China would lose access to a strategic space tracking station in Western Australia when its contract expires, the facility’s owners said, a decision that cuts into Beijing’s expanding space exploration and navigational capabilities in the Pacific region.
The Swedish Space Corp (SSC) has had a contract allowing Beijing access to the satellite antenna at the station since at least 2011.
The station is located next to an SSC satellite station primarily used by the US and its agencies, including NASA.
The Swedish state-owned company said it would not enter into any new contracts at the Australian site to support Chinese customers after its current contract expires.
However, it did not disclose when the lease runs out.
“Given the complexity of the Chinese market, brought about by the overall geopolitical situation, SSC has decided to focus mainly on other markets for the coming years,” it said in an e-mailed response to questions.
The site is owned by SSC subsidiary SSC Space Australia.
Neither the Australian government nor the Chinese Ministry of Foreign Affairs responded yesterday to requests for comment.
The expansion of China’s space capabilities, which includes the growing sophistication of its Beidou navigation network, is one of the new frontiers of tension between the US and China.
Australia has a strong alliance with the US, which includes working together on space research and programs, while Canberra’s diplomatic and trade ties with Beijing have been fracturing.
China last used the Yatharagga Satellite Station, located about 350km north of Perth, in June 2013 to support the three-person Shenzhou 10 mission, which completed a series of space docking tests, SSC said.
The SSC said the current contract supports Chinese missions within its program for manned-space flights for telemetry, tracking and command services.
While ground stations have different capabilities, they can be equipped to co-ordinate satellites for civil-military global navigation satellite systems (GNSS) such as BeiDou, Russia’s GLONASS, the EU’s Galileo system and US-owned GPS.
China’s space program has been increasing its access to overseas ground stations in recent years as part of the expansion of its space and navigational programs.
“Generally speaking anywhere you put a GNSS monitoring ground station will improve the accuracy of positioning for that region,” said Joon Wayn Cheong, a senior research associate at the University of New South Wales’ School of Electrical Engineering.
Christopher Newman, a professor of space law and policy at Northumbria University in England, said China wants to remove its dependence on GPS as part of broader plans to expand its global influence.
Two former Chilean ministers are among four candidates competing this weekend for the presidential nomination of the left ahead of November elections dominated by rising levels of violent crime. More than 15 million voters are eligible to choose today between former minister of labor Jeannette Jara, former minister of the interior Carolina Toha and two members of parliament, Gonzalo Winter and Jaime Mulet, to represent the left against a resurgent right. The primary is open to members of the parties within Chilean President Gabriel Boric’s ruling left-wing coalition and other voters who are not affiliated with specific parties. A recent poll by the
TENSIONS HIGH: For more than half a year, students have organized protests around the country, while the Serbian presaident said they are part of a foreign plot About 140,000 protesters rallied in Belgrade, the largest turnout over the past few months, as student-led demonstrations mount pressure on the populist government to call early elections. The rally was one of the largest in more than half a year student-led actions, which began in November last year after the roof of a train station collapsed in the northern city of Novi Sad, killing 16 people — a tragedy widely blamed on entrenched corruption. On Saturday, a sea of protesters filled Belgrade’s largest square and poured into several surrounding streets. The independent protest monitor Archive of Public Gatherings estimated the
Irish-language rap group Kneecap on Saturday gave an impassioned performance for tens of thousands of fans at the Glastonbury Festival despite criticism by British politicians and a terror charge for one of the trio. Liam Og O hAnnaidh, who performs under the stage name Mo Chara, has been charged under the UK’s Terrorism Act with supporting a proscribed organization for allegedly waving a Hezbollah flag at a concert in London in November last year. The rapper, who was charged under the anglicized version of his name, Liam O’Hanna, is on unconditional bail before a further court hearing in August. “Glastonbury,
The Vatican Museums on Thursday unveiled the last and most important of the restored Raphael Rooms, the spectacularly frescoed reception rooms of the Apostolic Palace that in some ways rival the Sistine Chapel as the peak of high Renaissance artistry. A decade-long project to clean and restore the largest of the four Raphael Rooms uncovered a novel mural painting technique that Renaissance painter and architect Raphael began, but never completed. He used oil paint directly on the wall, and arranged a grid of nails embedded in the walls to hold in place the resin surface onto which he painted. Vatican Museums officials
