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.

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.

A short animation showcasing how a circular orbit is projected as a wave on a flat map. I used a less polished version of this video in my recent kNews Space episode (https://www.youtube.com/watch?v=Y0yC1TtNXdo) and I also posted it on Reddit, where many came up with some really constructive feedback to make it better.

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

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.

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. http://universesandbox.com/

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.

Bill describes the Alignment Optical Telescope used in the Lunar Module on the Apollo missions to the moon. This telescope took star sightings which were used to align the Module's guidance system. Bill shows how the telescope used an Archimedes spiral inscribed on its eyepiece to replace the heavy motors, worm gears, and rigid tracks used in a traditional sextant -- this shaved weight from the Lunar Module and allowed it to carry more fuel.

See more space related talks by Brian Troutwine at #eef17 ow.ly/B9Xw307RzBd Slides and more info: http://www.codemesh.io/codemesh2015/brian-troutwine The Apollo Project was the first flight system to deploy with a digital, general-purpose computer at its core; the Apollo Guidance Computer (AGC). It was a complete research project: no digital computer had run consecutively for more than a few hours, sophisticated programming techniques were unknown and the human/computer interface had to be constructed to appeal to astronauts constitutionally opposed to machine interference in flight operations. In this talk I'll give the historical context for the AGC, discuss its initial design and the evolution of this design as the Apollo Project progressed. We'll do a deep-dive on the machine architecture and note how tight integration with a special-purpose vehicle admitted incredibly sophisticated behaviour from a primitive machine. We'll further discuss the human/computer interface for the AGC, how the astronaut's flight roles dictated the computer's role and vice versa. Motivating examples from select Apollo flights will be used. Throughout, we'll keep an eye on lessons to be gleaned from the experience of engineering the AGC and how we can adapt these lessons to modern computer systems in mission-critical deployments. Talk objectives: The intention of this talk is to describe the means and ways of what we now call embedded real-time software engineering in an engaging, historical context. Many of the techniques that are now dryly elaborated in textbooks were invented on the fly by engineers working on the Apollo Guidance Computer in the service of safely landing and retrieving men from the Moon. The audience is intended to learn: * systematic exploration of critical problem domains * embedded programming techniques for tiny computers * historical approaches to computing machines * the long-tail research that went into successful spaceflight to the moon Target audience: - General software engineers, people interested in spaceflight and critical systems engineers ought to enjoy the talk very much if all goes according to plan. About Brian Brian L. Troutwine is a software engineer with a focus on fault tolerance and real-time critical systems. He works extensively in Erlang and is a senior engineer with AdRoll on the real-time bidding project. Brian is likes things that go boom on failure.

This is a visualization of the trajectory designed by the ACT-ISAS team that won 1st place in the GTOC8. The theme chosen by NASA / JPL for the 8th edition of the GTOC was “high-resolution mapping of radio sources in the universe using space-based Very-Long-Baseline Interferometry (VLBI)”. Three spacecraft had to depart from the Earth and needed to perform several interferometric measurements of one of 420 radio sources. An interferometric measurement could be made when the three spacecraft lay on a plane whose normal pointed towards the radio source. Moon gravity assists and low-thrust propulsion had to be used to target each interferometric measurement.

Testing of Delta-V Maneuver

Earth=Green Moon=Yellow Satellite=Blue

Yellow=Earth's Moon Green=Earth

Earth's moon is represented by the yellow dot. Earth is represented by the green dot.

This simulation was produced using the Forward Euler Method of Numerical Integration and the Barnes-Hut Algorithm in the context of the gravitationally driven N-body problem that is a solar system's motion. Each body's initial position and velocity were obtained through an ephemeris provided by NASA's JPL. Shown in the simulation are (starting from the system's barycenter): Sun, Mercury, Venus, Earth, Moon, Mars. In this visualization Earth and its moon are barely distinguishable from each other, their system is identified by the orange dot and line. If zoomed in on the system of Earth and its moon, one would see that Earth's moon is indeed in orbit around Earth all the while both are in a heliocentric orbit.

Viewing Solar System Orbital Architecture through an Extrasolar Lens - Konstantin Batygin - SETI Talks The statistics of extrasolar planetary systems indicate that the default mode of planetary formation generates planets with orbital periods shorter than 100 days, and masses substantially exceeding that of the Earth. When viewed in this context, the Solar System, which contains no planets interior to Mercury’s 88-day orbit, is unusual. Extra-solar planetary detection surveys also suggest that planets with masses and periods broadly similar to Jupiter’s are somewhat uncommon, with occurrence fraction of less than approximately 10%. In this talk, Dr. Batygin will present calculations which show that a popular formation scenario for Jupiter and Saturn, in which Jupiter migrates inward from a greater than 5AU to approximately 1.5 AU and then reverses direction, can explain the low overall mass of the Solar System’s terrestrial planets, as well as the absence of planets with a less than 0.4 AU. Jupiter’s inward migration entrained s greater than 10 − 100 km planetesimals into low - order mean-motion resonances, shepherding of order 10 Earth masses of this material into the a ∼ 1 AU region while exciting substantial orbital eccentricity (e ∼ 0.2 − 0.4). He will argue that under these conditions, a collisional cascade will ensue, generating a planetesimal disk that would have flushed any preexisting short-period super-Earth-like planets into the Sun. In this scenario, the Solar System’s terrestrial planets formed from gas-starved mass-depleted debris that remained after the primary period of dynamical evolution.

Talk given by Prof. Lewin almost every year between 1996 and 2004 during the summer vacation for Science Teachers. This recording is from 1997. He discussed how to uncover the beauty of physics to students. He discusses the perception of seeing color and showed colors by using only black and white slides (the famous Edwin Land demo). He also covered (and demonstrated) Rayleigh Scattering which makes the sky blue and sunsets red. By holding cigaret smoke in his lungs he demonstrated why clouds are white.He uncovers the Physics of Rainbows and creates a rainbow during his lectures and he demonstrates (as he earlier arrived) that the rainbows are nearly 100% linearly polarized.
