A "Swarm" of satellites for a unique look inside the Earth

04.06.2004


ESA PR 30-2004. ESA’s Earth Observation Programme Board has just decided which of the six Earth Explorer candidate missions, presented earlier in April at the User Consultation Meeting, will be developed and launched. Swarm, an Earth Explorer Opportunity Mission, is a constellation of satellites which will study the Earth’s magnetic field.

A further selection between the Earth Explorer Core Missions EarthCARE (Earth Clouds Aerosols and Radiation Explorer) and SPECTRA (Surface Processes and Ecosystem Changes Through Response Analysis) has been deferred to November 2004 allowing clarifications to be made for both missions. It was recommended that the EGPM (European contribution to Global Precipitation Measurement) mission should be furthered within the ESA Earth Watch framework.

Based upon the recommendations made by the Earth Science Advisory Committee and the ESA Director of Earth Observation, the choice of Swarm for full implementation was unanimously agreed upon as a result of its scientific excellence. ESA has successfully moved to the next round of missions that explore our environment and the Earth as a system. Together with the decision expected in November for an additional Core Explorer, ESA is at a point where the next generation of scientific missions can be initiated. In this context the Agency is planning a Call for Mission Proposals in September 2004.


The objective of the Swarm mission is to provide the best ever survey of the geomagnetic field and its temporal evolution, in order to gain new insights into the Earth system by improving our understanding of the Earth’s interior and climate. The mission is scheduled for launch in 2009. After release from a single launcher, a side-by-side flying lower pair of satellites at an initial altitude of 450 km and a single higher satellite at 530 km will form the Swarm constellation.

High-precision and high-resolution measurements of the strength, direction and variation of the magnetic field, complemented by precise navigation, accelerometer and electric field measurements, will provide the necessary observations that are required to separate and model various sources of the geomagnetic field. This results in a unique “view” inside the Earth from space to study the composition and processes in the interior. It also allows the analysis of the Sun’s influence within the Earth system. In addition, practical applications in many different areas, such as space weather, radiation hazards, navigation and resource exploration, benefit from the Swarm concept.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
