NASA's Perseverance rover has logged another extraterrestrial first on its latest mission to Mars: converting carbon dioxide from the Martian atmosphere into pure, breathable oxygen.

"This is a critical first step at converting carbon dioxide to oxygen on Mars," said Jim Reuter, associate administrator for NASA.

According to AFP, the technology demonstration took place on April 20, and NASA hopes future versions of the used experimental instrument could pave the way for future human Martian explorations.

Not only can the process produce oxygen for future astronauts to breathe, but it could make hauling vast amounts of oxygen over from Earth to use as rocket propellant for the return journey unnecessary. The instrument, dubbed MOXIE (short for Mars Oxygen In-Situ Resource Utilization Experiment), is a golden box the size of a car battery, and is located inside the front right side of the rover.

It uses electricity and chemistry to split carbon dioxide molecules, to produce oxygen and carbon monoxide. In its first run, MOXIE produced 5 grams of oxygen, equivalent to about 10 minutes of breathable oxygen for an astronaut carrying out normal activity.

MOXIE's engineers will now run more tests and try to step up its output. It is designed to be able to generate up to 10 grams of oxygen per hour. Designed at the Massachusetts Institute of Technology, MOXIE was built with heat-resistant materials and designed to tolerate the searing temperatures of 800 Celsius required for it to run. A thin gold coating ensures it doesn't radiate its heat and harm the rover.

MIT engineer Michael Hecht said a one-ton version of MOXIE (the currently used instrument weighs 17 kg) could produce the approximately 25 tons of oxygen needed for a rocket to blast off from Mars.

Producing oxygen from Mars' 96 percent carbon dioxide atmosphere might be a more feasible option than extracting ice from under its surface then electrolyzing it to make oxygen. Perseverance landed on the Red Planet on February 18 on a mission to search for signs for past life.

Japan's space agency aborted an engine test for the Epsilon S rocket on Tuesday following a fire at the test site, a failure that could push the rocket's debut launch beyond the March-end target and cause further delays in the national space program.
An explosion could be heard and a blaze could be seen shortly after the ground combustion test started at the Tanegashima Space Center in southwestern Japan, according to footage from public broadcaster NHK.
The Japan Aerospace Exploration Agency (JAXA) said the engine test encountered a "combustion abnormality" 49 seconds after the ignition. It said there was no indication of injury or damage to the outside facility, Reuters reported.
"JAXA will conduct a thorough investigation into the cause of the problem and consider countermeasures," Chief Cabinet Secretary Yoshimasa Hayashi said at a regular press briefing.
Hayashi, the top government spokesperson, said rocket development is "extremely important" to ensure the autonomy of Japan's space program.
JAXA partnered with the aerospace unit of heavy machinery maker IHI to develop Epsilon S, the next generation in the Epsilon solid-fuel small rocket series. Shares in IHI were down as much as 6% in Tokyo trade. An IHI Aerospace spokesperson said the company is investigating the cause.
Epsilon S's debut flight was slated by the end of the fiscal year through March 31 depending on the success of Tuesday's engine test.
The test was conducted after previous failures triggered months of investigation that have delayed space missions and satellite launch plans.
In July last year, an Epsilon S engine test failed due to thermal damage to its ignition systems. That followed a launch failure in 2022.
JAXA's larger flagship rocket H3, built by Mitsubishi Heavy Industries, failed at its first launch last year but has succeeded in three flights this year, launching Japanese satellites and winning orders including from French satellite operator Eutelsat.
The H3 and Epsilon S are central to JAXA's ambition to build cost-competitive rockets amid the rise of American commercial launch providers such as market leader SpaceX and small rocket maker Rocket Lab.
In the private sector, IHI-backed Space One is set to attempt the second launch of its Kairos small rocket on Dec. 14 after the first flight exploded in March. It aims to become the first Japanese business to put a satellite in orbit.
