ESA approves Hera mission to study DART impact for planetary defense
7 day briefing • 2019-11-28 - 2019-12-04 (6 years ago) • frozen
This week, the European Space Agency (ESA) formally approved the Hera mission to visit the Didymos binary asteroid system. Hera is a key component of international planetary defense efforts, as it will analyze the aftermath of NASA's DART (Double Asteroid Redirection Test) mission. The DART mission, scheduled for 2022, will intentionally impact the moonlet of Didymos to test asteroid deflection technology.
Hera, launching in 2024, will then conduct a detailed survey of the impact site, measuring the crater and orbital deviation. This approval marks a significant step forward in humanity's ability to protect Earth from potential asteroid impacts. The mission involves collaboration between ESA, NASA, and other partners, demonstrating the growing importance of space-based defense initiatives.
The decision was made at the Space19+ ministerial meeting, where ESA member states also approved funding for other programs. Hera's detailed data will refine models of asteroid deflection and help validate kinetic impactor techniques as a viable defense strategy.
