You will need to wait longer to see the perseverance roamer begin his journey to Mars. NASA and the Joint Launch Alliance have postponed the “Mars 2020” mission on July 22 until July 30. NASA said that the handling of the launch vehicle should be blamed. The liquid oxygen sensor production line produced “nominal data” during an exercise, and the task team would need additional time to evaluate what happened.
If at least the 30th fails to function properly, the agent has more time to start. NASA originally planned to extend it to August 5, but analysts have extended the window to August 15, and will determine whether it can be extended again. The rover is expected to land on the Mars Jezero crater on February 18, 2021.
