Guide a ship to dock at the International Space Station

SpaceX's Crew Dragon was the first crewed spacecraft piloted by touchscreen

In May 2020, NASA astronauts flying SpaceX's Crew Dragon to the International Space Station used touchscreen controls instead of traditional switches and dials, a significant shift for astronauts and how they pilot and interact with spacecraft. (Some users may experience a paywall.)

View the docket of future SpaceX launches

SpaceX has established an efficient schedule for launches of ISS crew shuttles and Starlink satellites, with blastoffs occurring just under once every four days in 2023—a pace that has since accelerated as the company has won more contracts.

Take a virtual tour of the International Space Station

The ISS is the largest human-made object in space. Its modules were meticulously connected by robotic arms and astronauts during slow, careful spacewalks, creating a structure with over eight miles of electrical wire.

Most elements of the International Space Station were installed over two decades

Space shuttles delivered storage carriers, docking compartments, airlocks, solar arrays, and labs, which were assembled in low Earth orbit. The station’s Canadarm2 robotic arm, alongside maneuvering spacewalkers, has assisted with this assembly since its installation in 2001.

Starship is the space travel ship that rides atop the world's largest rocket

SpaceX hopes to use the vehicle for both interplanetary travel and shorter flights around Earth. At 30 feet wide, it allows for more storage and headspace for inhabitants than previous NASA spacecraft.

Watch what it’s like to spend a day on the International Space Station

Microgravity makes personal care more complex on the International Space Station, where stray, floating materials must be captured to prevent them from entering vents and clogging filtration vents. No-rinse shampoo, water pouches, and other strategies help minimize obstructions.

When retired, the International Space Station will undergo a controlled de-orbit

With plans to transition low-Earth orbit operations to private entities, the ISS is expected to be retired by 2030, using a SpaceX de-orbit vehicle. Although reentry will burn up most hardware, NASA intends for any surviving debris to fall into an uninhabited ocean area.

Explore a timeline of the International Space Station National Lab

In 1984, President Ronald Reagan called for establishing a human presence in space, which began with NASA astronaut Bill Shepherd and Russian cosmonauts Yuri Gidzenko and Sergei Krikalev on November 2, 2000. Humans have continuously occupied the ISS every day since.

Visitors of the International Space Station are trained in English and Russian

Different space agencies develop different modules of the ISS, meaning their controls, documentation, and instrumentation are not always written in English. Because the first modules were delivered using US and Russian spacecraft, astronauts have been historically trained in both languages.

Astrobee is a free-floating robotic system helping with routine tasks on the ISS

Three cube-shaped robots use electric fans to fly through the microgravity environment of the International Space Station. They are equipped with cameras and sensors that allow them to "see" and navigate their surroundings to take inventory, document experiments, and move cargo.

NASA and SpaceX combine public support and funding with private enterprise

Rather than competitors, SpaceX and NASA are mutually beneficial collaborators. Without NASA contracts, SpaceX may have run out of funding, and without the low-cost tech of SpaceX, NASA may have been left without a US-based launch system.

How to make a burrito in space

Just because you’re living at the International Space Station doesn’t mean your cravings disappear. In this video, Chef Traci Des Jardins explains the best way to make a burrito while experiencing microgravity.

Gravity assists are crucial for space travel beyond Mars

By traveling near a moving celestial object, a passing object can gain or lose speed and change direction due to the acceleration provided by their mutual gravity. Some missions are planned around spacecraft performing multiple assists, or slingshots, to reduce fuel requirements for long-distance travel.

Deep Space Network sites enable nonstop communication with distant spacecraft

Each DSN complex has multiple large, sensitive antennas that can receive weak radio signals from far-off spacecraft and send commands back to them. Their amplifiers are cooled to just above absolute zero to reduce electronic noise.
