Work is progressing on the Bigelow Expandable Activity Module (BEAM), which is scheduled to arrive at the International Space Station (ISS) mid-year 2015 for a two-year technology demonstration.
The BEAM is scheduled to launch aboard a SpaceX cargo resupply mission to the ISS.
Following the arrival of the SpaceX Dragon spacecraft carrying the BEAM to the station, astronauts will use the station’s robotic arm to install the module on the aft port of the Tranquility node.
Built by private space firm, Bigelow Aerospace, the module is to be berthed to the Tranquility node. At that point, the station crew will activate a pressurization system to expand the structure to its full size using air stored within the packed module.
During the two-year test period, station crew members and ground-based engineers will gather performance data on the module, including its structural integrity and leak rate.
An assortment of instruments embedded within module also will provide important insights on its response to the space environment.
This includes radiation and temperature changes compared with traditional aluminum modules.
Back in January 2013, NASA awarded a $17.8 million contract to Bigelow Aerospace to provide the BEAM.
Check out this new and informative video on BEAM, provided by Bigelow Aerospace.

The National Space Biomedical Research Institute (NSBRI) has funded a clinical study to test the Sustained Acoustic Medicine (sam®) device in patients suffering from lower back pain.Thanks to a partnership with the private sector, the idea is to accelerate the development of commercially promising products meeting a medical need in space…as well as on Earth.
Back pain is experienced by astronauts as their spine elongates up to 2 inches while in the microgravity environment of space.
The wearable sam® system enables delivery of one to four hours of therapeutic ultrasound treatment and could be used by astronauts in space.
ZetrOZ, Inc., of Trumbull, CT will receive a Space Medical and Related Technologies Commercialization Program (SMARTCAP) grant. SMARTCAP grants are administered by NSBRI’s Industry Forum.
Ultrasound
Back pain is experienced by astronauts as their spine elongates up to 2 inches while in the microgravity environment of space. sam® was developed for daily use and is prescribed by licensed healthcare practitioners such as orthopedists and physiotherapists for tendonitis and muscle injury recovery.
The wearable sam® system enables delivery of one to four hours of therapeutic ultrasound treatment and could be used by astronauts in space.
“Ultrasound is a great platform for spaceflight, delivering both diagnostic and therapeutic capabilities” said Dr. Dorit Donoviel, NSBRI’s Deputy Chief Scientist and Industry Forum Lead.
Established in 1997 through a NASA competition, NSBRI is headquartered in the Texas Medical Center and is a consortium of leading biomedical institutions.
Sustained acoustic medicine
Donoviel added that ultrasound is portable, wearable and does not deliver harmful radiation. NSBRI has supported the development of diagnostic and therapeutic approaches involving ultrasound for kidney stones, bone, and brain health.
Sustained acoustic medicine holds great promise to accelerate the healing of muscles and tendons as well as possibly bone and cartilage.
“ZetrOZ has developed a disruptive technology and we are excited to fund this important clinical study,” Donoviel stated in an NSBRI press statement.
ZetrOZ, founded in March 2009, is a biomedical ultrasound technology designer and manufacturer.

Welcome home NASA’s International Sun/Earth Explorer-3 (ISEE-3)!
Today, Sunday, August 10th, ISEE-3 is on a trajectory that takes it close to the Moon.
Thanks to an effort led by Keith Cowing of NASAWatch and Dennis Wingo of Skycorp, the ISEE-3 Reboot Project was established. And with a dollar-assist from a crowdsourcing campaign, the creative juices were turned on to full-tap resulting in reestablishing a link to the venerable spacecraft – after more than three decades of space travel.
Now the ISEE-3 Reboot Project team – joined by Goggle – is to transform ISEE-3 into a citizen science project. Data from the spacecraft can be accessed and analyzed by all.
An invite by Cowing to everyone interested in the adventure requests you to join a special Google+ Hangout live event as the ISEE-3 spacecraft makes its long-awaited lunar flyby after 36 years in interplanetary space.
A “Live from ISEE-3 Reboot headquarters” will feature scientists and experts from around the world – all brought together for the historic event.
So tune into the Google Hangout “A Spacecraft for All: The Live ISEE-3 Lunar Flyby.”
The event is slated for Sunday, August 10th, from 10:30 am Pacific Time U.S. to noon PT.

