According to foreign media reports, so far, SpaceX’s Dragon demo-2 mission is a victory of NASA’s astronaut program. Astronauts Bob Behnken and Doug Hurley successfully launched and arrived at the international space station (ISS) at the end of May this year. Now, they are ready to return.
the re-entry process will undoubtedly be dramatic. “The manned dragon spacecraft will fly at an orbital speed of about 17500 mph (about 28175 km / h) before re-entry into the atmosphere. The maximum temperature on return is about 3500 degrees Fahrenheit (about 1927 degrees Celsius), “NASA said in a July 24 statement.
a SpaceX recovery and propagation ship will follow the manned dragon spacecraft, which will recover the spacecraft and parachutes from the water. Endeavor will be hoisted on board and medical teams will go to meet Behnken and Hurley.
if the manned dragon astronauts pass these final tests, SpaceX will be able to provide conventional, operational flights to the international space station from later this year. This will be the first time NASA has ended its dependence on Russian spacecraft since the space shuttle era.
