The discussion revolves around the mechanics of gravity slingshots and whether rocket propulsion is necessary for effective maneuvering during such maneuvers. Participants explore the implications of using alternative methods, like cannon fire, to achieve similar effects without traditional rocket guidance.
Participants express differing views on the necessity of rocket propulsion for effective gravity slingshots, with some arguing for its importance while others suggest alternatives. The discussion remains unresolved regarding the role of propulsion and the implications of the three-body problem.
The discussion touches on the complexities of trajectory calculations and the sensitivity of outcomes to initial conditions, which are not fully resolved. The definitions and criteria for stable solutions in N-body problems are also not clarified.
Slingshot depends only on the rocket having the right trajectory as it approaches the large object. If you can aim a cannon to put it there then it will get the gravity assist.Jonathan212 said:Is the gravity sling possible without rocket propulsion which dynamically guides the object to the right point? Ie, if instead of using a rocket, you shoot the object with an accurately aimed cannon from the moon, will it either hit the planet or miss it but never get slung/accelerated substantially?
Depends on whether or not they were already on the right trajectory.Jonathan212 said:Did the spaceships that used the slingshot make a turn with the rocket propulsion to get the right angle of approach?
