Color View Dodo and Baby Bear Trenches
This feature looks a bit like a bear's face. What is it really? There's a hill with a V-shaped collapse structure (the nose), two craters (the eyes), and a circular fracture pattern (the head). The circular fracture pattern might be due to the settling of a deposit over a buried impact crater. Maybe the nose is a volcanic or mud vent and the deposit could be lava or mud flows? Maybe just grin and bear it. https://photojournal.jpl.nasa.gov/catalog/PIA25709
Polar bears already face shorter ice seasons - limiting prime hunting and breeding opportunities. Nineteen separate polar bear subpopulations live throughout the Arctic, spending their winters and springs roaming on sea ice and hunting. The bears have evolved mainly to eat seals, which provide necessary fats and nutrients in the harsh Arctic environment. Polar bears can't outswim their prey, so instead they perch on the ice as a platform and ambush seals at breathing holes or break through the ice to access their dens. The total number of ice-covered days declined at the rate of seven to 19 days per decade between 1979 and 2014. The decline was even greater in the Barents Sea and the Arctic basin. Sea ice concentration during the summer months — an important measure because summertime is when some subpopulations are forced to fast on land — also declined in all regions, by 1 percent to 9 percent per decade.

Work began on March 11, 2010 to replace a set of elevation bearings on the giant Mars antenna at NASA Deep Space Network complex in Goldstone, Calif.
The giant Mars antenna at NASA Deep Space Network Goldstone Deep Space Communications Complex replaced four elevation bearings as part of a major refurbishment.
Technology derived by NASA for monitoring control gyros in the Skylab program is directly applicable to the problems of fault detection of railroad wheel bearings. Marhsall Space Flight Center's scientists have developed a detection concept based on the fact that bearing defects excite resonant frequency of rolling elements of the bearing as they impact the defect. By detecting resonant frequency and subsequently analyzing the character of this signal, bearing defects may be detected and identified as to source.

Many of the depressions in Noctis Labyrinthus contain water-bearing minerals, suggesting that water was available and persistent in this region during the Late Hesperian to Amazonian epochs on Mars, as seen by NASA Mars Reconnaissance Orbiter.

The Mast Camera (Mastcam) on NASA's Curiosity Mars rover captured this mosaic as it explored the "clay-bearing unit" on Feb. 3, 2019 (Sol 2309). This landscape includes the rocky landmark nicknamed "Knockfarril Hill" (center right) and the edge of Vera Rubin Ridge, which runs along the top of the scene. Made of many individual images, this mosaic includes a variety of geological features, such as several kinds of bedrock and sand. The clay-bearing unit has been an important scientific destination since before Curiosity launched. NASA's Mars Reconnaissance Orbiter (MRO) spied a strong clay "signal" in this region, indicating that water may have played a role in its formation. On its long trek since landing in 2012, Curiosity has discovered many examples of mudstones containing clay minerals. The scene is presented with a color adjustment that approximates white balancing to resemble how the rocks and sand would appear under daytime lighting conditions on Earth. https://photojournal.jpl.nasa.gov/catalog/PIA23139
NASA's Curiosity Mars rover captured this view of a sulfate-bearing region ahead of its current location. Dark boulders near the center of the panorama are thought to have formed from sand deposited in ancient streams or ponds. Scattered gray rocks covering the hillside on the right are all that remain of a sandstone capping unit that once covered this area. This panorama is made up of 10 individual images that were captured by Curiosity's Mast Camera, or Mastcam, on May 2, 2022, the 3,462nd Martian day, or sol, of the mission. The images were stitched together after they were sent back to Earth. Behind the dark boulders – in the middle of the image – is a mountain that makes up part of the sulfate-bearing region; layers within this region can be seen as stripes across the mountainside. These layers represent an excellent record of how Mars' water and climate changed over time. https://photojournal.jpl.nasa.gov/catalog/PIA25367
Stitched together from 116 images, this view captured by NASA's Curiosity Mars rover shows the path it will take in the summer of 2020 as it drives to the "sulfate-bearing unit," the next layer it will be investigating on the 3-mile-tall (5-kilometer-tall) Mount Sharp. Curiosity has to drive around a large sand patch in order to reach a place where it can ascend to the sulfate-rich region. The upper part of the mountain looms at the top image. The images were taken by the rover's Mast Camera, or Mastcam, on Jan. 10, 2020, the 2,641st Martian day, or sol, of the mission. The panorama has been white-balanced so that the colors of the rock materials resemble how they would appear under daytime lighting conditions on Earth. https://photojournal.jpl.nasa.gov/catalog/PIA23973
iss073e0917376 (Oct. 20, 2025) --- Tiny ball bearings surround a larger central bearing during the Fluid Particles experiment, conducted inside the Microgravity Science Glovebox (MSG) aboard the International Space Station’s Destiny laboratory module. A bulk container installed in the MSG, filled with viscous fluid and embedded particles, is subjected to oscillating frequencies to observe how the particles cluster and form larger structures in microgravity. Insights from this research may advance fire suppression, lunar dust mitigation, and plant growth in space. On Earth, the findings could inform our understanding of pollen dispersion, algae blooms, plastic pollution, and sea salt transport during storms.

CAPE CANAVERAL, Fla. – Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, the B and D truck sections of crawler-transporter 2, or CT-2, are being raised up to prepare for installation of new roller bearing assemblies. Sections of the crawler’s large metal tracks have been removed. Work continues in high bay 2 to upgrade CT-2. The modifications are designed to ensure CT-2’s ability to transport launch vehicles currently in development, such as the agency’s Space Launch System, to the launch pad. The Ground Systems Development and Operations Program office at Kennedy is overseeing the upgrades. For more than 45 years the crawler-transporters were used to transport the mobile launcher platform and the Apollo-Saturn V rockets and, later, space shuttles to Launch Pads 39A and B.

The pair was developing techniques by which the non-SAFER equipped spacewalker will impart a rotation to the SAFER-using spacewalker during the STS-64 mission. Once the SAFER astronaut is spinning, the device will be activated and its automatic attitude hold capability will be tested. SAFER is to fly on STS-76 as well.

KENNEDY SPACE CENTER, FLA. -- Technicians give the signal for a crane to begin lifting a jacking, equalization and leveling (JEL) cylinder and bearing on Crawler-Transporter No. 2. During routine maintenance inspections last week, technicians removed two of the 16 JEL cylinders on the crawler to gain access to the bearings and found three of the four bearings cracked. Further eddy current inspections indicated that cracks are present on 15 of the bearings. There are 16 cylinders and 32 bearings per crawler. Engineers are evaluating the situation to determine the cause of the cracks and an appropriate solution to the problem.
