![]() Currently, three astronauts are on a six-month trip to the space station to monitor the completion of its construction. By the end of the year, the basic construction is anticipated to be finished. MFHvMx89DUĪccording to the official Chinese news agency Xinhua, the lab-sized optical clock created for Tiangong had to be more than 20 times smaller to fit on the experiment rack of the space station.Ĭhina sent the first module of its space station into orbit last year, and it has plans to launch other modules. Ye said, adding that his team had no intention of sending their clock to a space station because of the difficulties in realizing a tiny size and reliable operation.įrom his basement lab in Boulder, Colorado, physicist Jun Ye and his team have built the world’s most precise atomic clock. He claimed that building optical clocks for use in a lab was very different from developing smaller, lighter ones for use in space. Jun Ye, a physicist at the University of Colorado Boulder and the US National Institute of Standards and Technology, described that level of uncertainty as “amazing.” ![]() The Chinese space station manual and international collaboration resources state that the clock’s goal uncertainty in orbit is also 10-18. Satellite navigation and internet time are impossible without atomic clocks- Science Photo Library.Īccording to the National Time Service Centre website, testing on the ground started in late April. However, the team is still awaiting the results of a crucial test to determine how well it would function in space. Positioning can be incorrect by more than one meter with a timing error of just a few billionths of a second.Īccording to the scientist associated with the project, the Chinese atomic clock has already attained quintillionth-second precision, or 10-18 uncertainty in technical words on the ground. It potentially indicates that the “precision clock” would have a dual-use purpose which makes sense given the rapid militarization of space by major space powers.Īdvanced missiles, sensors, aircraft, ships, and artillery use atomic clocks aboard GPS satellites to provide nanosecond timing accuracy. In addition to facilitating quicker communications and improved navigation, optical atomic clocks are crucial for maintaining national security. The optical atomic clock could be a game-changer for military and civilian applications because it is intended to achieve the precision of one quintillionth of a second, comparable to losing or gaining one second every 30 billion years, Hong-Kong-based South China Morning Post reported.Ītomic clocks are timepieces that monitor the resonance of atom frequencies, often cesium or rubidium atoms which allows these clocks to measure time quite precisely. In what could be another milestone for the Chinese Space Station and its space agency, Tiangong could soon have the most ‘precise clock’ in orbit if it passes a technical test scheduled for the following week, according to an unnamed scientist familiar with the project.

China is set to make history when it finally completes the construction of its Space Station ‘Tiangong’ and makes it operational this year.
