Reconstruction of second surface contact by Rosetta’s Philae lander during unplanned ‘hopping’ in November 2014 before its final ‘touchdown’.
The probe, rotating like a windmill, scraped a furrow in a highly porous, dark rocky area made of ice and dust on comet 67P, exposing 4.5-billion-year-old ice.
The ice has very weak internal cohesion and a consistency that is fluffier than cappuccino froth.
COLOGNE, Germany (DLR PR) — After years of detective work, scientists working on the European Space Agency (ESA) Rosetta mission have now been able to locate where the Philae lander made its second and penultimate contact with the surface of Comet 67P/Churyumov-Gerasimenko on 12 November 2014, before finally coming to a halt 30 metres away. This landing was monitored from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Philae Control Center.
PARIS (ESA PR) — Scientists analysing the treasure trove of images taken by ESA’s Rosetta mission have turned up more evidence for curious bouncing boulders and dramatic cliff collapses.
Rosetta operated at Comet 67P/Churyumov-Gerasimenko between August 2014
and September 2016, collecting data on the comet’s dust, gas and plasma
environment, its surface characteristics and its interior structure.
MARSEILLE, France (ESA PR) — Feeling stressed? You’re not alone. ESA’s Rosetta mission has revealed that geological stress arising from the shape of Comet 67P/Churyumov–Gerasimenko has been a key process in sculpting the comet’s surface and interior following its formation.
Small, icy comets with two distinct lobes seem to be commonplace in the Solar System, with one possible mode of formation a slow collision of two primordial objects in the early stages of formation some 4.5 billion years ago. A new study using data collected by Rosetta during its two years at Comet 67P/C-G has illuminated the mechanisms that contributed to shaping the comet over the following billions of years.
The entire history of human existence is a tiny blip in our solar system’s 4.5-billion-year history. No one was around to see planets forming and undergoing dramatic changes before settling in their present configuration. In order to understand what came before us — before life on Earth and before Earth itself — scientists need to hunt for clues to that mysterious distant past.
PARIS (ESA PR) — Rosetta’s lander Philae will target Site J, an intriguing region on Comet 67P/Churyumov–Gerasimenko that offers unique scientific potential, with hints of activity nearby, and minimum risk to the lander compared to the other candidate sites.
Site J is on the ‘head’ of the comet, an irregular shaped world that is just over 4 km across at its widest point. The decision to select Site J as the primary site was unanimous. The backup, Site C, is located on the ‘body’ of the comet.
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.
