Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, has announced that hundreds of its radiation-hardened (rad-hard) integrated circuits (ICs), including over 50 different part numbers, are onboard the Artemis 1 launch that blasted off on November 16. Intersil-brand rad-hard ICs are part of the battery management systems, RS-25 engine control

Micrometeoroid strikes are an unavoidable aspect of operating any spacecraft. NASA's James Webb Space Telescope was engineered to withstand continual bombardment from these dust-sized particles moving at extreme velocities, to continue to generate groundbreaking science far into the future. "We have experienced 14 measurable micrometeoroid hits on our primary mirror, and are averaging one

First in line to receive data transmissions from the James Webb Space Telescope, a team of astronomers at the University of California, Irvine and other institutions is using the unprecedentedly clear observations to reveal the secret inner workings of galaxies. In a paper published in The Astrophysical Journal Letters, the researchers describe their examination of the nearby galaxy NGC 74

A few days after officially starting science operations, NASA's James Webb Space Telescope propelled astronomers into a realm of early galaxies, previously hidden beyond the grasp of all other telescopes until now. "Everything we see is new. Webb is showing us that there's a very rich universe beyond what we imagined," said Tommaso Treu of the University of California at Los Angeles, princ

The first galaxies may have formed far earlier than previously thought, according to observations from the James Webb Space Telescope that are reshaping astronomers' understanding of the early universe. Researchers using the powerful observatory have now published papers in the journal Astrophysical Journal Letters, documenting two exceptionally bright, exceptionally distant galaxies, based

Volcanic activity lasting hundreds to thousands of centuries and erupting massive amounts of material may have helped transform Venus from a temperate and wet world to the acidic hothouse it is today, a NASA paper suggests. The paper also discusses these "large igneous provinces" in Earth's history which caused several mass extinctions on our own planet millions of years ago. "By und

November 16, 2022, was a big day for all space industry fans. Artemis I, a first mission to the Moon after a break that lasted over 53 years, is finally launched. And while the eyes of millions were directed towards their screens to see the launch, only some people recognize the contributions of different countries to this achievement of humanity. In particular, the scientific contribution of Uk

NASA's Perseverance Mars rover has begun exploring an area the science team calls "Yori Pass" near the base of Jezero Crater's ancient river delta. They've been eager to explore the region for several months after spotting a rock similar to one Perseverance collected samples from in July. The feature is so tantalizing to the scientists because it is sandstone, which is composed of fine gra

The first privately developed Indian rocket lifted off into the upper reaches of the atmosphere on Friday, in another milestone in the country's push to become a major space power. The half-tonne Vikram-S rocket launched before midday local time and travelled in an arc, live footage from the Indian Space Research Organisation (ISRO) showed. It safely splashed down into the sea six minute

Mars is called the red planet. But once, it was actually blue and covered in water, bringing us closer to finding out if Mars had ever harboured life. Most researchers agree that there has been water on Mars, but just how much water is still debated. Now a study from the University of Copenhagen shows that some 4.5 billion years ago, there was enough water for the entire planet to be
