Sierra Nevada Corp (SNC) and United Nations Office for Outer Space Affairs (UNOOSA) have formally converted their previous Memorandum of Understanding (MoU) to a full order for a Dream Chaser mission to carry hosted payloads from member countries. SNC’s Dream Chaser is a reusable spaceplane which will fly initially in 2019. The UN mission will take place in 2021.
