Artemis Lunar Landers
The Artemis Program will use Orion to transport astronauts to lunar orbit. From there, astronauts will transfer either to the Gateway Lunar Outpost for later transfer to a landing system, or transfer directly from Orion to a landing vehicle.
The lunar landing vehicle will be commercially built. On 30 April 2020, NASA designated three companies to design and build these systems. The companies designated are Blue Origin (Kent, Washington), Dynetics(Huntsvill, Alabama), and SpaceX (Hawthorne, California). At some point in the furure, NASA will select one of these three designs for use on Artemis missions.
Blue Origin established Blue Moon to design and develop lunar landing systems for NASA. They are working on a Cargo Land and a Human Landing System (HLS).
The HLS uses three elements composing its Integrated Landing Vehicle (ILV). Thes elements will be launched using Blue Origins own New Glenn and ULA's Vulcan Centaur.

The Transfer Element vehicle will move the HLS from a higher lunar obrit to an altitude at which the Descent Element can take over. It has been subcontracted to Northrup Grumman, and is based on Northrup Grumman's Cygnus ISS supply ship.

The Descent Element is being designed and built by Blue Origin, and is based upon their cargo lander. Descent guidance and avionics is being provided by Draper.

The Ascent Element is a reusable vehicle and is being built for Blue Origin by Lockheed Martin.

Dynetics is a subsidary of Leidos. The Dynetics lander (Dynetics Human Landing System or DHLS)has external propellant drop tanks which are discarded before landing. There are no separate descent and ascent modules. After landing, solar arrays are deployed. Transport to lunar orbit will be by ULA's Vulcan Centaur.

SpaceX is developing Starship, which a composite of the Starship itself and the Falcon Super Heavy launch vehicle. A modification of the Starship, stripped of its areodynamic fins and heat shielding, is the SpaceX entry for the lunar lander. The Starship lander is single stage and fully reusable. There are no descent or ascent stages. It will be sent into lunar orbit by SpaceX's Falcon Super Heavy.
