Rosetta: First mission to orbit and land on a comet
Rosetta is the first mission designed to orbit and land on a comet. It consists of an orbiter, carrying 11 science experiments, and a lander, called ‘Philae’, carrying 10 additional instruments, for the most detailed study of a comet ever attempted. Rosetta gets its name from the famous Rosetta stone that led to the deciphering …
SDO images ‘jack-o’-lantern’ Sun
Active regions on the sun combined to look something like a jack-o-lantern’s face on Oct. 8, 2014. The active regions appear brighter because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona. This image blends together two …
How to photograph the planets
For the last couple of issues our object spotlights have been located within our solar system. It is quite easy to see them, Jupiter and the Moon in particular, but quite difficult to image them. The term for imaging the solar system is Planetary Imaging despite the fact that both the planets, the moon and …
Cassini at Saturn: A decade exploring the ringed system
Cassini: Amazing images and even more amazing science The Cassini orbiter has been in orbit around Saturn since June 2004. Launched aboard a Titan IVB rocket from Cape Canaveral Air Force Station on October 15, 1997, it was originally dubbed Cassini-Huygens as the Huygens probe was carried along with Cassini to the Saturnian system. The …
Venus Express gets ready to take the plunge
After eight years in orbit, ESA’s Venus Express has completed routine science observations and is preparing for a daring plunge into the planet’s hostile atmosphere. Venus Express was launched on a Soyuz–Fregat from the Russian Baikonur Cosmodrome in Kazakhstan on 9 November 2005, and arrived at Venus on 11 April 2006. It has been orbiting …
‘Club sandwich’ of oceans and ice may exist within Jovian moon
The largest moon in our solar system, a companion to Jupiter named Ganymede, might have ice and oceans stacked up in several layers like a club sandwich, according to new NASA-funded research that models the moon’s makeup. Previously, the moon was thought to harbor a thick ocean sandwiched between just two layers of ice, one …
Join in the Cassini Name Game
As NASA’s Cassini mission approaches its 10th anniversary at Saturn, its team members back here on Earth are already looking ahead to an upcoming phase. Starting in late 2016, the Cassini spacecraft will repeatedly climb high above Saturn’s north pole, flying just outside its narrow F ring. Cassini will probe the water-rich plume of the …
Jupiter: The Gas Giant
Of all the planets that orbit around our Sun there are two that are easily visible and are fascinating objects to view. These are, of course, Saturn and Jupiter. Of these Jupiter is prominent in our night skies at the moment. At magnitude -2.06 it is the third brightest thing in the sky after the …
Stephen Colbert presents honor from NASA to Voyager scientist
As if NASA’s Voyager mission didn’t have enough firsts in its 36-year journey, what with sending the first spacecraft to Uranus, Neptune and, most recently, interstellar space! Now, it has another first back here on Earth: on the December 3, 2013 episode of the Colbert Report, host Stephen Colbert floated across the stage in a …
Comets are unpredictable beasts
The media was full of talk of comets with the inaugural visit of Comet ISON C/2012 S1. It was pre-hyped as being “The Comet of the Century”, being visible in daylight etc, etc. The reality of the matter is that comets are strange beasts and are rarely predictable unless they have been round a few …
