The Launch Period
NASA and United Launch Alliance recently updated the mission’s launch period – the range of days the rocket can launch in order to reach Mars. It now spans from July 30 to Aug. 15.
The launch period opening changed from July 17 to 30 due to launch vehicle processing delays in preparation for spacecraft mate operations. Four days were also added to the previously designated Aug. 11 end of the launch period. NASA and United Launch Alliance Flight Teams were able to provide those extra days after final weights of both the spacecraft and launch vehicle became available, allowing them to more accurately calculate the propellant available to get Perseverance on its way.
A Mars-bound spacecraft is set to launch on Wednesday. Two more will follow by the end of the month.
NASA is planning to send its fifth rover to the red planet. China and the UAE have never been to Mars before.
One of the final pieces for the first test flight of NASA’s huge Space Launch System heavy-lift rocket recently arrived at the Kennedy Space Center, joining other elements already at the Florida spaceport awaiting shipment of the SLS core stage once it completes testing at a NASA facility in Mississippi.
The Launch Vehicle Stage Adapter, or LVSA for the first SLS test launch arrived at the Kennedy Space Center in Florida aboard NASA’s Pegasus barge July 29. Early the next day, hours before the liftoff of NASA’s Mars 2020 Perseverance rover from a launch pad a few miles away, ground crews transferred the LVSA from the Pegasus barge into the Vehicle Assembly Building at the Florida spaceport.
The LVSA is the second-to-last element of the first Space Launch System rocket to arrive at the Kennedy Space Center. The biggest piece of the rocket, known as the core stage, is expected to arrive at Kennedy after test-firing of its four main engines on a test stand in Mississippi later this year.

Vast lava tubes pock the surface of the moon and Mars, and could protect explorers from the elements. But first someone needs to explore them.
