Landing site J (pictured on the right) has been selected as Philae's primary landing site ...

The Rosetta mission's Landing Site Selection Group has selected the primary and back up landing sites for the ESA's Philae probe ahead of an attempted touchdown on 67P/Churyumov–Gerasimenko on November 11. Selecting sites J and C as the primary and back up sites respectively was no easy task, with mission operators weighing up various factors and racing against time since the spacecraft entered orbit around the comet on August 6. Prior to this, the comet had simply been too far away to characterize.  Read More

The Flyeye telescope is designed to detect asteroids that pose a potential hazard to Earth...

One aggravating property of the housefly is that swatting one is harder than it looks. That’s because flies have eyes designed for avoiding such a day-ruining event by detecting motion over a wide field of vision. Since asteroids have the potential to do to Earth what rolled newspapers do to flies, ESA is developing a telescope based on a fly’s eye as a new asteroid-hunting tool that could be the basis for a new asteroid defense network.  Read More

As the European Space Agency's (ESA) Rosetta spacecraft continues its mission by accompanying comet 67P/Churyumov-Gerasimenko (67P, for short) on its journey into the inner solar system, sensing instruments have been studying it prior to an attempted a landing by Rosetta's Philae probe. As a result, the spacecraft has collected enough information to render a map of the various areas on the surface of the comet showing that it is composed of several different regions created by a range of forces acting upon the object.  Read More

Comets are often described as "dirty snowballs" of ice and dust, which suggests something that looks like what kids throw at each other in winter. But NASA’s Alice instrument package installed aboard the ESA Rosetta probe currently orbiting comet 67P/Churyumov-Gerasimenko has sent back its first science data, which shows that the comet is about as white and fluffy as a lump of coal.  Read More

Rosetta is a mission of firsts. It is the first mission to successfully chase and rendezvous with a comet, and hopefully in November it will be the first spacecraft to make a soft landing on a celestial body that's so unlike anything we have explored before. Unfortunately, as is so often the case with firsts, there are untold risks and complications that are difficult to foresee ahead of time, but here are some of the dangers that we know about.  Read More

After you become the first spacecraft to orbit an asteroid, what do you do for an encore? For ESA’s Rosetta comet probe, the answer is to get ready for the first soft landing on a comet nucleus. Only weeks after going into orbit around comet 67P/Churyumov-Gerasimenko, the unmanned Rosetta explorer is engaged in a fast-paced reconnaissance of the comet and has identified five candidate sites for putting down the Philae lander in November.  Read More

ATV-5 docks under autonomous control (Image: ESA/NASA)

ESA’s last Automated Transfer Vehicle (ATV)-5, Georges Lemaître, has arrived at the International Space Station. In what the space agency describes as a "flawless demonstration of technology and skill," the unmanned cargo ship autonomously docked itself while supervised by mission control in Toulouse, France and by ESA astronaut Alexander Gerst and Russian cosmonaut Alexander Skvortsov inside the space station.  Read More

The list of space firsts got a little longer this week. On August 6 at 11:30 am CET, ESA's Space Operations Centre (ESOC) in Darmstadt, Germany received radio signals confirming that Rosetta had begun its approach and was going into orbit around comet 67P/Churyumov–Gerasimenko, making Rosetta the first spacecraft to go into orbit around a comet.  Read More

The International Space Station is getting a new load of groceries courtesy of ESA’s Automated Transfer Vehicle (ATV)-5 Georges Lemaître which lifted off today. The 20-tonne unmanned cargo ship was launched atop an Ariane 5 rocket at 23:44 GMT from Europe’s Spaceport in Kourou, French Guiana. The final flight of the ATV program, it carries six tonnes of supplies to the station.  Read More

Facing the alternative of a fiery death, the ESA’s Venus Express orbiter has completed a daring maneuver that extended the life of the unmanned explorer by several months. Under command from Earth, the spacecraft spent a month skimming the outer edge of the Venusian atmosphere to alter its velocity and send it into a new orbit that will keep it operating until perhaps the end of the year.  Read More
