More lunar missions means more space junk around the Moon—two astronomers are building a catalog to track the trash
Scientists and government agencies have been worried about the space junk surrounding Earth for decades. But humanity's starry ambitions are farther reaching than the space just around Earth. Ever since the 1960s with the launch of the Apollo program and the emergence of the space race between the U.S. and Soviet Union, people have been leaving trash around the moon, too.
Today, experts estimate that there are a few dozen pieces of space junk like spent rocket bodies, defunct satellites and mission-related debris orbiting in cislunar space—the space between Earth and the moon and the area around the moon. While this isn't yet a large amount of junk, astronomers have very little information about where these pieces of space debris are, let alone what they are and how they got there.
Sentinel-4 set to join next weather satellite
Copernicus Sentinel-4, which is set to play a key role in monitoring air quality over Europe, is ready to be fitted to its host, the first Meteosat Third Generation Sounder weather satellite.
Copernicus Sentinel-4 is a state-of-the-art ultraviolet, visible, near-infrared spectrometer instrument that has been developed to deliver hourly high-resolution measurements of trace gases such as nitrogen dioxide, ozone, sulphur dioxide and formaldehyde, as well as aerosols.
Galileo signal component tested for Internet of Things use
One of Europe's Galileo satellites has been reconfigured to emit a new signal component optimised to serve low-end receiver devices and Internet of Things applications.
Spanish lagoon used to better understand wet-to-dry transition of Mars
In the ongoing search for signs of life on Mars, a new study proposes focusing on "time-resolved analogs" - dynamic and similar Earth environments where changes can be analyzed over many years.
Alberto Fairen, visiting scientist of astronomy at Cornell University, led an investigation in the extremely salty Tirez lagoon in central Spain, which had experienced alternating dry and wet period Bringing more power to Space Station
A new cargo mission stands ready to launch early Thursday and dock to the International Space Station two days later. Meanwhile, the Expedition 68 crew switched roles between space scientists and orbital plumbers on Wednesday promoting advanced knowledge and maintaining life support systems.

Concordia researchers have developed a new technique that can help create high-quality, accurate 3D models of large-scale landscapes - essentially, digital replicas of the real world. While more work is required before the researchers achieve their goal, they recently outlined their new automated method in the Nature journal Scientific Reports.
