Dear Astrophysics Strategic Technology & Research Accelerator (ASTRA) community members-

As we prepare for our Ad ASTRA Community Science workshop, we are writing to share important updates regarding workshop abstract submissions, as well as ASTRA Mission Concept submissions.

Ad ASTRA Workshop

The deadline for abstract submission for the Workshop has been extended to 1 July 2026.

Submit workshop abstracts via the workshop webpage. If you have already submitted an abstract and would like to modify it based on the guidelines above, please delete your previous contribution and send another submission. Note while talks will be focused on science and technological capability themes, we encourage participants to present their mission concepts as posters, and will offer the opportunity to present as posters any abstracts for which there is insufficient room in the parallel sessions.

ASTRA Mission Concepts

The deadline for submitting ASTRA Mission Concept Documents has also been extended to 1 July 2026.

Mission Concept Document submissions should use this Word template [DOCX], and should be submitted using this submission portal [Google Form].

We look forward to your abstract submissions and to a highly collaborative and productive workshop!
