2 Min Read I Am Artemis: Joe Pavicic
Listen to this audio excerpt from Joe Pavicic, Artemis operations project engineer

Your browser does not support the audio element. Joe Pavicic will never forget when he told the Artemis launch director teams were NO-GO for launch.
Before Artemis I lifted off from NASA’s Kennedy Space Center in Florida in November 2022, the launch team made multiple launch attempts the months prior.
“During a previous Artemis I launch attempt, there was an issue with engine three,” said Pavicic, operations project engineer who worked on the engines console during Artemis I. “One sensor was showing that it wasn’t seeing liquid hydrogen through it. It was showing that it was at ambient temperature.”
And I had to tell the launch director, ‘We can't get there today with the current criteria that we have. My recommendation is a NO-GO.’
Joe pavicic
Operations Project Engineer
Prior to engine ignition, launch team controllers must first chill the engines before the cryogenic liquid propellant fuels and lifts the SLS (Space Launch System) rocket and Orion spacecraft into the heavens and onward to the Moon. Chilling the engines ensures the hardware doesn’t get damaged when exposed to the super-cooled liquid hydrogen at -423 degrees Fahrenheit.
NASA/Kim Shiflett “We tried everything we could think of,” Pavicic recalls. “Any procedure we could try, we tried it, and we just never saw those rates that we should have.”
Thus, Pavicic, who is originally from West Palm Beach and studied aerospace engineering at Embry Riddle Aeronautical University in Daytona Beach, Florida, went back to the drawing board with the rest of his team, working days and nights rewriting procedures and learning new lessons about the engines and sensors until they were finally able to get to a successful launch.
“I just remember after I said, 'NO-GO,' I felt like all these people came to watch the launch, all my family, and I'm like, ‘I'm the guy,' but I told myself, ‘I'm not going to be the one to say this for the next launch attempt. I'm going to do what I can to get us there.’

NASA successfully launched and flew the Artemis I mission and now, Pavicic is working as one of the operations project engineers, continuing to help the launch team develop new launch commit criteria and procedures within the launch countdown ahead of Artemis II, the first crewed Artemis mission, which will send four astronauts around the Moon and back in 10 days next year.

The SpaceX Dragon spacecraft carrying the Axiom Mission 4 crew launches atop the Falcon 9 rocket from NASA’s Kennedy Space Center to the International Space Station.Credit: NASA As part of NASA’s efforts to expand access to space, four private astronauts are in orbit following the successful launch of the fourth all private astronaut mission to the International Space Station.
A SpaceX Dragon spacecraft lifted off at 2:31 a.m. EDT Wednesday from Launch Complex 39A at NASA’s Kennedy Space Center in Florida, carrying Axiom Mission 4 crew members Peggy Whitson, former NASA astronaut and director of human spaceflight at Axiom Space as commander, ISRO (Indian Space Research Organisation) astronaut and pilot Shubhanshu Shukla, and mission specialists ESA (European Space Agency) project astronaut Sławosz Uznański-Wiśniewski of Poland and HUNOR (Hungarian to Orbit) astronaut Tibor Kapu of Hungary.
“Congratulations to Axiom Space and SpaceX on a successful launch,” said NASA acting Administrator Janet Petro. “Under President Donald Trump’s leadership, America has expanded international participation and commercial capabilities in low Earth orbit. U.S. industry is enabling astronauts from India, Poland, and Hungary to return to space for the first time in over forty years. It’s a powerful example of American leadership bringing nations together in pursuit of science, discovery, and opportunity.”
A collaboration between NASA and ISRO allowed Axiom Mission 4 to deliver on a commitment highlighted by President Trump and Indian Prime Minister Narendra Modi to send the first ISRO astronaut to the station. The space agencies are participating in five joint science investigations and two in-orbit science, technology, engineering, and mathematics demonstrations. NASA and ISRO have a long-standing relationship built on a shared vision to advance scientific knowledge and expand space collaboration.
This mission serves as an example of the success derived from collaboration between NASA’s international partners and American commercial space companies.
Live coverage of the spacecraft’s arrival will begin at 5 a.m., Thursday, June 26, on NASA+. Learn how to watch NASA content through a variety of platforms, including social media.
The spacecraft is scheduled to autonomously dock at approximately 7 a.m. to the space-facing port of the space station’s Harmony module.
Once aboard the station, Expedition 73 crew members, including NASA astronauts, Nicole Ayers, Anne McClain, and Jonny Kim, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonauts Kirill Peskov, Sergey Ryzhikov, and Alexey Zubritsky will welcome the astronauts.
The crew is scheduled to remain at the space station, conducting microgravity research, educational outreach, and commercial activities for about two weeks before a return to Earth and splashdown off the coast of California.
The International Space Station is a springboard for developing a low Earth economy. NASA’s goal is to achieve a strong economy off the Earth where the agency can purchase services as one of many customers to meet its science and research objectives in microgravity. NASA’s commercial strategy for low Earth orbit provides the government with reliable and safe services at a lower cost, empowers U.S. industry, and enables the agency to focus on Artemis missions to the Moon in preparation for Mars while also continuing to use low Earth orbit as a training and proving ground for those deep space missions.

NASA is preparing to make history by sending humans to the Moon’s South Pole. There, astronauts will conduct moonwalks for exploration, science experiments, and prepare humanity for the journey to Mars. Missions of this scale require extensive planning, especially when accounting for emergency scenarios such as a crew member becoming incapacitated.
To address this critical risk, the South Pole Safety Challenge invited the public to develop a compact, effective device capable of safely rescuing astronauts during emergency situations on the Moon’s surface. Given the harsh and unpredictable conditions of the lunar South Pole, the rescue system must be lightweight, easy to use, and able to transport an incapacitated crew member weighing approximately 755 lbs. (343 kg), representing the crew member and their suit, without the help of the lunar rover. It must also be capable of covering up to 1.24 miles (2 kilometers) across slopes as steep as 20 degrees.
“The initiative saved the government an estimated $1,000,000 and more than three years of work had the solutions been produced using in-house existing resources,” said Ryon Stewart, acting Program Manager of NASA’s Center of Excellence for Collaborative Innovation. “The effort demonstrated how crowdsourcing provides NASA with a wide diversity of innovative ideas and skills.”
The global challenge received 385 unique ideas from 61 countries. Five standout solutions received a share of the $45,000 prize purse. Each of the selected solutions demonstrated creativity, practicality, and direct relevance to NASA’s needs for future Moon missions.
