Three illustrations of what HWO may look like. From right to left, these are Engineering Architecture Concepts (EACs) 1, 2, and 3. Baffles to protect the mirror and reduce stray light are present in all designs, but are not shown for the sake of clarity. EAC-1 is a 6m, segmented, off-axis telescope. EAC-2 is the same but uses a round keystone mirror and surrounding segments. EAC-3 is an 8m on-axis telescope with round segments. Image from NASA Goddard/Conceptual Image Labs.
Habitable Worlds Observatory (HWO) will be NASA’s flagship space telescope of the 2040s, designed to search for life on other planets and to transform broad areas of astrophysics.
NASA are seeking international partners, and the UK is well-placed to lead the design and construction of its imaging camera – which is likely to produce the mission’s most visible public impact.
Early participation in the mission would return investment to UK industry, and bring generational leadership for the UK in space science, space technology, and astrophysics.
