NASA Invites Media to Space Weather Enterprise Forum

NASA Administrator Charles Bolden will deliver the keynote address at the annual Space Weather Enterprise Forum Tuesday, June 4, at the National Oceanic and Atmospheric Administration Auditorium and Science Center, located at 1301 East-West Highway in Silver Spring, Md.

NASA Commercial Crew Partner Boeing Completes New Spacecraft, Rocket Milestones

The Boeing Company of Houston, a NASA Commercial Crew Program (CCP) partner, recently performed wind tunnel testing of its CST-100 spacecraft and integrated launch vehicle, the United Launch Alliance (ULA) Atlas V rocket. The testing is part of NASA's Commercial Crew Integrated Capability (CCiCap) initiative, intended to make commercial human spaceflight services available for government and commercial customers.

Another American High Frontier First: 3-D Manufacturing in Space

In preparation for a future where parts and tools can be printed on demand in space, NASA and Made in Space Inc. of Mountain View, Calif., have joined to launch equipment for the first 3-D microgravity printing experiment to the International Space Station.

Astronauts Would Face High Radiation on Manned Mars Mission

While Curiosity's primary mission was to find out if Mars might ever have been capable of supporting Martian life, the rover has also collected data pertinent for a different kind of life: human beings. Curiosity has kept tabs on radiation levels on Mars as well as during the 253-day, 350-million-mile trip it took to get there. Findings released today indicate that radiation levels an astronaut would receive from a trip to Mars and back would be high: approximately 2/3 of their lifetime reco

Atom by atom, bond by bond, a chemical reaction caught in the act

Scientists have produced remarkable images of carbon atoms and the bonds among them. Resembling glowing textbook diagrams, hydrocarbon molecules are shown in high resolution for the first time before and after bond-breaking, rearrangement, and reforming of bonds during a complex chemical reaction.

Scientists capture first images of molecules before and after reaction

Using atomic force microscopy, chemists for the first time can capture images of molecules before and after they react, which will allow them to better tune reactions to get the products they want. Chemists and physicists joined forces to develop the technique, which could help scientists study and improve catalytic reactions like those used widely in industry to make chemicals or crack oil.

New mathematical model links space-time theories

Researchers at the University of Southampton have taken a significant step in a project to unravel the secrets of the structure of our Universe.

Researchers build two versions of new most accurate clock ever

(Phys.org) —Researchers at the National Institute of Standards and Technology in Boulder Colorado have succeeded in building a record breaking clock—one that has an instability of just one part in 10-18. They describe their new clock in a paper they've uploaded to the preprint server arXiv. In it they suggest that if their clock could somehow be used to gauge the age of the universe, it would be able to do so within just a single second.

Meta-transmitarray offers unprecedented control of light on subwavelength scales

(Phys.org) —The ability to guide, bend and focus light at the nanoscale is a highly sought-after goal in the field of nano-optics. Precise and efficient light control has direct applications in solar cells, holography, nanoscale signal processing, CMOS cameras, and many other areas.

NASA’s Destination Station Exhibit Lands In Seattle

Starting Monday, June 10, residents of Seattle and surrounding areas are invited to experience NASA’s Destination Station exhibit, which showcases what it’s like to live aboard the International Space Station.
