Interesting experiment.

Launched on 25 April from Europe’s Spaceport in French Guiana, Sentinel-1B has produced its first images only two hours after the radar was switched on – a record time for a space radar.

One of the satellites launching with this is testing that gravitational mass = inertial mass.

I can't help thinking that this experiment will only give the desired results if it were in geostationary orbit. ?

In the early hours of 30 October 2016, a 6.5 magnitude earthquake struck central Italy. Scientists from Italy’s Institute for Electromagnetic Sensing of the Environment combined a Copernicus Sentinel-1B radar image from 26 October with a Sentinel-1A radar image from 1 November to analyse ground displacements caused by the quake.
The results show ground deformations extending across about 130 sq km with a maximum displacement of at least 70 cm (in the direction of the satellite), in the area of Castelluccio.

The Copernicus Sentinel-1 satellite mission is monitoring the growing crack in Antarctica’s Larsen-C ice shelf. When the ice shelf breaks off or ‘calves’, it will create one of the largest icebergs ever recorded – but exactly how long this will take is difficult to predict.
This animation demonstrates how scientists analyse radar data from Sentinel-1 to monitor the crack. This includes combining radar images to create an ‘interferogram’.

The crack in the Larsen C Ice Shelf that looks set to spawn a giant berg has suddenly forked.
Satellite imagery of the 180km-long fissure acquired in recent days shows a clear branching behaviour at its tip.
...
Sentinel-1 continues to watch the crack. The length of the polar night is getting so long now as the Antarctic moves into winter that most optical satellites have given up gathering data.
Only spacecraft with radar instruments, like Sentinel-1, can hope to see the ice surface in darkness.

Not directly Sentinel news, but close!

Documentary on BBC 2 tonight. Horizon, so might be worth recording.

On 20 May, over a million tonnes of dirt and rock buried part of California’s Highway 1 along the Pacific coastline in the state’s Big Sur region. In addition to cutting off the route, the landslide added some 5 hectares of land to the shoreline.
Sentinel-1’s radar shows that the ground that slid down the mountain was moving in the two years before the landslide.

One of the biggest icebergs ever recorded has just broken away from Antarctica.
The giant block is estimated to cover an area of roughly 6,000 sq km; that's about a quarter the size of Wales.
An US satellite observed the berg on Wednesday while passing over a region known as the Larsen C Ice Shelf.
Scientists were expecting it. They'd been following the development of a large crack in Larsen's ice for more than a decade.
The rift's propagation had accelerated since 2014, making an imminent calving ever more likely.

"about a quarter the size of Wales." Wales is a small colony on the West of England...

I wonder how long it'll take to melt...!

"about a quarter the size of Wales." Wales is a small colony on the West of England...

In reality Wales is a unit of deforestation.
:leaving:

 

[Notebook]

Wow, thought i was risking it....
Strange, we did have a larger colony much, much, much further to the West. We haven't heard from it for a long time. Hope they are ok.

You mean Canada ? Trees are going to become scarce there given the lumbermills output...

Anyways it seems that Sentinel is doing good science ! :thumbup:

 

[Notebook]

Canada..it may well call itself that, good to hear from you. Do you have any news of another colony to your South?

Well, the article I read said the iceberg was the size of Delaware. Maybe that's the colony you refer to.

Last time I checked the Dupont family owned half of it.

The iceberg has been sold already? I was saving up for that.

Title Giant berg on the move
Released 20/09/2017 5:04 pm
Copyright contains modified Copernicus Sentinel data (2017), processed by ESA, CC BY-SA 3.0 IGO
Description
Witnessed by the Copernicus Sentinel-1 mission on 12 July 2017, a lump of ice more than twice the size of Luxembourg broke off the Larsen C ice shelf, spawning one of the largest icebergs on record and changing the outline of the Antarctic Peninsula forever. Over the following two months, systematic observations from Sentinel-1 showed that the A68 berg remained close, buffeting back and forth against the ice shelf. It was unclear what would happen to the berg because they can remain in one place for years.
However, the mission has revealed that A68 is now on the move and drifting out to sea. Images from 16 September show that there is a gap of about 18 km as the berg appears to be turning away from the shelf.

25 September 2017
Engineers have been at Russia’s Plesetsk launch site for a month now, ticking off the jobs on the ‘to do’ list so that the Copernicus Sentinel-5P satellite is fit and ready for liftoff on 13 October. With the satellite now fuelled, the team has passed another milestone.
Fuelling a satellite is a particularly delicate operation. Hydrazine is extremely toxic so only a few specialists wearing ‘scape’ suits remain in the cleanroom.

They were doing great. And then they took an anthem to the knee...
