NASA really, really wants to send astronauts to the Moon and eventually other planets, but it currently doesn’t have a rocket capable of such feats. The Space Launch System (SLS) is NASA’s solution, but the development of the rocket has taken far longer — and cost far more — than the agency ever planned.

NASA’s most recent estimates suggested that it was still hopeful that the SLS would see its first test flight sometime in 2020. That unmanned mission would be a big milestone, but now it appears as though the agency has shifted its expectations a bit, with 2021 now looking far more likely.

NASA is about to grow fruit in space

NASA is about to grow fruit in space If humans begin to travel to other worlds on a regular basis — or even set up shop and live there — we're going to need food, and that means finding a way to grow fruits and vegetables in otherworldly environments. 

The following chart shows the number of launch systems developed in each country, and broken down by operational status. Rocket variants are not distinguished; i.e., the Atlas V series is only counted once for all its configurations " NASA Quietly Pushes Back Its SLS Launch Estimates to 2021 ".

The Space Launch System ( SLS ) is a US super heavy-lift expendable launch vehicle, which has been under development since its announcement in 2011.

As Ars Technica reports, NASA administrator Jim Bridenstine recently spoke to the US Senate Committee on Commerce, Science, and Transportation, and the dates he mentioned for the first launch of the SLS are a year later than all previous best-guesses.

In December, NASA Administrator Jim Bridenstine said that launch would take place in 2021 after the agency had been holding on a November Jurczyk said NASA is moving ahead with other elements of its exploration plan, including development of modules and related systems for the lunar Gateway.

This is the first launch of the large, costly, and delayed Space Launch System rocket that NASA hopes will serve as the backbone for its efforts to explore the Twice during testimony before the US Senate Committee on Commerce, Science, and Transportation, Bridenstine referenced 2021 as the expected

Bridenstine twice mentioned 2021 as being the date the agency is hoping that the Artemis-1 mission, the first SLS test launch, will take place. The administrator said 2021 was “definitely achievable,” but declined to hammer down anything more specific.

This is hardly the first time NASA has been forced to push back its SLS launch plans, and had the original timeline been possible we’d have already seen at least one SLS flight today. Delays have forced that schedule to change, and the expected first launch date was moved through 2019, and now 2020, to 2021.

These delays have also come at considerable financial expense to NASA, which now estimates that the program will cost billions of dollars more than originally expected. It’s worth noting that NASA is working with contractors including Boeing (which has failed to keep milestones for its Starliner spacecraft) and Northrop Grumman (which can’t seem to stop messing up the James Webb Space Telescope project) on the SLS program. I wonder why the SLS has been plagued with setbacks?
