The ESA comet chaser

Post by brian livesey »

The European Space Agency has given the go-ahead for the construction of a new spacecraft dubbed "the comet chaser", planned to launch in 2028. The aim of the project is to approach comets and map them in 3D for the first time.
The spacecraft will have two robotic probes onboard to map a still unidentified comet, probably from the Oort Cloud. This is a cloud of ice and comets at a great distance from the Sun that encircles the Solar System.
The comet chaser is the first of the ESA's "fast missions", with the weight of each one restricted to less than 1,000kg. The spacecraft will be constructed by aerospace company Thales Alenia.

After a successful awakening Rosetta will head for the Churyumov-Gerasimenko comet, which is its main target. It is expected that the device will approach it in August and enter orbit around the comet, and then, in November, a small research module "Philae" will be launched from the probe into the celestial body, which will determine the parameters of the nucleus and its chemical composition.

Why can't I find latest news about this project? The latest reference I found is dated by 2020. Does anyone know more up-to-date news?

Philae landed in 2014.

Yes, but what about results of it? Any analyzes, photos, measurements?

Rosetta as every great mission brings data and experience.

https://www.esa.int/Science_Exploration ... t_to_comet

Some of the most unexpected and important results are linked to the gases streaming from the comet’s nucleus, including the discovery of molecular oxygen and nitrogen, and water with a different ‘flavour’ to that in Earth’s oceans.

Overall, the results delivered by Rosetta so far paint comets as ancient leftovers of early Solar System formation, rather than fragments of collisions between larger bodies later on, giving an unparalleled insight into what the building blocks of the planets may have looked like 4.6 billion years ago.

Comets are time capsules containing primitive material left over from the epoch when the Sun and its planets formed. By studying the gas, dust and structure of the nucleus and organic materials associated with the comet, via both remote and in situ observations, the Rosetta mission is a key to unlocking the history and evolution of our Solar System.

“It’s a bittersweet ending, but in the end the mechanics of the Solar System were simply against us: Rosetta’s destiny was set a long time ago. But its superb achievements will now remain for posterity and be used by the next generation of young scientists and engineers around the world.”
