The Incredible Adventures of the Hera mission – Tales of Terrific Technology

Meet Hera, our very own asteroid detective. Together with two CubeSats – Milani the rock decoder and Juventas the radar visionary – Hera is off on an adventure to explore Didymos, a double asteroid system that is typical of the thousands that pose an impact risk to planet Earth. Suitable for kids and adults alike, this […]

After DART comes Hera

After DART comes Hera

The night of 26 September 2022 made space history – as the moment when NASA’s DART spacecraft impacted the Dimorphos asteroid in an attempt to divert its course – humankind’s first planetary defense test. Next, in 2024, ESA launches its Hera spacecraft to investigate the post-impact asteroid. In fact, Hera is not one spacecraft but […]

After NASA’s asteroid impact, ESA’s Hera comes next

After NASA’s asteroid impact, ESA’s Hera comes next

This month NASA’s DART spacecraft will collide with the smaller of the two Didymos asteroids in deep space, attempting to shift its orbit in what will be humankind’s first test of the ‘kinetic impactor’ planetary defence technique. Meanwhile, down on the ground, ESA’s follow-on mission to Didymos has reached its own crucial milestone. The main […]

Hera Asteroid Mission’s First Step

Hera asteroid mission’s first step

A key element of ESA’s Hera mission for planetary defence has left the facilities of its manufacturer OHB in Bremen – a major step in preparation for its eventual odyssey to the Didymos asteroid system. The mission’s Propulsion Module flight model, seen here, has been delivered to Avio, southeast of Rome, where propellant tanks, thrusters and associated pipes and valves […]

Meet the Backbone of the Hera asteroid mission

Backbone of Hera asteroid mission

Adapted from ESA Agency page. In a Swiss cleanroom, this historic object has been taking shape. Made of carbon fiber reinforced polymer, this is the central core of ESA’s Hera asteroid mission for planetary defense. NASA’s DART spacecraft is currently on its way to the Didymos asteroid pair in deep space, to test the kinetic […]
