Kepler's Laws of Planetary Motion Described Using Earth Satellites
Johannes Kepler was born on December 27, 1571, in Weil der Stadt, Württemberg, in the Holy Roman Empire of German Nationality. Kepler moved to Prague to work with the renowned Danish astronomer, Tycho Brahe. He inherited Tycho's post as Imperial Mathematician when Tycho died in 1601. Using the precise data that Tycho had collected, Kepler discovered that the orbit of Mars was an ellipse. In 1609 he published Astronomia Nova, delineating his discoveries, which are now called Kepler's first two laws of planetary motion. Kepler noticed that an imaginary line drawn from a planet to the Sun swept out an equal area of space in equal times, regardless of where the planet was in its orbit. If you draw a triangle out from the Sun to a planet’s position at one point in time and its position at a fixed time later, the area of that triangle is always the same, anywhere in the orbit. For all these triangles to have the same area, the planet must move more quickly when it is near the Sun, but more slowly when it is farthest from the Sun. This discovery (which became Kepler’s second law of orbital motion) led to the realization of what became Kepler’s first law: that the planets move in an ellipse (a squashed circle) with the Sun at one focus point, offset from the center. In 1619 he published Harmonices Mundi, in which he describes his "third law." Kepler’s third law shows that there is a precise mathematical relationship between a planet’s distance from the Sun and the amount of time it takes revolve around the Sun. Kepler’s laws of planetary motion can also be used to describe the motion of satellites in orbit around Earth. This visualization introduces Kepler’s three laws of planetary motion using satellites in orbit around Earth. Several satellite orbits of varying characteristics are examined to see how Kepler’s laws apply. This version includes titles and labels.

How far would you have to go to escape gravity? - Rene Laufer

So why don’t we feel pulled in billions of different directions? And is there anywhere in the universe where we'd be free of its pull? Rene Laufer details the inescapability of gravity.

What Is Gravity Assist?
In orbital mechanics and aerospace engineering, a gravitational slingshot, gravity assist maneuver, or swing-by is the use of the relative movement and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft, typically to save propellant, time, and expense. Gravity assistance can be used to accelerate a spacecraft, that is, to increase or decrease its speed or redirect its path. Credit: CSA Follow Us:

What is a gravity assist?
2017-09-21 - Did you know that a spacecraft can use a planet’s gravity to change its orbit? For example, on September 22, 2017, the OSIRIS-REx spacecraft will use Earth’s gravity to change its orbit and help put it on course to asteroid Bennu, its target destination. With the help of this gravity assist, OSIRIS-REx is due to arrive at the asteroid in August 2018.

Crazy Engineering: Astrodynamics
NASA's Cassini spacecraft, in orbit around Saturn for nearly 13 years, is beginning its Grand Finale — and it's thanks to some Crazy Engineering! A team of engineers called astrodynamicists used math and physics to plot a course for the hardy spacecraft that would send it on a series of dives through the gap between Saturn and its famous rings. And as always, the efforts of these engineers are helping to enable some truly thrilling exploration and scientific discovery. More information about Cassini's Grand Finale is available at https://saturn.jpl.nasa.gov/grandfinale
Juice’s journey to Jupiter
This animation shows the proposed trajectory of ESA’s Jupiter Icy Moons Explore (Juice) mission to Jupiter. Based on a launch in June 2022, the spacecraft will make a series of gravity-assist flybys at Earth (May 2023, September 2024 and November 2026), Venus (October 2023) and Mars (February 2025) before arriving in the Jupiter system in October 2029. The animation ends at the Jupiter orbit insertion point, but the planned 3.5 year mission will see Juice not only orbit Jupiter, but also make dedicated flybys of the moons Europa, Callisto and Ganymede, before orbiting the largest moon, Ganymede.

Can An Astronaut Orbit The Space Station?
The space station masses over 400 tons, so can an astronaut orbit this? And what does this question have to do with supernova?
We can use Universe Sandbox 2 to simulate how the forces of gravity work down to small scales, but also how they interact in more complcated ways than most people imagine.
Asteroid Gravity Simulation - Forming a planet with rigid bodies in Maya // Warum Planeten rund sind
Follow me on Twitter: https://twitter.com/HellstormDe There hasn't been an update for a long time - but now there is it.
This time I'm using the Bullet Plugin for dynamics simulation. Because neither Maya's nParticles nor the Bullet Plugin itself support real gravity I had to write my own per-frame-script to simulate gravity.
The script calculates the gravitational force between each rigid body and then adds this force to the acceleration vector of the rigid body.
The initial asteroid belt is also created by a self-written script. It creates instances from a set of predefined shapes and gives them a random initial speed, rotation, mass and size. This time I've did the simulation with 4000 rigid body. The simulation ran at a speed of ~ 0.2 frames per second on an Intel Xeon E3-1231.
The length of the simulation was 400 frames and afterwards I stretched it to 1200 frames.
For the final test I want to do a simulation with 10.000 rigid bodies. The background is a 32000x16000 texture showing the calculated sky/milky way from the Tycho 2 star catalogue. I've created it also using a self-written program which parses the catalog data and adds the real color temperature to each star.
