Curiosity Rover Lifts Off for Mars

Explanation: Next stop: Mars. This past weekend the Mars Science Laboratory carrying the Curiosity Rover blasted off for the red planet atop an Atlas V rocket from Cape Canaveral, Florida, USA, as pictured above. At five times the size of the Opportunity rover currently operating on Mars, Curiosity is like a strange little car with six small wheels, a head-like camera mast, a rock crusher, a long robotic arm, and a plutonium power source. Curiosity is scheduled to land on Mars next August and start a two year mission to explore Gale crater, to help determine whether Mars could ever have supported life, and to help determine how humans might one day visit Earth’s planetary neighbor.
The View from Chajnantor

Explanation: From an altitude of over 5,000 meters, the night sky view from Chajnantor Plateau in the Chilean Andes is breathtaking in more ways than one. The dark site’s rarefied atmosphere, at about 50 percent sea level pressure, is also extremely dry. That makes it ideal for the Atacama Large Millimeter/submillimeter Array (ALMA) designed to explore the universe at wavelengths over 1,000 times longer than visible light. Near the center of the the panoramic scene, ALMA’s 7 and 12 meter wide dish antennas are illuminated by a young Moon nestled in the arc of the Milky Way. ALMA’s antenna configurations are intended to achieve a resolution comparable to space telescopes by operating as an interferometer. At left, a meteor’s streak and the Milky Way’s satellite galaxies, the Large (bottom) and Small Magellanic Clouds grace the night.
A Picturesque Venus Transit

Explanation: The rare transit of Venus across the face of the Sun in 2004 was one of the better-photographed events in sky history.
Apollo 11 Customs and Immigration Form
In what is perhaps the best application of bureaucracy to date, Neil Armstrong, Buzz Aldrin, and Michael Collins declared all their moon rocks and moon dust when they arrived in Hawaii after splashing down in the Pacific Ocean.
(Note: while the form is real, the astronauts were made to fill it out as a joke.)

Explanation: Space shuttle orbiter Atlantis left planet Earth on Friday, July 8, embarking on the STS-135 mission to the International Space Station. The momentous launch was the final one in NASA’s 30 year space shuttle program that began with the launch of the first reusable spacecraft on April 12, 1981. In this reflective prelaunch image from July 7, Atlantis stands in a familiar spot on the Kennedy Space Center’s pad 39A, after an early evening roll back of the pad’s Rotating Service Structure. The historic orbital voyages of Atlantis have included a Hubble Space Telescope servicing mission, deployment of Magellan, Galileo, and the Compton Gamma-ray Observatory, and seven trips to the Russian space station Mir. Scheduled to dock once again with the International Space Station on Sunday, Atlantis has now made its 33rd and final trip to orbit.
Explanation: Thunderstorms almost spoiled this view of the spectacular June 15 total lunar eclipse. Instead, storm clouds parted for 10 minutes during the total eclipse phase and lightning bolts contributed to the dramatic sky. Captured with a 30 second exposure the scene also inspired what, in the 16 year history of Astronomy Picture of the Day, the editor considers may be the best title yet for a picture (title credit to Chris K.). Of course, the lightning reference clearly makes sense, and the shadow play of the dark lunar eclipse was widely viewed across planet Earth in Europe, Africa, Asia, and Australia. The picture itself, however, was shot from the the greek island of Ikaria island at Pezi. That area is known as “the planet of the goats” because of the rough terrain and strange looking rocks.
Explanation: What has the Cassini orbiter seen since arriving at Saturn? The above music video shows some of the highlights. In the first time-lapse sequence (00:07), a vertical line appears that is really Saturn’s thin rings seen nearly edge-on. Soon some of Saturn's moon shoot past. The next sequence (00:11) features Saturn's unusually wavy F-ring that is constrained by the two shepherd moons that are also continually perturbing it. Soon much of Saturn’s extensive ring system flashes by, sometimes juxtaposed to the grandeur of the immense planet itself. Cloud patterns on Titan (00:39) and Saturn (00:41) are highlighted. Clips from flyby’s of several of Saturn’s moon are then shown, including Phoebe, Mimas, Epimetheus, and Iapetus. In other sequences, moons of Saturn appear to pass each other as they orbit Saturn. Background star fields seen by Cassini are sometimes intruded upon by bright passing moons. The robotic Cassini spacecraft has been revolutionizing humanity’s knowledge of Saturn and its moons since 2004.
