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

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.

NASA astronaut Don Pettit during crew qualification exams at the Gagarin Cosmonaut Training Center.Credits: GCTC/Roscosmos NASA astronaut Don Pettit is available for limited interview opportunities beginning at 10 a.m. EDT, Friday, Aug. 16, to discuss his upcoming mission to the International Space Station in September.
The virtual interviews will stream live on NASA+, NASA Television, the NASA app, and the agency’s website. Learn how to stream NASA+ through a variety of platforms including social media.
Interested media must submit a request no later than 12 p.m., Thursday, Aug. 15, to the newsroom at NASA’s Johnson Space Center in Houston at 281-483-5111 or jsccommu@mail.nasa.gov.
Pettit will launch on the Roscosmos Soyuz MS-26 spacecraft, accompanied by Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner. The trio will spend approximately six months aboard the orbital laboratory before returning to Earth in the spring of 2025.
During his time in orbit, Pettit will conduct scientific investigations and technology demonstrations to help prepare the crew for future space missions and provide benefits to people on Earth. Pettit will participate in several of the hundreds of experiments happening during his mission, including studying how spaceflight affects blood clotting, continuing tests of technology to produce human stem cells in space, and contributing his unique photography skills to the long-running Crew Earth Observations study of how Earth is changing over time.
NASA selected Pettit as an astronaut in 1996. A veteran of three spaceflights, he has contributed to integral advancements in technology and demonstrations for human space exploration. He served as a science officer for Expedition 6 in 2003, operated the robotic arm for STS-126 space shuttle Endeavour in 2008, and served as a flight engineer for Expedition 30/31 in 2012. Pettit has logged 370 days in space and conducted two spacewalks totaling 13 hours and 17 minutes.
A native from Silverton, Oregon, Pettit holds a bachelor’s degree in Chemical Engineering from Oregon State University, Corvallis, and a doctorate degree in Chemical Engineering from the University of Arizona, Tucson. Prior to his career with NASA, Pettit worked as a staff scientist at the Los Alamos National Laboratory in New Mexico.
For more than two decades, humans have lived and worked continuously aboard the International Space Station, advancing scientific knowledge, and making research breakthroughs that are not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA is able to focus more of its resources on deep space missions to the Moon and Mars.

Launched less than two months ago, ESA’s EarthCARE satellite has already returned images from two of its four instruments. Now, it has also delivered the first images from its multispectral imager, showcasing various types of clouds and cloud temperatures worldwide. This instrument is set to add valuable context to the data from EarthCARE’s other instruments.
