Some people worry that a gigantic "killer solar flare" could hurl enough energy to destroy Earth, but this is not actually possible.
The launch of a NASA Terrier-Improved Orion sounding rocket on May 9 brought to an end a very successful campaign studying ionospheric activity and its impact on radio, communication and navigation signals.
NASA's twin Voyager spacecraft are on the verge of plunging into interstellar space -- the space between stars -- and two new Web tools let the public fly along.
Since it first provided images of the sun in spring 2010, SDO has had virtually unbroken coverage of the sun's rise toward solar maximum.
The EUNIS experiment was successfully launched at 1:30 pm EDT on April 23, 2013 from the White Sands Missile Range in New Mexico. Preliminary data shows that the experiment performed as planned.
IRIS spacecraft arrives at VAFB for final preparations for a NET May 28 launch aboard a Pegasus rocket.
SLAMS, or short large amplitude magnetic structures, have been spotted in the froth of waves in front of Earthspace as it moves through the solar system. They create a magnetic mirror reflecting fast ion beams into space.
On April 16, 2008, a suite of NASA instruments was launched to study a unique region of space: the electrically charged portion of the upper atmosphere called the ionosphere, a region crucial for radio communications.
NASA sounding rockets are taking science to the Earth’s ionosphere to study radio frequency propagation as well as space weather and its impact on communication and navigation systems, during the 2013 Kwajalein launch campaign.
In October 2011, a NASA-funded sounding rocket called CHAMPS flew up through noctilucent ice clouds to measure the meteoric smoke that seeds the clouds.
