A Trip Across the Solar System

|

Right at this moment, robotic probes launched by NASA, the European Space Agency (ESA), and others are gathering information all across the solar system. We currently have spacecraft in orbit around the Sun, Mercury, Venus, Earth, Mars, and Saturn. Several others are on their way to smaller bodies, and a few are heading out of the solar system entirely. Although the Space Shuttle no longer flies, astronauts are still at work aboard the International Space Station, performing experiments and sending back amazing photos. With all these eyes in the sky, I'd like to take another opportunity to put together a recent photo album of our solar system -- a set of family portraits, of sorts -- as seen by our astronauts and mechanical emissaries. This time, we have some closer views of the asteroid Vesta, a visit to the durable (if dusty) Mars rover Opportunity, some glimpses of Saturn's moons, and lovely images of our home, planet Earth.

A view of the Sun on March 7, 2012, seen in extreme ultraviolet wavelengths by the Atmospheric Imaging Assembly aboard NASA's Solar Dynamics Observatory. Looping lines reveal solar plasma that is rising and falling along magnetic field lines in the solar atmosphere, or corona. The brighter prominence at upper left is named solar active region 1429, which has already released several large solar flares, some accompanied by large explosions of solar plasma known as coronal mass ejections.

Comet Lovejoy approaches the sun (left side), interacting the with the sun's corona which is several million degrees, and re-emerges at right, after passing closely by the far side of the Sun. Comet Lovejoy survived what astronomers figured would be a sure death when it danced uncomfortably close to the sun on December 15, 2011. The comet, which was only discovered a couple of weeks before, was supposed to melt as it came so close to the sun that the temperatures around it would hit several million degrees. Astronomers had tracked 2,000 other sun-grazing comets make the same suicidal trip. None had ever survived. (AP Photo/NASA's Solar Dynamics Observatory) #

On December 05, 2011, NASA's MESSENGER spacecraft, in orbit around the planet Mercury, sent back this image of the central peaks of Eminescu Crater. Eminescu crater is 125 kilometers (78 miles) in diameter, and was only recently named - in honor of Mihai Eminescu, an accomplished and influential poet who is still considered the national poet of Romania.

This NASA radar image shows asteroid 2005 YU55, as the 400m (1,300ft) diameter space rock passed by at 3.6 lunar distances from Earth, (about 860,000 miles, or 1.38 million kilometers), near it's closest approach on November 7, 2011. Scientists will be watching for the return of 2005 YU55, due for close flybys in 2041, and again in 2075. (Reuters/NASA/JPL-Caltech) #

On the Moon, the Apollo 15 landing site, imaged from an altitude of 25 km by NASA's Lunar Reconnaissance Orbiter on November 6, 2011. Apollo 15 was the ninth manned mission in the Apollo space program, and the fourth to land on the Moon on July 30, 1971. Commander David Scott and Lunar Module Pilot James Irwin spent three days on the Moon, including lots of time in LRV-1, the first Lunar Rover, which they drove across 17.25 miles (27.76 km) of lunar surface. In this image, the descent stage of Apollo 15 is just right of center, the white spot with a surrounding shadow. Dark tracks to the right lead to the LRV-1, left parked on the moon. The trail of astronaut footprints at center-left surround the ALSEP experiments package. If you look closely at the left edge, you can see rover tracks leading off toward Hadley Rille, some 2km beyond. (NASA) #

Long Island and the New York City area are visible in the lower right quadrant. Philadelphia and Pittsburgh are near the center. Parts of two Russian vehicles parked at the orbital outpost are seen in left foreground. (Reuters/NASA) #

What eight dusty years on Mars will do to a rover. This pair of self-portaits from NASA's Mars Exploration Rover Opportunity shows dust accumulation on the rover's solar panels as the mission approaches its fifth Martian winter. The dust reduces the rover's power supply, and the rover's mobility is limited until the winter is over or wind cleans the panels. The photo on the left side was taken in February of 2005, when Opportunity had only been on the planet for 322 Martian days (sols). The right side was taken in December of 2011, after some 2,800 sols. Total distance driven by Opportunity to date: 34.36 km (21.35 miles) (NASA/JPL) #
In the foreground, the high-gain antenna aboard NASA's Rover Opportunity, as the robotic probe has positioned itself on the rim of Endeavour Crater with an approximate 15-degree northerly tilt for favorable solar energy production during the Martian winter. While positioned for the winter, Opportunity is conducting regular radio Doppler tracking measurements to support geo-dynamic investigations of the planet. (NASA/JPL) #
This image obtained by the framing camera on NASA's Dawn spacecraft shows the south pole of the giant asteroid Vesta. The image was recorded with the framing camera aboard NASA's Dawn spacecraft from a distance of about 2,700 km (1,700 mi). (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA) #
An image of the giant asteroid Vesta, obtained by NASA's Dawn spacecraft as it was spiraling down from its high altitude mapping orbit to low altitude mapping orbit, on November 27, 2011.
