During the Mercury transit on November the 11th, 2019, IAS researchers and the ALCOR astronomy club will organize an afternoon with observations of the Sun, conferences, and workshops. This event will take place on the University campus at the new physics teaching building, "hbar" (building 625).
« Hello, JUICE ? - Hi MAJIS, nice to meet you ! Let’s have fun ! ;-) »: This is the first message that ADS (Airbus Defense and Space), prime contractor of the ESA JUICE satellite, sent to the MAJIS (Moons And Jupiter Imaging Spectrometer) team, hence validating the EM (Engineering Model) stage of the MAJIS spacecraft.
The “Planetary and Solar System Sciences” Division of EGU (European Geophysical Union) has awarded to John Carter, associate astronomer at IAS, its 2019 “Oustanding Early Career Scientist” medal for his discoveries on the composition of the martian surface, in particular hydrated minerals and their implications on the climate history of Mars, and for his contributions to the interpretation of orbital spectral data.
This critical operation, performed on February 22, 2019, constituted the most complex and risky part of the ISAS/JAXA Japanese mission: it required to bring the entire spacecraft in contact with the surface of Ryugu, entirely covered with boulders of all sizes. Its success demonstrates and translates an extraordinary and unique control of space operations by ISAS/JAXA engineers. A second sample collection could be performed in a few months, prior to the return to Earth: Hayabusa2 should leave Ryugu in December 2019, to land on Earth a year later. Our laboratories should thus get in 2021 samples collected at the very surface of one of the most ancient solar system objects, rich in particular of organics which might have played a major role in the evolution towards life on Earth.
The launch of the BepiColombo spacecraft (ESA/JAXA) took place on October 19, 2018 at 10:45 pm from the Ariane 5 site in Kourou. BepiColombo has successfully started its long journey to the planet Mercury, with onboard SIMBIO-SYS, a complex of 3 instruments that will map the surface of the planet with unprecedented spatial resolution and spatial coverage. IAS is co-PI of this instrument through the supply of the main electronics and the implementation of the calibration of the integrated instrument.
