SpaceX Super Heavy vs NASA SLS: A Factual Comparison
SpaceX and NASA are two of the most significant names in the world of space technology. When it comes to rockets, these two companies are at the forefront of developing the most advanced and efficient rockets. SpaceX has introduced its new rocket, Super Heavy, whereas NASA's Space Launch System (SLS) has been in development for several years now. It's only natural for people to be interested in the comparison of the two. Let's have a closer look at the two rockets, assess their strengths and weaknesses, and find out how they stack up against each other.
Performance
The performance of a rocket is usually measured by its payload capacity and its ability to reach its target. Super Heavy can carry a payload of up to 100 metric tons, whereas the initial version of NASA's SLS can carry a payload of 95 metric tons, which is just a little bit less. However, NASA's SLS is designed to be upgradable, and in its final version, it will be able to carry 130 metric tons of payload, which leaves space for the possibility that it can outperform Super Heavy in the future. When it comes to the ability to reach their target, both rockets are designed to reach lower Earth orbit and the Moon.
Reusability
Both rockets are designed to be reusable, but SpaceX has a clear edge in this area. With reusable boosters, Super Heavy's design allows for significant savings in cost per launch. NASA's SLS, on the other hand, has components that can be recycled, but the rocket itself is designed to be expended.
Development and Costs
SpaceX has a history of developing technology that has allowed them to make rapid progress at a lower cost. The company has designed and developed its rockets independently and has pioneered innovative technologies such as reusable rockets, which have allowed them to optimize development costs. Super Heavy is on track to be launched in 2021, which is an impressive feat for a privately funded company. In contrast, NASA's SLS has been in development for almost ten years, and due to the large administration involved with a government-funded project, the production costs have been consistently higher than expected. NASA's SLS has already been plagued by delays and cost overruns, making it a more expensive option.
Conclusion
In conclusion, both rockets have their advantages and disadvantages. Super Heavy has a slightly higher payload capacity, better reusability, and is on track to be commercially operational sooner. On the other hand, NASA's SLS has the potential to surpass Super Heavy in payload capacity and is a government-funded project with a higher budget. Only time will tell which rocket will be the front-runner in the long run.
