EU warns 3 countries of legal action over refugee plan

  EU warns 3 countries of legal action over refugee plan The European Union warned the Czech Republic, Hungary and Poland on Tuesday that they have 24 hours to start taking in refugees.But the three countries immediately rebuffed the threat and appeared ready to go to court.

After 17 years and numerous setbacks and budget boosts, Europe ' s Galileo satnav system is due to go live on Thursday with promises of better-than-ever location services. The ExoMars Trace Gas Orbiter has returned the first images of the Red Planet from its new orbit.

The European Space Agency signed a contract with a German-British consortium Thursday to build eight more satellites for its Galileo satnav system, an alternative to America's GPS, the agency said Thursday.

The deal was signed at the International Paris Air Show with German company OHB as the prime contractor, and Surrey Satellite Technology Ltd in charge of navigation systems.

The ESA signed on behalf of the European Commission, which owns and funds the system.

"Europe's Galileo navigation constellation will gain an additional eight satellites, bringing it to completion," the ESA said in a statement.

Rome seeks migrant moratorium, warns of social tensions

  Rome seeks migrant moratorium, warns of social tensions Rome's populist mayor called Tuesday for a moratorium on new migrants arriving in the city, warning that setting up additional reception centres risked sparking explosive social tensions in the capital. In the most significant challenge yet to the centre-left Italian government's policy of distributing across the country the thousands of migrants arriving at southern ports, Virginia Raggi said it was "time to listen to the citizens of Rome.""We cannot permit the creation of more social tensions," Raggi, a member of the populist Five Star Movement, wrote on her Facebook page.

Eighteen Galileo satellites have been placed in Earth's orbit to date, with four more due for launch later this year.

With the last eight satellites to be built and tested by OHB, the 10-billion-euro ($11-billion) constellation will ultimately comprise 30 orbiters.

Twenty-four will be operational, in three orbital planes, with the rest standing by as spares, in orbit and on the ground.

The European Commission expects Galileo to be fully operational by 2020.

The project has experienced many setbacks, including the placement of two satellites in the wrong orbit.

Galileo went live in December last year, providing initial services with a weak signal, having taken 17 years and more than triple the original budget.

The civilian-controlled service is seen as strategically important for Europe, which relies on two military-run rivals -- GPS and Russia's GLONASS.

New orbiters for Europe ' s Galileo satnav system . Europe ' s beleaguered Galileo satnav has suffered another setback, with clocks failing onboard a number of satellites in space, the European Space Agency said Wednesday.

Neither provides a guarantee of uninterrupted service.

In January, ESA said the system suffered another setback, with atomic clocks -- claimed by the agency to be the most accurate ever flown for geolocalisation -- failing onboard a number of satellites in space.

Each Galileo satellite has four ultra-accurate atomic timekeepers, but needs just one working clock.

The failure of nine clocks out of 72 launched so far, has not affected operation, the agency said at the time.

But it would necessitate a relook at clock design, meaning further possible delays.

Thursday's statement said the eight new satellites are based on the approved design for the previous ones, but will feature "improvements based on lessons learnt."

Once fully deployed, Galileo aims to pinpoint a location on Earth to within a metre -- compared to several metres for GPS and GLONASS.

Clients of a paying service can get even more accurate readings -- down to centimetres.

It will also offer search-and-rescue services.
