Following this naming tradition, the crew-1 crew members also chose a name for the spacecraft. NASA astronaut Michael Hopkins announced the name of the Dragon spacecraft carrying out crew-1 mission - toughness at a NASA news conference on September 29, local time.
Hopkins explained that the name reflects the challenges facing this year. Resilience is not only for the astronauts involved in this mission, as well as the SpaceX and NASA teams, but also for the United States and the world.
If you look at the definition of resilience, it means to perform well in the face of stress or overcome adversity. I think we all agree that 2020 will definitely be a challenging year. Hopkins thinks tenacity is a good fit for the Dragon ship, and he hopes the name will inspire everyone.
The day before the news conference, NASA issued a statement saying it plans to launch the dragons first commercial manned mission crew-1 at 2:40 a.m. EST on October 31. NASA astronauts Michael Hopkins, Victor Glover, Shannon Walker and Japanese astronaut Soichi Noguchi will fly to the international space station on the SpaceX manned dragon spacecraft at the Kennedy Space Center in Florida.

NASA and SpaceX also incorporated the experience learned from the first manned test mission of the manned dragon spacecraft into the spacecraft design, and made some adjustments to the hardware and program of crew-1 mission.
One of the improvements involves the heat shield of the spacecraft. At 14:48 on August 2, US Eastern time, the endeavor dragon spacecraft safely returned to earth and landed in the Gulf of Mexico near Florida. When SpaceX engineers inspected the capsule returning to earth, they found more severe wear than expected in several specific areas of the heat shield.
However, Hans koenigsmann, vice president of SpaceX manufacturing and flight reliability, said the wear was limited to a very small area on the heat shield and did not put the astronauts involved in the first manned test flight at risk.
The problem may be related to the airflow around the bolts that connect the capsule to the main part of the spacecraft. Hanskoenigsmann said the problem was also relatively easy to repair, as long as more corrosion resistant materials were used in the area around the bolts.
Another improvement is to adjust the pressure sensor that triggers the parachute to open during the splash down process. During its return to earth in August this year, the height of the parachute was slightly lower than expected. The adjustment of the sensors will ensure that crew-1 astronauts can open their parachutes earlier and higher when they return.
NASA and SpaceX also contacted the U.S. Coast Guard and asked them to set up a 16 kilometer cordon around the planned splash area when the astronauts were scheduled to arrive. Because in August this year, more than 10 private ships gathered around the spaceship, some very close to the spacecraft.
