NASA teams set for second Artemis II wet dress rehearsal
NASA is preparing for the second wet dress rehearsal of the Space Launch System rocket and Orion spacecraft ahead of the Artemis II test flight, targeting Thursday, Feb. 19, as the day to load propellants into the vehicle at Kennedy Space Center in Florida.
Teams spent the weekend replacing a filter in ground support equipment that was suspected of restricting liquid hydrogen flow during a Hypersonica completes milestone hypersonic missile flight test in Norway
Hypersonica has completed its first hypersonic test flight at Andoya Space in Norway, marking what the company describes as a major step toward a European sovereign hypersonic strike capability by 2029.
The Anglo-German defense and aerospace company reported that its missile prototype accelerated to speeds above Mach 6 and flew more than 300 kilometers during the mission. All systems perfo Study revisits chances of detecting alien technosignatures
For more than sixty years, astronomers have searched the sky for signs of advanced extraterrestrial technology, scanning the Milky Way for artificial radio transmissions, optical flashes and excess infrared heat.
Despite these efforts, no technosignature has been confirmed so far, a silence often attributed to the fact that only a tiny fraction of the cosmic search space has been explored. New 'Mars GPS' lets Perseverance pinpoint its location within 25 centimeters

Hubble, Euclid & Subaru uncover dark galaxy
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.
Revealed: 10 new insights in climate science
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.
