The Artemis II mission will mark humanity’s return to lunar exploration with a crewed spacecraft for the first time since Apollo 17 in December 1972. NASA’s Space Launch System rocket and Orion spacecraft will carry astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen on an approximately 10-day journey around the Moon and back to Earth.

The launch window opens on February 6, 2026, with additional opportunities on February 7th, 8th, 10th, and 11th. Launch will occur from Launch Complex 39B at Kennedy Space Center—the same historic pad complex that sent Apollo astronauts to the Moon aboard Apollo 10. After that, LC-39B was reconfigured for the Space Shuttle program, serving as the launch site for 53 missions.

Artemis II.

One of the goals of SLS was to reuse remaining hardware from NASA’s Shuttle program where possible. This was intended to be a cost-saving measure, but given the high price of a single SLS stack costs more than two billion dollars: The SLS rocket for Artemis II (and each Artemis mission) costs approximately $4.1 billion per launch per the NASA OIG, with about half of that being tied up in the rocket and capsule. That’s a lot of money.

Still, there a lot of previously flown pieces of hardware on America’s newest moon rocket.

Artemis II

SLS began its slow and deliberate journey to Launch Pad 39B from the Vehicle Assembly Building (VAB) early on January 17 at Kennedy Space Center, marking a major milestone in the agency’s quest to return astronauts to the Moon for the first time in more than half a century.

The 322-foot-tall rocket emerged from the cavernous Vehicle Assembly Building at 7:04 a.m. EST, carried atop Crawler-Transporter 2 for the four-mile trek to the historic launch complex. The combined stack — rocket, Orion capsule, and mobile launcher — weighs approximately 11 million pounds and is traveling at a top speed of just under one mile per hour.

SpaceX, NASA and the Crew 11 astronauts beat the clouds and rain showers and launched before summer showers washed over Kennedy Space Center today, but just barely. With dark skies and rain rapidly advancing from the south, liftoff of SpaceX’s 18th crewed flight was at 11:43 AM ET from venerable Launch Complex 39A. Crew 11’s four astronauts are now on their way to the International Space Station after today’s launch, with an expected arrival time at the orbital outpost around 3 AM ET tomorrow, August 2.

Gravity Turn: After Max-Q and now in its supersonic flight phase, Falcon 9 enters another gear, leaving the contrail it just made behind quickly. The cloud is from the rocket, not the storms it was escaping on August 1, 2025.

Tempus fugit, a lot of clocks say: “time is fleeting.” For a facility as established and enduring as Cape Canaveral Space Force Station, it might seem like forever since the first rocket launched from here. Time has flown and so have thousands of rockets and missiles from America’s premier spaceport. Truth is, CCSFS has been open “only” 75 years, but it continues to have a bright future not only today but also for the long-term future.
