 During its one-year mission, NASA's Wide-field Infrared Survey Explorer,
or WISE, mapped the entire sky in infrared light. Among the multitudes
of astronomical bodies that have been discovered by the NEOWISE portion
of the WISE mission are 20 comets. This collage shows those
20 new comets together in a kind of family portrait. The fuzzy
background in each picture is due to random fluctuations in infrared
light, primarily from dust in our own solar system. Stars cannot be seen
because th... Continue reading...

 NASA engineer Ernie Wright looks on as the first six flight ready James
Webb Space Telescope's primary mirror segments are prepped to begin
final cryogenic testing at NASA's Marshall Space Flight Center. This
represents the first six of 18 segments that will form NASA's James
Webb Space Telescope’s primary mirror for space observations. Engineers
began final round-the-clock cryogenic testing to confirm that the
mirrors will respond as expected to the extreme temperatures of space
prio... Continue reading...

 Commonly known simply as the shuttle, the orbiter is both the brains and
heart of NASA's Space Transportation System. Hence, the STS before the
number of every shuttle flight. About the same size and weight as a DC-9
aircraft, the orbiter contains the pressurized crew compartment (which
can carry
up to seven crew members), the cargo bay and the three main engines
mounted on its aft end. On April 12, 1981, commander John Young and
pilot Robert Crippen roared into space on the first ever ... Continue reading...

 In this image from 2005, NASA's Mars Exploration Rover Opportunity used
its rock abrasion tool on a rock informally named "Gagarin" during the
401st and 402nd Martian days, or sols, of the rover's work on Mars
(March 10 and 11, 2005). This false-color image
shows the circular mark created where the tool exposed the interior of
the rock Gagarin at a target called "Yuri." The circle is about 1.8
inches (4.5 centimeters) in diameter. Gagarin is at the edge of a highly
eroded, small crater ... Continue reading...
