Transient Astronomy Proposed a Constellation Instead of One Flagship
The Hydra concept distributes responsive multiwavelength follow-up across smaller spacecraft for a follow-up-limited sky.
Summary
The Hydra concept distributes responsive multiwavelength follow-up across smaller spacecraft for a follow-up-limited sky.
Hydra is a white-paper concept for a proliferated space architecture aimed at time-domain and multi-messenger astronomy. Rather than depending on one large observatory for every rapid follow-up, it would distribute responsive multiwavelength capabilities across a constellation. The motivation is an era in which surveys find more short-lived events than existing space assets can promptly observe. Hydra is a mission architecture proposal, not an approved program, deployed constellation or demonstrated performance result.
