Testing satellite communications in a lab can only get you so far. Validating in orbit is critical for testing how space communications actually work when you're dealing with real interference, weather disruptions, and navigating a crowded spectrum. Adam Wexler on why testing operations in space is crucial.

Dream Chaser hitched a ride with a Freightliner Trucks Cascadia truck down one of the world's largest runways at NASA's Kennedy Space Center! Our spacecraft endured high-speed testing on the same landing strip where Space Shuttles once touched down. The team also successfully tested communications with Mission Control in Louisville, Colorado using NASA's satellite network. Testing wrapped up with a full post-landing recovery rehearsal - another crucial milestone completed on our journey to space! YouTube:

Terran R testing is in full swing. 🔁 At Stennis Space Center , our final development engines are running gimbaled hot fires with flight-like IPS. 🔁 The historic A2 test stand retrofit is underway—major fluids equipment has arrived on-site. 🔁 In Long Beach, early load tests are validating structural models, and our latest structural test stand is nearly ready for full-scale ops. 🔁 Avionics reached orbit with hardware-out-of-the-loop testing with a full-scale vehicle box count—hardware-in-the-loop is next. Catch up on the latest from the Terran R program:

☀️A new era in space weather forecasting is beginning... Last year, we saw an increase in solar storms that lit up the skies with stunning auroras across Europe. However, these events can be disruptive, effecting power, satellites & communications. Space weather needs to be predicted early and accurately to give us the crucial time needed to protect satellites, astronauts and vital infrastructure on Earth. That’s where our Vigil mission comes in. Acting as a dedicated ‘space weather reporter’, Vigil will drastically improve our forecasting abilities with its specialised set of instruments. 🔗

Climate modification nanoparticles in our atmosphere are engineered, lab testing confirms. Climate engineering jet aircraft dispersions are not "jet exhaust / soot", they are manufactured nanoparticles of elements specifically named in climate engineering patents. Geoengineering Watch has done extensive environmental testing over many years at the surface and at altitude. Atmospheric testing was carried out with a NOAA flying lab and a private jet testing platform, climate engineering elements were present in samples taken. Global geoengineering operations aren't just a dangerous proposal, they are an ongoing reality. Follow us for the latest news on geoengineering.

Endeavoring for not just one, but TWO Moon landings in 2028. Coming weeks: Artemis II around the Moon Mid-2027: Artemis III rendezvousing with one or both HLS providers, testing space suits in low Earth orbit Early 2028: Artemis IV lunar landing Late 2028: Artemis V lunar landing, beginning work on lunar base This is how we get back to the Moon with urgency, to stay.

$RKLB Rocket Lab CEO Sir Peter Beck explains why the acquisition of Iridium is so crucial: "If you want to do large scale communications globally, you must have spectrum. And for us, this deal really enables us to accelerate our entry into this market." "And the reason why the Iridium spectrum is incredibly important to us is that it is global and it is L-band. And L-band is important because if you want to do safety critical comms, you need that band to penetrate through weather and harsh conditions. It is a band that ensures that you can always be connected."

"The most important thing in the next 3-4 years is data centers in space. In every way, data centers in space, from a first principles perspective, are superior to data centers on earth. In space, you can keep a satellite in the sun 24 hours a day. The sun is 30% more intense, which results in six times more irradiance than on Earth. So you don't need a battery. The cooling in these data centers is incredibly complicated. Space cooling is free. You just put a radiator on the dark side of the satellite. The only thing faster than a laser going through a fiber optic cable is a laser going through absolute vacuum. Link satellites with lasers, and you have a faster and more coherent network than any data center on Earth."
