The SLS rocket is an advanced launch vehicle being built as humanity’s most powerful rocket ever. Within the rocket is the core stage, which will enable SLS to go beyond Earth’s orbit into deep space. The core stage pathfinder pictured here is similar in size, shape and weight to the 212-foot-tall core stage and will be used to test new shipping and handling equipment as well as procedures from the manufacturing site to the test site to the launch site. A pathfinder is built for testing to reduce the risk of damage to actual one-of-a-kind spaceflight hardware for SLS. Credit: NASA/MSFC/MAF/Steven Seipel

Hey there!

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
