Two hot-air balloons, which will overfly Kilimanjaro collecting scientific data for climate research, were expected to take off on Tuesday.
The expedition was delayed because of unfavourable weather conditions. A week after the arrival of Swiss scientists and pilots, the balloons were due to lift off in the morning.
The two-week project launched by the Swiss company Balloon Team involves using an aerostat to fly over the Tanzanian volcano, where scientists will study aerosols, small particles, and their effect on climate and health.
One of the main challenges the Balloon Team faces are the meteorological conditions.
Because of Kilimanjaro's proximity to the Equator, the pilots could struggle with the lack of wind.
