Radar satellites can see at night and through clouds They also can detect millimetre changes in some cases, from space (!) But I've found them really counter-intuitive, so I spent the last 6 months working on a video explaining how they work Watch:

There are a lot of people I need to thank for this, this was probably the biggest thing I've made so far - @DarrenMuff for sharing the excitement and answering my dumb questions - @umbraspace for their open data program, meaning 80% of all the images in the video are from them - Thomas Ager for writing what I think is the best book on SAR out there, having a long conversation with me, and proof-reading my script - @boxMica for making such cool SAR renders, and letting me use them in this video - Jason Wang for helping me actually make this, and being a great supporter behind the scenes - @ICEYEfi where I learned a bunch of what I know now and having so many cool animations!

@umbraspace Great overview and video. I need to learn your video skills, yet unless ai can do it I can’t seem to find that time yet.

@umbraspace Thanks Nathan! It's like many things: repetition and putting a ton of hours into it :)

Question regarding the virtual 100 km virtual antenna: assuming the microwave travels with light speed, the send-receive delay time should be about 3 ms, so not enough time for the satellite to change position. Probably the send-direction is continuously updated?

That's a good question, I'm not quite sure My hunch would be that you need to take that into account to get to higher resolution & better signal to noise ratio I'd defer to some of the folks who actually work on this, thinking of @DarrenMuff or @MasterActual ?

Really wasn’t expecting to talk about this last night, but getting more comfortable at doing so over time. Don’t beat down on the disabled, lift them up. They have a resilience and determination that employers, and the state, can only benefit from.

Please 🇳🇬 don't see every Northerner as a bandits. "Sunday Igboho’s Iru Ekun Security Network claimed they captured some suspected bandits who fired back at them" *My Questions * (1) How did they know they are the ones that fired back at them ? (2) They said they caught them with knives , so they fired at them with knives? (3) Reference to the video, nothing criminality was found on them , so they think bandits can be captured that easily ?

I found a box some GE soft white incandescent light bulbs at the Habitat for Humanity a few months ago. Frankly, I am burning through them, though they last longer than I thought they did. Is there a way we can smuggle them in? Are there some places around the world that still make incandescent bulbs? The bulbs reminded me of that GE commercial from the 1980s. Again the question. Why can we not have light bulbs that are easy on the eyes? And why can't commercials just straightforwardly present products in a wholesome, simple way?

Dealing with a mboch in Kenya is a nightmare so I can only imagine what foreigners go through after shipping them from Kenya. Check the first video of a Kenyan in the Middle East akijichizisha and it's only a fellow Kenyan who can deal with her madness, then the 2nd video of a Kenyan casually explaining what they do after being sponsored to go work in the Middle East.

Regime spokesman, recently: “Jews can never fight a war. The moment you scream at them, they just run away. They bark like dogs, but when they see the stick, they run and hide.” How did that work out? 🤣

lando: “i've been a little bit on the back foot from the start of the weekend, just not really done enough laps and a lot of issues on the car, which we wish we had less of. they can happen, it does happen. so trying to work through them and in some ways it's an expectation that at the start of the year you just try and minimise them. but luck's not particularly not been on my side so far this weekend and including again then in qualifying with the debris on track and breaking my front wing. so i was actually pretty happy with the position in the end. i kind of was figuring out how to drive the car- late, yes, but with the lack of laps i've had this weekend and just performance from the car working properly, it's made my life pretty tricky”

Yes, they spent their awards night celebrating our finals exit, but it's understandable they and their fans are in a mental funk. Tribalism and rivalry momentarily aside, it's good to see them getting away from it all and working on their wellbeing. #neighbourhoodwatch

from their convo, you can literally see how close they are. haruto is always talking about jeongwoo, and they understand each other so well. i really need them to have a show like this together where they can just sit and talk about random things #하루토 #박정우
