Weekend reading with TechAptitude!

Quantum networks hold the potential to enable fundamentally new capabilities, including ultra-secure communication with unbreakable encryption, distributed quantum computing, and hold out the promise of creating a “Quantum Internet”. Check it out!

Space Development Agency (SDA) cops to issues with scaling its Proliferated Warfighter Space Architecture (PWSA). The agency is grappling with a 2-3 month schedule slip. Core issues include:

Satellite Contact Failures: SDA and its vendors have struggled with the on-orbit checkout process – aka an inability to establish contact with one of its satellites launched in late 2025.

Component Scarcity: Sustained shortages of optical communications terminals (OCTs) and encryption devices continue to serve as the “critical path” for all vendors.

Launch Schedule Pressure: The next scheduled mission, T1TL-A, is ~ 4 months behind schedule due to the 45-day government shutdown, a launch rocket tech glitz, and issues with onboard software for satellites. https://satnews.com/2026/03/08/space-development-agency-faces-growing-pains-as-pwsa-scaling-hits-chokepoints/

Laser’s in Space!

The U.S. Space Development Agency (SDA) is building the next generation optical/laser based mesh network across hundreds of satellites in low earth orbit to provide highly secure low-latency communications and missile defense.

SpaceX opens the door to "sharing" its spacecraft tracking data with its "StarGaze" Space Situational Awareness (SSA) system.

Stargaze aggregates data from ~ 30,000 star trackers distributed across the StarLink satellite fleet to generate accurate orbit estimates and predictions of position and velocity for all detected objects in near real-time and the system generates Conjunction Data Messages (CDMs). 

SpaceX will make Stargaze conjunction data available to any satellite operator (free of charge) that submits its own ephemeris (trajectory) data to the platform. Stargaze ephemeris is updated and shared publicly every hour.

BIG question: How long will Stargaze be "free of charge" ??? https://news.satnews.com/2026/02/18/spacex-unveils-stargaze-system-to-revolutionize-space-traffic-management/

Exploring the world of the artist known as ECDSA!

In the latest TechAptitude post we dive into the primary cryptographic algorithm used in many blockchain based systems including Bitcoin and Ethereum, Binance Smart Chain, and Avalanche - Elliptic Curve Digital Signature Algorithm (ECDSA).

We review ECDSA and how it secures cryptocurrencies like BitCoin and Ethereum.

It is a matter of time before Quantum Computing gains the ability to crack today’s core public key encryption methods.

Our latest post on TechAptitude outlines the efforts by NIST to generate new cryptography standards to help withstand future quantum powered cyber attacks. Check it out!
