For the first time in over 50 years, humanity is on the verge of returning to the vicinity of the Moon.As of today, April 1, 2026, the countdown for the historic Artemis II mission is officially in its final hours.
NASA has set a targeted launch time for 6:24 p.m. EDT. This mission marks a pivotal moment in the Artemis program, serving as the first crewed test flight of the Space Launch System (SLS) rocket and the Orion spacecraft.While the mission won't land on the lunar surface—that feat is reserved for Artemis III—it will carry four astronauts on a 10-day journey around the Moon’s far side, shattering distance records for human-rated spacecraft.
Prediction markets such as Kalshi are offering event contracts on when the official launch of Artemis II will happen. Find the live odds below, and if you want to trade for yourself, claim the Kalshi promo code from Action Network.
Live Kalshi Odds: When Will Artemis II Launch?
The following market reflects the real-time probability of the launch occurring by specific dates. If technical delays or weather push the date back, new markets for later in April and May will likely appear on Kalshi:
A Brief History of the Mission
Artemis II is the spiritual successor to Apollo 8, the 1968 mission that first took humans to the Moon. However, the technology powering this journey is vastly different.
The mission follows the success of Artemis I in late 2022, which proved the SLS rocket and Orion capsule could survive the intense heat of reentry—hitting the atmosphere at roughly 25,000 mph.
The crew for this flight is as historic as the mission itself:
Reid Wiseman (Commander): NASA veteran.
Victor Glover (Pilot): Set to become the first person of color to leave low Earth orbit.
Christina Koch (Mission Specialist): Set to become the first woman to travel to the Moon.
Jeremy Hansen (Mission Specialist): The first non-U.S. citizen (representing Canada) to head for deep space.
The "Scrub" Factors: What Could Stop the Launch?
Even with a "Go" for launch planned for today, spaceflight is notoriously unpredictable. Prediction market apps are currently pricing in a high probability of success, but seasoned observers know that two main factors often lead to a "scrub" (delay):
Weather Constraints: NASA and the U.S. Space Force are currently monitoring an 80% chance of favorable weather.However, the SLS cannot launch through thick clouds, precipitation, or if there is a threat of lightning within 10 nautical miles. High-altitude wind shear is also a silent killer for launch dates; if the winds are too strong for the rocket to maintain structural integrity during ascent, the mission will be pushed.
Technical "Glitches": The SLS is a complex beast fueled by over 750,000 gallons of super-cooled liquid hydrogen and liquid oxygen. In the past, "hydrogen leaks" have plagued the countdown. While NASA has updated the seals and fueling protocols, any sensor reading that falls outside of strict tolerances will trigger an automatic hold.
The Path to the Moon
If Artemis II clears the pad today, it paves the way for a sustained human presence on the lunar surface and the eventual "Gateway" station. While NASA is leading the charge with the SLS, the broader lunar economy is booming. Private partners like SpaceX are already integral to the program's future, with Elon Musk's company contracted to provide the Starship Human Landing System (HLS) for the Artemis III mission that will actually put boots back on the ground.
If today’s window closes without a roar from the RS-25 engines, the next opportunities will depend on the "lunar alignment" and the time needed to recycle the rocket's cryogenic systems. Keep an eye on the Kalshi markets above, as the odds will shift the moment a "Hold" is called or the final "Go" is given.
