If anyone doesn't get the joke...

The clip is from the UK comedy series Father Ted, actor Frank Kelly died recently, and had a certain...attitude.
All good stuff, well, it made me laugh.

Final phrase is intended re #17 above.

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

How reflective is the SAR antenna on the main payload? Will this be easy to track in the evening sky?

Interesting experiment.

28 April 2016
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.

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.

Quote:
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.
