The success of the Mars Ingenuity helicopter has encouraged engineers to consider and reconsider all options for remote aerial observations of the Red Planet. Additional methods for birds-eye views of Mars would not only provide higher resolution data on the landscapes where rovers can’t go — such as canyons and volcanoes — but also could include studying atmospheric and climate processes that current orbiters and rovers aren’t outfitted to observe.

Northrup Grumman’s Cygnus cargo spacecraft conducted a successful reboost of the International Space Station over the past weekend, on Saturday, June 25, 2022. The Cygnus NG-17 “Piers Sellers” is the first US-based spacecraft to provide a substantial orbital adjustment to the ISS since the space shuttles retired in 2011. Russia’s Progress cargo spacecraft has been the primary source for station reboosts, attitude control, and debris avoidance maneuvers.
“This reboost of the ISS using Cygnus adds a critical capability to help maintain and support the space station,” said Steve Krein, vice president, civil and commercial space, tactical space systems, Northrop Grumman, in a press release. “It also demonstrates the enormous capability Cygnus offers the ISS and future space exploration efforts.”

Astronomers using the ALMA Observatory have discovered an unusual, massive star near the center of our galaxy, a star that has two spiral arms. The arms are part of an accretion disk, a broad disk of dust and gas surrounding the protostar. While this is not the first star to be seen with such rare arm-like features, researchers say they believe they can track the formation of the spiral arms to a close encounter the star had with another object.

A microwave oven–sized cubesat launched to space today from New Zealand by commercial company Rocket Lab and their Electron rocket. The small satellite will conduct tests to make sure the unique lunar orbit for NASA’s future Lunar Gateway is actually stable.
The Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, or CAPSTONE, mission launched at 5:55 a.m. EDT (09:55 UTC) on Tuesday June 28 from the Rocket Lab Launch Complex 1 on the Mahia Peninsula of New Zealand. The Electron has now flown 27 times with 24 successes and 3 failures.

A newly discovered supercluster of galaxies is so distant that astronomers say its light has been traveling for over twelve billion years to reach telescopes on Earth. But this cluster, named SPT2349 ?56 is gigantic, and so old that it is actually classified as a proto-cluster of galaxies, meaning it might be one of the earliest large clusters of galaxies in our Universe. It is also one of the most actively star-forming proto-clusters known.

ESA and NASA dusted off some old data from four retired space telescopes and combined forces to reveal new images of the four galaxies that our closest to our own Milky Way galaxy. One thing is common among the four new images: they are full of dust!

From orbit, this landscape on Mars looks like a lacy honeycomb or a spider web. But the unusual polygon-shaped features aren’t created by Martian bees or spiders; they are actually formed from a ongoing process of seasonal change from created from water ice and carbon dioxide.

For nearly 30 years Geoff Notkin has traveled the world in search of meteorites, those ancient relics from outer space that have fallen to Earth. He shared his adventures on the Science Channel series “Meteorite Men,” and through lectures and appearances across almost every continent, he has sparked interest in space science and exploration. He has been a devoted meteorite hunter and collector, amassing a large collection. But now, after much deliberation, Notkin has decided to auction off some of his personal meteorite collection, as well as other personal items.
Of course, our first question was, why? Is he leaving the field of meteorite hunting?

Comets that venture close to the Sun can transform into something beautiful, but sometimes they encounter incineration if they get too close. Of the various types of comets that orbit close to the Sun, astronomers had never seen the destruction of the type classified as “near-Sun” comets. But thanks to a variety of telescopes on summit of Mauna Kea in Hawai?i, scientists have now captured images of a periodic rocky near-Sun comet breaking apart. They say the disintegration of this comet could help explain the scarcity of such periodic near-Sun comets.

Have you ever seen wispy arcs and rings in astronomical images taken by the Hubble Space Telescope and other observatories? These unusual features are caused by a quirk of nature called gravitational lensing, which occurs when light from a distant object is distorted by a closer massive object along the same line of sight. This distortion effectively creates a giant lens which magnifies the background light source, allowing astronomers to observe objects embedded within those lens-created arcs and rings that are otherwise be too far and too dim to see.
A group of researchers are working on plans to build a spacecraft that could apply this quirk by using our Sun as a gravitational lens. Their goal is to see distant exoplanets orbiting other stars, and to image an Earth-like exoplanet, seeing it in exquisite detail, at a resolution even better than the well-known Apollo 8 Earthrise photo.
