Pasadena, CA – NASA’s Apollo 11 command module Columbia splashed down in the Pacific Ocean, fulfilling President John F. Kennedy’s goal to land a man on the Moon and return him safely to Earth on July 24th, 1969.
Among the mission’s many firsts was the acquisition and return of the first samples from another celestial body. Findings based on the 47 pounds (21.5 kilograms) of lunar rock and soil rewrote the textbooks on both the Moon and solar system, and the samples are still being studied today by researchers using new and more sensitive instruments.
With its launch window opening on July 17th, 2020 – less than a year from today, NASA’s Mars 2020 rover will mark another first: The rover will not only seek signs of ancient habitable conditions and past microbial life but will collect rock and soil samples, storing them on the planet’s surface for a future mission to retrieve.
“Apollo 11 demonstrated the immense value of returning samples from other worlds for analysis here on Earth,” said Thomas Zurbuchen,NASA’s associate administrator for the Science Mission Directorate.
“Today, we are standing on the shoulders of Apollo, preparing for the launch of the initial step in humanity’s first round trip and sample return from another planet – Mars,” Zurbuchen stated.
The 2020 rover will land at Jezero Crater on February 18th, 2021, equipped with a system to cache science samples in tubes that will be delivered to a safe drop-off site.Two subsequent missions, currently in the concept stage, would be needed to bring the Mars 2020 samples home.
One mission would land a rocket (the Mars Ascent Vehicle) and a spacecraft carrying a rover about the size of NASA’s Opportunity Mars rover at Jezero Crater. The rover would gather the cached samples and carry them back to the ascent vehicle, which would then launch the samples into Mars orbit. The other mission (which would already be in orbit around Mars when the ascent vehicle launches) would rendezvous with and capture the orbiting samples, before returning them to Earth.
“NASA and the European Space Agency are solidifying these exciting mission concepts to retrieve the samples,” said Zurbuchen. “Just as the first samples returned to Earth from the Moon’s Sea of Tranquility made history, the first samples returned to Earth from another planet will make history and amaze us all over again. And those samples will come from Mars’ Jezero Crater.”
While the significance of being part of the first step in a sample return mission from another planet is not lost on anyone involved with Mars 2020, it has a special significance to John McNamee, Mars 2020 project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California.
JPL is building and will manage operations of the Mars 2020 rover for the NASA Science Mission Directorate at the agency’s headquarters in Washington. NASA will use Mars 2020 and other missions, including to the Moon, to prepare for human exploration of the Red Planet. The agency plans to establish a sustained human presence on and around the Moon through NASA’s Artemis lunar exploration plans.
