  • GOCE: Geoid

    GOCE: Geoid

    Launched on 17 March 2009, ESA’s Gravity field and steady-state Ocean Circulation Explorer (GOCE) is bringing about a whole new level of understanding of one of Earth’s most fundamental forces of nature: the gravity field. Dubbed the ‘Formula 1’ of satellites, GOCE is mapping Earth’s gravity field in unprecedented detail.

    This has given rise to a unique model of the ‘geoid’, which is the surface of an hypothetical global ocean in the absence of tides and currents, shaped only by gravity. It is a crucial reference for measuring ocean circulation and sea-level change, which are affected by climate change.

    The colours in the image represent deviations in height ( -100 m to + 100 m) from an ideal geoid. The blue colours represent low values and the reds/yellows represent high values.

  • Using LEGO® to simulate ESA’s touchdown on a comet

    Using LEGO® to simulate ESA’s touchdown on a comet

    Comets are primeval leftovers from the origins of the Solar System. To fully understand these ancient objects and perhaps the origins of life on Earth, ESA’s Rosetta mission will rendezvous with comet Churyumov-Gerasimenko in 2014. In November of that year, Rosetta’s Philae lander will touchdown on the comet and thoroughly investigate its composition.

    ESA Space Scientist Detlef Koschny explains why he originally built Rosetta in LEGO®

    Space missions are complicated pieces of orbital choreography. When planning a mission, spacecraft engineers must calculate how to point the solar panels towards the Sun, the main antenna towards Earth and the instruments towards the target. ESA Space Scientist Detlef Koschny build a LEGO model of Rosetta mission in order to visualise these precise orientations.

As part of ESA’s Rosetta space mission, Philae will land on comet Churyumov-Gerasimenko in November 2014 to study its composition.

In three separate robotic missions (the first in 2016), both agencies will study the possibility of past life on the Red Planet, as well as test communications relays and other geochemical and biological mysteries. The third mission, in the 2020’s, will return to Earth a sample taken from the Martian surface.

    How do you feel after the first few months in orbit?

    Frank De Winne is answering a few questions on the ISS submitted by the pupils of Class 7M from the Christian Morgenstern School in Hersching (Germany):

    Question:
    – Jerome (13): How do you feel in orbit after 2 months?
    – Karina (13): How much time do you spend working outside the ISS?
    – Tamara: Do you have any real free time in the ISS, and how can you spend this time? How often do you contact your family?
    – Antoine (13): Have you ever felt scared in orbit? Has there ever been a moment that you wished to be back on Earth?
    – Regina (14): Has anything strange happened on the ISS that none of your colleagues have been able to explain?
    – Flavu: Which kind of education and qualification do you need for this kind of work?

With Ariane, ESA could develop its own programmes in many different domains: telecommunications, Earth observation, science and exploration. Europe was the pioneer in the civil launch space market, with the creation of Arianespace, the world-leading space transportation company.
