Although NASA has been highly dependent on SpaceX in recent years, Space Launch Systems (SLS) will remain the agency’s biggest bet in the future,media reported. SLS is thought to be a rocket platform that sends humans back to the moon and deep into the solar system. Because it was delayed several times, it is hard to imagine that it is really done. Now, according to the latest reports, the latest estimates predict that SLS will be launched for the first time in the second half of 2021.
NASA has long planned to launch SLS in 2020. The time frame has been a significant delay from previous estimates, but NASA is sticking to its 2020 dream, even after the parts of the mission are not completed on time.
In addition, President Trump has ordered astronauts to return to the moon by 2024, but many are highly skeptical that the moon will be completed on time. There will be many moving parts on a lunar mission, plus human travelers, and you can imagine how much complexity it is.
As NASA’s own rocket systems continue to be pushed further and further away, it’s hard to imagine these things coming together in time.
