Euclid spacecraft prepares to probe universe's dark mysteries

For now, Europe's Euclid spacecraft sits quietly in a sterilized room in the south of France, its golden trim gleaming under the fluorescent light.
But in a few months the space telescope will blast off on history's first mission to search for two of the universe's greatest mysteries: dark matter and dark energy.
Though together they make up 95 percent of the universe, almost nothing is known about either—a glaring hole in scientific understanding that Euclid project manager Giuseppe Racca dubbed a "cosmic embarrassment".
Aiming to shed light on these dark secrets, the European Space Agency's mission will chart a 3D map of the universe encompassing two billion galaxies across more than a third of the sky.

MAVEN status update
Friday, 24 February 2023 16:57 Write a comment
NASA's MAVEN spacecraft entered safe mode on Feb. 16 after encountering an issue with its Inertial Measurement Unit (IMU), which measures the spacecraft rate of rotation for use in determining its pointing. The IMU had been powered up in preparation for a minor maneuver targeted to reduce eclipse durations in 2027.
On Feb.17, MAVEN exited safe mode and is currently operating in all stellar mode, a mode that does not rely on IMU measurements such that the IMU can be powered off to conserve its lifetime. The maneuver will be waived as the team evaluates the path forward. Relay activities and nominal science operations are scheduled to resume on Feb. 23.
MAVEN launched in November 2013 and entered Mars' orbit in September 2014. The mission's goal is to explore the planet's upper atmosphere, ionosphere, and interactions with the Sun and solar wind to explore the loss of the Martian atmosphere to space. Understanding atmospheric loss gives scientists insight into the history of Mars' atmosphere and climate, liquid water, and planetary habitability.

Russia launched an unmanned Soyuz spacecraft to the International Space Station on Thursday to replace one that leaked coolant after it was struck by a meteoroid last year, stranding two cosmonauts and a NASA astronaut in space.
The Soyuz MS-23 spacecraft was launched with 948 pounds of supplies for the astronauts from the Baikonur Cosmodrome in Kazakhstan at 7:24 p.m. EST, which was br SuperCam's AI capabilities enhanced with AEGIS upgrade

As Perseverance celebrates its second anniversary on Mars, our team is reflecting on the rover's remarkable journey so far. In the past two years, Perseverance has collected 18 Martian samples, traversed over 9 miles, transmitted over 200,000 images to Earth, supported the Ingenuity helicopter with its 42 flights, and much more.

Galactic Energy, a private space company based in Beijing, plans to make its first sea-based launch this summer, which could be the first by a private Chinese firm if successful. According to Xia Dongkun, a vice-president at Galactic Energy, the company has scheduled the launch of one of its Ceres 1 rockets in the Yellow Sea Ryugu Asteroid sample reveals organic-rich composition, first analysis shows

Asteroid Ryugu has a rich complement of organic molecules, according to a NASA and international team's initial analysis of a sample from the asteroid's surface delivered to Earth by Japan's Hayabusa2 spacecraft. The discovery adds support to the idea that organic material from space contributed to the inventory of chemical components necessary for life.

Earth and Venus are rocky planets of about the same size and rock chemistry, so they should be losing their internal heat to space at about the same rate. How Earth loses its heat is well known, but Venus' heat flow mechanism has been a mystery. A study that uses three-decade-old data from NASA's Magellan mission has taken a new look at how Venus cools and found that thin regions of the planet's Colossal sky map shows over one billion glowing galaxies
