Space Launch System
NASA’s Space Launch System (SLS) is a heavy-lift rocket, designed to offer a greater payload capacity than any before it. The Block 1 SLS was used by Artemis I, and has so far met or exceeded performance expectations. Rather than having a single fixed design, it is intended to be adaptable, so that it can be be manufactured in increasingly more powerful configurations, to accommodate missions with long range or heavy payload requirements. The goal is for the SLS to facilitate trips first to earth's moon, then to Mars.[1]
Configurations
Block 1
The first variant, called Block 1, can deliver a 59,500 pound payload to the moon. This design was used by Artemis I, and is planned for use also by Artemis II and III.[1]
Block 1B
In the Block 1B configuration, SLS is planned to carry 84,000 lbs into deep space. This is enough for not just the Orion crew module, but also a significant amount of cargo.[1]
Block 2
The Block 2 design is intended to carry 101,000 lbs into deep space. This is planned for use in moving significant amounts of hardware into space, and ultimately, to Mars.[1]
