Seen during Artemis II’s lunar flyby on April 6, 2026, the Moon and Earth align in the same frame, each partially illuminated by the Sun. The Moon’s surface appears in sharp detail in the foreground, while Earth sits much farther away, smaller and softly lit in the background. A faint reflection in the spacecraft window is also visible, subtly overlaying the scene. Though their phases differ, both are shaped by the same sunlight, revealing the geometry of the Sun–Earth–Moon system from deep space.

NASA astronauts Reid Wiseman, Christina Koch, and Victor Glover, and CSA (Canadian Space Agency) astronaut Jeremy Hansen are set to return to Earth, splashing down in the Pacific Ocean around 8:07 p.m. EDT. Watch their return with NASA.

Space is getting crowded - and not just with satellites, but with the massive amounts of data they’re generating. The amount of information being generated and passed through orbit is exploding. From high-resolution Earth observation images to global maritime monitoring, it’s also become a critical link in our infrastructure. But there’s another space this growing crowd of satellites is dependent on that is also filling up fast - the radio frequency spectrum. If we want to keep expanding our orbital infrastructure, we need to rethink how we move data around. On March 30, 2026, the European Space Agency (ESA) supported a series of eight CubeSats and one specialized payload on SpaceX’s Transporter-16 rideshare mission with the overarching goals of testing high-throughput laser communication, inter-satellite networking, and in-orbit artificial intelligence processing to make space data transfer faster, more secure, and vastly more efficient.
