DLR Magazine 161 – Light as air and versatile (12 July 2019)
German Aerospace Center (DLR)
The cover image showing cornflower-blue spheres is not drawn from the realm of botany. Is it a sponge? The airy pores suggest it. In fact, it comes from the world of high-tech materials It shows an aerogel – light, electrically conductive and thermally stable. These properties are seldom combined in one material …

Dividing night from day on Saturn's rings
In this image by the international Cassini spacecraft, Saturn's shadow is captured creeping across the rings. The bottom half of the image shows the bright rings reflecting sunlight from their icy particles, whereas the top is partially obscured in shadow…

europeanspaceagency: So that almost happened... 🛰💥🛰
⠀⠀⠀
About a week ago, data from the 18th Space Control Squadron of the US Air Force, who monitor objects orbiting in Earth’s skies, suggested a potential ‘conjunction’ at 11:02 UTC on Monday, 2 September, between our Aeolus satellite and Starlink44 – one of the first 60 satellites recently launched in SpaceX’s mega constellation, planned to be a 12 000 strong fleet by mid-2020.
⠀⠀⠀
Experts in our Space Debris Office worked to calculate the collision probability, combining information on the expected miss distance, conjunction geometry and uncertainties in orbit information.
⠀⠀⠀
As days passed, the probability of collision continued to increase, and by Wednesday 28 August the team decided to reach out to Starlink to discuss their options. Within a day, the Starlink team informed us that they had no plan to take action at this point.
⠀⠀⠀
Go to ESA Story to find out what happened in the end.
