Voyager 1’s flight data system collects information from the spacecraft’s science instruments and bundles it with engineering data that reflects its current health status. But since November, Voyager 1’s flight data system had been stuck in a loop. By investigating the readout, the team determined the cause of the issue: 3% of the flight data system’s memory is corrupted. Members of the Voyager flight team celebrate after receiving the first coherent data from Voyager 1 in five months at NASA's Jet Propulsion Laboratory on April 20. And younger engineers are coming onto the Voyager team and contributing their knowledge to keep the mission going.”

☆ NASA mission achieves most distant demo of laser communications across space
▼ + stars: | 2023-11-24 | by ( Ashley Strickland | ) edition.cnn.com time to read: +7 min

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.

NASA's Jet Propulsion Laboratory reconnected with the Voyager 2 space probe after losing it. The agency's Jet Propulsion Laboratory sent an interstellar "shout" more than 12.3 billion miles which got the probe's attention after an error by NASA officials rendered the probe temporarily unreachable. According to the agency, it took the signal 18.5 hours for commands to reach Voyager 2 through the vastness of space. The operation only had a small chance of success, a spokeswoman for the Jet Propulsion Laboratory told The Times. "After two weeks of not hearing anything, we're back to getting unique data from the interstellar medium," said Linda Spilker, a planetary scientist at the Jet Propulsion Laboratory and the lead mission scientist for Voyager 2.

It was one of a twin set of spacecraft designed to take images of Mars, and the first one failed. Dan Goods/NASA/JPL-CaltechThe transmission was incredibly slow by today’s standards, given that the Perseverance rover regularly sends back batches of high-resolution images from Mars. Together, they revealed craters on the Martian surface and clouds floating above in the atmosphere, both of which surprised scientists. The highest-resolution Mariner 4 image (right) revealed the cratered Martian surface from 7,830 miles (12,601 kilometers) above. JPL/NASAThe snapshots showed less than 1% of the Martian surface, missing the more diverse features on the planet’s surface that later missions such as Viking 1 would capture.

The latest evidence comes from an instrument called SHERLOC mounted on the six-wheeled rover's robotic arm that enables a detailed mapping and analysis of organic molecules. They obtained evidence indicating the presence of organic molecules in multiple rock samples, including some collected for potential return to Earth for future analysis. Signs of organic molecules were first detected on Mars in 2015 by a different rover called Curiosity, followed by more evidence in subsequent years. With Perseverance now detecting possible signatures of organic molecules, the evidence is accumulating that organic molecules may be relatively common on Mars, though at low levels. "There are both biotic and abiotic mechanisms that can form organic molecules.

The discovery was based on data collected by NASA's Cassini spacecraft, the first to orbit Saturn, during its 13-year landmark exploration of the gaseous giant planet, its rings and its moons from 2004 to 2017. The same team previously confirmed that Enceladus' ice grains contain a rich assortment of minerals and complex organic compounds, including the ingredients for amino acids, associated with life as scientists know it. Another is Jupiter's larger moon Europa, which also is believed to harbor a global ocean of liquid water beneath its icy surface. "This key ingredient could be abundant enough to potentially support life in Enceladus' ocean," said co-investigator Christopher Glein, a planetary scientist at Southwest Research Institute in San Antonio, Texas. "Whether life could have originated in Enceladus' ocean remains an open question," Glein said.
