On Monday, Jan. 24, engineers plan to instruct NASA's James Webb Space Telescope to complete a final correction burn that will place it into its desired orbit, nearly 1 million miles away from the Earth at what is called the second Sun-Earth Lagrange point, or "L2" for short. Mathematically, Lagrange points are solutions to what …

Payloads: AstroPi: The crew adjusted the back focus of the AstroPi 5 mm camera lens and set the aperture to 8.  This was performed for the AstroPi unit currently mounted in the Node 2 nadir window.  The current Astro Pis are a very recent upgrade and replacement for the original Astro Pi hardware that flew …

The five astronauts representing the Expedition 66 crew had an off-duty day on Friday while the two cosmonauts continued their post-spacewalk activities.

A U.S. resupply ship will wait at least one extra day to undock from the International Space Station while being packed with critical research samples for return to Earth. Meanwhile, two Expedition 66 cosmonauts are cleaning up following a spacewalk to activate a Russian docking module. A forecast of inclement weather has caused a postponement …

Editor's Note: This post was updated to clarify the strength vs. stiffness of beryllium. Last week, the Webb team began moving the observatory's individual mirror segments out of their launch positions. Today, we hear from Erin Wolf, Webb program manager at Ball Aerospace, about the completion of that process: "Today, the James Webb Space Telescope …
