NASA's Solar Dynamics Observatory, or SDO, lifted off Thursday from Cape Canaveral Air Force Station's Launch Complex 41 on a first-of-a-kind mission to reveal the sun's inner workings in unprecedented detail. The launch aboard an Atlas V rocket occurred at 10:23 a.m. EST. The most technologically advanced of NASA's heliophysics spacecraft, SDO will take images of the sun every 0.75 seconds and daily send back about 1.5 terabytes of data to Earth -- the equivalent of streaming 380 full-length...

NASA has selected four organizations to share approximately $18 million over five years for education and public outreach activities to help inspire the next generation of science leaders and explorers. The cooperative agreements support the astrophysics, heliophysics, planetary and Earth divisions of NASA's Science Mission Directorate, which is providing the funding for the activities. "NASA seeks to work with the best of the nation's science and educational communities to help champion and...

NASA has selected two science proposals to be developed into full missions as part of the agency's Small Explorer, or SMEX, Program. The selections will implement projects that will study our sun and some of the most exotic objects in the universe, such as neutron stars and black holes. Both missions will launch by 2015; the first could launch by the end of 2012. Mission costs will be capped at $105 million each, excluding the launch vehicle. "These two missions demonstrate the value of the...

NASA and the European Space Agency have selected 10 proposals for science instruments to fly aboard a spacecraft that will study the sun from a unique vantage point in space. The European-led mission, called the Solar Orbiter, will be positioned about one-fourth the distance Earth is from the sun. The location ultimately will enhance the ability for scientists worldwide to forecast space weather. Space weather can produce electromagnetic fields on Earth that induce extreme currents in wires,...

NASA scientists will reveal new information and images about our sun and its influence on Earth and the solar system for Sun-Earth Day, recognized each year in conjunction with the spring equinox. The highlight of this year's celebration is a webcast for students and teachers around the world beginning at 1 p.m. EDT, Friday, March 20. This year's theme, "Our Sun, Yours to Discover," celebrates the International Year of Astronomy and emphasizes daytime astronomy. During the live, interactive...

A NASA-funded study describes how extreme solar eruptions could have severe consequences for communications, power grids and other technology on Earth. The National Academy of Sciences in Washington conducted the study. The resulting report provides some of the first clear economic data that effectively quantifies today's risk of extreme conditions in space driven by magnetic activity on the sun and disturbances in the near-Earth environment. Instances of extreme space weather are rare and...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
