NASA's Goddard Space Flight Center 17 Jul 2019, 07:41 UTC The only visual record of the historic Apollo 11 landing is from a 16mm time-lapse (6 frames per second) movie camera mounted in Buzz Aldrin’s window (right side of Lunar Module Eagle or LM). Due to the small size of the LM windows and the angle at which the movie camera was mounted, what mission commander Neil Armstrong saw as he flew and landed the LM was not recorded. The Lunar Reconnaissance Orbiter Camera (LROC) team reconstructed the last three minutes of the landing trajectory (latitude, longitude, orientation, velocity, altitude) using landmark navigation and altitude call outs from the voice recording. From this trajectory information, and high resolution LROC Narrow Angle Camera (LROC NAC) images and topography, we simulated what Armstrong saw in those final minutes as he guided the LM down to the surface of the Moon. As the video begins, Armstrong could see the aim point was on the rocky northeastern flank of West crater (190 meters diameter), causing him to take manual control and fly horizontally, searching for a safe landing spot. At the time, only Armstrong saw the hazard; he was too busy flying the LM to discuss the situation with mission control.
NASA's Goddard Space Flight Center 16 Jul 2019, 14:00 UTC As a spacecraft descends to the lunar surface, it sprays it with water and other gases that are released as the vehicle thrusts its engines to slow itself for a soft landing. For astronauts who will be cataloging local water supplies, these Earthly contaminants will make it hard to distinguish between bona-fide Moon water and water from their vehicle’s exhaust.

ESA Space Science 16 Jul 2019, 13:00 UTC The first direct measurement of the bar-shaped collection of stars at the centre of our Milky Way galaxy has been made by combining data from ESA’s Gaia mission with complementary observations from ground- and space-based telescopes.

German Aerospace Center (DLR) 15 Jul 2019, 14:55 UTC Ryugu and other asteroids of the common ‘C-class’ consist of more porous material than was previously thought. Small fragments of their material are therefore too fragile to survive entry into the atmosphere in the event of a collision with Earth.
ESA Space Science 15 Jul 2019, 14:00 UTC Gaia is on a mission to survey more than a billion stars, charting the largest three-dimensional map of our galaxy, the Milky Way. In so doing, the spacecraft is revealing the composition, formation and evolution of our galaxy, and a whole lot more.
