Description This 360-degree look at Neretva Vallis within Mars’ Jezero Crater was stitched together using 217 images acquired by the rover’s Mastcam-Z on May 20, 2024, the 1,155th Martian day, or sol, of the mission. While it is a wind-swept dusty vista today, billions of years ago it was home to a river channel that fed fresh water into […]

Written by Margaret Deahn, Ph.D. candidate at Purdue University Oct. 19, 2026 Once upon a time, NASA’s Mars 2020 rover investigated the southern border of “Idubi,” an outcrop composed primarily of an igneous mineral geologists call olivine. The rover’s “eyes” captured a very exciting geologic feature during its traverse — a contact between distinct rock […]

EVA
NASA astronaut Anil Menon and CSA astronaut Joshua Kutryk will exit the station’s Quest airlock to install and deploy an International Space Station Roll-Out Solar Array (IROSA) on the 2A electrical power channel. The solar array will be the seventh IROSA and will provide additional power to support critical station operations, including its safe and controlled deorbit.
EVA
NASA astronaut Anil Menon and CSA astronaut Joshua Kutryk will install and deploy the eighth and final IROSA on the 3B channel of the space station, completing the power augmentation upgrades. The final two roll-out solar arrays will complete the space station’s power system augmentation. Together, the eight roll-out arrays will increase available power by up to 30%, boosting the station’s electric power generation capacity from 160 kilowatts to approximately 215 kilowatts.
Orbital Insertion

The International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit. Its first component was launched into orbit in 1998, with the first long-term residents arriving in November 2000. It has been inhabited continuously since that date. The last pressurised module was fitted in 2011, and an experimental inflatable space habitat was added in 2016. The station is expected to operate until 2030. Development and assembly of the station continues, with several new elements scheduled for launch in 2019. The ISS is the largest human-made body in low Earth orbit and can often be seen with the naked eye from Earth. The ISS consists of pressurised habitation modules, structural trusses, solar arrays, radiators, docking ports, experiment bays and robotic arms. ISS components have been launched by Russian Proton and Soyuz rockets, and American Space Shuttles.

Mir was a space station that operated in low Earth orbit from 1986 to 2001, operated by the Soviet Union and later by Russia. Mir was the first modular space station and was assembled in orbit from 1986 to 1996. The station served as a microgravity research laboratory in which crews conducted experiments in biology, human biology, physics, astronomy, meteorology and spacecraft systems with a goal of developing technologies required for permanent occupation of space.

Skylab was a United States space station launched and operated by NASA, and occupied for about 24 weeks between May 1973 and February 1974 – the only space station the U.S. has operated exclusively. In 1979 it fell back to Earth amid huge worldwide media attention. Skylab included a workshop, a solar observatory, and other systems necessary for crew survival and scientific experiments. It was launched unmanned by a modified Saturn V rocket, with a weight of 170,000 pounds (77,000 kg). Lifting Skylab into low earth orbit was the final mission and launch of a Saturn V rocket (famous for carrying the manned Moon landing missions). Three missions delivered three-astronaut crews in the Apollo command and service module (Apollo CSM), launched by the smaller Saturn IB rocket. For the final two manned missions to Skylab, a backup Apollo CSM/Saturn IB was assembled and made ready in case an in-orbit rescue mission was needed, but this backup vehicle was never flown.
