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.2 -

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, 2017.2 -

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.

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.

NASA's Hubble Spots Embryonic Galaxy SPT0615-JD Download
This Hubble Space Telescope image shows the farthest galaxy yet seen in an image that has been stretched and amplified by a phenomenon called gravitational lensing.
The embryonic galaxy, named SPT0615-JD, existed when the universe was just 500 million years old. Though a few other primitive galaxies have been seen at this early epoch, they have essentially all looked like red dots, given their small size and tremendous distances.
However, in this case, the gravitational field of a massive foreground galaxy cluster, called SPT-CL J0615-5746, not only amplified the light from the background galaxy but also smeared the image of it into an arc (about 2 arcseconds long).
Image analysis shows that the galaxy weighs in at no more than 3 billion solar masses (roughly 1/100th the mass of our fully grown Milky Way galaxy). It is less than 2,500 light-years across, half the size of the Small Magellanic Cloud, a satellite galaxy of our Milky Way.
The object is considered prototypical of young galaxies that emerged during the epoch shortly after the big bang.2 -

A composite of three consecutive exposures, this night skyscape follows the January 7 launch and first stage landing of a Falcon 9 rocket from a beach on planet Earth's space coast.
With the launch from Cape Canaveral Air Force Station, the bright streak beginning farthest left traces the initial phase of the rocket's flight.
A visible upward hook marks the first stage beginning its return trajectory with a "boostback burn" near the top of the arc, while the second stage separates and continues toward orbit.
Above the top of the launch arc due to perspective, a bright streak shows the returning first stage slowing and descending toward the Cape.
Centered below, the streak at the horizon is a 17 second burn finally slowing the first stage to a successful vertical landing about 8 minutes after launch at Landing Zone 1.
During the scene's effective long exposure time, the background stars leave short trails in the night sky of the rotating planet.2 -

The combination of morphological and topographic information from stereo images from NASA's Mars Reconnaissance Orbiter, as well as compositional data from near-infrared spectroscopy has been proven to be a powerful tool for understanding the geology of Mars.
Beginning with the OMEGA instrument on the European Space Agency's Mars Express orbiter in 2003, the surface of Mars has been examined at near-infrared wavelengths by imaging spectrometers that are capable of detecting specific minerals and mapping their spatial extent. The CRISM (Compact Reconnaissance Imaging Spectrometer for Mars) instrument on our orbiter is a visible/near-infrared imaging spectrometer, and the HiRISE camera works together with it to document the appearance of mineral deposits detected by this orbital prospecting.
Mawrth Vallis is one of the regions on Mars that has attracted much attention because of the nature and diversity of the minerals identified by these spectrometers. It is a large, ancient outflow channel on the margin of the Southern highlands and Northern lowlands. Both the OMEGA and CRISM instruments have detected clay minerals here that must have been deposited in a water-rich environment, probably more than 4 billion years ago.
For this reason, Mawrth Vallis is one of the two candidate landing sites for the future Mars Express Rover Mission planned by the European Space Agency. This image was targeted on a location where the CRISM instrument detected a specific mineral called alunite, KAl3(SO4)2(OH)6. Alunite is a hydrated aluminum potassium sulfate, a mineral that is notable because it must have been deposited in a wet acidic environment, rich in sulfuric acid.
Our image shows that the deposit is bright and colorful, and extensively fractured. The width of the cutout is 1.2 kilometers.

In this view, individual layers of haze can be distinguished in the upper atmosphere of Titan, Saturn's largest moon.
Titan's atmosphere features a rich and complex chemistry originating from methane and nitrogen and evolving into complex molecules, eventually forming the smog that surrounds the moon.
This natural color image was taken in visible light with the Cassini spacecraft wide-angle camera on March 31, 2005, at a distance of approximately 20,556 miles (33,083 kilometers) from Titan.
The view looks toward the north polar region on the moon's night side. Part of Titan's sunlit crescent is visible at right. The Cassini spacecraft ended its mission on Sept. 15, 2017.
