NASA Launches Artemis II for First Crewed Lunar Flyby in 50 Years
NASA’s Artemis II mission launched on April 1, 2026, marking the first crewed lunar flyby in over 50 years with international crew and scientific payloads.
This article is based on an official press release from NASA.
Spurred by American ingenuity, astronauts on NASA’s Artemis II mission are officially in flight. According to a NASA press release, the Space Launch System (SLS) rocket lifted off from Launch Pad 39B at the Kennedy Space Center in Florida at 6:35 p.m. EDT on Wednesday, April 1, 2026. This milestone event marks the first crewed lunar flyby in more than 50 years.
The successful launch kicks off an approximately 10-day mission for NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space-Agencies (CSA) astronaut Jeremy Hansen. As we monitor the flight’s progress, the crew is already conducting critical systems tests aboard the Orion spacecraft, which they have officially named “Integrity.”
The SLS rocket, which generates 8.8 million pounds of thrust according to mission data, successfully propelled the Orion capsule into space. About 49 minutes into the flight, the upper stage fired to place Orion into an elliptical orbit. A subsequent apogee raise burn extended the spacecraft’s reach into a high Earth orbit, approximately 46,000 miles beyond Earth, as noted in the official agency release.
“Today’s launch marks a defining moment for our nation and for all who believe in exploration. Artemis II builds on the vision set by President Donald J. Trump, returning humanity to the Moon for the first time in more than 50 years… It marks our return to the Moon, not just to visit, but to eventually stay on our Moon Base,” said NASA Administrator Jared Isaacman in the press release.
The Artemis II crew represents several historic firsts for human spaceflight. Mission profiles highlight that Pilot Victor Glover is the first person of color on a lunar mission, Mission Specialist Christina Koch is the first woman, and Mission Specialist Jeremy Hansen is the first non-American to travel to the Moon.
Following separation from the upper stage, the crew immediately began putting the spacecraft through its paces. According to in-flight updates, Pilot Victor Glover and Commander Reid Wiseman successfully executed a 70-minute manual flight test. They utilized Orion’s onboard Navigation sensors and thrusters to maneuver near the detached Interim Cryogenic Propulsion Stage (ICPS), proving the capsule’s handling capabilities for future docking missions.
“Artemis II is a test flight, and the test has just begun. The team that built this vehicle, repaired it, and prepared it for flight has given our crew the machine they need to go prove what it can do,” stated NASA Associate Administrator Amit Kshatriya.
Spaceflight is rarely without its hurdles. According to recent mission updates, the crew encountered a minor malfunction with the spacecraft’s Universal Waste Management System, the onboard toilet. Mission Specialist Christina Koch reported a blinking amber fault light, which engineers traced to a jammed fan in the urine collection system. Working closely with Mission Control in Houston, the crew temporarily utilized a backup Collapsible Contingency Urinal (CCU) before successfully troubleshooting the controller issue and restoring normal operations.
In addition to the human crew, the mission carries secondary scientific payloads. The rocket’s upper stage is deploying four shoebox-sized CubeSats from Argentina, Germany, South Korea, and Saudi Arabia to perform scientific investigations in high Earth orbit. If all systems remain healthy, mission controllers will command the translunar injection (TLI) burn on Thursday, April 2. This six-minute firing will slingshot the spacecraft around the Moon on a free-return trajectory. At AirPro News, we view Artemis II as the mandatory proving ground for deep-space human exploration. While this mission will not land on the lunar surface, it is expected to break the human distance record from Earth. By traveling roughly 4,700 miles beyond the far side of the Moon, the crew will surpass the 248,655-mile record set by Apollo 13 in 1970. The successful demonstration of life support, radiation shielding, and manual piloting on this 10-day flight is an absolute prerequisite for Artemis III, planned as an Earth-orbit test of lunar landing procedures, and Artemis IV, targeted for a lunar South Pole landing in 2028. Ultimately, the data gathered during this flyby lays the critical foundation for future crewed missions to Mars.
According to NASA, Artemis II is a 10-day flight test of the Space Launch System rocket and the Orion spacecraft’s life support systems with a human crew, laying the groundwork for future lunar landings and deep-space exploration.
The crew consists of NASA astronauts Reid Wiseman (Commander), Victor Glover (Pilot), Christina Koch (Mission Specialist), and Canadian Space Agency astronaut Jeremy Hansen (Mission Specialist).
No. The mission is a lunar flyby on a free-return trajectory. It will travel around the Moon and return to Earth without landing or entering lunar orbit.

