PARIS, 25 August 2014 (ESA PR) — Using detailed information collected by ESA’s Rosetta spacecraft during its first two weeks at Comet 67P/Churyumov-Gerasimenko, five locations have been identified as candidate sites to set down the Philae lander in November – the first time a landing on a comet has ever been attempted.

Before arrival, Comet 67P/Churyumov-Gerasimenko had never been seen close up and so the race to find a suitable landing site for the 100 kg lander could only begin when Rosetta rendezvoused with the comet on 6 August.

Arianespace and ESA have issued an update on the launch anomaly that stranded two Galileo navigation satellites in the wrong orbits. The statement confirms that investigators are focused on an apparent problem with the Fregat upper stage of the Russian Soyuz ST launch vehicle.

The update provides no information about the fate of the satellites other than to say they are healthy and communicating with the ground. The European Commission has not issued an update since Friday, when it celebrated what it thought was a fully successful launch.

After much celebratory rhetoric on Friday over the launch of two Galileo navigation satellites from Kourou, European officials realized the spacecraft were placed in the wrong orbits.

Arianespace, which managed the launch of the Russian Soyuz booster, made a terse announcement:

Complementary observations gathered after separation of the Galileo FOC M1 satellites on Soyuz Flight VS09 have highlighted a discrepancy between targeted and reached orbit.

Investigations are underway. More information will be provided after a first flight data analysis to be completed on August 23, 2014.

WASHINGTON (NASA PR) – After a decade-long journey chasing its target, the European Space Agency’s Rosetta, carrying three NASA instruments, became the first spacecraft to rendezvous with a comet. The last of a series of 10 rendezvous maneuvers that began in May, to adjust Rosetta’s speed and trajectory to gradually match those of comet 67P/Churyumov-Gerasimenko, occurred on Aug. 6, 2014.

“After 10 years, five months and four days travelling towards our destination, looping around the sun five times and clocking up 6.4 billion kilometers, we are delighted to announce finally we are here,” said Jean-Jacques Dordain, ESA’s director General.

PARIS, 5 August 2014 (ESA PR) – 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 kilometres from Earth, about half way between the orbits of Jupiter and Mars, rushing towards the inner Solar System at nearly 55 000 kilometres per hour.

PARIS (ESA PR) — As ESA’s remaining supply ferry to the International Space Station burns up in the atmosphere, its final moments as its hull disintegrates will be recorded from the inside by a unique infrared camera.

An ESA-led team designed and developed the Automated Transfer Vehicle (ATV) Break-Up Camera in just nine months in order to make it on board in time.

PARIS (ESA PR) — All eyes are on ESA’s spaceplane to showcase reentry technologies after its unconventional launch on a Vega rocket this November.

Instead of heading north into a polar orbit – as on previous flights – Vega will head eastwards to release the spaceplane into a suborbital path reaching all the way to the Pacific Ocean.

Space News reports that the future of the Ariane 6 launch vehicle remains uncertain after a meeting in Geneva on Tuesday:

The ministers from France, Germany, Italy, Belgium and Switzerland took no formal decision but agreed to reassess the situation in September after further study of the costs associated with the two designs.
