NASA Selects Four-Person Crew for Artemis III Orbital Docking Test Mission in 2027

1 source

NASA announced on June 9 that three US astronauts (Andre Douglas, Frank Rubio, Randy Bresnik) and Italian astronaut Luca Parmitano will crew Artemis III, a 2027 mission to test SpaceX's Starship and Blue Origin's Blue Moon landers in Earth orbit before lunar surface missions. The two-week mission will involve multiple spacecraft docking and testing in low-Earth orbit, serving as a critical validation of the landers before crewed moon landings. The mission represents a key step in NASA's Artemis program to establish long-term human presence on the moon amid competition from China's 2030 lunar landing target.

NASA named the crew for Artemis III on June 9, selecting US astronauts Andre Douglas, Frank Rubio, and Randy Bresnik alongside Italian ESA astronaut Luca Parmitano. Scheduled for late 2027, the mission will conduct the first in-space test of SpaceX's Starship and Blue Origin's Blue Moon lunar landers through a complex orbital docking sequence in low-Earth orbit. The spacecraft will launch separately—Blue Moon first, followed by NASA's Orion capsule carrying the crew, then Starship—and will dock with Orion for testing and technology demonstrations before returning to Earth. This mission follows Artemis II, which flew four astronauts around the moon in April 2024, and precedes planned lunar surface landings. The mission was restructured in 2025 after SpaceX and Blue Origin proposed accelerated development timelines, replacing earlier plans for a lunar Gateway station. Both companies have faced development delays, with Blue Origin's New Glenn rocket exploding in May 2024, though the company expects to resume launches by year-end.

Study Examines How 'Undone Science' Shaped Chile's Glacier Protection Conflicts

A new study published in Tapuya: Latin American Science, Technology and Society explores how gaps in scientific knowledge enabled mining projects to avoid scrutiny in Chile's glacier conservation debates. 'Undone science'—areas of knowledge that are absent or contested—allowed significant environmental impacts to escape regulatory attention over two decades. The research highlights how incomplete scientific understanding can shape environmental policy outcomes globally.

Mathematical Framework Unifies Three Theories of Brain Dynamics Through Single Operator Model

Researchers propose that three distinct mathematical frameworks for describing brain dynamics—connectome harmonics, turbulence, and complex harmonics—can be unified as different expressions of a single self-adjoint operator based on the connectome Laplacian. The study tests this prediction using LSD as a pharmacological perturbation, finding that harmonic energy redistribution and turbulence shifts respond in unison to structural changes in the operator. This unification could provide a fundamental mathematical foundation for understanding how brain structure constrains neural dynamics across multiple scales.

ACTRT2 Protein Loss Causes Male Subfertility and Acrosome Defects in Mice

Researchers found that loss of the ACTRT2 protein in mice causes male subfertility and malformed acrosomes (sperm head structures) during development. ACTRT2 is a conserved protein that localizes to the perinuclear theca and interacts with multiple other testis-specific proteins to regulate actin dynamics. The findings establish ACTRT2 as a key structural regulator of sperm head architecture and male fertility.
