Pasadena, CA – Scientists have discovered an unexpected mineral in a rock sample at Gale Crater on Mars, a finding that may alter our understanding of how the planet evolved.
NASA’s Mars Science Laboratory rover, Curiosity, has been exploring sedimentary rocks within Gale Crater since landing in August 2012. In July 2015, on Sol 1060 (the number of Martian days since landing), the rover collected powder drilled from rock at a location named “Buckskin.” Analyzing data from an X-ray diffraction instrument on the rover that identifies minerals, scientists detected significant amounts of a silica mineral called tridymite.

Houston, TX – After 30-days in the confines of a simulated spacecraft, the HERA Mission 10 crew will “splashdown” on the evening of Wednesday, June 1st. HERA—the Human Exploration Research Analog—is one of several analogs used by the Human Research Program (HRP) to research ways to help NASA astronauts move from lower-Earth orbit to deep space explorations.
A spaceflight analog is a situation on Earth that produces physical and mental effects on the body similar to those experienced in space. During the tenth HERA mission, crew members went through all the motions of a real deep space mission without ever actually leaving JSC’s building 220.

Greenbelt, MD – On September 8th, NASA’s OSIRIS-REx spacecraft is scheduled to launch for terra incognita: the unknown surface of the near-Earth asteroid Bennu. Like expeditions of old, OSIRIS-REx’s mission includes mapping the exotic terrain it explores.
Bennu is part of the debris left over from the formation of the solar system and is pristine enough to hold clues to that very early history. OSIRIS-REx – which stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer – will study Bennu in detail and collect a sample to send to Earth for in-depth analysis. The mission also will investigate how pressure from sunlight influences the path of this traveling asteroid.
Daniel Mengden’s Scoreless Innings Streak Ends At 19
Des Moines, IA – The Iowa Cubs rallied in the bottom of the ninth to score two on a walk-off double by Albert Almora to take game four from the Sounds 3-2 at Principal Park Friday night.
J.B. Wendelken came on in the ninth inning to try to preserve a 2-1 lead for the Sounds. Wendelken had the Cubs down to their final out before issuing back-to-back walks to Dan Vogelbach and Taylor Davis.
Arismendy Alcantara came on to pinch run for Vogelbach and advanced to third on an errant throw from Sounds catcher Brian Anderson. With runners on first and third, Almora sent a two-out two-run double to left field and the Cubs took the 3-2 win.

Washington, D.C. – The first human-rated expandable structure that may help inform the design of deep space habitats is set to be installed to the International Space Station Saturday, April 16th. NASA Television coverage of the installation will begin at 5:30am EDT.
The Bigelow Expandable Activity Module (BEAM) will be attached to the station’s Tranquility module over a period of about four hours. Controllers in mission control at NASA’s Johnson Space Center in Houston will remove BEAM from the unpressurized trunk of SpaceX’s Dragon spacecraft, using the robotic Canadarm2, and move it into position next to Tranquility’s aft assembly port.

Fort Knox, KY – The U.S. Army Cadet Command has announced the eight winners of the MacArthur Awards for the school year 2014-2015.
The award recognizes the eight schools, selected from among the 275 senior Army Reserve Officers’ Training Corps (ROTC) units nationwide, as the top programs in the country.
The awards, presented by Cadet Command and the Gen. Douglas MacArthur Foundation, recognize the ideals of “duty, honor and country” as advocated by MacArthur.
NASA study will have 4 People living in an Isolated Habitat for 30 Days in preparation for long Space Missions
NASA’s Johnson Space Center
Houston, TX – 4 people are living in an isolated habitat for 30 days. Why? Science!
This 30 day mission will help our researchers learn how isolation and close quarters affect individual and group behavior. This study at our Johnson Space Center prepares us for long duration space missions, like a trip to an asteroid or even to Mars.
The Human Research Exploration Analog (HERA) that the crew members will be living in is one compact, science-making house.

Pasadena, CA – It was less than an hour into the new day of January 15th, 2006 (EST), when tens of thousands of miles above our planet, two cable cutters and two retention bolts fired, releasing a spring which pushed a 101-pound (46-kilogram) sample return capsule away from its mother ship.
Later, during its final plunge Earthward, the capsule would become the fastest human-made object to enter our atmosphere, achieving a velocity of about 28,600 mph (12.8 kilometers per second).

Pasadena, CA – NASA’s Dawn spacecraft, cruising in its lowest and final orbit at dwarf planet Ceres, has delivered the first images from its best-ever viewpoint. The new images showcase details of the cratered and fractured surface. 3-D versions of two of these views are also available.
Dawn took these images of the southern hemisphere of Ceres on December 10th, at an approximate altitude of 240 miles (385 kilometers), which is its lowest-ever orbital altitude. Dawn will remain at this altitude for the rest of its mission, and indefinitely afterward. The resolution of the new images is about 120 feet (35 meters) per pixel.

Pasadena, CA – In detective stories, as the plot thickens, an unexpected clue often delivers more questions than answers. In this case, the scene is a mountain on Mars. The clue: the chemical compound silica. Lots of silica. The sleuths: a savvy band of Earthbound researchers whose agent on Mars is NASA’s laser-flashing, one-armed mobile laboratory, Curiosity.
NASA’s Curiosity rover has found much higher concentrations of silica at some sites it has investigated in the past seven months than anywhere else it has visited since landing on Mars 40 months ago.
