A Soyuz rocket launched two Galileo satellites into orbit on Friday, marking a crucial step for Europe’s planned navigation system, operator Arianespace announced.
The launch took place at the Kourou space base in French Guiana, at 3:15pm (6:15pm GMT).
Three and three-quarter hours later, the 700kg satellites were placed into orbit.

The new satellites add to the first two in the Galileo navigation system, which were launched on Oct. 21, last year.
Together they create a “mini-constellation.” Four is the minimum number of satellites needed to gain a navigational fix on the ground, using signals from the satellite to get a position for latitude, longitude, altitude and a time reference.
Galileo will ultimately consist of 30 satellites, six more than the US Global Positioning System.
By 2015, 18 satellites should be in place, which is sufficient for launching services to the public, followed by the rest in 2020, according to the European Space Agency.
It is claimed that the system will be accurate to within one meter. The US Global Positioning System, which became operational in 1995 and is currently being upgraded, is currently accurate to between three and eight meters.
In May, the European Commission said the cost by 2015 would be 5 billion euros (US$6.45 billion).
As a medium-sized launcher, Soyuz complements Europe’s heavyweight Ariane 5 and lightweight Vega rockets.
STEPPING UP: Diminished US polar science presence mean opportunities for the UK and other countries, although China or Russia might also fill that gap, a researcher said The UK’s flagship polar research vessel is to head to Antarctica next week to help advance dozens of climate change-linked science projects, as Western nations spearhead studies there while the US withdraws. The RRS Sir David Attenborough, a state-of-the-art ship named after the renowned British naturalist, would aid research on everything from “hunting underwater tsunamis” to tracking glacier melt and whale populations. Operated by the British Antarctic Survey (BAS), the country’s polar research institute, the 15,000-tonne icebreaker — boasting a helipad, and various laboratories and gadgetry — is pivotal to the UK’s efforts to assess climate change’s impact there. “The saying goes
Floods on Sunday trapped people in vehicles and homes in Spain as torrential rain drenched the northeastern Catalonia region, a day after downpours unleashed travel chaos on the Mediterranean island of Ibiza. Local media shared videos of roaring torrents of brown water tearing through streets and submerging vehicles. National weather agency AEMET decreed the highest red alert in the province of Tarragona, warning of 180mm of rain in 12 hours in the Ebro River delta. Catalan fire service spokesman Oriol Corbella told reporters people had been caught by surprise, with people trapped “inside vehicles, in buildings, on ground floors.” Santa Barbara Mayor Josep Lluis
Police in China detained dozens of pastors of one of its largest underground churches over the weekend, a church spokesperson and relatives said, in the biggest crackdown on Christians since 2018. The detentions, which come amid renewed China-US tensions after Beijing dramatically expanded rare earth export controls last week, drew condemnation from US Secretary of State Marco Rubio, who on Sunday called for the immediate release of the pastors. Pastor Jin Mingri (金明日), founder of Zion Church, an unofficial “house church” not sanctioned by the Chinese government, was detained at his home in the southern city of Beihai on Friday evening, said
TICKING CLOCK: A path to a budget agreement was still possible, the president’s office said, as a debate on reversing an increase of the pension age carries on French President Emmanuel Macron yesterday was racing to find a new prime minister within a two-day deadline after the resignation of outgoing French Prime Minister Sebastien Lecornu tipped the country deeper into political crisis. The presidency late on Wednesday said that Macron would name a new prime minister within 48 hours, indicating that the appointment would come by this evening at the latest. Lecornu told French television in an interview that he expected a new prime minister to be named — rather than early legislative elections or Macron’s resignation — to resolve the crisis. The developments were the latest twists in three tumultuous
