Antarctica is a tough place to work, for obvious reasons- it's bitterly cold, remote, and wild. However, it's one of the best places in the world to hunt for meteorites. That's partly because Antarctica is a desert, and its dry climate limits the degree of weathering the meteorites experience.

Chinese rocket researchers are now definite on the overall structural design for the nation's super-heavy carrier rocket, known as the Long March 9, a project insider said on Wednesday.
Gu Mingkun, a senior rocket designer at the China Academy of Launch Vehicle Technology, the country's leading rocket maker, said at a news conference that the baseline model of the Long March 9 will be a la What is the Chemistry and Mineralogy Instrument?

Minerals are like a time capsule; they provide a record of what the environment was like at the time they formed. Different minerals are linked to different kinds of environments. The temperature, pressure, and chemical ingredients that were present - including water - determine what minerals form and how they are altered.
For example, gypsum is a mineral that contains calcium, sulfur, and Light-based tech could inspire Moon navigation and next-gen farming

Super-thin chips made from lithium niobate are set to overtake silicon chips in light-based technologies, according to world-leading scientists in the field, with potential applications ranging from remote ripening-fruit detection on Earth to navigation on the Moon.
They say the artificial crystal offers the platform of choice for these technologies due to its superior performance and rece How was the solar system formed? The Ryugu asteroid is helping us learn

Mineral samples collected from the Ryugu asteroid by the Japan's Hayabusa2 spacecraft are helping UCLA space scientists and colleagues better understand the chemical composition of our solar system as it existed in its infancy, more than 4.5 billion years ago.

All kinds of exoplanets orbit very close to their star. Some look like the Earth, others like Jupiter. Very few, however, are similar to Neptune. Why this anomaly in the distribution of exoplanets?

Astronomers have released a gargantuan survey of the galactic plane of the Milky Way. The new dataset contains a staggering 3.32 billion celestial objects - arguably the largest such catalog so far. The data for this unprecedented survey were taken with the Dark Energy Camera, built by the US Department of Energy, at the NSF's Cerro Tololo Inter-American Observatory in Chile, a Program of NOIRLa Guerrilla RF announces entry into the satellite communications industry

It was a historic journey. As part of NASA's Artemis I mission, the Orion spacecraft, powered and supplied by the European Service Module (ESM), flew to the Moon and back for the first time. On board were the two female astronaut phantoms, Helga and Zohar - part of the first experiment conducted in space to measure the radiation exposure to which the female body is exposed during such a flight.

After 30 years in orbit, mission operations for the joint NASA-JAXA Geotail spacecraft have ended, after the failure of the spacecraft's remaining data recorder.
Since its launch on July 24, 1992, Geotail orbited Earth, gathering an immense dataset on the structure and dynamics of the magnetosphere, Earth's protective magnetic bubble. Geotail was originally slated for a four-year run, but ABL Space Systems blames RS1 launch failure on loss of power

NASA's Geotail mission operations come to an end after 30 years

After 30 years in orbit, mission operations for the joint NASA-JAXA Geotail spacecraft have ended, after the failure of the spacecraft's remaining data recorder.
After its launch on July 24, 1992, Geotail orbited Earth, gathering an immense dataset on the structure and dynamics of the magnetosphere, Earth's protective magnetic bubble. Geotail was originally slated for a four-year run, but the mission was extended several times due to its high-quality data return, which contributed to over a thousand scientific publications.
While one of Geotail's two data recorders failed in 2012, the second continued to work until experiencing an anomaly on June 28, 2022. After attempts to remotely repair the recorder failed, the mission operations were ended on November 28, 2022.
"Geotail has been a very productive satellite, and it was the first joint NASA-JAXA mission," said Don Fairfield, emeritus space scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and NASA's first project scientist for Geotail until his retirement in 2008.
