Are chemical rockets or solar sails better to return resources from asteroids?
Monday, 09 January 2023 17:47 Write a comment
If and when we ever get an asteroid mining industry off the ground, one of the most important decisions to be made in the structure of any asteroid mining mission would be how to get the resources back to where all of our other infrastructure is—somewhere around the Earth.
That decision typically will focus on one of two propulsion methodologies—chemical rockets, such as those we already use to get us into space in the first place, or solar sails, which, while slower and unable to get us into orbit, don't require any fuel. So which propulsion methodology is better for these future missions? A study by researchers at the University of Glasgow looked at those two scenarios and came out with a clear-cut answer—solar sails.
When answering these types of theoretical questions, it is essential to impose limits on the answers. For example, billions of asteroids exist in the solar system, so it's more realistic to only look at those known as near-Earth asteroids (NEAs).

Sentinel-1 and AI uncover glacier crevasses
Monday, 09 January 2023 13:32 Write a comment
Scientists have developed a new Artificial Intelligence, or AI, technique using radar images from Europe’s Copernicus Sentinel-1 satellite mission, to reveal how the Thwaites Glacier Ice Tongue in West Antarctica is being damaged by squeezing and stretching as it flows from the middle of the continent to the coast. Being able to track fractures and crevasses in the ice beneath the overlying snow is key to better predicting the fate of floating ice tongues under climate change.

Historic UK rocket mission set for liftoff
Monday, 09 January 2023 12:22 Write a comment
Final preparations were under way Monday for the first rocket launch from UK soil, catapulting it into the "exclusive" club of nine nations able to send crafts into Earth's orbit.
A repurposed Boeing 747 carrying the 70-foot (21-meter) rocket containing nine satellites will take off from a spaceport in Cornwall, southwest England, at 2216 GMT.
The rocket will detach from the aircraft at a height of 35,000 feet over the Atlantic Ocean to the south of Ireland before later discharging the satellites.
The aircraft will then return to Spaceport Cornwall, a consortium that includes Virgin Orbit and the UK Space Agency, at Cornwall Airport Newquay.
The launch will be the first from UK soil. UK-produced satellites have previously had to be sent into orbit via foreign spaceports.
"Joining that really exclusive club of launch nations is so important because it gives us our own access to space... that we've never had before here in the UK," Spaceport Cornwall chief Melissa Thorpe told BBC television on Monday.
Over 2,000 people are expected to watch the launch named "Start Me Up" after the Rolling Stones song.
