European Service Module 3

Video: 00:04:15

The Artemis programme is bringing humans back to the Moon. It depends heavily on NASA's Orion spacecraft that consists of a crew module and the European Service Module, which will provide propulsion, life support, environmental control and electrical power. Main contractor Airbus has just been green-lighted by ESA to develop a third European Service Module.

This A&B Roll highlights the Artemis programme and development of the European Service Module, using cleanroom footage and animation, with interviews in English and German.

Third European Service Module for mission to land astronauts on the Moon

Orion and European Service Module orbiting the Moon

It’s official: when astronauts land on the Moon in 2024 they will get there with help from the European Service Module. The European Space Agency signed a contract with Airbus to build the third European Service Module for NASA’s Orion spacecraft that will ferry the next astronauts to land on the Moon.

Galactic crash may have triggered Solar System formation

The formation of the Sun, the Solar System and the subsequent emergence of life on Earth may be a consequence of a collision between our galaxy, the Milky Way, and a smaller galaxy called Sagittarius, discovered in the 1990s to be orbiting our galactic home.

One billion stars and counting – the sky according to Gaia’s second data release

Video: 00:01:20

Animation of data from ESA’s Gaia second release, which was made public on 25 April 2018.

Launched in 2013, the Gaia satellite has been scanning the sky to measure the positions, distances and motions of more than one billion stars in our galaxy, the Milky Way. The goal of the mission is to create the most detailed galactic map ever made, in order to investigate the Milky Way’s past and future history like never before.

This animation shows the satellite as it scans great circles around the sky. Eventually, the sky is unfolded to reveal the view of the Milky Way and neighbouring galaxies, based on measurements of nearly 1.7 billion stars from the second Gaia data release. The map shows the total brightness and colour of stars observed by Gaia in each portion of the sky between July 2014 and May 2016. Brighter regions indicate denser concentrations of especially bright stars, while darker regions correspond to patches of the sky where fewer bright stars are observed. In the middle of the image, the Galactic centre appears vivid and teeming with stars.

Sprinkled across the image are also many globular and open clusters – groupings of stars held together by their mutual gravity, as well as entire galaxies beyond our own. The two bright objects in the lower right of the image are the Large and Small Magellanic Clouds, two dwarf galaxies orbiting the Milky Way.

The animation ends with a pan over the Galactic plane, the bright horizontal structure that hosts most of the stars in our home Galaxy. Darker regions across the Galactic plane correspond to foreground clouds of interstellar gas and dust, which absorb the light of stars located further away, behind the clouds. Many of these conceal stellar nurseries where new generations of stars are being born.

The two Gaia data releases, published in 2016 and 2018, have revolutionised the study of the Milky Way, enabling thousands of studies about the structure and motions of our galaxy. More releases are planned in coming years.

The all-sky image from the second Gaia data release, published in 2018, is available here.
