Companies involved with commercial activities on the International Space Station or planning their own space stations may face a new competitor in China’s new space station.
Satellites reveal how forests increase cloud and cool climate
Thursday, 05 August 2021 07:45
Forests are not only key to moderating our climate by sequestering atmospheric carbon, but they also create a cooling effect by increasing low-level cloud. A first global assessment using satellite observations has shown that for two-thirds of the world, afforestation increases low-level cloud cover, with the effect being strongest over evergreen needleleaf forest.

We're heading northwest for the 11th flight of NASA's Ingenuity Mars Helicopter, which will happen no earlier than Wednesday night, Aug. 4. The mission profile is designed to stay ahead of the rover - supporting its future science goals in the "South Seitah" region, where it will be able to gather aerial imagery in support of future Perseverance Mars rover surface operations in the area.

Based on the amount of sunlight received, the average temperature in the planet's upper atmosphere should be about minus 100 degrees Fahrenheit or a chilly minus 73 Celsius.

A lot of power means a lot of heat. NASA's future missions to explore the Moon and Mars will require enormous amounts of electrical power and hardware to support astronauts and drive new technologies. This increase in power, however, also increases the amount of heat generated-and then that heat needs to be removed so all the spacecraft systems can function.

When Hurricane Irma hit southern Florida in September of 2017, the storm buffeted coastal mangrove forests with winds over 116 mph - strong enough to rip off leaves, break branches, and snap tree trunks in half. Of the mangrove forest damaged by Hurricane Irma, about 83% recovered after the first year. But the rest didn't, leaving scientists wondering why some trees didn't bounce back.

Virtually all oxygen on Earth was and is produced by photosynthesis, which was invented by tiny organisms, the cyanobacteria, when our planet was still a rather uninhabitable place. Cyanobacteria evolved more than 2.4 billion years ago, but Earth only slowly transformed to the oxygen-rich planet we know today.

A shortage of semiconductors has sent shockwaves through the global economy, squeezing supplies of everything from cars to headphones.
The dearth of chips has exposed the modern world's reliance on these miniscule components, the basic building blocks of computers which allow electronic devices to process data. Why is the shortage happening, and what can be done about it?
