Where Is Artemis II Right Now?
As of Flight Day 4 — Saturday, April 4, 2026 — the Orion spacecraft was approximately 169,000 miles from Earth and closing in on the Moon at a distance of about 110,700 miles. That’s a staggering number to wrap your head around. To put it simply: they’re already deeper into space than the vast majority of humans have ever traveled.
The crew started their day to the tune of Chappell Roan’s “Pink Pony Club”. A pop song in deep space. If that doesn’t make the cosmos feel a little more human, we don’t know what will.
And right now, on Flight Day 5 (Sunday, April 5), Mission Control woke them at noon to begin preparing for the big event — the lunar flyby on Monday, April 6.
Who Are the Four Astronauts on Board?
Let’s give credit where it’s due. These are the four people strapped inside a capsule hurtling toward the Moon:
- Reid Wiseman — Commander (NASA)
- Victor Glover — Pilot (NASA)
- Christina Koch — Mission Specialist (NASA)
- Jeremy Hansen — Mission Specialist (Canadian Space Agency)
This crew is making history on multiple levels. Victor Glover is the first Black astronaut to fly beyond low-Earth orbit. Christina Koch already holds the record for the longest single spaceflight by a woman (328 days aboard the ISS). Jeremy Hansen is the first Canadian to leave Earth’s orbit.
They aren’t just astronauts. They’re trailblazers. And we’re watching it happen in real time.
What Happened During the Manual Piloting Test?
One of the most exciting milestones of Flight Day 4 was the manual piloting demonstration. At 9:09 p.m. EDT, Christina Koch and Jeremy Hansen took turns flying the Orion spacecraft by hand .
For 41 minutes, they tested two different thruster modes:
- Six degrees of freedom — controlling movement in all directions (up, down, left, right, forward, backward) plus rotation along all three axes.
- Three degrees of freedom — controlling rotational movement only.
Think of it like this: six degrees of freedom is driving a car that can also fly and spin. Three degrees is flying a helicopter with limited controls. Both tests help engineers understand how Orion handles in deep space — far from the gravitational comfort blanket of Earth.
Commander Wiseman and Pilot Glover are scheduled to repeat the test on Flight Day 8, Wednesday, April 9 . NASA wants as many pilot perspectives as possible.
Why does this matter? Because if something goes wrong on a future mission — say, on the way to Mars — astronauts need to know exactly how this spacecraft responds to human hands. Every second of data counts.
What Will the Lunar Flyby Look Like?
This is the part that makes our hearts beat faster.
On Monday, April 6, the Artemis II crew will perform a six-hour lunar flyby starting at 2:45 p.m. EDT . During that window, Orion’s main cabin windows will point directly at the Moon, giving the crew an unobstructed view.
How Close Will They Get?
Orion will pass 4,066 miles from the lunar surface at closest approach, around 7:02 p.m. EDT . That’s very different from the Apollo missions, which flew roughly 70 miles above the surface .
At 4,066 miles out, the crew won’t see individual boulders. Instead, they’ll see something the Apollo astronauts never saw — the entire disk of the Moon at once, including regions near the north and south poles .
What Will They Study?
The crew trained in geology — both in classrooms and in Moon-like environments on Earth. During the flyby, they’ll photograph and describe :
- Impact craters — scars from billions of years of cosmic collisions
- Ancient lava flows — evidence of a once-volcanically active Moon
- Surface cracks and ridges — formed as the Moon slowly cooled and shrank over time
They’ll also note differences in color, brightness, and texture. These visual clues tell scientists what the surface is made of and how it formed .
It’s hands-on planetary science, performed by human eyes and human minds, 250,000 miles from home.
A Solar Eclipse Seen from Space?
Here’s something that genuinely takes our breath away.
Toward the end of the flyby, Orion, the Moon, and the Sun will align in such a way that the crew will witness a solar eclipse from deep space . The Sun will disappear behind the Moon for about an hour.
During that time, the crew will see a mostly dark Moon — a haunting, almost poetic sight. But there’s science hidden in that darkness. They’ll analyze the solar corona, the Sun’s outermost atmosphere, as it peeks around the Moon’s edge .
The corona is normally invisible to the naked eye because the Sun’s surface is so blindingly bright. A solar eclipse — whether from Earth or from space — is one of the rare moments when we can study it directly.
The crew will also look for flashes of light from meteoroids striking the lunar surface . These tiny impacts happen all the time, but catching them in real time gives NASA valuable data about potential hazards for future surface missions.
Will Artemis II Break Apollo 13’s Distance Record?
