National lab takes its radiation expertise to space
Tuesday, 10 September 2024 20:05
An experiment designed to answer questions about the radiation environment for manned space missions was launched from Kennedy Space Center today.
For the five-day mission, experiments from the Department of Energy's Pacific Northwest National Laboratory and several other institutions will circle the Earth 435 miles above—nearly twice as high as the International Space Station. Before settling in at that altitude, Polaris Dawn will reach 870 miles, the highest that any person has been since NASA's Apollo program several decades ago.
Who is on SpaceX's historic private spacewalk mission?
Tuesday, 10 September 2024 19:30
Four US civilians are set to attempt the first-ever private spacewalk on Thursday—a risky endeavor usually reserved for trained astronauts from government agencies.
The ambitious mission, dubbed Polaris Dawn, is being carried out on a SpaceX capsule that launched early Tuesday from Florida.
Who are the select few to pioneer this new chapter of space exploration?
Jared Isaacman, billionaire
The driving force behind the mission is Jared Isaacman, a billionaire who serves as mission commander.
The 41-year-old American from Pennsylvania is the CEO of the digital finance company Shift4 Payments, which he founded in his family's basement when he was only 16.
Isaacman is a seasoned pilot who is qualified to fly military aircraft and holds several world records.
He had previously gone into space in 2021 as part of another SpaceX mission he chartered, Inspiration4, which was the first orbital spacecraft to feature no professional astronauts.

NASA's latest climate-focused mission has commenced its study of far-infrared radiation emitted by the Arctic and Antarctic regions. The data collected by the Polar Radiant Energy in the Far-Infrared Experiment (PREFIRE) will play a critical role in predicting the impact of climate change on Earth's ice, oceans, and weather, aiding global efforts to prepare for environmental shifts.
PREFIR Satellites unlock new insights into aerosol layer heights over oceans

A new study has shown that NASA's PACE satellite, equipped with the Ocean Color Instrument (OCI), can precisely measure the height of aerosol layers above ocean surfaces. This capability is essential for improving our understanding of how aerosols influence weather patterns and climate and is a major advancement in atmospheric correction techniques used in satellite-based ocean color monitoring.

Using a space elevator to get resources from Ceres
Tuesday, 10 September 2024 16:47
Here 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.
