In 2014 we presented a concept for an Evolvable Space Telescope (EST) that was
assembled on orbit in 3 stages, growing from a 4x12 meter telescope in Stage 1, to a 12 …

Astronomical flagship missions after JWST will require affordable space telescopes and
science instruments. Innovative spacecraft-electro-opto-mechanical system architectures …

Over the past few years, we have developed a concept for an evolvable space telescope
(EST) that is assembled on orbit in three stages, growing from a 4× 12-m telescope in Stage …

• Larger than 12 meter aperture telescopes are needed to perform the next generation
science missions 1• Current concepts for single launch observatories are limited to 9.2 meter …

Previous papers have described our concept for a large telescope that would be assembled
in space in several stages (in different configurations) over a period of fifteen to 20 years …

The concept for EST presented in past SPIE forums will benefit significantly from the current
efforts of DARPA, NASA and several commercial organizations to develop an in-space …

The Advanced Technology Large-Aperture Space Telescope (ATLAST) is a set of mission
concepts for the next generation of UVOIR space observatory with a primary aperture …

We describe a paradigm shift for astronomical observatories that would replace circular
apertures with rotating synthetic apertures. Rotating Synthetic Aperture (RSA) observatories …

We present results of a study of a deployable version of the Advanced Technology Large-
Aperture Space Telescope (ATLAST), designed to operate in a Sun-Earth L2 orbit. The …

As with ground based observatories, future space observatories will require increasingly
large apertures in order to address the latest questions concerning the nature of our …
