NASA officially awarded SpaceX the Human Landing System (HLS) contract on April 16, 2021. The selection marked a significant milestone in the Artemis program's development, positioning SpaceX as the sole contractor for lunar landing services.

The HLS contract allocated $2.9 billion to SpaceX through 2025 for the development of Starship as a lunar lander. The agreement covers one uncrewed demonstration mission followed by two crewed landings for Artemis III-V, with options for additional missions. SpaceX's contractual obligations include:

• Development of a lunar-optimized Starship variant
• Integration with NASA's Space Launch System
• Performance of test flights in Earth orbit
• Execution of a lunar landing demonstration
• Support for crew training operations
• Provision of mission control services

The HLS competition initially included three companies with distinct technical approaches:

• Blue Origin's National Team proposed a $5.9 billion multi-stage lander
• Dynetics presented a $9.1 billion single-stage concept
• SpaceX offered Starship at $2.9 billion with enhanced capabilities

The evaluation criteria focused on:

• Technical design maturity
• Management approach effectiveness
• Price reasonableness
• Mission feasibility assessment

NASA's source selection document cited SpaceX's proposal as the most technically capable with the lowest cost among competitors. Blue Origin's higher price point combined with technical complexity concerns influenced the final decision, while Dynetics' proposal faced challenges with mass margins specifications.

Company	Proposal Cost	Ranking
SpaceX	$2.9 billion	Selected
Blue Origin	$5.9 billion	Runner-up
Dynetics	$9.1 billion	Third place

NASA selected SpaceX's Starship as the Human Landing System (HLS) for the Artemis program based on its superior technical capabilities, innovative design solutions, and cost-effective approach to lunar landing operations.

SpaceX's Starship demonstrated advanced technical features that surpassed competing proposals. The spacecraft's 100-metric-ton payload capacity enables transportation of extensive cargo alongside crew members. The innovative propulsive landing system utilizes Raptor engines with precise throttling capabilities for controlled lunar descents. The spacecraft's elevator system facilitates safe crew transfer between different vehicle levels, while the spacious cabin provides enhanced crew comfort during lunar operations.

The Starship design incorporates full reusability features that reduce mission costs significantly. The $2.9 billion contract price represented less than half the cost of competing proposals, offering NASA substantial budget efficiency. SpaceX's established manufacturing infrastructure minimizes production expenses through standardized processes. The company's vertical integration model reduces supply chain costs by producing key components in-house, including:

• Raptor engines
• Propellant tanks
• Avionics systems
• Life support equipment

The reusable architecture enables multiple missions with the same vehicle, delivering long-term cost savings across the Artemis program timeline.

SpaceX's Starship serves as the Human Landing System (HLS) for NASA's Artemis program, facilitating the transportation of astronauts between lunar orbit and the Moon's surface. The spacecraft's advanced capabilities enable sustained lunar exploration through multiple missions planned between 2025 and 2030.

The Starship HLS operates through a multi-stage mission profile that begins in lunar orbit. The spacecraft first docks with the Orion capsule at the lunar Gateway or in lunar orbit, then descends to the lunar surface using its Raptor engines. The lunar variant features:

• Modified propulsion systems optimized for lunar operations

• Solar arrays generating 250 kW of power

• Large cargo bay accommodating 100 metric tons of payload

• Dedicated airlocks for lunar surface EVAs

• Landing legs designed for stable touchdown on lunar terrain

• Docking interfaces compatible with Orion spacecraft in lunar orbit

• Communication systems linked to NASA's Deep Space Network

• Standardized life support systems matching Gateway specifications

• Transfer mechanisms for crew movement between vehicles

• Shared mission control protocols between SpaceX and NASA facilities

Integration Component	Specification
Docking Height	8.1 meters
Crew Transfer Time	2-3 hours
Communication Delay	1.3 seconds
Power Transfer Rate	250 kilowatts
