A team of scientists from the SETI Institute, University of California Davis and the Alaska Whale Foundation, had a close encounter with a non-human (aquatic) intelligence. The Whale-SETI team has been studying humpback whale communication systems in an effort to develop intelligence filters for the search for extraterrestrial intelligence. In response to a recorded humpback…

As frustrating as the Fort Knox-esque canister conundrum has been, what has been analyzed so far has offered some pretty incredible results — though they too have left scientists with more questions than answers. … Those lighter-colored bits are magnesium, phosphate, and sodium per the early analysis, and that bright and brittle outer layer chips off to…

The uncrewed New Shepard 24 test flight will refly the science payloads that were aboard the New Shepard 23 flight, which experienced an engine nozzle failure at 1 minute and 4 seconds following liftoff in September 2022. The capsule’s emergency escape system performed as intended, rapidly pulling the spacecraft away from the disintegrating rocket and…

NASA’s Voyager 1 probe has been cruising into distant space for 46 years old — and some of that advancd age is apparently showing. As NASA explained in a blog update, one of the pioneering probe’s computers, known as its flight data system (FDS), is “not communicating properly.” Because of these translation issues, the craft launched during…

It’s tempting to invoke Berger’s Law, the guideline championed by my Ars colleague which states that if a launch is scheduled for the fourth quarter of a calendar year—and if it is at least six months away—the launch will delay into the next year. Given Blue Origin’s history of New Glenn delays, that’s probably the…

I was today years old… As best I can determine, Barrow first floated the scale in his 1998 book Impossibility: The limits of science and the science of limits (Oxford University Press). Inverting Kardashev, Barrow was interested in a civilization’s ability to control smaller and smaller things, relying on the observed fact that as we have explored…

The exact altitude the X-37B will be flying through is unclear, but hobbyists and amateur sleuths who use open source information to reconstruct trajectories of top-secret military spacecraft suggest the Falcon Heavy will haul the winged vehicle into an orbit that could stretch tens of thousands of miles above the planet. What’s more, the Falcon…

New Horizons is now nearly twice as far from the Sun as Pluto, the outer planets are receding fast, and interstellar space is illuminated by the vast swath of the Milky Way ahead. But the spacecraft’s research is far from over. Its instruments are all functioning and responsive, and the New Horizons team has been…

Welcome to Edition 6.22 of the Rocket Report! We’re nearing the end of 2023, and it’s been an incredible year for rocket debuts. Early in the year we saw small lift vehicles from Relativity Space and ABL, and in the spring Japan’s H3 and SpaceX’s Starship rocket. There’s one big one left: United Launch Alliance’s…
