Iodine thruster could help clear space junk
A commercial nanosat called SpaceTy Beihangkongshi-1 – launched November 2020 – has successfully used an iodine thruster to change its orbit around Earth. This new thruster might help clear space junk by steering small satellites, at the end of their missions, back into Earth’s atmosphere where they’d burn up.
Wet and wild: There’s lots of water in the world’s most explosive volcano
(Washington University in St. Louis) Conditions inside the Shiveluch volcano include roughly 10%-14% water by weight (wt%), according to research from Washington University in St. Louis. Most volcanoes have less than 1% water. For subduction zone volcanoes, the average is usually 4%, rarely exceeding 8 wt%, which is considered superhydrous.
Squeezing a rock-star material could make it stable enough for solar cells
A promising lead halide perovskite is great at converting sunlight to electricity, but it breaks down at room temperature. Now scientists have discovered how to stabilize it with pressure from a diamond anvil cell. The required pressure is well within the reach of industrial manufacturing requirements.
NASA âmoleâsâ attempts to dig into Mars failed. Whatâs next?
The mission team for NASA’s InSight lander called off its attempts to try to dig deeper into Mars with the heat probe known as “the mole.” Meanwhile, the rest of the mission gained an extension to December 2022.
World’s largest lakes reveal climate change trends
Sixteen years of remote sensing data reveals that in Earth’s largest freshwater lakes, climate change influences carbon fixation trends.

Antarctica: The ocean cools at the surface but warms up at depth
Scientists have concluded that the slight cooling observed at the surface of the Southern Ocean hides a rapid and marked warming of the waters, to a depth of up to 800 meters. These results were obtained thanks to unique data acquired over the past 25 years.
Climate-related species extinction possibly mitigated by newly discovered effect
Changes in climate that occur over short periods of time influence biodiversity. For a realistic assessment of these effects, it is necessary to also consider previous temperature trends going far back into Earth’s history.

There Are 300 Million Potentially Habitable Planets in the Milky Way, NASA Reports
Since astronomers confirmed the presence of planets beyond our solar system, called exoplanets, humanity has wondered how many could harbor life. Now, we’re one step closer to finding an answer. According to new research using data from NASA’s retired planet-hunting mission, the Kepler space telescope, about half the stars similar in temperature to our Sun […]
