The uncrewed Northrop Grumman Cygnus XL spacecraft, the S.S. Steven R. Nagel, arrived at the International Space Station on Monday (April 13), bringing with it about 11,000 pounds of supplies.
Rise joined the Artemis 2 crew as a mascot of the moon, bearing 5.6 million names. But the mascot quickly took on a new meaning.

The next cargo run to the International Space Station arrived at the orbiting outpost midday on Monday.
Artemis 2's Victor Glover and Christina Koch are all smiles after splashdown.
The close pass of Apophis is nothing to fear. Will you be watching on Friday, April 13, 2029, when this asteroid glides across the sky?
The Artemis 2 mission to the moon beamed back some incredible photos, and we've rounded up the best ones.
Astronomers have uncovered evidence that two planets collided around a young star, revealing how giant impacts sculpt baby solar systems.
A rare stargazing spectacle will unfold on Friday, April 13, 2029, as the asteroid Apophis passes closer than satellites over Europe and Africa in a true once-in-a-lifetime event.

Artemis II completed a 10-day journey around the Moon, carrying humanity farther into space than it has gone in over 50 years.
Scientists outline how a once-in-a-century solar storm could disrupt the technology modern society depends on.
Since July 2025, the European Space Agency’s pair of Proba-3 satellites has already created 57 artificial solar eclipses. So far, the mission has collected more than 250 hours of high-resolution videos of the Sun’s atmosphere, called the corona. That’s the same amount of observing time as about 5000 total solar eclipse campaigns carried out on Earth.
(This is Part 2 of a series on neutrinos, Majorana fermions, and one of the strangest open questions in physics. Read Part 1 first.)
Every electronic device you have ever owned shares a critical weakness. Push it past roughly 200 degrees Celsius and it begins to fail. Your phone, your car's computer, the satellites orbiting above your head right now, all of them have the same thermal ceiling baked into their design. For decades, that ceiling has been one of the most stubborn walls in engineering. Now, a team at the University of Southern California may just have broken through it.
How does something come from nothing? It is perhaps the most profound question in all of science and one we still cannot fully answer. How did a barren, lifeless planet transform itself, over billions of years, into a world teeming with life? Where did it actually begin?
Look up at a full Moon on a clear night and you are staring at a face that has been punched, gouged, and battered for four billion years. Those dark patches are vast basins blasted open by impacts so colossal they reshaped a world. The lighter highlands are pocked and pitted, crater upon crater, each one a frozen record of a collision that happened long before humans walked the Earth. Unlike our own planet, the Moon has no weather to smooth things over, no rivers to fill the hollows and no wind to soften the edges. What hits it, stays.
Experience the Aug. 12, 2026 total solar eclipse from Spain and Iceland with festivals, spa sessions and skywatching events along the path of totality.
The Artemis 2 astronauts are back on Earth, and they've begun processing their historic moon mission. But it's still tough for them to put the experience into words.
On March 25, 1938, a 31-year-old physicist named Ettore Majorana bought a ticket for a ferry from Palermo to Naples. That night, before boarding, he sent a letter to Antonio Carrelli, director of the Naples Physics Institute:
On Episode 205 of This Week In Space, Rod Pyle and Tariq Malik discuss the flight of Artemis 2.
Northrop Grumman's second "Cygnus XL" cargo ship launched toward the International Space Station on Saturday morning (April 11).
NASA doesn't plan to rest on its laurels after the historic success of its Artemis 2 moon mission. Here are the agency's ambitious plans for Earth's nearest neighbor.
