Rockets aren't necessarily good for space travel they are a necessity. You cant leave earth without a rocket... you wont be able to break through the atmosphere.
Space travel is done by means of rockets.

Rockets are almost always used in space travel. It takes the thrust of the rocket to push the satellite or capsule to it's destination. 99% of the time, a rocket is used in space travel.

So far, technology has only allowed us to travel to space in rockets/space shuttles.
Rockets such as the Saturn V, Falcon 9, and Space Launch System (SLS) have been used to successfully launch spacecraft and travel into space. These rockets generate enough thrust to overcome Earth's gravity and propel spacecraft beyond our planet's atmosphere into space.
You need rockets so you can travel to space and visit other planets. Without rockets we would know nothing about astronomy.
Of course. Rockets in general have existed for hundreds of years. Rockets which travel to outer space have existed since the 1950s.
