NASA - National Aeronautics and Space AdministrationPasadena, 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

NASA - National Aeronautics and Space AdministrationWashington, 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.

NASA studies how Fluids move in Microgravity aboard International Space Station

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, 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.

NASA says Astronaut Photographs Inspiring Next Generation of Scientists

NASA - National Aeronautics and Space AdministrationHouston, 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.”

NASA reports International Space Station celebrates New Year 16 Times

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, 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.

NASA takes a look back at 2014

 

Written by David Weaver
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, 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.”

NASA reports International Space Station builds Rachet Wrench with 3-D Printer

 

Written by Joshua Buck
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, 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.”

The ratchet wrench was designed by Noah Paul-Gin, an engineer at Made In Space Inc., a northern California company that NASA contracted to design, build and operate the printer. Paul-Gin created a 3-D model of the ratchet and made several wrenches, such as the one shown here on an identical printer. (Made In Space)

NASA’s Jet Propulsion Laboratory CubeSat program provides big satellite performance in a small package

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Any way you slice it, space exploration — done right — requires an inordinate range of technical expertise.

From designing the spacecraft, the mission proposal and the circuit boards to testing the flight software and putting together budgets, sending something, anything, into the cosmos depends on good people who know their job.

“Although significantly smaller in size, CubeSats contain analogous payloads and subsystems to larger satellites and require similar technical knowledge and resources to traditional flight projects,” said Shannon Statham, an engineer at NASA’s Jet Propulsion Laboratory in Pasadena, California. “The training and experience gained by working on CubeSats are directly applicable to larger missions.”

NASA scientists test Gecko like Grippers in Microgravity

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – There are no garbage trucks equipped to leave the atmosphere and pick up debris floating around the Earth. But what if we could send a robot to do the job?

Scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, are working on adhesive gripping tools that could grapple objects such as orbital debris or defunct satellites that would otherwise be hard to handle.

The gecko gripper project was selected for a test flight through the Flight Opportunities Program of NASA’s Space Technology Mission Directorate. As a test, researchers used the grippers in brief periods of weightlessness aboard NASA’s C-9B parabolic flight aircraft in August.

This is an image of a gecko foot. Researchers at NASA's Jet Propulsion Laboratory have developed a gripping system based on the way that gecko feet are able to stick to surfaces. Just as a gecko's foot has tiny adhesive hairs, the JPL devices have small structures that work in similar ways. (Wikimedia Commons)

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – The most advanced system to date for studying fruit flies in space, NASA’s Fruit Fly Lab, is making its debut aboard the International Space Station.

The Fruit Fly Lab-01 mission, planned to launch to the station in December aboard SpaceX’s fifth commercial resupply services (CRS) mission, is the first of a series of fruit fly investigations NASA plans to conduct.

The fruit fly—a widely studied biological research model—plays a lead role in this study and will help us better understand how spaceflight impairs the body’s ability to fight infections.
