A sample of rock and dust retrieved from the asteroid Bennu contains water and carbon molecules, both building blocks for life as we know it, NASA chief Bill Nelson says. SOUNDBITE
Scientists used to say there were millions of tons of ice in the permanently shadowed craters of the moon’s poles. Now, HuffPost reports a pair of studies in the journal Nature Astronomy says there's far, far more potential water available. Twenty percent more, to be exact. A team led by the University of Colorado's Paul Hayne says more than 15,400 square miles of lunar terrain have the capability to trap water in the form of ice. However, lead researcher Casey Honniball says the molecules are so far apart that they are in neither liquid nor solid form. To be clear, this is not puddles of water. Casey Honniball, Lead Researcher Postdoctoral fellow, NASA’s Goddard Space Flight Center, Maryland Greater access to water could allow astronauts and robots more places to land, and support future lunar bases. Scientists believe the moon's water came from comets, asteroids, interplanetary dust, solar wind, or even lunar volcanic eruptions.
This man is Pavel Yusov, and he's spent the last five days suspended in water with his body wrapped in a waterproof suit. It's all part of an experiment called 'dry immersion' and the main goal of the project is to find out more about the effects of zero gravity on the human body. Scientists from Moscow's Institute of Medical and Biological Problems measure the physiological effects of microgravity after five days, conductin a full medical examination on the subject, similar to the checkups on cosmonauts and astronauts after they return from space. Even short exposure to microgravity causes the human body to lose muscle tone and decreases the ability to operate in earth gravity, but dry immersion experiments hope to help space travelers overcome these effects.
