Six days after liftoff from Kennedy Space Center, four astronauts on NASA’s Artemis II mission reached a milestone in human exploration when, at 12:56 p.m. CDT on Monday, they were 248,655 miles from Earth, surpassing the 1970 Apollo 13 distance record; mission planners say Orion will reach a peak distance of about 252,756 miles before beginning its return. The crew — NASA astronauts Reid Wiseman, Victor Glover, Christina Koch and CSA astronaut Jeremy Hansen — are conducting photographic and observational work during the outbound leg of a multi-orbit, crewed lunar test flight. NASA updated its release at 7:28 p.m. EDT on April 6, 2026 to adjust Orion’s closest approach (now about 4,067 miles) and the mission’s farthest-distance figures and to refine wording about crew achievements. The test flight remains on track for a planned splashdown off San Diego about 8:07 p.m. EDT on Friday, April 10, with recovery operations staged from USS John P. Murtha.
Key takeaways
- At 12:56 p.m. CDT on Monday, Artemis II reached 248,655 miles from Earth, exceeding the Apollo 13 record set in 1970.
- Mission updates list Orion’s maximum outbound distance at roughly 252,756 miles and a closest lunar approach near 4,067 miles (updated April 6, 2026, 7:28 p.m. EDT).
- The four-person crew — Wiseman, Glover, Koch and Hansen — continue systematic lunar photography and telemetry collection for Artemis program validation.
- A planned approximately 40-minute communications blackout will occur when Orion transits behind the Moon, with Deep Space Network handovers expected afterward.
- Crew proposed two informal crater names, Integrity (after the spacecraft) and Carroll (in honor of Wiseman’s late wife); formal naming requires International Astronomical Union approval.
- Splashdown and recovery are scheduled for about 8:07 p.m. EDT on April 10; post-flight medical checks will be conducted aboard USS John P. Murtha.
Background
The Artemis program is NASA’s long-term effort to return humans to lunar vicinity and eventually establish sustained presence on and around the Moon as preparation for crewed Mars missions. Artemis II is the program’s first crewed flight test and follows a series of uncrewed missions and hardware validations, including Orion spacecraft tests and Space Launch System (SLS) development. Historically, Apollo-era missions set distance and duration benchmarks for human space travel; Apollo 13’s outbound trajectory in April 1970 held the farthest-distance record for more than five decades until Artemis II’s outbound leg.
Artemis II launched April 1, 2026 on an SLS rocket from Kennedy Space Center and executed burns to depart Earth orbit the next day, establishing a trans-lunar trajectory. The flight is configured as a test campaign: crew operations, life-support performance, navigation, communications handoffs with Earth’s Deep Space Network, and crew photography are all evaluated to validate systems and procedures for subsequent, more ambitious Artemis missions. International partnership is integral: Canada’s inclusion of an astronaut and other international hardware and scientific collaboration reflect broader program goals.
Main event
On Monday at 12:56 p.m. CDT, telemetry showed the Orion crew was 248,655 miles from Earth, a distance mission control confirmed exceeded the Apollo 13 record. Flight controllers report that the spacecraft will continue to coast outward to a mission peak near 252,756 miles before beginning the return leg, a trajectory profile planned to stress Orion’s navigation and thermal performance. The April 6 update shifted the reported peri-lunar closest approach slightly to about 4,067 miles from the lunar surface.
During the outbound transit, crew members have been using handheld digital cameras and other imaging tools to photograph lunar terrain under varying lighting conditions; NASA emphasizes human visual observation as an important complement to automated sensors. The crew also conducted routine systems checks and exchanged short status reports with Mission Control. About 40 minutes of planned blackout is expected when Orion moves behind the Moon and line-of-sight communications to Earth are interrupted; full contact is expected to resume as Orion emerges and reestablishes a Deep Space Network link.
Onboard announcements and brief, emotional remarks followed the milestone. The crew also proposed informal names for two lunar depressions — one after their spacecraft, Integrity, and the other honoring astronaut Reid Wiseman’s late wife, Carroll — and NASA confirmed those proposals will be submitted to the International Astronomical Union for formal consideration after mission completion. Recovery teams are preparing for helicopter retrieval of the astronauts and transfer to USS John P. Murtha for post-flight medical evaluation before ground transport to Johnson Space Center.
Analysis & implications
The new farthest-human-distance mark underscores the Artemis program’s technical progress while remaining a test rather than an operational surface mission. Exceeding a 1970-era Apollo milestone carries symbolic weight, demonstrating that modern launch, spacecraft and mission-planning practices can safely move crew farther from Earth. Technically, the flight validates life-support, navigation and communications systems in a cislunar environment and provides directly observed optics and crew-performance data that automated instruments alone cannot supply.
Operationally, the mission’s success will feed into risk assessments, procedures, and hardware modifications before Artemis missions aimed at lunar surface return. Imagery and crew observations will refine landing-site selection models and hazard maps for future surface missions; engineers will analyze data for thermal cycling effects, radiation exposure records, and communications handoff performance during the moon occultation period. Each dataset reduces uncertainty for the next crewed Artemis flights that will test human-robotic surface operations and habitation concepts.
Strategically, the mission reinforces international partnerships by placing a Canadian astronaut on a milestone flight and by coordinating global tracking and recovery assets. Politically, the record helps sustain public and congressional attention on space program funding debates; scientifically, the mission expands the catalog of high-resolution, oblique lighting images of lunar terrain that can inform geology and resource-assessment studies.
Comparison & data
| Mission | Date | Peak distance from Earth (miles) |
|---|---|---|
| Apollo 13 | April 1970 | 248,655 |
| Artemis II (outbound reported) | April 6, 2026 | 248,655 (surpassed); peak ~252,756 |
The table contrasts the long-standing Apollo 13 benchmark with Artemis II figures. Apollo 13’s record of 248,655 miles stood for more than 56 years; Artemis II was reported at the same 248,655-mile mark at the stated observation time and is expected to reach roughly 252,756 miles at its outbound apex. Engineers will compare navigation solution residuals, thermal profiles and radiation dosimetry from both missions to refine future deep-space crewed trajectories.

Unconfirmed
- Specific phrasing and scope of changes NASA made to statements about crew accomplishments were adjusted in the April 6 update; detailed rationale was not fully itemized in the public release.
- The informal crater-name proposals will only be official if accepted by the IAU; approval is not guaranteed and has not been granted at this time.
Bottom line
Artemis II’s outbound leg has set a new benchmark for how far humans have traveled from Earth, demonstrating the Artemis architecture’s capability to operate in the deep-space environment and producing datasets that will directly shape future lunar missions. The flight remains a test campaign: successes and anomalies alike will inform design, procedures and planning for Artemis missions intended to return humans to the lunar surface and eventually enable crewed Mars missions.
Over the coming days, engineers will analyze telemetry, imagery and crew health data while recovery teams prepare splashdown operations off San Diego on April 10. The mission’s combination of technical validation, international partnership and symbolic achievement reinforces the program’s stated objective to expand sustained human presence beyond low Earth orbit.
