Sentinel-1B launched to finish radar pair

The second Sentinel-1 satellite – Sentinel-1B – was launched currently to yield some-more ‘radar vision’ for Europe’s environmental Copernicus programme.

Sentinel-1B carried off on a Soyuz rocket from Europe’s Spaceport in Kourou, French Guiana, during 21:02 GMT (23:02 CEST), separating from a rocket’s Fregat top theatre 23 min 35 sec later.

Sentinel-1B joins a matching twin, Sentinel-1A, in circuit to broach information for countless services, from monitoring ice in frigid seas to tracking land subsidence, and for responding to disasters such as floods.


“The launch of Sentinel-1B outlines another critical miracle as this is a initial constellation we have realised for Copernicus,” pronounced ESA’s Director General Jan Woerner.

“Orbiting 180° apart, a dual satellites optimise coverage and information smoothness for services that are creation a step change in a approach a sourroundings is managed.”

Both satellites lift an modernized radar that images Earth’s aspect by cloud and sleet regardless of either it is day or night.

During a launch, a satellite’s 12 m-long radar receiver and dual 10 m-long solar wings were folded adult to fit into a Soyuz rocket’s protecting fairing.

The solar wings and radar open together in a clever method that will take about 10 hours to complete.

Now that Sentinel-1B has been placed safely in orbit, a group of controllers during ESA’s operations centre in Germany will safeguard that all is operative rightly and elect a satellite for operations.

Volker Liebig, ESA’s Director of Earth Observation Programmes, said, “We have seen some noble formula from Sentinel-1A. Only dual weeks ago, for example, it prisoner images of vast icebergs violation divided from Antarctica’s Nansen ice shelf.

“Given that Antarctica is streamer into winter now and illumination hours are removing shorter, radar images are critical to see what changes are holding place.

“With Sentinel-1B in circuit we will accept double a volume of information and grasp tellurian coverage in 6 days.

“This is a fourth satellite that we’ve launched for Copernicus in only dual years and this launch is positively a special impulse since it completes a Sentinel-1 constellation.”
The launch of Sentinel-1B also supposing an event to give other smaller satellites a float into space.

Three CubeSats took advantage of today’s launch. These tiny satellites, any measuring only 10×10×11 cm, were grown by teams of university students by a ‘Fly Your Satellite!’ programme, run by ESA’s Education Knowledge Management Office in tighten partnership with European universities.

The 3 CubeSats are: OUFTI-1 from a University of Liege, Belgium, e-st@r-II from a Polytechnic of Turin, Italy, and AAUSat-4 from Aalborg University, Denmark.

“Importantly, a programme is assisting to teach a subsequent era of scientists and engineers by transferring ESA knowhow in designing, building, testing, rising and handling satellites,” pronounced Piero Galeone, ESA’s Head of a Tertiary Education Unit.

“This approach we are assisting to figure a space workforce of a destiny by enabling students to knowledge a full lifecycle of a genuine space plan according to ESA’s standards.”
