Sunita Williams 3rd Space Mission Postponed: Sunita Williams' third space mission postponed

Worlddesk:
Sunita Williams 3rd Space Mission Called Off: Indian-born astronaut Sunita Williams' third space mission has been postponed for the time being.  Butch Wilmore was to accompany him on this trip.  ULA's Atlas V rocket was scheduled to be launched from Cape Canaveral Space Force Station in Florida at 8.4 am Indian time on Tuesday.  The mission has reportedly been postponed for the time being due to a last-minute problem with the rocket's oxygen relief valve.
The objective of the 10-day mission is to get humans to the International Space Station and back.  If the mission is successful in the future, it will be considered a big step in the field of space.  If the mission is successful, the United States will have two spacecraft to send astronauts into space for the first time in history.  Right now, the US has only the Dragon spacecraft from Alan Musk's company SpaceX.
