Return cruise of Hayabusa2
Orbit map of the return cruise of the Hayabusa2 spacecraft after departing from asteroid Ryugu in November 2019. -

The terminal guidance phase
The Hayabusa2 spacecraft had to perform five trajectory correction manoeuvres (TCMs) to successfully complete its mission. Whilst the capsule carrying the samples from asteroid Ryugu will land safely on Earth, Hayabusa2 will move on to chart a new course through space. -

Deployment of the Sentinel satellite
An artistic representation of the launch of the Sentinel-6 satellites into space. Orbiting at an altitude of approximately 1300 kilometres, Sentinel-6 will observe Earth’s oceans. -

Integration of Sentinel-6 Michael Freilich
Sentinel-6 Michael Freilich was integrated into its Falcon 9 launcher on 3 November 2020. On board the satellite are six scientific instruments for observing the oceans. -

Sentinel-6 satellite
The Copernicus Sentinel-6 mission consists of two identical satellites – Sentinel-6 Michael Freilich and Sentinel-6B, the second of which will be launched five years after the first. The aim of the mission is to monitor sea level rise, as well as to record sea state and ocean currents. -

Vatnajökull Glacier in Iceland
The Vatnajökull Glacier in Iceland is the largest glacier in Europe, covering an area of approximately 8400 square kilometres. Due to global warming, continental ice masses are melting, causing sea levels to rise. As a result of this and other effects, sea level is currently rising worldwide by an average of just over three millimetres per year. -

Highlands near Pyrrhae Regio on Mars
The most striking landscape feature on Mars is the almost 4000-kilometre-long Valles Marineris, just north of the equator. In the east, at Eos Chasma, the up to ten-kilometre-deep canyon system merges into a network of wide outflow channels which extend a further one-and-a-half thousand kilometres to the north and were created three to four billion years ago by episodic, catastrophic flash floods. The headwater regions of these valleys often contain ‘chaotic areas’, which were formed when subsurface ice thawed and flowed away. The resulting cavities collapsed, the energy-rich water masses took large amounts of eroded material with them, leaving behind a ‘chaotic’ pattern of mesas – the remnants of the original plateau. At Pyrrhae Regio, DLR’s HRSC instrument recorded such a chaotic area during Mars Express orbit 20,972.
