Acquired on 13 April 2014 at 09:03 GMT (11:03 CEST) this image covers parts of Pine Island Glacier and Thwaites Glacier in West Antarctica. This image is among the first from Sentinel-1A, which was launched on 3 April. It was acquired in ‘Interferometric Wide Swath’ mode with a swath width of 250 km and in single polarisation. With Pine Island Glacier in a state of irreversible retreat, the Sentinel-1 mission is set to be an excellent tool for monitoring such glaciers as well as for providing timely information on many other aspects of the polar regions, such as sea ice and icebergs.
Testing the deployment of the Sentinel-1A radar antenna in the cleanroom at Thales Alenia Space in Cannes, France, on 21 January 2014. As the satellite is designed to operate in orbit, it is hung from a structure during tests to simulate weightlessness.
The Synthetic Aperture Radar, or SAR, will provide an all-weather day-and-night supply of imagery for services such as the monitoring of Arctic sea-ice extent, routine sea-ice mapping, surveillance of the marine environment, monitoring land-surface for motion risks and mapping to support humanitarian aid and crisis situations.
Sentinel-1A – the first satellite built for the Copernicus environmental monitoring programme – is foreseen for launch in the spring of 2014 from Europe’s spaceport in Kourou, French Guiana.

Soyuz VS07 was transferred from the preparation building MIK to the Soyuz launch zone of the Europe’s Spaceport in French Guiana, on 31 March 2014.
The vehicle was rolled out horizontally on its erector from the MIK to the launch zone and then raised into the vertical position.
Soyuz VS07 will lift off on 3 April 2014. The rocket will carry Sentinel-1, the first in the family of Copernicus satellites.
This satellite will be used to monitor many aspects of our environment, from detecting and tracking oil spills and mapping sea ice to monitoring movement in land surfaces and mapping changes in the way land is used. It will also play a crucial role in providing timely information to help respond to natural disasters and assist humanitarian relief efforts.

This interferogram of the northern coast of Norway combines two radar images acquired by Sentinel-1A on 11 August and 23 August 2014. Although Sentinel-1A is still being commissioned, this new result demonstrates how useful it will be to map the shape of the land and monitor ground movement. Synthetic aperture radar interferometry – or InSAR – is a technique where two or more satellite radar images acquired over the same area are combined to detect large-scale surface changes. Small changes on the ground cause changes in the radar signal phase and lead to rainbow-coloured fringes in the interferogram. In this case, the image mainly denotes differences in topography.
The Lyngen Alps are featured on the right where mountains up to 1800 m rise from the sea. Since the area is particularly prone to landslides, it is closely monitored. Large landslides could shift rock into the sea suddenly, which could potentially create tsunami-like waves. In 1810, such a wave destroyed a village, and history shows that this kind of natural disaster occurs a couple of times every 100 years in Norway. InSAR is already an important tool for nationwide rockslide hazard mapping by Norwegian authorities. The unprecedented coverage offered by Sentinel-1 will significantly increase the value of InSAR data for this purpose.

The Copernicus Sentinel-1B satellite takes us over one of the most active volcanos in the world: Mount Mayon on the island of Luzon in the Philippines.
Luzon is the biggest island in the Philippines and home to most of the country’s active volcanoes. This volcanism is associated with plate tectonic processes where the floor of the South China Sea is being drawn down into the mantle along the Manila Trench, which is to the west of the island. The image just shows part of the southern end of this large island, but features no less than five volcanoes.
While Mount Mayon – the most southerly volcano in the image – is famous not only for being perfectly formed, but also for being one of the most active in the world, the other four volcanoes in the image are actually either dormant or extinct.Dubbed a perfect volcano because of its symmetry, Mount Mayon has a classical conical shape, built up by many layers of hardened lava. It erupts frequently with the most recent eruption occurring in January this year.
This image was captured on 16 January 2018 and while satellite radar isn’t typically used to detect hot lava flows, the way it has been processed reveals a pink line running down the southeast flank of the volcano that matches the flow of lava in optical images from satellites such as Sentinel-2. The predominant bright green in the image corresponds to vegetation, the lighter green and pink to towns and the blue to cultivated fields.
While the Sentinel-1 radar mission is used for a myriad of everyday applications, it is also used to detect ground movement, which is essential for monitoring shifts from earthquakes and volcanic uplift.
This image is also featured on the Earth from Space video programme.

Only launched two months ago and still in the process of being commissioned for service, the Copernicus Sentinel-1C satellite has, remarkably, shown how its radar data can be used to map the shape of Earth’s land surface with extreme precision. These first cross-satellite ‘interferometry’ results assure its ability to monitor subsidence, uplift, glacier flow, and disasters such as landslides and earthquakes.
This cross-satellite interferogram is of the Atacama Desert plateau in northern Chile and was generated from images acquired just one day apart, by Sentinel-1A on 19 January and Sentinel-1C on 20 January. The ‘grey-scale amplitude’ radar image is for reference.

The multilayer insulation is very important because it keeps the satellite at an ambient temperature by protecting it from the fierce heat of the Sun and the cold temperature of space as orbits Earth.
