On Wednesday, Jan. 15, NASA astronauts Jessica Meir and Christina Koch will step outside of the International Space Station into the vacuum of space together. The duo will replace old nickel-hydrogen batteries with newer, more powerful lithium-ion batteries to continue upgrading station power systems on the Port-6 truss structure. The spacewalk is scheduled to begin at 6:50 a.m. EST and last about six-and-a-half hours. youtube.com/watch?v=84CRZYioFR

The first class of astronauts in the Artemis Generation have graduated after two years of astronaut training. These 13 men and women from both the U.S. and Canada are now ready to travel to the International Space Station, the Moon and beyond.

There’s an adage that it’s not healthy to skip meals. Apparently, a supermassive black hole in the center of a galaxy millions of light years away has gotten the message. nasa.gov/mission_pages/chandra

Thousands of computers at NASA's Goddard Space Flight Center are tasked with running sophisticated climate models to predict Earth’s future climate. Collectively known as NASA's Discover supercomputer, they’re now also sussing out whether any of the more than 4,000 curiously weird planets beyond our solar system could support life. nasa.gov/feature/goddard/2020/

NASA's Kepler spacecraft was designed to find exoplanets by looking for stars that dim as a planet crosses the star's face. Fortuitously, the same design makes it ideal for spotting other objects that brighten or dim over time. A new search of Kepler archival data has uncovered an unusual super-outburst from a previously unknown dwarf nova. nasa.gov/feature/goddard/2020/

Astronomers have discovered a third planet in the Kepler-47 system, securing the system’s title as the most interesting of the binary-star worlds. nasa.gov/feature/discovery-ale

After nine years in deep space collecting data that indicate our sky to be filled with billions of hidden planets – more planets even than stars – NASA’s Kepler space telescope has run out of fuel needed for further science operations. nasa.gov/press-release/nasa-re

The week of Jan. 20, crew members aboard the International Space Station worked on a number of scientific investigations, including studies of using probiotics to improve immune health and of complex plasmas, as well as measurements of black holes and Earth’s upper atmosphere. nasa.gov/mission_pages/station

The Global Ecosystem Dynamics Investigation mission (GEDI) made their firstdata available to the public in January 2020, providing access to morecomprehensive forest data than ever before. nasa.gov/feature/goddard/2020/

Scientific investigations under way on the International Space Station the week of Jan. 13 included research on flame spread, the spacecraft food menu and how human bodies adapt to space. nasa.gov/mission_pages/station

The week of Jan. 6, the crew of the International Space Station conducted scientific investigations including research on protein crystal growth, biofilm control and improving the intestinal microbiome of crew members. nasa.gov/mission_pages/station

The crew of the International Space Station conducted a variety of scientific investigations the week of Dec. 30, including research on fire in contained spaces and monitoring equipment with robots. nasa.gov/mission_pages/station
