Japan’s ALOS in orbit: ESA will deliver its data to European researchers

24.01.2006


ALOS, Japan’s latest Earth Observation satellite, was successfully launched at 02:33 CET (10:33 Japan time) on 24 January. Environmental data and imagery from ALOS will be provided to European and African users through a cooperative agreement between ESA and the Japan Aerospace Exploration Agency (JAXA).



The Advanced Land Observing Satellite (ALOS) is a four-tonne satellite dedicated to land-based Earth Observation. It was lifted-off from the Tanegashima Space Centre on an H-IIA launch vehicle, which will deliver ALOS into a 700-km polar orbit.

ESA is supporting ALOS as a ’Third Party Mission’, which means the Agency will utilise its multi-mission ground systems of existing national and industrial facilities and expertise to acquire, process and distribute data from the satellite. Based on a Memorandum of Understanding with JAXA, approved at ESA Council in December and now ready for signature, ESA will host the ALOS European Data Node (ADEN), delivering near-real time and offline data to scientific and operational users across Europe as well as Africa.


ALOS has multiple objectives: to support improved cartography, especially within the Asia-Pacific region, to gather environmental observations in support of sustainable development efforts, to survey natural resources, to develop technologies for further Earth Observation missions and to monitor disasters on a worldwide basis – JAXA having signed the International Charter on Major Disasters in February 2005.

The satellite carries a payload of three instruments: the Phased Array type L-band Synthetic Aperture Radar (PALSAR), a microwave radar instrument that can acquire observations during both day and night and through any weather conditions; the Panchromatic Remote-sensing Instrument of Stereo Mapping (PRISM) which can observe selected areas in three dimensions, down to a high 2.5-metre spatial resolution; and the Advanced Visible and Near Infrared Radiometer type-2 (AVNIR-2), designed to chart land cover and vegetation in visible and near infrared spectral bands.

Observing in L-band wavelength, PALSAR will complement ESA radar instruments currently flying on ERS-2 and Envisat operating in C-band wave, and the European national missions TerraSAR-X and Cosmo SkyMed, operating in the even shorter X-band.

Regarding optical sensors, the very high resolution together with the stereo mapping and DEM generation capability of PRISM will be particularly valuable. AVNIR-2 will provide in addition high resolution multispectral imagery for use in local to regional studies, complementing the optical data from medium resolution instruments currently available from ESA.

Following launch, a nine month commissioning phase will begin, with products set to be available to users from November 2006. ALOS data will be made available at conditions similar to those of ERS and Envisat missions, namely for scientific ’Category-1’ use as well as commercial applications.

An ESA Announcement of Opportunity for scientific use of ALOS data has already received almost 150 proposals which are currently undergoing evaluation by scientific experts from ESA Member States and JAXA.

Operational and commercial users will be able to receive ALOS data via commercial distribution schemes. ALOS data will also be available for Global Monitoring for Environment and Security (GMES), the joint initiative by ESA and the European Union to develop an independent environmental monitoring capability for Europe.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
