Photo of the first national flag assembled by a human on the Moon (Apollo 11, 1969). With colonization of space having been a critically discussed issue since the dawn of the space age, resulting in the Outer Space Treaty (1967), the flag was not to symbolize any territorial claims.[1]

Example encounter.[2]In the planet's frame of reference, the space probe leaves with the exact same speed at which it had arrived. But when observed in the reference frame of the Solar System (fixed to the Sun), the benefit of this maneuver becomes apparent. Here it can be seen how the probe gains speed by tapping energy from the speed of the planet as it orbits the Sun. (If the trajectory is designed to pass in front of the planet instead of behind it, the gravity assist can be used as a braking maneuver rather than accelerating.) Because the mass of the probe is many orders of magnitude smaller than that of the planet, while the result on the probe is quite significant, the deceleration reaction experienced by the planet, according to Newton's third law, is utterly imperceptible.
