Tianwen-1 is a much more ambitious spacecraft, an orbiter equipped with state-of-the-art remote sensing instruments and a small lander that’s expected to carry a six-wheel rover to the surface in May. Chinese news agencies did not carry the Mars orbit insertion burn live, but they confirmed success a few minutes after the fact.
Tianwen-1 and Hope have joined a fleet of eight other operational spacecraft in and around Mars, including NASA’s InSight lander, the Curiosity rover and six other orbiters, three sent by NASA, two by the European Space Agency and one from India.
