NASA Ignition Timeline: Every Milestone from 2026 to 2033

Project Ignition is a seven-year program with an aggressive schedule of missions, hardware deliveries, and capability milestones. Some dates are firm, with hardware built and launch contracts signed. Others are aspirational targets that will shift as the program matures. We distinguish between the two throughout this timeline. For real-time tracking, visit our Ignition Tracker.

This timeline covers the Ignition program within the broader Artemis context, because Ignition depends on Artemis missions to deliver crew and major hardware to the lunar surface.

2026: The Foundation Year

Artemis II Crewed Flyby (Targeting April 2026)

Status: Hardware ready, launch date confirmed. Artemis II will send four astronauts — Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen — on a roughly 10-day flyby around the Moon aboard the Orion spacecraft, launched by SLS from Kennedy Space Center. This mission validates Orion's crew life support systems at lunar distance for the first time. The primary launch date is April 1, 2026, with backup windows on April 7, 8, 10, and 11. For viewing details, see our complete Artemis II viewing guide.

Project Ignition Announcement and Phase 1 Kickoff (March 2026)

Status: Announced. NASA Administrator Jared Isaacman announced Project Ignition on March 24, 2026, committing $20 billion over seven fiscal years (FY2027–2033) to build a permanent lunar base at the south pole. Phase 1 begins immediately with expanded CLPS procurement and technology development contracts.

CLPS Expansion Begins (2026)

Status: In progress. NASA is expected to issue new CLPS task orders at an accelerated pace under Ignition. Intuitive Machines, Astrobotic, Firefly Aerospace, and Draper are all eligible for new awards. Additional CLPS vendors may be selected as NASA scales the program toward the near-monthly delivery cadence targeted for Phase 1.

Key Risks for 2026

• Artemis II launch delay due to weather or technical issues (backup dates available through April 11)
• Congressional appropriations for FY2027 must include Ignition funding — the program depends on this first budget cycle
• CLPS mission reliability remains uncertain after the mixed results of early missions (IM-1 tipped, Peregrine failed)

2027: Proving the Architecture

Artemis III Earth-Orbit Test (Targeting 2027)

Status: Targeting, schedule dependent on Starship readiness. Artemis III is planned as an Earth-orbit demonstration of the Starship HLS rendezvous and crew transfer procedures. This mission will verify that astronauts can safely transfer between Orion and Starship in space — a critical prerequisite for crewed lunar landings. The exact date depends on Starship's flight test cadence and NASA certification milestones.

CLPS Monthly Cadence Begins (Targeting late 2027)

Status: Aspirational target. NASA aims to reach a near-monthly pace of CLPS deliveries to the lunar south pole by late 2027 or early 2028. Each delivery will carry instruments, technology demonstrators, or infrastructure components for Phase 1. Achieving this cadence requires multiple CLPS providers maintaining operational landers simultaneously.

Technology Development Awards

Status: Expected. NASA is expected to award contracts for nuclear surface power systems, ISRU pilot plants, autonomous construction equipment, and communication relay satellites. These awards will flow to both established contractors and small businesses through SBIR/STTR and directed task orders.

Key Risks for 2027

• Starship HLS schedule is the biggest single dependency — delays cascade to Artemis III and IV
• Scaling CLPS to monthly cadence is unprecedented and may take longer than planned
• FY2028 appropriations must sustain Ignition funding through the second year

2028: First Boots on the Ground

Artemis IV First Crewed Lunar Landing (Targeting 2028)

Status: Targeting, schedule not confirmed. Artemis IV is planned as the first crewed lunar landing since Apollo 17 in 1972. Astronauts would descend to the south pole surface aboard the Starship HLS, conduct surface EVAs in AxEMU spacesuits, and return to Orion in lunar orbit. This is the mission where boots touch regolith for the first time in over 55 years. The 2028 date is a target that depends on successful completion of Artemis III and Starship HLS certification.

Nuclear Surface Power Tests (Targeting 2028–2029)

Status: Development underway. NASA's Fission Surface Power project, developed in partnership with the Department of Energy, aims to deploy a small nuclear reactor on the lunar surface capable of generating 40 kilowatts of continuous power — enough to support a small habitat and ISRU operations. A terrestrial prototype is under development. Lunar deployment is targeting the late 2020s, with 2028–2029 the earliest realistic window.

Key Risks for 2028

• Any delay to Artemis III pushes Artemis IV and the entire crewed surface campaign
• Nuclear surface power is a first-of-its-kind system with no prior space deployment at this scale
• 2028 is a presidential election year — political attention to space programs may be minimal

2029–2030: Building the Base (Phase 1 Completion)

Regular Surface Missions

Status: Planned. With Starship HLS and Blue Moon operational, NASA targets one to two crewed surface missions per year starting in 2029, with surface stays extending from days to weeks. Each mission adds to the infrastructure at the south pole site.

