Wednesday marked a historic milestone as NASA’s Artemis II mission blasted off from Florida’s Kennedy Space Center, initiating a 10-day circumlunar voyage with four crew members aboard. Liftoff occurred during a launch window that opened at 6:24 p.m. Eastern Daylight Time.
The astronaut crew comprises NASA’s Reid Wiseman, Victor Glover, and Christina Koch, alongside Canadian Space Agency’s Jeremy Hansen. Their journey will span approximately 700,000 miles round-trip, establishing a new record for human distance from Earth.
This voyage will exceed the distance milestone established by Apollo 13 during its troubled mission that required an emergency lunar flyby following a critical system failure. The last time humans ventured beyond Earth’s orbit was in December 1972.
Lockheed Martin, in partnership with Airbus, engineered the Orion crew capsule. Additional contributors including Northrop Grumman, L3Harris Technologies, and Honeywell provided critical components and subsystems for the spacecraft.
The massive 322-foot Space Launch System rocket serves as the launch vehicle, with primary development handled by Boeing and Northrop Grumman. NASA’s investment in the program has surpassed $30 billion for the SLS rocket alone, with an additional $25 billion dedicated to Orion development.
Previous launch attempts faced setbacks when hydrogen fuel leakage required engineers to return the vehicle to the assembly building for thorough inspection. Launch director Charlie Blackwell-Thompson confirmed favorable meteorological conditions ahead of Wednesday’s countdown sequence.
Rocket Lab shares surged nearly 12% during Wednesday’s trading session. Redwire experienced a 3.8% increase in pre-market activity after highlighting its imaging and navigation systems’ integration into the Artemis II mission.

A portfolio of six publicly traded space companies—Rocket Lab, AST SpaceMobile, Intuitive Machines, Firefly Aerospace, York Space Systems, and Redwire—currently commands a collective market capitalization of $81 billion. This valuation represents approximately 23 times projected 2026 revenues, with revenue expectations forecasting a near-doubling within the current fiscal year.
Broader market indices showed strength Wednesday morning, with both S&P 500 and Dow Jones futures advancing roughly 0.5%.
SpaceX dominates global orbital launch activity, conducting more than half of all worldwide missions. The company’s Starlink satellite constellation now exceeds 10,000 operational satellites, serving over 10 million broadband customers worldwide.
Current private market valuations place SpaceX at approximately $1.3 trillion. The aerospace company is advancing plans for an initial public offering that could generate up to $75 billion in proceeds, potentially setting a new benchmark for U.S. corporate IPOs.
Remarkably, SpaceX’s total capital raised throughout its corporate history amounts to roughly $12 billion—significantly less than NASA’s expenditure on the SLS and Orion programs combined.
Artemis III is scheduled for 2027 and will evaluate lunar landing systems developed by SpaceX and Blue Origin, the aerospace venture founded by Jeff Bezos. Artemis IV, targeted for 2028, aims to achieve the first American crewed lunar surface mission since the Apollo 17 mission in 1972.
NASA’s long-term objective involves creating a permanent human presence near the lunar south pole region. China’s parallel crewed lunar landing program has intensified the competitive timeline for American missions.
Several hours into the flight, the Artemis II crew will conduct manual piloting exercises with the Orion spacecraft, testing its control systems in preparation for more complex future missions.
