NASA : NASA's Orion Spacecraft is Ready to Feel the Heat


Engineers complete installing the heat shield on NASA’s Orion spacecraft
Engineers completed installing the heat shield on NASA’s Orion spacecraft ahead of its first trip to space in December. The flight test will send an uncrewed Orion 3,600 miles into space before returning it to Earth for the splashdown in the Pacific Ocean. The heat shield will help protect the Orion crew vehicle from temperatures of about 4,000 degrees Fahrenheit during its reentry into Earth’s atmosphere.

NASA and Lockheed Martin engineers have installed the largest heat shield ever constructed on the crew module of the agency's Orion spacecraft. The work marks a major milestone on the path toward the spacecraft's first launch in December.
"It is extremely exciting to see the heat shield in place, ready to do its job," said Mark Geyer, Orion Program manager at NASA's Johnson Space Center in Houston. "The heat shield is such a critical piece, not just for this mission, but for our plans to send humans into deep space."
The heat shield is made of a coating called Avcoat, which burns away as it heats up in a process called ablation to prevent the transfer of extreme temperatures to the crew module. The Avcoat is covered with a silver reflective tape that protects the material from the extreme cold temperatures of space.
Orion’s flight test, or Exploration Flight Test-1, will provide engineers with data about the heat shield's ability to protect Orion and its future crews from the 4,000-degree heat of reentry and an ocean splashdown following the spacecraft’s 20,000-mph reentry from space.
Data gathered during the flight will inform decisions about design improvements on the heat shield and other Orion systems, and authenticate existing computer models and new approaches to space systems design and development. This process is critical to reducing overall risks and costs of future Orion missions -- missions that will include exploring an asteroid and Mars.
Orion's flight test also will provide important data for the agency’s Space Launch System (SLS) rocket and ocean recovery of Orion. Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, have built an advanced adapter to connect Orion to the United Launch Alliance Delta IV Heavy rocket that will launch the spacecraft during the December test. The adapter also will be used during future SLS missions. NASA’s Ground Systems Development and Operations Program, based at Kennedy Space Center in Florida, will recover the Orion crew module with the U.S. Navy after its splashdown in the Pacific Ocean.
The heat shield was manufactured at Lockheed Martin's Waterton Facility near Denver. Construction was completed at Textron Defense Systems near Boston before the heat shield was shipped to the Operations and Checkout Building at Kennedy, where Orion is being assembled.
In the coming months, the Orion crew and service modules will be joined and put through functional tests before the spacecraft is transported to Kennedy’s Payload Hazardous Servicing Facility for fueling. The spacecraft then will be transferred to the Launch Abort System (LAS) Facility to be connected to the LAS before making the journey to Cape Canaveral’s Space Launch Complex 37 for pad integration and launch operations.

Next Generation of Explorers Takes the Stage
NASA, International Community United in Support of Bold Space Exploration Program
NASA Administrator Charles Bolden on Tuesday formally welcomed the eight newest candidates to the astronaut corps and unveiled a space exploration roadmap that makes clear the global community is working together on a unified deep space exploration strategic plan, with robotic and human missions to destinations that include near-Earth asteroids, the moon and Mars.
At NASA's Johnson Space Center in Houston, the members of the 2013 astronaut class spoke with reporters about their new roles and their desire to help the agency push the boundaries of exploration and travel to new destinations in the solar system. These next-generation American astronauts will be among those who will have the opportunity to fly on new commercial space transportation systems that are now under development. They also will be among those to plan and perhaps carry out the first-ever human missions to an asteroid and Mars.
"This class joins a distinguished and elite group of Americans who have carried out historic missions to the moon, deployed space telescopes and built an orbiting laboratory the size of a football field, where U.S. astronauts have continuously lived, worked and conducted research for more than a dozen years now," said Bolden. "They are being asked to carry on this extraordinary legacy and ensure the United States remains the world's leader in exploration and scientific discovery -- carrying with them America's hopes, dreams and curiosity deep into space, first to an asteroid and one day on to Mars."
The 2013 astronaut candidate class comes from a pool of 6,000 applicants, the second largest in NASA history. Half of the selectees are women, making this the highest percentage of female astronaut candidates ever selected for a single class. The group will participate in extensive technical training at space centers and remote locations around the world to prepare for missions beyond low-Earth orbit.
Bolden also spoke about the updated Global Exploration Roadmap (GER), released publicly Tuesday. The roadmap reflects the work of 12 space agencies of the International Space Exploration Coordination Group. It highlights the international space community's shared interest in pursuing deep space exploration and reflects the degree of international cooperation on a unified deep space exploration strategic roadmap.
The shared global vision, as laid out in the GER, includes:
-- an examination of the critical part the International Space Station plays in deep space exploration;
-- robotic and human missions to destinations that include near-Earth asteroids, the moon and Mars;
-- validation of the vital role of NASA's asteroid mission in advancing the capabilities needed to explore Mars and the economic and societal value such exploration can bring; and
-- a conceptual scenario that demonstrates how missions in the lunar vicinity, including NASA's asteroid initiative, pave the way for international missions to Mars in the 2030s, while enabling important discoveries along the way.

