Artemis II begins historic lunar journey
NASA's Orion spacecraft successfully executed a critical engine maneuver Tuesday, propelling four astronauts out of Earth's orbit and toward the Moon for the first time in over five decades.
Translunar injection marks mission milestone
The five-minute, 55-second burn-known as translunar injection (TLI)-concluded without incident, NASA planetary science director Dr. Lori Glaze confirmed. The maneuver accelerated Orion to speeds needed to escape Earth's gravitational pull.
From inside the capsule, Canadian astronaut Jeremy Hansen radioed mission control: "We're feeling pretty good up here on our way to the Moon." Hansen, the first non-American to join a lunar mission, added that the crew "firmly felt the power" of global collaboration behind the effort.
"Humanity has once again shown what we are capable of. It's your hopes for the future that carry us now on this journey around the Moon."

Orion sets course for record-breaking distance
Following a day-long systems check in high Earth orbit, Orion's service module ignited its main engine, adding thousands of kilometers per hour to its velocity. The TLI burn placed the spacecraft on a trajectory that will carry the crew approximately 7,600 km beyond the Moon-potentially surpassing Apollo 13's 1970 record for the farthest humans have traveled from Earth.
NASA officials emphasized that the crew remains in reach of an emergency return. Orion program manager Howard Hu explained that a "handbrake turn" maneuver could bring the astronauts home within 36 hours of TLI if needed. After that window, continuing around the Moon would be the safer option.
Cosmic sights await as mission progresses
As Orion ventures deeper into space, the crew will witness Earth shrink to a distant blue marble while the Moon grows from a bright disc to a cratered landscape filling their viewports. On day six, they are expected to observe a total solar eclipse, with the Moon completely obscuring the Sun to reveal its shimmering corona.
Next steps in lunar exploration
The Artemis II mission serves as a precursor to NASA's planned lunar landings, testing Orion's systems ahead of future crewed surface missions. If successful, it will pave the way for the first human Moon landing since 1972.
"What a great couple of days!" Hu told reporters after the TLI burn, underscoring the team's confidence in the spacecraft's performance.
