The mirror array seen in the image reflects simulated sunlight into the chamber, at the same time as the walls are pumped full of –190°C liquid nitrogen, together recreating the extreme thermal conditions prevailing in orbit. Portuguese-bornEdgar Martinscollaborated closely with ESA to produce a...
Electrical Power System (EPS), comprising one solar array wing providing power to the spacecraft and payload. Attitude and Orbit Control System (AOCS) composed of a coarse sun sensor, magnetometers, coarse rate sensors, star trackers, a GNSS receiver and control actuators including thrusters, magn...

is published in Nature 26 September 2013. The study is based on data from a number of space-based high-energy observatories and ground-based radio telescopes: ESA’s Integral and XMM-Newton and NASA’s Swift and Chandra space telescopes, and CSIRO's Australia Telescope Compact Array and ...
Bank Telescope; the NASA/ESA Hubble Space Telescope; the William Herschel Telescope at La Palma, Spain; the IRAM/Plateau de Bure Interferometer (PdBI); the Max-Planck Millimetre Bolometer 2 (MAMBO2) at the IRAM 30m telescope; the Combined Array for Research in Millimeter-wave Astronomy (CARMA...
Solar Orbiter array deployment Access the video Solar Orbiter’s solar arrays presented another engineering challenge. The temperature the cells are exposed to varies with the spacecraft’s distance from the Sun. At its closest (42 million km from the Sun) the temperature far exceeds 300 °...
MetOp, due to lift-off in just a week's time, will be the second largest European Earth Observation satellite ever launched. Developed by ESA and EUMETSAT as part of a joint undertaking, this new satellite is dedicated to operational meteorology and carries an impressive array of instrumen...
Herschel carries three science instruments: HIFI (Heterodyne Instrument for the Far Infrared), a high-resolution spectrometer; PACS (Photoconductor Array Camera and Spectrometer); SPIRE (Spectral and Photometric Imaging REceiver). PACS and SPIRE are both cameras and imaging spectrometers that together cov...
120 °C), so they were more suitable for hot environments. Moreover, they were able to exploit a wider range of solar radiation. The solar cells were separated by aluminium strips that helped to reject heat. All together, these aluminium strips covered half of the overall solar array ...
Dante Galli, ESA’s Space Rider Programme Manager, said: “Space Rider is our very own uncrewed laboratory in space.” Using flight control concepts and aerodynamics demonstrated by ESA’sIntermediate eXperimental Vehicle(IXV) programme, Space Rider will transport payloads for an array of application...
