NASA’s 2020 Mars Rover Scheme
As per NASA’s official statement, the Mars 2020 rover is based on its predecessor ‘Curiosity‘ which was launched in 2011. The car-sized rover is about 10 feet long, 9 feet wide, and 7 feet tall while weighing 1,050 kgs. The mission is expected to last for about 687 Earth days, equivalent to one Mars year. The rover is expected to land on February 18, 2021, at Jezero Crater, Mars. The official launch window ranges from July 17 to August 5, 2020, from the Cape Canaveral Air Force Station, Florida.
SpaceX’s Mars Game Plan
Elon Musk’s brainchild had stated its aspiration to send its first cargo mission to Mars in 2022. SpaceX’s first mission aircraft ‘Starship‘ is targetted at confirming resources, identifying hazards and placing initial power, mining & life support infrastructure. Its next mission will carry both cargo and crew and is scheduled for 2024. This second mission is aimed at building a propellant depot for future crew flights. Musk hopes to evolve this foundation of the first Mars Base into a self-sustaining civilization.
Clash of NASA-Musk
In a short series of back and forth tweets, Musk had reportedly blamed NASA’s bureaucracy for not yet returning astronauts to the moon. He talked about the progress of mankind from the train to the rocket, expressing his disappointment at not being able to return to the moon after its first flight 50 years ago. This feud comes amidst the US Congress proposing a new space bill. This promises to make NASA push back its moon landing mission to 2028 instead of 2024, and shift back it’s focus to the Mars one.
