Newly Reprocessed Images of Europa Show ‘Chaos Terrain’ in Crisp Detail
The surface of Jupiter’s moon Europa features a widely varied landscape, including ridges, bands, small rounded domes and disrupted spaces that geologists call “chaos terrain.” Three newly reprocessed images, taken by NASA’s Galileo spacecraft in the late 1990s, reveal details in diverse surface features on Europa.

Parker Solar Probe Begins Longest Science Observation Campaign
On May 9, 2020, NASA’s Parker Solar Probe began its longest observation campaign to date. The spacecraft, which has already completed four progressively closer orbits around the Sun, activated its instruments at a distance of 62.5 million miles from the Sun’s surface, some 39 million miles farther from the Sun than a typical solar encounter. The four instrument suites will continue to collect data through June 28, markedly longer than the mission’s standard 11-day encounters.

Triebwerke: Treibstoff aus der Restatmosphäre
Aus einem niedrigen Orbit lassen sich interessante Erdbeobachtungen durchführen. Leider gibt es in diesen Höhen noch immer eine Restatmosphäre, die die Satelliten abbremst. Um dies zu verhindert und langlebigere Satelliten zu ermöglichen, hat man an die Universität Stuttgart ein neues Triebwerk entwickelt, das den Luftwiderstand ausgleicht und die Atmosphäre als Treibstoff nutzt.

Now, thanks to the teamwork of the Hubble Space Telescope, the Gemini Observatory, and the Juno spacecraft, scientists are able to probe deep into storm systems, investigating sources of lightning outbursts, mapping cyclonic vortices, and unravelling the nature of enigmatic features within the Great Red Spot.
