And a Falcon 9 will launch the second Crew Dragon mission, sending four astronauts to the International Space Station on late September TBA, in the afternoon EDT. The launch time gets 22-26 minutes earlier each day.
Media accreditation now is open for NASA’s SpaceX Crew-1 mission to the International Space Station – the first operational flight of the SpaceX Crew Dragon spacecraft on a Falcon 9 rocket after certification by NASA for regular flights to the space station.The launch is targeted for no earlier than late-September, following a successful return from the space station and evaluation of NASA’s SpaceX Demo-2 test flight with NASA astronauts Robert Behnken and Douglas Hurley.Crew Dragon commander Michael Hopkins, pilot Victor Glover, and mission specialist Shannon Walker – all of NASA – along with Japan Aerospace Exploration Agency (JAXA) mission specialist Soichi Noguchi will launch on the Crew-1 mission from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
NASA and SpaceX are targeting 7:34 p.m. EDT Saturday, Aug. 1, for undocking of the Dragon “Endeavour” spacecraft from the space station and 2:42 p.m. Sunday, Aug. 2, for splashdown, which will be the first return of a commercially built and operated American spacecraft carrying astronauts from the space station.Coverage on NASA TV and the agency’s website will begin at 9:10 a.m., Aug. 1, with a short farewell ceremony on station and resume at 5:15 p.m., with departure preparations through splashdown and recovery at one of seven targeted water landing zones in the Atlantic Ocean or Gulf of Mexico off the coast of Florida.
Progress MS-14 will correct the ISS orbitIn order to form ballistic conditions before the launch of the Soyuz MS-17 manned transport vehicle, the orbit of the International Space Station is scheduled to be corrected on July 29, 2020.According to preliminary data from the ballistic and navigation support service of the TsNIIMash Flight Control Center (part of the Roscosmos State Corporation), the engines of the Progress MS-14 spacecraft will be turned on at 16:42 Moscow time and will operate for 336.3 seconds. After that, the height of the station's orbit will increase by 1,100 meters and will be about 419.1 km above the Earth.The launch of the Soyuz-2.1a carrier rocket with the Soyuz MS-17 manned spacecraft is scheduled for October 2020 from site No. 31 of the Baikonur cosmodrome. The crew of the Soyuz MS-17 spacecraft included Roskosmos cosmonauts Sergei Ryzhikov and Sergei Kud-Sverchkov, as well as NASA astronaut Kathleen Rubins.
ISS Orbit CorrectionToday, July 29, 2020, the orbit of the International Space Station was corrected. The engines of the Progress MS-14 cargo vehicle, with the help of which the orbit correction was carried out, were turned on at 16:57 Moscow time for 336 seconds, as a result the ISS received an impulse of 0.65 m / s. After the corrective maneuver, the average altitude of the ISS orbit increased by 1.1 km.According to the data of the ballistic and navigation support service of the Flight Control Center of TsNIIMash (part of the Roscosmos State Corporation), the station's orbit parameters after the correction were: Orbital period: 92.87 min; orbital inclination: 51.66 degrees; minimum height above the Earth's surface: 417.5 km; maximum height above the Earth's surface: 436.2 km.This operation was carried out in order to form ballistic conditions before the launch of the Soyuz MS-17 manned spacecraft.
The International Space Station also completed the first of three orbital reboosts to get ready for the next crew mission in October....The docked Progress 75 resupply ship fired its engines this morning for five-and-a-half minutes slightly lifting the station’s orbit. There will be two more station reboosts before the Soyuz MS-17 crew ship launches in October with NASA astronaut Kate Rubins and cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov. They will dock to the Rassvet module a few hours after launch to begin a six-month mission as the Expedition 64 crew.
The SpaceX Crew Dragon “Endeavour” spacecraft with NASA astronauts Robert Behnken and Douglas Hurley inside undocked from the forward end of the International Space Station’s Harmony module at 7:35 p.m. EDT to complete a two-month mission.
Here’s the timeline for return activities (all times Eastern): 1:51 p.m. – Crew Dragon performs claw separation. The claw is located on Crew Dragon’s trunk, connecting thermal control, power, and avionics system components located on the trunk to the capsule. 1:51 p.m. – Trunk separation 1:56 p.m. – Deorbit burn begins 2:08 p.m. – Deorbit burn complete 2:11 p.m. – Nosecone deploys 2:32 p.m. – Crew Dragon maneuvers to attitude for re-entry 2:44 p.m. – Drogue parachutes deployat about 18,000 feet in altitude while Crew Dragon is moving approximately 350 miles per hour. 2:45 p.m. – Main parachutes deployat about 6,000 feet in altitude while Crew Dragon is moving approximately 119 miles per hour. 2:48 p.m. – Splashdown
