Preparing for Artemis II: Training for a Mission Around the Moon
Four astronauts will soon travel beyond low Earth orbit and fly around the Moon on Artemis II, a mission that will test NASA’s systems and hardware for human exploration of deep space.
Since June 2023, NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen have been preparing for their lunar journey. The approximately 10-day mission will test the SLS (Space Launch System) rocket and Orion spacecraft, named Integrity by the crew, while requiring the quartet to operate with greater autonomy and make critical decisions far from Earth.

Unlike missions to the International Space Station, Artemis II offers no nearby safe harbor and no option to be back on Earth within hours of a problem. Training reflects that reality. Crews are prepared not just to follow procedures, but to understand spacecraft systems well enough to adapt when conditions change.
Training began with mission fundamentals, including how Orion and SLS systems function individually and together. From there, the crew progressed through phases of training that moved from routine on-orbit operations to more complex mission segments such as ascent, entry, and landing. Each phase builds on the last as the crew moves closer to flight.
In parallel, astronauts trained in medical operations, exercise systems, spacesuits, and daily life aboard Orion. Together, these elements form a single, integrated mission timeline.

A key part of Artemis II training includes lunar observation and photography. At NASA’s Johnson Space Center in Houston, astronauts studied the Moon’s far side, learning to identify crater shapes, surface textures, color variations, and reflectivity.
Although Artemis II will not land on the Moon, the crew will conduct detailed observations from lunar orbit to prepare for future Artemis missions.
Flight Training at Ellington Field Artemis II crew members Reid Wiseman and Christina Koch during T-38F flight training at Ellington Field.NASA/Josh Valcarcel
In addition to classroom instruction and simulations, the Artemis II crew trains in T-38 jet aircraft at Johnson’s Ellington Field. The T-38 exposes astronauts to high-workload, dynamic flight conditions that build spatial awareness and adaptability, skills that translate directly to decision-making under pressure in spaceflight.
Protecting Crew Health in Deep Space The Artemis II crew don their Orion Crew Survival System spacesuits for post landing emergency egress inside the Orion Mockup at Johnson’s Space Vehicle Mockup Facility.NASA/James Blair
The crew donned their Orion Crew Survival System spacesuits during training to support testing of Orion’s environmental control and life support systems. The suit provides pressure, oxygen, and thermal protection during launch, entry, and contingency scenarios while Orion’s life support systems manage cabin oxygen, water, temperature, and overall crew health throughout the mission.
Mastering Orion Systems and Simulations Artemis II Commander Reid Wiseman (front) and Pilot Victor Glover participate in an Artemis II entry simulation at Johnson Space Center.NASA/Bill Stafford
Inside the Orion Mission Simulator at Johnson, the crew rehearsed every phase of the mission, from routine operations to emergency response. Simulations are designed to teach astronauts how to diagnose failures, manage competing priorities, and make decisions with delayed communication from Earth.
Through this process, the quartet learned every aspect of the Orion crew module’s interior, including how to navigate onboard displays and execute the procedures used to fly and monitor the spacecraft.

While Artemis II astronauts will not land on the Moon, the geology fundamentals they develop during field training in remote environments are critical to meeting the mission’s science objectives.
During the mission, the crew will examine a targeted set of surface features, including craters and regolith, from orbit. Astronauts will document variations in color, reflectivity, and texture to help scientists interpret geologic history.
Preparing for Splashdown and Recovery The Artemis II astronauts during water survival recovery training at NASA’s Neutral Buoyancy Laboratory. NASA/Josh Valcarcel
The mission will conclude when the Artemis II mission splashes down.
The crew worked through splashdown and recovery operations at the agency’s Neutral Buoyancy Laboratory. They rehearsed how to exit the Orion spacecraft safely in different scenarios, stabilize the spacecraft, and board a raft – skills they will rely on after returning from their mission around the Moon.

The Artemis II crew also completed integrated ground systems tests at NASA’s Kennedy Space Center in Florida. These included suited tests, full mission rehearsals, and launch-day dry runs that walked astronauts through every step, from traveling to the launch pad to entering Orion at Launch Pad 39B.
As Artemis II moves closer to launch, the focus shifts from preparation to readiness as the crew enters the next era of exploration beyond low Earth orbit.

Goldstone’s DSS-15 Antenna and the Milky Way
Deep Space Station 15, one of the 112-foot antennas at the Goldstone Deep Space Communications Complex near Barstow, California, looks skyward, with the stars of the Milky Way overhead, in September 2025. Goldstone is part of NASA’s Deep Space Network (DSN), which operates three complexes around the globe that support communications with dozens of deep space missions.
The DSN is NASA’s international array of giant radio antennas that supports interplanetary spacecraft missions, plus a few that orbit Earth. The DSN also provides radar and radio astronomy observations that improve our understanding of the solar system and the larger universe.
Through Artemis, NASA is establishing an enduring presence in space and exploring more of the Moon than ever before. To achieve this, Artemis missions rely on both the Deep Space Network and the Near Space Network. These networks, with oversight by NASA’s SCaN (Space Communications and Navigation) Program office, use global infrastructure and relay satellites to ensure seamless communications and tracking as Orion launches, orbits Earth, travels to the Moon, and returns home.

