The launch marketing campaign of the subsequent satellite tv for pc to affix the Copernicus Sentinel-1 mission is progressing on schedule for launch on Tuesday, 4 November, on board an Ariane 6 rocket.
The Sentinel-1 mission delivers radar photos of Earth’s floor, performing in all weathers, day-and-night. This service is important for catastrophe response groups, environmental businesses, maritime authorities, local weather scientists – and different customers who rely upon frequent updates of crucial knowledge.
Sentinel-1D is the mission’s subsequent satellite tv for pc and is ready to affix its sibling, Sentinel-1C. When absolutely commissioned, it should substitute Sentinel-1A, which has been in orbit for 11 years, nicely past its deliberate lifetime.
Sentinel-1D and -1C will generate knowledge and imaging utilizing a C-band artificial aperture radar (SAR) instrument, which captures high-resolution imagery of Earth’s floor. They’re additionally outfitted with an Automated Identification System (AIS) instrument to enhance detection and monitoring of ships. When each are operational, extra frequent AIS observations will likely be potential.
The spacecraft Flight Readiness Assessment happened final week, paving the way in which for fuelling of Sentinel-1D.
The mission’s Undertaking Supervisor, Thibaut Decoopman, defined that the group is now finalising the satellite tv for pc configuration for launch, previous to getting ready the spacecraft for encapsulation. He mentioned, “Because it arrived in French Guyana, Sentinel-1D has efficiently accomplished the final integration steps and undergone the purposeful exams. The satellite tv for pc is now fuelled and in good well being, completely on-time for mating onto the launcher, because of the continual dedication of our trade colleagues and ESA group members.”
The satellite tv for pc will likely be encapsulated on Friday, 24 October.
Concerning the Copernicus Sentinel-1 mission
The mission is a part of the Copernicus household of Sentinel satellites, developed by the European Area Company (ESA). Copernicus is the Earth remark element of the European Union’s Area Programme and is the biggest environmental monitoring programme on this planet.
The information offered by the Sentinel missions kind the idea of the operational Copernicus info providers, serving to to handle the atmosphere, monitor and react to local weather change and safeguard lives. Copernicus gives open-access knowledge used worldwide.
About Ariane 6
Ariane 6 is Europe’s heavy launcher and a key element of ESA’s efforts to ensure autonomous access to space for Europe’s citizens. Its modular and versatile design allows it to launch missions into low-Earth orbit as well as those destined to go much further into deep space. Standing more than 60 metres tall, Ariane 6 can weigh almost 900 tonnes when launched with a full payload.
