Nuclear strategies tested at Sandia could avert asteroid disaster
Write a comment
Sandia National Laboratories is exploring a coordinated nuclear response to deflect potentially catastrophic asteroids, according to physicist Nathan Moore. His team is using Sandia's Z machine-the world's most powerful pulsed-power facility-to simulate asteroid deflection scenarios and gather critical data on how asteroids of different compositions respond to such methods.
"To most people A Striped Surprise

Last week, team scientists and the internet alike were amazed when Perseverance spotted a black-and-white striped rock unlike any seen on Mars before. Is this a sign of exciting discoveries to come?
It has now nearly been a month since the rover began its climb up the steep slopes leading to the crater rim, on the hunt for ancient rocks that could teach us about early Martian history. Whil New Glenn second stage completes successful hotfire test ahead of November launch

Blue Origin's New Glenn second stage (GS2) successfully completed a critical hotfire test Tuesday, marking a key step toward its first flight, set for November from Cape Canaveral's Launch Complex 36. The NG-1 mission will carry Blue Ring technology as its first payload.
The 15-second hotfire test was the first time the vehicle operated as a fully integrated system. This test was conducted China launches eight satellites using Smart Dragon 3 rocket

On Tuesday morning, China launched a Smart Dragon 3 carrier rocket from the coast of Haiyang in Shandong province, successfully deploying eight satellites into space. According to the China Academy of Launch Vehicle Technology, the satellites were placed into their designated orbital positions shortly after the rocket's launch at 10:31 am from a launch service ship. This marks the fourth sea-bas Draco mission made for destruction

Over the nearly 70 years of spaceflight, about 10 000 intact satellites and rocket bodies have reentered the atmosphere with many more to follow. Yet for such a ubiquitous event, we still lack a clear view on what actually happens to a satellite during its fiery last moments.
ESA is preparing the Destructive Reentry Assessment Container Object (Draco) mission that will collect unique measurements during an actual reentry and breakup of a satellite from the inside. A capsule especially designed to survive the destruction will transmit the valuable telemetry shortly after.

Research abounds at the International Space Station
Write a comment
At the International Space station, researchers are making strides in everything from Earth science to chemical properties. Here's what they're up to and why it matters.
Recently, researchers have found that eddies, or swirling wind patterns, increased moisture evaporation in an alfalfa field. A better understanding of the complex exchange of water and heat between the ground and atmosphere could improve remote sensing products and their use in agricultural water management.
The station's ECOSTRESS instrument takes high-resolution thermal infrared measurements of Earth's surface that provide data on changes in water availability, vegetation water stress, and agricultural water use. Researchers use observations from the USGS Landsat 8 and 9 satellites and ECOSTRESS to validate climate models and update data on Earth's surface energy (the amount of energy absorbed from the sun and radiated back into the atmosphere).

LUNA infographics New study suggests Earth's mantle is more chemically uniform than previously thought
Write a comment
Lavas from volcanic hotspots around the world, such as Hawaii, Samoa, and Iceland, likely come from a chemically uniform reservoir in Earth's mantle, according to new research published in 'Nature Geoscience'. The study challenges the long-standing belief that the mantle contains chemically distinct reservoirs.
The research suggests that Earth's mantle is more homogeneous than scientists h Bridging the heavens and Earth

When Jared Bryan talks about his seismology research, it's with a natural finesse. He's a fifth-year PhD student working with MIT Assistant Professor William Frank on seismology research, drawn in by the lab's combination of GPS observations, satellites, and seismic station data to understand the underlying physics of earthquakes. He has no trouble talking about seismic velocity in fault zones o
