Gaze up at the Moon on any night and you will see a barren world displaying all manner of shades of grey. Aside from the obvious craters and lunar maria, the surface of the Moon is covered in the fine, dusty lunar regolith. The Apollo astronauts in the 60’s and 70’s learned that it was electromagnetically charged and was very abrasive posing a problem for mechanical equipment. Now a new payload on the Commercial Lunar Payload Services initiative will explore the regolith even further

Saturn’s rings are among the most glorious, stunning, and well-studied features in the Solar System. However, their age has been difficult to ascertain. Did they form billions of years ago when the planet and the Solar System were young? Or did they form in the last few hundred millions of years?The latest new research shows that the iconic rings are, in fact, very old.We first became aware of Saturn’s opulent rings hundreds of years ago. Galileo was the first to see them, though he

Exploring asteroids and other small bodies throughout the solar system has gotten increasingly popular, as their small gravity wells make them ideal candidates for resource extraction, enabling the expansion of life into the solar system. However, the technical challenges facing a mission to explore one are fraught – since they’re so small and variable, understanding how to land on one is even more so. A team from the University of Trieste in Italy has proposed a mission idea that co

Nieuwjaar in de ruimte: hoe vieren astronauten op het ISS de jaarwisseling?

30-12-2024 13:02 via scientias.nl

Wanneer wij straks op aarde het nieuwe jaar inluiden, maken we een feestje van middernacht. Maar hoe werkt dat eigenlijk als je in een ruimtestation zweeft dat elke 90 minuten rond de aarde cirkelt? Het Internationale Ruimtestation (ISS) vliegt met een snelheid van ongeveer 28.000 kilometer per uur rond de aarde. Bij deze duizelingwekkende snelheid […]

Ingenuity became the first aircraft to fly on another world in the first half of 2021. It explored the Martian terrain from above proving that powered air flight was a very efficient way to move around alien worlds. Now NASA have released a computer rendering of their next design, the Mars Chopper! Ingenuity was a small helicopter, or rather more a drone, that was carried to Mars on board the Perseverance rover mission in 2020. It was designed as a technology demonstration to prove that pow
