Cat 5 Hurricane Polo, seen 22nd Sept by the OLCI instrument aboard Sentinel-3B. Polo rapidly intensified and now has ferocious winds OLCI is designed to look at the Earth's oceans, seas and lakes - but thanks to a great design is also super useful for monitoring weather too @esa.int @eumetsat.int

Late on Monday night, @esa.int successfully launched FLEX and Sentinel-3C aboard an Avio VEGA-C rocket. Two really exciting missions, am super happy to see them in orbit and am looking forward to working with Sentinel-3C as we get it ready for operations. 😃

Simon Proud @simonsat.bsky.social · 08/09/2026

In six days, we will launch the FLEX and Sentinel-3C satellites! S3C will ensure we can provide high quality climate data and information to support distaster response into the next decade. Can't wait to see these two beautiful satellites in space 🚀 @esaearth.esa.int @eumetsat.int @ec.europa.eu

Drought conditions across Western Europe - the effects of our hot, dry, summer so far These two pics were taken by the Copernicus Sentinel-3 mission ~7 weeks apart. The effects of limited rainfall and hot, clear, weather are clearly visible: Much of Western Europe is looking desert-like from space.

Sentinel-2 and wildfires: These last few days, a devastating wildfire has been raging near Los Gallardos in Spain - sadly resulting in multiple deaths and significant destruction. This pic was taken on 10th July by Sentinel-2A, the scale of the fire clearly visible.

Today in AI is rubbish...it decided I should have "clever" code rather than "valid" code. And we're gonna roll this stuff out to help teach schoolkids, eh?

Simon Proud @simonsat.bsky.social · 03/06/2026

For those of you interested in our Sentinel-2 night imaging campaign, the data is now ready: freely and openly available! Details: sentinels.copernicus.eu/web/sentinel... Am hoping this data is useful to the EO community, and happy to hear your feedback! @esa.int @esaearth.esa.int @ec.europa.eu

Simon Proud @simonsat.bsky.social · 10/04/2026

I decided to give Copilot a go, to help with a simple task. Have instantly broken it, and now copilot is sad 😂 Oh well, no AI for me!

Breathtaking! As a child I wanted to travel to the Moon...as an adult, my height worked against me and my travel plans - but I was hooked on space anyway! Delighted to see a joint American + European success on Artemis II! @esa.int supplying the service module. 💪🛰️

Simon Proud @simonsat.bsky.social · 04/03/2026

Dual use: If we like it or not, all civilian sats have defence-related uses. This video shows the Russian Arctic Metagaz LNG carrier exploding after reportedly being hit by Ukranian drones. It comes from @eumetsat.int's Meteosat-12, a weather satellite. Weather is civil, but we see so much more.

Earlier in Feb, Cyclone Gezani hit Mozambique, sadly resulting in fatalities anddamage to buildings Here, two Sentinel-2 pics show the impacts: Flooding inland, and a hugerunoff heading into the ocean. S2 is critical for disaster response - and we plan to improve its value for the next gen mission!

Simon Proud @simonsat.bsky.social · 19/01/2026

In December, we ran a campaign to switch the Sentinel-2A satellite on at night over some specific areas. The goal was to provide data to help me work out how useful night imaging capabilities would be for next gen Sentinel-2...and the results are wonderful! Read more: www.esa.int/Applications...

Simon Proud @simonsat.bsky.social · 06/01/2026

Kinda shocked at how the Netherlands copes with a little bit of snow. Every train cancelled, roads not clear, people "stocking up on supplies in case shops close". But, tbh, im glad to know its not just the UK that cant handle winter weather. I thought blighty was the exception 😂

Simon Proud @simonsat.bsky.social · 21/12/2025

The traditional end of year collab between @esa.int , @eumetsat.int, @wmo-global.bsky.social and me. I love making these pics...MTGsending back beautiful data as always! 😍 These four are 06UTC on: 19/12, 22/09, 21/06 and 20/03 Nice seeing how the sunlight moves around our planet during the year.

