NASA - National Aeronautics and Space AdministrationPasadena, 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.

NASA HERA Mission 10 Astronauts to “Splashdown” on June 1st

 

Written by Monica Edwards and Laurie Abadie
NASA’s Human Research Program Engagement & Communications

NASA - National Aeronautics and Space AdministrationHouston, 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.

Astronauts of the HERA 10 crew began their mission on May 2nd. The “splashdown” on June 1st, ending their 30 day analog mission aboard the HERA simulated spacecraft.

NASA’s OSIRIS-REx spacecraft to map asteroid Bennu before collecting sample

 

Written by Elizabeth Zubritsky
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, 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.

The mapping of the near-Earth asteroid Bennu is one of the science goals of NASA’s OSIRIS-REx mission, and an integral part of spacecraft operations. The spacecraft will spend a year surveying Bennu before collecting a sample that will be returned to Earth for analysis. (NASA/Goddard/University of Arizona)

Iowa Cubs steal win from Nashville Sounds with ninth inning rally

 

Daniel Mengden’s Scoreless Innings Streak Ends At 19

Nashville SoundsDes 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.

NASA will connect Bigelow Expandable Activity Module to International Space Station, Saturday

 

Written by Cheryl Warner
NASA’s Headquarters

NASA - National Aeronautics and Space AdministrationWashington, 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.

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

NASA - National Aeronautics and Space AdministrationHouston, 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.

The Human Exploration Research Analog (HERA), formerly known as the Deep Space Habitat, was transferred from the JSC Engineering Directorate to HRP in FY2013. This unique modular three-story habitat was designed and created through a series of university competitions and was previously used in the Desert Research and Technology Studies in the Arizona desert.

NASA’s Stardust Spacecraft sample gave new insights into Comets and our Solar System

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, 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).

The sample return capsule from NASA's Stardust mission successfully landed at the U.S. Air Force's Utah Test and Training Range in Dugway, Utah, at 2:10am Pacific (3:10am Mountain) on January 15, 2006. The capsule carried cometary and interstellar samples gathered by the Stardust spacecraft. (NASA)

Written by Elizabeth Landau / Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, 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.

This image of Ceres was taken in Dawn's low-altitude mapping orbit around a crater chain called Gerber Catena. A 3-D view is also available. (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA)

NASA’s Mars Curiosity Rover discovery of high concentrations of Silica on Mars puzzles Scientists

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, 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.

This May 22, 2015, view from the Mast Camera (Mastcam) in NASA's Curiosity Mars rover shows the "Marias Pass" area where a lower and older geological unit of mudstone -- the pale zone in the center of the image -- lies in contact with an overlying geological unit of sandstone.
