NASA robotic vehicle landing: An inspiration for African Unity

BY ARTHUR G O MUTAMBARA The US NASA Perseverance Rover safely landed on Mars on  February 18 2021 after a 470, 7million-kilometre-journey from Earth, which it began on  July 30 2020. The robotic vehicle landed itself flawlessly in Mars’ Jezero Crater. The scientific objectives 1) Search for, and identify, a past capable of microbial life, i.e, investigate the habitability of Mars. 2) Look for signs of current microbial life (biosignatures) in the places where the history of life is detected. 3) Note the distinction between microbial life and intelligent life (human-like life). The expectation (or assumption) is that there is no intelligent life elsewhere in the universe except on Earth. Of course, this is our shared human arrogance as a species. 4) Collect rock and soil samples, analyse them on site and bring some to Earth for further studies about Mars’s mineralisation, geography, habitability etc. No surprises on who will own the minerals if they are discovered! 5) Prepare Mars for the landing and then habitation by humans. For example, on the Rover, there is equipment to produce oxygen from Mars’ atmosphere, which consists mainly of carbon dioxide. No surprises on who will colonise the planet if it is made habitable! The technology involved The Perseverance Mars Rover is a six-wheeled mobile robot with the following technologies: 1) Multiple sensors such as super-cameras, imagers and radar. 2) Intelligent sensor fusion and control — to interpret the various sensor information and use the outcome to direct the Rover’s movement. 3) Six wheel mobile robotic technology for navigating the rough, rugged and unpredictable Martian terrain. 3) Robotic arm for collecting samples and manipulating objects on the surface of Mars. 4) An ultraviolet spectrometer and an X-ray spectrometer for on-site analysis of collected soil and rock samples. 5) MEDA — A mounted weather station on the Rover. 6) MOXIE — Technology to produce oxygen from carbon dioxide, which is the dominant gas in the Martian atmosphere. 7) Mini-helicopter drone — A solar-powered experimental aircraft to test flight stability and scout driving routes for Rover. Why space exploration? Are we not wasting resources by pursuing such grand scientific projects? Well, human curiosity will continue to exist in the midst of poverty, disease, inequality or war. Those with the cash will use their resources to address to explore, experiment and venture into the unknown. What will be prudent is to pursue a multipurpose agenda where science is used to address curiosity but also to solve existing problems. More importantly, the science and technology developed from the pursuit of curiosity (such as space exploration) can be applied to solve urgent and pressing human problems. It is a dynamic process Given the negative experiences (to Africans and others) of past voyages and discoveries, this plunge into space exploration should be cooperative. However, no one will involve the African if we do not pull our resources together and assert agency as a united and integrated continen
