How Earth's magnetic field is changing

The European Space Agency (ESA) launched its trio of Earth-facing satellites – the Swarm satellites – more than two years ago. Since then, the three probes have been tirelessly making measurements of the Earth's magnetic field, mapping it out in detail. Now, that data has been used in a new study of how the magnetic field has changed over recent years, with the results echoing what's happening at the planet's core. Read More

Lilium electric jet: VTOL air travel for the masses?

Can't face the drive to the airport? Why not bypass the whole circus and jump in your two-seat, vertical take-off and landing all-electric engine jet aircraft? That's the vision for the Lilium Jet, an aircraft currently being developed in Germany under the auspices of the European Space Agency's business incubation center that boasts fly-by-wire joystick controls, retractable landing gear, gull-wing doors, and a claimed top speed of 400 km/h (250 mph). The creators claim that this personal e-jet could be made available to the public as early as 2018.Read More

British astronaut pilots earthbound rover from aboard ISS

Deep space exploration has taken one small step (or roll) forward with the successful test of space-based control of a robot rover from aboard the International Space Station. The experiment saw British ESA astronaut Tim Peake take control of a British-built rover named "Bridget" and guide it around a simulated Martian landscape back on Earth, avoiding obstacles and locating scientific targets along the way.Read More

Study of Titan sea reveals unexpected composition

We've known for more than a decade that the largest of Saturn's moons plays hosts to lakes and seas of liquid hydrocarbons, but the exact make-up of these reservoirs has remained a mystery. Until now that is, with scientists from the European Space Agency (ESA) using data from eight years worth Cassini flybys to confirm that Ligeia Mare – one of the largest seas on the moon – is made up largely of liquid methane.Read More

ExoMars opens its eyes en route to the Red Planet

ESA has confirmed that the ExoMars 2016's Trace Gas Orbiter (TGO) mothership has opened its "eyes" and sent back its first test images. Launched on March 14 from the Baikonur cosmodrome in Kazakhstan, the joint ESA/Roscosmos mission to Mars was over 83 million km from Earth on April 7 when it transmitted a picture of random section of sky near the southern celestial pole as part of its commissioning process.Read More

Hubble zooms in on galactic core

A new Hubble image has presented a stunning glimpse of the nuclear star cluster known to shroud Sagittarius A* (Sgr A*) – the supermassive black hole that lurks at the heart of our galaxy. The spectacular 50 light-year wide image was captured in the infrared spectrum by Hubble's Wide Field Camera 3.Read More

ESA puts 3D-printed satellite antenna to the test

We can't print entire satellites yet, but the 3D printing of major components is moving forward with ESA unveiling a prototype 3D-printed radio antenna. Currently undergoing testing at ESA's Compact Antenna Test Facility in Noordwijk, the Netherlands, it's the space agency's first 3D-printed dual-reflector antenna incorporating a corrugated feed horn and two reflectors.Read More
