Seeing an X-Plane's Sonic Boom



This schlieren image shows an Air Force Test Pilot School T-38 in a transonic state, meaning the aircraft is transitioning from a subsonic speed to supersonic.

Pluto Global Color Map



This new, detailed global mosaic color map of Pluto is based on a series of three color filter images obtained by the Ralph/Multispectral Visual Imaging Camera aboard New Horizons during the NASA spacecraft’s close flyby of Pluto in July 2015.

Bit outside of space, but reminds me of all the regenerative scenes in space movies. good article on hydrogel advancements. This pairs with new 3D printing (3DEAL) technologies that can use hydrogels fabricate complex biological environments such as tissues or even organs. this would be very good for drug testing environments.

Investigating Mars: Rabe Crater



The majority of the dune field in Rabe Crater consists of a sand sheet with dune forms on the surface. The sand sheet is where a thick layer of sand has been concentrated. As continued winds blow across the sand surface it creates dune forms.

The depth of the sand sheet prevents excavation to the crater floor and the dune forms all appear connected. Rabe Crater is 108 km (67 miles) across. Craters of similar size often have flat floors.

Rabe Crater has some areas of flat floor, but also has a large complex pit occupying a substantial part of the floor. The interior fill of the crater is thought to be layered sediments created by wind and or water action. The pit is eroded into this material. The eroded materials appear to have stayed within the crater forming a large sand sheet with surface dune forms as well as individual dunes where the crater floor is visible. The dunes also appear to be moving from the upper floor level into the pit.

The Odyssey spacecraft has spent over 15 years in orbit around Mars, circling the planet more than 69000 times. It holds the record for longest working spacecraft at Mars. THEMIS, the IR/VIS camera system, has collected data for the entire mission and provides images covering all seasons and lighting conditions.

Over the years many features of interest have received repeated imaging, building up a suite of images covering the entire feature. From the deepest chasma to the tallest volcano, individual dunes inside craters and dune fields that encircle the north pole, channels carved by water and lava, and a variety of other feature, THEMIS has imaged them all.

Hubble's Holiday Nebula “Ornament”



The Hubble Space Telescope captured what looks like a colorful holiday ornament in space. It's actually an image of NGC 6326, a planetary nebula with glowing wisps of outpouring gas.

Apollo Landing Sites



With four of the six planned lunar missions completed, this chart has been prepared to show the various areas of the lunar "nearside" to be visited by astronauts representing the NASA Apollo program.

Apollo's 11, 12, 14 and 15 are shown at their respective landing points. Apollo 16 and Apollo 17, planned for later this year at Descartes and Taurus Littrow, respectively, also are depicted on the map.

Apollo 11 - TV Transmission



(19 July 1969) - A near vertical view of Diamondback Rille is seen in this television transmission from the Apollo 11 spacecraft, during its second revolution of the moon. The center of the picture is located at about 26.9 degrees east longitude and 1.2 degrees north latitude. This area is just east of the Apollo Landing Site 2. The crew of the Apollo 11 lunar landing mission is astronauts Neil A. Armstrong, commander; Michael Collins, command module pilot; and Edwin E. Aldrin Jr., lunar module pilot.

Rhea



This image is from Cassini's final observation of Saturn's icy moon Rhea (949 miles or 1,527 kilometers across) on May 2, 2017.

The spacecraft was at the time high above the plane of Saturn's rings, looking down at Rhea's northern hemisphere. The northern rim of the giant Tirawa impact basin can be seen along the limb at left.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera at a distance of approximately 230,000 miles (370,000 kilometers) from Rhea.

The Cassini spacecraft ended its mission on Sept. 15, 2017.

Saturn's rings, made of countless icy particles, form a translucent veil in this view from NASA's Cassini spacecraft. Saturn's tiny moon Pan, about 17 miles (28 kilometers) across, orbits within the Encke Gap in the A ring.

Beyond, we can see the arc of Saturn itself, its cloud tops streaked with dark shadows cast by the rings.

This image was taken in visible light with the Cassini spacecraft narrow-angle camera on Feb. 12, 2016, at a distance of approximately 746,000 miles (1.2 million kilometers) from Pan.

The Cassini spacecraft ended its mission on Sept. 15, 2017.

Snoopy is NASA's official safety mascot. Every astronaut since 1968 has worn a silver Snoopy pin into space; upon return, the astronauts present the pin as a special recognition to a civilian team member who helped keep them safe.

Oddly enough, an elongated coronal hole (the darker area near the center) seems to shape itself into a single, recognizable question mark over the period of one day (Dec. 21-22, 2017).

Coronal holes are areas of open magnetic field that appear darker in extreme ultraviolet light, as is seen here. These holes are the source of streaming plasma that we call solar wind.

While this exercise is akin to seeing shapes in clouds, it is fun to consider what the sun might be asking.

Plenty of other video out there too. I didn't manage to shot anything but I know tons of people caught it.
