On Tuesday, August 7th at 1:18 a.m. EDT, Falcon 9 successfully lifted off from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida carrying the Merah Putih mission for PT Telkom Indonesia. The satellite was deployed approximately 32 minutes after liftoff into its targeted Geostationary Transfer Orbit (GTO).Read More
Pummeling the ground with an estimated 2.5 million pounds (1.1 million kg) of thrust, the largest and most powerful member of United Launch Alliance’s (ULA) Atlas V fleet roared aloft earlier tonight (Saturday, 14 April), to deliver a multi-purpose payload into orbit on behalf of the U.S. Air Force Space Command. Liftoff of the Atlas V 551—equipped with a 17-foot-wide (5-meter) payload fairing, five strap-on solid-fueled rockets and a single-engine Centaur upper stage—occurred from Space Launch Complex (SLC)-41 at Cape Canaveral Air Force Station, Fla., at 7:13 p.m. EDT, right on the opening of tonight’s two-hour “window”...Read More
This time-lapse video shows the ATV-5 Georges Lemaitre loading process and its integration on the Ariane 5 launcher before its transfer and launch to the International Space Station from Europe’s Spaceport in Kourou, French Guiana on 29 July 2014.
On August 22, 2014, at 9:27 am local time in French Guiana, a Soyuz ST rocket lifted off with the first two satellites in the Galileo constellation.
The liftoff and first part of the mission proceeded nominally, leading to release of the satellites according to the planned timetable, and reception of signals from the satellites. It was only a certain time after the separation of the satellites that the ongoing analysis of the data provided by the telemetry stations operated by the European Space Agency (ESA) and the French space agency CNES showed that the satellites were not in the expected orbit.
On 22 August, at 12:27 GMT/14:27 CEST, a Soyuz rocket launched Europe’s fifth and six Galileo satellites from Europe’s Spaceport in Kourou, French Guiana. Rewatch the moment of launch here. These new satellites joined four Galileo satellites already in orbit, launched in October 2011 and October 2012 respectively. This first quartet were ‘In-Orbit Validation’ satellites, serving to demonstrate the Galileo system would function as planned.Read More
Timelapse showing the Orbital Science’s Cygnus Orb-2 spacecraft departing from the International Space Station on 15 August 2014. ESA astronaut Alexander Gerst set up a camera to shoot a series of photographs whilst he and his Expedition 40 colleague NASA’s Reid Wiseman operated the Station’s robotic arm to manoeuvre the visiting cargo spacecraft into position for release. A couple of days later, Cygnus Orb-2 burnt up in Earth’s atmosphere during a destructive reentry.Read More
Nestled within the shell around this large bubble is an embryonic star that is already a hefty eight times more massive than our Sun.
This image, by ESA’s Herschel space observatory, was originally presented in the first announcement of scientific results from the mission in May 2010.
This week Herschel scientists will meet again at ESA’s ESTEC establishment in the Netherlands to present, discuss, and take stock of the scientific breakthroughs of the entire mission at The Universe Explored by Herschel symposium.
The Galactic bubble shown in this image was just one of many surprising results of the mission.
It is about 4300 light-years away and has been blown by a star at its centre...Read More
After nearly tripling its planned lifetime, the Gravity field and steady-state Ocean Circulation Explorer – GOCE – is nearing its end of mission and will soon reenter our atmosphere.
With a sleek, aerodynamic design responsible for it being dubbed the ‘Ferrari of space’, GOCE has mapped variations in Earth’s gravity with extreme detail. Scientists further exploited these data to create the first global high-resolution map of the boundary between Earth’s crust and mantle – called the Moho – and to detect sound waves from the massive earthquake that hit Japan on 11 March 2011, among other results.
In mid-October, the mission will come to a natural end when it runs out of fuel and the satellite begins its descent towards Earth from a height of about 224 km.Read More
ESA’s test rover has been fitted with scientific instruments and made its first tracks in the sands of Chile’s Atacama Desert. Meanwhile, team members have explored the area to select a suitable site for testing, flying a drone to produce an aerial map.
This week’s Sample Acquisition Field Experiment with a Rover, or SAFER, field trial is gaining experience in remotely operating a Mars rover prototype equipped with scientific instruments.
ESA has assembled an international industrial team for the trial, which takes place in the Mars-like Atacama, one of the driest places on Earth.
“During the past few days we have been busy preparing for the actual trial,” explains Michel van Winnendael, overseeing the testing for ESA...Read More
A mystery that has stumped scientists for decades might be one step closer to solution after ESA tracking stations carefully record signals from NASA’s Juno spacecraft as it swings by Earth today.
NASA’s deep-space probe will zip past to within 561 km at 19:21 GMT as it picks up a gravitational speed boost to help it reach Jupiter in 2016.
During the high-speed event, radio signals from the 3225 kg Juno will be carefully recorded by ESA tracking stations in Argentina and Australia.
Engineers hope that the new measurements will unravel the decades-old ‘flyby anomaly’ – an unexplained variation in spacecraft speeds detected during some swingbys.
“We detected the flyby anomaly during Rosetta’s first Earth visit in March 2005,” says Trevor Morley, flight dynamics expert at ESA’s ESOC...Read More
