Voyager at 45: NASA’s Longest and Farthest Explorers (Live Q&A)
Launched in 1977, the twin Voyager probes are NASA’s longest-operating mission and the only spacecraft ever to explore interstellar space. For two decades after launch, the spacecraft were planetary explorers, giving us up-close views of the gas giants Jupiter, Saturn, Uranus, and Neptune. Now, as they reach distances far beyond the hopes of their original designers, the aging spacecraft challenge their team in new ways, requiring creative solutions to keep them operating and sending back science data from the space between the stars. As we celebrate the 45th anniversary of these epic explorers, join Voyager deputy project scientist Linda Spilker and propulsion engineer Todd Barber for a live Q&A.

How Will We Know if NASA’s DART Mission Successfully Changed an Asteroid’s Orbit?
NASA’s Double Asteroid Redirection Test, also known as DART, is humanity’s first attempt to change the motion of a non-hazardous asteroid in space by intentionally crashing a spacecraft into it. After impact, ground-based observatories across the globe will turn their eyes to the skies to determine if this planetary defense test was successful. In this video, NASA visits Lowell Observatory to learn more about how astronomers have been tracking this double asteroid over the course of many years, and how they will document the orbital change post-impact. DART is a spacecraft designed to impact an asteroid as a test of technology. DART’s target asteroid is NOT a threat to Earth. This asteroid system is a perfect testing ground to see if intentionally crashing a spacecraft into an asteroid is an effective way to change its course, should a hazardous asteroid be discovered in the future.

Perseverance Explores the Jezero Crater Delta
NASA’s Perseverance Mars Rover has arrived at an ancient delta in Jezero Crater, one of the best places on the Red Planet to search for potential signs of ancient life. The delta is an area where scientists surmise that a river once flowed billions of years ago into a lake and deposited sediments in a fan shape. Rachel Kronyak, a member of the Perseverance science operations team, guides the viewer through this Martian panorama and its intriguing sedimentary rocks. It’s the most detailed view ever returned from the Martian surface, consisting of 2.5 billion pixels and generated from 1,118 individual Mastcam-Z images. Those images were acquired on June 12, 13, 16, 17, and 20, 2022 (the 466th, 467th, 470th, 471st, and 474th Martian day, or sol, of Perseverance’s mission). In this panorama, an area called Hogwallow Flats is visible, as is Skinner Ridge, where two rock core samples were taken. The color enhancement in this image improves the visual contrast and accentuates color differences. This makes it easier for the science team to use their everyday experience to interpret the landscape. For more information on the Perseverance rover, visit https://mars.nasa.gov/perseverance.

Hear Meteoroid Striking Mars, Captured by NASA’s InSight Lander
NASA’s InSight lander detected seismic waves from a meteoroid and was able to capture the sound of the space rock striking the surface of Mars for the first time. The meteoroid – the term used for incoming space rocks before they hit the ground – entered Mars’ atmosphere on Sept. 5, 2021, exploding into at least three shards that each left craters behind. Mars’ atmosphere is just 1% as dense as Earth’s, allowing far more meteoroids to pass through and impact the Red Planet’s surface. This event marks the first time seismic and acoustic waves from an impact were detected on the Red Planet. Why does this meteoroid impact sound like a “bloop” in the video? It has to do with a peculiar atmospheric effect that’s also observed in deserts on Earth. After sunset, the atmosphere retains some heat accumulated during the day. Sound waves travel through this heated atmosphere at different speeds, depending on their frequency. As a result, lower-pitched sounds arrive before high-pitched sounds. An observer close to the impact would hear a “bang,” while someone many miles away would hear the bass sounds first, creating a “bloop.” NASA’s Mars Reconnaissance Orbiter flew over the estimated impact site to confirm the location. The orbiter used its black-and-white Context Camera to reveal three darkened spots on the surface. After locating these spots, the orbiter’s team used the High-Resolution Imaging Science Experiment camera, or HiRISE, to get a color close-up of the craters. Because HiRISE sees wavelengths the human eye can’t detect, scientists change the camera’s filters to enhance the color of the image. The areas that appear blue around the craters are where dust has been removed or disturbed by the blast of the impact. Martian dust is bright and red, so removing it makes the surface appear relatively dark and blue. For more information on InSight, visit https://mars.nasa.gov/insight.

Lucy Spacecraft Will Slingshot Around Earth
NASA’s Lucy mission is heading to the Jupiter Trojans – two swarms of primitive asteroids trapped in Jupiter’s orbit that may hold clues to the formation of the planets. Lucy launched on October 16, 2021. After a year in orbit around the Sun, it is returning home on its launch anniversary for the first of three Earth gravity assists. On October 16, 2022, Lucy will fly by the Earth like a partner in a swing dance, boosting its speed and elongating its orbit around the Sun. At 7:04 am, Eastern Time, Lucy will make its closest approach at just 219 miles above the planet: lower than the International Space Station. This exceptionally close shave will increase its velocity by four-and-a-half miles per second, setting Lucy on track to gain even more speed when it returns to Earth for its second gravity assist in December 2024.

NASA Explorers Season 5, Episode 4: The South Pole
When Artemis astronauts land on the Moon, they’ll travel to sites never before visited by humans. Namely, they'll explore the South Pole region, home to the Moon’s largest crater, areas of near-constant light and deep shadows, and some of the coldest temperatures in the solar system. Exploring the South Pole will teach us more about the Moon’s history, as well as the history of our solar system. It's home to frozen water, which is crucial for living sustainably on the lunar surface and exploring deeper into the solar system. Artemis astronauts will explore the Moon on behalf of all of us and bring back lunar rocks and soil for analyses by generations of scientists who will help us gain unimaginable insights into our cosmic history.

