ESA's Hera asteroid mission during ground testing at the ESTEC Test Centre in the Netherlands in 2024. Note its 1.13 m diameter Large Gain Antenna, its main means of communicating with Earth. To the left is its 'Asteroid Deck' where its instruments are hosted, including its two cylindrically-shaped Asteroid Framing Cameras to the rear and its two CubeSats seen partly deployed. The spacecraft is seen here inside the Maxwell Test Camera for electromagnetic compatibility testing.
