UDOM enhances rocket tech for rainmaking

DAR ES SALAAM: THE University of Dodoma (UDOM) has made notable advancements to a rocket system intended to deploy equipment into the atmosphere, aimed at facilitating artificial rainmaking in areas severely affected by extended dry spells and insufficient rainfall.

UDOM Senior Lecturer Dr Benatus Mvile revealed the development at the ongoing 49th Dar es Salaam International Trade Fair (DITF), noting it is part of the university’s efforts to create practical, low-cost solutions for smallholder farmers who can’t afford technologies like borehole drilling.

“This rocket supports weather modification by creating favourable conditions for rainfall and has the potential to benefit entire communities, especially those without access to irrigation infrastructure,” he said.

He noted that earlier versions of the rocket faced technical issues, particularly with flight stability and directional control.

“Last year, the rocket struggled to stay on course. We’ve since made significant upgrades, especially to the wings and nose structure, to improve aerodynamic performance and directional accuracy.”

According to Dr Mvile, the improvements involved modifying the fins and redesigning the nose cone, resulting in more stable test flights.

“We conducted several test launches after the modifications and the results are promising,” he said.

While the current version does not yet include equipment to measure speed and range, Dr Mvile noted that these features will be added in the next development phase once operational requirements are finalised.

“At this stage, the rocket functions as a delivery system, designed to carry instruments from the ground into the atmosphere,” he explained.

He added that the innovation comes at a critical time when climate change continues to disrupt weather patterns and impact food production and livelihoods across the country
