Tidal stresses may be causing constant icequakes on Saturn's sixth largest moon Enceladus, a world of interest in the search for life beyond Earth, according to a new study. A better understanding of seismic activity could reveal what's under the moon's icy crust and provide clues to the habitability of its ocean. Enceladus is about 500 kilometers in diameter and almost entirely covered in

It's hard to miss a flashlight beam pointed straight at you. But that beam viewed from the side appears significantly dimmer. The same holds true for some cosmic objects: Like a flashlight, they radiate primarily in one direction, and they look dramatically different depending on whether the beam points away from Earth (and nearby space telescopes) or straight at it. New data from NASA's N

An unprecedented heat wave that started around June 26 smashed numerous all-time temperature records in the Pacific Northwest and western Canada. NASA's Atmospheric Infrared Sounder (AIRS), aboard the Aqua satellite, captured the progression of this slow-moving heat dome across the region from June 21 to 30. An animation of some of the AIRS data show surface air temperature anomalies - values ab

He's always dreamed of it, and in 2004 founded his own company to make it happen. On Sunday, billionaire Richard Branson will take off from a base in New Mexico aboard a Virgin Galactic vessel bound for the edge of space. The Briton is hoping to finally get the nascent space tourism industry off the ground - but also go one up on Jeff Bezos by winning the race to be the first person to

The 3.9 million pound grant from the UK Space Agency will support the development of Reaction Engines' ground-breaking SABRE technology, enabling low-carbon air-breathing space access propulsion technology to be applied more widely in the space sector and beyond. Science Minister Amanda Solloway and Transport Minister Rachel Maclean visited Reaction Engines at its site in Culham, Oxfordshi

In 1962 when America was going to the Moon, NASA established Kennedy Space Center in Florida as its Launch Operations Center. This month, the modernized multi-user spaceport marks its 59th anniversary while working to send Americans back to the Moon, helping grow the commercial space industry, and performing research that benefits humanity. The launch of NASA's Artemis I mission - slated t

Today, Mars is a planet of extremes - it's bitterly cold, has high radiation, and is bone-dry. But billions of years ago, Mars was home to lake systems that could have sustained microbial life. As the planet's climate changed, one such lake - in Mars' Gale Crater - slowly dried out. Scientists have new evidence that super salty water, or brines, seeped deep through the cracks, between grains of

Scientists know that the Earth was bombarded by huge impactors in distant time, but a new analysis suggest that the number of these impacts may have been x10 higher than previously thought. This translates into a barrage of collisions, similar in scale to that of the asteroid strike which wiped out the dinosaurs, on average every 15 million years between 2.5 and 3.5 billion years ago. Some

WASHINGTON — A growing number of spacecraft missions, as well as NASA’s Artemis program, are putting new pressures on the agency’s Deep Space Network of antennas that communicate with them.

In a July 7 presentation to the steering committee of the planetary science decadal survey, Brad Arnold, manager of the Deep Space Network (DSN) at the Jet Propulsion Laboratory, says that even with upgrades to the radio antennas at sites in Australia, California and Spain, the system can’t keep up with growing demand from missions.
