About the ARLISS Competition

The ARLISS 2021 event is an opportunity for universities around the world to participate in several different competitions. The event, which spans over several days, was held from September 8-12 at Black Rock, Nevada. Windward Community College (WinCC) and Honolulu Community College (HonCC) participated in the hydbrid-motor competition. The hybrid motor was powered with liquid nitrous oxide and a proprietary solid fuel. The WCC team collaborated with HonCC, which designed an atmospheric sampling payload. The Project Imua Mission 9 team won first place in the Extreme Altitude Hybrid Motor competition with the launch of their 12-foot, eight-inch hybrid rocket, named “Apophis” after the Egyptian god of chaos. In addition, two WCC students (Nikki Arakawa and Quinn O’Malley) took second place in the Extreme Altitude Contest for their class H and I solid rockets, respectively, launched at the AERO-PAC competition. The team took First Place in this event.

Windward CC graduate and UH Mānoa physics student Jared Estrada has been involved with Project Imua since 2019 and served as project lead for the Mission 9 rocket. The Project Imua team composed of 17 students and six mentors worked on the project for two years, due to pandemic related delays and cancellations.

A team of students from multiple University of Hawaii campuses took first place in a rocketry competition held in Nevada in September. The UH Community Colleges’ Project Imua Mission 9 team won the extreme altitude hybrid motor competition with the launch of their 12-foot, eight-inch hybrid rocket, named “Apophis” after the Egyptian god of chaos.

Students from Windward Community College originally designed and built this rocket for the Spaceport America Cup’s competition sponsored by the Experimental Sounding Rocket Association that was to be held during the summer in New Mexico, but was canceled due to the COVID-19 pandemic. Honolulu Community College students designed an atmospheric sensing payload to be carried aboard Apophis.

The rocket and payload were finally launched in September 2021 in Black Rock, Nevada as part of the Association of Experimental Rocketry of the Pacific (AERO-PAC)’s competition. The Project Imua team won the altitude contest for the hybrid-motor class rockets after Apophis attained an apogee of 3,413 feet.

“I had actually never launched anything that big, so it was just so exciting to see it lift off the ground, go really high and then land as expected,” said UH Manoa College of Engineering student Nikki Arakawa.

Windward CC rocketry team members Arakawa and Quinn O’Malley also each placed second in the Extreme Altitude Contest for the solid rockets (in different classes) that each built and launched at the AERO-PAC competition.

Windward CC graduate and UH M?noa physics student Jared Estrada has been involved with Project Imua since 2019 and served as project lead for the Mission 9 rocket.

“People should know that it is a great opportunity to get hands-on experience in rocketry,” Estrada said. “It is an amazing opportunity and the team is very passionate and dedicated with what they do.”

The Project Imua team composed of 17 students and six mentors worked on the project for two years, due to pandemic related delays and cancellations.

“Our students learn first hand that rocket science is more than high tech and engineering,” said Project Imua Manager and Windward CC Professor Joe Ciotti. “‘To boldly go’ demands unwavering commitment, resilience and teamwork. The lessons learned on this mission will launch them on exciting careers.”

The two campuses are currently collaborating on Project Imua Mission 10 to develop a scientific payload that will be launched into sub-orbital flight this summer from NASA's Wallops Flight Facility in Virginia. This will be Project Imua’s fourth payload launched into outer space. Mission 10 is funded by the Hawaii Space Grant Consortium.
