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.

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.

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.

Emission Reductions From Pandemic Had Unexpected Effects on Atmosphere

Worldwide restrictions during the COVID-19 pandemic caused huge reductions in travel and other economic activities, resulting in lower emissions. Seen here, almost-empty highways in Colombia during the pandemic. (Credits: International Monetary Fund)

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.

Ingenuity Helicopter Flight #15 – Start of the Return Journey on Mars

Perseverance’s First Road Trip: This annotated image of Mars’ Jezero Crater depicts the route NASA’s Perseverance rover is taking during its first science campaign – as well as its path to the location of its second science campaign. Ingenuity will be tasked with joining Perseverance along this journey, with the goal of reaching Jezero’s river delta. (Credits: NASA/JPL-Caltech/University of Arizona)

Written by Teddy Tzanetos
Ingenuity Team Lead at NASA’s Jet Propulsion Laboratory

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.

How to Find Hidden Oceans on Distant Worlds? Use Chemistry

Planets that are between 1.7 and 3.5 times the diameter of Earth are sometimes called “sub-Neptunes.” There are no planets in this size range in Earth’s solar system, but scientists think many sub-Neptunes have thick atmospheres, potentially cloaking rocky surfaces or liquid oceans. (Credit: NASA/JPL-Caltech)

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.

Upgrading the Space Station’s Cold Atom Lab With Mixed Reality

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.

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.
