NASA’s
next flagship mission, the James Webb Space Telescope, will carry the
largest primary mirror ever deployed in space. Researchers has borrowed a
page from its segmented mirror design to create a similar example just a
half-inch in diameter. Strangely, the tiny mirror may one day become
the standard for future space telescopes.

NASA
is readying a fleet of four identical spacecraft, the Magnetospheric
Multiscale (MMS) mission, for a 2014 launch to study space weather. The
effort will require the development of highly sensitive spectrometers
and cameras that operate at unprecedented performance levels.

A
researcher working with images from NASA’s Solar Dynamic Observatory
recently saw something he’d never seen before: a pattern of cells in the
sun’s corona. Using a combination of conventional and magnetic imaging
from several satellites and spacecraft, astronomer were able to build a
3D picture of what was happening on the sun’s surface.

According
to NASA scientist Dr. Nicholas Schmerr, a layer of partially molten
rock about 22 to 75 miles underground can't be the only mechanism that
allows continents to gradually shift their position over millions of
years. He contends that because his research has revealed this melt-rich
layer to be spotty, another cause must exist for the movement of plates
over the mantle.

New observations from a spacecraft orbiting Mercury have revealed that the tiny, pockmarked planet harbors a highly unusual interior—and the craft's glimpse of Mercury's surface topography suggests the planet has had a very dynamic history.

In
October 2010, a neutron star near the center of our galaxy erupted with
hundreds of X-ray bursts that were powered by a barrage of
thermonuclear explosions on the star's surface. NASA's Rossi X-ray
Timing Explorer captured the month-long fusillade in high detail,
identifying behavior not seen in the previous 100 neutron star
observations in the past 30 years.

A
recent study at NASA’s Goddard Space Flight Center analyzed samples
from 14 carbon-rich meteorites with minerals that had experienced
temperatures more than 2,000 F. Although the researchers have found
amino acids in carbon-rich meteorites before, they weren’t expecting to
find them in minerals that had experience enough heat to destroy them.

Using
the most robust and longest duration satellite dataset of Arctic sea
ice available, researchers at NASA have built one of the most complete
pictures of how the Arctic’s supply is changing over time. The study
reveals the rate of disappearance of the old and thickest sea ice, which
typical survives the cyclical summer melt season.

In
the last ten years, scientists have shown that it is possible to detect
falling snow and measure surface snowpack information from the vantage
point of space. But there remains much that is unknown about the fluffy
white stuff. A team from NASA and Environment Canada are hoping their
Global Precipitation Measurement satellite and ground mission will set
new standards and bring global measurements every three hours.

Coinciding
with a peak in solar activity, NASA Goddard Space Flight Center’s Space
Weather Laboratory will soon simultaneously produce as many as 100
computerized forecasts by calculating multiple possible parameters,
improving our ability to predict the impact of solar storms. Currently,
just one set of conditions is used to anticipate solar-storm activity.
