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.

Houston, TX – Astronomers using the TRAPPIST telescope at ESO’s La Silla Observatory have discovered three planets with sizes and temperatures similar to those of Venus and Earth, orbiting an ultra-cool dwarf star just 40 light-years from Earth.
Michaël Gillon of the University of Liège in Belgium, leading a team of astronomers including Susan M. Lederer of NASA Johnson Space Center, have used the TRAPPIST telescope to observe the star 2MASS J23062928-0502285, now also known as TRAPPIST-1.
They found that this dim and cool star faded slightly at regular intervals, indicating that several objects were passing between the star and the Earth.

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.
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 – 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.

Houston, TX – NASA’s commercial partner Orbital ATK plans to launch its Cygnus spacecraft into orbit December 3rd, atop a United Launch Alliance Atlas V rocket for its fourth contracted resupply mission.
The flight, known as CRS-4, will deliver samples and equipment to the International Space Station for research investigations that will occur during current and future expeditions in the many science disciplines aboard the orbiting multi-disciplinary laboratory.
This delivery will support significant research being conducted off the Earth to benefit the Earth, including investigations in advanced and automated data collection and in the behavior of gases, liquids and burning textiles in microgravity.

Pasadena, CA – A piece of tape can only be used a few times before the adhesion wears off and it can no longer hold two surfaces together. But researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California, are working on the ultimate system of stickiness, inspired by geckos.
Thanks to tiny hairs on the bottom of geckos’ feet, these lizards can cling to walls with ease, and their stickiness doesn’t wear off with repeated usage. JPL engineer Aaron Parness and colleagues used that concept to create a material with synthetic hairs that are much thinner than a human hair. When a force is applied to make the tiny hairs bend, that makes the material stick to a desired surface.

Kennedy Space Center, FL – Fresh food grown in the microgravity environment of space officially is on the menu for the first time for NASA astronauts on the International Space Station. Expedition 44 crew members, including NASA’s one-year astronaut Scott Kelly, are ready to sample the fruits of their labor after harvesting a crop of “Outredgeous” red romaine lettuce Monday, August 10th, from the Veggie plant growth system on the nation’s orbiting laboratory.
The astronauts will clean the leafy greens with citric acid-based, food safe sanitizing wipes before consuming them. They will eat half of the space bounty, setting aside the other half to be packaged and frozen on the station until it can be returned to Earth for scientific analysis.

Pasadena, CA – NASA’s Mars Odyssey spacecraft will reach a major milestone June 23rd, when it completes its 60,000th orbit since arriving at the Red Planet in 2001.
Named after the bestselling novel “2001: A Space Odyssey” by Arthur C. Clarke, Odyssey began orbiting Mars almost 14 years ago, on October 23rd, 2001. On December 15th, 2010, it became the longest-operating spacecraft ever sent to Mars, and continues to hold that record today.
Odyssey, which discovered widespread water ice just beneath the surface of the Red Planet, is still going strong today, serving as a key communications relay for NASA’s Mars rovers and making continued contributions to planetary science.
