VANDENBERG SPACE FORCE BASE, Calif. (NASA PR) — NASA’s Double Asteroid Redirection Test (DART), the world’s first full-scale mission to test technology for defending Earth against potential asteroid or comet hazards, launched Wednesday at 1:21 a.m. EST on a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California.
Just one part of NASA’s larger planetary defense strategy, DART – built and managed by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland – will impact a known asteroid that is not a threat to Earth. Its goal is to slightly change the asteroid’s motion in a way that can be accurately measured using ground-based telescopes.
Editor’s Note: DART is scheduled to launch from Vandenberg on Nov. 23 at 10:21 p.m. PST (Nov. 24 at 1:21 a.m. EST). NASA will stream the launch live on its website.

It sounds like a plot for a movie but protecting Earth from a potential impact by a hazardous asteroid is the objective of an upcoming NASA mission.
The Double Asteroid Redirection Test (DART) mission is a planetary defense-driven test of technologies for mitigating such a threat. DART’s target asteroid is not a threat to Earth. The DART spacecraft launch window opens Nov. 24. It will launch aboard a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California.
KENNEDY SPACE CENTER, Fla. (NASA PR) — NASA is inviting the public to take part in virtual activities and events ahead of the launch of the agency’s Laser Communications Relay Demonstration (LCRD) mission. Launch is scheduled for 4:04 – 6:04 a.m. EST on Saturday, Dec. 4, 2021, aboard a United Launch Alliance Atlas V 551 rocket from Space Launch Complex 41 at Cape Canaveral Space Force Station, Florida.
Recently downlinked imagery of a September flight has allowed the rover imaging team to put together a video of rotorcraft performing to near-perfection.
PASADENA, Calif. (NASA PR) — Video footage from NASA’s Perseverance Mars rover of the Ingenuity Mars Helicopter’s 13th flight on Sept. 4 provides the most detailed look yet of the rotorcraft in action.
HOUSTON (NASA PR) — NASA has awarded Intuitive Machines of Houston a contract to deliver research, including science investigations and a technology demonstration, to the Moon in 2024. The commercial delivery is part of NASA’s Commercial Lunar Payload Services (CLPS) initiative and the Artemis program.
VANDENBERG SPACE FORCE BASE, Calif. (NASA PR) — NASA will provide coverage of the upcoming prelaunch and launch activities for the agency’s first planetary defense test mission, the Double Asteroid Redirection Test (DART). The mission will help determine if intentionally crashing a spacecraft into an asteroid is an effective way to change its course. DART’s target asteroid is not a threat to Earth.
DART is scheduled to launch no earlier than 1:20 a.m. EST Wednesday, Nov. 24 (10:20 p.m. PST Tuesday, Nov. 23) on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.
Earth’s atmosphere reacted in surprising ways to the lowering of emissions during the pandemic, showing how closely climate warming and air pollution are linked.
PASADENA, Calif. (NASA PR) — The COVID-19 pandemic and resulting limitations on travel and other economic sectors by countries around the globe drastically decreased air pollution and greenhouse gas emissions within just a few weeks. That sudden change gave scientists an unprecedented view of results that would take regulations years to achieve.

With conjunction over and our first flight at 2,700 RPM behind us, Ingenuity is ready to begin the journey back to the Wright Brothers Field at the Octavia E. Butler landing site, before venturing beyond. The above figure depicts the mission ahead of Ingenuity, which is to join Perseverance in the trek north along the east edge of Séítah, before traveling west to reach the Jezero ancient river delta. To accomplish this feat, the Ingenuity team is planning a series of 4-7 flights to return to Wright Brothers Field. Along the way the project is considering preparing a flight software upgrade for our helicopter which will potentially enable new navigation capabilities onboard, and better prepare Ingenuity for the challenges ahead.
WASHINGTON (NASA PR) — NASA has selected a new Earth science mission that will study the behavior of tropical storms and thunderstorms, including their impacts on weather and climate models. The mission will be a collection of three SmallSats, flying in tight coordination, called Investigation of Convective Updrafts (INCUS), and is expected to launch in 2027 as part of NASA’s Earth Venture Program.
PASADENA, Calif. (NASA PR) — A new study shows how the chemicals in an exoplanet’s atmosphere can, in some cases, reveal whether or not the temperature on its surface is too hot for liquid water.
In our solar system, planets are either small and rocky (like Earth) or large and gaseous (like Neptune). But around other stars, astronomers have found planets that fall in between – worlds slightly larger than Earth but smaller than Neptune. These planets may have rocky surfaces or liquid-water oceans, but most are likely to be topped with atmospheres that are many times thicker than Earth’s and opaque.
PASADENA, Calif. (NASA PR) — New findings from NASA’s Juno probe orbiting Jupiter provide a fuller picture of how the planet’s distinctive and colorful atmospheric features offer clues about the unseen processes below its clouds. The results highlight the inner workings of the belts and zones of clouds encircling Jupiter, as well as its polar cyclones and even the Great Red Spot.
NASA is looking into whether mixed reality technology could help with repairs and upgrades on the cutting-edge Cold Atom Lab aboard the space station.
PASADENA, Calif. (NASA PR) — NASA’s Cold Atom Lab is a first-of-its-kind physics laboratory operating in Earth orbit. About the size of a mini-fridge, it hosts multiple experiments that explore the fundamental nature of atoms by cooling them down to nearly absolute zero (the coldest temperature matter can reach). The ultracold atoms provide a window into the quantum realm, where matter exhibits strange behaviors that underpin many modern technologies.
VANDENBERG SPACE FORCE BASE, Calif. (NASA PR) — Just two days after leaving the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, in a specialized container carefully strapped to the deck of a semi-trailer truck, NASA’s Double Asteroid Redirection Test (DART) spacecraft arrived in California — its final stop here on Earth.
The truck, spacecraft and a small motorcade of APL engineers and technicians pulled into Vandenberg Space Force Base near Lompoc, California, on Saturday, Oct. 2, in the early afternoon local time.
Two microphones aboard the six-wheeled spacecraft add a new dimension to the way scientists and engineers explore the Red Planet.
PASADENA, Calif. (NASA PR) — Thanks to two microphones aboard NASA’s Perseverance rover, the mission has recorded nearly five hours of Martian wind gusts, rover wheels crunching over gravel, and motors whirring as the spacecraft moves its arm. These sounds allow scientists and engineers to experience the Red Planet in new ways – and everyone is invited to listen in.
NASA, along with the European Space Agency, is developing a campaign to return the Martian samples to Earth.
GREENBELT, Md. (NASA PR) — On Sept. 1, NASA’s Perseverance rover unfurled its arm, placed a drill bit at the Martian surface, and drilled about 2 inches, or 6 centimeters, down to extract a rock core. The rover later sealed the rock core in its tube. This historic event marked the first time a spacecraft packed up a rock sample from another planet that could be returned to Earth by future spacecraft.
