Advanced Technologies and Instrumentation for the Astronomical Sciences

Deadline: October 1st - November 17th, 2025

The Advanced Technologies and Instrumentation for the Astronomical Sciences (ATI) program provides individual investigator and collaborative research grants for the development of new technologies and instrumentation for use in ground-based astronomy and astrophysics.

NSF 22-627 Solicitation about Advanced Technologies and Instrumentation for the Astronomical Sciences
The heart of Hitomi's Soft X-ray Spectrometer is the microcalorimeter array at center. The five-millimeter square forms a 36-pixel array. Each pixel is 0.824 millimeter on a side, or about the width of the ball in a ballpoint pen. The detector's field of view is approximately three arcminutes, or one-tenth the apparent diameter of the full moon. Credit: NASA's Goddard Space Flight Center

The program supports achieving the science objectives of the Division of Astronomical Sciences. The development of innovative, potentially transformative, technologies and instruments are sought, even at high technical risk. Supported categories include (but are not limited to): advanced technology development, concept feasibility studies, and specialized instrumentation to enable new observations that are difficult or impossible to obtain with existing means. Proposals may include hardware and/or software development and/or analysis to enable new types of astronomical observations. Access to the ATI supported technology and instrumentation development efforts by the US astronomical community is viewed as an important metric of success. An annual Principal Investigators meeting is planned to disseminate information between the funded research efforts.

An illustration of Sun-like star HD 181327 and its surrounding debris disk. The star is at top right. It is surrounded by a far larger debris disk that forms an incomplete ellpitical path and is cut off at right. There’s a huge cavity between the star and the disk. The debris disk is shown in shades of light gray. Toward the top and left, there are finer, more discrete points in a range of sizes. The disk appears hazier and smokier at the bottom. The star is bright white at center, with a hazy blue region around it. The background of space is black. The label Artist's Concept appears at lower left.
