Video: The effects of weightlessness on vision

Here’s a new video in a NASA series about research on the Int. Space Station. This entry focuses, so to speak, on the effects of weightlessness on human vision:

From the caption:

Every month on StationLIFE, we’ll focus on a scientific area where the International Space Station is conducting groundbreaking research. This month, astronaut Tracy Dyson talks about a unique challenge to humans flying in space: vision impairment.

Even after 50 years of human spaceflight, we are still exploring the effects microgravity can have on human health. In recent years, a new trend was identified: some International Space Station astronauts reported vision degradation during spaceflight. Research has identified a possible link between vision impairment and the increased intracranial pressure caused by shifts in bodily fluids from the lower extremities to the upper part of the body in microgravity. This is an area of intense interest aboard ISS, with implications for future exploration missions.

There is also an Earth benefit to the vision research aboard the space station; these studies provide insight into structural changes that can occur in the eyes and nervous system, which could be relevant for patients suffering from a wide range of ocular diseases such as glaucoma. It also provides data that could be used to help patients suffering from brain diseases, such as hydrocephalus and high blood pressure in the brain. 

Video: A cup of coffee in micro-g

I’ve had a posts here and here recently about the Zero Gravity Cocktail Glass from Cosmic Lifestyle. Here is an interesting NASA video with Dr. Mark Weislogel of Portland State University about the development of these types of beverage holders, as well as pipes and other fluid flow hardware, that use capillary forces to provide easier and more practical use in weightlessness:

NASA Commentator Brandi Dean talks with Dr. Mark Weislogel of Portland State University about a new experiment on the International Space Station to test a drinking cup that will work in weightlessness. The Capillary Beverage experiment applies recent findings about capillary flows and surface tension and their impact on fluids in microgravity to design containers that mimic the role of gravity and should provide station crew members with the ability to actually drink water or coffee or other beverages rather than sucking them out of beverage bags with straws, as they do now.

Opportunity for school districts to participate in ISS student experiment program

An announcement from the Student Spaceflight Experiments Program (SSEP):

New Flight Opportunity for School Districts:
Announcing Student Spaceflight Experiments Program (SSEP) Mission 9
to the International Space Station for 2015-16 Academic Year

Student Spaceflight Experiments Program (SSEP) Mission 9
to the International Space Station

Opportunity for Schools to Engage Grade 5-16 Students in the ”
Design of Microgravity Experiments for Flight to the International Space Station

STEM Project-Based Learning Through Immersion in an Authentic Research Experience

Time Critical: interested schools are directed to inquire about the program no later than April 30, 2015

March 20, 2015: Washington, D.C. – The National Center for Earth and Space Science Education (NCESSE), and the Arthur C. Clarke Institute for Space Education, in partnership with NanoRacks LLC, announce a new opportunity for school districts across the U.S., Canada, and internationally to participate in the eleventh flight opportunity of the Student Spaceflight Experiments Program (SSEP).

Launched in June 2010, SSEP was designed as a model U.S. National STEM (Science, Technology, Engineering, and Math) education program that immerses typically 300 students across a community in every facet of authentic scientific research of their own design, using a highly captivating spaceflight opportunity on the International Space Station (ISS).

The program is designed to inspire and engage the next generation of scientists and engineers, and is accomplished by providing each participating community their own very real Space Program.

SSEP Mission 9 to ISS will provide each participating community a real research mini-laboratory capable of supporting a single microgravity experiment, and all launch services to fly the mini-lab to ISS in Spring 2016, and return it safely to Earth for harvesting and analysis. Mirroring how professional research is done, student teams across the community submit research proposals, and go through a formal proposal review process to select the flight experiment. The design competition – from program start, to experiment design, to submission of proposals by student teams – spans 9 weeks from September 7 to November 6, 2015. A curriculum and content resources for teachers and students support foundational instruction on science conducted in microgravity (in a weightless environment) and experiment design. Additional SSEP program elements leverage the experience to engage the entire community, embracing a Learning Community Model for STEM education.

SSEP provides seamless integration across STEM disciplines through an authentic, high visibility research experience—an approach that embraces the Next Generation Science Standards. For school districts—even individual schools—SSEP provides an opportunity to implement a systemic, high caliber STEM education program tailored to community need. More broadly, SSEP is about a commitment to student ownership in exploration, to science as journey, and to the joys of learning.

