Photos: Ariane 5 rocket rolls to launch with four Galileo satellites
An Ariane 5 rocket emerged from its vertical assembly building Monday and rolled along dual rail tracks for a 1.7-mile (2.7-kilometer) journey to its launch pad at the Guiana Space Center on the northern coastline of South America, moving into position for blastoff Wednesday with four Galileo navigation satellites.
Ariane 5 rocket, Galileo satellites on launch pad in French Guiana
Ground crews in French Guiana on Monday transferred an Ariane 5 rocket to its launch pad, moving the vehicle into position for liftoff Wednesday with four European Galileo navigation satellites on the Ariane 5's last flight with an older-generation, out-of-production upper stage.
VideoPowerful new European solid-fueled rocket motor aces first test-firing
European engineers test-fired the world's most powerful present-day single-segment solid rocket booster Monday in French Guiana, clearing a major development hurdle for the Vega-C and Ariane 6 launchers set for debuts in 2019 and 2020.
Arianespace aims for busy second half of 2018
Europe's first mission to Mercury, a quartet of Galileo navigation spacecraft, the world's first global winds observatory, and a new European weather satellite have arrived at an equatorial launch base in French Guiana in preparation for launches in the coming months.
Webb’s launch delayed to 2021 at an extra cost of nearly $1 billion
An independent panel has informed NASA that the James Webb Space Telescope will not be ready for launch until March 2021, and Congress will have to reauthorize the long-delayed, over-budget mission after breaching an $8 billion cost cap, officials said Wednesday.
JWST beset by another problem as Northrop Grumman revamps training
Engineers working on the James Webb Space Telescope, which had its launch delayed to 2020 earlier this year, recently discovered another problem during testing at the observatory's prime contractor Northrop Grumman in Southern California.
Concerns with Indian satellite postpone next Ariane 5 launch
India's most powerful communications satellite will soon be flown back to its manufacturing plant in Bangalore for additional checks, officials said this week, forcing Arianespace to scrap plans for an Ariane 5 launch in late May that was to be co-manifested with a U.S.-built television broadcast satellite for Intelsat and the government of Azerbaijan.
Spaceflight reserves two rideshare missions on Vega rocket
Spaceflight Industries has booked reservations for two commercial rideshare missions on Arianespace's Vega rocket, officials announced Tuesday, beginning with a proof-of-concept flight in early 2019 of a new Italian-built multi-payload dispenser tailored to accommodate small satellites and CubeSats seeking a ride into orbit.
Ariane 5 returns to service with dual-satellite launch
Boosted by two solid-fueled motors and a hydrogen-burning main engine, a European Ariane 5 rocket took off Thursday from French Guiana with a Japanese military communications payload and a U.S.-built, British-owned broadband satellite, returning to service after a January mission placed two spacecraft in the wrong orbit.
Video: Ariane 5 rocket lifts off with communications satellites
A European Ariane 5 rocket climbed off its launch pad in French Guiana with nearly 3 million pounds of thrust Thursday, carrying two communications satellites to orbit for the Japanese military and British-based Avanti Communications.
