The voice counted backwards in French from ten to one, then announced, “Décollage” – lift-off. The 15-year-long collaboration between NASA, ESA and the Canadian Space Agency had just entered its most critical phase: the launch itself. What happened next would determine whether the James Webb Space Telescope made it into space or not. View the full article

Video: 00:07:33 2022 was a year of many ‘firsts’ for space in Europe, seeing the first European female ISS commander, the launch of the first Vega-C rocket, Solar Orbiter’s first close encounter with our home star, the launch of the first Artemis mission working to bring humans back to the Moon, and first images from the James Webb Space Telescope. Let’s take a look at the highlights and accomplishments of the European Space Agency during 2022. View the full article

At this time of the year, the mention of Lapland conjures up visions of Santa getting his gift-laden sleigh and nine reindeer ready to take to the skies for the most important deliveries of all. However, the skies of Lapland have witnessed something rather different recently – a big white balloon, which may not provide the immediate gratification of a much-wanted Christmas present, but nonetheless plays a role in helping to safeguard our children’s future.

Making satellite navigation sufficiently accurate by improving its integrity for aircraft to rely on, the European Geostationary Navigation Overlay System, EGNOS, is today employed by hundreds of airports across our continent, guiding airliners down through all weathers to the point where pilots gain sight of runways to initiate landing. Now an upgraded version of the system, EGNOS v3, has passed its Critical Design Review – putting it on track to enter service by the second part of the decade. View the full article

Researchers have found evidence for the existence of a new type of planet they have called a “water world,” where water makes up a large fraction of the entire planet. These worlds, discovered in a planetary system 218 light-years away, are unlike any planets in our Solar System. View the full article

The Meteosat Third Generation Imager satellite, set to revolutionise short-term weather forecasting in Europe, lifted off on an Ariane 5 rocket at 21:30 CET (17:30 local time in Kourou) on 13 December from Europe’s Spaceport in French Guiana. The satellite separated from the rocket 34 minutes later and then Malindi ground station in Kenya received the signal from MTG-I1, indicating the satellite is in good health. View the full article

Video: 00:03:13 Watch the replay the MTG-I1 launch coverage. The video includes streaming of the event at ESA’s ESTEC establishment in the Netherlands and footage of liftoff from Europe’s Spaceport in French Guiana. The first Meteosat Third Generation Imager (MTG-I1) satellite lifted off on an Ariane 5 rocket from Europe’s Spaceport in French Guiana on 13 December at 21:30 CET. From geostationary orbit, 36,000 km above the equator, this all-new weather satellite will provide state-of-the art observations of Earth’s atmosphere and realtime monitoring of lightning events, taking weather forecasting to the next level. The satellite carries two completely new instruments: Europe’s first Lightning Imager and a Flexible Combined Imager. MTG-I1 is the first of six satellites that form the full MTG system, which will provide critical data for weather forecasting over the next 20 years. In full operations, the mission will comprise two MTG-I satellites and one MTG Sounding (MTG-S) satellites working in tandem. The MTG mission is a cooperation between Eumetsat and ESA. ESA is responsible developing and procuring the six MTG satellites. Eumetsat defines the system requirements, develops the ground systems, procures the launch services, operates the satellites, and makes the data available to users. View the full article

Video: 00:01:11 The uncrewed Artemis I test flight saw Orion travel around the Moon and farther than any spacecraft designed to carry humans and return them to Earth. Artemis is the international lunar exploration programme that is taking humankind to the Moon. This first mission provided a first test of both NASA’s Space Launch System (SLS) and the Orion moonship that was propelled by the European Service Module’s 33 engines beyond the Moon and into deep space. Future European Service Modules will provide electricity, propulsion and cabin thermal control for astronauts on lunar missions as well as breathable atmosphere and drinking water. Launched by the first SLS on 16 November at 06:47 GMT/07:47 CET (01:47 local time) from NASA’s Kennedy Space Center, Florida, Orion flew a 25-day mission that saw it fly by the Moon twice. Passing as close as 130 km from the lunar surface, the spacecraft used the Moon’s gravity to sling it into lunar orbit and then later return it on course to Earth. The first lunar flyby occurred on 21 November at 12:44 GMT/13:44 CET, with the ESM firing its main engine to send Orion behind and around the Moon. Ten days after liftoff, Orion entered the Moon’s orbit at 12:44 GMT/13:44 CET on 25 November when the ESM fired its main engine. NASA’s Orion spacecraft splashed down in the Pacific Ocean at 17:40 GMT/18:40 CET on 11 December, after travelling around the Moon and farther than any spacecraft designed to carry humans and return them to Earth. Just 40 minutes before splashdown, and having delivered Orion safely back to Earth, ESA’s European Service Module (ESM) with its Crew Module Adapter detached from the capsule. As planned, the ESM burned up harmlessly in the atmosphere as the Orion Crew Module guided itself through re-entry, orienting the capsule with its own thrusters, releasing its three parachutes and gracefully splashing down off the coast of San Diego, USA.

With liftoff set for today at 21:30 CET, the Ariane 5 rocket carrying the first Meteosat Third Generation Imager, MTG-I1, satellite is poised patiently on the launch pad at Europe’s Spaceport in French Guiana while the final checks are being carried out. Once in geostationary orbit, 36,000 km above the equator, this new satellite is set to herald a new era for meteorology. View the full article
