作为国家在科学技术方面的最高学术机构和全国自然科学与高新技术的综合研究与发展中心,建院以来,中国科学院时刻牢记使命,与科学共进,与祖国同行,以国家富强、人民幸福为己任,人才辈出,硕果累累,为我国科技进步、经济社会发展和国家安全做出了不可替代的重要贡献。
中国科学 :技术大学(简称“中科大”)于1958年由中国科学院创建于北京,1970年学校迁至安徽省合肥市。中科大坚持“全院办校、所系结合”的办学方针,是一所以前沿科学和高新技术为主、兼有特色管理与人文学科的研究型大学。
中国科学院大学 (简称“国科大”)始建于1978年,其前身为中国科学院研究生院,2012年经教育部批准更名为中国科学院大学。国科大实行“科教融合”的办学方针,与中国科学院直属研究机构在管理体制、师资队伍、培养体系、科研工作等方面高度融合,是一所以研究生教育为主的独具特色的高等学校。
上海科技大学 (简称“上科大”),由上海市人民政府与中国科学院共同举办、共同建设,2013年经教育部正式批准。上科大秉持“服务国家发展战略,培养创新创业人才”的办学方针,实现科技与教育、科教与产业、科教与创业的融合,是一所小规模、高水平、国际化的研究型、创新型大学。

This is what the Laser Interferometer Space Antenna observatory might look like.
Hunting for gravitational waves, faint disturbances in the curvature of space-time, is not easy. Researchers have to wait for extreme cosmic events -- like a black hole collision -- and use ground-based lasers at the LIGO facilities in the US and the Virgo facility in Italy to detect the ripples in space-time they emit. But in the future, a system of space lasers will be established in orbit around the sun, giving astronomers a brand-new, ultra-sensitive pair of eyes.
The new project is a collaboration between the European Space Agency (ESA) and NASA known as the Laser Interferometer Space Antenna. The LISA mission is set to establish three laser-emitting spacecraft arranged in a triangle formation, maintaining a strict distance between each other of a casual 2.5 million kilometers apart. The lasers bounce around and create a signal, or interference pattern, and when a gravitational wave passes through the laser, the pattern changes.
Detect a pattern change? Boom -- you've just detected your first gravitational wave. Congratulations.
The Earth is a particularly noisy place, making it hard to detect the full range of cosmic events that cause gravitational waves. As a result, some of the most common events scientists believe will cause the ripples are invisible to us down here on the ground.
In space, that changes. With LISA we may detect black holes orbiting supermassive black holes and distant events stretching further back through space-time. However, building a space laser system is complicated. It has to withstand the hostile space environment and it has to remain incredibly accurate while it travels, in a triangle formation, around the sun.
Researchers at the Swiss Center for Electronics and Microtechnology have unveiled details of a prototype laser that meets "nearly all of the requirements outlined by ESA and NASA" and is compatible with space. They tested their prototype in a specialized test station and concede that it's not quite perfect -- but they're identifying the problems with their system and thinking about how it could be improved.
Fortunately, there's plenty of time before LISA gets into space.
"While a launch date shortly after 2030 might appear far away, there is still substantial technological development to be performed. The team is ready to further contribute to this exciting endeavor," said Steve Lecomte, a researcher at CSEM, in a press release.
More details about the prototype's performance will be detailed at The Optical Society's 2019 Laser Congress from Sept. 29 to Oct. 3. The words "Laser Congress" are enough to get me excited, so sign me up.
