China launched a high-resolution Earth-observation satellite from the Jiuquan Satellite Launch Center in Northwest China on Tuesday to improve its ocean surveillance capability.
The Gaofen 3-02 satellite was launched by a Long March 4C carrier rocket at 7:45 am and entered a sun-synchronous orbit at an altitude of 755 kilometers, the China National Space Administration said.

During the last seven years that I have operated spacecraft both in orbit and on the surface of Mars, I've come back again and again to the question of who is most responsible for making a spacecraft go.

Astronomers at the University of Copenhagen's Cosmic Dawn Center have discovered two previously invisible galaxies 29 billion light-years away. Their discovery suggests that up to one in five such distant galaxies remain hidden from our telescopes, camouflaged by cosmic dust. The new knowledge changes perceptions of our universe's evolution since the Big Bang.

NASA's Curiosity rover captured a remarkable image from its most recent perch on the side of Mars' Mount Sharp. The mission team was so inspired by the beauty of the landscape, they combined two versions of the black-and-white images from different times of the day and added colors to create a rare postcard from the Red Planet.
