Ground station setup: tweaking RF and control cables routing to achieve full 0-360° azimuth and 0-180° elevation of antenna coverage for aqusition as many data from the orbit over each pass as possible. If you've ever tried this, you know it's pretty tough. Happy tracking! 📡

Venus detected at 47 GHz 🪐📡
1.8 m dish + LibreSDR/Maia SDR wideband radiometer: +3.45 ± 0.20 mdB (17σ) over three days, null test 1.5° away gives zero.

I can confirm that Cosmos-2612 is tailing ICEYE-X36 like a cat after a mouse - though this cat ought to realize that an even larger predator is likely keeping an eye on it 👀
Intercepted military HF communication on 5135 kHz (USB). The best detail? At ~1:02, you can hear a staff telephone ringing in the background ☎️ This is proof of a "hot mic" – the order is being read live by an operator from a command center, not a speech synthesizer.
It's a pleasure to listen to an HF radio station while working on your computer, using modern tools like LLM, the cloud, etc., something that was unthinkable when such stations were the only means of live and long-distance communication. Now with radio enclosed in a matchbox!

NISAR enters Science Phase 🇮🇳🇺🇸
NISAR (~2400kg) was launched on 30 July 2025, onboard GSLV to a 747km (circular) Sun synchronous Orbit 🚀
The unfolding of the 9m boom and the deployment of the 12m diameter antenna reflector, took 6 days (9 Aug 2025 to 15 Aug 2025).
On 19 Aug 2025, for the first time the S-band SAR (ISRO) captured the fertile Godavari River Delta in Andhra Pradesh, Since then it has been regularly imaging the Indian Landmass and Global Calibration-Validation sites in various payload operating configurations.

A bit of RF teardown for SDR geeks. Two original Ettus USRP1 with four extensions cards which each can operate from 0.8-2.3 GHz.
Nice set of antennas! Anyone know and share details?
York Space Systems has finally delivered the first batch of satellites for the SDA's Tranche 1 Transport Layer! Launch is set for NET Sep. 10. Each batch comprises of 21 satellites, with York, Lockheed Martin, and Northrop Grumman each delivering 2 batches businesswire.com/news/home/2…

Here's a view from the Viking 1 lander on the Chryse Plains of Mars in 1976, and a view OF the lander taken from space by Mars Reconnaissance Orbiter, which is studying Mars today.

ALT A desert plain with sand and dark rocks and boulders under an orange sky with thin wisps of clouds. In the foreground, part of the Viking 1 lander can be seen, with red stripes that are part of a US flag emblem.

Paving the way for America's future on Mars!
50 years ago today, NASA's pioneering Viking 1 mission took flight! The world's first successful lander on the surface of Mars, made unprecedented observations and contributing significantly to our understandings of the Red Planet.
ALT Viking 1, at the tip of a massive Titan/Centaur rocket, rises into the sky from Complex 41 at Cape Canaveral Air Force Station at 5:22 p.m. EDT, August 20, 1975. Palm trees are silhouetted in the foreground, and a plume of dark exhaust darkens the right-hand side of the frame.
