The next planning cycle of the ESA Science Programme, Voyage 2050, is now underway.

In keeping with the bottom-up, peer-reviewed nature of the Science Programme, the definition of the next plan relies on open community input and on broad peer review.

The community input will be gathered through the Call for White Papers, while the peer review of this input will take place through a two-tiered committee structure, with a Senior Committee of 13 European scientists supported by a number of Topical Teams.

Scientists interested in participating in peer review process are invited to respond to the Call for Membership of the Topical Teams.
