The European Space Agency (ESA) is Europe’s gateway to space. Its mission is to shape the development of Europe’s space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world.

The red planet appears light blue in this near-infrared Hyperscout H image from ESA’s Hera spacecraft, acquired during the mission’s 12 March 2025 gravity-assist flyby of Mars, with Martian moon Deimos seen ahead of it.
The car-sized planetary defence spacecraft was approximately 1000 km from the 12.4-km-diameter Deimos moon when this hyperspectral image was acquired. Deimos orbits approximately 23 500 km from the surface of Mars and is tidally locked, so that this side of the moon is rarely seen.
In the background a variety of martian features can be observed. At the top of the image is the bright Terra Sabaea region, close to the martian equator, outlined by darker regions about it, with the 450 km-diameter Huygen crater to the bottom right of Terra Sabaea and the 460-km-diameter Schiaparelli crater to its left. To the bottom right of the Martian disc is Hellas Basin, among the largest known impact craters in the Solar System with a diameter of 2300 km and a depth of more than 7 km.
Hera’s Hyperscout H hyperspectral imager observes in a range of colours beyond the limits of the human eye, in 25 visible and near-infrared spectral bands to characterise surface materials.
