Science programming of NASA’s Webb telescope

On July 12th, on the way to the release of the first full-color images and spectroscopic data from Webb, the Webb team is in the final stages of launching its scientific tools. The first two tool modes, NIRCam images and NIRISS images, have been declared ready for science; see the “Where is Webb” page for the band’s journey through 15 other instrument modes.

Once the launch is complete, the fun — and discoveries — will begin: the implementation of hundreds of peer-to-peer science programs selected by Webb for the first year. The area of ​​the sky that the web can see at any given time is called the field of view. Deciding on which days to do the observation is a complicated process designed to optimize the effectiveness of the observation and manage the resources of the observatory. We asked Christine Chen, head of the space policy team at the Space Telescope Science Institute (STScI), to tell us how Webb’s schedule is wrapped up.

“Webb will soon be up and running when Webb’s time is focused on scientific observations,” said Christine Chen, head of Webb’s science policy team at the Space Telescope Science Institute in Baltimore, Maryland.

“The first year of Webb’s observations (Cycle 1) has already been selected. There are three types of scientific programs planned: General Observer (GO), Time-Guaranteed Observer (GTO) and Early Discretion Science (DD-ERS). GO and DD- ERS programs bring together scientists from around the world, whose programs were selected through a double anonymous peer review process. The GTO program is led by scientists who have made important contributions to the development of the observatory.

“All observations in approved Cycle 1 programs are available for early programming. However, DD-ERS observations have been prioritized for the first five months because DD-ERS programs are designed to support the scientific community. Understand Webb’s performance as soon as possible for typical scientific observations .

“Webb’s Long-Term Planning Team (LRPG) has created a 12-month Observation Plan, including all approved observations, with the goal of creating the most effective plan. This subscription will allow for a smooth transition between cycles, as well as a repository of flight-ready observations that can be moved earlier if a window is opened, which is currently not fully complied with before the start of Cycle 1. it allows programmers to use the late-breaking Opportunity Objectives (ToOs) and Director’s Discretionary (DD) programs, which are typically “unplanned” for events such as stellar comets, gravitational wave sources, and supernovae.

“In normal operations, the Short-Term Programming Group (STSG) will create specific weekly calendars for the observatory next week. Accumulating time on wheels, etc. At the beginning of each week, the Flight Operations Team will link the Weekly Short-Term Schedule to Webb.At the end of each week, the LRPG will update the Observation Plan to reflect on the actual programs that have been implemented and identify next week’s priorities. and STSG work together synergistically throughout the observation cycle to maximize the scientific performance of the observatory. ”