NASA Signs Agreement to Develop Nasal Spray for Motion Sickness
HOUSTON -- NASA's Johnson Space Center in Houston and Epiomed Therapeutics Inc. of Irvine, Calif., have signed an agreement to develop and commercialize a NASA-crafted, fast-acting nasal spray to fight motion sickness.

Under the Space Act Agreement, Epiomed will formulate the drug, called intranasal scopolamine, or INSCOP. Astronauts often experience motion sickness in space. As a result, NASA has conducted extensive research into the causes and treatments for the condition. Scopolamine is effective and can be administered as a tablet or injected. With a precise dosage, the NASA spray formulation has been shown to work faster and more reliably than the oral form.

"NASA and Epiomed will work closely together on further development of INSCOP to optimize therapeutic efficiency for both acute and chronic treatment of motion sickness which can be used by NASA, the Department of Defense and world travelers on land, in the air and on the seas," said Lakshmi Putcha, developer of the innovative treatment strategy at Johnson.

A gel formulation of INSCOP was developed and tested under a Space Act Agreement between Johnson and the Naval Aerospace Medical Research Laboratory in Pensacola, Fla. Results from that trial were published in the journal Aviation, Space and Environmental Medicine in April 2010 that suggest INSCOP is a fast-acting and reliable way to prevent and treat motion sickness.

The U.S. Navy is working on an agreement with Epiomed to test the nasal spray. NASA and Epiomed will collaborate on clinical trials related to the Federal Drug Administration requirements. NASA is transferring sponsorship of future clinical trials and FDA approvals to Epiomed, which will supply the product for use by NASA and others.

General Health/ Dietary Guidelines: Fish (intake) and Bone Loss

Data from the International Space Station has documented a relationship between fish intake and bone loss in astronauts (that is, those that ate more fish lost less bone). Related findings have also been shown in two sets of ground-based space flight simulation studies evaluating the role of omega-3 fatty acids, the fatty acid found in fish. In a bed rest study, the rate of bone breakdown was related to omega-3 fatty acid intake (again, more omega 3, less bone breakdown). In a series of cell culture studies, cells that break down bone were less active when omega-3 fatty acids were added. While more detailed studies in flight are required, this has broad implications for all Americans, especially in light of osteoporosis and other bone diseases, which affect millions of people. This research was provided by Scott Smith.

General Health/ Dietary Guidelines: Vitamin D Requirements: From the ISS to Antarctica to North America

NASA Human Research Program has provided research to define vitamin D requirements for spaceflight contributed to the new dietary recommendations of vitamin D for North Americans. Because spacecraft shields astronauts from ultraviolet light, and the space food system is low in vitamin D, it has been determined crews need extra vitamin D to maintain health. To better understand the vitamin D requirement in this unique environment, NASA, in collaboration with the National Science Foundation, conducted two vitamin D supplementation studies in people wintering in Antarctica, when sunlight is limited for an average of six months. Published study results were featured in the 2011 re-evaluation of vitamin D requirements for North America by the Institute of Medicine. The Antarctic studies also characterized that body mass index can affect vitamin D status and response to vitamin D intake. Specifically, it was found that people with a higher body mass index require more vitamin D in order to achieve the same blood concentration of vitamin D as someone with a lower body mass index. These results have significant importance for the general population, where more than 1/3 of Americans are obese. This research was provided by Scott Smith.

