Why does this large crater on Mercury have two rings and a smooth floor? No one is sure. The unusual feature called Vivaldi Crater spans 215 kilometers and was imaged again in great detail by ESA's and JAXA's robotic BepiColombo spacecraft on a flyby earlier this month.
Messenger Launch
14.08.2004
Streaking into the early morning sky on August 3rd, a Delta II rocket launches NASA's Messenger spacecraft on an interplanetary voyage to Mercury. Scheduled to become the first probe to orbit Mercury, Messenger will begin by looping through the inner Solar System in a series of close flybys of planet Earth and Venus.
Cassini To Venus
16.10.1997
NASA's Saturn Explorer Cassini with ESA's Titan Probe Huygens attached successfully rocketed into the skies early yesterday morning. The mighty Titan 4B Centaur rocket is seen here across the water gracefully arcing away from Launch Complex 40 at Cape Canaveral Air Station.
Rosetta s Rendezvous
7.08.2014
On August 3rd, the Rosetta spacecraft's narrow angle camera captured this stunning image of the nucleus of Comet 67P/Churyumov-Gerasimenko. After 10 years and 6.5 billion kilometers of travel along gravity assist trajectories looping through interplanetary space, Rosetta had approached to within 285 kilometers of its target.
Sail On Stardust
25.01.2001
Spacecraft on long interplanetary voyages often use the planets themselves as gravitational "sling shots" to boost them along their way. Launched in February of 1999 on a historic voyage to a comet, the Stardust spacecraft is no different.
Cassini to Venus
3.07.2004
Saturn Orbiter Cassini with Titan Probe Huygens attached rocketed into early morning skies on October 15, 1997. The mighty Titan 4B Centaur rocket is seen here across the water, arcing away from Launch Complex 40 at Cape Canaveral Air Station.
New Horizons at Jupiter
4.12.2003
Headed for the first close-up exploration of the Pluto-Charon system and the icy denizens of the Kuiper belt, NASA's New Horizons spacecraft is pictured here in an artist's vision of the robot probe outward bound.
Parker vs Perseid

The brief flash of a bright Perseid meteor streaks across the upper right in this composited series of exposures made early Sunday morning near the peak of the annual Perseid meteor shower.
Farther Along

What is humanity's most distant spacecraft? Launched in 1977, Voyager 1 now holds that distinction at 17.5 billion kilometers from the Sun. That corresponds to 16 light-hours or 117 Astronomical Units (AU). This...
