How Space Probes Are Launched into Space | How did SpaceX Become a Successful Launcher Company?

The Space Launch System (abbreviated as SLS) is an American super heavy-lift expendable launch vehicle under development by NASA since 2011. The first launch, designated Artemis 1, is scheduled for a period between 20 September and 4 October 2022 from Kennedy Space Center. It replaces the Ares I and Ares V launch vehicles, which were canceled along with the rest of the Constellation program, a previous program aimed to return to the Moon. The SLS is intended to become the successor to the retired Space Shuttle, and the primary launch vehicle of NASA's deep space exploration plans through the 2020s. Crewed lunar flights are planned as part of the Artemis program, leading to a possible human mission to Mars. The SLS is being developed in three major phases with increasing capabilities: Block 1, Block 1B, and Block 2. As of August 2019, SLS Block 1 launch vehicles are to launch the first three Artemis missions and five subsequent SLS flights are planned to use Block 1B, after which all flights will use Block 2.

The SLS is planned to launch the Orion spacecraft as part of the Artemis program, making use of the ground operations and launch facilities at NASA's Kennedy Space Center in Florida. Artemis is projected to use at most one SLS each year until at least 2030. SLS will launch from LC-39B at the Kennedy Space Center.

The first launch was originally mandated by Congress for December 2016, but it has been delayed by more than five years to the original six-year

How did SpaceX Become a Successful Launcher Company?

Space Exploration Technologies Corp. (doing business as SpaceX) is an American spacecraft manufacturer, space launch provider, and satellite communications corporation headquartered in Hawthorne, California. It was founded in 2002 by Elon Musk, with the goal of reducing space transportation costs to enable the colonization of Mars. It manufactures Falcon 9 and Falcon Heavy launch vehicles, several rocket engines, Cargo Dragon, crew spacecraft, and Starlink communications satellites.

SpaceX is developing a satellite internet constellation named Starlink to provide commercial internet service. In January 2020, the Starlink constellation became the largest satellite constellation ever launched, and as of July 2022 comprises over 2,700 small satellites in orbit. The company is also developing Starship, a privately funded, fully reusable, super heavy-lift launch system for interplanetary and orbital spaceflight. It is intended to become SpaceX's primary orbital vehicle once operational, supplanting the existing Falcon 9, Falcon Heavy, and Dragon fleet. It will have the highest payload capacity of any orbital rocket ever built on its debut, scheduled for 2022 pending launch license.

SpaceX's achievements include the first privately funded liquid-propellant rocket to reach orbit around Earth; the first private company to successfully launch, orbit, and recover a spacecraft; the first private company to send a spacecraft to the International Space Station; the first vertical take-off and vertical propulsive landing for an orbital rocket booster; first reuse of such booster; and the first private company to send astronauts to orbit and to the International Space Station. SpaceX has flown and landed the Falcon 9 series of rockets over one hundred times.
