Jovian Vortex Hunters Spun Up Over New Paper

NeRD

2 min read Jovian Vortex Hunters Spun Up Over New Paper Jumping Jupiter! The results are in, storm chasers! Thanks to your help over the last two years the Jovian Vortex Hunter project has published a catalog of 7222 vortices, which you can download here. Each vortex is an enormous swirling windstorm in Jupiter’s atmosphere–terrifying yet beautiful to behold. The vortices are labeled by color (“white” is most common, then “dark”, then “red”). The catalog reveals distributions of vortex sizes, aspect ratios, and locations on the planet. For example, your…

NASA DAVINCI Mission’s Many ‘Firsts’ to Unlock Venus’ Hidden Secrets

NeRD

5 Min Read NASA DAVINCI Mission’s Many ‘Firsts’ to Unlock Venus’ Hidden Secrets The surface of Venus is an inferno with temperatures hot enough to melt lead. This image is a composite of data from NASA’s Magellan spacecraft and Pioneer Venus Orbiter. Credits: NASA/JPL-Caltech NASA’s DAVINCI — Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging — mission embodies the spirit of innovation and exploration that its namesake, Leonardo da Vinci, was famous for. Scheduled to launch in the early 2030s, DAVINCI will explore Venus with both a spacecraft…

NASA Shares Asteroid Bennu Sample in Exchange with JAXA

NeRD

As part of an asteroid sample exchange, NASA has transferred to JAXA (Japan Aerospace Exploration Agency) a portion of the asteroid Bennu sample collected by the agency’s OSIRIS-REx mission. The sample was officially handed over by NASA officials during a ceremony on Aug. 22 at JAXA’s Sagamihara, Japan, campus. The signature exchange for the Bennu sample transfer took place on Aug. 22, 2024, at JAXA’s (Japan Aerospace Exploration Agency) Institute of Space and Astronautical Science, Sagamihara Campus. JAXA This asteroid sample transfer follows the November 2021 exchange where JAXA transferred…

New Evidence Adds to Findings Hinting at Network of Caves on Moon

NeRD

These images from NASA’s LRO spacecraft show a collection of pits detected on the Moon. Each image covers an area about 728 feet wide. An international team of scientists using data from NASA’s LRO (Lunar Reconnaissance Orbiter) has discovered evidence of caves beneath the Moon’s surface. In re-analyzing radar data collected by LRO’s Mini-RF (Miniature Radio-Frequency) instrument in 2010, the team found evidence of a cave extending more than 200 feet from the base of a pit. The pit is located 230 miles northeast of the first human landing site on…

Ongoing Venus Volcanic Activity Discovered With NASA’s Magellan Data

NeRD

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This computer-generated 3D model of Venus’ surface shows the volcano Sif Mons, which is exhibiting signs of ongoing activity. Using data from NASA’s Magellan mission, Italian researchers detected evidence of an eruption while the spacecraft orbited the planet in the early 1990s. NASA/JPL-Caltech An analysis of data from Magellan’s radar finds two volcanoes erupted in the early 1990s. This adds to the 2023 discovery of a different active volcano in Magellan data. Direct geological evidence of recent volcanic activity…

NASA’s LRO Finds Photo Op as It Zips Past SKorea’s Danuri Moon Orbiter

NeRD

NASA’s LRO (Lunar Reconnaissance Orbiter), which has been circling and studying the Moon for 15 years, captured several images of Korea Aerospace Research Institute’s Danuri lunar orbiter last month. The two spacecraft, traveling in nearly parallel orbits, zipped past each other in opposite directions between March 5 and 6, 2024. The dark spot centered in the bottom third of this image is the Korea Aerospace Research Institute’s Danuri orbiter, smudged because it was traveling quickly in the opposite direction of NASA’s LRO (Lunar Reconnaissance Orbiter) when LRO snapped the photo.…
