    Tomorrow, June 25, NASA and CSA (Canadian Space Agency) leadership will discuss an upcoming spacewalk to repair the Canadarm2. What questions do you have about the spacewalk? Let us know below, then tune in tomorrow at 2 pm ET on plus.nasa.gov for the chance to hear it
     (Jan. 30, 2025) --- NASA astronaut and Expedition 72 Commander Suni Williams is attached to the Canadarm2 robotic arm's latching end effector while being maneuvered to her worksite 264 miles above the South Pacific Ocean. Williams removed and stowed a radio frequency group antenna assembly during the five-hour and 26-minute spacewalk outside the International Space Station.

    NASA astronauts Jessica Meir and Chris Williams, both Expedition 74 flight engineers, are pictured outside the International Space Station during a spacewalk to complete installation of a modification kit ahead of future solar array installation on the 2A power channel of the orbital outpost. It was William’s first spacewalk, Meir's fourth, and the 278th in support of space station maintenance, upgrades, and assembly.

    Summer looks good on Earth! 🏖️ From 250 miles up aboard the International @Space_Station, summer looks a little different. Shifting ocean colors, sunlit cloud tops, and the glow of the horizon show off the dynamic systems that shape our planet. Where is summer taking you?

    Artemis III crew 🤝 Orion Training is underway! The Artemis III astronauts have begun preparing for their mission, starting with familiarization of their spacecraft inside a full-scale Orion mockup at Johnson’s Space Vehicle Mockup Facility.
    NASA astronaut Frank Rubio, ESA (European Space Agency) astronaut Luca Parmitano, and NASA astronaut Randy Bresnik participate in one of their first Artemis III training courses.
    NASA astronauts Andre Douglas and Bob Hines participate in one of the first Artemis III training sessions.

    Shades of summer, seen from 250 miles up. 🌊 From the International @Space_Station, Earth’s blues stretch across coastlines, oceans, and islands in a way only astronauts get to see — a shifting palette shaped by sunlight, atmosphere, and the motion of our planet below. Will you
    ISS006-E-51456 (2003) --- Marias Islands, Mexico is featured in this image photographed by an Expedition Six crewmember on the International Space Station. The view shows the land-sea interactions along a section of Mexico's west coast just south of Mazatlan and the Isla Marias archipelago. The islands are a manifestation of intersecting plate boundaries -- the East Pacific Rise spreading center that traces south from the Gulf of California, and the subduction zone that consumes the Cocos plate beneath southern Mexico. These islands are biologically important: they comprise the Islas Marias Biosphere Reserve and contain endemic species of raccoons and rabbits, and important habitat for birds and marine life. Between the islands and the mainland, swirling surface currents are highlighted by the sun glint reflecting off the ocean surface. Along the Mexican coast, water flows out from a coastal lagoon, and near shore currents carry sediment (light colored water) along the beach front.
    ISS018-E-018129 (6 Jan. 2009) --- Atafu Atoll in the Southern Pacific Ocean is featured in this image photographed by an Expedition 18 crewmember on the International Space Station. At roughly eight kilometers wide, Atafu Atoll is the smallest of three atolls (with Nukunonu and Fakaofo atolls to the southeast, not shown) comprising the Tokelau Islands group located in the southern Pacific Ocean. Swains Island to the south (not shown) is also considered part of the Tokelau group. The political entity of Tokelau is currently a territory of New Zealand. In recent years, public referendums on independence within the islands have been held, but have not received sufficient support to move forward. The primary settlement on Atafu is a village located at the northwestern corner of the atoll ? indicated by an area of light gray dots in this photograph. The typical ring shape of the atoll is the result of coral reefs building up around a former volcanic island. Over geologic time, the central v
    ISS025-E-013475 (9 Nov. 2010) --- Parts of the Atlantic, Gulf of Mexico and Caribbean Sea are easily noted in this unusual circular shaped image exposed by one of the Expedition 25 crew members aboard the International Space Station 220 miles above Earth. A 16mm f/2.8D lens gives this image a fish-eye effect, and the frame of the Cupola window adds to the circular shape. The southern portion of the Florida peninsula, including the elongated metropolitan Miami area, Lake Okeechobee and the Florida Keys, lies just a few kilometers away from islands in the Bahamas chain and the "Tongue of the Ocean." Andros is the largest visible island to the left of center.
    ISS038-E-019899 (23 Dec. 2013) --- The Caribbean country of Cuba appears at the top of this high oblique image, photographed by one of the Expedition 38 crew members aboard the International Space Station. Andros Island, part of the Bahamas, is in the bottom of the frame. Cuba is an archipelago of islands in the northern Caribbean Sea at the confluence with the Gulf of Mexico and the Atlantic Ocean. A Russian Soyuz spacecraft is docked to the station.
