And friend Murchison, with his chronometer in hand, his eye fixed on the needle, his finger on the electric apparatus, is counting the seconds preparatory to launching us into interplanetary space
What guide had I through the trackless waste of interplanetary space
? What assurance that I might not as well be hurtled to some far-distant star of another solar system, as to Mars?
"RAD was designed for the science mission to characterize radiation levels on the surface of Mars, but an important secondary objective is measuring the radiation on the almost nine-month journey through interplanetary space
, to prepare for future human exploration," Hassler added.
Above that reddish band lies the corona, spreading its tentacles into interplanetary space
No one had imagined that the wind could retain the pattern of solar vibrations as it travels through turbulent regions of interplanetary space
Second, an estimated one billion tons of rock have traveled from Mars to Earth, blasted loose by asteroid impacts and then traveling through interplanetary space
before striking Earth's surface.
A shock forms there after the flare violently expels plasma at supersonic speeds, accelerating coronal material into interplanetary space
. According to theory, this material follows interplanetary magnetic-field lines to Earth, where it generates auroras and throws power grids and communications networks into disarray.
To achieve that goal, NASA engineers in late May began a risky set of maneuvers never before attempted in interplanetary space
. Because Magellan lacks the power to alter its own orbit, NASA scientists are letting the drag of Venus' atmosphere do the work for them.
NASA will launch the Mars Atmosphere and Volatile Evolution Mission (MAVEN) in 2013 to investigate processes that could have stripped the gas from the top of the atmosphere into interplanetary space
Close inspection revealed a deep layer of shocked and melted rock--convincing evidence, say the team's members, that Bedout marks the spot where Earth took a mighty hit from interplanetary space
. An isotopic assay has since yielded an age of 250.7 [+ or -] 4.3 million years for Bedout's shattered rock, closely matching the extinction's date.
When these elongated gas clouds, normally held in place for days or hours by magnetic fields, erupt in the same region as solar flares, they spew out material that carries the sun's high-energy particles into interplanetary space
. Researchers know solar prominences can cause geomagnetic storms when they intercept Earth's magnetic field, interfering with communications and electric power transmission.
Such charged particles can blow apart biological molecules such as DNA and would easily rip through the aluminum shielding of a spacecraft traveling through interplanetary space
