Nominations for EnVision Science Study Team Due April 11

The Planetary Science Division of NASA's Science Mission Directorate invites nominations for service on the European Space Agency (ESA) EnVision Science Study Team (SST) starting in June 2019 with an estimated duration of two years. 

EnVision is one of three mission studies in competition for ESA's Medium Class 5 (M5) selection with an expected launch readiness date of 2032. EnVision aims to improve understanding of Venus' geologic history and why Earth and Venus have evolved to be so differently. The the prime mission instrument is a high spatial resolution synthetic aperture radar (SAR), and baseline mission payload also includes three infrared and ultraviolet spectrometers, a subsurface sounding radar, and a radio-science package.

U.S. citizens may submit self-nominations for consideration to be part of the EnVision SST. This nominating process is intended to be independent of the proposing EnVision team. As such, individuals who have been part of the proposed EnVision team are excluded from consideration. NASA and ESA will jointly select at least two SST science members. NASA is committed to selecting members to serve on this SST committee based on their individual expertise, knowledge, experience, current/past contributions to the relevant subject area and overall diversity of the committee. NASA is committed to ensuring that the membership of the EnVision SST draws from the diversity of the entire U.S. Venus science community. NASA will cover travel and per diem expenses for all member appointments and some labor as needed to fulfill this task.

The deadline for NASA receipt of all public nominations is no later than April 11, 2019.

To be considered by NASA, self-nomination packages from interested U.S. citizens must be sent to NASA as an email. The following information is required to be included as part of each nomination package: (1) A cover email to with subject line, "EnVision SST Nomination"; (2) a professional resume (one-page maximum, included as an attachment); and, (3) a professional biography (three-page maximum; included as an attachment) that includes experience and contributions relevant to Venus science. All public nomination or self-nomination packages must be submitted electronically via email to NASA at; hard-copy nominations will not be accepted. Note: nomination packages that do not include the three (3) mandatory elements listed above will not receive further consideration by NASA.
