The inaugural launch of the reusable Dream Chaser space shuttle to the ISS has been postponed once again.

According to the plan, the Dream Chaser shuttle will launch on the new Vulcan Centaur rocket from United Launch Alliance, departing from the Space Force station at Cape Canaveral in Florida.

During its test flight, the Dream Chaser will deliver 3.5 tons of cargo to the ISS. After spending approximately 45 days in orbit, the shuttle will return to Earth and will land automatically at the airfield like a conventional airplane.

According to data from Sierra Space, each Dream Chaser is designed for 15 missions.

Additionally, Sierra Space engineers are working on a second cargo spacecraft named Reverence, and they are also developing a series of inflatable modules for a future orbital station.
