1. 1

   Ньютондук гравитация

   • Newton's gravity · 12 мин

     One law explains falling apples, the Moon's orbit and the path of every planet. Fire Newton's cannon and find out how.

2. 2

   Кеплердин мыйзамдары

   • Kepler's laws · 14 мин

     Three rules found from careful observations in the early 1600s still describe every orbit, from moons to exoplanets.

3. 3

   Орбиталдык элементтер

   • Orbital elements · 14 мин

     Six numbers pin down any orbit in space: its size, shape, tilt, orientation and where the body is on it.

4. 4

   Орбиталдык ылдамдыгы: vis-viva уравнения

   • Orbital speed: the vis-viva equation · 12 мин

     One short equation gives the speed of anything in orbit at any point, if you know how far it is and the size of its orbit.

5. 5

   Жылдамдык

   • Escape velocity · 12 мин

     How fast do you need to go to leave a world for good? And why rockets do not actually need to reach it at the surface.

6. 6

   Орбита эмне үчүн түшүп калуу

   • Why an orbit is a fall · 10 мин

     Astronauts float not because there is no gravity up there, but because they are falling all the time, and missing.

7. 7

   Орбитага жетүү: гравитациялык бурулуу

   • Reaching orbit · 12 мин

     Why rockets go up for only a few seconds, then spend ten minutes going sideways: the gravity turn, staging and orbital insertion.

8. 8

   Ракета теңдемеси жана дельта-v

   • The rocket equation and delta-v · 12 мин

     Why rockets are mostly fuel, why they come in stages, and the one equation behind every mission's budget.

9. 9

   Хоманн трансферлери

   • Hohmann transfers: changing orbits · 12 мин

     To go higher you speed up, and then you arrive slower. The two-burn manoeuvre that moves satellites from low orbit to geostationary orbit.

10. 10

    Терезелерди иштетүү

    • Launch windows: the road to Mars · 12 мин

      You cannot aim at Mars, only at where Mars will be in eight months. Why Mars missions leave every 26 months, all at once.

11. 11

    Орбиталык киргизүү: кармалууда

    • Orbital insertion: getting captured · 12 мин

      Arriving at a planet is the most dangerous minute of a mission: one burn decides whether you stay or fly past forever.

12. 12

    Гравитациялык жардам

    • Gravity assists: the free slingshot · 12 мин

      How Voyager, Cassini and New Horizons stole speed from planets, and why it never breaks the conservation of energy.

13. 13

    Лагранж пункттары

    • Lagrange points: balance in the sky · 11 мин

      Five places around every pair of worlds where a spacecraft can ride along for free, and why the James Webb Space Telescope lives at one of them.

14. 14

    Рендью жана доктоо

    • Rendezvous: catching the space station · 11 мин

      To catch something ahead of you in orbit, you drop lower and go slower-looking but faster. The counter-intuitive art of meeting in space.

15. 15

    Үйгө келүү: кайра кирүү

    • Coming home: reentry · 11 мин

      A small push slows a spacecraft by a hundred metres per second, and the air takes care of the other 7.8 kilometres per second, as a fireball.
