The part of the atmosphere closest to the planet is the hardest to measure from space due to the volume of gases above it. Studying Earth's planetary boundary layer, or PBL, will enable scientists to better understand the interaction between Earth's surface and weather and how that evolves in a global, changing climate.

As the main freshwater resource on Earth's surface, lakes play an important role in maintaining ecosystem stability and the sustainable development of human society.
However, it's been difficult to evaluate changes in global lake-water volume across space and time due to data problems. Specifically, ground-monitoring data have not been sufficiently representative of all lakes, and traditio

New U.S. sanctions on Russia will encompass Russia's space agency, Roscosmos, according to a speech U.S. President Joe Biden gave on Feb. 24, 2022.
In response to these sanctions, the head of Roscosmos on the same day posted a tweet saying, among other things, "If you block cooperation with us, who will save the ISS from an uncontrolled deorbit and fall into the United States or Europe?"

In 2002, the European Space Agency launched Envisat, the largest civilian satellite (at the time) to go to low Earth orbit (LEO). For a decade, it observed our planet and sent back valuable data on Earth's climate, tracking the decline of Arctic sea ice and more, until it went dark in 2012.

Durham University astronomer collaborating with a team of international scientists have mapped more than a quarter of the northern sky using the Low Frequency Array (LOFAR), a pan-European radio telescope.
The map reveals an astonishingly detailed radio image of more than 4.4 million objects and a very dynamic picture of our Universe, which now has been made public for the first time.
