NASA - National Aeronautics and Space AdministrationMoffett Field, CA – The most advanced system to date for studying fruit flies in space, NASA’s Fruit Fly Lab, is making its debut aboard the International Space Station.

The Fruit Fly Lab-01 mission, planned to launch to the station in December aboard SpaceX’s fifth commercial resupply services (CRS) mission, is the first of a series of fruit fly investigations NASA plans to conduct.

The fruit fly—a widely studied biological research model—plays a lead role in this study and will help us better understand how spaceflight impairs the body’s ability to fight infections.

NASA to investigate Climate change with Airborne Campaigns

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Five new NASA airborne field campaigns, including one managed by NASA’s Jet Propulsion Laboratory, Pasadena, California, will take to the skies starting in 2015 to investigate how long-range air pollution, warming ocean waters and fires in Africa affect our climate.

These studies into several incompletely understood Earth system processes were competitively selected as part of NASA’s Earth Venture-class projects. Each project is funded at a total cost of no more than $30 million over five years. This funding includes initial development, field campaigns and analysis of data.

NASA’s Mars Curiosity Rover confirms first Mineral Mapped from Space

NASA - National Aeronautics and Space AdministrationPasadena, CA – Reddish rock powder from the first hole drilled into a Martian mountain by NASA’s Curiosity rover has yielded the mission’s first confirmation of a mineral mapped from orbit.

“This connects us with the mineral identifications from orbit, which can now help guide our investigations as we climb the slope and test hypotheses derived from the orbital mapping,” said Curiosity Project Scientist John Grotzinger, of the California Institute of Technology in Pasadena.

NASA’S Lunar Reconnaissance Orbiter takes photos of LADEE’s impact crater on the Moon

 

Written by Nancy Neal-Jones
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’S Lunar Reconnaissance Orbiter (LRO) spacecraft has spied a new crater on the lunar surface; one made from the impact of NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) mission.

“The Lunar Reconnaissance Orbiter Camera (LROC) team recently developed a new computer tool to search Narrow Angle Camera (NAC) before and after image pairs for new craters, the LADEE impact event provided a fun test, said Mark Robinson, LROC principal investigator from Arizona State University in Tempe. “As it turns there were several small surface changes found in the predicted area of the impact, the biggest and most distinctive was within 968 feet (295 meters) of the spot estimated by the LADEE operations team. What fun!”

LRO has imaged the LADEE impact site on the eastern rim of Sundman V crater. The image was created by ratioing two images, one taken before the impact and another afterwards. The bright area highlights what has changed between the time of the two images, specifically the impact point and the ejecta. (NASA/Goddard/Arizona State University)

NASA says International Space Station Microgravity Research looks at how to Build Better Bones

 

Written by Jessica Nimon

NASA - National Aeronautics and Space AdministrationHouston, TX – As the saying goes, sticks and stones may break your bones—especially if you have a weak skeleton. This is not only a concern for the elderly who can suffer from osteoporosis. Inactivity from injury, illness, or malnutrition from anorexia or dietary challenges also can lead to bone breakdown in otherwise healthy people.

Another cause of bone loss is living in microgravity. While most people may never experience life in space, the benefits of studying bone loss aboard the International Space Station has the potential to touch all of our lives here on the ground.

Micro-computed tomography bone density imaging shows ground mice (G) with highly connected, dense spongy bone structure, flight mice (F) with less connectivity and flight mice treated with a myostatin inhibitor (F+D) on STS-118 that appear to have bone structure unaffected by microgravity.

NASA’s Soil Moisture Active Passive (SMAP) satellite to help Farmers manage Drought conditions

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – About 60 percent of California is experiencing “exceptional drought,” the U.S. Drought Monitor’s most dire classification. The agency issued the same warning to Texas and the southeastern United States in 2012. California’s last two winters have been among the driest since records began in 1879. Without enough water in the soil, seeds can’t sprout roots, leaves can’t perform photosynthesis, and agriculture can’t be sustained.

Currently, there is no ground- or satellite-based global network monitoring soil moisture at a local level. Farmers, scientists and resource managers can place sensors in the ground, but these only provide spot measurements and are rare across some critical agricultural areas in Africa, Asia and Latin America.

For several months, California has been in a state of "exceptional drought." The state's usually verdant Central Valley produces one-sixth of the U.S.'s crops. (White House via Wikimedia Commons)

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – Inspired by science fiction, three bowling ball-size free-flying Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) have been flying inside the International Space Station since 2006.

These satellites provide a test bed for development and research, each having its own power, propulsion, computer, navigation equipment, and physical and electrical connections for hardware and sensors for various experiments.

NASA to send Fruit Fly Lab to International Space Station

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Fruit flies are bug eyed and spindly, they love rotten bananas, and, following orders from their pin-sized brains, they can lay hundreds of eggs every day.

We have a lot in common.

Genetically speaking, people and fruit flies are surprisingly alike, explains biologist Sharmila Bhattacharya of NASA’s Ames Research Center. “About 77% of known human disease genes have a recognizable match in the genetic code of fruit flies, and 50% of fly protein sequences have mammalian analogues.”

NASA’s Curiosity Rover completes first Martian Year on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Curiosity rover will complete a Martian year — 687 Earth days — on June 24th, having accomplished the mission’s main goal of determining whether Mars once offered environmental conditions favorable for microbial life.

One of Curiosity’s first major findings after landing on the Red Planet in August 2012 was an ancient riverbed at its landing site. Nearby, at an area known as Yellowknife Bay, the mission met its main goal of determining whether the Martian Gale Crater ever was habitable for simple life forms.

NASA's Curiosity Mars rover used the camera at the end of its arm in April and May 2014 to take dozens of component images combined into this self-portrait where the rover drilled into a sandstone target called "Windjana." (NASA/JPL-Caltech/MSSS)
