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

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 Stardust spacecraft may have discovered first samples of Interstellar Dust

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Seven rare, microscopic interstellar dust particles that date to the beginnings of the solar system are among the samples collected by scientists who have been studying the payload from NASA’s Stardust spacecraft since its return to Earth in 2006.

If confirmed, these particles would be the first samples of contemporary interstellar dust.

A team of scientists has been combing through the spacecraft’s aerogel and aluminum foil dust collectors since Stardust returned in 2006.

The largest interstellar dust track found in the Stardust aerogel collectors was this 35 micron-long hole produced by a 3 picogram mote that was probably traveling so fast that it vaporized upon impact. The other two likely interstellar dust grains were traveling more slowly and remained intact after a soft landing in the aerogel. (Andrew Westphal, UC Berkeley)

NASA tests Free-Flying SPHERES in hopes they can perform Housekeeping jobs for Astronauts

 

Written by Maria Alberty
NASA’s Ames Research Center

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.

Three satellites fly in formation as part of the Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) investigation. This image was taken during Expedition 14 in the Destiny laboratory module. (NASA)

NASA’s Johnson Space Center has Astronauts Test Tools Underwater for Asteroid Mission

 

NASA’s Johnson Space Center

NASA - National Aeronautics and Space AdministrationHouston, TX – NASA is planning to send astronauts to an asteroid in the 2020s, and preparations are already being made.

Stan Love and Steve Bowen have between them spent more than 62 hours in the vacuum of space on nine shuttle mission spacewalks, and they’re putting that experience to use here on Earth by helping engineers determine what astronauts will need on NASA’s next step toward Deep Space.

Steve Bowen is lowered into the Neutral Buoyancy Laboratory at Johnson Space Center to test spacewalk suits and tools for a mission to an asteroid. (NASA)

NASA says International Space Station experiment “Spiders in Space” inspires Children, Spider Man Fans

 

Written by Laura Niles

NASA - National Aeronautics and Space AdministrationHouston, TX – While spiders were busy spinning webs in space, researchers on Earth weaved their knowledge of this activity into educational materials to inspire and motivate students.

Now, this free, Web-based guide is being re-released through Scholastic and Sony Pictures as curriculum for educators to leap on the excitement surrounding the release of the film, “The Amazing Spider-Man 2.”

For those who may have missed it, this guide’s inspiration came from real science using spiders in space.

And although the spiders were exposed to microgravity and radiation in space, they did not morph into mutants; rather, they adapted quite well and provided a biology lesson learned around the world.

NASA announces Video to be Beamed by Laser back to Earth from International Space Station

 

Written by David Israel and Mark Whalen
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A team of about 20 working at NASA’s Jet Propulsion Laboratory in Pasadena, CA, through the lab’s Phaeton early-career-hire program, led the development of the Optical Payload for Lasercomm Science (OPALS) investigation, which is preparing for an April 14th launch to the International Space Station aboard the SpaceX-3 mission.

The goal? NASA’s first optical communication experiment on the orbital laboratory.

This artist's concept shows how the Optical Payload for Lasercomm Science (OPALS) laser will beam data to Earth from the International Space Station. (NASA)

NASA to conduct long term space flight experiment on Twins

 

Written by Dr. Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Consider a pair of brothers, identical twins. One gets a job as an astronaut and rockets into space. The other gets a job as an astronaut, too, but on this occasion he decides to stay home. After a year in space, the traveling twin returns home and they reunite.

Are the identical twins still … identical?

NASA is about to find out.

NASA - National Aeronautics and Space AdministrationPasadena, CA – A team of scientists at NASA’s Johnson Space Center in Houston and the Jet Propulsion Laboratory in Pasadena, CA, has found evidence of past water movement throughout a Martian meteorite, reviving debate in the scientific community over life on Mars.

In 1996, a group of scientists at Johnson led by David McKay, Everett Gibson and Kathie Thomas-Keprta published an article in Science announcing the discovery of biogenic evidence in the Allan Hills 84001(ALH84001) meteorite.

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – For the first time in more than a decade, five NASA Earth science missions will be launched into space in the same year, opening new and improved remote eyes to monitor our changing planet.

The five launches, including two to the International Space Station (ISS), are part of an active year for NASA Earth science researchers, who also will conduct airborne campaigns to the poles and hurricanes, develop advanced sensor technologies, and use satellite data and analytical tools to improve natural hazard and climate change preparedness.
