Artemis II schedule: When will NASA astronauts reach moon, return to Earth?

Artemis II launched April 1, 2026 at 6:35 p.m. ET on NASA's SLS with four astronauts for an approximately 10-day lunar flyby mission and a planned Pacific splashdown near San Diego on April 10, 2026. Key milestones: perigee raise and translunar injection on April 2, a lunar flyby passing up to ~6,000 miles above the far side with a 30–50 minute communications blackout on April 6, multi-burn trans-Earth return trajectory corrections April 7–9, entry interface April 9 and parachute-assisted reentry/splashdown April 10.

Analysis

The operational success of a crewed lunar sortie crystallizes demand not just for prime contractors but for a narrow set of high-reliability suppliers: Avionics/GN&C integrators, thermal protection (ablatives/composites), and radiation-hardened microelectronics. Expect procurement cycles to shift from one-off development buys to multi-year sustainment contracts across avionics firmware, parts obsolescence mitigation, and mission-specific testing capacity — a 12–36 month revenue tail for specialists rather than broad aerospace OEMs.

A key second-order effect is supply-chain consolidation risk: primes will prefer trusted single-source suppliers for flight-critical hardware, accelerating roll-ups or exclusive supplier agreements. That raises idiosyncratic counterparty concentration risk for OEMs dependent on a small set of vendors, and creates acquisition targets for larger defense primes looking to vertically integrate resilient subsystems over the next 18–36 months.

Catalysts that will re-rate equities are discrete: award announcements for lunar lander or relay-satellite contracts (0–12 months), congressional budget decisions (12–24 months), and any high-profile anomaly (days–weeks) that would trigger grounding or inspections. The contrarian angle: the market is overpaying for visibility in the large primes while underpricing mid-cap specialists whose revenue is >30% exposed to lunar/HEO programs — these names can see 30–100% multiple expansion if program repeatability is demonstrated and contracts shift from one-offs to sustainment.

Key Decisions for Investors

• Long LMT (Lockheed Martin) — buy Jan 2027 LEAP calls sized 2% portfolio. Rationale: Prime integrator optionality on Orion follow-ons and sustainment contracts; target +25–35% in 9–15 months if contract cadence persists, max loss = option premium; hedge with 1:1 short OTM puts if funding risk is a concern.
• Long MAXR (Maxar Technologies) — buy shares or 9–12 month calls (size 1–2% portfolio). Rationale: imaging/relay demand and modular spacecraft bus work make it a high-leverage play to lunar communications; target +40–60% on contract awards, downside -40% on tech/contract slips.
• Pair trade: Long NOC (Northrop Grumman) / Short BA (Boeing) — equal notional, 6–18 month horizon. Rationale: Defense prime exposure with lower commercial-cycle risk vs Boeing’s civil aerospace execution exposure; target relative outperformance 15–30%, tail risk if defense budgets are cut or Boeing operational recovery accelerates.
• Long HII (Huntington Ingalls) — buy 12–18 month calls or stock (size 1%). Rationale: naval recovery and maritime logistics roles benefit from increased crewed mission tempo and DoD integration; target +20–30% if program sustainment continues, downside -20% if sequestration or program cancellations occur.
