“Gosh, I’ve worked on Cassini for almost an entire Saturn year.”

Thursday, September 14th, 2017

BBC News: ‘Our Saturn years’. Cassini’s epic journey to the ringed planet, told by the people who helped make it happen. By Paul Rincon.

““The Voyagers gave us a really wonderful impression of Saturn. It’s a beautiful gas giant,” says Nasa’s director of planetary science Jim Green.

Prof Andrew Coates, from the Mullard Space Science Laboratory in Surrey, UK, agrees:

“Saturn is the most spectacular planet in our Solar System. The incredible rings, visible even in binoculars or a small telescope, make it stand out compared to all the rest.”

In places, the rings are only about as tall as a telephone pole. Yet from end-to-end they are more than 20-times as wide as the Earth. “

Some links for you science teachers out there:

ESA: Mission 1: Newton in Space (English). “While on board the ISS, Pedro Duque was filmed conducting demonstrations explaining Newton’s Three Laws of Motion”.

ESA: Mission 2: Body Space (English). “During the DELTA Mission, André Kuipers performed a number of physiology demonstrations showing the effects of weightlessness on the human body”.

ESA: Mission 3: Space Matters (English). “During the Eneide Mission in 2005, Roberto Vittori was filmed conducting demonstrations designed to explore the different structures, states and properties of matter”.


Für die Physik-, Biologie- und Chemielehrer vor den Bildschirmen: Diese Filme der ESA wurden ursprünglich auf DVD herausgebracht, sind aber inzwischen auf YouTube angekommen.

ESA: Mission 1: Newton in Space (Deutsch). Pedro Duque führte auf der ISS Experimente durch, die Newtons drei Gesetze für Bewegungen verdeutlichen.

ESA: Mission 2: Body Space (Deutsch). Auf der DELTA-Mission führte André Kuipers einige physiologische Experimente durch, welche die Auswirkungen der Schwerelosigkeit auf den menschlichen Körper zeigen.

ESA: Mission 3: Space Matters (Deutsch). Während der Eneide-Mission 2005 wurde Roberto Vittori gefilmt, während er Versuche zum Aufbau von Materie, ihren Eigenschaften und den Aggregatzuständen durchführte.

(Den ersten Film habe ich schon oft im Mittelstufenunterricht eingesetzt. Die deutsche Synchronstimme ist zwar etwas nervig, ich warne meine Schüler immer vor.)

What it says on the tin, the eclipse as seen from Wyoming, with a bonus appearance of the International Space Station. The ISS transit across the sun is fast, much faster than I thought it would be even though I’ve watched the ISS cross the sky many times.

Bonus link: Veritasium: Eclipse 2017 (YouTube, 5:20min), including time-lapse video from first contact to totality, viewed from Oregon.
