Sand dunes are a familiar sight along beaches and in deserts. While we know how regular sand dunes are formed, much less is known about dunes made of snow. In a new study, scientists have analysed the vast snow dunes across Antarctica – reshaping our understanding of the continent's surface dynamics.
This research sheds light on the unexplored world of Antarctic snow dunes, offering a fresh perspective on the complex interactions between wind, snow and climate in one of Earth's harshest environments.

New mission to create total solar eclipses in space
Monday, 30 September 2024 15:52 Write a comment
A UK team of researchers including UCL's Professor Lucie Green are working on the launch of a spacecraft mission that will allow us to view the sun's atmosphere in more detail than ever before.
The proposed MESOM mission will enable researchers to study the conditions that create solar storms, leading to improvements in forecasts of space weather on Earth.
The MESOM spacecraft will fly on a peculiar trajectory enabled by the gravitational attraction of the Earth, the sun and the moon, and will use the shadow of the moon to re-create a total solar eclipse in space once every lunar month lasting almost 50 minutes.
Total solar eclipses seen from Earth are much shorter and only last between 10 seconds and 7.5 minutes, with the annular solar eclipse in the Southern Hemisphere this Wednesday 2 October expected to last around seven minutes.
Creating a longer eclipse in space will enable the MESOM team to take high-quality images and measurements of the sun's corona, filling gaps in existing understanding of the physical processes taking place in the solar atmosphere that lead to space weather.
SpaceX docks at ISS to take Starliner astronauts home next year

The SpaceX crew that will ferry back in February two astronauts stranded on the International Space Station docked with the orbiting laboratory on Sunday, a live stream of the mission showed.
The Falcon 9 rocket took off at 1:17 pm (1717 GMT) from Cape Canaveral, Florida on Saturday, with the Crew-9 mission aboard a Dragon spacecraft making contact with the ISS at 5:30 pm Sunday.
After d CubeSats, the tiniest of satellites, are changing the way we explore the solar system
Monday, 30 September 2024 14:10 Write a comment
Most CubeSats weigh less than a bowling ball, and some are small enough to hold in your hand. But the impact these instruments are having on space exploration is gigantic. CubeSats—miniature, agile and cheap satellites—are revolutionizing how scientists study the cosmos.
A standard-size CubeSat is tiny, about 4 pounds (roughly 2 kilograms). Some are larger, maybe four times the standard size, but others are no more than a pound.
As a professor of electrical and computer engineering who works with new space technologies, I can tell you that CubeSats are a simpler and far less costly way to reach other worlds.
Rather than carry many instruments with a vast array of purposes, these Lilliputian-size satellites typically focus on a single, specific scientific goal—whether discovering exoplanets or measuring the size of an asteroid. They are affordable throughout the space community, even to small startup, private companies and university laboratories.

ESA has released its new Earth Observation Science Strategy, Earth Science in Action for Tomorrow’s World. Responding to the escalating threats from climate change, biodiversity loss, pollution and extreme weather and the need to take action to address these threats, this forward-looking strategy outlines a bold vision for Earth science through to 2040.
SpaceX shuts down launches after problem with Crew-9 mission's 2nd stage
Monday, 30 September 2024 10:30 Write a comment
SpaceX celebrated the first human spaceflight from its Cape Canaveral launch site on Saturday, and while the two humans aboard the Crew Dragon Freedom are safely on their way to the International Space Station, a problem arose with the rocket's second stage that prompted the company to shut down future launches for now.
"After today's successful launch of Crew-9, Falcon 9's second stage was disposed in the ocean as planned, but experienced an off-nominal deorbit burn," SpaceX posted on X. "As a result, the second stage safely landed in the ocean, but outside of the targeted area. We will resume launching after we better understand [the] root cause."
The first victim of the shutdown was a planned launch Sunday from California of a Falcon 9 with a plan to send up the OneWeb Launch 20 mission for EutelsatGroup.
The Federal Aviation Administration still has that launch on its operations plan advisory for as early as Oct. 1, but the last two times SpaceX had an "off-nominal" issue with a Falcon 9 launch, the FAA had grounded the rocket.
The most recent was a fiery landing of a Falcon 9's first-stage booster last month during a Starlink mission.
