Measurements from the Copernicus Sentinel-5P satellite show that this year’s ozone hole over Antarctica is one of the biggest on record. The hole, which is what scientists call an ‘ozone depleting area,’ reached a size of 26 million sq km on 16 September 2023. This is roughly three times the size of Brazil.

A briefcase-sized CubeSat being flown on Europe’s next Vega launcher this week will gather 340 km wide views of Earth’s vegetation growth, employing a spectral imager originally designed for ESA’s decade-in-flight Proba-V.

Computing is at an inflection point. Moore's Law, which predicts that the number of transistors on an electronic chip will double each year, is slowing down due to the physical limits of fitting more transistors on affordable microchips. These increases in computer power are slowing down as the demand grows for high-performance computers that can support increasingly complex artificial intellige

In the future, quantum computers may be able to solve problems that are far too complex for today's most powerful supercomputers. To realize this promise, quantum versions of error correction codes must be able to account for computational errors faster than they occur. However, today's quantum computers are not yet robust enough to realize such error correction at commercially relevant sc

Superbolts are more likely to strike the closer a storm cloud's electrical charging zone is to the land or ocean's surface, a new study finds. These conditions are responsible for superbolt "hotspots" above some oceans and tall mountains. Superbolts make up less than 1% of total lightning, but when they do strike, they pack a powerful punch. While the average lightning strike contains arou

NASA has selected seven companies to provide commercial data in support of the agency's Earth science research. The Commercial Smallsat Data Acquisition Program will acquire Earth observation data and related services from commercial sources for NASA. This fixed-price, indefinite-delivery/indefinite-quantity, multiple-award contract will be effective for a period of five years with an opti

NASA will begin the critical testing of updated engines for its Space Launch System rocket on Thursday, starting with turning power levels up to 111%, as the space agency prepares for future Artemis missions to the Moon. The assessments mark the final round of certification testing ahead of production of the RS-25 engines for the SLS rocket, NASA said in a statement. The engines are exp

The Chang'e 8 robotic probe, the third to be placed on the moon during China's next lunar exploration endeavor, is open to foreign science payloads, according to the China National Space Administration. Wang Qiong, deputy head designer of the Chang'e 8 mission, said on Monday at the ongoing 74th International Astronautical Congress in Baku - capital of Azerbaijan - that there will be 200 k

Following the failure of the Vega-C launch (VV22) in December 2022, an Independent Enquiry Commission drew several conclusions and made recommendations to ensure a reliable return to flight and a robust exploitation. One of the recommendations was to implement a (delta-)qualification of the nozzle with a new Carbon-Carbon throat insert material different from that previously used on the Zefiro40

MIURA 1 launch campaign kicks off. PLD Space has successfully concluded the two pre-launch tests of the first flight unit of the Spanish launcher, specifically the umbilical cable tests and the Wet Dress Rehearsal (WDR). The positive results obtained during these tests effectively give the green light to the flight mission of the suborbital microlauncher. The launch will take place this Oc
