3-D printing a lunar base

November 7, 2014 9:29 am | by European Space Agency | News | Comments

Could astronauts one day be printing rather than building a base on the Moon? In 2013 ESA, working with industrial partners, proved that 3-D printing using lunar material was feasible in principle. Since then, work continues to investigate the technique.

Dark universe mission blueprint complete

The European Space Agency's Euclid mission to explore the hidden side of the universe—dark energy and dark matter—reached an important milestone that will see it head towards full construction.

ESA tests self-steering rover in 'Mars' desert

June 19, 2012 7:44 am | News | Comments

The European Space Agency (ESA) assembled a top engineering team then challenged them to devise a way for rovers to navigate on alien planets. Six months later, a fully autonomous vehicle was charting its own course through Chile's Mars-like Atacama Desert.

Imagery reveals Martian summits where buried ice lies

December 2, 2011 11:14 am | News | Comments

New images from ESA’s Mars Express show the Phlegra Montes mountain range in greater detail. The range is in a region where radar probing has indicated large volumes of water ice should be hiding below. This could be a source of water for future astronauts.

ESA finds that Venus has an ozone layer too

October 10, 2011 4:40 am | News | Comments

The European Space Agency’s Venus Express spacecraft has discovered an ozone layer high in the atmosphere of Venus. Ozone has only previously been detected in the atmospheres of Earth and Mars. On Earth, it is both generated by and protects life from the sun’s harmful rays, but on Mars and Venus, the effect is non-biological.

Dark and bright: ESA chooses next two science missions

October 5, 2011 5:42 am | News | Comments

The powerful influence of the Sun and the nature of mysterious dark energy motivate ESA’s next two science missions. Solar Orbiter will venture closer to the Sun than any previous mission, and Euclid will be a space telescope designed to map out the large-scale structure of the cosmos.

Massive trenches accentuate Mars’ methane mystery

May 6, 2011 10:34 am | News | Comments

The great “canyon” formed by Nili Fossae on Mars is a lot like the Dead Sea, a depressed region between two faults. But instead of a salt sea, this great rift on Mars, recently imaged in spectacular detail by the European Space Agency, is thought to be the source of elevated methane levels that have been detected by telescopes on Earth.

First galaxies were born much earlier than expected

April 12, 2011 9:24 am | News | Comments

Using a cosmic gravitational lens, astronomers using the Hubble Space Telescope have discovered a distant galaxy whose stars were born unexpectedly early in cosmic history. So early, in fact, that its stars were born just 200 million years after the Big Bang. The discovery may help explain, in a roundabout way, the deficit of radiation that has caused the Universe to be transparent to ultraviolet light.
