Rosetta View of Earth from Space
The European Space Agency's comet chasing mission Rosetta took these infrared and visible images during its Earth fly-by in early March 2005 while on its way to Comet 67P/Churyumov-Gerasimenko. The images gave the Rosetta team a chance to calibrate its instruments on a real space object to make sure everything was in working order.

Rosetta Launch in 2004
Rosetta successfully lifted off from Europe's Spaceport in Kourou, French Guiana, at 04:17 local time (08:17 CET) on March 2, 2004
Ariane 5 Carrying Rosetta on the Pad
Rosetta was launched in 2004 and has since travelled around the sun five times, picking up energy from Earth and Mars to line it up with its final destination: comet 67P/Churyumov–Gerasimenko.
Rosetta Tested in the LSS
Rosetta was tested in the Large Space Simulator (LSS) at ESA/ESTEC. Rosetta was launched in 2004 and has since travelled around the sun five times, picking up energy from Earth and Mars to line it up with its final destination: comet 67P/Churyumov–Gerasimenko. Image released Dec. 19, 2013.
Testing Rosetta's Solar Array

Rosetta Comet Spacecraft

Rosetta at Comet
Artist's impression of the Rosetta orbiter at comet 67P/Churyumov-Gerasimenko. The image is not to scale. The Rosetta spacecraft measures 105 feet (32 meters) across including the solar arrays, while the comet nucleus is thought to be about 2.5 miles (4 kilometers) wide. Image released Jan. 24, 2014.
U.S. Instruments Aboard Rosetta
Three of NASA's contributions to the European Space Agency's Rosetta mission are pictured here. An ultraviolet spectrometer called Alice (top) will analyze gases in the coma and tail and measure the comet's production rates of water and carbon monoxide and dioxide. It will provide information on the surface composition of the nucleus, and make a potentially key measurement of argon, which will be a big clue about what the temperature was in the primordial solar system when the comet's nucleus originally formed (more than 4.6 billion years ago). Image released Jan. 24, 2014.
Giant Antennas Supporting Rosetta
These aerial photos show instruments at the NASA Deep Space Network complexes, including the giant 230-feet-wide (70-meter-wide) antenna at the Goldstone, California complex (left) and a similar antenna at Canberra, Australia.
