NASA's next Mars rover attached to rocket before July 30 launch

NASA engineers have attached its Mars rover to the top of the rocket that will send it toward the Red Planet as the US space agency now targets July 30 for its launch.

Encased in the nose cone that will protect it during launch, the “Perseverance” rover and the rest of the Mars 2020 spacecraft — the aeroshell, cruise stage, and descent stage — were affixed to a United Launch Alliance Atlas V booster on July 7, NASA said.

With the mating of spacecraft and booster complete, the final testing of the two — separately and as one unit — will be underway, NASA said.

The targeted launch date of the mission has been pushed back three times so far – first to July 20, then to July 22 and now to July 30.

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 August 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.

No matter what day Perseverance lifts off during its July 30 to August 15 launch period, it will land in Mars’ Jezero Crater on February 18, 2021, NASA said. IANS
