Ghanaians and Americans have jubilated over a spacecraft which landed in Mars.

On Monday, November 26, 2018, InSight, the spacecraft belonging to America's National Aeronautics and Space Administration (NASA) landed on Mars.

According to reports, the spacecraft is expected to study the Mars' underworld, listening for marsquakes and seeking clues about the dusty world’s formation.

Although the spacecraft belongs to the Americans, its (spacecraft) invention is due to a remarkable work of Ghanaian engineer Dr Ashitey Trebi-Ollennu who is the team lead for InSight at NASA's Jet Propulsion Laboratory.

Dr. Ashitey Trebi-Ollennu is the chief engineer of a team formed to design robots for NASA missions at the NASA Jet Propulsion Laboratory in La Cañada Flintridge, California and United States.

He has not only worked on the Phoenix aircraft that found water on Mars in 2008 but also, he contributed to the Mars Exploration Rover project in 2003 and the Mars Science Laboratory in 2011.

Dr. Trebi-Ollennu designed the robotic arm, which will dig deep beneath the surface of the planet to see explore how it was formed.

His desire to construct a spacecraft developed when he was growing up in Ghana.

This is due to an  because at the heart of the historic landing on Mars on Monday is the remarkable work of Ghanaian engineer Dr Ashitey Trebi-Ollennu who is the team lead for InSight at NASA's Jet Propulsion Laboratory.
