This will allow people to experience artificial gravity in space, which may be important for long-term missions to places such as Mars.

In the zero gravity of space, we could manufacture in 30 days lifesaving medicines it would take 30 years to make on Earth.
Albert Einstein published his theory of general relativity in 1916, offering a description of gravity, space and time that transformed how scientists understand the physical laws governing the known universe.
WSJ: Researchers Spent $750 million��and 52 Years��Affirming Theory of Relativity
Gravity measurements from space suggest the annual loss since 2003 has been running at about 70 billion tonnes, and it is accelerating.
In the zero-gravity void of interstellar space, the crafts might survive indefinitely, traveling the universe for all eternity.
So far, the birds have been bound by the all-powerful principle of gravity, but in space, that concept is going to get a little bent.
FORBES: The Ice Bird Cometh: Details From 'Angry Birds: Space'
This massive separation will allow it to measure the distortion of space as a gravity wave passes by.
At this point in space, the gravity of the Earth and the Sun act in such a way that the telescope will be stationary relative to the Earth and Sun.
You may be aware of Goce, the European Space Agency's gravity mapping satellite.
One is Einstein's general relativity, which deals with space, time and gravity.
The first maps not only record the three components but also compare their signals to the best available gravity field models assembled from existing space- and ground-acquired data-sets.
Let's get a kind of spider that can't build webs in space and that actually gravity is a factor in the way it hunts, so that's how the idea came.
CNN: Can jumping spiders kill in space? Student's experiment set for orbit
"When you have such a big mass in such a small space you have extremely high gravity, " said Charles Wang, a theoretical physicist at the University of Aberdeen, Scotland, who wasn't involved in the study.
Gravity, he figured, was a warping of space and time, and he came up with the equations that describe how the dynamics of this curvature result from the interplay between matter, motion, and energy.
This exploits one of the predictions of Einstein's general theory of relativity: that the path of a beam of light (which is a straight line in empty space) is bent inwards by the gravity of a massive object.
ECONOMIST: Cosmology: I spy with my little gravitational lens | The
Perhaps if we went on the space shuttle it would be--without gravity we'd be tall again.
Einstein's general theory of relativity states that objects with mass cause a curvature in space-time, which we perceive as gravity.
This barred scientists from using microplates in space, where researchers prize the absence of gravity for its insights into how crystals, bacteria and drug agents behave.
FORBES: Doing Science In Zero-G? You'll Have To Go Through Nanoracks
During the hour and a half flight, space nuts get a total of 450 seconds of zero gravity.
When opened and closed, these blinds--coated with a gravity-defying substance--initiate man's voyage into space.
It is more likely, then, that the object was floating free in space, and was captured by the sun's gravity in what was, in astronomical terms, the fairly recent past.
The details do not matter, except to say that this is precisely the sort of experiment that might be carried out in space, in order to eliminate the distorting effects of gravity.
Gravity was not a physical force but was caused by a curvature in space-time.
"From Einstein's theory of gravity, that is his general relativity theory, we believe mass curves space and this can cause light to follow a curved path, " he told BBC News Online.
Over a decade ago he helped pioneer the idea of the cube-sat satellite that is a small self contained box that could ride with other such boxes in the payload of a rocket where it could conduct low gravity experiments, biological experiments of do other interesting activities when released into space.
Indeed, theorists working on loop quantum gravity think that matter itself is merely the result of twisting and braiding ribbons of space-time.
And that's a great question because one of the hard things about long-duration space flight is the human body dealing with weightlessness and a lack of gravity.
WHITEHOUSE: President Obama's call to the International Space Station
As Iain Thomson puts it, it really might be time to take this space idea seriously and get on with getting up and out of this gravity well.
FORBES: Meteorites Are The Universe's Way Of Telling Us We Need More Than One Planet To Live On
"I've experienced 11 days docked at the space station, 16 days in space on my last flight, so getting back to life in zero gravity, that is never boring, everything from putting on your clothes to brushing your teeth to working to transfer of hardware, all of its fun in zero-g, " Marshburn told NASA before the launch.
If an object floating through space passes near the line of sight between the earth and a distant star, its gravity should, according to the theory of relativity, bend and focus the light from that star.