Simon Proud @simonsat.bsky.social · 06/11/2025

Huge dust storms in Pakistan, seen by the @esa.int / @ec.europa.eu Sentinel-2B and Sentinel-3B satellites on 4th November. Neither satellite was designed to monitor dust plumes, so it's impressive how much information they give us about the detail and extent of these storms!

Along the N. Coast of Alaska, winter is closing in. These pics ages, from the Copernicus Sentinel-2 mission, were taken just two weeks apart. Heavy snowfall on land, and the beginnings of ice on sea. Soon, the sun will be too low and Sentinel-2 will stop acquiring images until Springtime.

Simon Proud @simonsat.bsky.social · 28/10/2025

Insane. This is Hurricane #Melissa seen right near landfall by the Copernicus / @esa.int Sentinel-2C satellite. It looks so beautiful, and it's hard to comprehend how much destruction a hurricane like this can cause. Best wishes to everyone in Jamaica.

Simon Proud @simonsat.bsky.social · 28/10/2025

17 hours of #Hurricane #Melissa seen from space compressed into 9 seconds. Weather sats are vital for monitoring and forecasting Hurricanes. Without them, our forecasts would be much worse - increasing the danger posed by these monsterous storms. Data: NOAA / GOES-19 Video: ESA / Simon Proud

It was great to be at @thalesaleniaspace.bsky.social last week to discuss the SIRIUS mission that is under consolidation as one of @esa.int's future SCOUT missions. SIRIUS will examine land surface temperature, with a focus on urban heat islands and unique data for evapotranspiration models.

Simon Proud @simonsat.bsky.social · 30/09/2025

Here are two images from the @esa.int / @ec.europa.eu Sentinel-2 mission showing the city of #Salalah in Southern Oman. One pic from June, before the rainy season, and one from this week, after the rains. The hills around the city transform into a lush green landscape!

0265

Simon Proud @simonsat.bsky.social · 25/09/2025

An amazing change in the colour of the sea due to #Typhoon #Ragusa. The first pic was taken by the @esa_earth Sentinel-2 mission a few days before the typhoon, the second pic taken after the typhoon, just a few hours ago.

Simon Proud @simonsat.bsky.social · 05/09/2025

Nice to receive a little present from our @esa.int Sentinel-2 team, a Lego S2 satellite 😄

Simon Proud @simonsat.bsky.social · 19/08/2025

Am taking some time for relaxation in the Alps, so apologies for being slow to respond to messages and comments. Will be back in the world of space-based Earth Observation soon, but for now im enjoying EO at slightly lower altitudes 🙂

Simon Proud @simonsat.bsky.social · 02/08/2025

To me, the Netherlands is remarkably anthopogenic place, nature is subjugated, everything is concrete and construction: Why have a garden when you can have space for a second car? Glad to have found a house that retains some nature.

Simon Proud @simonsat.bsky.social · 18/07/2025

Nice to visit Thales Alenia Space in Madrid this week to discuss future satellite missions. Thanks for the tour of the clean room! Lots of exciting work going on 😃

Simon Proud @simonsat.bsky.social · 09/07/2025

Large #wildfires burning in Syria, seen yesterday by the Copernicus / @esaearth.esa.int Sentinel-2 mission. As well as the fires themselves, you can see a huge region that's already been burned - all that Brown-coloured bit in the middle.

Simon Proud @simonsat.bsky.social · 02/07/2025

Satellite sees satellite! 😮 The @noaa.gov GOES-18 satellite saw @eumetsat.int's MTG-S1 satellite as it blasted off from Florida last night. See that little bright dot in the middle of the image? That's the @spacex.extwitter.link rocket!

Simon Proud @simonsat.bsky.social · 26/06/2025

Today we signed the study contract for our @esa.int SCOUT missions. Am excited to be the science officer for SIRIUS, one of the missions, that aims to explore urban heat islands. These missions are fast, with compressed development, and I'm looking forward to seeing the progress! 🚀🛰

Simon Proud @simonsat.bsky.social · 24/06/2025

Day 2 of Living Planet! #LPS25 Do you want to learn about what's new with the next generation of Sentinel-2 and Sentinel-3? Come along to our session at 11.30, room E1!

