CNN —An innovative experiment flying aboard NASA’s Psyche mission just hit its first major milestone by successfully carrying out the most distant demonstration of laser communications. The tech demo was designed to be the US space agency’s most distant experiment of high-bandwidth laser communications, testing the sending and receiving of data to and from Earth using an invisible near-infrared laser. NASA/JPL-CaltechIt’s not the first time laser communications have been tested in space. The first test of two-way laser communication occurred in December 2021 when NASA’s Laser Communications Relay Demonstration launched and went into orbit about 22,000 miles (35,406 kilometers) from Earth. And the Artemis II spacecraft will use laser communications to return high-definition video of a crewed journey around the moon.

☆ Earth received a message sent from a deep space laser — it took just 50 seconds to travel 10 million miles

The technological feat, using NASA's Psyche probe, broke new ground for deep space communications. AdvertisementNASA has achieved a world-first after sending a laser-beamed message to Earth from nearly 10 million miles away within 50 seconds. While the space agency has long been able to communicate with spacecraft using radio waves, it had never before been able to send information using lasers from that far into space. The feat, achieved using NASA's Deep Space Optical Communications (DSOC) experiment on board the Psyche spacecraft, could someday allow humans to stream video calls on Mars. The spacecraft then beamed back information using its laser.

☆ A device on NASA's Perseverance rover generated enough oxygen on Mars for a small dog to breathe for 10 hours. Astronauts could be next.

A device on NASA's Perseverance Rover converted Mars' thin air into oxygen. That's where the microwave-sized device called the Mars Oxygen In Situ Resource Utilization Experiment, aka MOXIE, comes in. AdvertisementAdvertisementMOXIE hitched a ride to Mars on NASA's Perseverance Rover in 2021 and has been hard at work ever since. A photo of NASA's Perseverance rover just feet above the Martian surface — part of a video several cameras recorded of the landing on February 18, 2021. Technicians at NASA's Jet Propulsion Laboratory lower the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) instrument into the belly of the Perseverance rover.

☆ Perseverance rover experiment creates oxygen on Mars for the final time

The microwave-size device called MOXIE, or Mars Oxygen In-Situ Resource Utilization Experiment, is on the Perseverance rover. The experiment kicked off more than two years ago, a few months after the rover landed on Mars. The instrument works by converting some of Mars’ plentiful carbon dioxide into oxygen. MOXIE works by dividing up carbon dioxide molecules, which include one carbon atom and two oxygen atoms. Lessons learned from the small MOXIE experiment can now be used to create a full-scale system that includes an oxygen generator that can also liquefy and store the oxygen.

☆ NASA's inflatable heat shield could land humans on Mars

The inflatable aeroshell looked to be in great condition after recovery, proving it can survive the rigors of atmospheric entry. The result: “a pretty resounding yes,” said Trudy Kortes, director of technology demonstrations at NASA’s Space Technology Mission Directorate. The mission aims to test the inflatable heat shield technology that could also land larger robotic missions on Venus or Saturn’s moon Titan or return hefty payloads to Earth. But an inflatable aeroshell could circumnavigate that dependency — and open up sending heavier missions to different planets. A double rainbow appeared across the sky over the LOFTID heat shield as it was transferred at port in Hawaii.

Atmosfera de pe Marte are 96% dioxid de carbon și doar 0,13% oxigen, față de Pământ, care are 21% oxigen. Oxigenul este, de asemenea, o parte integrantă a chimiei care propulsează o rachetă. Moxie este capabil să “dezbrace” atomii de oxigen din moleculele de dioxid de carbon, care sunt alcătuite dintr-un atom de carbon și doi atomi de oxigen. Mini-elicopterul a făcut istorie prin efectuarea primului zbor motorizat și controlat de un avion pe altă planetă. Deși nu pare impresionant, pentru a doua sa ieșire, elicopterul s-a ridicat la cinci metri deasupra solului, s-a deplasat lateral cu doi metri, s-a rotit, a făcut câteva fotografii și apoi a revenit la locul de decolare, pentru a ateriza și a se întoarce la roverul Perseverance.
