Last week, NASA announced that SpaceX’s Demo-2 commercial manned flight would bring astronauts Doug Hurley and Bob Behnken back to Earth, landing in the ocean near Florida at one of the seven planned landing locations ( off Pensacola, Tampa, Tallahassee, Panama City, Cape Canaveral, Daytona or Jacksonville As expected, the flight will land at 1:42 p.m. on August 3, if the weather is favorable and technical systems operate. normal.
The return flight time to Earth is 6 hours and 30 minutes, depending on the spacecraft disassembly process and the chosen landing area. Currently, NASA and SpaceX plan to separate the Crew Dragon from the International Space Station (ISS) at 6:34 am on August 1, Hanoi time.
The flight landing on the Demo-2 sea will become a historic landmark. The last time astronauts landed at sea was on 24/7/1975 to complete the Apollo – Soyuz test project between the US and the Soviet Union. Demo-2 also completed its first commercially manned-ship test mission, making NASA ready for recurring flights with SpaceX. The next flight with a crew of four will take off in September 2020.
The exact landing location was announced only two days before the flight. NASA will reconfirm the location 6 hours and 2.5 hours before proceeding to disassemble the spacecraft. If the conditions at the landing site are unfavorable, disassembly continues. NASA and SpaceX will continue to watch as astronauts fly closer to Earth, as weather conditions can change rapidly and authorities still prioritize the location of the landing if possible. In the event that conditions remain unpredictable, the crew can choose to stay aboard the Crew Dragon Endeavor for 24 to 48 hours and then attempt to land again.
Landing depends on many factors such as wind power (no more than 4.5 m / sec), wave slope at sea no greater than 7 degrees, no rain and lightning within 16 km, helicopter availability welcome astronauts, the vibration of the ship does not exceed 4 degrees, the visibility is from 0.8 km or more.
