Full Moon over Artemis II

A full moon is seen shining over NASA’s SLS (Space Launch System) and Orion spacecraft, atop the mobile launcher at Launch Pad 39B at NASA’s Kennedy Space Center in Florida in the early hours of February 1, 2026.

The agency concluded a wet dress rehearsal for the agency’s Artemis II test flight early Tuesday morning, successfully loading cryogenic propellant into the SLS (Space Launch System) tanks, sending a team out to the launch pad to closeout Orion, and safely draining the rocket. The wet dress rehearsal was a prelaunch test to fuel the rocket, designed to identify any issues and resolve them before attempting a launch. To allow teams to review data and conduct a second wet dress rehearsal, NASA now will target March as the earliest possible launch opportunity for the flight test.

NASA Space to Soil Challenge

Rapid advances in commercial space, artificial intelligence, and edge computing are transforming what is possible for Earth observation. By pushing more intelligence onboard, missions can move from passively collecting data to actively interpreting and responding to changing surface conditions in near-real time, enabling more targeted observations and dramatically improving the value of data returned to the ground. Within this context, land-focused applications such as regenerative agriculture, sustainable forestry, and broader land resilience efforts stand to benefit enormously from satellites that can adapt what, when, and how they sense based on dynamic environmental signals and algorithmic insight rather than fixed schedules or static acquisition plans.

NASA Earth Science Technology Office (ESTO) invites participants to design small satellite (SmallSat) mission concepts that leverage adaptive sensing and onboard processing to enhance regenerative agriculture, forestry, or a similar land resilience objective.​ Participants must work within onboard power, compute, and bandwidth constraints characteristic of SmallSat missions, focusing on how to orchestrate existing land observation algorithms into an efficient, responsive onboard intelligence layer.​ Both hardware-oriented and software-oriented solutions—or combinations of the two—are encouraged.

NASA’s primary objective for this challenge is to advance computational and systems approaches for adaptive sensing or onboard processing on SmallSat missions. The goal is not to develop new agricultural or forestry science but rather to improve how SmallSats sense, process, and deliver information to enable these applications.

Award: $400,000 in total prizes

Challenge Open Date: January 30, 2026

Submission Close Date: May 4, 2026

NASA Astronaut to Answer Questions from Students in Pennsylvania

NASA astronaut Chris Williams will connect with students in Pennsylvania to answer prerecorded science, technology, engineering, and mathematics (STEM) questions while aboard the International Space Station.

The Earth-to-space call will begin at 12:20 p.m. EST Thursday, Feb. 5, and will stream live on the agency’s Learn With NASA YouTube channel.

Media interested in covering the event must RSVP by 5 p.m., Wednesday, Feb. 4, to Tamara Krizek at: 917-692-5038 or tamara.krizek@davincisciencecenter.org.

The Da Vinci Science Center will host this event in Allentown, Pennsylvania, for students in kindergarten through grade 12, and members of the community. This unique opportunity aims to deepen understanding of space exploration and inspire young people to pursue a future career in STEM.

For more than 25 years, astronauts have continuously lived and worked aboard the space station, testing technologies, performing science, and developing skills needed to explore farther from Earth. Astronauts communicate with NASA’s Mission Control Center in Houston 24 hours a day through SCaN’s (Space Communications and Navigation) Near Space Network.

Research and technology investigations taking place aboard the space station benefit people on Earth and lay the groundwork for other agency deep space missions. As part of NASA’s Artemis campaign, the agency will send astronauts to the Moon to prepare for future human exploration of Mars, inspiring the world through discovery in a new Golden Age of innovation and exploration.

NASA’s Orion Spacecraft at Launch Pad

NASA’s Orion spacecraft, which will carry the Artemis II crew around the Moon, sits at the launch pad on Jan. 17, 2026, after rollout. It rests atop the SLS (Space Launch System) rocket. Orion can provide living space on missions for four astronauts for up to 21 days without docking to another spacecraft. Advances in technology for deep space travel such as life support, avionics, power systems, and state-of-the-art thermal protection will support the crew during launch, landing, and recovery.

NASA to Discuss Early Results of Artemis II Wet Dress Rehearsal

Following a fueling test of NASA’s SLS (Space Launch System) rocket at the launch pad for the Artemis II Moon mission, leaders will discuss initial results during a news conference at 12 p.m. EST on Tuesday, Feb. 3.

The agency’s SLS rocket and Orion spacecraft arrived at Launch Pad 39B at NASA’s Kennedy Space Center in Florida on Jan. 17. Since then, engineers have been conducting a variety of tests prior to launch. Underway now is a wet dress rehearsal, which requires filling the rocket with the 700,000 gallons of propellant. Call to stations began Jan. 31, and teams are counting down to a simulated launch window opening at 9 p.m. Monday. If more work is needed, NASA may rollback SLS and Orion into the Vehicle Assembly Building after the wet dress rehearsal.

The agency will stream the news conference live on its YouTube channel. A 24/7 live stream of the rocket remains online, as well as a separate feed for coverage of the wet dress rehearsal. Look for individual streams for these events to watch on YouTube. Learn how to stream NASA content through a variety of online platforms, including social media.

Participants in the news conference include:

• NASA Associate Administrator Amit Kshatriya
• Lori Glaze, acting associate administrator for the Exploration Systems Development Mission Directorate
• John Honeycutt, chair, Artemis II Mission Management Team
• Representative, Exploration Ground Systems Program

Following a successful wet dress rehearsal, NASA leaders will make a final call to send the Artemis II astronauts to Kennedy. The four crew members have been in quarantine in Houston since Jan. 21. If teams need more time to work on Artemis II hardware, crew can remain in Houston or exit quarantine.

If the crew members are sent to Kennedy, they are expected to fly NASA’s T-38s to Florida, arriving on the center about 3 p.m. on Feb. 3. They will participate in a media gaggle immediately following landing. Their gaggle also will stream live on NASA’s YouTube channel.

Participants include all four Artemis II crew members:

• Reid Wiseman, commander, NASA astronaut
• Victor Glover, pilot, NASA astronaut
• Christina Koch, mission specialist, NASA astronaut  
• Jeremy Hansen, mission specialist, CSA (Canadian Space Agency) astronaut

Media previously credentialed for launch may join these events in person. To participate in the news conference virtually, media must RSVP no later than two hours prior to the start of the call to Lauren Low in the Office of Communications at: lauren.e.low@nasa.gov. NASA’s media credentialing policy is online.

As part of a Golden Age of innovation and exploration, Artemis will pave the way for new U.S. crewed missions on the lunar surface in preparation to send the first astronauts to Mars.
