Sentinel-1 is the first of the Copernicus Programme satellite constellations conducted by the European Space Agency. [4] The mission was originally composed of a constellation of two satellites, Sentinel-1A and Sentinel-1B , which shared the same orbital plane.
Sentinel-1A is a European radar imaging satellite launched in 2014. It is the first Sentinel-1 satellite launched as part of the European Union 's Copernicus programme . The satellite carries a C-band Synthetic Aperture Radar which will provide images in all light and weather conditions.
Return to flight for Vega-C following the VV22 launch failure. Third Sentinel-1 satellite. Originally intended to launch on the Russian Soyuz launch vehicle; due to geopolitical factors, ESA moved Sentinel-1C to a Vega-C launch. 6 December 03:14 [242] [243] Simorgh: Semnan LP-2: ISA: Saman-1: ISA: Low Earth: Space tug: In orbit: Operational ...
This article lists orbital and suborbital launches planned for the second half of the year 2025, including launches planned for 2025 without a specific launch date. For all other spaceflight activities, see 2025 in spaceflight. For launches in the first half of 2025, see List of spaceflight launches in January–June 2025.
Copernicus is the Earth observation component of the European Union Space Programme, managed by the European Commission and implemented in partnership with the EU member states, the European Space Agency (ESA), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), the European Centre for Medium-Range Weather Forecasts (ECMWF), the Joint Research Centre (JRC ...
This is a timeline of known spaceflights, both crewed and uncrewed, sorted chronologically by launch date. Due to its large size, the timeline has been split into smaller articles, one for each year since 1951. There is a separate list for all flights that occurred before 1951.
Sentinel-1B was a European radar imaging satellite launched on 25 April 2016. It is the second of two original satellites in the Sentinel-1 constellation, part of the European Union's Copernicus programme on Earth observation. The satellite carries a C-SAR sensor, capable of providing high-resolution imagery regardless of weather conditions.
Vega C, like its predecessor, is designed to launch small satellites for scientific and Earth observation missions to polar and sun-synchronous low Earth orbits. [5] The reference Vega C mission places a 2,300-kilogram (5,100 lb) spacecraft into a 700-kilometre (430 mi) polar orbit, representing an 800-kilogram (1,800 lb) or 60% increase over ...
