Canadian astronaut and commander of Expedition 35 answers a question about how astronauts brush their teeth in space. You might be surprised by what he reveals!

On March 8, 2019, the SpaceX Crew Dragon spacecraft undocks from the international space station, after nearly 5 days aboard the orbiting laboratory during the company's Demo-1 mission for NASA's commercial Crew program and descends to re-enter the Earth's atmosphere. Just over 5 hours later, the unscrewed spacecraft splashes down in the Atlantic ocean off the coast of Florida and is recovered by SpaceX teams.

In this video astronaut Chris Hadfield how us how to vomit in space station...

Water in space behaves… differently. Surface tension and capillary flow can be harnessed to move fluids in more efficient ways. What looks like fun could actually help us improve systems for moving fluids in microgravity, in things like fuel tanks for space travel.

Science gets scaled up with the first 8K ultra high definition (UHD) video from the International Space Station. Get closer to the in-space experience and see how the international partnership-powered human spaceflight is improving lives on Earth, while enabling humanity to explore the universe.

Parkinson’s disease affects more than 5 million people on Earth. Research on the International Space Station could provide insight into this chronic neurodegenerative disease and help scientists find ways to treat and prevent it. In this video, NASA astronaut Serena Auñon-Chancellor narrates as European Space Agency (ESA) astronaut Alexander Gerst uses a microscope to examine and photograph the LRRK2 crystals.

Tour of the Moon in all-new 4K resolution, thanks to data provided by NASA's Lunar Reconnaissance Orbiter spacecraft. As the visualization moves around the near side, far side, north and south poles, we highlight interesting features, sites, and information gathered on the lunar terrain.

For Earth Day 2021, we explore the connections of Earth systems and NASA's ability to observe them in a changing world, highlighting the links between dust transport, vegetation, water quality, conservation and human health, the cryosphere, and disasters.

While Apollo placed the first steps on the Moon, Artemis opens the door for humanity to sustainably work and live on another world for the first time. Using the lunar surface as a proving ground for living on Mars, this next chapter in exploration will forever establish our presence in the stars. We are returning to the Moon – to stay – and this is how we are going! Actress Kelly Marie Tran of “Star Wars: The Rise of Skywalker” lent her voice to this project.

NASA’s Lucy mission tests the deployment of its solar arrays in the thermal vacuum chamber at Lockheed Martin Space in Littleton, Colorado. Each of the two circular arrays is nearly 24 feet (7.3 m) wide. These arrays will power Lucy on its 12-year odyssey through the Jupiter Trojan asteroids, breaking records for a solar powered mission by traveling 530 million miles (853 million km) from the Sun. These large arrays will capture the sunlight needed to power the spacecraft as it travels through deep space.

101955 Bennu is one of Earth’s closest planetary neighbors – an asteroid roughly the height of a skyscraper, and since late 2018, the place that NASA’s OSIRIS-REx mission has called home. When OSIRIS-REx arrived on Dec. 3, 2018, it began wrapping Bennu in a complex web of observations. OSIRIS-REx departs Bennu on May 10, 2021, on a return voyage to Earth, bringing with it over 60 grams of sample collected from the asteroid. This narrated video presents the mission’s complete trajectory during its time at Bennu.

Dynamics Observatory — SDO — has now been watching the Sun non-stop for over a full decade. From its orbit in space around the Earth, SDO has gathered 425 million high-resolution images of the Sun, amassing 20 million gigabytes of data over the past 10 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system. With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds. The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at 10 different wavelengths of light. This 10-year time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength that shows the Sun’s outermost atmospheric layer — the corona. Compiling one photo every hour, the movie condenses a decade of the Sun into 61 minutes. The video shows the rise and fall in activity that occurs as part of the Sun’s 11-year solar cycle and notable events, like transiting planets and eruptions. The custom music, titled “Solar Observer,” was composed by musician Lars Leonhard.

The people who get to see the Earth from space marvel at its beauty, the colors, the fragility they feel about the planet 250 miles below them. Now it’s your turn: this ultra-high definition video, captured during the International Space Station’s Expedition 65, allows you an extended, appreciative gawk at the home planet in all its glory. Hit play, and go into orbit mode. This footage was shot from the International Space Station between April 17, 2021 – Oct. 17, 2021.

In this artist’s rendition, we explore a metallic world named Psyche, an asteroid that offers a unique window into the building blocks of planet formation. The NASA Psyche mission launches in 2023 and will arrive at the asteroid Psyche, which orbits the Sun between Mars and Jupiter, in 2026. The spacecraft, also named Psyche, will spend 21 months orbiting the asteroid, mapping it and studying its properties. The mission is led by Principal Investigator Lindy Elkins-Tanton of Arizona State University. NASA’s Jet Propulsion Laboratory is responsible for the mission’s overall management, system engineering, integration and test, and mission operations. Maxar Technologies is providing a high-power solar electric propulsion spacecraft chassis.
