Starting at about 06:39 in this video: Most of the math {up to that point in the video} went over my head. HOWEVER, Dr. Maggie mentioning the planet losing as much momentum as the spacecraft gains is something I first became aware of reading Arthur C. Clarke's _novelization_ of *2OO1: A SPACE ODYSSEY.*
It sucks that it takes so long to reach the outer planets! I was twelve when the Voyagers launched and twenty four when Voyager 2 reached Neptune. I didn't seem that long back then, but I'll be retired by the time JUICE get to Jupiter and that seems like so much longer now.😄 Hopefully when Starship is operational we can get out there faster, it would be nice to re-visit Uranus and Neptune in my lifetime!🤞🤞 Thanks Dr. Maggie!👍👍
Kerbal Space Program and the Real Solar System mod for the game taught me so much about rocketry. At first I couldn't even get to orbit but after a year I can easily get to any planet or moon in the system.
Subscribed, 3th excellent video în a row. We need Nuclear thermal and Nuclear electric propulsion. I understand why Jupiter Icy Moons Orbiter was cancelled but the work on the nuclear reactor should have continued. We are still exploring the planets with an approach of the 80s (but with better computers to do even more fancy gravity assists). Clearly electric propulsion is not going to move the aircraft to Jupiter and then slowdown the spacecraft but Nuclear thermal will do (Yes SLS can do the job, but at 4 billion a pop to gain few years is too much)

Thank you for the orbital assist explanation, I had wondered how it was possible to gain speed overall if the gained speed by the "fall" was being lost on the way out, I didn't think about the planet or object itself and its effect on the speed!
Commenting to feed the complex equation of the algorithm. May it's increased mass provide a proper slingshot maneuver for more viewers to slow down and view this channel 🙃
Was JUICE supposed to use the moon and Earth to accelerate and decelerate from the start or was it redirected because of the fuel loss from the wonky antenna jam?
It was, although the exact calculations are always changing. JUICE was supposed to launch in 2022 and for that scenario it would have done 2 flybys of moon and Earth before Venus. The 1 year delay in launch meant they now have 1 flyby of moon and Earth before Venus but then 2 more after that
I would point out that gravity assists are not entirely free. You almost always need to do some kind of correction burn well ahead of the approach in order to nail the flyby corridor. The Oberth effect tends to dictate where in the orbit that correction burn ought to be.
Hi 😊 could you show more orbital mechanics with algebra using real numbers? How could we show navigation using x, y, and z coordinate systems? Thanks 😊
@@SpaceMog Without playing the world's smallest violin, the chances are pretty much nil. Thanks anyway, The most 'annoying' thing is all these great missions in the pipeline I'll never see.
Amazing! You can build a craft fuselage that absorbs every particle emission and send it at a gravity network of routes around the Solar system with almost minimal propulsion adjustments and nobody will ever detect it!😮
okay, your homework: how do we know where and when moons will be? i mean okay it can be worked out from observation, but i assume there is an almanac or a directory of the positions of most if not all planetary objects? we have catalogues for stars and galaxies, so i assume there is an equivalent for the planets and moons? i suppose i could look it up. again thanks for a great insight.
NASA's JPL (Jet Propulsion Laboratory in California) provides ephemeris (trajectories, basically a table of positions and velocities) of all the moons and planets and other objects in the solar system from observations.

@@SpaceMog easy, zinc and carbon elctrodes in a manganese solution gradually rip the battery off of the electrodes (ionisation in primary batteries is effectively irreversible) and generate an electric field in the process, causing an electrical tension measuring 1.5 volts when fresh
tricky question that i've asked on lots of science channels and never got a reply - why does squaring work? why ISN'T it E = MC almost squared or even E = MC not quite squared? how come squaring is a nice round figure? would squaring always work even if the speed of light was faster or slower? i do art, not maths dammit.
You can trace it back to Pythagoras theorem, the sum of two squares of a right angled triangle (i.e. the lines are perpendicular to each other, or act in separate dimensions) is equal to another square. The areas of the two squares when added is equal to the area of another square. So when you take the square root of that new area you get the length of the new line. Equations like E=mc^2 are also based on geometry of lines, but also it can be equated as momentum times energy (p=mv and E=pc) so when you replace the p with mv you get E=mvc, then using v=c (velocity equals speed of light) you get E=mcc=mc^2. Also the branch of mathematics called calculus is based on geometry, and if you integrate a variable you raise its power by one. For example integrating x you get x^2/2, integrating x^2 you get x^3/3. Integrating momentum (mass times velocity) you get the kinetic energy of a mass: integrate p=mv -> E=1/2 mv^2. I recommend studying basic geometry, algebra and calculus if you want to understand the math.
@@tonywells6990 thank you so much, but you haven't answered the question, which is, why does it round out nicely? what i was getting at is, yes, or course there is a physical requirement for - say - light to fade according to the inverse square law, for every one inch travelled, it becomes "four times weaker", the question is why is it "four times" and not "3.99 times" I DO NOT DOUBT YOUR MATHS, what boggles me is that it's a ROUND NUMBER, as opposed to a not quite a round number....... and if i'm, being dumb, bear in mind i'm an artist not a mathematician.

@@HarryNicNicholas It is a logical consequence of a conserved quantity as it is diluted through some geometry with straight lines. Just draw two lines from a point, then measure the area of a triangle made 5cm from the point, and another made 10cm from the point. You will find the 10cm triangle has 4 times the area of the 5cm triangle since the area is squared as you double the length. If the lines are not straight then you would find another ratio.
