Will SpaceX still be a launch company after its historic IPO?
Will SpaceX still be a launch company after its historic IPO? The company is now "a conglomerate with exposure to AI, advertising, communications and space manufacturing and operations." On May 20, SpaceX filed with the U.S. Securities and Exchange Commission (SEC) key documentation for an initial public offering (IPO) of stock.
NASA just proved spacecraft can switch between multiple satellite networks
NASA just proved spacecraft can switch between multiple satellite networks - Date: - June 6, 2026 - Source: - NASA - Summary: - NASA’s PExT terminal has shown that spacecraft can seamlessly communicate through multiple government and commercial networks, a major step beyond traditional single-network systems.
Design Space Exploration of DMA based Finer-Grain Compute Communication Overlap
arXiv:2512.10236v2 Announce Type: replace Abstract: Modern ML workloads demand distributing training and inference across multiple GPUs. However, these parallelization techniques often suffer from exposed critical-path communication, leaving a potential 1.7x speedup on the table through compute-communication overlap. Prior overlapping methods harness the fact that ML model state and inputs are already sharded into the number of GPUs, and overlap the compute and communication at shard...

Construction of cyclic codes with large minimum distance from power functions over odd characteristic finite fields
Announce Type: new Abstract: Cyclic codes with dimensions exceeding half of the code length and minimum distance greater than the square root of the code length are of significant interest due to their high transmission efficiency and strong error-correcting capability. Such codes are well suited for demanding applications, including communication and storage systems, post-quantum cryptography, radar and sonar systems, wireless sensor networks, and space communications. Motivated by the work...
GHz-bandwidth InAs/InAsSbP barrier infrared detectors for the 3.0-3.7 {\mu}m spectral region operating at room temperature
arXiv:2605.26276v2 Announce Type: replace Abstract: The demand for fast mid-wave infrared photodetectors is fueled by high-rate free-space optical communication and optical frequency comb spectroscopy. To date, only a few multi-GHz photodetectors have shown sensitive room-temperature operation in the 3.0-3.7 {\mu}m band, yet their commercial availability remains scarce. In this work, we present the remarkable response speed of an InAs/InAsSbP nBp barrier detector - a type typically not...
Efficient Numerical Modeling of Near-Field Diffraction in ORIS-Assisted Free-Space Optical Links
Announce Type: new Abstract: This paper investigates near-field propagation in optical reconfigurable intelligent surface (ORIS)-assisted free-space optical (FSO) communication systems. Unlike conventional far-field scenarios, near-field propagation involves complex diffraction effects that hinder tractable closed-form analysis. To address this issue, a numerical framework for evaluating the optical field distribution of ORIS-assisted FSO links is proposed.
How SpaceX President Gwynne Shotwell has achieved Musk's lofty ambitions
How SpaceX President Gwynne Shotwell has achieved Musk's lofty ambitions June 8 : When SpaceX goes public on Friday with what is expected to be a record-setting IPO, it will cap two decades of founder and CEO Elon Musk's ambition to transform rocketry, satellite communications and humanity’s reach into space. Each step of the way, there has been a guiding hand largely out of view: the company's president, Gwynne Shotwell, who has spent 24 years focused on building and selling SpaceX through...
SpaceX lands a $4 billion contract to help build Trump's Golden Dome
SpaceX lands a $4 billion contract to help build Trump's Golden Dome That’s on top of another $2 billion contract awarded to SpaceX earlier this week. Elon Musk's conglomerate company for space exploration, artificial intelligence and telecommunications can now add military defense to its mission statement. SpaceX was awarded a $4.16 billion contract from the Space Force to build satellites that track foreign aircraft and missiles as part of President Trump's proposed Golden Dome project.
General Convex Agreement with Near-Optimal Communication
arXiv:2602.21411v2 Announce Type: replace Abstract: Byzantine Agreement (BA) considers a setting of $n$ parties out of which up to $t$ can be byzantine (malicious), and requires the honest parties to agree on an input subject to a condition called \emph{validity}: if all honest parties have input $v$, the output agreed upon must be $v$. Convex Agreement (CA) strengthens BA by requiring the output agreed upon to lie in the convex hull of the honest parties' inputs. This validity condition...
