About 17 years ago, J. Martin Laming, an astrophysicist at the U.S. Naval Research Laboratory, theorized why the chemical composition of the Sun's tenuous outermost layer differs from that lower down. His theory has recently been validated by combined observations of the Sun's magnetic waves from the Earth and from space.

Italian ESA astronaut Samantha Cristoforetti poses in the Cupola module of the International Space Station with two 100-day patches to mark her 200th day in space. She is now set to return to her ‘home away from home’ for even more days in space.
Samantha first flew to the International Space Station on a Soyuz spacecraft in 2014 for a mission known as ‘Futura’. Her second flight follows the second missions of her fellow 2009 astronaut classmates Alexander Gerst in 2018, Luca Parmitano in 2019 and Thomas Pesquet in 2021. It could also see a direct on-Station handover with Matthias
NASA's James Webb Space Telescope completes final functional tests to prepare for launch
Monday, 01 March 2021 13:10 Write a comment
February marked significant progress for NASA's James Webb Space Telescope, which completed its final functional performance tests at Northrop Grumman in Redondo Beach, California. Testing teams successfully completed two important milestones that confirmed the observatory's internal electronics are all functioning as intended, and that the spacecraft and its four scientific instruments can send and receive data properly through the same network they will use in space. These milestones move Webb closer to being ready to launch in October.
These tests are known as the comprehensive systems test, which took place at Northrop Grumman, and the ground segment test, which took place in collaboration with the Space Telescope Science Institute in Baltimore.
