP-1 fuel, a highly refined kerosene, into the rocket for Thursday's flight.
The room-temperature RP-1 fuel that will power the main engine during the initial phase of the Starliner launch. Fueling of the rocket with cryogenic liquid oxygen to the main stage and liquid hydrogen and liquid oxygen to Centaur occurs during tomorrow's countdown.

This is Atlas Launch Control at L-11 hours, 20 minutes (T-minus 6 hours, 20 minutes) and counting!
The countdown has been initiated for liftoff of the Atlas V rocket carrying the Starliner spacecraft on its Orbital Flight Test-2 (OFT-2).
Today's countdown lasts more than 11 hours from now through liftoff, which is longer than previous Atlas V flights.
There are two pre-planned, built-in holds scheduled in the count. The first is reserved prior to fueling at T-minus 2 hours and lasts 60 minutes.
The second is a long-duration, four-hour hold that will be inserted into the countdown after the completion of fueling operations at the T-minus 4 minute mark. That block of time allows the Blue Team to enter the launch pad with the rocket is in a quiescent state to perform all of the necessary work to prepare the Starliner crew module for flight. On future crewed missions, this will be the time in which the astronauts board the capsule and get strapped into their seats.

Zitat NASA shelves routine spacewalks for now due to leaky helmet
NASA is suspending all but the most urgent spacewalks after water was found in an astronaut's helmet following a March excursion, agency officials said on Tuesday (May 17).
NASA will perform an assessment of its extravehicular mobility unit (EMU) spacesuits after water was found in the helmet worn by European Space Agency (ESA) astronaut Matthias Maurer following a March 23 spacewalk, agency officials said.
This means that astronauts will not go outside and perform extravehicular activities (EVAs) unless there is a pressing need for repairs on the International Space Station. Given that the affected EMU won't return to Earth for analysis until July, non-urgent spacewalks will be off the table for several months at the least.
This is the second time spacewalks have been suspended due to unexpected water leakage, although the last time in July 2013 was far more serious.
During that 2013 incident, ESA astronaut Luca Parmitano experienced a severe water leak that ended up covering most of his face. His spacewalk with NASA's Chris Cassidy was cut short due to the water volume Parmitano was reporting, roughly an hour after starting the work. Parmitano emerged safely from the incident and without injury, however.
NASA suspended all spacewalks back then amid an investigation, which culminated in a December 2013 report that identified multiple factors, from the spacesuit's construction to NASA procedures, that could be amended to prevent future such issues. (For example, water had been reported before by spacewalking astronauts, and NASA determined that a halt and investigation should have happened before Parmitano's excursion.)
The mishap report identified the immediate technical cause for the 2013 incident as "inorganic materials causing blockage of the drum holes" in an EMU water separator. This, in turn, caused water to spill into a vent loop.
The incident in Maurer's spacesuit seems to be the most serious water problem faced since NASA implemented the 2014 fixes.
Maurer reported about 8 to 10 inches (20 to 25 centimeters) of water in a very thin layer, covering the helmet's inner surface. The suit sometimes does generate a bit of water, Weigel said during the Tuesday news conference, but "this was a bit beyond what our normal experience faces. It was specifically the quantity of water that got our attention."
We are now exactly three hours away from liftoff. Blue Team operations continue to progress smoothly at the pad while launch team members here at the Atlas Spaceflight Operations Center monitor the health and status of rocket systems.
Liftoff remains targeted for exactly 6:54:47 p.m. EDT (2254:47 UTC).

Zitat Starliner will reach a position about 82o feet (250 meters) from the station around 5:46 p.m. EDT (2146 GMT). At that time, Starliner should have established a communications link with the space station, allowing the astronauts inside the research complex to send commands to the approaching capsule.
Zitat Kenneth Chang@kchangnyt Still no update since last night about Boeing's Starliner spacecraft supposedly en route to the International Space Station. According to the timeline Boeing distributed before launch, a go/no-go decision for approach to the station should occur ~2:30 p.m. ET. 7:45 PM · May 20, 2022·Twitter Web App
Hopefully we'll find out what's been going on when NASA TV resumes coverage at 3 p.m.
Mission control in Houston just informed astronaut Bob Hines on the International Space that the ISS Mission Management Team polled "go" for rendezvous of the Starliner spacecraft with the station later today.
Engineers overnight analyzed the failure of two thrusters during the orbit insertion burn. The Starliner’s orbital maneuvering and attitude control, or OMAC, jets were used for the injection burn, and will be fired again for several rendezvous burns to fine-tune the craft’s approach to the International Space Station.
“We had two thrusters fail,” said Mark Nappi, Boeing’s Starliner program manager. “The first one had fired. It fired for a second and then it shut down. The flight control system did what it was supposed to and it turned it over to the second thruster. It fired for about 25 seconds and then it shut down.
“Again, the flight control system took over, did what it was supposed to, and and went to third thruster and we had a successful orbital insertion,” Nappi said.
The Starliner spacecraft remained on course to dock at the space station around 7:10 p.m. EDT (2310 GMT) Friday, but officials said engineers will analyze the thruster issue overnight before a management meeting Friday morning to decide on whether to proceed with the approach to the station.
Steve Stich, NASA’s commercial crew program manager, said the spacecraft has “plenty of redundancy” to complete the test flight without the failed thrusters. The thrusters that shut off during the orbit insertion burn are located in one of four doghouse-shaped propulsion pods on the Starliner service module.
Each “doghouse” has three aft-facing OMAC engines, for a total of 12. There are eight additional OMAC engines positioned in other areas of the spacecraft. Each OMAC thruster generates about 1,500 pounds of thrust, and are used in conjunction with lower-thrust reaction control system thrusters to maneuver the Starliner spacecraft in orbit.
The OMAC engines completed another orbit phasing burn Thursday night, and will be used again for approach maneuvers closer to the space station Friday. The capsule’s final approach will be controlled by the smaller reaction control system jets, then the OMAC engines will fire again at the end of the mission for the deorbit burn to set up the Starliner for re-entry and landing.
Despite the thruster problem, NASA and Boeing officials were pleased with the start to the Starliner’s unpiloted demonstration mission, known as Orbital Flight Test-2. Officials also a sublimator, part of the Starliner’s cooling system, was “sluggish” during the launch, but its performance improved once the spacecraft arrived in space.
Astronaut Kjell Lindren on the International Space Station has sent a test command to turn on a docking light on the Starliner spacecraft. This demonstrates the command link between ISS and Starliner.

From the just-concluded post-docking briefing: Boeing says they’ve identified “three of so” potential causes for the OMAC thruster failures, but may not be able to reach a definitive root cause since the service module is not returned. May be different causes for each thruster.
Also, two smaller reaction control system thrusters failed today. Plenty of redundancy in the overall system, so no issues for undocking and landing.
Current plan is to remain docked to the station until at least May 25; that sets up a landing at White Sands, N.M., at 6:46 pm EDT that day, if weather permits.
