At 11.16 a.m. on October 14, 1999, China successfully delivered the remote sensing satellite No. 1 Earth Resources jointly developed by China and Brazil into the planned orbit using the “Long March IV B” carrier rocket at the Taiyuan Satellite Launch Center. A Brazilian small-scale scientific application satellite is also equipped with a lift-off. This is the first cooperation between China and Brazil in space technology. Resource 1, jointly developed by the China Academy of Space Technology and the National Space Academy of Brazil, has a total mass of 1540 kg. The satellite has a rectangular shape with single-wing solar panels with a power of 1100 W and a height of 778 km (near polar synchronous orbit
