Using a space elevator to get resources from Ceres
Tuesday, 10 September 2024 16:47Here at UT, we've had several stories that describe the concept of a space elevator. They are designed to make it easier to get objects off Earth and into space. That, so far, has proven technically or economically infeasible, as no material is strong enough to support the structure passively, and it's too energy-intensive to support it actively.
However, it could be more viable on other worlds, such as the moon. But what about worlds farther afield? A student team from the University of Colorado at Colorado Springs looked at the use case of a space elevator on Ceres and found that it could be done with existing technology. The findings are published in the journal 2024 Regional Student Conferences.
Before we discuss why anyone would want to put a space elevator on Ceres, let's first examine the technologies that would make it possible. Every space elevator design has three different components: an anchor, a tether, and a counterweight.

Tuesday, 10 September 2024 12:24A daredevil billionaire rocketed back into orbit Tuesday, aiming to perform the first private spacewalk and venture farther than anyone since NASA's Apollo moonshots.
Unlike his previous chartered flight, tech entrepreneur Jared Isaacman shared the cost with SpaceX this time around, which included developing and testing brand new spacesuits to see how they'll hold up in the harsh vacuum.
If all goes as planned, it will be the first time private citizens conduct a spacewalk, but they won't venture away from the capsule. Considered one of the riskiest parts of spaceflight, spacewalks have been the sole realm of professional astronauts since the former Soviet Union popped open the hatch in 1965, closely followed by the U.S.
A look back at Sentinel-2C's ride into space on Vega
Tuesday, 10 September 2024 12:15
The third Copernicus Sentinel-2 satellite, Sentinel-2C, has launched aboard the last Vega rocket, flight VV24, from Europe’s Spaceport in French Guiana. The rocket lifted off on 5 September at 03:50 CEST (4 September 22:50 local time).
Sentinel-2C will provide high-resolution data that is essential to Copernicus – the Earth observation component of the European Union’s Space programme. Developed, built and operated by ESA, the Copernicus Sentinel-2 mission provides high-resolution optical imagery for a wide range of applications including land, water and atmospheric monitoring.
The mission is based on a constellation of two identical satellites flying in the

Space Team Europe for Vega: final liftoff
Tuesday, 10 September 2024 11:00Interviews with personnel that worked on the last Vega rocket, flight VV24, with Sentinel-2C onboard.
The third Copernicus Sentinel-2 satellite launched from Europe’s Spaceport in French Guiana aboard the final Vega rocket on 5 September at 03:50 CEST (4 September 22:50 local time).
After a successful launch, Sentinel-2C separated from its Vega rocket at approximately 04:48 CEST. Around 14 minutes later, at 05:02 CEST, ESA’s ESOC mission operations centre in Darmstadt, Germany, received the all-important first signals from the satellite indicating that it had safely arrived in orbit.

The 2024 Global Methane Budget reveals alarming trends
Tuesday, 10 September 2024 08:00The Global Methane Budget 2024 paints a troubling picture of the current state of global methane emissions. The new report reveals that human activities are now responsible for at least two-thirds of global methane emissions.
This marks a significant increase in human-produced methane sources over the past two decades, with emissions rising by 20%, with the fastest rise occurring over the last five years.
