News: China launched the Tianhe module on the 29th April into orbit, which contains living quarters for crew members for a new space station which should be operational by 2022. The new, 66 tonne, multi-module is set to be operational for at least 10 years. Beijing plans to have at least 10 more similar launches, carrying all the additional equipment into orbit, before the completion of the station next year. It will orbit Earth at an altitude of 340 to 450km (210-280 miles) which is much the same as the ISS. The ISS is due to be retired after 2024, which could potentially leave Tiangong as the only space station in Earth's orbit. When the Tiangong is up and running, it will be only a quarter of the size of the ISS.
China and Russia have announced plans to build a lunar space station. It comes as Russia prepares to celebrate the 60th anniversary of its first-ever manned space flight. They will use their accumulated experience in space science, research and development and use of space equipment and space technology to jointly devlop a road map for the construction of an “international lunar scientific research station” the statement (in Mandarin) said.
On the 15th May China successfully landed a spacecraft on Mars. The six-wheeled Zhurong robot was targeting the region Utopia Planita, a vast terrain in the planet's northern hemisphere. Only the Americans have really mastered landing on Mars until now. All other countries that have tried have either crashed or lost contact soon after reaching the surface.
NASA's Osiris-Rex leaves asteroid Bennu, and heads for home. After five years on mission, including more than two years spent exploring the 500 metre asteroid 101955 Bennu Osiris-Rex fired its thrusters for 7 minutes on Monday 10th May. This burn set the spacecraft moving 600mph relative to the asteroid to start its 2½ year journey back to Earth.
Saturn is the only planet we know of whose magnetic field is almost exactly aligned with its axis of rotation. In a new analysis of data collected during the final orbits of the Cassini mission, astronomers propose the field's unique nature might come from a thick layer of helium ”rain” that's falling slowly onto the planet's mettalic hydrogen core.
In mid-May a star in the constellation of Cassiopeia that flared into view during mid-March has erupted to naked-eye visibility at 5.5 mag. The end two stars Schedar (2.2 mag) and Caph (2.2 mag) of the “W” shaped constellation point towards the Nova. The Nova is approximately 6 degrees from Caph.
Facts: China sent its first astronaut Yang Liwei (b.1965) into space in 2003 making it the third country to do so, after the Soviet Union and the United States.
