Video: 00:14:09 The Copernicus Sentinel-2C satellite lifted off on 5 September at 03:50 CEST (4 September 22:50 local time) aboard the last Vega rocket, flight VV24, from Europe’s Spaceport in French Guiana. Sentinel-2C will continue the legacy of delivering high-resolution data that are essential to Copernicus – the Earth observation component of the EU Space Programme. Developed, built and operated by ESA, the Copernicus Sentinel-2 mission provides high-resolution optical imagery for a wide range of applications including land, water and atmospheric monitoring. Sentinel-2C was the last liftoff for the Vega rocket – after 12 years of service this was the final flight, the original Vega is being retired to make way for an upgraded Vega-C.

The third Copernicus Sentinel-2 satellite launched today aboard the final Vega rocket from Europe’s Spaceport in French Guiana. Sentinel-2C will continue providing high-resolution data that is essential to Copernicus – Europe’s world leading Earth observation programme. Sentinel-2C launched into orbit on 5 September at 03:50 CEST (4 September 22:50 local time) and separated from the Vega rocket at approximately 04:48 CEST. View the full article

According to recent research, Europe’s net greenhouse gas emissions have decreased by around 25% since the 1990s. While this is good news, the study also revealed a weakening in the capacity of land and vegetation to absorb and store atmospheric carbon. View the full article

ESA mission controllers have completed the final phase of their simulation training for the critical launch and early orbit phase, confirming that everything is ready for the launch of Sentinel-2C. View the full article

The Copernicus Sentinel-2C satellite is ready for liftoff! Tune in to ESA WebTV on 4 September from 03:30 CEST to watch the satellite soar into space on the last Vega rocket to be launched from Europe’s Spaceport in Kourou, French Guiana. Sentinel-2C is scheduled to liftoff at 03:50 CEST. View the full article

Teams from across ESA and industry have worked continuously over the past four months to overcome a glitch that prevented BepiColombo’s thrusters from operating at full power. The ESA/JAXA mission is still on track, with a new trajectory that will take it just 165 km from Mercury’s surface on Wednesday. Taking BepiColombo closer to Mercury than it’s ever been before, this flyby will reduce the spacecraft’s speed and change its direction. It also gives us the opportunity to snap images and fine-tune science instrument operations at Mercury before the main mission begins. Closest approach is scheduled for 23:48 CEST (21:48 UTC) on 4 September. View the full article

Video: 00:02:32 Sentinel-2C is ready for launch! The new satellite will soon join its Copernicus Sentinel-2 family in orbit – where it will continue to provide detailed views of Earth’s land and coastal waters. The mission is based on a constellation of two identical satellites: Sentinel-2A and Sentinel-2B. The constellation was originally designed to monitor land surfaces – but its scope has since expanded. It now covers a wide range of applications including deforestation, water quality, monitoring natural disasters, methane emissions and much more. Sentinel-2C, once in orbit, will replace the Sentinel-2A unit – prolonging the life of the Sentinel-2 mission – ensuring a continuous supply of data for Copernicus, the Earth observation component of the EU Space Programme. Tune in to ESA WebTV on 4 September from 03:30 CEST to watch the satellite soar into space on the last Vega rocket to be launched from Europe’s Spaceport in Kourou, French Guiana.

Video: 00:52:00 The Copernicus Sentinel-2C satellite is set for liftoff on 4 September on the last Vega rocket from Europe’s Spaceport in Kourou, French Guiana. This recording is of a media briefing held on 29 August 2024 to offer journalists the possibility to learn more about the Sentinel-2 mission and the last flight of Vega, Europe’s nimble rocket specialising in launching small scientific and Earth observation spacecraft such as to sun-synchronous polar orbits, following the Sun. The Sentinel-2 mission is based on a constellation of two identical satellites, Sentinel-2A and Sentinel-2B, flying in the same orbit but 180° apart to optimise coverage and revisit time. Once in orbit, Sentinel-2C will replace the Sentinel-2A unit – prolonging the life of the Sentinel-2 mission – ensuring a continuous supply of data for Copernicus, the Earth observation component of the EU Space Programme. Data collected from Sentinel-2 are used for a wide range of applications, including precision farming, water quality monitoring, natural disaster management and methane emission detection. Participants at the media briefing were Simonetta Cheli, Director of Earth Observation Programmes, ESA Toni Tolker-Nielsen, Director of Space Transportation, ESA Stéphane Israël, CEO, Arianespace Mauro Facchini, Head of Unit for Earth Observation, European Commission View the full article

