Leonard David is an award-winning space journalist who has been reporting on space activities for more than 50 years. Currently writing as Space.com's Space Insider Columnist among his other projects, Leonard has authored numerous books on space exploration, Mars missions and more, with his latest being 'Moon Rush: The New Space Race' published in 2019 by National Geographic. He also wrote 'Mars: Our Future on the Red Planet' released in 2016 by National Geographic. Leonard has served as a correspondent for SpaceNews, Scientific American and Aerospace America for the AIAA. He was received many awards, including the first Ordway Award for Sustained Excellence in Spaceflight History in 2015 at the AAS Wernher von Braun Memorial Symposium.

The challenge all along, Hecht added, has been to define ways to operate on Mars more efficiently by cranking out a higher yield of oxygen.Hecht presented a review of MOXIE, detailing a Martian year of on-the-spot resource utilization on the Red Planet at the 23rd meeting of the Space Resources Roundtable, held June 6-9 at the Colorado School of Mines.
MOXIE weighs roughly 40 pounds and is designed to pull in Martian air using a pump before using an electrochemical process to separate one oxygen atom from each molecule of carbon dioxide. As a byproduct, carbon monoxide is produced, as is a black residue of solid carbon that can gum up the works inside the device, Hecht said. So voltage vigilance is required as MOXIE performs its high-temperature, oxygen-making work, he added.
Technicians in a clean room carefully lower the Mars Oxygen In-Situ Resource Utilization Experiment instrument into the belly of the Perseverance rover.in calendar year 2021, mostly to prove that the instrument can operate in the different conditions the planet experiences throughout the Martian year.
In 2022, MOXIE technologists focused more on pushing the unit's capabilities, as well as developing new operating modes. All in all, the earlier start-stop set of 14 runs added up to 1,000 minutes of operating time."It's been an exciting ride," Hecht told the Colorado School of Mines audience. But MOXIE is a technology demonstration, and like many other demonstrators, its long-term life is tied to funding. Research money for MOXIE is set to end at year's end, Hecht said, with the MIT lab that carries out the work on the lookout for new collaborations.

Extending Earth's Internet to Mars With Orbital Data ServersMore spacecraft is due to fly to Mars and will send their data home. Human explorers will want to access research documents and communicate the findings to Earth. This will require extending Earth's internet to Mars. A new study suggests that Mars will eventually require its constellation of satellites, provide local computing at Mars, and supply as much information as possible locally.
