Dragon XL

By Dale Skran, Chair of the NSS Executive Committee

NASA today announced that SpaceX has been chosen to provide a cargo vehicle, the Dragon XL (illustrated above), to support the lunar Gateway as part of the Artemis program. It is expected that a second cargo provider for Gateway will be added to the program at a future time to provide dissimilar redundancy. The logistics contract has a maximum total value of $7 billion, so SpaceX may receive about half of this amount.

Contracts for two other key parts of Gateway—the Power and Propulsion Element (PPE) and the Habitation and Logistics Outpost (HALO)—have been won by Maxar Technologies and Northrup Grumman respectively.

The Dragon XL somewhat resembles the Cygnus vehicle currently used to supply cargo to the ISS. The Dragon XL can carry up to 5 metric tons to the Gateway in lunar orbit, and like Cygnus provides for the ISS, will offer garbage disposal services to the Gateway. The first flight of the Dragon XL, which will be launched on a Falcon Heavy, is targeted for the mid-2020s.

This unexpected announcement may be intended to show NASA’s commitment to the Gateway architecture and a sustainable return to the Moon in the context of pressure from the House (H.R.5666) to force NASA to not require Artemis lunar landers to dock with the Gateway for a 2024 lunar landing. Additionally, this contract demonstrates the intention of NASA to use commercial providers as part of Artemis rather than owning and operating all components itself. A major thrust of H.R.5666 (not yet passed by the House) is to force NASA to develop, own, and operate all human-class lunar landers that are part of Artemis. This approach effectively prohibits commercial participation in the provision of human-class lunar landers as part of early Artemis landings.

NASA has yet to fully describe an updated Artemis plan, so many aspects remain murky. Some speculations that arise from the Dragon XL announcement are:

  • Although Dragon XL is initially planned to fly to the Gateway, it presumably could also dock with the ISS to deliver larger amounts of cargo than will fit into the Dragon 2, and also to provide garbage disposal services to the ISS in the event that there is a problem with Cygnus.
  • Much as the Cygnus is a great candidate for a free flyer, Dragon XL might play a similar role with the ISS. The prospect of Cygnus and Dragon XL both providing commercial free flyer services to the ISS is a dramatic step forward for LEO commercial development.
  • Dragon XL is explicitly designed to be attached to Gateway for expansion purposes.
  • Dragon XL appears to be good candidate for a general purpose cis-lunar tug.

In matters unrelated to Dragon XL, if human class lunar landers are not required to dock at the Gateway, this opens the door to NASA making use of Starship/SuperHeavy further down the road in Artemis.

    • Could it be used to deliver modules to Gateway? it would seem that a Bigelow module would fit nicely between the docking port and service section?

  1. Looking forward to more information on the Gateway from NASA, particularly in regard to international participation. However, the existence of this contract removes the uncertainty on the medium-term utility of the Falcon Heavy for SpaceX.
