After years of anticipation, NASA hopes to launch its latest robotic explorer, Perseverance, to Mars on Thursday, July 30, at 7:50 A.M. EDT. Set to depart Earth atop an Atlas V-541 rocket from historic Launch Complex 41 at Cape Canaveral Air Force Station in Florida, the ambitious rover is the latest in a long lineage of rolling robotic explorers that NASA has sent to the Red Planet.
If Mars 2020 is not able to blast off during its two-hour launch window tomorrow morning — due to hazardous weather or unforeseen technical issues — the space agency will have just two more weeks to get it done. That’s because after August 15, Mars and Earth will no longer be aligned in a way that allows for quick interplanetary travel, meaning NASA would have to store the rover for two years until the next favorable alignment.
However, if Perseverance does launch between July 30 and August 15, it’s expected to land in Mars' Jezero Crater on February 18, 2021. And once it touches down within the ancient martian lake and river delta, it will set to work on its main goals.
