Key Highlights
- Four astronauts began their historic 10-day lunar voyage as Artemis II lifted off Wednesday
- Boeing and Northrop Grumman constructed the SLS rocket; Lockheed Martin developed the Orion capsule
- Companies like Rocket Lab experienced significant stock increases amid heightened space sector momentum
- SpaceX, currently valued at $1.3 trillion, prepares for potentially record-setting $75 billion public offering
- Total investment in SLS and Orion exceeds $55 billion compared to SpaceX’s $12 billion lifetime funding
On Wednesday, NASA successfully initiated the Artemis II mission, propelling four crew members toward the moon for a 10-day expedition. Liftoff occurred at 6:24 p.m. EDT from Florida’s Kennedy Space Center during the designated launch window.
Action. Wonder. Adventure. Artemis II has got it all. Don't miss the moment. Our crewed Moon mission will launch as early as April 1.

The astronaut team comprises NASA’s Reid Wiseman, Victor Glover, and Christina Koch, alongside Canada’s Jeremy Hansen. Their journey will span approximately 700,000 miles total—establishing a new distance record for human space travel from our planet.
This expedition will eclipse the previous record established by Apollo 13, which encountered an emergency requiring mission abort during its lunar approach. Since 1972, no human beings have ventured beyond Earth’s orbital sphere.
Lockheed Martin partnered with Airbus to construct the Orion capsule transporting the crew. Additional hardware and systems were contributed by Northrop Grumman, L3Harris Technologies, and Honeywell.
The capsule launches aboard NASA’s towering 322-foot Space Launch System rocket. Boeing and Northrop Grumman served as primary developers for the SLS. NASA’s expenditure totals over $30 billion for the rocket system and an additional $25 billion for Orion development.
Previous delays stemmed from a hydrogen leak that necessitated returning the rocket to the assembly building for thorough examination. Launch director Charlie Blackwell-Thompson reported promising weather forecasts as Wednesday’s countdown progressed.
Market Response in Space Sector
Rocket Lab shares surged nearly 12% during Wednesday’s trading session. Redwire climbed 3.8% in premarket activity after highlighting that its imaging and navigation systems are integrated into the Artemis II mission.
Six publicly-traded space companies—Rocket Lab, AST SpaceMobile, Intuitive Machines, Firefly Aerospace, York Space Systems, and Redwire—command a collective market capitalization of $81 billion. This represents approximately 23 times projected 2026 revenue, with expectations calling for revenue to nearly double in the current year.
Both S&P 500 and Dow Jones futures registered gains of roughly 0.5% Wednesday morning.
SpaceX’s Anticipated Public Debut
SpaceX is responsible for more than half of worldwide orbital launches. Its Starlink satellite internet network operates over 10,000 satellites and serves more than 10 million customers globally.
The privately-held company currently carries a valuation near $1.3 trillion. Plans are underway for an initial public offering potentially generating up to $75 billion in capital—which would set a new record for American companies.
Throughout its existence, SpaceX has secured approximately $12 billion in total funding—dramatically less than NASA’s combined expenditure on just the SLS and Orion programs.
Future Artemis Missions
Scheduled for 2027, Artemis III will evaluate lunar landing systems developed by SpaceX and Blue Origin, founded by Jeff Bezos. Artemis IV, targeting 2028, aims to achieve the first American moon landing in over five decades.
NASA’s objective centers on creating a permanent human presence near the lunar south pole. China’s parallel pursuit of crewed lunar missions has intensified the timeline for U.S. efforts.
Several hours into their flight, the Artemis II crew will manually pilot the spacecraft to evaluate its controls and responsiveness before continuing their extended voyage.
