An international team of researchers has used the NASA/ESA/CSA James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet’s thermal emission: heat energy given off in the form of infrared light detected by Webb’s Mid-Infrared Instrument (MIRI). The result indicates that the planet’s dayside […]
The two spacecraft forming ESA’s Proba-3 mission for precise formation flying in orbit are now complete. All the instruments and sensors allowing them to manoeuvre to millimetre scale precision relative to one another have been integrated aboard, and the pair are fully wrapped in multi-layer insulation – ready to be tested in simulated space conditions.
