Twenty-two years after putting the first African satellite into orbit, the continent's satellite fleet currently stands at 44. With Africa's most recent satellite launch taking place in June 2021, the next few years may see more launches on the continent.
The consultancy Space in Africa recently reported that 44 satellites have been sent into orbit by 13 African countries since the launch

Engineering researchers have developed a method to use signals broadcast by Starlink internet service satellites to accurately locate a position here on Earth, much like GPS does. It is the first time the Starlink system has been harnessed by researchers outside SpaceX for navigation.

Forests, especially tropical rainforests, are guardians against climate change. But our forests are burning. They are withering and dwindling. Our guardians are themselves threatened by climate change. A new European Space Agency (ESA) satellite mission, currently being built by Airbus, is set to investigate exactly how our forests are faring. The name says it all: Biomass.

The Moon is a cold, dry desert. Unlike the Earth, it is not surrounded by a protective atmosphere and water which existed during the Moon's formation has long since evaporated under the influence of solar radiation and escaped into space. Nevertheless, craters and depressions in the polar regions give some reason to hope for limited water resources. Scientists from MPS, the University of Oxford

The interiors of Uranus and Neptune each contain about 50,000 times the amount of water in Earth's oceans, and a form of water known as superionic water is believed to be stable at depths greater than approximately one-third of the radius of these ice giants.
