The SLS is a Space Shuttle-derived launch vehicle. The first stage of the rocket is powered by one central core stage and two outboard solid rocket boosters. All SLS Blocks share a common core stage design, while they differ in their upper stages and boosters.

Examples of such efforts include the development of the Curiosity Mars rover, the Cassini-Huygens mission to Saturn and its moons, and the development of major space-based astronomical observatories such as the Hubble Space Telescope.

Interplanetary probes fly by celestial bodies. Orbiters are placed in orbit around a celestial body. Landers land on the surface of a celestial body.

Together, the SLS twin boosters provide more than 75 percent of the total SLS thrust at launch. The major physical difference between the shuttle and SLS boosters is the addition of a fifth propellant segment to the four-segment shuttle booster, allowing NASA's new launch-er to lift more weight than the shuttle.

There are numerous types of space technology used to explore the solar system. They are used to explore planets, moons, asteroids, and comets within the solar system. These include fly-bys, orbiters, landers, and rovers.

SpaceX's Falcon Heavy costs well north of $100 million per launch. The SLS? About $4 billion per launch, some sources say. And ing to veteran space reporter Eric Berger, it's at least $2 billion per launch.
