Science is starting for BioSentinel! 🛰️ Yeast cells are now getting warmed up and rehydrated for the first long duration biology experiment in deep space. Learn how this mission could help us better prepare astronauts for future space exploration: go.nasa.gov/3VODifb

25,000 mph ➡️ 20 mph During descent through Earth’s atmosphere, Orion Spacecraft must slow to a relatively gentle 20 mph for splashdown in the Pacific Ocean. Parachutes tested at our Silicon Valley center will help it do just that! See how to tune in: go.nasa.gov/3hatU6u

Today, President Donald J. Trump was greeted by NASA and California state leaders at Moffett Federal Airfield on his way to visit storm-damaged regions in the state. Learn how our research could help predict extreme climate-related weather events: go.nasa.gov/3QTHngj

LIVE NOW: #OTD one year ago, the NASA Webb Telescope telescope made it to its home 1 million miles away. How has it revolutionized our understanding of the cosmos since? Ask mission experts your questions on air, or tag them #UnfoldTheUniverse. x.com/NASA/status/16…

Punxsutawney Jake was startled by his shadow, too, on the first sunny morning after all that rain we had. So, whether you trust the rodent or the toddler: 6 more weeks of winter.Punxsutawney Jake was startled by his shadow, too, on the first sunny morning after all that rain…

Melba Roy Mouton—a NASA mathematician and key figure in the Apollo era—is being honored with the naming of a mountain on the Moon’s South Pole. Mons Mouton is the future landing site of VIPER, our rover set to explore the lunar surface for Artemis: go.nasa.gov/3xo4mHd #BHM

It’s usually best to keep your flight path “plane" and simple – complex cityscapes don’t always fly. 🚁 Our Data & Reasoning Fabric project aims to fix that. Drones backed by AI tools are being put to the test like never before. Learn how: go.nasa.gov/3xOwt2u

Next time, the Moon? 🌔 Jessica Watkins met our full-scale VIPER Moon rover model today! VIPER will search for water ice and other resources that could support future Artemis missions. #MoonRoverAndMe

Teamwork makes the dream work! Researchers at NASA Ames are creating tech to let small satellites work together—without being managed individually by mission controllers. One satellite swarm will fly this summer to test their work in our Starling mission. go.nasa.gov/45ZC5qF

Much of the world’s population could experience increases in severe heat stress. Fire weather in some regions will likely be more intense and last longer. Learn how NASA is analyzing the potential impacts of global temps rising beyond 2 degrees warming: go.nasa.gov/45kWYvk

Exploring the origins of Saturn’s rings and moons 🪐 New simulations show a massive collision may have led to the creation of the planet's iconic look. Learn more: go.nasa.gov/3ti6eCw

Today, NASA's current class of astronaut candidates toured our Ames Research Center's facilities. The visit included a stop at the Arc Jet Complex, where spacecraft thermal protection materials are tested. Learn more: go.nasa.gov/3QyGqtW

🏋️And weighing in at 121.6 grams is the largest asteroid sample ever collected in space! The goal was 60 grams, so the #OSIRISREx team more than doubled its mission requirement and has plenty to investigate the mysteries of the early solar system. go.nasa.gov/4bE7y4n

My name is on its way to the Moon aboard VIPER. 🌖🚀 You can send yours (your kid's, your mom's, your students'...), too! Closes March 15. go.nasa.gov/3S16kYf

Baby shark, doo-doo, doo-doo, doo-doo 🦈 Ocean wildlife tracking info + environmental data from satellites can help researchers understand how animal populations use their habitats and how that might shift as the climate changes. Learn more: go.nasa.gov/3xNMmKp

Sail deployment achieved! Our Advanced Composite Solar Sail System has successfully unfurled its sail & will use sunlight for propulsion as it orbits Earth, testing next-generation technologies that will help enable future missions at the Moon & beyond: go.nasa.gov/3XovKTm

We’re testing a new way to aid in fire response. NASA researchers attached wind sensors to a drone to provide more frequent and localized forecasts – called micrometeorology – that could help predict fire behavior. Learn more: go.nasa.gov/3EMKjZY

📢 Calling all innovators! NASA is making it easier than ever for small businesses to contribute their technology concepts to support NASA’s missions through a Broad Agency Announcement. The first three appendices, outlining topics and subtopics for desired technology
