• Apollo 13, NASA’s third crewed mission to the moon, launched on April 11, 1970. Two days later, on April 13, while the mission was en route to the moon, a fault in the electrical system of one of the Service Module’s oxygen tanks produced an explosion that caused both oxygen tanks to fail and also led to a loss of

  • This image of a circular depression on the surface of Mars was acquired on Jan. 5, 2015 by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter (MRO). The spacecraft has been orbiting Mars since March 2006 and completed its 40,000th orbit around Mars on Feb. 7, 2015. The target of this observation is a circular depression

  • On April 9, 1959, NASA’s first administrator, Dr. Keith Glennan, announced the names of the agency’s first group of astronauts at a news conference in Washington, D.C. Now known as the “Original Seven,” they included three Naval aviators, M. Scott Carpenter, Walter M. Schirra Jr., and Alan B. Shepard Jr.; three Air Force pilots, L. Gordon Cooper Jr., Virgil I.

  • On April 5, 2015, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color image of sea ice off the coast of East Antarctica’s Princess Astrid Coast. White areas close to the continent are sea ice, while white areas in the northeast corner of the image are clouds. One way to better distinguish ice from clouds is

  • As NASA missions explore our solar system and search for new worlds, they are finding water in surprising places. Water is but one piece of our search for habitable planets and life beyond Earth, yet it links many seemingly unrelated worlds in surprising ways. Perhaps the most surprising water worlds are the five icy moons of Jupiter and Saturn that

  • From the International Space Station, NASA astronaut Scott Kelly (stationcdrkelly on Instagram) took this photograph and posted it to social media on April 6, 2015. Kelly wrote, “Australia. You are very beautiful. Thank you for being there to brighten our day. #YearInSpace” Kelly and Russian Federal Space Agency (Roscosmos) cosmonaut Mikhail Kornienko began their one-year mission aboard the space station

  • Leading Edge Asynchronous Propeller Technology (LEAPTech) project researchers at NASA’s Armstrong Flight Research Center are performing ground testing of a 31-foot-span, carbon composite wing section with 18 electric motors. The LEAPTech project will test the premise that tighter propulsion-airframe integration, made possible with electric power, will deliver improved efficiency and safety, as well as environmental and economic benefits. The experimental

  • This view from the Mast Camera (Mastcam) on NASA’s Curiosity Mars rover shows a network of two-tone mineral veins at an area called “Garden City” on lower Mount Sharp.  The veins combine light and dark material. The veins at this site jut to heights of up to about 2.5 inches (6 centimeters) above the surrounding rock, and their widths range

  • Typhoon Maysak strengthened into a super typhoon on March 31, reaching Category 5 hurricane status on the Saffir-Simpson Wind Scale. ESA Astronaut Samantha Cristoforetti captured this image while flying over the weather system on board the International Space Station. The Tropical Rainfall Measuring Mission (TRMM) and Global Precipitation Measurement (GPM) satellites, both co-managed by NASA and the Japan Aerospace Exploration Agency, captured

  • This NASA/ESA Hubble Space Telescope image shows an edge-on view of the spiral galaxy NGC 5023. Due to its orientation we cannot appreciate its spiral arms, but we can admire the elegant profile of its disk. The galaxy lies over 30 million light-years away from us. NGC 5023 is part of the M51 group of galaxies. The brightest galaxy in
