    Another pair of eyes provides a sobering perspective on the fires ravaging Australia. ESA astronaut Luca Parmitano took images such as this one on 12 January from his vantage point of the International Space Station.

    From satellite imagery tracing smoke and pollution, to images from the ground depicting apocalyptic red skies, there is no denying the fires’ devastating effect.

    Starting in New South Wales and extending into Victoria, the ferocious bushfires have been raging since September and are fuelled by record-breaking temperatures. In the midst of a climate crisis, 2019 was the hottest year on record in Australia and with drought and wind, the fires have raged beyond seasonal expectations.

    Winds have blown smoke over New Zealand and crossed the South Pacific Ocean, even reaching Chile and Argentina.

    A staggering 10 million hectares of land have been burned, at least 24 people have been killed and it has been reported that almost half a billion animals have perished.

    Damage to wildlife notwithstanding, the fires have had a serious effect on air quality. Earth observation satellites like Copernicus Sentinel-5 Precursor has traced increased concentrations of carbon monoxide in the past months along Australia’s southeast coast.

    This image was taken as the Station flew above Fraser Range, in Western Australia, near the Dundas Nature Reserve.

    Luca posted images of the fire to social media and said: “Talking to my crew mates, we realised that none of us had ever seen fires at such terrifying scale”.

    Astronaut photographs of Earth from space complement satellite imagery, allowing experts and the general public more insight on global events.

    Like Luca, the world continues to monitor the fires. If there is a silver lining around the smoke, it is the increased awareness of and calls for urgent action on climate change that is continuing to sweep the globe.

    The first flight of the Artemis programme, which will see humans return to the Moon, is scheduled to begin soon. The lunar spacecraft consists of NASA's Orion crew module and the European Service Module, or ESM. Developed by ESA  and building on technology from its Automated Transfer Vehicle (ATV), the ESM will provide propulsion, life support, environmental control and electrical power to Orion. The Artemis 1 spacecraft modules are undergoing thermal vacuum and electromagnetic interference tests in the world's largest space simulation vacuum chamber at the Glenn Research Centre's Plum Brook Station in Sandusky, Ohio, USA. 

    This A&B Roll highlights preparations and testing of Orion at Plum Brook Station with interviews in English and French.

    What started as an experiment to understand how to get the most out of oil reservoirs has spawned more investigations that are creating medicine with longer shelf life and is helping scientists understand how liquids mix on a molecular level.
