Boca Raton FL (SPX) Feb 15, 2023
About 40 percent of interior Alaska is underlain by ice-rich permafrost - permanently frozen grounds made up of soil, gravel and sand - bound together by ice. Certain conditions, such as climate warming, have intensified tundra wildfires which have profound implications for permafrost thaw.
Surface vegetation plays a dominant role in protecting permafrost from summer warmth, so any alterat

Japan aborts launch of 1st H3 rocket carrying defense sensor
Friday, 17 February 2023 06:07
The launch of a new flagship series H3 rocket carrying an observation satellite and an experimental infrared sensor that could detect missile launches was aborted Friday after its auxiliary booster engines failed to ignite, Japan's space agency said.
The countdown had started. The Japan Aerospace Exploration Agency livestream and TV footage showed white smoke billowing from the H3's main engine.

Mars is infamous for its intense dust storms, some of which kick up enough dust to be seen by telescopes on Earth.
When dust particles rub against each other, as they do in Martian dust storms, they can become electrified, transferring positive and negative electric charge in the same way as you build up static electricity if you shuffle across a carpet.

The James Webb Space Telescope - the most precise telescope ever built - was decisive in discovering the frozen forms of a long series of molecules, such as carbon dioxide, ammonia, methane, methanol and even more complex molecules, frozen out as ices on the surface of small dust grains.
The dust grains grow in size when being a part of the discs of gas and dust forming around young stars.
