The Director has accepted the recommendation by the Working Group on Strategic Planet Initiatives to undertake a joint JWST/HST Director’s Discretionary program to characterize the atmospheric properties of terrestrial-mass exoplanets around nearby low-mass stars.  Up to Around 500 hours of JWST time and 250 orbits of HST time will be devoted to the SMEA Rocky Worlds program starting in 2024 (Cycles 3 and 32) and likely extending through early 2027. The observations will include mid-infrared observations of multiple secondary eclipses of more than a dozen transiting exoplanets and characterization of selected host star properties at UV wavelengths. The data taken will be rapidly released to the community and STScI will produce high-level data products.

STScI as an institution must maintain the highest level of integrity in its treatment of the observations, analysis tools and high-level data products associated with the SMEA Rocky Worlds (TBC) program. STScI staff members are entitled to pursue scientific research with public JWST and HST data. However, additional considerations apply when they have access to calibration and analysis tools or to high-level data products that are being developed with HST or JWST Project funds and are not yet public. STScI Policy III-B-7 gives general guidelines on ethical use of data; this document covers issues that are specific to the SMEA programRocky Worlds program.

Structure:

The final design and implementation of the data program and the production of high-level data products will be undertaken by a Core Implementation Team (CIT), working in conjunction with the Science Advisory Committee (SAC). The overall program will be coordinated by the CIT Lead and their Deputy, who has the final authority for decisions. The CIT Lead is the Exoplanet Mission Scientist, Nestor Espinoza, and Hannah Diamond-Lowe will serve as the Deputy. They will be assisted by an observing technical lead and data technical lead. The JWST Mission Head, Tom Brown, the Interim HST Mission Head, Julia Roman-Duval, and the Multi-Mission Project Scientist, Neill Reid, will serve as a Program Advisory Council (PAC) to provide advice on high-level issues, as needed.

...

The submissions will be reviewed by the CIT Leads and the SAC, in consultation with the PAC. The deadline for submissions is August 15 (tbc). Once recruitment is complete the full membership will be published.

Data Release Schedule

SMEA has an extensive target list, with sources spanning a wide range of RA and DecThe Rocky Worlds program will have a carefully selected target list of terrestrial exoplanets orbiting M dwarf host stars. Each target will require multiple eclipse observations with JWST to search for evidence of an atmosphereatmospheres; a subset of host stars will be targeted for UV observations with HST.. Those observations will be interspersed with other GO and DD programs throughout each cycle. For each target, the eclipse data will be combined by STScI and the combined product, together with the raw data files, will be made public through MAST after all observations of that particular target are taken.  ( This is a placeholder. Feel free to adjust this proposed release strategy based on discussions with the SAC) This follows the recommendation of the Working Group to provide equitable access (see below for restrictions for CIT and SC members). HST observations of the host star stars will be non-proprietary and will be available immediately.

...

• The program implementation will be designed to achieve the science goals articulated by the Working Group on Strategic Planet Initiatives
• Any data products or analysis tools developed in the course of the SMEA Rocky Worlds program may not be used for personal research until they are made available to the general community.

...

• SAC members may not participate in submitting any publications based on Exo DD observations until that dataset has been public for at least 1 week (tbc)
• SAC members may participate in HST or JWST proposals or scientific publications based on, or supplementing, data taken for the SMEA Rocky Worlds program and/or enhanced data products associated with that program.
• There is no restriction on SAC members receiving funding for programs associated with SMEARocky Worlds.

CIT

• STScI staff working on the implementation team must clearly separate their functional work from any scientific research undertaken using these data or associated tools and data products.
• CIT members may not participate in submitting any publications based on Exo DD observations until that dataset has been public for at least 1 week (tbc)
• Members of the CIT may not serve as PIs on HST or JWST proposals that are associated directly with the SMEA Rocky Worlds programs. Those proposals include AR programs that aim to utilize SMEA Rocky Worlds data, Theory programs designed to support analysis of those data, or observing programs that aim to supplement the SMEA Rocky Worlds datasets.
• Members of the CIT may participate as co-Is in HST or JWST proposals that are associated with the SMEA Rocky Worlds programs. They must inform the CIT lead of their involvement in those proposals and they may not apply for or receive grant funding if those proposals are accepted.
