The United States and China are locked in a multi-billion dollar sprint to claim permanent lunar real estate before the end of the decade. That intense geopolitical pressure is the silent engine driving the Artemis II mission right now. Four astronauts are currently hurtling through deep space on a 10-day lunar flyby. They are serving as the ultimate test subjects for NASA’s new hardware.
The crew is officially moonbound. They passed the halfway mark to the lunar surface this weekend. Canadian astronaut Jeremy Hansen and American astronauts Reid Wiseman and Christina Koch fielded questions from Canadian youth during a live broadcast early Sunday morning. They spoke directly from inside the Orion spacecraft on Day 4 of their historic flight.
Living in microgravity is physically punishing. Hansen explained to the students that the lack of gravity causes blood to pool in their upper bodies. This gives the astronauts a distinct puffy face.
Koch elaborated on the internal changes. She noted that their hearts do not have to work as hard to pump blood. She also pointed out the long-term risk of kidney disease associated with deep space travel. When asked to compare their reality to Hollywood, Hansen selected the 1995 film Apollo 13 as a highly accurate depiction of surviving inside a tiny capsule.
The crew has a spectacular view. They reported seeing a partial crescent Earth and sections of dark Earth as they share Earth photos with mission control.
The flight has not been flawless. The crew recently dealt with a malfunctioning wastewater vent nozzle caused by ice buildup. They temporarily used backup collapsible contingency urinal bags. Ground controllers fixed the issue by angling the Orion spacecraft directly toward the sun to melt the ice. Normal toilet operations are restored.
🚀 LIVE UPDATE: Where Artemis II is now… on Translunar Coast 🌕
Where Artemis II is now… and what happens next 🌑

The four-person crew will execute their critical lunar flyby on Day 6. They are scheduled to splash down in the Pacific Ocean off the coast of San Diego on April 10.
Why This Deep Space Proving Ground Defines The Next 50 Years
This is the first crewed mission to the Moon in 54 years. The physical reality of leaving low Earth orbit is vastly different than missions to the International Space Station. The Artemis II mission is shattering demographic boundaries. Hansen is the first non-American to travel to deep space. Koch is the first woman on a lunar mission. Victor Glover is the first person of color to leave low Earth orbit.
NASA is using this specific flight to validate the Orion capsule’s life-support systems. The agency needs absolute certainty that this hardware works before they commit to building the Lunar Gateway outpost. The shift from Cold War-era nationalism to a model of global collaboration with agencies like the Canadian Space Agency is a deliberate strategy to outpace China’s 2030 lunar landing goal. The success of this 10-day flyby dictates the timeline for a permanent human presence on the Moon.