Video: 00:01:23 On 19–20 August 2024, Juice successfully completed a world-first lunar-Earth flyby, with flight controllers guiding the spacecraft first past the Moon, then past Earth. The gravity of the two changed Juice’s speed and direction, sending it on a shortcut to Jupiter via Venus. The closest approach to the Moon was at 23:15 CEST on 19 August, deflecting Juice towards a closest approach to Earth just over 24 hours later at 23:56 CEST on 20 August. In the hours before and after both close approaches, Juice’s two monitoring cameras captured photos, giving us a unique ‘Juice eye view’ of our home planet. Juice’s two monitoring cameras provide black-and-white snapshots in 1024 x 1024 pixel resolution (they can be processed in colour). Their main purpose is to monitor the spacecraft’s various booms and antennas, especially during the challenging period after launch. The photos they captured of the Moon and Earth during the lunar-Earth flyby are a bonus. The piece of music that accompanies the images is called 11,2 km/s. It was composed by Gautier Archer back in 2015, and selected as the official theme music for ESA’s Estrack ground station network to mark its 40th anniversary (more information). The music is available under a CC BY-NC-SA licence. Juice rerouted to Venus in world’s first lunar-Earth flyby Juice’s lunar-Earth flyby: all you need to know Processing notes: The Juice monitoring cameras provide 1024 x 1024 pixel images. Upscaling software was used to convert the images into 2160 x 2160 pixel images, which match the 3480 x 2160 pixel resolution of the 4K movie format. Access the related broadcast quality footage.

On 8 September 2024, the first of four Cluster satellites will return home and burn up in the Earth’s atmosphere in an uncontrolled ‘targeted reentry’ over a remote area of the South Pacific Ocean. In the nearly 70 years of spaceflight about 10 000 intact satellites and rocket bodies have reentered the atmosphere. Yet we still lack a clear view on what actually happens during a reentry. An airborne observation experiment will now attempt to witness the ‘Salsa’ (Cluster 2) reentry. Scientists onboard a small plane will try to collect rare data on how and when a satellite breaks up, which can be used to make satellite reentries safer and more sustainable in the future.

ESA’s Solar Orbiter spacecraft has provided crucial data to answer the decades-long question of where the energy comes from to heat and accelerate the solar wind. Working in tandem with NASA’s Parker Solar Probe, Solar Orbiter reveals that the energy needed to help power this outflow is coming from large fluctuations in the Sun’s magnetic field.

On 8 September 2024, the first of four satellites that make up ESA’s Cluster mission will reenter Earth’s atmosphere over the South Pacific Ocean Uninhabited Area. This marks the end of the historic mission, over 24 years after it was sent into space to measure Earth’s magnetic environment. Though the remaining three satellites will also stop making scientific observations, discoveries using existing mission data are expected for years to come. This ‘targeted reentry’ is the first of its kind. ESA’s efforts to ensure a clean end to the Cluster mission go beyond international standards, making the agency a world-leader in sustainable space exploration. View the full article

Launched in May, ESA’s EarthCARE satellite has been making waves, with the first images from three of its scientific instruments already delivered. Now, the spotlight is firmly on the atmospheric lidar, the most advanced of the satellite’s four instruments. This cutting-edge sensor has captured detailed 20 km-high vertical profiles of atmospheric aerosols – tiny particles and droplets from natural sources like wildfires, dust, and sea spray, and from human activities like industrial emissions or burning of wood – and clouds across various regions of the globe.
