The Lynx Mission Concept Study Interim Report

Lynx is the next-generation observatory which will provide unprecedented X-ray vision into the otherwise invisible Universe to gain understanding of origins and physics of the cosmos. Lynx will see the dawn of black holes, reveal what drives galaxy formation and evolution, and unveil the energetic side of stellar evolution and stellar ecosystems. Lynx science payload will enables radical advances and leaps in capability over NASA's existing flagship Chandra and the ESA's planned Athena mission: 100-fold increase in sensitivity via coupling superb angular resolution with high throughput; 16 times larger field of view (FOV) for sub-arcsecond imaging; and 10-20 times higher spectral resolution for both point-like and extended sources. The Lynx Design Reference Mission has been designed to meet the science objectives of the future while capitalizing where appropriate on decades of experience, and especially from efficient, flight-proven approaches, design choices, and mission operations software and procedures developed for Chandra. While the science program outlined for Lynx in this report is already very broad, the observatory is designed such that there will be ample resources to execute many other programs, even those not anticipated today. Virtually all astronomers will be able to use Lynx for their own particular science.
