The Moon has impeccable timing.

October's full Moon rises tonight, bringing a little moonlit magic to the start of Halloween week.

The Moon reaches peak illumination at 12:12am ET (0412 UTC) on Oct. 26. Don't forget to look up!
The full Moon of March 2025 glows against a deep blue evening sky, framed by the dark, twisting branches of a leafless tree. Photographed rising over New Orleans, home to NASA's Michoud Assembly Facility, on March 13, 2025, this full Moon coincided with a total lunar eclipse. Credit: NASA/Eric Bordelon

To prepare for NASA’s Artemis IV mission to land astronauts on the lunar surface, SpaceX and Blue Origin have updated their concepts of operations for its landers.

These landers — Starship and Blue Moon — have concepts of operations different from one another. More below ⬇️
Seen from behind the Moon during the Artemis II mission, the Moon and Earth align in the same frame, each partially illuminated by the Sun. The Moon’s surface appears in sharp detail in the foreground, while Earth sits much farther away, smaller and softly lit in the background. A faint reflection in the spacecraft window is also visible, subtly overlaying the scene. Though their phases differ, both are shaped by the same sunlight, revealing the geometry of the Sun–Earth–Moon system from deep space. Credit: NASA

NASA’s Orion spacecraft — with crew — will dock with Mark 2 in lunar orbit. Then, two astronauts transfer to the lander and descend to the Moon’s South Pole.

After surface operations, Mark 2 returns to Orion, where the crew transfers for their journey back to Earth.

Ultimately, based on lander readiness, NASA will determine which company will be first selected to safely deliver astronauts to the Moon’s surface and back to lunar orbit in 2028. A second crewed landing opportunity will follow.

Artemis III will be one of the most complex test missions in NASA history.

Launching in 2027, Artemis III astronauts will practice rendezvous and docking with two commercial lunar landers designed to carry crew from the Orion spacecraft to the lunar surface.

Details below ⬇️
The Moon is seen shining over the Space Launch System rocket and Orion spacecraft atop the mobile launcher on January 28, 2026. The sky is a dark blue gradient in the background. The core stage of the rocket is a burnt orange color. It is topped with the white Orion spacecraft and sandwiched between two white solid rocket boosters. The mobile launcher is a trussed structure that stands behind the rocket. The perspective of the image if from below the rocket looking upward. Credit: NASA/Brandon Hancock

When ready, the Orion spacecraft and its crew will reenter Earth’s atmosphere and splash down in the Pacific Ocean, off the coast of California.

Every activity performed during Artemis III supports a larger goal: reducing risk before astronauts return to the lunar surface.

Artemis III is about learning.

The lessons learned throughout the mission will help refine future exploration plans, strengthen partnerships with industry, and ensure astronauts are prepared for humanity's next giant leap to the lunar surface in 2028. go.nasa.gov/4zpVyzj

Happy 65th birthday, NASA’s Stennis Space Center! 🎉

On Oct 25, 1961, NASA announced plans to build a rocket test site in south Mississippi to support the Apollo Program. In the decades since, work at the site has helped power every major chapter of America’s space program.
A Saturn V stage is lifted onto the A-2 Test Stand at NASA Stennis (1965).

“It’s crazy to look up and see the Moon far away again. I got used to seeing it bigger.”

Feel the Power of an RS‑25 Hot Fire Test! 🔥

We successfully tested RS-25 engine No. 10001 on Oct. 21 on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.

The main objectives of the test were to acceptance test RS-25 flight components for sions and validate the new thermal protection system, which protects the RS-25 engine nozzle from the thermal environment surrounding NASA’s SLS (Space Launch System) rocket during launch.

While this developmental engine will not be used in flight, the hot fire test provides NASA and NASA's prime engine contractor @L3HarrisTech with the capability to capture critical data to improve engine performance and reliability.

Two scientists. One unforgettable view of our planet.

What's it like to see the Artemis II Earthrise image through the eyes of a lunar scientist? How about an oceanographer? Jacob Richardson & Ivona Cetinic are here to tell us.
