It is NASA's most ambitious Mars mission yet, totaling around $3 billion (roughly Rs. 22,647 crores).
The launch of NASA's next Mars rover mission has been delayed to no earlier than July 30 because of a launch vehicle processing issue, the latest in a series of slips that have now used up almost half of the available launch opportunities for the mission.
However, NASA noted the launch window could still be extended further into August. The space agency issued a brief statement blaming this delay on issues with the launch vehicle and says it's possible the launch could be pushed back even further. A liquid oxygen sensor line produced "off-nominal data" during a practice session, and the mission team will need extra time to evaluate what happened. Two weeks later, the agency said "a contamination concern in the ground support lines" in a payload processing facility would push the launch back two additional days, to July 22.
NASA initially said the launch must take place no later than August 15, but more recently suggested the window may be extended.
This problem occurred during a test run on 22 July.
