NASA’s upcoming Artemis II mission is the next crewed mission in the agency’s plan to explore the deep reaches of space. The mission is the next step following the uncrewed Artemis I mission. The mission will be crewed and will be sent using the Space Launch System rocket and the Orion spacecraft, launching from the Kennedy Space Centre in Florida.The mission will send the astronauts to the far reaches of the Moon and back to Earth. The mission, using the Space Launch System rocket and the Orion spacecraft, will test the spacecraft’s navigation, life support, propulsion, and communication systems, among other systems, while the spacecraft is crewed.
NASA Artemis II crewed test flight and mission objectives
Artemis II is a crewed test flight. It will send astronauts beyond low Earth orbit for the first time in the Artemis programme. The mission is focused on system verification rather than exploration activities on the lunar surface.The spacecraft will follow a free-return trajectory around the Moon. This path allows Orion to loop around the far side of the Moon and return without requiring major propulsion manoeuvres. It is a planned route used to support mission safety during early deep space flights.
Artemis II mission details: Launch date, time, and duration
The launch is scheduled for no earlier than 1 April 2026, with liftoff targeted at 6:24 p.m. EDT. The mission duration is expected to last for 10 days according to NASA reports. After launch, the rocket will place Orion into Earth orbit. The upper stage will then perform translunar injection to send the spacecraft toward the Moon.Following the lunar flyby, Orion will begin its return journey and re-enter Earth’s atmosphere. The mission will end with a splashdown in the Pacific Ocean, followed by recovery operations.
Who are the Artemis II crew members and their roles
PC: NASA
The Artemis II crew includes four astronauts:
- Reid Wiseman, Commander
- Victor Glover, Pilot
- Christina Koch, Mission Specialist
- Jeremy Hansen, Mission Specialist (CSA)
Each crew member has defined operational roles. The commander leads mission execution. The pilot assists with spacecraft systems and navigation. The mission specialists support system monitoring, communications, and onboard procedures. Training for the crew includes simulations, emergency procedures, and spacecraft systems operations. Their responsibilities extend across launch, transit, and re-entry phases of the mission.
Artemis II launch today: How to watch live
Viewers can follow the official broadcast from NASA on both YouTube and NASA+, the agency’s free streaming platform. The YouTube stream begins on Wednesday at 7:45 a.m. EDT, covering tanking operations and continuing throughout the full 10-day mission. The NASA+ broadcast offers a shorter, curated feed starting at 12:50 pm EDT, focusing on key moments such as crew suit-up and concluding after Orion’s solar arrays deploy following launch.Watch here:

Artemis II: Space launch system rocket and Orion spacecraft design details
As per the reports received from NASA, the launch vehicle will be the Space Launch System, which consists of four RS-25 engines in the core stage of the rocket, along with two solid rocket boosters. The Orion spacecraft is designed to carry astronauts to the Moon, which means it will go beyond the Earth’s orbit. The Orion spacecraft has a crew module, a service module, and a launch abort system.The launch abort system is designed to ensure the separation of the crew module in case of an emergency situation during the launch.
Artemis II launch countdown and procedures
Pre-launch operations commence several days before liftoff. Engineers conduct system checks on various components of the rocket and spacecraft. These checks involve diagnostics of engines, avionics, batteries, and communication systems.The Orion spacecraft’s flight batteries are fully charged. The batteries will be required during launch and early flight. The core stage’s batteries are also charged. The batteries will be required during launch. Engineers conduct pressure checks on astronauts’ suits in the Orion spacecraft that ensure the astronauts’ suits operate correctly. As countdown procedures approach their final phase, non-essential personnel leave the launch pad area. The ground launch sequencer commences operations. The ground launch sequencer is an automated system that executes the final countdown procedures. The system issues orders during countdown procedures, including engine ignition, valve operations, and system transitions.
Weather conditions for launch and its significance
Weather plays a key role in launch readiness. Forecasts for the launch window indicate generally favourable conditions. Monitoring includes cloud cover, wind speeds, precipitation, and possible electrical activity. NASA also works in collaboration with the US Space Force, specifically its Space Launch Delta 45, to assess conditions constantly. Weather limitations include wind, cloud, and lightning conditions. Ground winds and upper-level winds are also monitored to ensure vehicle stability. In addition, space weather is assessed, including solar flares and charged particle activity, which can interfere with communication and navigation systems. As of NASA’s latest March 30 blog update, the weather forecast shows an 80% chance of favourable weather conditions, with cloud coverage and potential for high winds on the ground as primary weather concerns.Continuous real-time monitoring is carried out until liftoff, and any violation of weather criteria results in a delay to protect the crew and mission hardware.