Water Purification: Filtering Apparatus and Method of Use (Patent #7935259)

This water filtering innovation is used to eliminate contaminants from water supplies. Originally designed for purification of wastewater for reuse aboard the International Space Station (ISS), the technology can be used in numerous situations on Earth to obtain potable, medical-grade water from contaminated supplies. The unique aspect of the technology is its use of acoustics rather than pressure to drive water through the filtration system. The filter is made of small-diameter carbon nanotubes embedded within plastic or metallic assemblies. The small diameter of the nanotubes allows only water molecules to pass through, leaving behind any larger molecules and contaminants. The invention also may be used to remove water from chemical compounds, such as removing water from alcohols. The device requires less power than conventional filtration systems and is well-suited to a variety of water purification needs. The innovation is:
  • Effective: Produces clean water by eliminating contaminants
  • Efficient: Requires less power than conventional filtration systems, enabling remote operation and solar power options
  • Easy to clean: Features non-clogging technology
  • Flexible: Does not depend on gravity for water to flow through the system
  • Scalable: Allows for use of a single filter or a large bank of integrated filters, depending on filtration needs
  • Affordable: May be assembled using low-cost, non-degrading, easily obtained materials
  • Straightforward: Facilitates automated production of all filter components
  • Widely applicable: Suits applications for a variety of water processing needs, ranging from industrial to consumer applications
Although the technology is currently under development, once fully developed it could enable recycling of water on the ISS and other spacecraft. On the ISS, alcohol and impurities in onboard water systems shorten the life of sorbent beds and negatively affect microscale machinery. Current methods of dealing with these contaminants are not completely efficient and result in equipment degradation and failure over time. For instance, the current method of dealing with alcohol in the water on the ISS is catalytic in nature and yields hazardous byproducts such as formaldehyde. The ISS regularly dumps unusable water, necessitating that tons of water be flown there every year to replenish the supply. A system that could separate alcohol from the water, making it suitable for reuse aboard the ISS, would save NASA millions of dollars. As NASA plans for human exploration of Mars, a host of technologies will be needed to protect travelers from the hazards of deep space. This innovation could offer significant benefits for water purification applications and contribute to NASA’s efforts to develop breakthrough technologies that enable deep space exploration. Non-Aerospace Commercialization Uses: The potential benefits of this technology are applicable for a raft of Earth-based water processing needs. End-users could include both industrial and municipal entities that plan to reuse recycled water, desalinate brackish or sea water, or treat surface or ground water for potable use. In addition, the technology could be incorporated into portable or handheld water filtration units, suitable for use in remote locations. This research is provided by Lillian Gavalas.

Astronomy:Teachers Fly Experiments on NASA Reduced Gravity Flights

Hi My Friends: AL VUELO DE UN QUINDE EL BLOG., The teachers flew aboard an aircraft that flies parabolic flight paths, which create brief periods of weightlessness. It is a key component of NASA's astronaut training protocol. The teachers were selected for the flights through NASA's Teaching from Space and Explorer School Programs. Teachers Fly Experiments on NASA Reduced Gravity Flights

HOUSTON -- More than 70 teachers had an opportunity to experience what it feels like to float in space as they participated in the Reduced Gravity Education Flight Program at NASA's Johnson Space Center in Houston last week.

The teachers flew aboard an aircraft that flies parabolic flight paths, which create brief periods of weightlessness. It is a key component of NASA's astronaut training protocol.

The teachers were selected for the flights through NASA's Teaching from Space and Explorer School Programs. NASA Associate Administrator for Education and two-time space shuttle astronaut Leland Melvin also participated in some of the flights and shared first-hand with the participants his experiences in astronaut training.

"The enthusiasm among our teachers participating in the reduced gravity flights is contagious," Melvin said. "I know it will add a new dimension to their teaching as they engage their students in science, technology, engineering and mathematics studies."

Also participating in the flights was Mark Riccobono, executive director of the National Federation of the Blind's Jernigan Institute. Riccobono is blind. NASA has worked with the National Federation of the Blind in a variety of capacities during the past 10 years to share the excitement and inspiration of the agency's missions and programs with those who are visually impaired.

"NASA education always is looking for ways to make our offerings available to the widest audience possible," Melvin said. "Mark Riccobono's flight represents a new chapter in our commitment to sharing the excitement of NASA's mission with the blind community." The Teaching from Space Program offers educational opportunities that use the unique assets of NASA's human spaceflight mission to engage the education community and create space-related learning opportunities.

Teachers used the event to work with their students to propose, design and build the experiments they took on the flights. Fourteen teams comprising 40 teachers from NASA Explorer Schools also participated as part of the 2011 School Recognition Award for their contributions to science, technology, engineering and mathematics, or STEM.

They conducted microgravity experiments provided by NASA. The Reduced Gravity Education Flight Program continues NASA's investment in U.S. education by helping attract and retain students in STEM disciplines critical to future space exploration. To learn more about NASA's education activities,
