Many ships are skirting the Red Sea in the midst of Houthi attacks, but the ones attempting the dangerous journey are likely to be older and carrying unknown insurance. Bloomberg @markets reports on how these ships threaten the environment and other structures.

This is why cloud masks are actually the hardest problem in remote sensing

Volcano pictures are cool, but Umbra's licensing is even cooler. You can put this picture on a calendar or a tshirt, or incorporate it into a scientific article and publish it, and make money from it. And pay us nothing. Our standard license is Creative Commons (CC BY 4.0), which means that you can do most anything with our imagery, including remixing it, reselling it, publishing it, sharing it, etc. as long as you attribute it to Umbra. We're gonna help you with some fun material to work with to try this out if you check out our open data program, including a mountain (ba dum tss!) of volcano data here: umbra.space/open-data

Detailed analysis by @RUSI_org from dozens of satellite images tracking two cargo ships running from North Korea to Russian ports, transferring to rail and likely onwards towards Ukraine. Switching off vessel's AIS only further draws attention rusi.org/explore-our-researc…

An excellent summary of UK’s situation in relation to @copernicusEU, probably the most valuable EO asset for the benefit of all of 🌎🌍🌏. To invest in this programme is to literally invest in the future. Read the thread👇

Our Gofundme goes on...chasing the goal line to build a new weather satellite imagery antenna with associated kit. Find that rapidly inflation-eaten note in your pocket and send it our way digitally so we can support present and future weather research! gofundme.com/f/dundee-satell…

The @IPCC_CH climate report published today contains a curious footnote “do not quote, cite or distribute”. This is because it’s an approved draft now only subject to copy editing & consistency edits ahead of final publication. You’re welcome.

Our calculations have discovered the three 'norths' will combine for the first time in history this week🧭 True north, magnetic north and grid north will combine at a single point - starting at Langton Matravers, a village just west of Swanage #3Norths

NovaSAR Research Programme - opportunity to conduct research exploiting S-band #NovaSAR satellite data @SatAppsCatapult Would be nice to see what can be done in vegetation/landcover domain, not just another ship detection algorithm sa.catapult.org.uk/opportuni…

Here @SatAppsCatapult for the #NovaSAR satellite workshop. @UKHO presenting our initial findings on the utility of #SAR for detecting and locating maritime aids to navigation (buoys, beacons). A simple practical application without the maths😏

Remotely joining @SatAppsCatapult to hear about one of the lesser known #SAR systems … the UK’s NovaSAR. Been up since 2018 … but few have heard of it, let alone used it … time to find out! 😀

Our launch date is set! 🌎 @NASA's Surface Water Ocean Topography mission, or SWOT, will provide the first global survey of Earth's surface water. It's scheduled for launch on December 5, 2022. go.nasa.gov/3CxuSle #TrackingWorldWater

Apparently the third #Airbus #SolarPowered #Zephyr UAV to be lost whilst in flight, but this @RAeSTimR article also contains a full and excellent description of both Zephyr #HAPS concept...and their vulnerabilities.

Hazarding a guess here, but I suspect that in 1818 options for the 17 year old Ruth to pursue geography beyond the confines of the drawing room were extremely limited? And that’s for those few who had the luxury of a drawing room?
