A New Era of Missions Around the Moon

For the first time in more than half a century, humans are again flying around the Moon, not just sending robots. NASA’s Artemis II mission, launched on 1 April 2026, has carried four astronauts on a roughly 10‑day figure‑eight trajectory around the Moon to test the Space Launch System (SLS) rocket, the Orion spacecraft and the ground systems that will underpin a sustained lunar programme. This human flyby is happening alongside a dense schedule of robotic missions from China and others, signalling a transition from one‑off “flags and footprints” to repeatable, infrastructure‑driven operations in cis‑lunar space.

The strategic thread running through these missions is straightforward: governments are treating the region around the Moon as the proving ground for technologies — heavy‑lift launchers, autonomous systems, and in-situ resource use — that will shape not only space policy but also long-term industrial and defence capabilities.

Artemis II: How the Flyby Works

Artemis II is the first crewed Artemis flight and the first human trip beyond low Earth orbit since Apollo 17 in 1972. The mission profile sends Orion and its four-person crew — NASA astronauts Reid Wiseman, Victor Glover, Christina Koch and Canadian Space Agency astronaut Jeremy Hansen — on a free-return trajectory that loops behind the Moon and back to Earth without entering lunar orbit.

After launch and Earth‑orbit checkout, the SLS upper stage performs a translunar injection burn to send Orion toward the Moon. Around day six, the spacecraft passes the lunar far side at an altitude of roughly 4,000–6,000 miles (about 6,400–9,600 kilometres), far higher than the ∼70‑mile perilune of Apollo missions. That higher pass allows the crew to see the entire lunar disc, including polar regions, and to break Apollo 13’s record for the greatest distance humans have travelled from Earth by about 4,000 miles.

Operationally, Artemis II is a systems test: engineers are validating life‑support performance, deep‑space navigation, high‑rate optical communications and re‑entry under crewed conditions, all in an environment where free‑return dynamics guarantee that Orion will naturally fall back toward Earth if major systems fail. Those data will feed directly into Artemis IV and later lunar-landing missions, after NASA’s recent reshuffle that moved the first surface landing from Artemis III to Artemis IV and de-emphasised the Lunar Gateway in favour of more direct surface infrastructure.

China’s Relay Chain and Far Side Science

While Artemis II dominates human spaceflight headlines, China is quietly building an architecture around the Moon that is just as consequential. The Queqiao‑2 relay satellite, launched in 2024, now sits in a tailored lunar orbit to provide communications and data links between Earth and the Moon’s far side and south pole. It supported the Chang’e‑6 mission in 2024, which successfully returned the first-ever samples from the lunar far side, and is slated to support Chang’e‑7 and Chang’e‑8 later in the decade.

According to the China National Space Administration, Chang’e‑7 (around 2026) and Chang’e‑8 (around 2028) will target the lunar south pole and are expected to form the basic model of a joint lunar research station, carrying out long‑term environmental and resource exploration. That combination — persistent communications via Queqiao‑2 plus sequential surface missions — is effectively China’s answer to the Artemis architecture and underlines that cislunar space is no longer a single‑actor domain.

Why These Lunar Flybys Matter Beyond Symbolism

From an investor and policy standpoint, missions that fly around, rather than land on, the Moon are still pivotal.

First, they de‑risk hardware and operations for later, more capital‑intensive phases. Artemis II is validating the integrated performance of SLS, Orion and ground systems with a human crew, clearing a major hurdle on the path to cargo‑ and habitat‑scale missions. Similarly, Queqiao‑2 is proving out the relay model that future Chinese and partner missions will rely on for navigation, teleoperation and data relay in regions without direct line‑of‑sight to Earth.

Second, they accelerate standards and partnerships. Artemis and associated missions bring together NASA, ESA, JAXA, CSA and private contractors, creating a de facto standard-setting ecosystem for docking, life support, power systems and communications in lunar space. China’s programme is building a parallel ecosystem around the International Lunar Research Station concept, with different partners and potentially different norms on data sharing and resource use.

Third, they signal sustained funding. A programme that sends crews and complex robotic payloads repeatedly into lunar space implies multi‑year commitments to launch infrastructure, propulsion, robotics, AI‑based autonomy and in‑situ resource‑utilisation technologies. That has knock‑on effects for listed aerospace primes, satellite‑component suppliers, ground‑segment firms and downstream applications from Earth observation to telecoms.

What to Watch Next

Several indicators will show whether this renewed focus on missions around the Moon translates into the long‑term “Moon economy” that agencies describe.

• The performance and post‑flight reviews of Artemis II, particularly around Orion’s systems and SLS’s cost and reliability profile.

• Concrete design and schedule decisions for Artemis IV and V, including which commercial landers (from SpaceX, Blue Origin and others) are chosen and how often NASA aims to fly.

• Execution of Chang’e‑7 and Chang’e‑8 and the operational tempo of Queqiao‑2, especially if they begin hosting international payloads as planned.

Together, these missions suggest that flying around the Moon is no longer a stunt but a recurring step in a broader strategy: to treat cislunar space as the test range for the technologies and politics that will govern the next several decades of space activity.
