The first launch of the carrier rocket SLS can do manned, but it will require a three-year delay

Last summer, NASA successfully tested the first stage of the carrier rocket Space Launch System (SLS). This booster after commissioning will be the lifting of the existing. In particular, to a low reference orbit, the rocket will be able to deliver 77 tons of cargo, a modernized version of which will appear later, increase this parameter up to 115 T. in addition, the SLS will be used in NASA Mars missions.

Previously, the first SLS launch was scheduled for 2018. According to the plans, in the process of launching an unmanned rocket will orbit the spacecraft Orion. However, NASA plans can change. The Agency is now considering the possibility of making the first manned launch. In addition, it should accelerate the return of man on the moon.

However, this change of plans would entail a considerable delay the first run. More specifically, in the case of the adoption of this decision, the SLS will make its first flight only in 2021. Additional time is necessary not only for more thorough testing, but for finishing the design, because the presence of people on Board the Orion will require the appropriate equipment that simply is not necessary in an unmanned launch (support system, management bodies and so on).

According to the original plans for the Orion spacecraft will stay in space for about three weeks, coming on the orbit of the moon (about 65 000 km above the surface). In the case of manned missions, the trajectory of the ship will be different. Likely, the ship will make several orbits around our satellite and return home.
