At 1:20 p.m. EDT, NASA astronaut Chris Williams, with assistance from NASA astronaut Jack Hathaway, captured Northrop Grumman’s Cygnus XL spacecraft using the International Space Station’s Canadarm2 robotic arm.

NASA’s Mission Control Center at the agency’s Johnson Space Center in Houston will use Canadarm2 to position the spacecraft for installation, then guide Cygnus XL to the Unity module’s Earth-facing port. NASA will not provide live coverage of the spacecraft’s installation.

NASA’s Northrop Grumman Commercial Resupply Services 24 mission launched at 7:41 a.m. on April 11 on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida, carrying more than 11,000 pounds of scientific investigations and cargo to the orbiting laboratory.

Northrop Grumman named the spacecraft the S.S. Steven R. Nagel in honor of the former NASA astronaut who flew four space shuttle missions, logging more than 720 hours in space.

Cygnus XL Cargo Craft Approaching Station for Robotic Capture

Cygnus XL Cargo Craft Approaching Station for Robotic Capture

Northrop Grumman's Cygnus XL cargo craft, carrying over 11,000 pounds of new science and supplies for the Expedition 73 crew, is pictiured moments before its capture with the International Space Station's Canadarm2 robotic arm. Both spacecraft were orbiting 257 miles above Namibia. Cygnus XL is Northrop Grumman's expanded version of its previous Cygnus cargo craft increasing its payload capacity and pressurized cargo volume.

NASA will roll the largest section of the agency’s SLS (Space Launch System) rocket, which will launch the second crewed Artemis mission, out of the agency’s Michoud Assembly Facility in New Orleans on Monday, April 20. What’s called the top four-fifths of the SLS core stage – the section containing the liquid hydrogen tank, liquid oxygen tank, intertank, and forward skirt – will be loaded on the agency’s Pegasus barge for delivery to NASA’s Kennedy Space Center in Florida.

Media will have the opportunity to capture images and video, hear remarks from agency and industry leadership, and speak with NASA subject matter experts and Artemis industry partners as crews move the rocket stage to the Pegasus barge.

This event is open to U.S. media, who must apply by Wednesday, April 15. Interested media must contact Jonathan Deal at jonathan.e.deal@nasa.gov and Craig Betbeze at craig.c.betbeze@nasa.gov. Registered media will receive confirmation and additional information about the event by email. The agency’s media credentialing policy is available online.

Once at NASA Kennedy, teams will complete the stage outfitting and vertical integration before handing the hardware over to the agency’s Exploration Ground Systems Program that will handle stacking and launch preparations. The Artemis III SLS engine section and boat-tail, which protects the engines during launch, moved from the Space Systems Processing Facility at NASA Kennedy to the Vehicle Assembly Building in July 2025. The four core stage RS-25 engines are scheduled to ship from NASA’s Stennis Space Center in Bay St. Louis, Mississippi no later than July 2026 for integration into the engine section.

The rocket stage with its four RS-25 engines will provide more than 2 million pounds of thrust to send astronauts aboard the Orion spacecraft for the Artemis III mission. Artemis III currently is scheduled for launch in 2027, following the successful Artemis II test flight mission around the Moon that concluded April 10.

Building, assembling, and transporting the core stage is a collaborative process for NASA, Boeing, the core stage lead contractor, and lead RS-25 engines contractor L3Harris Technologies. The core stage is the backbone of the SLS rocket. All five major structures for the rocket stage are manufactured at NASA Michoud. By optimizing space at NASA Kennedy and NASA Michoud for production, integration, and outfitting, NASA and industry can streamline production for a standardized SLS configuration for NASA’s Artemis program.

The Artemis III mission will launch to Earth’s orbit American astronauts in the Orion spacecraft on top of the SLS rocket to test rendezvous and docking capabilities between Orion and commercial spacecraft needed to land astronauts on the Moon in 2028. The SLS rocket is the only rocket capable of sending Orion, astronauts, and supplies to the Moon in a single launch.

Artemis III is the second crewed mission under the agency’s Artemis program, where NASA is sending astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, establish an enduring human presence on the lunar surface, and build on our foundation for the first crewed missions to Mars.

NASA Announces 32nd Annual Human Exploration Rover Challenge Winners

NASA Announces 32nd Annual Human Exploration Rover Challenge Winners

NASA’s 32nd annual Human Exploration Rover Challenge, one of the agency’s longest-standing student challenges, culminated April 10-11 with its final excursion event at the U.S. Space & Rocket Center near NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Spanning nine months, the challenge tasks student teams from around the world to design, build, and test a lunar rover powered by either human pilots or remote control. The annual competition concluded with an awards ceremony recognizing the top-performing teams.

This video highlights student teams from around the world that competed in NASA’s 2026 Human Exploration Rover Challenge, held April 10–11 at the U.S. Space & Rocket Center near the agency’s Marshall Space Flight Center in Huntsville, Alabama. Teams navigated a challenging obstacle course and completed complex mission tasks using human-powered and remote-controlled rovers.

In the human-powered division, Parish Episcopal School in Dallas, Texas earned first place in the high school division, while the University of Central Missouri in Warrensburg, Missouri, won the college and university title. In the remote-control division, Gould Academy in Bethel, Maine, earned the top award in the middle and high school division, and The University of Alabama in Huntsville in Huntsville, Alabama, secured the college and university title.

More than 500 students representing 42 teams from around the world participated in the 32nd annual competition. Teams included students from 28 colleges and universities, 13 high schools, and one middle school across 18 U.S. states, Puerto Rico,

Teams were scored on their ability to navigate a half-mile obstacle course, complete mission-specific task challenges, and pass multiple safety and design reviews conducted by NASA engineers, with awards presented across human-powered and remote-control divisions.

“This challenge gives students a hands-on opportunity to think like engineers and problem-solvers, applying real-world design principles to complex exploration scenarios,” said Vemitra Alexander, who leads the Human Exploration Rover Challenge for NASA’s Office of STEM Engagement at Marshall. “By encouraging innovation and teamwork, we’re helping prepare the next generation to contribute to missions that will take us farther into space.”
