Event description

Description

Laurence O'Rourke from the European Space Agency will give a free public talk on his work with the Rosetta mission. This event is part of the Irish National Astronomy Meeting 2017 - Organised by the Astronomical Science Group of Ireland (www.astrophysics.ie)

His talk will describe the engineering challenges and the dangers of the mission with a focus on the two landings that were performed on the comet – the first being the Philae lander in November 2014 and the second the Rosetta spacecraft itself when it landed to end the mission on 30th September last year.
While summarising what is now known about the comet, the engineering & scientific techniques used by the team in taking measurements at the comet will be described including how the landing site of Philae was identified. The presentation will cover the Philae landing & its findings and in particular will highlight the work done by the Rosetta team in locating Philae on the surface of the comet nearly 2 years after it landed/bounced and was lost in a rocky shadowy region. The presentation will then cover the dangers faced by the spacecraft when flying around the comet as it got closer to the sun before focussing in on the second and final landing. At this point, the steps required to land the mother craft Rosetta on the comet including how its the final resting site was chosen will be presented as well as providing a run through the final weeks & days & minutes leading to that event.
