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.

Are Hurricanes Getting Stronger? We Asked a NASA Scientist
Are hurricanes getting stronger? Although we’ll never see a Category 6 hurricane, data does show that more hurricanes are becoming more severe. Hurricane and climate expert Mara Cordero-Fuentes of NASA's Goddard Space Flight Center tells us more about the connection between climate change and tropical cyclones.

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.

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.

133 Days on the Sun
solar activity from Aug. 12 to Dec. 22, 2022, as captured by NASA’s Solar Dynamics Observatory (SDO). From its orbit in space around Earth, SDO has steadily imaged the Sun in 4K x 4K resolution for nearly 13 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 133-day 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 images taken 108 seconds apart, the movie condenses 133 days, or about four months, of solar observations into 59 minutes. The video shows bright active regions passing across the face of the Sun as it rotates. The Sun rotates approximately once every 27 days. The loops extending above the bright regions are magnetic fields that have trapped hot, glowing plasma. These bright regions are also the source of solar flares, which appear as bright flashes as magnetic fields snap together in a process called magnetic reconnection. While SDO has kept an unblinking eye pointed toward the Sun, there have been a few moments it missed. Some of the dark frames in the video are caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun. Other blackouts are caused by instrumentation being down or data errors. SDO transmits 1.4 terabytes of data to the ground every day. The images where the Sun is off-center were observed when SDO was calibrating its instruments. SDO and other NASA missions will continue to watch our Sun in the years to come, providing further insights about our place in space and information to keep our astronauts and assets safe.

Video Description: On the left side of the frame is the full circle of the Sun. It appears in a golden yellow color, but splotchy and with thin yellow wisps extending from the surface. Some areas are very bright and others almost black. The whole Sun rotates steadily, with one full rotation taking 12 minutes in this time lapse. There are usually only a few bright regions visible at a time and they shift and flash like small fires. From these regions there are wispy loops reaching up above the surface that rapidly change shape and size. On the right side of the frame are two white-outlined squares with enlargements of interesting regions of the Sun.

How to Bring Mars Sample Tubes Safely to Earth (Mars News Report)
NASA’s Perseverance Mars rover is filling sample tubes with rocky material on the Red Planet as the agency works on the next steps to get them safely back to Earth. The Mars Sample Return campaign would bring samples collected by the Perseverance rover to Earth for detailed study. The campaign involves an international interplanetary relay team, including the European Space Agency (ESA). These samples could answer a key question: did life ever exist on Mars? Aaron Yazzie, who works on the Mars Sample Return campaign, explains the work being done at NASA’s Jet Propulsion Laboratory to ensure the safe return of the sample tubes.
