The N3 Activity aimed to develop synergies between space missions and telescope observations from the ground or from Earth orbit, maximising the scientific return on both sides.
With a complete tool-box of ground-based observatories, Earth-orbiting telescopes and space missions that take in-situ measurements, astronomers are now able to observe at wavelengths ranging across the electromagnetic spectrum, and use multiple observatories simultaneously. By applying different ground-based techniques and taking measurements at wavelengths outside the capabilities of the spacecraft, scientists on Earth can complement the data collected by the spacecraft and cross-validate the spacecraft’s observations. There is also a large, active and highly-skilled community of amateur astronomers watching various solar system
objects regularly, that obtain excellent images to complement data from observatories.
N3 supported two types of coordinated observations:
These activities encouraged an environment for the efficient exchange of ideas, experiences, and results among the various research teams, developing established co-operations and stimulating new links. A coordination working group defined a global strategy for observations, identifying observational targets, discussing and initiating particular observational campaigns during workshops and teleconferences.
The N3 strategic workshops proved to be very popular and helped to consolidate and link the European planetary science. Discussions and co-ordination efforts in the N3 workshops were put into practice through the N3 observation campaigns. Five campaigns were organised during the project, including:
These observation campaigns generated valuable output for the continuation of activity in respective fields of planetary science and a total of 25 papers were published in peer-reviewed scientific journals over the duration of the EuroPlaNet project.
N3’s success in building links to the amateur community in key research areas, for example meteors or stellar occultation, has been a key achievement for EuroPlaNet. The incorporation of amateur observers broadens the observational basis and constitutes a multiplication factor for observations.
