What is astrodynamics

In celestial mechanics, escape velocity or escape speed is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a primary body, thus reaching an infinite distance from it.It is typically stated as an ideal speed, ignoring atmospheric friction.Although the term "escape velocity" is common, it is more accurately described as a speed than a ...

As another answer correctly stated, a Sun-Synchronous Orbit (SSO) with a Local Time of Ascending Node (LTAN) of 12 Noon would experience the maximum eclipse since the vector to the sun would lie within the orbital plane and an orbit with an LTAN of 11 AM would experience an eclipse time of close to that.Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets, satellites, and other spacecraft.

All crew skills works if got workstation, BUT they are way different to player skills, despite same name. For example piloting don't give thrusters nor unlocks class B and C ship piloting if the crew has it, but gives extra speed and manevaurability. So usually no unlocks and the given % is also different than player's. 38 Flight Range & Endurance Introduction. There are flight profiles and missions where there is a requirement for an aircraft to fly as far as possible (i.e., for the maximum flight range) or to stay in the air for as long as possible (i.e., for maximum flight endurance).The critical issue in both cases is the amount (i.e., allowable volume or weight) of fuel that can be carried on board the ...The core of poliastro are the Orbit objects inside the poliastro.twobody module.
