The European Space Agency (ESA) is doing its part to help protect the planet from any asteroid that could threaten life on earth by awarding a euro 129.4 million (US $153 million) contract to an industrial consortium led by the German space company OHB. The mission, named after the Greek goddess of marriage and stove, will complement NASA’s dual asteroid redirection test mission and help provide a way for future planetary defense operations. < / P > < p > ESA’s Hera mission will launch a table sized satellite, which itself will contain small cubesats, to post impact assess the impact of NASA’s dart spacecraft on asteroids. It is designed to be based on High-speed Impact spacecraft, with the aim of autonomous navigation around small planets and collecting data to help scientists on earth understand them Whether or not the ambitious plan to use a man-made spacecraft to deliberately impact an asteroid and change its trajectory in space. After deployed from the Hera spacecraft, cubesats will conduct close range exploration of asteroids, including a potential internal detector with radar array, which is the first of its kind for small asteroids. Hera and her cubesats companions will spend six months studying asteroids in conjunction with the dual asteroid redirection test (DART). The NASA mission will be launched sometime in July 2021 and will arrive at the asteroid known as Didymos in September the following year. The ESA mission is expected to launch in October 2024 and rendezvous with asteroids in 2026. Didi Qingju bicycle has entered 150 cities