SSEP is open to U.S. schools and school districts serving grade 5 through 12 students, 2- and 4-year colleges and universities, informal science education organizations, and internationally through the Center’s Arthur C. Clarke Institute for Space Education. SSEP is not designed for an individual class or a small number of students in a community.

Student teams are able to design experiments across diverse fields, including: seed germination, crystal growth, physiology and life cycles of microorganisms, cell biology and growth, food studies, and studies of micro-aquatic life. Experiments require design to the technology and engineering constraints imposed by the mini-laboratory, and flight operations to and from low Earth orbit.

“SSEP is designed to empower the student as scientist, and within the real-world context of science. Student teams design a real experiment, propose for a real flight opportunity, experience a formal proposal review, and go through a NASA flight safety review. They even have their own science conference at the Smithsonian National Air and Space Museum, where they are immersed in their own community of researchers”, said Dr. Jeff Goldstein, creator of SSEP and NCESSE Center Director. “SSEP is about introducing real science to our children and if you give them a chance to be scientists, stand back and be amazed.”

SSEP Mission 9 to ISS includes an experiment design competition September 7 through November 6, 2015. Flight experiments are selected by December 17, 2015, for a ferry flight to ISS in Spring 2016. All communities interested in participating in Mission 9 to ISS are directed to inquire no later than April 30, 2015.

Heritage: There have been ten SSEP flight opportunities to date—SSEP on STS-134 and STS-135, the final flights of Space Shuttles Endeavour and Atlantis; and SSEP Missions 1 through 8 to ISS. A total of 110 communities have participated in the program, reflecting 35 States in the U. S. and 4 Provinces in Canada. Thus far 25 communities have participated in 2, 3, 4, 5 or 6 flight opportunities, reflecting the sustainable nature of the program.

Through the first nine flight opportunities, a total of 45,970 grade 5-15 students were fully immersed in microgravity experiment design and proposal writing, 10,443 flight experiment proposals were received from student teams, and 138 experiments were selected for flight. A total of 113 experiments have flown through SSEP Mission 6.

Currently the 25 experiments of the Mission 7 to ISS Kitty Hawk payload are awaiting transport to ISS, with launch expected in June 2015 on the SpaeeX-7 vehicle launching from Cape Canaveral Air Force Station, Florida, adjoining NASA Kennedy Space Center.

SSEP is the first pre-college STEM education program that is both a U.S. national initiative and implemented as an on-orbit commercial space venture. SSEP is undertaken by the National Center for Earth and Space Science Education (NCESSE) in the U.S. and the Arthur C. Clarke Institute for Space Education internationally. It is enabled through a strategic partnership with NanoRacks LLC, working with NASA under a Space Act Agreement as part of the utilization of the International Space Station as a National Laboratory.

The Smithsonian National Air and Space MuseumCenter for the Advancement of Science in Space (CASIS), and Subaru of America, Inc., are U.S. National Partners on the Student Spaceflight Experiments Program. Magellan Aerospace is a Canadian National Partner on the Student Spaceflight Experiments Program.

Help send the Garden of ETON to space

Back in December I posted about the DreamUP! program created by NanoRacks and FISE ( Foundation for International Space Education), which aims to send STEM projects to the International Space Station.

Chicks in Space is the first team attempting to raise the $15k needed to get an experiment to the station:

Chicks in Space is a group of high school girls who hope to advance space science. We have grown up working on NASA challenges and have had the opportunity to participate in the Conrad Spirit of Innovation – a program aimed at development of innovative ideas. We have created the Garden of ETON – or Extra Terrestrial Organic Nutrition.

This is a hydroponic garden developed to function under conditions of microgravity. It has always been our dream to have an experiment on NASA’s International Space Station. We hope to be able to have the opportunity to launch a reconfigured Garden of ETON – NanoETON – on NanoRacks LLC on NASA’s International Space Station. NanRacks LLC is a company that helps projects like ours get through NASA’s safety and review processes.

When we are not working on space related projects we enjoy golfing and hanging out with our family.

 They have raised about a third of the funding needed to Send the Garden of ETON to Space.