Pulsar Fusion Achieves First Plasma in Sunbird Fusion Rocket System
Pulsar Fusion successfully demonstrates first plasma in its Sunbird nuclear fusion rocket exhaust, advancing deep-space propulsion technology.
UK-based space propulsion Startups Pulsar Fusion has successfully achieved “first plasma” in its Sunbird nuclear fusion rocket exhaust system, marking a critical milestone in the development of next-generation deep-space travel. In a company press release, Pulsar Fusion announced that the successful test represents the first physical demonstration of plasma confinement within a nuclear fusion exhaust architecture designed specifically for spaceflight.
The breakthrough was showcased live during a dedicated technical session at Amazon’s MARS Conference in Ojai, California. According to the official release, the demonstration offers a glimpse into a future where interplanetary transit times could be drastically reduced, potentially revolutionizing how humanity explores the solar system.
The historic test was conducted by Pulsar Fusion scientists at the company’s headquarters in Bletchley, United Kingdom, and live-streamed to an audience of astronauts, Nobel laureates, and robotics experts at the MARS Conference. In the press release, the company detailed that the experiment utilized a combination of powerful electric and magnetic fields to guide and accelerate charged particles through the exhaust channel.
For this initial series of tests, the engineering team selected krypton gas as the propellant. The official release notes that krypton was chosen due to its relatively high ionization efficiency and inert characteristics at the mass flow rates required for early-stage testing. By successfully generating and confining the superheated plasma, Pulsar Fusion has cleared a major initial hurdle in harnessing fusion power for propulsion.
Current spacecraft rely heavily on chemical propulsion, which provides high thrust but low exhaust velocities, or Electric-Aviation propulsion, which offers high efficiency but very low thrust. Fusion propulsion aims to deliver both. According to the company’s press release, the Sunbird Migratory Transfer Vehicle is designed to provide continuous high-thrust propulsion for faster and more efficient travel.
Industry estimates reported by Gizmodo suggest that Pulsar Fusion’s Dual Direct Fusion Drive (DDFD) engine could achieve a remarkably high specific impulse of 10,000 to 15,000 seconds. Furthermore, according to World Nuclear News, the system is designed to generate 2 megawatts of power, providing both continuous thrust and electricity to run spacecraft systems upon arrival at a destination. With this technology, a fusion rocket could theoretically reach speeds over 500,000 miles per hour, according to reporting by Payload Space. This would allow spacecraft to cut the transit time to Mars by half and potentially reach Pluto in just four years, as outlined by World Nuclear News.
Following the successful first plasma test, Pulsar Fusion plans to gather detailed performance data, including thrust and exhaust velocity measurements, to plan the first official Sunbird mission. The press release outlines upcoming hardware upgrades, including the transition to rare-earth, high-temperature superconducting magnets. These magnets will enable stronger magnetic fields, allowing the team to explore higher plasma density and pressure conditions. To maximize the operational lifespan of the Sunbird engine, Pulsar Fusion has also partnered with the UK Atomic Energy Authority. According to the release, this collaborative research program will study the effects of neutron radiation on reactor walls and magnets, a primary cause of wear in fusion systems. Ultimately, the company aims to transition to aneutronic fusion fuel cycles, utilizing Deuterium and Helium-3. Pulsar Fusion is targeting an in-orbit demonstration of the system’s core components by 2027, with hopes for a production-ready vehicle in the early 2030s, according to timelines published by World Nuclear News.
The successful ignition of plasma in a fusion exhaust system represents a monumental engineering feat, but the road to a flight-ready nuclear fusion rocket remains long. Operating an engine at temperatures hotter than the sun’s core requires materials and containment systems that push the boundaries of current material science. However, the economic incentives are substantial.
“With the space economy projected to exceed $1.8 trillion by 2035, faster in-space transport isn’t just a scientific goal; it’s an economic one.”
, Pulsar Fusion statement, as cited by The Independent
This statement highlights the commercial viability of the project. If fusion propulsion can be mastered, we believe it will not only reduce the health risks for astronauts by shortening their exposure to deep-space radiation and microgravity but also enable rapid cargo delivery and asteroid mining missions that are currently unfeasible with chemical rockets.
In nuclear fusion, “first plasma” refers to the initial successful generation and confinement of superheated, ionized gas (plasma) within a reactor or exhaust system. It is a critical proof-of-concept milestone for fusion technology.
According to industry reports, the Sunbird nuclear fusion rocket could theoretically reach speeds exceeding 500,000 miles per hour, drastically reducing travel times to destinations like Mars and Pluto.
Pulsar Fusion plans to conduct an in-orbit demonstration of the system’s core components in 2027, with the goal of having a production-ready Sunbird vehicle operational in the early 2030s.
