Washington, D.C. – Alzheimer’s disease is a global problem. In the United States alone, more than 5 million people have the disease and a new diagnosis is made every 67 seconds—numbers that are just a fraction of worldwide totals. Among medical researchers, Alzheimer’s is a top priority.
Researchers working with astronauts on the International Space Station are embarking on a mission to discover the origin of Alzheimer’s. Although the details are still a little fuzzy, researchers believe that Alzheimer’s and similar diseases advance when certain proteins in the brain assemble themselves into long fibers that accumulate and ultimately strangle nerve cells in the brain.
Washington, D.C. – NASA and Bigelow Aerospace are preparing to launch an expandable habitat module to the International Space Station this year. The agency joined Bigelow Thursday at its Las Vegas facility to mark completion of the company’s major milestones.
The Bigelow Expandable Activity Module, or BEAM, leverages key innovations in lightweight and compact materials, departing from a traditional rigid metallic structure. In its packed configuration aboard SpaceX’s Dragon spacecraft launched on a Falcon 9 rocket, the module will measure approximately 8 feet in diameter.

Pasadena, CA – Four new NASA Earth-observing missions are collecting data from space – with a fifth newly in orbit – after the busiest year of NASA Earth science launches in more than a decade.
On February 27th, 2014, NASA and the Japan Aerospace Exploration Agency (JAXA) launched the Global Precipitation Measurement (GPM) Core Observatory into space from Japan. GPM and the other new missions are making observations and providing new insights into global rain and snowfall, atmospheric carbon dioxide, ocean winds, clouds and tiny airborne particles called aerosols. Three of the new Earth missions are managed by NASA’s Jet Propulsion Laboratory, Pasadena, California.

Pasadena, CA – Over the past 12 months NASA has added five missions to its orbiting Earth-observing fleet – the biggest one-year increase in more than a decade. NASA scientists will discuss early observations from the new missions and their current status during a media teleconference at 11:00am PST (2:00pm EST) Thursday, February 26th.
New views of global carbon dioxide, rain and snowfall, ocean winds, and aerosol particles in the atmosphere will be presented during the briefing.
NASA Astronauts to conduct Spacewalks to ready International Space Station for Commercial Transport Ships

Washington, D.C. – Change is on the horizon for the International Space Station as three upcoming spacewalks prepare the orbiting laboratory for future arrivals by U.S. commercial crew spacecraft.
The spacewalks are designed to lay cables along the forward end of the U.S. segment to bring power and communication to two International Docking Adapters slated to arrive later this year. The new docking ports will welcome U.S. commercial spacecraft launching from Florida beginning in 2017, permitting the standard station crew size to grow from six to seven and potentially double the amount of crew time devoted to research.

Washington, D.C. – The next time you pour yourself a glass of water, pause before you drink it. First, swirl the clear liquid around the glass. Gently slosh it back and forth. Tap the glass on the tabletop, and watch the patterns that form on the surface.
Now imagine the same exercise … in zero gravity. Would the waves and ripples look the same? Would the liquid slosh more, or less? Faster, or slower?
NASA engineers spend a surprising amount of time asking themselves these same questions.

Houston, TX – Students from Connetquot High School in Bohemia, New York, used astronaut imagery of Earth to compare impact craters on Earth with those on other planets. The images were provided through the Expedition Earth and Beyond (EEAB) program, which connects students in grades 5 and higher with pictures taken by astronauts aboard the International Space Station.
“The images provide a hook for students to formulate questions, think about how to collect and analyze data, and then draw their own conclusions,” says EEAB Director Paige Graff. “The whole idea is authentic science you can do in the classroom, to give students an experience based on their interests and motivation.”
Washington, D.C. – The Expedition 42 crew orbiting Earth on the International Space Station gets the opportunity to celebrate New Year’s Eve a whopping 16 times as it circles the globe at 17,500 miles an hour.
Commander Barry “Butch” Wilmore and his crew, which includes NASA’s Terry Virts, Russian cosmonauts Elena Serova, Alexander Samoukutyaev and Anton Shkaplerov, and European Space Agency astronaut Samantha Cristoforetti, say they plan to celebrate with fruit juice toasts.

Washington, D.C. – In 2014, NASA took significant steps on the agency’s journey to Mars — testing cutting-edge technologies and making scientific discoveries while studying our changing Earth and the infinite universe as the agency made progress on the next generation of air travel.
“We continued to make great progress on our journey to Mars this year, awarding contracts to American companies who will return human space flight launches to U.S. soil, advancing space technology development; and successfully completing the first flight of Orion, the next deep space spacecraft in which our astronauts will travel,” said NASA Administrator Charles Bolden. “We moved forward on our work to create quieter, greener airplanes and develop technologies to make air travel more efficient; and we advanced our study of our changing home planet, Earth, while increasing our understanding of others in our solar system and beyond.”

Washington, D.C. – The International Space Station’s 3-D printer completed the first phase of a NASA technology demonstration by printing a tool with a design file transmitted from the ground to the printer. The tool was a ratchet wrench.
“For the printer’s final test in this phase of operations, NASA wanted to validate the process for printing on demand, which will be critical on longer journeys to Mars,” explained Niki Werkheiser, the space station 3-D printer program manager at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “In less than a week, the ratchet was designed, approved by safety and other NASA reviewers, and the file was sent to space where the printer made the wrench in four hours.”