Yes. And it’s not even close.
During the flyby on Monday, Orion is expected to reach a maximum distance of 252,757 miles from Earth at approximately 7:05 p.m. EDT . That would surpass the record set by Apollo 13 — 248,655 miles — by 4,102 miles
| Mission | Year | Max Distance (miles) |
|---|---|---|
| Apollo 13 | 1970 | 248,655 |
| Artemis II | 2026 | 252,757 |
| Difference | +4,102 miles | |
Apollo 13, of course, never intended to set that record. Its trajectory was a desperate survival maneuver after an oxygen tank explosion in 1970. Fifty-six years later, Artemis II will claim that distance record on purpose — as part of a carefully planned mission.
That’s progress. And it feels good.
What Science Is Happening Inside Orion?
The flyby and piloting tests grab headlines. But some of the most important work on Artemis II is happening quietly, inside the capsule.
AVATAR Payload
The AVATAR experiment carries bone marrow cells derived from the crew’s own blood samples. Researchers want to understand how the human immune system reacts to deep-space radiation — something we still don’t fully understand. The payload is operating as expected.
Radiation Monitoring
The German Space Agency (DLR) provided multiple M-42 radiation sensors installed throughout Orion. Combined with NASA’s own measurements, these sensors are building a detailed map of radiation levels inside the spacecraft. This data will be essential for designing shielding on future long-duration missions — like trips to Mars.
Crew Health Tracking
Each astronaut wears actigraphy devices — small, watch-like sensors that collect health-related data. They also answer periodic questions about conditions on board. Together, this information (part of NASA’s Standard Measures and ARCHER programs) will help NASA improve crew efficiency on future flights.
Saliva Samples
The crew is also collecting saliva samples as part of an immune biomarkers study. It might not sound glamorous. But this is how we learn whether human bodies can survive — and thrive — on longer journeys through deep space.
How Is Laser Communication Changing Deep-Space Missions?
Here’s a number that should excite you: just after 12 p.m. EDT on Flight Day 4, the Orion Artemis II Optical Communications System surpassed 100 gigabytes of data downlinked during the mission . That includes high-resolution images.
How does it work? A terminal mounted on the outside of the Orion capsule uses infrared laser light to transmit data back to Earth . Laser communication can send far more information than traditional radio frequency systems.
Why does that matter? Picture future Moon bases streaming live video. Picture Mars missions sending back full-color panoramic images in real time instead of waiting hours for compressed, low-resolution files. That future starts with demonstrations like this one.
NASA is proving the concept right now, 170,000 miles from home.
What Challenges Has the Mission Faced So Far?
No space mission is perfect. That’s part of the deal. And Artemis II has had its share of small hiccups.
Wastewater Vent Line
Overnight before Flight Day 4, controllers vented wastewater overboard to free up space in Orion’s waste management system . But the activity ended earlier than expected. Engineers suspect a potential ice clog in the vent line and have been using vent heaters and orienting the vent toward the Sun to melt it .
The good news: the wastewater tank isn’t full, and the toilet is operational . The crew was told to use backup collection devices overnight as a precaution. It’s not glamorous, but it’s real. Space plumbing is hard.
Trajectory Corrections Cancelled — In a Good Way
Flight controllers cancelled another planned outbound trajectory correction burn because Orion’s trajectory remains on track . When your spacecraft is flying so precisely that it doesn’t need course corrections, that’s a win.
Communications Blackout
When Orion passes behind the Moon during Monday’s flyby, there will be a planned 40-minute communications blackout starting at approximately 5:47 p.m. EDT The Moon blocks radio signals between the Deep Space Network and the spacecraft. Similar blackouts happened during both Artemis I and the Apollo missions .
It’s expected. It’s planned for. But there’s something deeply human about knowing that for 40 minutes, four people will be completely alone — cut off from every other person alive — on the far side of the Moon.
Final Thoughts
We’re living through something extraordinary. Right now, four humans are racing toward the Moon in a spacecraft called Orion, and in just over 24 hours, they’ll fly past it — seeing its full face, watching a solar eclipse from deep space, and setting a new record for the farthest humans have ever traveled from home.
This isn’t science fiction. It’s Sunday, April 5, 2026. And it’s happening.
Artemis II represents more than a test flight. It’s a promise. A promise that we haven’t stopped reaching. That the Apollo program wasn’t a dead end — it was a beginning. And that the next chapter of human space exploration is being written right now, in real time, by four people waking up to pop music 169,000 miles from everything they’ve ever known.
