What lies beneath the far side of the moon?
Thursday, 05 August 2021 13:50 Write a comment
A new technique for processing lunar radar data has allowed scientists to see what lies beneath the surface of the moon in the clearest ever detail.
In a study led by the University of Aberdeen, a team of researchers discovered multiple layers of soil that lie directly beneath an area on the far side of the moon's surface, overturning an existing theory of a single deep layer in the same area.
The area studied was the landing site of the Chang'E-4 spacecraft mission—the first to the far side of the moon.
Analysis of radar data captured by the mission's rover, Yutu-2, had suggested the existence of a single soil layer in the moon's regolith (subsurface). However, the data did not indicate the existence of different layers of soil, which were transparent to electromagnetic waves due to the smooth boundaries between them.
By developing a new method of processing the data captured by Yutu-2, which uses the shape of radar signatures of buried rocks and boulders to infer the properties of surrounding lunar soil and detect previously unseen layers with smooth boundaries, scientists were able to detect four distinct layers of soil, stacked to a depth of 12 meters.
Op-ed | China’s Success in Space Calls for Caution in Pursuing a New Treaty for Outer Space

Any decision by the U.S. to pursue a new treaty for outer space should take into account whether the worldview espoused by the U.S. and its allies is solidified in international law and has the political will to prevail over attempts by China and its client states to subvert an enacted treaty.
Lunar samples solve mystery of the moon's supposed magnetic shield
Thursday, 05 August 2021 12:05 Write a comment
In 2024, a new age of space exploration will begin when NASA sends astronauts to the moon as part of their Artemis mission, a follow-up to the Apollo missions of the 1960s and 1970s.
Some of the biggest questions that scientists hope to explore include determining what resources are found in the moon's soil and how those resources might be used to sustain life.
In a paper published in the journal Science Advances, researchers at the University of Rochester, leading a team of colleagues at seven other institutions, report their findings on a major factor that influences the types of resources that may be found on the moon: whether or not the moon has had a long-lived magnetic shield at any point in its 4.53 billion-year history.

Satellites reveal how forests increase cloud and cool climate
Thursday, 05 August 2021 07:45 Write a comment
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.
Helicopter scouts ridge area for Perseverance

Ask any space explorer, and they'll have a favorite photo or two from their mission. For Kevin Hand, a scientist at NASA's Jet Propulsion Laboratory in Southern California and co-lead of the Perseverance rover's first science campaign, his latest favorite is a 3D image of low-lying wrinkles in the surface of Jezero Crater. The science team calls this area "Raised Ridges." NASA's Ingenuity Mars H North-By-Northwest for Ingenuity's 11th Flight

Sitting more than five times the distance from the Sun as Earth, Jupiter is not expected to be particularly warm. 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. Instead, the measured value soars to around 800 degrees Fahrenheit or 426 Celsius. The source of this extra he NASA launches x-ray spectrometer mission to probe mysteries of solar corona
