NASA Crew-4 preps for launch but liftoff delayed as Ax-1 mission waits to leave ISS
Thursday, 21 April 2022 02:30
NASA's next crew of astronauts planned to launch no earlier than Saturday, but space agency officials are preparing to delay the flight because of weather problems preventing the return of Axiom Space's first mission crew from the International Space Station.
The Ax-1 crew originally planned for a 10-day mission, part of the first-ever private astronaut mission to the International Spac Mars rover searches for evidence of past life at ancient river delta

NASA's Perseverance rover, searching for evidence of past life on Mars, has completed a 31-Martian-day journey of roughly 3 miles after collecting eight rock-core samples from its first science campaign.
As of April 13, the rover was "at the doorstep of Jezero Crater's ancient Martian river delta" searching for signs of microscopic life, according to NASA.

The early universe may chirp about unknown physics. A University of Helsinki research team has demonstrated how an early universe phase transition will lead to gravitational wave signals potentially visible in the upcoming satellite missions. The research results were recently published in the prestigious journal Physical Review Letters.

Thursday, 21 April 2022 02:30
The X-59, NASA's quiet supersonic experimental aircraft, has arrived back at Lockheed Martin's Skunk Works facility in Palmdale, California, following several months of critical ground tests in Ft. Worth, Texas.
Ground tests on the X-59 were done to ensure the aircraft's ability to withstand the loads and stresses of supersonic flight - or flight at speeds faster than Mach 1. The vehicle's Chinese satellite obtains global gravity field data

China's Tianqin-1 satellite has acquired the global gravity field data during its in-orbit operation, according to Sun Yat-sen University in south China's Guangdong Province.
The satellite was launched in December 2019 to test the technologies of the space-based gravitational wave detection program "Tianqin." The program Tianqin, meaning "harp in the sky," was initiated by the university i California field campaign is helping scientists protect diverse ecosystems

Chinese scientists will soon have a new space-based tool to advance their research on the atmospheric environment and pollution.
After in-orbit tests, the Atmospheric Environmental Surveyor satellite will start its monitoring operations and send data to scientists, according to its designers at the Shanghai Academy of Spaceflight Technology.

A magnetosphere forms around any magnetized object, such as a planet, that is immersed within a stream of ionized gas, called plasma. Because Earth possesses an intrinsic magnetic field, the planet is surrounded by a large magnetosphere that extends out into space, blocks lethal cosmic rays and particles from the sun and stars, and allows life itself to exist.

The moon, where no satnav has gone before
Wednesday, 20 April 2022 19:36
The test version of a unique satellite navigation receiver has been delivered for integration testing on the Lunar Pathfinder spacecraft. The NaviMoon satnav receiver is designed to perform the farthest ever positioning fix from Earth, employing signals that will be millions of times fainter than those used by our smartphones or cars.
"This engineering model of our NaviMoon receiver is the very first piece of hardware to be produced in the context of ESA's moonlight initiative, to develop dedicated telecommunications and navigation services for the moon," explains Javier Ventura-Traveset, Head of ESA's Navigation Science Office and managing all ESA lunar navigation activities.
"It will be flown aboard the Lunar Pathfinder mission into orbit around the moon, from where it will perform the furthest satellite navigation positioning fix ever made, at more than 400 000 km away to an accuracy of less than 100 m. This represents an extraordinary engineering challenge, because at such a distance the faint Galileo and GPS signals it makes use of will be barely distinguishable from background noise.
