The European Space Agency (ESA) is preparing for the inaugural launch of the Celeste LEO-PNT in-orbit demonstration mission with the first two satellites scheduled to lift off no earlier than 24 March, aboard Rocket Lab’s Electron rocket from the company’s Māhia Launch Complex in New Zealand.

The Defense Innovation Unit plans to select companies to field and operate spacecraft before transferring them to government control within three years

Employing NASA/ESA Hubble Space Telescope in combination with ESA Euclid and ground-based NAOJ Subaru Telescope, astronomers identified a galaxy that appears to be almost entirely dominated by dark matter with only a smattering of stars. The galaxy, known as Candidate Dark Galaxy-2 (CDG-2), appears to contain just four globular star clusters (compared to the Milky Way’s 150-plus), and dimly shines with the light of only about 1 million Suns.

Each year, the world’s leading climate scientists evaluate the most critical evidence on how our planet is changing. Their assessments draw heavily on data from Earth-observing satellites – and the latest report delivers a stark warning: the planet’s energy balance is drifting further out of alignment, ocean warming is now accelerating, and the land’s capacity to absorb carbon is declining, along with other troubling trends.

Satellite imagery-to-report timelines would be reduced from hours to minutes
