What Happened
- NASA's Artemis II mission launched from Kennedy Space Center on 1 April 2026, sending four astronauts on a 10-day journey around the Moon — the first crewed lunar mission since Apollo 17 in December 1972.
- The crew comprises NASA astronauts Reid Wiseman (Commander), Victor Glover, and Christina Koch, along with Jeremy Hansen of the Canadian Space Agency — marking Canada's first deep-space mission.
- The mission uses the Space Launch System (SLS) rocket and the Orion spacecraft, which carries the crew.
- On Day 4 (4 April 2026), astronauts described seeing the far side of the Moon — the hemisphere permanently facing away from Earth — for the first time with unaided human eyes. Wiseman called it "not the moon I'm used to seeing."
- The crew also became the first humans to see the entirety of the Orientale basin — a massive multi-ring impact crater on the far side — with naked eyes.
- The lunar flyby window was set for 6 April 2026 (2:45–9:40 PM EDT), when Orion would pass within 4,066 miles of the Moon's surface at closest approach (approximately 7:02 PM EDT).
- At maximum distance from Earth (~7:05 PM EDT on 6 April), the crew is expected to travel 252,757 miles from Earth — breaking the Apollo 13 distance record by approximately 4,100 miles.
- During the 6-hour lunar science observation window, the crew views approximately 20% of the Moon's far side lit by sunlight, including Pierazzo crater and Ohm crater — features never previously observed by human eyes.
- The crew received geology training (classroom + field expeditions to Iceland and Canada + simulated flybys) to function as field scientists during the observation window.
- Artemis II is a test flight — it does not land on the Moon but validates the SLS–Orion system for future crewed landing missions.

The Artemis Program — NASA's Return to the Moon
The Artemis program is NASA's flagship human spaceflight initiative, formally established in 2017 under Space Policy Directive 1. Named after the twin sister of Apollo in Greek mythology, Artemis aims to land humans on the Moon again and ultimately establish a sustainable human presence in the lunar environment as a stepping stone to Mars.
The program's key milestones: - Artemis I (November 2022): Uncrewed Orion spacecraft orbited the Moon successfully, validating the SLS–Orion stack. - Artemis II (April 2026): First crewed test — lunar flyby, no landing. - Artemis III (2027, planned): Test of the Human Landing System (HLS) in Earth orbit; actual crewed landing pushed to Artemis IV. - Artemis IV (2028, target): First crewed Moon landing since Apollo 17 (1972). - Long-term goal: Permanent lunar base by the 2030s; human Mars missions thereafter.
- Launch vehicle: Space Launch System (SLS) — the most powerful rocket NASA has ever built, with ~8.8 million pounds of thrust at liftoff.
- Spacecraft: Orion — built by Lockheed Martin; the European Service Module (ESM) provided by ESA handles propulsion and life support.
- SLS is the only rocket that can send Orion, crew, and cargo directly to the Moon in a single launch.
- The Artemis program includes a planned Gateway lunar orbital station (with international partners) for long-term Moon operations.
- International partners: Canada (CSA), Japan (JAXA), European Space Agency (ESA), and others under the Artemis Accords framework.
Connection to this news: Artemis II is the critical crewed validation step. Its success unlocks the path to the Artemis IV landing and the broader goal of sustainable human lunar exploration.
The Far Side of the Moon — Why It Matters Scientifically
The far side of the Moon (also called the "dark side" colloquially, though it receives sunlight) is the hemisphere permanently facing away from Earth due to the Moon's synchronous rotation — its rotation period exactly equals its orbital period around Earth (both approximately 27.3 days). This means the same face always points toward Earth.
The far side is geologically distinct from the near side: it is more heavily cratered, has thicker crust, and lacks the large dark basaltic plains (maria) that dominate the near side. The South Pole–Aitken Basin on the far side is one of the largest known impact craters in the solar system.
The Orientale basin, now seen whole by Artemis II crew for the first time with human eyes, is a multi-ring impact structure approximately 930 km in diameter, straddling the near and far side boundary. It formed about 3.8 billion years ago and is scientifically significant because its structure reveals the mechanics of large-scale impact events.
- Synchronous rotation causes the permanent near side/far side division — this is the result of tidal locking over billions of years.
- China's Chang'e 4 (January 2019) was the first spacecraft to land on the far side — it communicated via a relay satellite (Queqiao) because direct radio contact with Earth is blocked.
- NASA's planned Artemis IV landing targets the lunar south pole — not far side, but near the permanently shadowed regions believed to contain water ice.
- The far side's isolation from Earth-based radio interference makes it a candidate site for future radio telescopes.
- Human eyes provide advantages over cameras for real-time geological observation: better dynamic range, contextual awareness, and color sensitivity.
Connection to this news: The Artemis II crew's observation of the full Orientale basin and other far-side features represents a scientific milestone that no prior human mission achieved — all Apollo missions flew to the near side.
Apollo Program vs. Artemis — Continuity and Differences
The Apollo program (1961–1972) landed 12 humans on the Moon across 6 missions (Apollo 11, 12, 14, 15, 16, and 17). The last human on the Moon was Apollo 17 astronaut Harrison Schmitt (a geologist) in December 1972 — over 50 years before Artemis II.
The gap between Apollo and Artemis reflects shifts in political will, budget priorities, and the complexity of sustainable (as opposed to flags-and-footprints) lunar return.
Key Differences: | Feature | Apollo | Artemis | |---|---|---| | Rocket | Saturn V (~7.6M lbs thrust) | SLS (~8.8M lbs thrust) | | Spacecraft | Command + Service Module | Orion + European Service Module | | Lunar lander | Lunar Module (LEM) | Human Landing System (HLS, SpaceX Starship) | | Crew diversity | All-male, all-American | Diverse; includes first woman (Koch) and first Canadian in deep space (Hansen) | | Science integration | No dedicated science officer in Mission Control | Dedicated Artemis Science Officers in Mission Control | | Goal | Demonstrate human Moon landing | Sustainable presence + Mars pathway | | International | Bilateral (US-USSR competition) | Multilateral (Artemis Accords) |
Connection to this news: Artemis II breaks Apollo 13's distance record and achieves the first crewed deep-space mission in over 50 years, marking a genuine continuation — not just repetition — of human lunar exploration.
Artemis Accords — International Framework for Lunar Cooperation
The Artemis Accords are a set of bilateral agreements between NASA and partner space agencies, establishing norms for peaceful, transparent, and responsible conduct in outer space — particularly around the Moon. The Accords are grounded in the 1967 Outer Space Treaty but go beyond it with specific provisions on interoperability, data sharing, deconfliction of activities, and the concept of "safety zones" around active operations.
- First signed in October 2020; over 50 countries had signed as of early 2026.
- Key signatories: USA, UK, Japan, Australia, Canada, UAE, India (signed October 2023), and many others.
- India's signing of the Artemis Accords in June 2023 — during PM Modi's state visit to the USA — was a significant milestone in India-US civil space cooperation.
- The Accords do not constitute a binding treaty; they are bilateral executive agreements.
- China and Russia have not signed; they are developing their own International Lunar Research Station (ILRS) program.
- Jeremy Hansen (Canada) flying on Artemis II is linked to Canada's contribution to the lunar Gateway station.
Connection to this news: India's participation in the Artemis Accords framework contextualises Artemis II as relevant to Indian foreign policy and space diplomacy, not just as a US mission.
