Snails in spacecrafts


This video says about itself:

n a galaxy not too far away, the Space Snails are the lowly garbage collectors and servants for the more important Aliens of the UAP (United Alliance of Planets). When a new Evil Alien menace threatens the Galaxy, the Space Snails discover that by pure luck they are immune, and inadvertently become the Heros of the entire Universe!!!

Now, about planet Earth snails …

By Jennifer Ouellette in the USA:

Pretty much since the dawn of the Space Age, scientists have come up with ingenious ways to test the effects of G forces and microgravity on the human body, right down to amusement park rides. One of the mechanisms used by the Apollo program was the dreaded human centerfuge; a 10×6 foot hollow sphere mounted on the end of a 50-foot arm that spun around rapidly to simulate “dynamic flight.”

Astronaut John Glenn memorably described it as “dreaded” and “sadistic” in his memoir, adding, “You were straining every muscle of your body to the maximum…. If you even thought of easing up, your vision would narrow like a set of blinders and you’d start to black out.” It was kind of a baptism by fire.

NASA has long since discontinued the use of centrifuges, although the US Air Force still operates a human centrifuge at its base in New Mexico. And their use aboard spacecraft has been proposed as a means of simulating gravity for long-duration manned space missions of the future, thereby reducing the effects of microgravity on astronauts (notably bone decalcification and muscle atrophy).

And now centrifuges are being used, apparently, to subject other creatures to the same conditions. A new paper by a team of US and Russian scientists that appeared this week on PLoS investigated the effects of microgravity on, well, snails. You heard me. Snails.

  1. Gagarin rocket reaches station

    KAZAKHSTAN: A Soyuz spacecraft named after the first human in space, Soviet cosmonaut Yuri Gagarin, delivered three new astronauts to the International Space Station on Wednesday, two days after blasting off from Baikonur Cosmodrome.

    Russians Andrey Borisenko and Alexander Samokutyaev, and Ronald Garan of the US, will spend six months aboard the station conducting about 40 experiments as part of a $100 billion (£61bn) project.

    The Soyuz launch on April 6 came less than a week before the 50th anniversary of Mr Gagarin’s historic flight from Baikonur.
