Breaking news on the ISEE-3 mission: It may not be lost – it’s those “O” rings again

High temperatures expanding the seal material could have either impeded the flow, or have precluded the latch valve from opening even with the microswitch indicated to telemetry that the valve was open. — High temperatures expanding the seal material could have either impeded the flow, or have precluded the latch valve from opening even with the microswitch indicated to telemetry that the valve was open.

Huge Meteorite on Mars Discovered by NASA’s Curiosity Rover

This photo by NASA's Curiosity Mars rover shows the huge iron meteorite "Lebanon" (7 feet wide) and its smaller companion "Lebanon B." The two meteorites were found by Curiosity on May 25, 2014. The circular insets are more detailed views by Curiosity's Chem-Cam instrument overlaid on an image by the rover's Remote Micro-Imager.

Cassini spacecraft’s new look at Saturn’s colossal hexagon storm

(Credit: NASA/JPL-Caltech/SSI) — The clear central eye of the storm is about 2000 km across – ten times the typical size on Earth – and clouds at the outer edge of the hurricane on Saturn are moving at more than 500 kph – rather faster than on Earth. (Credit: NASA/JPL-Caltech/SSI)

Large number of dark matter peaks found using gravitational lensing

This map shows the distribution of dark matter (black) in the Universe, overlapping with optical measured clusters of galaxies (red circles). The mass peaks in the map contain significant cosmological information, will provide us with an improved understanding about the dark side of the Universe. The size of this map is about 4 square degrees corresponding to only 2.5% of the full CS82 survey footprint shown in the next figure. (Credit: CS82, SDSS)

Searching for Earth-like planets: Newly spotted frozen world orbits in a binary star system

This artist's rendering shows a newly discovered planet (far right) orbiting one star (right) of a binary star system. The discovery, made by a collaboration of international research teams and led by researchers at The Ohio State University, expands astronomers' notions of where to look for planets in our galaxy.
