Abu Dhabi’s $1 Billion Bet Sends Mistral AI Models Into Orbit on 50-Satellite Fleet
Abu Dhabi-based Marlan Space and Loft Orbital have announced a $1 billion consortium to expand the Altair satellite constellation from 10 to 50 AI-powered satellites. The project, unveiled at the Inte
No sample deliberately collected on Mars has ever been examined in a laboratory on Earth, because bringing one home requires launching a sealed container from the Martian surface, autonomously rendezvousing with another spacecraft in orbit, and carrying it across interplanetary space; China plans to accomplish all three with Tianwen-3 and return at least 500 grams of Martian material around 2031.
China’s Tianwen-3 mission is planned to become the first mission to deliberately collect Mars samples and return them to Earth. A 2025 *Nature Astronomy* perspective led by chief scientist Hou Zengqia
A NASA Photo Processing Technique to Study Mars Has Discovered Ancient Art on Earth

Scientists who read 16 years of radio tracking from three Mars orbiters say the mantle beneath the planet’s southern highlands runs 200 to 400 degrees Celsius hotter, averaged over the whole depth of the mantle, than the mantle beneath the northern plains, an inference drawn from the way Mars flexes under the Sun across each Martian year
Researchers have used tidal tomography to probe the interiors of Earth, the Moon, and now Mars by measuring how a body deforms under tidal forces. In Mars’s case, Alexander Berne and colleagues analyz

Evolution - NASA Science
NASA’s overview of galaxy evolution explains that galaxies have been studied in great detail through deep-space observations such as the Hubble Ultra Deep Field, which revealed about 10,000 galaxies a
It's tempting to assume faster engines make faster spacecraft, but Parker Solar Probe's record 430,000 miles per hour came mostly from gravity: seven Venus flybys spent nearly seven years bending its orbit closer to the Sun, until the Sun's own pull accelerated it faster than any human-made object in history.
Parker Solar Probe’s record speed of about 430,000 miles per hour was achieved not mainly through engine power, but through gravity and careful orbital design. Launched in August 2018 aboard a Delta I
We think of astronauts as floating in zero gravity, but the International Space Station is still deep inside Earth’s pull, where gravity is nearly 90% as strong as it is on the ground. What looks like weightlessness is really the station and its crew falling around the planet at about 28,000 kilometres per hour.
Astronauts on the International Space Station (ISS) are not experiencing “zero gravity” in the literal sense. The station orbits about 400 kilometers above Earth, where gravity is still about 90% as s

When a human and a dog gaze into each other's eyes, both of them release oxytocin — the same hormone released between a human mother and her infant during nursing — and Japanese researchers reported in 2015 that this cross-species chemical feedback loop appears to be unique to dogs and their humans and does not occur in wolves
A 2015 study by Japanese researchers found that when humans and dogs make mutual eye contact, both species release oxytocin, a hormone strongly linked to social bonding. This “positive feedback loop”
