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.
“We have four objectives,” Ken Williford, Deputy Project Scientist for NASA’s Mars 2020 mission, told Astronomy earlier this year. “The first three are really our core science objectives. And the fourth is … preparing for human exploration.”
Perseverance’s science objects are: seeking out sites that were potentially habitable in the past, looking for signs of ancient microbes within rocks known to preserve life, and collecting and storing promising rock samples for a future return mission.
