Amanyathelo
Amaxabiso ahamba ngendlela eyodwa, ama-manoeuvres e-impulsive afanele uma kungaphawulwa okujwayelekile. Imizamo yangempela ifaka ukulahleka nokuguquka kweplanethi.

|---|---|---|---|---|
| Isimo sezulu | I-orbit yeplanethi ephansi (200 km) | 9.4 km/s | 0 km/s (ungasebenzisa ukubhuqa nge-aerobraking) | ojwayelekile (oshicilelwe): Delta-v budget (Wikipedia, with its cited references), typical values including lossesUkuqashwa kwe-orbit: cishe amakhilomitha angama-7.8/s wejubane le-orbit kanye nokulahleka kobunzima be-gravity ne-air drag. |
| I-orbit yeplanethi ephansi (200 km) | I-Geostationary transfer orbit | 2.45 km/s | 2.45 km/s (ungasebenzisa ukubhuqa nge-aerobraking) | ibalo (elifanele): Hohmann perigee burn, 200 km to 35,786 km altitude, equatorial |
| I-Geostationary transfer orbit | I-Geostationary orbit | 1.48 km/s | 1.48 km/s | ibalo (elifanele): Hohmann apogee burn, no plane changeKusuka endaweni yokuqashwa engaphandle kwe-equator, futhi ukuguqula i-orbit's tilt ongeza amakhilomitha ambalwa angamakhulu ngesekondi. |

| Thumela kuMsombuluko | I-orbital yenyanga ephansi (100 km) | 0.82 km/s | 0.82 km/s | ibalo (elifanele): Patched conic capture into a 100 km lunar orbit |
| I-orbital yenyanga ephansi (100 km) | Isimo senyanga | 1.63 km/s | 1.63 km/s | ibalo (elifanele): Circular speed at 100 km (ideal, no gravity losses; real landings need more) |
| I-orbit yeplanethi ephansi (200 km) | Thumela ku-Mars | 3.61 km/s | 3.61 km/s (ungasebenzisa ukubhuqa nge-aerobraking) | ibalo (elifanele): Earth-Mars Hohmann departure from 200 km, Oberth effect included |
| Thumela ku-Mars | I-orbit ephansi yeMars (300 km) | 2.09 km/s (ungasebenzisa ukubhuqa nge-aerobraking) | 2.09 km/s | ibalo (elifanele): Capture into a 300 km circular Mars orbit |
| I-orbit ephansi yeMars (300 km) | Isimo seMars | 0 km/s (ungasebenzisa ukubhuqa nge-aerobraking) | 4.1 km/s | ojwayelekile (oshicilelwe): Delta-v budget (Wikipedia, with its cited references), typical values including lossesUkuhlanganiswa kusetshenziswa kakhulu i-atmosphere (i-heat shield ne-parachutes); ukunyuka emuva e-orbit kuyinani elijwayelekile elibuzwayo. |
| I-orbit yeplanethi ephansi (200 km) | I-Asteroid eNkandla (Bennu) | 4.11 km/s | 4.11 km/s (ungasebenzisa ukubhuqa nge-aerobraking) | ibalo (elifanele): Heliocentric Hohmann 1 au to Bennu's semi-major axis, coplanar (ignores its 6 degree inclination and its eccentricity); departure from 200 km LEO |

Amathuluzi nama-lessons asebenzisa amamodeli alula ukufundela kuphela. Akufanele asetshenziswa ukuhlola, ukuhlela umsebenzi noma noma yiluphi ukhetho lokusebenzela. Izitifiketi zimahhala futhi aziqinisekisiwe. Funda isichazamazwi sezinto ezifundiswayo
