Biosphoto | 2484495 | Illustration of astronauts setting up a base on the Martian surface around their lander vehicle. The first human visitors to Mars would face an environment nearly as hostile as the Earth's Moon. While Mars has an atmosphere, it contains no breathable oxygen and is so thin that the surface air pressure is about the same as the Earth's 18 miles above sea level. To venture outside, humans would need hardy suits that would supply pressure, oxygen, moisture, warmth, and insulate them from the fine martian dust that may be both abrasive and chemically reactive. Even with these precautions, humans would still be vulnerable to radiation from solar storms and the continual rain of interstellar cosmic rays. | © Walter Myers / Stocktrek Images / Biosphoto

Biosphoto | 1632193 | Test of a telescope mirrors in deep cold USA ; Into the Looking Glass<br>Recently, technicians at NASA's Marshall Space Flight Center in Huntsville, Ala., completed a series of cryogenic tests on six James Webb Space Telescope beryllium mirror segments at the center's X-ray & Cryogenic Facility. During testing, the mirrors were subjected to extreme temperatures dipping to -415 degrees Fahrenheit, permitting engineers to measure in extreme detail how the shape of the mirror changes as it cools.<br><br>The Webb telescope has 18 mirrors, each of which will be tested twice in the Center's X-ray & Cryogenic Facility to ensure that the mirror will maintain its shape in a space environment -- once with bare polished beryllium and then again after a thin coating of gold is applied.<br>The cryogenic test gauges how each mirror changes temperature and shape over a range of operational temperatures in space. This helps predict how well the telescope will image infrared sources.<br><br>The mirrors are designed to stay cold to allow scientists to observe the infrared light they reflect using a telescope and instruments optimized to detect this light. Warm objects give off infrared light, or heat. If the Webb telescope mirror is too warm, the faint infrared light from distant galaxies may be lost in the infrared glow of the mirror itself. Thus, the Webb telescope's mirrors need to operate in a deep cold or cryogenic state, at around -379 degree Fahrenheit. | © N.A.S.A. / Biosphoto

Biosphoto | 2484586 | In this image, the Dawn spacecraft's three xenon electrostatic ion thrusters can be seen emitting ionized xenon's characteristic blue/magenta glow, gently propelling the probe toward the dwarf planet Ceres. While the ion engines have relatively low specific thrust (about equal to the weight of a few sheets of paper), they can operate continuously for long periods making efficient use of the approximately 1,000 pounds of xenon propellant onboard. The wing-like solar arrays produce about 1,300 watts for probe's propulsion and other electrical systems. . While no close-up observations have yet been made of Ceres itself, here it is rendered as appearing similar to a much smaller version of the Earth's Moon, heavily cratered with the addition of surface water ice and hypothesized plumes of ice crystals from water geysers on its surface. . In February 2015 the unmanned Dawn spacecraft is scheduled to arrive at the dwarf planet Ceres. The 65 foot long, 2.5 ton probe was launched from the Earth in 2007, passed Mars in 2009, and went into orbit around the protoplanet Vesta in July 2011 where it stayed until September 2012. Once in orbit around Ceres, Dawn is expected to operate for about a year making observations of this largest object in the asteroid belt. | © Walter Myers / Stocktrek Images / Biosphoto

Biosphoto | 2481460 | A pass of the International Space Station on the evening of January 26, 2019. The ISS is moving from right to left, southwest to southeast. . . The ISS faded and reddened naturally into sunset at top left in Taurus. Just before it did that it passed through the Hyades star cluster and just missed Aldebaran. . . The ISS seemed to track along the ecliptic here, made somewhat visible by the faint arc of the zodiacal light reaching up from the horizon at right and stretching across the sky to the upper left. The ISS coincidentally travelled parallel to, but just below the zodiacal light, which follows the ecliptic. . . Some red streaks of airglow are also visible, and I emphasized those in the colour correction to make a more colourful sky. I did the opposite to the light polluted clouds! But their yellow remains. | © Alan Dyer / Stocktrek Images / Biosphoto

Biosphoto | 2484492 | Unlike the rolling volcanic plains of the north, the southern half of Mars is dominated by older, heavily cratered highlands. The distinctly lunar-like terrain of Terra Sirenum belies the fact that, unlike the Earth's Moon, Mars has an active atmosphere. . In this rendering the perspective is from an altitude of about 30 miles and about 30 degrees from Mars' south pole. The large crater with a central peak at the 2 o'clock position near the horizon is Liu Hsin, with a diameter of 80 miles. Just beyond Liu Hsin is the southern rim of a much larger crater named Copernicus, with a diameter of 180 miles. To the west, high-flying cirrus clouds of water ice crystals form complex patterns in the tenuous carbon dioxide atmosphere. | © Walter Myers / Stocktrek Images / Biosphoto

Biosphoto | 2484510 | A full Neptune washes Triton's frozen surface with an indigo light, the only source of illumination on this now Triton's dark side. Fortuitous alignment of the Sun, Triton and Neptune causes this satellite's shadow to fall on Neptune's distant cloud tops 220 thousand miles away. This view is from within a deep, crater-like depression on Triton's northern hemisphere. . There are many such crater-like depressions on Triton's northern hemisphere. While these depressions look like impact craters, their similar size and spacing suggest that they were created by some other process. Their origin is still unknown, but may involve local melting and collapse of the icy surface. The scarcity of impact craters suggest that this surface is relatively young by solar system standards, probably less than a few billion years old. The depression in this image is about 15 miles in diameter; the ridge on the horizon is approximately seven miles from the mesa in the foreground. | © Walter Myers / Stocktrek Images / Biosphoto

Biosphoto | 2484572 | This is how auroras on Jupiter's north pole might look from a distance of about a quarter million miles. On the Sunlit side can be seen churning clouds of ammonia ice, ammonium hydrosulfide, and water ice. The dark side reveals a dazzling aurora and brilliant flashes of lightning hundreds of times brighter than lightning on Earth. . Unlike Earth's north and south pole auroras which are powered by charged particles from the Sun, auroras on Jupiter are driven by particles emitted by Jupiter's volcanic moon Io. Io in fact leaves a distinct auroral footprint on Jupiter's poles, seen here as a whitish dot with a trailing, comet-like tail at the seven 0'clock position. Jupiter's moons Europa and Ganymede also have corresponding, albeit fainter footprints on the far side of the larger auroral oval. | © Walter Myers / Stocktrek Images / Biosphoto
