VEEGA trajectory
Galileo first used a telescope to observe the sky.
The first telescope was used by Galileo Galilei (first used in 1609) to see the faraway planets and stars of the galaxy.
Galileo used and made the first telescope.
Galileo used more advanced technology to find stronger observational evidence than Copernicus was ever able to provide.

Physics, and the associated mathematics, can be used to calculate a trajectory.
Gravity is not a form of energy. When a spacecraft manuevers near a planet in a certain trajectory, relative to the motion of the planet, the spacecraft will be accelerated at the expense of the planet; the planet slows down ever so slightly.
The Apollo spacecraft.
The shuttle program was a spacecraft that was reusable.
what was the name of the spacecraft used when Kathy Sullivan walked in otter space
To determine a trajectory line, only two points are needed. These two points can be used to calculate the slope, which represents the direction and angle of the trajectory. Additional points can be used to further refine the trajectory line and estimate its accuracy.
Spacecraft??? World War I came over 40 years before the first spacecraft.
Chemical rockets are generally used on manned spacecraft. Ion propulsion has been used on a few unmanned spacecraft.
Galileo first used a telescope to observe the sky.
The Hubble Space Telescope is a space observatory, not a spacecraft designed to carry people. It is operated remotely from Earth and was specifically built for a single purpose: astronomical observations.
