SpaceX email to Canadian regulators maps out some of Starlink's plans for "next-generation" direct-to-device (direct-to-cell) satellites/service.

SpaceX indicates it will begin launching its next-generation spacecraft in "late 2027" and by the end of 2028 will have "thousands more satellites" in space.

Success depends on a BIG caveat - consumers will need to purchase next-gen mobile devices! https://www.pcmag.com/news/starlink-mobile-will-span-thousands-of-satellites-by-2028

Coming Soon! TheTechAptitude newsletter https://techaptitude.substack.com/ is planning to post a detailed overview of Starlink satellite broadband service - stay tuned! #Space #SpaceX #Starlink #SatelliteBroadband #Internet #SpaceInternet #Direct2Device #Direct2Cell #TechAptitude #Mobility #MobilePhones #Satellites

Quantum Qubits are highly susceptible to errors leading to decoherence. Errors can be caused by an assortment of factors such as thermal and electromagnetic fluctuations, and material defects.

So, what can be done about this fragility? We apply Error Correction - of course!

Quantum error correction (QEC) is a crucial capability in any Quantum system - learn more in this TechAptitude post!

Fungible Tokens for All!

Here is the story and working details behind the Ethereum ERC-20 token standard. Ethereum quickly gained a strong reputation for hosting many/most of the largest crypto tokens including USDC, USDT, and BUSD and this success is due in large part to the establishment of the ERC-20 standard.

In this TechAptitude post we dive into how ERC–20 tokens work and the ever growing scope of use cases supported.

DoD has spent ~ $1.8B for ~ 10,000 Army AR combat goggles that will now sit in on the shelf.

The goggles produce headaches, nausea, and more than 80% of soldiers reported physical symptoms within three hours of wearing the device.

MOST IMPORTANTLY, soldiers wearing the devices had worse battlefield performance than the equipment it was meant to replace.

Microsoft x'ferrd this canard to Anduril in April 2025, and Anduril is attempting to re-engineer this mess. Good Luck with that Palmer! https://www.techtimes.com/articles/320165/20260711/army-ar-goggles-gao-confirms-18b-spent-headsets-too-sick-field.htm

Quantum Key Distribution (QKD) is, if not the most active area in Quantum, it's darn close to it. Why?

Quantum Key Distribution (QKD) enables two parties to produce a shared random and completely unbreakable secret key known only to them, which can then be used to secure communications by encrypting and decrypting messages.

This area of the Quantum ecosystem will very likely be the first to be commercialized on a broad scale.

NASA earth observation satellites have been shown to be able to locate the approximate positions of GPS jammers - typically within 3-6kms.

Researchers looked at data from the Cyclone Global Navigation Satellite System (CYGNSS) and NASA-ISRO Synthetic Aperture Radar (NISAR), satellites to locate known GPS jammer sites (in Iran) and indicate how this information has potential usefulness for supporting the creation and distribution of warnings for aviation and maritime navigation that may be affected by GPS jammers. https://arstechnica.com/gadgets/2026/05/nasa-satellites-can-spot-gps-jammers-on-earth/

Well, it’s good that someone is drawing a line in the Crypto sand.

Google accelerates its readiness timeline to prepare for “Q-day” with post-quantum cryptography (PQC) migration to 2029. Reminder: Q-day = the date when quantum computing becomes operational and is powerful enough to break the digital signatures that secure the Internet, crypto (blockchain + Ethereum), and just about every other Information system in use today.

The Bitcoin crypto network relies on ECDSA elliptic curve signatures. https://techaptitude.substack.com/p/ecdsa-cryptographys-role-in-securing With an exposed crypto signature public key, a quantum computer could derive the private key. And then, the crypto assets would be freely available to a hacker.

Android 17 will integrate ML-DSA, an algorithm standardized by the NIST to secure digital signatures. https://security.googleblog.com/2026/03/post-quantum-cryptography-in-android.html

Someone at META FINALLY has seen the light in the VR tunnel and it is a dead train.

Meta recently announced starting on June 15, 2026, it will no longer be possible to build, publish or update VR worlds, and Horizon Worlds will not be accessible with VR headsets - the spaces will continue to be be available via the Horizon mobile app only.

This comes just a few weeks after Meta cut over 1,000 employees from Reality Labs, the unit responsible for the metaverse. https://www.cnbc.com/2026/03/18/meta-horizon-worlds-metaverse-vr.html

In 2018, I first wrote about how dedicated "VR Worlds" would be a #Fail and would be destined to be highly niche products and NOT be the world changing tech as claimed by proponents.

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/