Rover Deployments

Status: Development underway. Multiple rover systems are planned for delivery during this period: small autonomous rovers for site survey and resource mapping, medium rovers for construction support, and early mobility platforms. These arrive via CLPS landers and Starship cargo deliveries.

Site Preparation for Permanent Infrastructure

Status: Planned. Autonomous or teleoperated equipment will begin preparing the base site — leveling terrain, creating berms for radiation shielding, testing regolith-based construction techniques, and establishing the physical footprint for Phase 2 habitats. This is when the base transitions from a collection of instruments to a construction site.

Phase 1 Completion (Targeting 2030)

Status: Target. By the end of Phase 1, NASA expects to have validated the core technologies for permanent habitation: surface power (nuclear and solar), ISRU water extraction and electrolysis, autonomous surface operations, communication infrastructure, and regular crew access via Starship and Blue Moon.

Key Risks for 2029–2030

• Cumulative schedule delays from earlier phases could compress Phase 1 completion
• ISRU technology may perform differently in the actual lunar environment than in laboratory tests
• A new presidential administration (inaugurated January 2029) could adjust Ignition priorities or funding

2031: Semi-Habitable Infrastructure (Phase 2)

Extended Surface Stays

Status: Planned. Phase 2 begins the transition from short visits to multi-week or multi-month crew stays on the surface. This requires functional life support, reliable power, communication, and the ability to conduct meaningful scientific and operational work without constant resupply.

ISRU Operations at Scale

Status: Target. If Phase 1 ISRU experiments succeed, Phase 2 targets operational water extraction and oxygen production at a scale useful for mission support — reducing the mass of consumables that must be launched from Earth.

Key Risks for 2031

• Phase 2 depends entirely on Phase 1 delivering validated technologies on schedule
• Extended crew stays surface new challenges: medical events, equipment failures, psychological factors

2032: Major Hardware Deliveries

JAXA Pressurized Rover (Targeting 2032)

Status: Development underway. JAXA and Toyota are developing a pressurized lunar rover that will allow astronauts to drive across the lunar surface in a shirt-sleeve environment for multi-day excursions. The rover is currently targeting delivery to the Moon via Starship around 2032. This is one of the most significant international contributions to Ignition and transforms surface mobility from suited walks to extended exploration campaigns.

Additional Habitat Elements

Status: Planned. Phase 2 includes delivery of additional pressurized modules and surface infrastructure elements from NASA, international partners, and commercial providers. The exact manifest is still being defined as Ignition contracts are finalized.

Key Risks for 2032

• JAXA rover development is on Japan's budget and schedule — delays in Tokyo affect plans in Houston
• Starship cargo capacity is essential for the rover delivery; any Starship issues affect the timeline

2033: Permanent Human Presence (Phase 3 Target)

Blue Origin Habitat Delivery (Targeting 2032–2033)

Status: Development underway. Blue Origin's lunar habitat, part of the $3.4 billion Sustaining Lunar Development contract, is targeted for delivery during this period. This is intended to be one of the primary long-duration crew habitats at the south pole base, enabling continuous rotating crew presence.

Permanent Habitation Achieved (Targeting ~2033)

Status: Aspirational target. The culmination of the Ignition program is a base at the lunar south pole that is continuously inhabited by rotating crews. “Permanent” does not mean the same people stay forever — it means the base is always staffed, with crews rotating on a schedule similar to the International Space Station model (typically 6-month rotations on ISS).

Achieving this requires simultaneous success across multiple systems: reliable crew transportation (SLS/Orion + Starship or Blue Moon), functional habitats with life support, surface power, communication, ISRU, and a logistics pipeline that can sustain the base without interruption.

Beyond 2033

Ignition's budget authority runs through FY2033, but the base is designed to operate indefinitely. Potential expansions include:

• Lunar science laboratories for long-duration experiments in geology, biology, and physics
• Commercial activities including tourism, resource extraction, and manufacturing
• Deep space staging — using the lunar base as a waypoint for Mars missions and beyond
• Expanded international presence with additional partner habitats and facilities

A Note on Schedule Realism

Large NASA programs almost always experience schedule delays. SLS was originally expected to fly in 2017; it flew in 2022. The James Webb Space Telescope was supposed to launch in 2007; it launched in 2021. This is not a criticism — it is a pattern that applies to essentially every first-of-its-kind space system.

The Ignition timeline presented here reflects NASA's stated targets. Realistic expectations should add 1–3 years of buffer to the later milestones. A permanent human presence by 2035–2036, rather than 2033, would still be an extraordinary achievement — the first permanent off-world settlement in human history.
