NASA has moved the Advanced X-ray Imaging Satellite (AXIS) mission, co-led by McGill University Professor Daryl Haggard, into the final selection phase of its $1 billion space probe competition.

AXIS is one of two concepts chosen for further evaluation under NASA's Probe Explorers program, which emphasizes X-ray and far-infrared astronomy.

The mission aims to explore the origins of primordial black holes, their formation, and their impact on galaxy evolution, while also investigating stellar collapses and mergers.

AXIS is expected to significantly surpass the sensitivity of the Chandra X-ray Observatory, offering unprecedented insights into high-energy processes and galaxy formation.

The mission team will receive $5 million over the next year to refine its proposal, with Haggard's expertise in black holes being essential for achieving its scientific goals.

Haggard will lead the AXIS Time-Domain and Multi-Messenger Science Working Group, which will focus on detecting electromagnetic counterparts of significant astrophysical events.

Professor Haggard emphasizes that the mission presents a unique opportunity to tackle fundamental astrophysical questions.

NASA plans to finalize its mission selection in 2026, with a potential launch of AXIS anticipated in 2032 if it is selected.
