After a breakdown: NASA’s Capstone satellite swung into a special lunar orbit

Capstone is now orbiting the Moon in the same orbit as the proposed Gateway space station. This was preceded by a flight full of breakdowns. Artist's impression of Capstone on the moon (Image: Illustration by NASA/Daniel Rutter) NASA's Capstone probe has reached the moon after a mishap-filled flight. The probe entered a near-perpendicular halo orbit (NRHO) on Sunday, … Continue reading After a breakdown: NASA’s Capstone satellite swung into a special lunar orbit

X-37B: US spaceplane returned after 908 days in space

The experimental US space glider X-37B has now completed six missions, one longer than the others. Several records were set at the last one. The space glider after landing  (Image: Boeing/US Space Force) The US Space Agency's experimental unmanned reusable X-37B spacecraft has landed again, setting a new record with a mission duration of 908 days … Continue reading X-37B: US spaceplane returned after 908 days in space

NASA must quickly launch the Artemis I rocket before its boosters expire

A countdown ticks for some components of the Artemis I rocket, still on the ground. The Space Launch System boosters will expire in December 2022, if the mission has still not gone to the Moon. The first mission of the ambitious Artemis program is still grounded. The Space Launch System (SLS) rocket was supposed to fly to the Moon in the summer of … Continue reading NASA must quickly launch the Artemis I rocket before its boosters expire

NASA was able to observe the basement of Mars thanks to a meteorite

NASA has just made a great discovery on Mars. A crater 150 meters in diameter was created by a meteorite in 2021. NASA generally makes relatively few announcements to the press. When she calls journalists around the world, it's usually not for nothing. So when yesterday afternoon the American space agency confirmed the holding of a press conference, … Continue reading NASA was able to observe the basement of Mars thanks to a meteorite

Mysterious radiation bursts about every 1000 years: Danger for modern technology

Erratic but repeated, the Earth has been hit by mysterious bursts of radiation. The cause is unclear, but a recurrence would be devastating. Roughly once every thousand years, mysterious and potentially devastating astrophysical events have left their mark on tree rings across the globe. That's what Australian researchers have determined, who now warn that the probability of … Continue reading Mysterious radiation bursts about every 1000 years: Danger for modern technology

Fermi Paradox: Sun may be too short-lived for extraterrestrial colonization

For decades people have been puzzling over why the Milky Way is apparently not populated. But maybe it is, and sun-like stars have been left out. (Image: ESO/S. Guisard ( www.eso.org/~sguisard )) It is possible that the Milky Way has long been settled by one or more extraterrestrial civilizations and the solar system has been bypassed because the … Continue reading Fermi Paradox: Sun may be too short-lived for extraterrestrial colonization

On Mars, InSight is at the mercy of a storm the size of a continent

An imposing Martian storm could pose a danger to the InSight mission. NASA monitors the evolution of the situation, from the sky of Mars. A continent-sized dust storm is swirling around Mars. NASA is closely monitoring the situation, because, 3,500 km away, is one of its robots sent to the red planet. This is InSight, whose mission should come to an end … Continue reading On Mars, InSight is at the mercy of a storm the size of a continent

How AIs predict wars

Although the outbreak of war is usually viewed as an irrational act of violence, the risk of war can be calculated. (Image:  Danielle Tunstall, public domain (Creative Commons CC0) The outbreak of wars, riots, strikes, and unrest can actually be predicted - with sober scientific methods, political and social theories, but also data analysis and artificial intelligence. In … Continue reading How AIs predict wars

NASA probe Dart creates an impact on asteroids – now it’s time to wait

NASA celebrates a collision with the small moon of a small asteroid. It should be a big step on the way to better protection of planet earth. The asteroid moon Dimorphos seconds before impact (Image: Screenshot NASA TV (public domain)) NASA's Dart crashed into the asteroid moon Dimorphos as planned. The team of scientists celebrates this success. Even choosing … Continue reading NASA probe Dart creates an impact on asteroids – now it’s time to wait

More time for decarbonization: 125 aircraft could cool polar regions

With comparatively limited geoengineering, the polar regions could be cooled and climate change slowed down, say US researchers. 125 military tanker aircraft are to be used (Image: US Air Force) A Yale University researcher suggests reflecting the sun off the Earth's poles off microscopic particles and slowing global warming. This is reported by Sky News from Great … Continue reading More time for decarbonization: 125 aircraft could cool polar regions
