A new mission, the Neutron Star Interior Composition Explorer (NICER), is headed for the International Space Station (@iss) next month to observe one of the strangest observable objects in the universe.

Launching aboard SpaceX's CRS-11 commercial resupply mission, NICER will be installed aboard the orbiting laboratory as the first mission dedicated to studying neutron stars, a type of collapsed star that is so dense scientists are unsure how matter behaves deep inside it. In this photo, NICER’s X-ray concentrator optics are inspected under a black light for dust and foreign object debris that could impair functionality once in space. The payload’s 56 mirror assemblies concentrate X-rays onto silicon detectors to gather data that will probe the interior makeup of neutron stars, including those that appear to flash regularly, called pulsars.

Observing images of craters on Mars provides scientists insight into the water that carved them and the Red Planet's history of water activity.

What do you think this tadpole-shaped impact crater says about the water that used to fill it? Based on the terrain-height information and knowing that water always flows downhill, scientists were able to infer that the water in the tadpole crater was flowing down, and outward. The image was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on our Mars Reconnaissance Orbiter. Image credit: NASA/JPL-Caltech/Univ. of Arizona #nasa #space mars
