1.Square Kilometre Array (SKA)

The international science and engineering project - the Square Kilometre Array (SKA) project is the world largest aperture synthesis radio telescope planned by the international astronomical community, giving great opportunities to explore the universe. SKA is well related to a number of cutting-edge fields including astronomy, radio, information technology, computer science, green energy and so on. Governments and research institutions from many countries are jointly preparing and participating in the project. In September 2012, the State Council approved that the Ministry of Science and Technology will participate on behalf of China in the pre-construction development stage of SKA. SKA covers a great number of fundamental research and high technology areas, which is the second international science and engineering project that our country participates as an official member following the project of International Thermonuclear Fusion Reactor (ITER). The headquarter of SKA is in the United Kingdom.

2. The Discovering the Sky at the Longest Wavelengths (DSL)

The Discovering the Sky at the Longest Wavelengths (DSL) aims at building up a space telescope array (frequency range 0.1 - 30 MHz) that serves multiple science discovery/exploration purposes. This mission will set up a satellite constellation containing/including one mother-ship and eight daughter-ship satellites in lunar orbit or at the second Lagrangian point L2 at the distance of 1,500,000 kilometers from the earth. The radio quietness of the Moon’s far-side and L2 provides excellent/ideal condition for low-frequency observation. Each mini-satellite is equipped with an omnidirectional antenna for observation, and the eight combined together form an interference synthetic aperture array. The mother-ship satellite is larger in size and is responsible for tasks including on-board data ingesting, digital signal processing, satellite constellation control, inter-satellite communication and satellite-to-ground communication. This mission will for the first time photograph cosmic images at the longest wavelengths and also at the last unexploited frequency range, opening a new window for exploring the universe and introducing a brand new cognitive domain.

3.Space decimeter VLBI Plan(ROSE)

The mission plans to launch a 30meter-diameter radio telescope into a 36000km elliptical orbit, and works together with the unprecedented ground-based network to get very high resolution and very high sensitivity. The ROSE is operated at decimeter and long centimeter, and aims to achieve a maximum of 0.1 milli-arcsecond angular resolution and less than 0.1 milli-Jy sensitivity, filling the gap of the research on radio faint source Very Long Baseline Interferometry (VLBI) imaging. The scientific objectives include: investigating supermassive black holes in the early universe, tracing the cosmic star formation history, exploring the co-evolution of supermassive black hole and its host galaxy in cosmological scale, gravitational wave and so on.
