Without a protective atmosphere, space-exposed surfaces of airless Solar System bodies gradually experience an alteration in composition, structure and optical properties through a collective process called space weathering.
a , The grain C0105–03004800 was collected at the second touchdown site. It is composed of two parts showing different types of space weathering: a frothy layer and a smooth layer.
Local News: NASA Ambassador: Her lessons often are out of this world (12/19/22) | Le Mars Daily ...
LE MARS � Students in Meredith Clymer�s fifth- and sixth-grade science classroom often learn things that are out of this world.
Clymer, a resident of Sioux Center who teaches sixth-grade language arts at Gehlen Catholic School in Le Mars, has been a Nebraska Space Ambassador since 2010 when she was a preservice teacher.
How magnetic waves interact with Earth's bubble
They used a computer model , Vlasiator, to simulate the physical processes at play in the transmission of these waves, finding waves on the other side of the shock with almost identical properties as in the foreshock.
Co-author Dr. Daniel Verscharen (UCL Mullard Space Science Laboratory), who has world-leading expertise in analyzing plasma waves and whose code was used to interpret the MMS data, said, "Shock waves in plasma are much more difficult to understand than when they occur in air.
ESA - One year ago, a perfect launch for the James Webb Space Telescope
The voice counted backwards in French from ten to one, then announced, "Décollage" – lift-off. The 15-year-long collaboration between NASA, ESA and the Canadian Space Agency had just entered its most critical phase: the launch itself.
"On the day of launch, the pressure was extremely high.
Ohio Student Has Career Liftoff with NASA Scholarship | Cedarville University
When people hear the word "NASA," they probably think of space and rockets. But for Tara Keller, a molecular biology major at Cedarville University, her interest in biology and health care landed her a research opportunity with the well-renowned organization.
NASA is partnering with the Ohio Aerospace Institute to sponsor college students conducting research that would be applicable to NASA's field of study. Keller was chosen as one of the recipients.

Unexpected long-term variability in Jupiter's tropospheric temperatures | Nature Astronomy
An essential component of planetary climatology is knowledge of the tropospheric temperature field and its variability. Previous studies of Jupiter hinted at non-seasonal periodic behaviour, as well as the presence of a dynamical relationship between tropospheric and stratospheric temperatures.
