NASA @NASA 7:08 PM · Apr 3, 2026In this image, also taken from the Orion capsule, we see the divide between night and day, known as the terminator, cutting across Earth. Whether awake or dreaming, we're all here on this planet together.
These two images were taken by @astro_reid only minutes apart. The stark difference is the result of camera settings. In the first, a longer shutter speed let in much more light from Earth, while the shorter shutter speed in the second emphasizes our planet's nighttime glow.
Regardless of the exact lighting, there will be two opportunities to capture both the Earth and the moon in the same shot, explains Ernie Wright, a NASA senior data visualizer. “The plan is to view both Earthset and Earthrise,” Wright says in an email. The capsule will be traveling so fast, these two chances will occur only about 45 minutes apart, and happen when the capsule will be out of communication range with Houston on the far side of the moon. That 45 minutes is the only window they’ll get. Unlike during the Apollo missions, the Artemis II crew won’t enter lunar orbit and will pass around the moon just once.The Orion capsule has five windows—a docking window towards the top, and four forward-facing windows all on one side of the craft. It’s through one of these four main windows that the astronauts will snap the next Earthrise photo, says Kelsey Evans Young, lunar science lead for Artemis II. According to David Melendrez, the lead for Orion capsule imagery integration at NASA, the crew will use two handheld Nikon D5 DSLR cameras to get the image.Earthrise isn’t the only lunar imaging priority for the mission. In total, “we'll have three hours where the crew are taking pictures and just making verbal observations of the moon,” said Young. Because the human eye is much better at finding subtle color changes on the moon than robotic spacecraft, the crew have been tasked with photographing the surface extensively, as well as the impact flashes of meteorites that crash into the surface during their flyby.

Jonathan McDowell @planet4589 5:49 PM · Apr 3, 2026Three of the four Artemis-II cubesats have now been cataloged; orbits are 149 x 70247 km, 492 x 70228 km, and 61 x 70276 km. Suggests at least one made a successful perigee raising burn, but waiting for more data before drawing too many conclusions.
NASA Administrator Jared Isaacman @NASAAdmin 1:38 AM · Apr 4, 2026Artemis II successfully deployed 4 CubeSats in high Earth orbit. These satellites, developed with our Artemis Accords partners @DLR_en,@CONAE_Oficial, @with_KASA, and @saudispace , will demonstrate radiation research, space weather monitoring, and new technologies that will be critical to advancing future deep-space exploration.

Ta dzisiejsza fotka Ziemi to jest niesamowite cudo - jak zwraca się uwagę, Ziemię oświetla na tej fotce światło popielate od Księżyca. Świetnie widoczne mocne światła miast..
Chris Hadfield @Cmdr_Hadfield 6:47 PM · Apr 3, 2026Beautiful new whole-Earth photo. I love to zoom in and see the changing fine details, like the green glow of the aurora near the poles. A beauty of extreme exploration is that we better discover and understand our home.
Canadian Space Agency @csa_ascA proud Canadian moment: @astro_jenni on the ground, @astro_jeremy in space connect for the very first time since the launch of Artemis II. 🥹🇨🇦
Canadian Space Agency @csa_asc 1:30 PM · Apr 3, 2026We'll have 3 space-to-Earth connections with Jeremy Hansen in the next days. They will last approx. 20 minutes and will be livestreamed. These connections are made possible thanks to the Deep Space Network, which NASA uses to communicate with its spacecrafts.

In Good Spirits🇺🇸 @SoilOfHarvestJim Lovell said that he had trouble using the sextant for navigation because he kept confusing the vented urine with stars haha
NASA Artemis @NASAArtemis 2:54 AM · Apr 4, 2026Since everyone always asks... 🤔The universal waste management system aboard the Orion spacecraft is a compact, 5-cubic-foot toilet designed for microgravity. Solid waste is stored in odor-controlled canisters, while pre-treated urine is vented overboard daily.
Relief for astronauts as fault fixed on Nasa’s $30m Artemis II toiletHannah Devlin Science correspondent Thu 2 Apr 2026 18.24 CESTAnd despite the shaky start, the spacecraft’s $30m (£22.6m) Universal Waste Management System (UWMS) has been hailed as a leap forward in deep space toilet technology. The system was years in development and designed to improve on longstanding complaints from astronauts about onboard facilities.On the Apollo missions, astronauts were required to pee into a condom-like contraption placed under the spacesuit (all Apollo crew being male). Solid waste was collected into a bag taped to the astronaut’s buttocks.The setup was prone to leaks, with one mission transcript recording an alarmed crew member noticing “a turd floating through the air”. And while a Nasa report concluded that the primitive setup had broadly met its objectives from a purely engineering standpoint, it “must be given poor marks” for crew satisfaction.
K-RadCube launched with Artemis II misses normal contact, jeopardizing missionBy Hong A-reum Published 2026.04.03. 18:10 Updated 2026.04.03. 18:24K-RadCube in operation. /Courtesy of Korea AeroSpace AdministrationThe Korean CubeSat K-RadCube, launched together with the U.S. crewed lunar exploration mission Artemis II, failed to establish normal communications a day after liftoff.The Korea AeroSpace Administration and the Korea Astronomy and Space Science Institute (KASI) on the 3rd announced initial operations results for K-RadCube, saying they succeeded in receiving the satellite's signal in some passes but did not achieve normal communications, including securing observation data.K-RadCube was launched with Artemis II at 7:35 a.m. on the 2nd, Korea time, and separated at an altitude of about 40,000 km at 12:58 p.m. the same day. Afterward, the Korea AeroSpace Administration attempted initial communications using overseas ground station antennas.The first signal was detected around 2:30 p.m. on the 2nd at the Maspalomas ground station in Spain. Then at 9:57 p.m. the same day, the ground station in Hawaii in the United States received abnormal telemetry information from the satellite. Telemetry shows the satellite's status, and it was determined that the data expected to be received initially did not come in properly.This reception occurred at a distance of about 68,000 km from the satellite. The Korea AeroSpace Administration said that excluding the roughly 1.5 million km reception case of the lunar orbiter Danuri, this is the farthest distance at which a satellite signal has been received by Korea.The problem is that it remains unclear whether the mission has been carried out since then. K-RadCube was designed to fly along an elliptical orbit reaching up to 70,000 km in altitude and conduct a maneuver to raise its altitude at perigee, but it has not yet been confirmed whether that mission succeeded. If the altitude increase did not occur, the satellite could reenter Earth's atmosphere and disintegrate.The Korea Astronomy and Space Science Institute (KASI) is not completely ruling out the satellite's survivability and, together with operating agencies KT SAT and Nara Space, plans to continue initial operations and additional communication attempts until 12:30 p.m. on the 4th.K-RadCube's core objective is to measure space radiation in Earth's Van Allen radiation belts by altitude during the crewed lunar exploration process. Semiconductor devices from Samsung Electronics and SK hynix were also onboard to verify operation in the high-orbit radiation environment.Kang Gyeong-in, head of space science exploration at the Korea AeroSpace Administration, said, "Through international cooperation with NASA, K-RadCube, mounted on Artemis II, became the first case in Korea to receive a signal beyond geostationary orbit," adding, "It is significant that a CubeSat with private-sector participation accompanied an international crewed exploration mission, but it is regrettable that we could not secure observation data."
