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 …
Exploring the surface of a comet
On August 6, 2014 after a decade-long journey chasing its target, ESA’s Rosetta has today become the first spacecraft to rendezvous with a comet, opening a new chapter in Solar System exploration. Comet 67P/Churyumov–Gerasimenko and Rosetta now lie 405 million kilometers from Earth, about half way between the orbits of Jupiter and Mars, rushing towards …
Spaceport America: A convergence of ideas and events
The rumble of a rocket engine and then a distant sonic boom break the breezy silence of a remote desert plain. Another unmanned commercial rocket has been launched from Spaceport America. Soon, perhaps in a few months, Virgin Galactic will begin space tourism flights with a futuristic spacecraft air launched from a mothership using Spaceport …
