Astronaut spots Mount Vesuvius from space | Space photo of the day for June 8, 2026
Astronaut spots Mount Vesuvius from space | Space photo of the day for June 8, 2026 "From orbit, volcanoes are some of the most beautiful natural sights." French astronaut Sophie Adenot captured the view of a lifetime in a new image of Mount Vesuvius, as seen from aboard the International Space Station. Adenot, an astronaut with the European Space Agency, is currently part of SpaceX's Crew-12 mission aboard the International Space Station (ISS) alongside NASA astronauts Jessica Meir and Jack...
Two leaks detected on International Space Station, Russian space agency says
Two leaks detected on International Space Station, Russian space agency says MOSCOW, June 5 : Russian state space agency Roscosmos said on Friday that its experts had detected two leaks aboard the International Space Station (ISS) but that there was no immediate threat to the crew. "When the transition chamber compartment of the Zvezda module was pressurised... specialists from the main operational control group for the Russian segment of the ISS detected a leak from the spacecraft,"...
Unlocking 'the true space age': Impulse Space raises $500 million to build out fleet of ultra-mobile spacecraft
Unlocking 'the true space age': Impulse Space raises $500 million to build out fleet of ultra-mobile spacecraft Impulse Space just got a lot more money to help finance its big ambitions in the final frontier. The California-based company — which was founded in 2021 by propulsion expert Tom Mueller, the first person Elon Musk ever hired at SpaceX — announced today (June 2) that it has raised $500 million in a "Series D" investment round. It will use the funds to scale up the production and...
Impulse Space raises $500 million at $4.26 billion valuation as space investing surges
Impulse Space raises $500 million at $4.26 billion valuation as space investing surges NEW YORK, June 2 : Impulse Space, a startup building spacecraft that can ferry satellites and other payloads around in orbit after launch, said on Tuesday it has raised $500 million in a Series D funding round. The funding round values the company at $4.26 billion, according to a person familiar with the matter. The company was founded by Tom Mueller, SpaceX's first employee and the propulsion engineer who...
Space-CIM: Enabling Compute-In-Memory Accelerators for Thermally-Constrained Space Platforms
Announce Type: new Abstract: The rapid growth in compute demand from artificial intelligence (AI) has driven a massive surge in data center construction, precipitating an energy and sustainability crisis. Motivated by the abundant solar energy in outer space and the recent sharp reduction in space launch costs, orbital data centers are emerging as a potential pathway for the future scaling of AI compute infrastructure. While the cold background in vacuum seems appealing for cooling,...

Higher-order spacings in the superposed spectra of random matrices with comparison to spacing ratios and application to complex systems
Announce Type: replace Abstract: Higher-order spacing statistics in the $m$ superposed spectra of circular random matrices of the same class are studied numerically. We conjecture that for given $m$ (or order $k$) and $\beta$, the sequence of modified Dyson index $\beta'(k)$ (or $\beta'(m)$) obtained using the sum of absolute differences between the cumulative distribution functions method (denoted as $D(\beta')$) is unique. Also, for a given $k$, the distribution tends to the corresponding...
Optimality-Based Control Space Reduction for Infinite-Dimensional Control Spaces
Announce Type: replace-cross Abstract: We consider linear model reduction in both the control and state variables for unconstrained linear-quadratic optimal control problems subject to time-varying parabolic PDEs. The first-order optimality condition for a state-space reduced model naturally leads to a reduced structure of the optimal control. Thus, we consider a control- and state-reduced problem that admits the same minimizer as the solely state-reduced problem.
Subspace-selective unitary manipulation based on the Hilbert-space symmetric structures in the multiple-quantum operator algebra spaces in the quantum-computing speedup theory
arXiv:2606.03859v2 Announce Type: replace-cross Abstract: The quantum-computing speedup theory considers the symmetric structures and properties of quantum systems as the fundamental Quantum-Computing-Speedup (QCS) resources which are responsible for exponentially speeding up quantum computing and simulating. At present a large and important problem is how to make use of the fundamental QCS resources to speed up essentially quantum computing and simulating. Here the author makes a great...
