Playing with fire – safely of course. The Combustion Integrated Rack (CIR) in @NASA's Destiny lab helps researchers investigate how fuels burn in space to improve rockets, satellites, and fuel efficiency on Earth. @ISS_Research #Horizons pic.twitter.com/lkjqw9UIzQ

Mit dem Feuer spielen - natĂĽrlich sicher. Mit dem Combustion Integrated Rack (CIR) im Destiny-Labor der @NASA untersuchen wir, wie Kraftstoffe im Weltraum verbrennen, um Raketen, Satelliten und Kraftstoffeffizienz auf der Erde zu verbessern. @ISS_Research #Horizons pic.twitter.com/t6Z6dSAB3S

These three people are the only humans living in space right now. During his first week in command of the International @Space_Station, @Astro_Alex installed a new life-support system and checked his muscle tone #Horizons #LiveBetter

These big holes influenced human history quite a bit. One of them is the Chuquicamata copper mine in the Atacama Desert, among the biggest on that planet down there. #Horizons pic.twitter.com/dd21Nu8fit

Diese riesigen Löcher haben die menschliche Geschichte wesentlich beeinflusst. Eines der beiden ist die Chuquicamata-Kupfermine in der Atacama-Wüste, eine der größten auf dem Planeten. #Horizons pic.twitter.com/Bm2yafulT8

Here you can see that the Gulf of Aqaba was actually generated by a tectonic fracture zone. It extends north into the Dead Sea, and beyond along the Jordan river through the Sea of Galilee. #Horizons pic.twitter.com/5yurTYl8rD

Auf diesem Bild kann man erkennen, dass der Golf von Akaba durch eine tektonische Störungszone erzeugt wurde. Diese reicht weit nach Norden, bis durchs Tote Meer hindurch und weiter entlang des Jordans durch den See Genezareth. #Horizons pic.twitter.com/kYfoo15x6P

We all know the benefits of exercise, but in space it’s what keeps us alive. Astronauts on board the @Space_Station work out for a massive 2.5 hours every day just to maintain muscle tone. Tune in for some space #Fitspiration ft. @AstroSerena #Horizons pic.twitter.com/XmwhUochJu

Wir alle wissen, wie wichtig Bewegung ist, aber im Weltraum ist sie essentiell. Wir Astronauten an Bord der #ISS trainieren täglich 2,5 Stunden lang, um den Muskeltonus zu erhalten. Schaut selbst: #Fitness ft. @AstroSerena #Horizons pic.twitter.com/gnEiCS9A2E

And so ends a brief period when there were two geophysicists in space at the same time. @Astro_Feustel is back on Earth while @Astro_Alex takes over command of the International @Space_Station. twitter.com/esaspaceflight…

With algae to Moon and Mars. Understanding how to grow algae in space might be the key to a successful closed life support system in future spacecraft. And it helps us to better understand Earth's ecosystem, too. #Horizons pic.twitter.com/KPpEYvJ9E3

Mit Algen zu Mond und Mars. Zu verstehen, wie man Algen im Weltraum züchten kann, könnte der Schlüssel zu einem funktionierenden geschlossenen Lebenserhaltungssystem in zukünftigen Raumschiffen sein. Und noch dazu hilft es uns, das Ökosystem unserer Erde besser zu verstehen. pic.twitter.com/nfyjg77HZG

As geophysicists, @Astro_Alex and I would like to thank all geoscientists around the world for the important work that they do to better scientifically understand our home for its’ inhabitants. We hope that some of you aspire to heights greater than ours on @Space_Station. pic.twitter.com/XmCAoMx3zD

A rare sight from the @Space_Station orbit: the pack ice of #Antarctica. Like space, this is another seemingly barren environment that we need to understand in order to protect our planet. #Horizons pic.twitter.com/wlbCJrfQFX
