Roscosmos appears to be having some issues with a spacecraft again. In December, the Soyuz MS-22 spacecraft that delivered three crewmembers of Expedition 68 to the International Space Station (ISS) reported a leak in its coolant loop. On February 11th, engineers at the Russian Mission Control Center outside Moscow recorded a depressurization in Progress 82, an uncrewed cargo craft docked with the Poisk laboratory module. The cause of these leaks remains unknown, but Roscosmos engineers (with support from their NASA counterparts) will continue investigating.

Oftentimes in astronomy, it takes a village of telescopes and people to make an amazing find. In the case of the quasar NRAO 530, it took a planet full of radio dishes ganged together to peer into its heart. Then, it took a major collaboration of scientists to figure out what the instruments were telling them.

Exploring Mars is hazardous work. Robotic missions that are sent there have to contend with extreme temperatures, dust storms, intermittent sunlight, and rough terrain. In recent years, two robotic missions were lost due to dust alone, and all that roving around has done a number on the Curiosity rover’s treads. It’s understandable why mission teams are pleasantly surprised when their missions make it through a rough patch. This was the case with the Ingenuity team when they discovered that the rotorcraft, which has been exploring Mars alongside Perseverance, survived the night and is back in working order.

Astronomers have discovered a galaxy with very little or no stellar mass. Galaxies like these are called ‘dark galaxies.’ It contains clouds of gas but very few stars, possibly none. This is the only isolated dark dwarf galaxy in the local universe.

NASA’s Perseverance Rover has reached another milestone. It’s finished caching its samples for a potential return to Earth. The sample depot is located in Mars’ Jezero Crater, where Perseverance is busy searching for signs of ancient life.

In a recent study published in Nature Astronomy, an international team of researchers led by NASA and The George Washington University examined data from an October 2020 detection of what’s known as a “large spin-down glitch event”, also known as an “anti-glitch”, from a type of neutron star known as a magnetar called SGR 1935+2154 and located approximately 30,000 light-years from Earth, with SGR standing for soft gamma repeaters. Such events occur when the magnetar experiences a sudden decrease in its rotation rate, which in this case was followed by three types of radio bursts known as extragalactic fast radio bursts (FRBs) and then pulsed radio emissions for one month straight after the initial rotation rate decrease.
