NASA and NOAA satellites — as well as astronauts on the ISS — captured some stunning imagery of Hurricane Ian, as seen from orbit. Our lead image shows an eerie view of the hurricane’s eye on September 28. The Landsat 8 satellite passed directly over Ian’s eye as the storm approached southwest Florida.

We hope this is just as inconsequential as having a piece of toilet paper stuck to your shoe, but images from the Ingenuity helicopter show it had a piece of debris fluttering from its leg during its most recent flight. A blog post from NASA said a small piece of foreign object debris (FOD) was seen in footage from the Mars helicopter’s navigation camera (Navcam) for a portion of its 33rd flight on September 24, 2022.

Astronomers have been assessing a new machine learning algorithm to determine how reliable it is for finding gravitational lenses hidden in images from all sky surveys. This type of AI was used to find about 5,000 potential gravitational lenses, which needed to be confirmed. Using spectroscopy for confirmation, the international team has now determined the technique has a whopping 88% success rate, which means this new tool could be used to find thousands more of these magical quirks of physics.

Here’s a sharper view of Dimorphos, the small asteroid moonlet that the DART (Double Asteroid Redirection Test) spacecraft intentionally crashed into. Eydeet on Imgur created a higher resolution image of Dimorphos by stacking the last few images received from the spacecraft before impact.
First impressions? It’s an egg-shaped rubble pile.

Here’s one of the best videos we’ve seen of the last minutes of the Double Asteroid Redirection Test (DART) mission as it headed towards and slammed into the asteroid Dimorphos. This stabilized version of the last five-and-a-half minutes of images leading up to DART’s intentional collision with the asteroid was produced from NASA’s DART images. It was produced by the YouTube channel Spei’s Space News from Germany.

The first-ever planetary defense technology demonstration mission successfully conducted its mission, slamming into the surface of a distant asteroid and going out in a blaze of glory. NASA’s Double Asteroid Redirection Test (DART) spacecraft acted as a kinetic impactor, colliding with the small and harmless asteroid Dimorphos on September 26 at 7:14PM ET, with the hope of deflecting it.

Have you ever attended a star party, where amateur astronomers set up telescopes and invite the public to take a look at the night sky? If so, then you understand and appreciate how much these part-time but incredibly enthusiastic stargazers love to share the wonders of our Universe with others.
That type of passion and generosity of heart is the basis of a new organization that hopes to harness the proven capability of astronomy to bring hope, wonder and science to marginalized and isolated students and communities around the world.
Astronomy For Equity (A4E) looks to bring together existing resources within communities in war-torn or developing countries, and provide the tools and resources to support experienced volunteers and teachers for public education programs that are already in place. Their first initiative will help get telescopes to astronomy students in Libya.

For the first time, a spacecraft has detected acoustic and seismic waves from impacts on Mars. NASA’s InSight lander made the detections from four meteoroids that crashed on Mars in 2020 and 2021. Ever since the mission landed on the Red Planet in 2018, scientists have been hoping to be able to detect impacts with InSight’s seismometer, which was mainly designed to sense Marsquakes. But these impacts are the first the lander has detected.

In April of this year, the first all-private astronaut mission to the International Space Station was successfully conducted when Axiom Space sent four non-NASA astronauts to space during the 17-day Axiom-1 Mission (Ax-1). Based on the endeavor’s success, NASA and Axiom Space have signed an agreement for the second such mission to the ISS, which will take place in the second quarter of 2023.

Scientists with NASA’s Perseverance Mars rover said today that the rover has collected several “tantalizing” organic rock samples from an ancient river delta on the Red Planet. These samples have now been stowed for a planned future mission that hopes to retrieve the specimens and bring them back to Earth for the first-ever sample return from Mars.
