Two astronauts concluded a spacewalk Friday outside the International Space Station and installed a second of six new solar arrays that will boost the orbiting laboratory's electrical power supply. Shane Kimbrough and Thomas Pesquet exited the space station about 8 a.m. EDT. They successfully mounted and rolled out a 60-foot-long solar array, known as iROSA or International Space Statio

An asteroid strike on Earth could be prevented by new technology launching into space this year, involving a Queen's University Belfast scientist. Professor Alan Fitzsimmons from the Astrophysics Research Centre at Queen's is playing a role in two space missions that will measure how hard it is to deflect an asteroid. He will be telling people about it in an online public talk on World Ast

Ever wondered how Mars rovers take a selfie? Color video from NASA's Perseverance shows how the rover captured the historic April 6, 2021, image of itself beside the Ingenuity Mars Helicopter. As a bonus, the rover's entry, descent, and landing microphone captured the sound of the arm's motors whirring during the process. Selfies allow engineers to check wear and tear on the rover. But the

A giant comet from the outskirts of our Solar System has been discovered in 6 years of data from the Dark Energy Survey. Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times. It has an extremely elongated orbit, journeying inward from the distant Oort Cloud over millions of years. It i

Using data originally gathered for spacecraft ‘housekeeping’ aboard ESA’s Rosetta and Mars Express missions, scientists have revealed how intense bursts of high-energy radiation, known as cosmic rays, behave at Mars and throughout the inner Solar System.
