As the launch clock counts down, astronauts in the
space shuttle prepare for the fastest ride of their lives. More powerful
than any plane, train, or automobile, NASA space shuttles boast the
world’s most sophisticated rocket engines: three 14-foot-long main
engines that produce more than 375,000 pounds of thrust each. ...

Knowing what will happen before it happens is no
easy task. That is why new spacecraft and technology are constantly
being tested and refined—including the J-2X engine, which may power the
upper stage of future NASA rockets. Data from tests like these help to
ensure that the next ...

Much is made of the engineering that enables the
complex operations of a rover examining the surface of Mars—and rightly
so. But even the most advanced robotics are useless if, when the rover
rolls out onto the Martian soil, a software glitch causes a
communications breakdown and leaves the ...

Monitoring the health of a machine can be just as
tricky as monitoring the health of a human. Like in the human body, a
variety of subsystems must work together for a machine to function
properly—and a problem in one area can affect the well-being of another.
For example, ...

For the last 25 years, the NASA Advanced
Supercomputing (NAS) Division at Ames esearch Center has provided
extremely fast supercomputing resources, not only for NASA missions, but
for scientific discoveries made outside of NASA as well. The computing
environment at NAS includes four powerful high-performance computer
systems: Pleiades, Columbia, Schirra, and ...

Using the Spitzer Space telescope, NASA scientists
detected light from two Jupiter-sized extrasolar planets for the first
time in 2005. Findings like these are enabled in part by the Science
Mission Directorate at NASA, which conducts scientific research enabled
by access to space—such as Earth science, planetary science,
heliophysics (the ...

To better understand and predict global climate,
scientists look to the Earth’s oceans. Natural forces like wind, storms,
and heat affect ocean surface and sea level, and these changes can shed
light on short- and long-term global climate patterns.

On May 20, 1996, astronauts aboard the Space Shuttle
Endeavor watched as a unique structure unfolded in space like a complex
trick of origami. From the free-flying Spartan satellite the STS-77
crew had released from the shuttle’s cargo hold, a massive circular
antenna inflated into shape. About the size of a ...

Getting to the Moon is, to say the least,
challenging. Being on the Moon, though, is no picnic either. In addition
to the obvious life support and temperature control concerns,
astronauts must contend with another obstacle: the Moon’s surface. This
surface is covered with sharp, abrasive dust, lunar soil, ...
