Sentinel-2 explores night vision
After more than 10 years in orbit, the first Copernicus Sentinel-2 satellite, Sentinel-2A, is still finding new ways to contribute to Earth observation. With its younger siblings, Sentinel-2B and Sentinel-2C, now leading the mission’s core task of delivering high-resolution, ‘camera-like’ images of Earth’s surface, the European Space Agency is pushing Sentinel-2A beyond its original remit.
In recent trials, this elderly satellite was even switched on at night to see how it would perform in the dark – and the results have been strikingly positive, offering encouraging news for the follow-on Copernicus Sentinel-2 Next Generation mission, currently in development.

Coverage, Briefing Set for NASA’s Artemis II Moon Rocket Roll to Pad
NASA’s integrated SLS (Space Launch System) rocket and Orion spacecraft for the Artemis II mission is inching closer to launch – literally.
The agency is targeting no earlier than 7 a.m. EST, Saturday, Jan. 17, to begin the multi-hour trek from the Vehicle Assembly Building to Launch Pad 39B at NASA’s Kennedy Space Center in Florida.
A pre rollout mission news conference, live feed of rollout, and a media gaggle will stream on NASA’s YouTube channel. Individual streams for each of these events will be available from that page. Learn how to stream NASA content through a variety of online platforms, including social media.
The time of rollout is subject to change if additional time is needed for technical preparations or weather.
All times are Eastern. Events are as follows:
Friday, Jan. 16:
12 p.m.: Artemis II Rollout, Mission Overview News Conference
- John Honeycutt, Artemis II mission management team chair
- Charlie Blackwell-Thompson, Artemis launch director, Exploration Ground Systems
- Jeff Radigan, Artemis II lead flight director, Flight Operations Directorate
- Lili Villarreal, landing and recovery director, Exploration Ground Systems
- Jacob Bleacher, chief exploration scientist, Exploration Systems Development Mission Directorate
Saturday, Jan. 17:
7 a.m.: Rollout, Artemis II Live Views from Kennedy Space Center feed begins
9 a.m.: Artemis II Crew Rollout Media Event
- NASA Administrator Jared Isaacman and the Artemis II crew, including NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, will answer questions about their preparations and the mission for media in-person at the countdown clock.
NASA’s crawler-transporter 2 will carry the 11-million-pound stack at about one mile per hour along the four-mile route from the Vehicle Assembly Building to Launch Pad 39B, on a journey that will take up to 12 hours.
To participate in the news conference by telephone, media must RSVP no later than two hours before the start to: ksc-newsroom@mail.nasa.gov.
These events will be open in-person only to media previously credentialed for launch. The deadline has passed for in-person accreditation for Artemis II events at Kennedy.
Rollout to the pad marks another milestone leading up to the Artemis II mission. In the coming weeks, NASA will complete final preparations of the rocket and, if needed, rollback SLS and Orion to the Vehicle Assembly Building for additional work. While the Artemis II launch window opens as early as Friday, Feb. 6, the mission management team will assess flight readiness after the wet dress rehearsal across the spacecraft, launch infrastructure, and the crew and operations teams before selecting a launch date.
Follow NASA’s Artemis blog for mission updates.
Through Artemis, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars.

New York–Newark–Jersey City Metropolitan Area
The New York–Newark–Jersey City Metropolitan Statistical Area, which spans 23 counties across New York, New Jersey, and Connecticut and has a population of about 19.9 million, is pictured at approximately 3:29 a.m. local time Dec. 20, 2025, from the International Space Station as it orbited 262 miles above the Atlantic coast.
Crew members aboard the orbital lab have produced hundreds of thousands of images of the land, oceans, and atmosphere of Earth, and even of the Moon through Crew Earth Observations. Their photographs of Earth record how the planet changes over time due to human activity and natural events. This allows scientists to monitor disasters and direct response on the ground and study a number of phenomena, from the movement of glaciers to urban wildlife.
