NASA just demonstrated a technology that lets spacecraft communicate across multiple networks, paving the way for a more flexible and reliable space internet. NASA’s experimental Polylingual Experimental Terminal (PExT) has successfully completed its primary technology demonstration, marking an i
WASHINGTON — Quantum Space, a company led by a former NASA administrator that is developing highly maneuverable spacecraft for national security missions, will go public by merging with a special purpose acquisition company, or SPAC.
Quantum Space announced June 8 that it will merge with Inflection Point Acquisition Corp. VI, a SPAC traded on the Nasdaq exchange. The companies expect the deal to close in the fourth quarter, with Quantum Space then trading on the Nasdaq under the ticker symbol QSPC.
The deal includes a $300 million investment, known as a private investment in public equity, or PIPE, by Inflection Point into Quantum Space. The SPAC also has $253 million in trust that would go to Quantum Space, assuming none of its shareholders redeem their shares. The deal would value Quantum Space at more than $1.1 billion if there are no SPAC redemptions.

You have gone without food for days, and the temperature drops to near freezing. What do you do? For some animals, the answer is influenced by the brain’s circadian clock. Hummingbirds, bats, and mice are among the animals that can enter torpor, which reduces body temperature and metabolism. Scientists suspected that the brain’s circadian clock controls the timing of torpor, but until now the exact mechanism was not known.
Researchers at Nagoya University in Japan have identified the specific neural circuit responsible for this survival strategy. They have shown that the brain’s circadian clock, a small cluster of neurons located in the hypothalamus at the base of the brain, sends silencing signals through this circuit to a nearby temperature-regulating region, suppressing torpor during the day. The findings were published in Nature Communications.
When rockets fire into space, the insides of their engines become an extreme environment where temperatures soar and tiny particles are thrown around at hypersonic speeds. These particles behave in ways that break long-held assumptions, according to new research that could help improve the durability, safety and performance of future space and defense technologies.
The study shows that particles traveling at hypersonic speeds do not remain spherical, instead melting and deforming mid-flight in ways that change how heat, drag and energy move through rocket systems. The findings, published in Physics of Fluids, have led researchers to develop a new drag model that more accurately predicts particle behavior under extreme conditions.
The work was led by researchers from the Southeast University–Monash University Joint Research Institute, Monash University and Shanghai University.
Antimatter propulsion could be the fastest engine ever built. We explore how antimatter rockets work, their extreme energy density, and whether they could power humanity’s first true interstellar spacecraft.

NASA’s vision for a future, long-term sustained presence on the Moon gained more clarity on Tuesday as the agency announced a series of contract awards for future robotic missions.
The agency announced that two companies developing lunar terrain vehicles (LTVs), Astrolab and Lunar Outpost, would each be receiving contracts valued at about $220 million each to finish their designs and get them to the Moon’s surface.
Astrolab’s Crewed Lunar Vehicle (CLV-1) takes after its original design, called FLEX, and Lunar Outpost’s Pegasus vehicle takes heritage from its earlier Eagle design. NASA previously put out a call for LTVs that would be capable of surviving on the Moon for up to 10 years, but revised its requirements to have more readily available options to augment earlier astronaut missions.
Elon Musk just laid out one of the clearest timelines yet for artificial general intelligence. According to Musk, AGI could arrive as early as next year, with digital superintelligence potentially surpassing the collective intelligence of humanity by 2029 or 2030. → Try Visionary Society for $1 — https://bit.ly/VSONE

In this full breakdown, we analyze Musk’s probability estimates on existential risk, why he believes abundance is the most likely outcome, and how exponential AI compute growth is accelerating faster than any technology in history.
From Neuralink’s first human telepathy implant to the possibility of brain-state backup, from Nvidia’s AI chip dominance to Starship’s full reusability unlocking a multiplanetary civilization, Musk connects AI, brain-computer interfaces, and space into one long-term strategy. This video explains the compute explosion, the power bottlenecks, the singularity timeline, and what it really means when digital intelligence begins to outscale biological intelligence.

NASA’s new electric propulsion engine set a U.S. power record and could transform future Mars missions. The thrusters use much less fuel than chemical rockets while gradually reaching extremely high speeds.
