A peek at planet Earth and the moon from between the rings of Saturn

A peek at planet Earth and the moon from between the rings of Saturn

April 25, 2017 [CLICK ON IMAGE FOR HIGH RESOLUTION, Cassini Imaging Team, SSI, JPL, ESA, NASA] On April 12, as the Sun was blocked by the disk of Saturn the Cassini spacecraft camera looked toward the inner Solar System and the gas giant’s backlit rings. At the top of the mosaicked view is the A […]

Scenic vistas from . . . Mars by NASA’s Curiosity

Scenic vistas from . . . Mars by NASA’s Curiosity

September 20, 2016 It’s hard to believe that more than 4 years have passed since the Curiosity rover (a.k.a. NASA’s Mars Science Laboratory) dropped onto the broad floor of Gale crater and began its marathon exploration of Mars. Although the craft’s “primary mission” spanned only 23 months, the hope has always been that this durable, […]

Mars poses with the stars, Antares and M4

[CLICK ON IMAGE FOR HIGH RESOLUTION, Sebastian Voltmer] Wandering through this stunning field of view, Mars really is in front of these colorful cosmic clouds. The mosaic contructed from telescopic images is about 5 degrees (10 full moons) across. It captures the planet’s position on Aug. 26, over 7 light-minutes from Earth and very near […]

Cassini’s awe-inspiring view of Jupiter’s volcanic moon Io

Cassini’s awe-inspiring view of Jupiter’s volcanic moon Io

[CLICK ON IMAGE FOR HIGH RESOLUTION, Cassini Imaging Team, SSI, JPL, ESA, NASA] How big is Jupiter’s moon Io? The most volcanic body in the Solar System, Io (usually pronounced “EYE-oh”) is 3,600 kilometers in diameter, about the size of planet Earth’s single large natural satellite. Gliding past Jupiter at the turn of the millennium, […]

Cassini’s coming collision with Saturn

Cassini’s coming collision with Saturn

Aug. 1, 2016 [CLICK ON IMAGE FOR HIGH RESOLUTION, NASA/JPL-Caltech/Space Science Institute] What’s behind Saturn? The first answer is the camera itself, perched on the Cassini spacecraft currently orbiting behind the planet with the most grand ring system in our Solar System. The unusual perspective places Cassini on the far side of Saturn from the […]

‘Built like an armored tank’, Juno swoops through debris, radiation in Jupiter’s upper atmosphere

July 4, 2016 [CLICK ON IMAGE FOR HIGH RESOLUTION] NASA’s Juno spacecraft was to fire its main rocket engine late Monday to slow itself down from a speed of 150,000 mph (250,000 kph) and slip into orbit around Jupiter. With Juno on autopilot, the delicately choreographed move comes without any help from ground controllers. The […]

Juno, on July 4, will fire engine, orbit Jupiter’s poles at cloud-top level

Juno, on July 4, will fire engine, orbit Jupiter’s poles at cloud-top level

After nearly a five-year journey, Juno enjoys a perspective on Jupiter not often seen, even by spacecraft from Earth that usually swing by closer to Jupiter’s equator. Looking down toward the ruling gas giant from a distance of 10.9 million kilometers, the spacecraft’s JunoCam captured this image with Jupiter’s nightside and orbiting entourage of four […]

[CLICK ON IMAGE FOR HIGH RESOLUTION, NASA, Johns Hopkins Univ./APL, Southwest Research Institute] The night side of Pluto spans this shadowy scene. The space-based view with the Sun behind the distant world was captured by New Horizons last July. The spacecraft was at a range of over 21,000 kilometers, about 19 minutes after its closest […]

Mercury takes 7.5 hours to transit the sun

[CLICK ON IMAGE FOR HIGH RESOLUTION, Howard Brown-Greaves] On May 9, the diminutive disk of Mercury spent about seven and a half hours crossing in front of the Sun as viewed from the general vicinity of Earth. It was the second of 14 transits of the Solar System’s innermost planet in the 21st century. Captured […]

Meanwhile, on Mars it’s just another day, but where does Curiosity go for a tire change?

[CLICK ON IMAGE FOR HIGH RESOLUTION, NASA, JPL-Caltech, MSSS] Where is NASA’s rover Curiosity going on Mars? Its geographical goals are on the slopes of Mount Sharp, whose peak is seen in the background on the right. A key scientific goal, however, remains to better assess when and where conditions on Mars were once suitable […]