Artemis II Recovery Training
Off the coast of California, NASA’s Artemis Landing and Recovery team and the Department of War that will work together to retrieve the Artemis II crew and Orion spacecraft following their return to Earth and splashdown in the Pacific Ocean are performing a final simulation of their activities, called a just-in-time training, at sea on Tuesday, Jan. 27, 2026. During the training, teams use the Crew Module Test Article, a full-scale mockup of the Orion spacecraft, to simulate as close as possible the conditions they can expect to encounter during splashdown of the Artemis II mission. NASA’s first crewed test flight in the Artemis campaign, the approximately 10-day Artemis II mission will send NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen around the Moon and farther than any humans have ever been from Earth.

New Measurements of Europa's Ice Shell Taint the Icy Moon's Potential Habitability
Jupiter's icy moon Europa is a tantalizing target in the search for habitability in our Solar System. Its thick, global ice sheet overlies a warm, salty, chemically-rich ocean. But for life to exist in that ocean, nutrients need to find their way from the surface to the ocean. New research says that may be very difficult.
Another Earth or a blip in the data? We may never find out
An exoplanet called HD 137010 b might be the closest thing astronomers have ever seen to “Earth 2.0.” The trouble is that it’s only been seen once—and may never be glimpsed again

Description
The NISAR (NASA-ISRO Synthetic Aperture Radar) Earth-observing satellite’s L-band synthetic aperture radar (SAR) instrument captured this image of the Mississippi River Delta region in southeastern Louisiana on Nov. 29, 2025.
The colors in the image represent varying types of cover, which tend to reflect microwaves from the radar differently. Portions of New Orleans appear green, a sign that the radar’s signals may be scattering from buildings that are oriented at different angles relative to the satellite’s orbit. Parts of the city appear magenta where streets that run parallel to the satellite’s flight track cause the signals to bounce strongly and brightly off buildings and back to the instrument.
The resolution of the image is fine enough to make clear, right of center, the Lake Pontchartrain Causeway — twin bridges that, at nearly 24 miles (39 kilometers) in length, make up the world’s longest continuous bridge over water.
The bright green areas to the west of the Mississippi River, which snakes from Baton Rouge in the upper left to New Orleans in the lower right, are healthy forests. There, tree canopies and other vegetation are causing NISAR’s microwaves to bounce in numerous directions before returning to the satellite. Meanwhile, the yellow-and-magenta-speckled hues of Maurepas Swamp, directly west of Lake Pontchartrain and the smaller Lake Maurepas, indicate that the tree populations in that wetland forest ecosystem have thinned.
On either bank of the Mississippi, the image shows parcels of varying shapes, sizes, and cover. Darker areas suggest fallow farm plots, while bright magenta indicates that tall plants, such as crops, may be present.
Figure A
Figure A is a version of the same image with labels, locator inset, scale, or compass.
The L-band system uses a 9-inch (24-centimeter) wavelength that enables its signal to penetrate forest canopies and measure soil moisture as well as motion of ice surfaces and land down to fractions of an inch — the latter information being key to understanding how the land surface moves before, during, and after earthquakes, volcanic eruptions, and landslides.
The S-band radar, provided by the Indian Space Research Organisation’s Space Applications Centre, uses a 4-inch (10-centimeter) microwave signal that’s more sensitive to small vegetation, which makes it effective at monitoring certain types of agriculture and grassland ecosystems.
Launched in July 2025, NISAR is collecting data that will benefit humanity by helping researchers around the world better understand changes in our planet’s surface, including its ice sheets, glaciers, and sea ice. It also will capture changes in forest and wetland ecosystems and track movement and deformation of our planet’s crust by phenomena such as earthquakes, landslides, and volcanic activity. The global and rapid coverage from NISAR will provide unprecedented support for disaster response, producing data to assist in mitigating and assessing damage, with observations before and after catastrophic events available in short time frames.

Boron Could Be Astrobiology’s Unsung Hero
The light, rare element boron, better known as the primary component of borax, a longtime household cleaner, was almost mined to exhaustion in parts of the old American West. But boron could arguably be an unsung hero in cosmic astrobiology, although it's still not listed as one of the key elements needed for the onset of life.

Perseverance Rover Discovers an Ancient Martian Beach, Complete with Waves
When the rover now named Perseverance landed in Jezero crater in early 2021, scientists already knew they had picked an interesting place to scope out. From space, they could see what looked like a bathtub ring around the crater, indicating there could once have been water there. But there was some debate about what exactly that meant, and it’s taken almost five years to settle it. A new paper from PhD student Alex Jones at Imperial College London and his co-authors has definitively settled the debate on the source of that feature - part of it was once a beach.
