CHRIS satellite imager celebrates 7 years’ scientific success

10.11.2008
The scientific community is celebrating 7 years of high resolution hyperspectral satellite imagery from the highly successful CHRIS multi-spectral payload imager.

The instrument has been so successful that an advanced variant is under development, offering new functionality for Earth observation missions in a wide range of applications in resource monitoring and mapping, environmental science and security.

CHRIS (Compact High Resolution Imaging Spectrometer) was developed by SSTL's Optical Payload Group (formerly Sira Space Group), and placed into orbit in October 2001 on the PROBA mission developed by the European Space Agency (ESA). The sophisticated optical earth imaging instrument recently passed its 7th year in orbit as the highest resolution civil hyperspectral instrument in space.

Data from CHRIS has been highly successful in development of new Earth observation applications, and is supporting 94 international Principal Investigators (PIs), acquiring images from over 240 sites in 43 countries for diverse scientific research.

Dr. Mike Cutter, SSTL Optical Payloads Group explained the importance and value of such instrumentation, "Hyperspectral instruments have been widely used on aircraft for mineral prospecting and resource management and the CHRIS instruments enable this capability to be used on a national and continental scale, which is critical both for efficient management of natural resources and for providing the information to determine the effects of climate change and mitigation measures."

SSTL’s subsidiary DMCii schedules and processes images captured by CHRIS for ESA. The data from the mission then used in a wide range of applications including land cover assessment, resource management, deforestation and forest management, precision farming, aerosol monitoring and water quality assessment. The mission also supports International Charter: Space and Major Disasters campaigns by providing high resolution optical imagery of disaster affected areas.

The CHRIS hyperspectral images have been in high demand over the past 7 years, and the PROBA / CHRIS mission has pioneered and validated techniques for future scientific and commercial imaging spectrometer missions. Another reason for the scientific demand is that images can be acquired at 5 different view angles for each site, on a single over pass, allowing both spectral and directional signatures to be captured.

The new, more advanced CHRIS-2 instrument expands upon this unique capability by including the short wave infra-red band (SWIR), which allows further valuable applications to be addressed including mineralogy, prospecting, crop health and pollution monitoring.

Hyperspectral imagers split the available light from a scene into a large range of channels, providing detailed information about the imagery content. Whereas the CHRIS instrument provided up to 62 channels in the visible band, the CHRIS-2 instrument extends this capability to over 200 bands, including the short-wave infra-red bands (SWIR). Placing such an instrument on a spacecraft provides global reach and supports national and international routine imaging campaigns efficiently.

SSTL will provide the CHRIS-2 instrument on future Earth observation missions or as a stand-alone payload for integration with third party satellite platforms.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
