Stop aging in space

Wrinkles, muscle pain, high blood pressure and a clumsy brain are all natural consequences of getting old. As our cells rust over time, a key to fighting chronic disease may be in tiny, smartly designed particles that have ...

Image: Ries crater, Germany

The Copernicus Sentinel-2 mission takes us over an area in southern Germany, where approximately 15 million years ago an asteroid crashed through Earth's atmosphere. The high-speed impact formed what is now known as the Ries ...

FRIPON camera atop ESTEC

Asteroid researcher Kristiane Schmidt and ESA data technician Andrea Toni inspect a camera fixed to the five-storey-high rooftop of ESA's technical heart in the Netherlands, keeping a constant watch for fireballs – very ...

Hera's CubeSat to perform first radar probe of an asteroid

Small enough to be an aircraft carry-on, the Juventas spacecraft nevertheless has big mission goals. Once in orbit around its target body, Juventas will unfurl an antenna larger than itself, to perform the very first subsurface ...

Image: Smart particles

Down to the microscopic level, nanoparticles show promising properties. A team of experts in Italy has spent years tailoring tiny inorganic materials and analysing their behaviour. Some have magnetic properties, others are ...

Gaia's first asteroid discoveries

While scanning the sky to chart a billion stars in our Milky Way galaxy, ESA's Gaia satellite is also sensitive to celestial bodies closer to home, and regularly observes asteroids in our solar system.

The day the asteroid might hit

For the first time, ESA will cover a major international asteroid impact exercise live via social media, highlighting the the actions that might be taken by scientists, space agencies and civil protection organisations.

Image: Queensland floods

The Copernicus Sentinel-2 mission takes us over Australia's northeast state of Queensland, where a large amount of sediment is visible gushing into the Coral Sea, close to the Great Barrier Reef lagoon.

Image: Testing satellite marker designs

Akin to landing lights for aircraft, ESA is developing infrared and phosphorescent markers for satellites, to help future space servicing vehicles rendezvous and dock with their targets.

Image: New comet viewer

From a distance of five million kilometres to within 20 metres, ESA's Rosetta spacecraft captured images of Comet 67P/Churyumov-Gerasimenko from all angles.
