NASA astronaut Chris Williams is gearing up for a spacewalk on June 30, along with fellow astronaut Jessica Meir, to replace a malfunctioning wrist joint on the Canadarm2 robotic arm. This crucial maintenance task will ensure the continued smooth operation of the International Space Station.
Mapping Earth's Observations
NASA's Earth-observing satellites track a vast range of phenomena, from aerosols in the atmosphere to land-cover shifts over decades. This data informs science, policy, agriculture, and climate research worldwide. Betsy Ford, a key figure in NASA's Earth Science Division, emphasizes the significance of this data, saying, "It reaches more people than most realize. The farmers who are growing your food are using this data."
An Island of Calm at the Galactic Heart
Astronomers have discovered a rare island of calm at the heart of the Milky Way, where stars can form despite the chaotic environment. This finding challenges our understanding of star formation in extreme conditions.
Two Planets Lighter Than Candy Floss
The discovery of TOI-791 b and TOI-791 c, two planets with densities lower than candy floss, has left astronomers stunned. These "super-puff" planets are roughly the size of Jupiter but contain almost nothing by comparison.
Key Facts
- Who: Chris Williams and Jessica Meir (NASA astronauts)
- What: Spacewalk to replace a malfunctioning wrist joint on the Canadarm2 robotic arm
What to Watch
