[15] Contact was briefly and intermittently reestablished several months later at various times between 13 June and 9 July, before contact was lost once again. On 12 November, a lander named Philae was deployed and made the first soft landing on a comet. [182], To promote the spacecraft's arrival at comet 67P/Churyumov–Gerasimenko and the landing of Philae in 2014, a short film was produced by the European Space Agency with Polish visual effects production company Platige Image. Although three scripts are shown (Egyptian Hieroglyphs, Egyptian Demotic and Greek) just two languages are represented. 16 March – Observation of the dust tail of asteroid, 10 July – Flew by and photographed the asteroid. The lander module of Rosetta was Philae. Rosetta is the most complex space mission ever flown by Europe. Here are five strange facts about Rosetta's target, Comet 67P/C-G: It's going to be harpooned . The mission was originally set for a rendezvous with Comet 46 P/Wirtanen. Two solar panels, with a combined area of 64 m², each stretch out to 14 m in length.
[103][104], As the orbit of comet 67P took it farther from the Sun, the amount of sunlight reaching Rosetta's solar panels decreased. The craft was therefore put into standby mode, with no possibility to communicate, flying on batteries that were originally not designed for this task. [108][109][111] The spacecraft's estimated speed at the time of impact was 3.2 km/h (2.0 mph; 89 cm/s),[18] and its touchdown location, named Sais by the operations team after the Rosetta Stone's original temple home, is believed to be only 40 m (130 ft) off-target. The great significance of the Stone is that it provided the key to deciphering Egyptian hieroglyphs.

The mission was launched on 2 March 2004, on a 10-year journey towards comet 67P/Churyumov-Gerasimenko. Primary mission objectives: Rosetta also dips in and out of the main asteroid belt between Mars and Jupiter. The International Rosetta Mission was approved in November 1993 by ESA's Science Programme Committee as the Planetary Cornerstone Mission in ESA's long-term space science programme. [185][186] Ambition was premiered at the British Film Institute's Sci-Fi: Days of Fear and Wonder film festival in London on 24 October 2014, three weeks before the landing of Philae on 67P/Churyumov–Gerasimenko.

Relubrication was also performed on this RWA, but methods were found to temporarily increase its operating temperature to better improve the transfer of oil from its reservoir. Now, another ESA spacecraft, named Rosetta, is on its way to a comet. [107], On 28 September 2017, a previously unrecovered image taken by the spacecraft was reported. In addition, the reaction wheel's speed range was decreased to limit lifetime accumulated rotations. [31] Lutetia was also observed by the visible–near-infrared imaging spectrometer VIRTIS, and measurements of the magnetic field and plasma environment were taken as well. The Rosetta mission is made up of two parts: the Rosetta space probe and the Philae lander. Along with Philae, its lander module, Rosetta performed a detailed study of comet 67P/Churyumov–Gerasimenko (67P). [79] Three RWAs were kept operational, while one of the malfunctioning RWAs was held in reserve. The Giotto spacecraft is also depicted as the duo's grandfather, whereas others in the Halley Armada as well as NASA's Deep Impact and Stardust spacecraft are depicted as their cousins. The measurements to be made to achieve this are: Artist's impression of Rosetta and Philae at the comet. Enter deep space hibernation: 8 June 2011 [67] This Mars manoeuvre was therefore nicknamed "The Billion Euro Gamble". This is another outstanding performance by flight dynamics.

Comets are thought to have delivered a vast quantity of water to Earth, and they may have also seeded Earth with organic molecules. To rendezvous with Comet 67P/Churyumov-Gerasimenko and study the nucleus of the comet and its environment for nearly two years, and land a probe on its surface. This animation tracks Rosetta's journey through the Solar System, using gravity slingshots from Earth and Mars to reach its final destination: comet 67P/Churyumov-Gerasimenko. Rosetta fact sheet ESA FACT SHEET Posted: February 24, 2004. Journey milestones:

Unlike the Deep Impact probe, which by design struck comet Tempel 1's nucleus on 4 July 2005, Philae is not an impactor. [79], In August 2014, Rosetta rendezvoused with the comet 67P/Churyumov–Gerasimenko (67P) and commenced a series of manoeuvres that took it on two successive triangular paths, averaging 100 and 50 kilometres (62 and 31 mi) from the nucleus, whose segments are hyperbolic escape trajectories alternating with thruster burns.

Maximum relative speed between the two objects during the flyby was 8.6 km/s (19,000 mph; 31,000 km/h).

[110][112] Rosetta's computer included commands to send it into safe mode upon detecting that it had hit the comet's surface, turning off its radio transmitter and rendering it inert in accordance with International Telecommunication Union rules. This is the end of the Rosetta mission. 1st Earth gravity assist: 4 March 2005 Rosetta was a simple space probe aimed at a comet orbiter/lander type of mission. Two solar panels, 32 square meters each, extend outward from opposite sides of the box, spanning 32 m tip-to-tip. Launched on 2 March 2004, Rosetta will take 10 years to reach comet Churyumov-Gerasimenko.

[88] Analysis of telemetry indicated that the surface at the initial touchdown site is relatively soft, covered with a layer of granular material about 0.82 feet (0.25 meters) deep,[89] and that the harpoons had not fired upon landing.

After the success of the series, however, the ESA commissioned the studio to continue producing new episodes in the series throughout the course of the mission. [108][109][107] Its trajectory targeted a site in the Ma'at region near an area of dust- and gas-producing active pits. - Rosetta’s original target was comet 46P/Wirtanen, but after postponement of the initial launch a new target was set: Comet 67P/Churyumov-Gerasimenko. The series depicts various stages in the Rosetta mission, involving the personified Rosetta and Philae on "a classic road trip story into the depths of our universe", complemented with various visual gags presented in an educational context.
[176] Produced by animation studio Design & Data GmbH, the series was initially conceived by the ESA as a four-part fantasy-like series with a Sleeping Beauty theme that promoted community involvement in Rosetta's wake up from hibernation in January 2014. It gets its power from two huge solar panels, each 14 metres long. Titled Ambition, the film, shot in Iceland, stars Irish actor Aidan Gillen, known for his roles in Game of Thrones and The Wire, and Irish actress Aisling Franciosi, also of Game of Thrones fame, and was directed by Oscar-nominated Polish director Tomasz Bagiński. [56], Rosetta was built in a clean room according to COSPAR rules, but "sterilisation [was] generally not crucial since comets are usually regarded as objects where you can find prebiotic molecules, that is, molecules that are precursors of life, but not living microorganisms", according to Gerhard Schwehm, Rosetta's project scientist. This made it unable to adequately collect solar power, and it lost contact with Rosetta when its batteries ran out after two days, well before much of the planned science objectives could be attempted. [31][77], After leaving its hibernation mode in January 2014 and getting closer to the comet, Rosetta began a series of eight burns in May 2014. While it would have been possible to put Rosetta into a second hibernation phase during the comet's aphelion, there was no assurance that enough power would be available to run the spacecraft's heaters to keep it from freezing. [21][19] After closing to within about 30 km (19 mi) from the comet on 10 September, the spacecraft entered actual orbit about it.
