Juno's data showed a small but significant asymmetry between the gravitational field
of Jupiter's northern and southern hemispheres, driven by the immense jet streams.
This launch included a miniature version of a still being tested crew capsule, as well as an experimental satellite for cleaning space debris and a device for measuring the gravitational field
of the Earth.
It's not uncommon to think of up and down in space the same way we do on Earth--as movement against or along with a gravitational field
The authors cover object behavior in a gravitational field
, classical solutions of ordinary linear differential equations, Laplace transforms, the response of first and second-order systems, translational mechanical systems, rotational mechanical systems, and many other related subjects.
Searching for solutions to Einstein gravitational field
equations by proceeding from physical considerations to describe gravitational radiations.
The historic regularities are like the law on gravitational field
This, too, distorts time: Clocks run slower in a strong gravitational field
than they do in empty space.
If the sun were very slightly oblate, its gravitational field
would produce an additional drift of Mercury's perihelion.
Instead, researchers will measure the probe's speed reduction as it enters Phobos' gravitational field
to provide clues to its mass and density.
Spending time on Mars' much weaker gravitational field
, it would be almost impossible to readjust back to Earth's stronger gravity without, as if by a big Monty Python foot, being immediately squashed.
Mars One had not discounted the possibility of returning to Earth, however, it warned that it cannot be anticipated or expected because that would require a fully assembled and fuelled launch vehicle capable of escaping the gravitational field
of Mars, ample, on-board life support systems and supplies for up to seven months of voyage as well as capability to dock with a space station orbiting the Earth or perform a safe re-entry and landing on the planet where they originated.
mu]-] = ([PSI] / c, -D) 4-potential of gravitational field
which is described through scalar potential f and vector potential D of this field,