Cosmic Dust Rings Spotted by NASA’s James Webb Space Telescope
An image from NASA’s James Webb Space Telescope reveals a remarkable sight: at least 17 concentric dust rings emanating from a pair of stars located about 5,300 light-years from Earth. Each ring was created when the stars came close together and their colliding stellar winds (streams of gas they blow into space) caused some of the gas to compress into dust. Collectively known as Wolf-Rayet 140, the stars’ orbits bring them together about once every eight years, so just like the growth rings of a tree trunk, these dusty loops mark the passage of time: The 17 rings reveal more than a century of stellar interactions. And while other Wolf-Rayet stars produce dust, no other pair is known to produce rings quite like Wolf-Rayet 140. Because the stars’ orbits are elliptical rather than circular, the distance between the stars changes constantly, and dust forms only when they are close. The amount of dust produced by this interaction varies, so the system doesn’t form a perfect bullseye. One of the densest regions of dust production creates the bright feature repeating at 2 o’clock.

Hubble Views Aftermath of DART Impact
The DART mission deployed a kinetic impactor to smack the small moon Dimorphos of the asteroid Didymos on the evening of Sept. 26. This was an on-orbit demonstration of asteroid deflection, a key test of NASA's kinetic impactor technology, designed to impact an asteroid to adjust its speed and path. This particular asteroid moon is NOT a threat to Earth, but is technology being explored to use for when we DO find a potentially hazardous asteroid. The Hubble Space Telescope captured these extraordinary views of the asteroid moon soon after the successful impact. For more information, visit https://nasa.gov/hubble.

How NASA Sees the Life Cycle of Volcanic Island Hunga Tonga-Hunga Ha’apai
When the Hunga Tonga-Hunga Ha’apai volcano erupted on Jan. 15, it sent a tsunami racing around the world and set off a sonic boom that circled the globe twice. The underwater eruption in the South Pacific Ocean also blasted an enormous plume of water vapor into Earth’s stratosphere – enough to fill more than 58,000 Olympic-size swimming pools. The sheer amount of water vapor could be enough to temporarily affect Earth’s global average temperature. So outside of its sheer magnitude, what makes this eruption so unique? Well, it’s really a matter of our ability to see it through NASA and ESA satellites.

NASA Tests Ways to Crash Land on Mars
We’re testing a new way of landing on Mars… by crashing into its surface. The Simplified High Impact Energy Landing Device (SHIELD) is a lander concept being tested at NASA’s Jet Propulsion Laboratory (JPL). It could one day provide a new way for low-cost missions to land on Mars. Rather than rely on parachutes or retrorockets, SHIELD would include a collapsible, accordion-like base to absorb the energy of a landing. A full-size prototype of the base was tested on Aug. 12, 2022. The prototype was hurled at the ground from the top of a nearly 90-foot-tall (27-meter-tall) drop tower at JPL. A steel plate ensured the impact was even harder than what would be experienced on Mars. The design worked: After crushing against the steel plate at 110 mph (177 kph), several electronic components inside the SHIELD prototype, including a smartphone, survived the impact.

NEOWISE: Revealing Changes in the Universe
New time-lapse movies from NASA’s NEOWISE mission give astronomers the opportunity to see objects, like stars and black holes, as they move and change over time. The videos include previously hidden brown dwarfs, a feeding black hole, a dying star, a star-forming region, and a brightening star. They combine more than 10 years of NEOWISE observations and 18 all-sky images, enabling a long-term analysis and a deeper understanding of the universe. 0:44 – NEOWISE all-sky scan animation 1:03 – Feeding black hole 1:14 – Pulsing star reaches the end of its life 1:21 – Protostars in star-forming region 1:34 – Brown dwarf moves across the sky 2:00 – Unexplained stellar brightening The NEOWISE mission uses a space telescope to hunt for asteroids and comets, including those that could pose a threat to Earth. Launched in December 2009 as the Wide-Field Infrared Survey Explorer, or WISE, the space telescope was originally designed to survey the sky in infrared, detecting asteroids, stars and some of the faintest galaxies in space. WISE did so successfully until completing its primary mission in February 2011. Observations resumed in December 2013, when the telescope was taken out of hibernation and re-purposed for the NEOWISE project as an instrument to study near-Earth objects, or NEOs, as well as more distant asteroids and comets.

SWOT: Earth Science Satellite Will Help Communities Plan for a Better Future
A new Earth science mission, led by NASA and the French space agency Centre National d’Études Spatiales (CNES), will help communities plan for a better future by surveying the planet’s salt and freshwater bodies. The Surface Water and Ocean Topography (SWOT) mission will measure the height of water in lakes, rivers, reservoirs, and the oceans. As climate change accelerates the water cycle, more communities around the world will be inundated with water while others won’t have enough. SWOT data will be used to improve flood forecasts and monitor drought conditions, providing essential information to water management agencies, civil engineers, universities, the U.S. Department of Defense, disaster preparedness agencies, and others who need to track water in their local areas. In this video, examples of how SWOT data will be used in these communities are shared by a National Weather Service representative in Oregon, an Alaska Department of Transportation engineer, researchers from the University of Oregon and University of North Carolina, a NASA Jet Propulsion Laboratory scientist working with the Department of Defense, and a JPL scientist working with the Louisiana Coastal Protection and Restoration Agency. :30 - Flood Watches & Warnings - Portland, Oregon 1:08 - Water Management - Fern Ridge Lake, Oregon 2:05 - Protecting Infrastructure - Alaska 2:54 - National Security - Department of Defense 3:24 - Coastal Protection - Mississippi River Delta SWOT is expected to launch from Vandenberg Space Force Base in California in December 2022.
