CAPE CANAVERAL, Fla. (FNN) — For the first time in more than 50 years, astronauts on a NASA mission are headed around the Moon after successfully completing a critical burn of the Orion spacecraft’s main engine.

The approximately six-minute firing of Orion’s service module engine Thursday — known as the translunar injection burn — accelerated the spacecraft and its crew beyond Earth’s orbit, placing them on a trajectory toward the Moon.

Aboard the spacecraft are NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, along with Canadian Space Agency astronaut Jeremy Hansen.

“Today, for the first time since Apollo 17 in 1972, humans have departed Earth orbit,” said Dr. Lori Glaze, acting associate administrator for NASA’s Exploration Systems Development Mission Directorate. “Reid, Victor, Christina and Jeremy now are on a precise trajectory toward the Moon. Orion is operating with crew for the first time in space, and we are gathering critical data and learning from each step.”

NASA’s Space Launch System rocket and Orion spacecraft lifted off from Launch Pad 39B at Kennedy Space Center at 6:35 p.m. EDT on April 1, beginning a planned 10-day test mission around the Moon and back.

Successful Launch and Spacecraft Activation

Shortly after reaching space, Orion deployed its four solar array wings, allowing the spacecraft to generate power from the Sun. The crew and mission controllers then began transitioning the spacecraft from launch to normal flight operations while checking critical onboard systems.

About 49 minutes into the flight, the rocket’s upper stage fired to place Orion into an elliptical orbit around Earth. A second burn propelled the spacecraft — named “Integrity” by the crew — into a high Earth orbit extending roughly 46,000 miles above the planet for nearly 24 hours of system testing.

Following the maneuver, Orion separated from the upper stage and began flying independently.

System Tests and Crew Operations in Space

During the early phase of the mission, the astronauts conducted a manual piloting demonstration to evaluate Orion’s handling capabilities using the Interim Cryogenic Propulsion Stage as a docking target.

After the test, Orion executed an automated departure burn to safely move away from the stage. The propulsion stage later performed a disposal burn before re-entering Earth’s atmosphere over a remote area of the Pacific Ocean.

Before its re-entry, four small CubeSats were deployed from the rocket’s Orion stage adapter to conduct separate scientific missions.

Mission teams also transitioned communications to NASA’s Deep Space Network while the crew adjusted to the space environment. Astronauts completed their first rest periods, performed onboard exercise routines, restored the spacecraft’s toilet to normal operations and prepared the spacecraft for the translunar injection burn.

Lunar Flyby and Artemis Program Goals

The crew is scheduled to conduct a lunar flyby Monday, April 6, when astronauts will capture high-resolution images and make observations of the Moon’s surface — including portions of the lunar far side rarely seen directly by humans.

Although the far side will only be partially illuminated during the flyby, the lighting conditions are expected to cast long shadows across the terrain, highlighting ridges, slopes and crater rims that are difficult to observe under full sunlight.

After completing the flyby, the astronauts will return to Earth and splash down in the Pacific Ocean off the coast of San Diego.

The mission marks a major milestone for NASA’s Artemis program, which aims to send astronauts on increasingly ambitious missions to explore the Moon, advance scientific discovery, stimulate economic growth and prepare for the first crewed missions to Mars.

WASHINGTON, D.C. (FNN) — NASA astronaut Jonny Kim returned to Earth early Tuesday alongside Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky, concluding an eight-month science mission aboard the International Space Station focused on advancing life on Earth and preparing for future deep space exploration.

The trio landed safely under parachute at 12:03 a.m. EST (10:03 a.m. local time) southeast of Dzhezkazgan, Kazakhstan, aboard the Soyuz MS-27 spacecraft. Their departure from the station occurred at 8:41 p.m. EST on Dec. 8.

Record-Breaking Mission and First-Time Flyers

Across 245 days in orbit, the crew circled Earth 3,920 times and traveled nearly 104 million miles. Kim and Zubritsky completed their first spaceflights, while Ryzhikov—on his third mission—now holds 603 cumulative days in space.

The crew launched to the ISS on April 8 as part of a mission that contributed to NASA’s long-running efforts to advance scientific discovery and human spaceflight capabilities.

Scientific Research to Benefit Earth and Future Missions

While aboard the ISS, Kim supported numerous experiments and technology demonstrations. His work included studying the behavior of bioprinted tissues with blood vessels in microgravity—research that could accelerate space-based tissue production and improve medical treatments on Earth.

Kim also tested multi-robot remote command capabilities for the Surface Avatar investigation, a study that could inform the development of robotic assistants for future lunar and Martian missions. In addition, he contributed to research on in-space manufacturing of DNA-mimicking nanomaterials, which may enhance drug delivery systems and support emerging fields in regenerative medicine.

Return to Houston and the Future of Exploration

After routine medical checks in Kazakhstan, the crew will travel to the recovery staging area in Karaganda. Kim will then return to NASA’s Johnson Space Center in Houston.

For more than 25 years, astronauts have lived and worked continuously aboard the International Space Station, enabling scientific breakthroughs not achievable on Earth. As commercial partners expand human spaceflight services and develop new low Earth orbit destinations, NASA is directing its focus toward deep space exploration through the Artemis program and preparing for eventual human missions to Mars.
