MERLIN - Die deutsch-französische Klimamission
Die deutsch-französische Klimamission (MERLIN) ist eine Kleinsatellitenmission zur Beobachtung des Treibhausgases Methan in der Erdatmosphäre. Der Missionsname MERLIN steht für „Methane Remote Sensing LIDAR Mission“. Es handelt sich um eine Kleinsatellitenmission mit einem Methan-LIDAR (Light Detecting and Ranging)-Messinstrument. Der Satellit soll 2016 in einen niedrigen polaren Orbit gestartet werden und mindestens 3 Jahre in Betrieb sein. Mit diesem Schritt haben sich die beiden größten Raumfahrtnationen Europas entschieden, durch ihre Raumfahrtagenturen CNES und DLR einen sichtbaren Beitrag zur Bewältigung des Klimawandels zu leisten.

EnMAP
Das Hauptziel des der Hyperspektral-Satellitenmission EnMAP ist es, einen weiten Bereich des Ökosystems auf der Landoberfläche der Erde zu untersuchen. Hyperspektralinstrumente registrieren die von der Erde reflektierte Sonnenstrahlung vom sichtbaren Licht bis zum kurzwelligen Infrarot.

TanDEM-X
The TanDEM-X mission is based on two nearly identical earth observation satellites, TerraSAR-X and TanDEM-X. Both are equipped with a powerful modern radar system. With its two antennas, the satellite pair will be the first ever capable of generating a three-dimensional elevation model of the entire surface of the earth.

TerraSAR-X
TerraSAR-X is a new German radar satellite designed for Earth observation. The project was the first to be implemented by a public-private partnership in which both parties contribute towards financing the system.

RapidEye
The RapidEye satellite project marks the transition to a new level of quality in earth exploration data services. The daily availability of extremely sharp high-resolution images from space will open up a commercial market of its own. For the first time, this has induced a private German company to invest large sums in a space project.

GRACE - Gravity Recovery and Climate Experiment
The US-German mini-satellite mission GRACE will help scientists develop a new model of the Earth’s gravitational field with unprecedented accuracy. The following questions will be addressed: Are the polar ice-caps melting? Are sea levels rising? Are we likely to see major flood events? Why do warm ocean currents like the gulf stream reach so high up into the Earth’s northern hemisphere, and what role does the influence of gravitation play in that context?

CHAMP - A geoscience mission to "Planet Earth"
Conceived at the Potsdam GeoResearch Centre, CHAMP is a research satellite which, operating from a near-Earth orbit, made important contributions towards the exploration of the Earth’s magnetic and gravitational field as well as for atmospheric physics. It provided reference data of hitherto unattained accuracy for geodesy, new insights in geophysics and oceanography, and contributions to climate research.

ENVISAT - Der europäische Umweltsatellit
Am 1. März 2002 brachte eine Ariane 5 Europas größten Satelliten ENVISAT (Enviromental Satellite) vom europäischen Weltraumbahnhof Kourou in Französisch Guayana auf seine Umlaufbahn in 800 Kilometern Höhe. Seither umkreist er die Erde 14 Mal am Tag und sammelt Daten über den Zustand der Ozeane und der Landökosysteme, die Bewegung von Gletschern und Erdplatten sowie die Belastung der Luft.

SCIAMACHY
Die SCIAMACHY-Mission wurde ins Leben gerufen, um mehr über das Zusammenspiel physikalischer und chemischer Vorgänge in der Erdatmosphäre zu erfahren. Dabei spielt der anthropogene Beitrag an globalen Veränderungen im atmosphärischen System eine besondere Bedeutung.

BIRD - The first satellite for spotting forest fires
From the ground, forest fires are often discovered very late. However, they can be spotted much earlier from the air or even from space. DLR is testing the technologies of such an early warning system with BIRD (bi-spectral infra-red detection), a small satellite that was successfully launched from India on 22 October 2001.
