UK methane leak spotted using satellites

Researchers from the University of Leeds have detected methane leaking from a faulty pipe in Cheltenham, Gloucestershire, UK, using GHGSat satellite data – part of ESA’s Third Party Mission Programme . This marks the first time a UK methane emission has been identified from space and successfully mitigated. To source

Vega-C and Sentinel-1C launch highlights

Video: 00:03:40 The third Copernicus Sentinel-1  satellite, Sentinel-1C, has launched aboard a Vega-C  rocket, flight VV25, from Europe’s Spaceport in French Guiana. The rocket lifted off on 5 December 2024 at 22:20 CET (18:20 local time). Sentinel-1C extends the legacy of its predecessors, delivering high-resolution radar imagery to monitor Earth’s changing environment, supporting a diverse range of applications and advance scientific research. Additionally, Sentinel-1C introduces new capabilities for detecting […]

Proba-3 launch campaign replay

Video: 00:01:21 Proba-3 lifted off on its PSLV-XL rocket from Satish Dhawan Space Centre in Sriharikota, India, on Thursday, 5 December, at 11:34 CET (10:34 GMT, 16:04 local time). The mission was launched using this Indian launcher because it needed to be placed in a highly elliptical orbit extending more than 60 500 km from […]

Eclipse-making double satellite Proba-3 enters orbit

A pair of spacecraft were launched together today from India with the potential to change the nature of future space missions. ESA’s twin Proba-3 platforms will perform precise formation flying down to a single millimetre, as if they were one single giant spacecraft. To demonstrate their degree of control, the pair will produce artificial solar […]

Webb finds surprises in Spiderweb protocluster field

Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers have found new galaxies in the Spiderweb protocluster. Their characteristics reveal that new galaxies are forming in these large cosmic cities, with the finding that gravitational interactions in these dense regions are not as important as previously thought.

Creating artificial eclipses to study the Sun | Proba-3 explained

Video: 00:09:01 Proba-3  is such an ambitious mission that it needs more than one single spacecraft to succeed. In order for Proba-3’s Coronagraph spacecraft to observe the Sun’s faint surrounding atmosphere, its disk-bearing Occulter spacecraft must block out the fiery solar disk. This means Proba-3’s Occulter ends up facing the Sun continuously, making it a […]

Five space mysteries Proba-3 will help solve

ESA’s Proba-3 will be the first mission to create an artificial total solar eclipse by flying a pair of satellites 150 metres apart. For six hours at a time, it will be able to see the Sun’s faint atmosphere, the corona, in the hard-to-observe region between the Sun’s edge and 1.4 million kilometres from its […]
