What's covered

Temperate Exoplanet TOI-199b

A gas giant three hundred and thirty light-years away just upended what we thought we knew about how planets form. JWST has completed the first detailed spectroscopic study of TOI-199b, a Saturn-sized exoplanet sitting in a temperature range that almost no known gas giant occupies.

Mars: Honeycombs and Ancient Water

Mars produced two separate results worth keeping in frame together. Curiosity has identified the largest polygonal fracture field it has ever observed, in a region called Valle Grande.

ISS Spacewalks and Deorbit Prep

Closer to home, NASA has scheduled three ISS spacewalks for August, on the sixth, thirteenth, and twenty-fifth. The work covers power system upgrades, a communications antenna replacement, and infrastructure preparation.
