NASA to Test Cislunar Docking with CAPSTONE 02 Mission in 2027

NASA has awarded Advanced Space a contract for the CAPSTONE 02 mission, scheduled to launch in 2027 to test formation flights and docking in cislunar space. The twin satellites, each under 900 pounds, will practice techniques essential for future crewed lunar landings. The mission follows the initial CAPSTONE demonstration that used two microwave-sized spacecraft to navigate the Earth-Moon environment.

The Three-Body Problem

A three-body problem arises when an object is influenced by the gravity of two larger bodies, making trajectory prediction highly complex. In cislunar space, the region between Earth and the Moon, no simple formula governs spacecraft motion. The planned Artemis missions, starting with Artemis IV in 2028, will require Orion capsules to dock with landing vehicles and transfer astronauts while navigating this unstable zone. Past experience, including the Artemis II orbital flight, highlighted the risks of lunar operations without precise maneuvering data.

Cislunar Competition

NASA is not alone in seeking cislunar capabilities. China and SpaceX are also developing plans for lunar operations, turning the region into contested real estate. The U.S. Space Force has expressed interest in placing hardware there, signaling a rising strategic priority. Advanced Space and Terran Orbital Systems, the satellite designer, are positioning themselves as key contractors for deep-space navigation as both commercial and government demand grows.

What's Next

The exact launch window for CAPSTONE 02 in 2027 has yet to be set. It remains unclear whether the data from the twin satellites will be sufficient to reduce risks for the first crewed Artemis landing, now targeted for 2028.

NASA to send four Moon missions by late 2028 for base

NASA has awarded nearly $600 million for four commercial Moon landings planned for late 2028. Each mission will carry the same trio of science instruments to improve navigation, study lunar dust, and map radiation. The agency also unveiled plans for rovers, satellites, and cargo missions to support a permanent lunar base.

PSI releases new global maps of Martian subsurface water ice

Planetary Science Institute researchers release new global maps of Martian subsurface water ice, leveraging thermal data from NASA’s Mars Global Surveyor and Mars Reconnaissance Orbiter. The maps identify ice within a meter of the surface, a resource that could be converted into hydrazine rocket fuel for human missions. The team's cross-map comparison reveals discrepancies from instrument sensitivity and atmospheric dust.

Long space missions cause lasting harm to bones, heart, and eyes, twin study finds

Extended time in microgravity triggers bone mineral loss of 1 to 1.5 percent a month, muscle atrophy, and vision-threatening pressure changes inside the skull, according to NASA’s Twins Study and other research. Some of the alterations, including eye nerve flattening, still had not fully reversed months after astronauts returned to Earth. The findings sharpen one of the biggest open questions for a multi-year trip to Mars.

Artemis II triumph and White House cuts highlight NASA’s 2026 duality

In 2026, NASA flew astronauts around the Moon for the first time since 1972, while the White House proposed cutting the agency’s budget by 24%, with science facing a nearly 50% reduction. Congress later rejected the cuts and kept funding at approximately $24.4 billion. The contrast underscored deep tensions between human exploration and science priorities.