010

Simon Proud @simonsat.bsky.social · 23/06/2025

Ever wondered what's inside a satellite? Here's a nice simple example from Airbus about what's inside Sentinel-2!

083

Simon Proud @simonsat.bsky.social · 23/06/2025

Arriving at a very sunny #LPS25! Keen to talk to as many people as possible, especially about sentinel 2 and 3. Let me know what you like, what you want, what you do!

0100

Simon Proud @simonsat.bsky.social · 23/06/2025

Are you going to be at Living Planet #LPS25 today? If so, join us between 14:00 and 17:45 for two sessions celebrating 10-years of Sentinel-2! Come listen to some of the highlights, and get insights into what comes next. And, if that doesn't tempt you, there will also be cake! 😀

0121

Simon Proud @simonsat.bsky.social · 22/06/2025

Back in Vienna, back at the UN! Now time for #LPS25 🚀

Simon Proud @simonsat.bsky.social · 20/06/2025

Preparing for #LPS25 by putting together some beautiful images from the Sentinel-3 mission. Check out all these wonderful pictures of our planet, all taken by S3 within the last 24 hours! Nice example of the excellent collaboration between @esa.int , @eumetsat.int and @ec.europa.eu!

Simon Proud @simonsat.bsky.social · 17/06/2025

Nice overview by Jacob from the Danish Meteorological Institute at the @ghrsst.bsky.social symposium about the challenges of retrieving data on ice surface temperature in the arctic. Lots of progress, but still lots of work to be done...

061

Simon Proud @simonsat.bsky.social · 16/06/2025

Happy to be at the @ghrsst.bsky.social meeting in beautiful Copenhagen. Looking forward to talking to all the scientists about our next generation of @esa.int / Copernicus Sentinel missions!

Simon Proud @simonsat.bsky.social · 13/06/2025

Two large flashes visible in satellite data of Israel over the past hour. One is inland, the other offshore. Suspect the offshore one is gas flaring from an oil platform as a precaution against attack...

031

Simon Proud @simonsat.bsky.social · 05/06/2025

Exploring somewhere new on today's visit to @eumetsat.int! 🛰📡

Simon Proud @simonsat.bsky.social · 30/05/2025

On 28th May the Birch glacier, above the Swiss village of #Blatten collapsed - sending debris into the village, destroying much of it. Today, the #Sentinel2 satellite overflew Blatten, letting us look at how the glacier evolved right up to the collapse. Really shocking scenes...

071

Simon Proud @simonsat.bsky.social · 09/05/2025

As part of our preparation for potential future missions, we switched the @esaearth.esa.int / Copernicus Sentinel-3A satellite to take measurements at night. This is what it saw, look at all those gas flares in Iraq! Thanks to @eumetsat.int for setting up these night-time observations. 💪

Something seems incompatible here...

Simon Proud @simonsat.bsky.social · 25/04/2025

This is over 1,300 years old, travelled all the way from Egypt to India and I hold it in the palm of my hand. Historical artefacts blow my mind!

Simon Proud @simonsat.bsky.social · 15/04/2025

Delighted to have been at the @esa.int security conference this week. Space is crucial for defence and civil security, and it's been super interesting to hear from European decision makers, industry and security experts. Now, lots to do - but the European direction is set.

Unprecented wildfires are burning in South Korea, killing, sadly, at least 24 people and causing widespread damage: www.bbc.com/news/article... The plume of smoke caused by the fires is clearly visible from space, seen here by S. Korea's GK2A weather satellite.

Simon Proud @simonsat.bsky.social · 20/03/2025

Today is the #equinox, when the sun appears directly over the equator. Throughout the year, the sun appears to move North and South, changing how much daylight we get. Here's how that looked over the past year, thanks to Japan's #Himawari weather satellite.

0258

Simon Proud @simonsat.bsky.social · 17/03/2025

Strong radar signatures in today's Copernicus #Sentinel1 overpass of Crimea. All those bright diagonal lines indicate something interfering with the satellite radar signal. In this case, ground-based Russian air defence assets.
