SpaceX has temporarily grounded its workhorse Falcon 9 rocket, which is slated to launch four astronauts just eight days from now. A Falcon 9 delivered 25 of SpaceX’s Starlink satellites into low Earth orbit (LEO) as planned on Monday (Feb. 2). But, after deploying the payloads, the rocket’s upper stage failed to perform its deorbit
NASA has delayed the launch of its Artemis II lunar fly-by mission by at least a month. Testing of the rocket and capsule, shown here on the launch pad at the Kennedy Space Center in Florida Sunday, revealed a number of issues. The launch, with four astronauts, would be the first crewed mission to the
Since the dawn of the quantum era, perhaps no question has loomed larger in the minds of theoretical physicists than just what, exactly, the nature of reality is. Are quantum objects real, with well-defined positions and momenta, even in the absence of an observation or measurement to determine them? Out of all the ways to
NASA’s Space Launch System rocket stands atop pad 39B at the Kennedy Space Center. After working around a hydrogen leak at the base of the rocket, engineers spent the day Monday pumping more than 750,000 gallons of supercold liquid oxygen and hydrogen fuel into the 32-story-tall launcher in a dress rehearsal countdown. How the leak
Article summary The RNA world hypothesis proposes that early life relied on RNA alone to store genetic information and catalyse chemical reactions, resolving the apparent chicken‑and‑egg problem posed by the modern DNA–RNA–protein system. The discovery that the ribosome is a ribozyme, along with the versatility of RNA, provides strong evidence that RNA pre‑dated
The western US is a geologists’ dream, home to the Rocky Mountains, the Grand Canyon, active volcanoes and striking sandstone arches. But one landform simply doesn’t make sense. Rivers normally flow around barriers. The Danube river, for example, flows between the Alps and the Carpathians, twisting and turning to avoid the mountains. But in north-western

The Sun has unleashed a quartet of strong solar flares, which could herald a wild week of space weather. It all kicked off at 12:33 UTC on February 1, when the Sun fired off an X1.0 flare. About 11 hours later, at 23:37 UTC, a massive eruption occurred with an X8.1 flare. Two more followed
WASHINGTON — SpaceX is pausing Falcon 9 launches after an issue with the rocket’s upper stage encountered at the end of a launch Feb. 2. A Falcon 9 lifted off from Vandenberg Space Force Base in California at 10:47 a.m. Eastern. The rocket’s upper stage deployed its payload of 25 Starlink satellites into low Earth
