Robotic missions exploring our solar system have wowed the world with their discoveries and especially the images they return. But even the most sophisticated spacecraft is useless until the science and engineering it gathers makes it back to Earth. NASA’s one of a kind collection of massive dishes around the world makes that possible. The …

1) As the World Turns: The DSN is Earth’s only global spacecraft communication network The Deep Space Network has three facilities – at Goldstone, Calif.; near Madrid, Spain; and Canberra, Australia, all with multiple parabolic dish antennas, including one dish each that is 230 feet (70 meters) across. Located about 120 degrees apart around Earth, the …

Comet 67P/Churyumov-Gerasimenko (I’ll call it Comet 67P) has been minding its own business for billions of years as it quietly looped around the Sun every 6.5 years. Discovered in 1969 by astronomers Klim Ivanovych Churyumov and Svetlana Ivanovna Gerasimenko, it spins around on its own axis every 12 hours and is about 2 miles across. …

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 …

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 …

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 …
