NASA Johnson’s 2025 Milestones
NASA Johnson’s 2025 Milestones: A Year of Breakthroughs in Space Exploration
As the year 2025 comes to a close, NASA's Johnson Space Center in Houston has achieved significant milestones in human spaceflight, research, and exploration. From the Artemis II mission preparations to the success of the OSIRIS-REx asteroid sample return, teams at Johnson have made tremendous progress in advancing the next era of space exploration.
Orion Stacked for Artemis II, Orion Mission Evaluation Room Unveiled
In October 2025, NASA completed stacking of the Orion spacecraft and launch abort system atop the agency's SLS (Space Launch System) rocket inside the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. This critical step marked a major milestone in the Artemis II mission, which will carry NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen on a 10-day journey around the Moon and back in early 2026.
The new Orion Mission Evaluation Room inside the Mission Control Center at NASA's Johnson Space Center in Houston was also unveiled, allowing engineers to monitor Orion spacecraft systems in real-time and assess vehicle performance throughout the mission. This facility will play a crucial role in the success of the Artemis II mission and will strengthen flight operations beyond low Earth orbit.
Gateway Lunar Space Station
The Gateway Program continued progress toward building humanity's first lunar space station, with the powerhouse reaching a major milestone this fall with its successful initial power on. The Gateway will serve as a vital stepping stone for future missions to the Moon and will provide a sustainable presence in lunar orbit.
A Space Station Anniversary
On November 2, 2025, NASA marked 25 years of continuous human presence aboard the space station. What began as a framework of modules has evolved into a springboard for international cooperation, advanced scientific research, and technology demonstrations. The space station has been visited by more than 290 people from 26 countries and a variety of international and commercial spacecraft.
Record-Breaking Spacewalks
NASA astronauts Nick Hague, Suni Williams, and Butch Wilmore began 2025 with two successful spacewalks, completing key maintenance and research tasks. Their work included removing an antenna assembly and collecting surface material samples for analysis at Johnson's Astromaterials Research and Exploration Services, or ARES, division. With her latest spacewalks, Williams now holds the record for the most cumulative spacewalking time by a woman – 62 hours and 6 minutes – placing her fourth among the most experienced spacewalkers.
Two Expeditions Take Flight
NASA's SpaceX Crew-10 arrived at the International Space Station on March 15 and returned to Earth on August 9. Crew-10 included NASA astronauts Anne McClain and Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov – all of whom are trained pilots. Crew-9 also splashed down off Florida's coast on March 18.
A Year of Lunar Firsts
Firefly Aerospace's Blue Ghost Mission 1 launched on March 2, delivering 10 NASA science and technology instruments to the Moon as part of the Commercial Lunar Payload Services (CLPS) initiative and Artemis campaign. The lander touched down near Mons Latreille in Mare Crisium, a basin on the near side of the Moon. Just days later on March 6, Intuitive Machines' IM-2 mission landed closer to the lunar South Pole than any previous lander.
First Asteroid-Detecting Space Telescope Completes Testing
NASA's Near-Earth Object (NEO) Surveyor – its first space-based telescope designed specifically for planetary defense – has successfully completed thermal vacuum testing in Johnson's Space Environment Simulation Laboratory in Chamber A. Set to launch no earlier than late 2027, NEO Surveyor will seek out, measure, and characterize hard-to-detect asteroids and comets that could pose a hazard to Earth.
First Houston AutoBoative Show
For the first time, NASA rolled out its Artemis exhibit at the Houston AutoBoative Show at NRG Center from January 29 to February 2. Johnson employees introduced vehicle enthusiasts to the technologies NASA and its commercial partners will use to explore more of the lunar surface than ever before.
First Dual NBL Run for NASA's Artemis III Lunar Spacesuit
NASA and Axiom Space teams held the first dual spacesuit run at NASA's Neutral Buoyancy Laboratory with NASA astronauts Stan Love and Loral O'Hara. Both crewmembers wore Axiom Space's lunar spacesuit, called the Axiom Extravehicular Mobility Unit (AxEMU), while performing simulated lunar surface operations underwater to test the spacesuit's functionality and mobility.
OSIRIS-REx Team Honored for Asteroid Sample Return
NASA's OSIRIS-REx curation team earned an Agency Group Achievement Award for their dedication to acquiring, preserving, and distributing asteroid samples from Bennu – the agency's first asteroid sample return mission. The team overcame unforeseen technical challenges to recover and preserve more than 120 grams of asteroid material – now accessible to scientists worldwide for research into the origins of our solar system.
Axiom Mission 4 Marks International Firsts in Space Station Mission
The Axiom Mission 4 crew successfully returned to Earth after an 18-day mission aboard the space station, conducting more than 60 experiments and educational outreach activities. Launched aboard a SpaceX Dragon spacecraft on June 25, the crew docked with the orbiting laboratory the following day to begin a packed schedule of science and outreach.
Johnson-Built Mars Hardware on Display at the Smithsonian
A piece of NASA Johnson Space Center's Mars legacy has landed at the Smithsonian National Air and Space Museum in Washington, D.C. The Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals (SHERLOC) calibration target – built by Johnson's ARES Division with partners at NASA's Jet Propulsion Laboratory and Amentum – now has a permanent place in the museum's Futures in Space gallery.
As the year 2025 comes to a close, NASA's Johnson Space Center has achieved significant milestones in human spaceflight, research, and exploration. From the Artemis II mission preparations to the success of the OSIRIS-REx asteroid sample return, teams at Johnson have made tremendous progress in advancing the next era of space exploration. As we look to the future, we can expect even more breakthroughs and innovations from NASA's Johnson Space Center.