Don’t tell anybody. There may be a secret sauce to cooking in space.
Cornell researchers have taken to the air to better understand the effectiveness of a specially constructed space galley – one designed to be used on the Moon as well as Mars.
Making use of the microgravity-producing “G-Force 1” space simulator plane the team tossed tofu and shredded potatoes into pans of sizzling oil and recorded the resulting oil splatters as the plane climbed and dove in parabolic paths.
Each cycle created a brief period of partial weightlessness, simulating the conditions astronauts would face during extended stays on the Moon’s one-sixth gravity or Mars’ one-third the gravity of Earth.
The work is dedicated to better appreciate cooking 101 on other worlds.
Splatter patterns
A specially constructed space galley was jointly designed by the Cornell team with Susana Carranza of Makel Engineering in Chico, Calif.
The experimenters positioned strips of paper inside the galley fume hood and dyed the oil bright red to help them see and collect splatter patterns. Under reduced gravity conditions, the food settled more slowly into the pan, and more oil appeared to fall outside of it. The oil droplets also traveled a greater distance from the pan than under Earth conditions.That data is being analyzed to measure the particles’ size distribution and distance traveled.
Results will be used to create computer models that could be extrapolated to inform the design of future terrestrial and extraterrestrial cooking technology.
Menu fatigue
“Understanding oil spatter in reduced gravity is a big step toward designing safe and convenient cooking facilities for future space colonies,” said associate professor Jean Hunter in Cornell’s Department of Biological and Environmental Engineering.
Apollo Arquiza and Bryan Caldwell, postdoctoral research associates in the lab, were also key ingredients in devising the research onboard the G-Force 1.
On the flight itself, they were aided by experts at the NASA Reduced Gravity Research Program, including astronaut Cady Coleman and Sarah Gonzales ’96, program coordinator with the Reduced Gravity Education Flight Program.
Incorporating design elements from submarine galleys and chemical fume hoods used in labs, Arquiza and Carranza created an enclosed unit with activated charcoal filters and a fan that sucks in air from the front and draws particles away from the cook.
The team had just 30 seconds to complete each experiment once a parabola began, Arquiza said in a Cornell story authored by Stacy Shackford, a writer for the College of Agriculture and Life Science.
The project is part of a larger investigation by Hunter’s lab into scientific and social aspects of food in space, including a simulated Mars mission in Hawaii to test resource use, menu fatigue and the benefits of home cooking in an enclosed environment, and a bed rest study to test the effects of simulated weightlessness on smell and taste perception.
The European Space Agency’s Rosetta spacecraft has pulled up to comet 67P/Churyumov–Gerasimenko – and what an eye-full!
You might enjoy these comet comments from Chris Lewicki, President and Chief Asteroid Miner at Planetary Resources, Inc.:
What is the difference between a comet and asteroid, after all?
Some comets are believed to be as much as 50% water – dirty snowballs so to speak – and what we’re seeing today at 67P/Churyumov–Gerasimenko is what a comet looks like without all that water vapor in the way.
Comets generally have very eccentric orbits, and spend most of their time in the outer Solar System, having the innards baked out as they make their passages around the sun.
Asteroid orbits are less extreme, so we don’t tend to see their behavior change in time, but it is possible that some asteroids could be extinct comets, waiting for their reserves of ancient water to be discovered.
I’m excited to learn what comet 67P/Churyumov–Gerasimenko has to teach, and there will certainly be surprises.
This mission may help us understand more about the makeup and resources on small Solar System bodies.
