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!

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 ⬇️

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. More:

While Orion is docked with Starship, Starship will perform a trans-lunar injection burn to bring the connected spacecraft to lunar orbit. Starship will bring two astronauts to the lunar surface for several days before delivering them back to Orion for the ride back to Earth.

Blue Origin’s Blue Moon Mark 2 lander will operate differently. Blue Origin will use three transfer stages that operate like a multistage rocket to launch into low Earth orbit, and then enter lunar orbit. Each transfer stage separates as its propellant runs out.

SpaceX’s Starship HLS will rendezvous and dock with the Orion spacecraft and its crew in low Earth orbit. Similar to a gas station on Earth, a series of propellant “tanker” Starships will transfer propellant to the waiting “depot” Starship.

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 ⬇️

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.

SpaceX will launch a Starship Version 3 test article to rendezvous and dock with Orion in a test expected to last up to two hours. While the astronauts will not enter Starship during this test, the team will evaluate how Orion and Starship interact as a docked system in space.

Even after docking activities are complete, Artemis III will continue generating data that supports future missions. NASA will evaluate the performance of Orion Crew Survival System suits, measure acoustics inside of Orion, and perform science and technology demonstrations.

NASA’s Artemis III mission will last about two weeks. The mission begins when Blue Origin launches a test version of its Blue Moon Mark 2 lander into orbit. Days after, four astronauts will launch aboard the Orion spacecraft on top of the Space Launch System rocket.

Following a checkout of Orion’s systems, the mission’s first major objective begins: rendezvous and docking with the Blue Moon test vehicle. The astronauts will open the hatch and enter the spacecraft. After their assessment, they return to Orion. Then, Orion undocks.

The Artemis III crew and @USNavy teams recently practiced hoist operations in San Diego as part of recovery training. Training during the day and at night helps the crew become familiar with the wind, noise, and sea spray they will experience during splashdown and recovery.

We've got your nose(cones)! NASA’s twin SLS boosters for Artemis III are now fully stacked, with nose cones integrated inside the Vehicle Assembly Building at @NASAKennedy.

There’s a full Moon rising. The Harvest Moon is the full Moon that occurs closest to the fall equinox. This year, it's on Saturday, Sept. 26. As the Harvest Moon rises in the east shortly after sunset, Saturn will appear nearby. Take a moment to look up and enjoy the view.

Piece by piece! The left forward segment is the latest piece to be stacked for the Artemis III boosters, leaving just one more to go before all 10 are together. The twin SLS solid rocket boosters provide more than 75% of the thrust at liftoff—talk about a powerful pair! 💥

What a Moon. 🌓 On August 27-28, a lunar eclipse was seen across much of North and South America, as well as parts of Europe and Africa. If you're hungry for more lunar observations, International Observe the Moon Night is coming up on Saturday, Sept. 19! Join from anywher... 🔗 go.nasa.gov/3T15WgR

Cementing their names in history. The Artemis III crew is leaving their mark — literally. The astronauts recently signed their names on the hardware that will be inside their Orion spacecraft during their low Earth orbit mission, launching in 2027.

The boosters for the Artemis III mission are getting stacked! Technicians are stacking the twin solid rocket boosters for the Space Launch System rocket at @NASAKennedy. The boosters will provide more than 75% of the rocket’s total thrust at launch — scheduled for 2027.

While NASA’s Artemis III mission moves forward, work on Artemis IV and V is already underway! 🚀 At NASA's Michoud Assembly Facility in New Orleans, Louisiana, teams are making steady progress on the core stages for the SLS rockets. Here’s a look at some recent moves and tests:

Core Stage IV: 🚀Hydrostatic proof testing of the liquid oxygen tank is complete. 🚀Hydrostatic proof testing of the liquid hydrogen tank is complete. 🚀The boat tail is on its way to @NASAKennedy Space Center (pictured above.)

@NASAKennedy Core Stage V: 🚀The barrel of the engine section was loaded into the Vertical Assembly Center and team members installed a ring that will serve as the attachment point for the liquid hydrogen tank later in the production process.

In early April 2026, the Artemis II crew became the first to travel beyond the Moon in more than 50 years and traveled farther in space than humans have ever before. For their achievements, each was awarded with the Congressional Space Medal of Honor today. Congratulations!

Look up tonight. The Moon will pass through Earth's shadow during a deep partial lunar eclipse visible from much of North and South America and parts of Europe and Africa. As the eclipse deepens, the Moon will appear tinged with shades of red and copper.

Making a mess... to benefit humanity! To help NASA and commercial partners better understand the science of lunar landings, @NASALangley has started a series of complex plume-surface interaction tests inside a massive 60-foot spherical vacuum chamber. t.co/eihfwO7GIx

POV: Your office has the best view. NASA's Artemis missions are taking humanity farther than ever before. NASA's photographers work hard to take you all along for the ride. Happy #WorldPhotographyDay!

Two more booster segments for the Artemis III rocket have been stacked at @NASAKennedy. Four out of 10 motor segments are now stacked! The Artemis III mission will launch in 2027 to test rendezvous and docking capabilities between Orion and commercial lunar landers.

Wrenches down. Engineers have completed hardware development on NASA’s Lunar Environment Monitoring Station, which will monitor moonquakes and meteorite impacts to prepare astronauts for hazards when they are living and working on the surface of the Moon.
