Es ist eine glorreiche Woche für extravagante, die Tiefsee erkundende, Millionäre. Nach James Camerons Tauchgang im Marianengraben hat nun JEff Bezos, Chef von Amazon, die Rakete auf dem Meeresboden ausfindig gemacht, die Apollo 11 am 16. Juli 1969 ins Weltall beförderte. Sie soll wahrscheinlich gehoben werden, gehört jedoch so oder so der NASA. Dass diese, sofern die Verfassung der Raketen es noch mitmacht, ins Smithsonian kommen werden, gilt als ziemlich wahrscheinlich. So mag ich mir meine Millionäre. Hier Bezos Blogeintrag:

Millions of people were inspired by the Apollo Program. I was five years old when I watched Apollo 11 unfold on television, and without any doubt it was a big contributor to my passions for science, engineering, and exploration. A year or so ago, I started to wonder, with the right team of undersea pros, could we find and potentially recover the F-1 engines that started mankind’s mission to the moon?

I’m excited to report that, using state-of-the-art deep sea sonar, the team has found the Apollo 11 engines lying 14,000 feet below the surface, and we’re making plans to attempt to raise one or more of them from the ocean floor. We don’t know yet what condition these engines might be in – they hit the ocean at high velocity and have been in salt water for more than 40 years. On the other hand, they’re made of tough stuff, so we’ll see.

Though they’ve been on the ocean floor for a long time, the engines remain the property of NASA. If we are able to recover one of these F-1 engines that started mankind on its first journey to another heavenly body, I imagine that NASA would decide to make it available to the Smithsonian for all to see. If we’re able to raise more than one engine, I’ve asked NASA if they would consider making it available to the excellent Museum of Flight here in Seattle. (For clarity, I’ll point out that no public funding will be used to attempt to raise the engines, as it’s being undertaken privately.)

NASA is one of the few institutions I know that can inspire five-year-olds. It sure inspired me, and with this endeavor, maybe we can inspire a few more youth to invent and explore.

We’ll keep you posted.

Sincerely,

Jeff Bezos

SpOn hat einen herzzerreißenden Artikel in ihrer einestages-Serie über unsere vierpfotigen Freunde namens Laika, Belka oder Strelka im Weltall.

Dass es nicht gut ausgehen würde, spürte der Russe Alexander Serjapin schon wenige Sekunden nach dem Start, als die Rakete aus ihrer Bahn gerissen wurde. Zwar korrigierte die automatische Steuerung den Fehler und brachte sie wieder in eine stabile Lage, doch dann sah Serjapin in der Bodenkontrolle die Katastrophe.

Kosmonautin Lissa wurde durch den heftigen Rückstoß wie Spielzeug aus der Rakete geschleudert. Und da flog sie in ihrem kleinen Spezial-Raumanzug durch die Atmosphäre und raste zur Erde zurück. Seine treue Lissa. 

“Das geschah alles mit solcher Gewalt, dass sie bei der Landung schon tot war”, erinnert sich Serjapin Jahrzehnte später mit leiser Stimme an das Unglück von 1955. “Ich musste sie in der Steppe begraben. So verlor ich meinen Liebling.”

Hunde-Kosmonauten. Wauwau im Weltall.

“Quite possibly the best YouTube video of all time.”

Neil ist badass wie immer und erzählt Stewart am Ende sogar eine wissenschaftliche Ungereimtheit am Intro seiner Sendung. Inspirierend!

The Expanding Light Echo of Red Supergiant Star V838 Monocerotis

V838 Monocerotis (V838 Mon) is a red variable star in the constellation Monoceros about 20,000 light years (6 kpc) from the Sun, and possibly one of the largest known stars. The previously unknown star was observed in early 2002 experiencing a major outburst. Originally believed to be a typical nova eruption, it was then realized to be something completely different. The reason for the outburst is still uncertain, but several theories have been put forward, including an eruption related to stellar death processes and a merger of a binary star or planets.

Rapidly brightening objects like novae and supernovae are known to produce a phenomenon known as light echo. The light that travels directly from the object arrives first. If there are clouds of interstellar matter around the star, some light is reflected from the clouds. Because of the longer path, the reflected light arrives later producing a vision of expanding rings of light around the erupted object. In addition, the rings appear to travel faster than the speed of light.

In the case of V838 Monocerotis, the light echo produced was unprecedented and is well documented in images taken by the Hubble Space Telescope.
