Luxembourg (SPX) Feb 24, 2023
The Government of Luxembourg has announced that it will use SES's O3b mPOWER system as a crucial resilient satcom infrastructure for Luxembourg, its partners, and NATO in the areas of defense and security, disaster recovery, and more. The program, MEO Global Services (MGS), valued at 195 million euro over 10 years, will authorize the acquisition and operation of O3b mPOWER services, subject to a

Although the Pony Express lasted only a short time in the mid-1800s before being outperformed by the transcontinental telegraph, it inspired a concept for a string of small satellites to transport data from Mars to Earth and help alleviate the data logjam currently occurring in the Deep Space Network.

The Sun emitted a strong solar flare, peaking at 3:16 p.m. ET on Feb. 17, 2023. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.
NASA's Solar Dynamics Observatory captured this image of a solar flare—as seen in the bright flash in the upper left—on Feb. 17, 2023.
The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in teal.
Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.
This flare is classified as an X2.2 flare. X-class denotes the most intense flares, while the number provides more information about its strength.

Galactic Energy, a private space company in Beijing, plans to launch one of its own rockets from the sea in the coming summer, which, if it succeeds, will become the first sea-based launch by the country's private sector.

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.

After the drive, Curiosity's wheel scuffed the rippled sand feature right in front of us, which you can see in the image above. This scuff - nicknamed 'Taracua' - is the subject of both ChemCam and Mastcam observations looking at both the surface and interior of the feature.

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.
