Nasa mars rover extracts oxygen planet crack#

“The production of oxygen from the Martian atmosphere is a critical path item in Elon Musk’s efforts to build a city on Mars.” “The MOXIE technology is a huge step toward supporting large settlements of people on the Red Planet,” said Dale Skran, NSS Chief Operating Officer. “You need about 25 tons of oxygen for about seven tons of fuel, so the low-hanging fruit is the 25 tons of oxidizer.” This technology could make traveling to Mars much less expensive and more routine, and supply human settlements there with a ready supply of breathable oxygen.

The oxygen is an oxidizer, and much more of that is needed than rocket fuel when traveling to Mars and back. “A full-scale system would produce maybe 200 times what MOXIE produces and have it ready for astronauts to combine with a fuel, which they could bring from Earth,” said Mike Hecht, the Principal Investigator on MOXIE. That oxygen, in sufficient quantities, will ultimately be used not just to support human settlements on the Red Planet, but can also serve as rocket fuel for the return trip home.

MOXIE is in essence a reverse fuel cell, using a high-temperature heater to crack carbon dioxide in the Martian air to make breathable oxygen. “While this is just a small demonstrator unit, future plans call for NASA to send a vastly scaled-up version that will extract many tons of oxygen for use by future missions to, and settlers on, Mars.” “The success of MOXIE is an amazing accomplishment that has vast implications for supporting humans on Mars,” said Anita Gale, CEO of the National Space Society. The scientists detailed their findings online today (July 12) in the journal Nature.On Tuesday, an experimental unit on NASA’s Perseverance rover called MOXIE achieved a remarkable milestone on Mars, extracting oxygen from the Martian atmosphere. 'To confirm the presence of organics and their specific types, we would need the samples to be returned to Earth,' Sharma said. The scientists could not identify specific organic molecules. 'That opens the possibility of different formation, preservation or transportation mechanisms across the crater and, more broadly, the surface of Mars.' 'Seeing that the possible organic signals differ in terms of type, number of detections and distribution between the two units of the crater floor was surprising and exciting,' Sharma said. These organic compounds mostly appeared connected to minerals linked to water. These occurred in a variety of patterns in space within Máaz and Séítah, suggesting they might have originated from a number of different minerals and mechanisms of formation. The scientists discovered evidence of many different classes of organic molecules.

Sharma and her colleagues found signs of organic molecules in all 10 targets that Perseverance drilled into at Máaz and Séítah, covering a span of time from at least about 2.3 billion to 2.6 billion years ago. The fingerprint of wavelengths in the glow from a molecule can help identify it. When ultraviolet light from SHERLOC illuminates organic compounds, they can glow much like material beneath a blacklight.

The researchers focused on SHERLOC data from Máaz and Séítah, two rock formations on the Jezero Crater floor.

SHERLOC is the first tool on Mars capable of conducting fine-scale mapping and analysis of organic molecules. Specifically, the scientists examined data from the Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) instrument onboard Perseverance. The crater floor also possesses clays and other minerals that may preserve organic materials. In February 2021, the rover landed within Jezero Crater, the site of an ancient lake basin that prior work suggested displayed high potential for past habitability. In the new study, Sharma and her colleagues analyzed data from Perseverance. 'As planetary scientists and astrobiologists, we are very careful with laying out claims - claiming that life is the source of organics or possible biosignatures is a last-resort hypothesis, meaning we would need to rule out any non-biological source of origin,' Sharma said.
