A rainbow patchwork quilt shows agriculture from space | Space photo of the day for June 4, 2026

This composite image uses NISAR data to show vegetation in the area around South Africa.

NISAR launched on July 28, 2025 on an Earth-observing mission. It tracks natural disasters and studies ecosystems, agriculture, glaciers and other facets of our planet's surface.In this image, you can see the region along the Vetrivier (Vet River, or "fat river") in South Africa. This area includes a wide-reaching agricultural region north of Bloemfontein. The data captured by NISAR in this image was used to create color-coded blocks that point to details like crop type.The Vetrivier flows through the Free State and North West provinces. This river feeds local agriculture, supporting crops across the wider Maize Triangle region, a major agricultural area in the country.Why is it incredible? This image is equal parts beauty and science. NISAR and other Earth-studying satellites are key players in our constantly evolving understanding of our planet.In the pretty abstract color blocks overlaid on this image, green points to an area with vegetation, red means an unvegetated area, and shades of blue depict how quickly a vegetated area changed within the recent season."It’s a pretty picture, but there are also important things that it communicates to us," Paul Siqueira, a scientist at the University of Massachusetts Amherst and the ecosystems lead of the NISAR science team, said in a statement. "With NISAR, crops like maize and sunflower appear differently than forests because of their size differences and period of growth."

China plans to double the size of its Tiangong space station while the ISS nears its end

China is set to expand its space station from three to six modules in the coming years and add a co-orbiting Hubble-class space observatory, even as the International Space Station approaches the end of its lifetime.The three-module, T-shaped Tiangong space station was assembled in orbit across 2021 and 2022 and has hosted numerous three-astronaut Shenzhou crews, but China is now set to expand the orbital outpost with new modules, citing growing research demands and more frequent crew and cargo missions. As previously reported by Space.com, the planned expansion will see Tiangong grow into a "double-T" shape, with the addition of the multipurpose module and two new experiment modules, and allow China to extend the scale of operations aboard the station."This expansion has always been part of the original plan," Qian Hang, a researcher with China Aerospace Science and Technology Corporation (CASC), told Chinese media. State media Xinhua reported that the first phase of the expansion will see the launch of a new 20-ton-class multifunctional module, which will dock with Tiangong's Tianhe core module.Additional docking ports on the new modules will allow Tiangong to welcome more spacecraft and provide greater operational flexibility when needed. "If the missions get more intensive, we risk 'queuing' for docking ports and lack sufficient emergency buffer space," Qian said.China is developing new, low-cost cargo options for Tiangong, while its new Mengzhou spacecraft, which could debut later this year, can carry seven astronauts to low Earth orbit. The Shenzhou spacecraft, which is currently used for China's crewed missions, can carry three astronauts to Tiangong.Before the arrival of a new module, however, the first new addition to Tiangong is expected to be Xuntian, a bus-sized space observatory with a 2-meter (6.6 feet) diameter primary mirror, slightly smaller than that of the Hubble Space Telescope.Xuntian is scheduled for launch in 2027 and boasts a field of view around 300 times larger than that of Hubble, meaning it will be able to study and map around 40% of the heavens during its planned 10-year lifetime using its 2.5-billion-pixel camera. Xuntian will share a similar orbit with Tiangong, meaning it will be able to dock with the space station for maintenance, refueling, repairs and potentially upgrades.

(Image credit: CCTV)China's plans to expand Tiangong are coming at the same time as NASA is planning for the end of life of the much larger International Space Station (ISS). The agency plans to launch the SpaceX-developed U.S. Deorbit Vehicle (USDV) in the coming years, and drag the ISS into the atmosphere over the Pacific Ocean in late 2030 or early 2031.While the U.S. is mulling a variety of plans for commercial stations that host astronauts in orbit after the ISS is retired, China would have the largest permanent outpost in orbit with Tiangong. According to Yang Hong, chief designer of the space station system, the planned expansion would take Tiangong from a mass of 90 tons to 180 tons.
