"Satellite operators are in panic mode due to a worsening launch crisis" by @arstechnica / @sciguyspace - #SpaceX has been making noises of phasing out #Falcon9 rockets when #Starship is ready. Concern is growing in the #space industry that it would pull the rug out from under many smaller satellite customers where competing launchers (#RocketLab #Neutron, #ULA #Vulcan, #BlueOrigin #NewGlenn, etc) aren't yet ready to fill the gap. https://arstechnica.com/space/2026/08/theres-a-huge-launch-crunch-right-now-and-it-will-probably-get-worse/ #NewSpace #business #economy

"Policy experts: Europe stuck between “rock and a hard place” on launch" by @arstechnica / @sciguyspace - #Business analysts put numbers to what any #spacegeek could have told them: #Europe🇪🇺 has fallen behind on #space launch because it hasn't significantly reduced its cost of launch to orbit. All new commercial rocket🚀 projects are at least partly reusable. #ESA's vertical takeoff/vertical landing VTVL experiment hasn't flown yet. Time to prioritize.🤔 https://arstechnica.com/space/2026/08/policy-experts-europe-stuck-between-rock-and-a-hard-place-on-launch/ #NewSpace #economy

"Blue Origin narrowing in on root cause of catastrophic rocket accident" by @arstechnica / @sciguyspace - #BlueOrigin has identified the part which failed in the May explosion of a #NewGlenn rocket during a hot-fire engine test. It was a liquid oxygen valve on a BE-4 engine. However, they don't yet know how that part failed, and therefore the root cause of the explosion. Investigation continues. Once identified, existing engines can be fixed. https://arstechnica.com/space/2026/08/blue-origin-narrowing-in-on-root-cause-of-catastrophic-rocket-accident/ #NewSpace #space #business

Сборщик мусора в Dart. Часть 2: поколения и scavenge
В первой части мы разобрались как Dart отличает число от объекта. Эти знания нам пригодятся, чтобы разобраться в дальнейших хитростях сборщика. Перед нами стоит самый главный вопрос: А как сборщик все-таки за собой убирает? Молодое и старое поколение. Что происходит в обычном build() у Flutter-виджета? За один кадр создается куча временных объектов: EdgeInsets, Padding, промежуточные TextStyle, какие-то списки, замыкания. Живут они до следующего ребилда(Не учитывая const). Также у нас есть и другая категория объектов, которые живут долго: синглтоны, кэши, репозитории, состояние приложения. Они создаются один раз и живут все время работы. Отсюда вывод, если молодые объекты пересоздаются пачками, а старые в основном живут, то убирать их одинаково не выгодно. Именно поэтому Dart делит кучу на 2 поколения...

"Space Force Picks Rocket Lab for Suborbital Launches from Alaska" by Air & Space Forces Magazine - Kodiak, Alaska will be a new launch site for Rocket Lab. RL already does uncrewed commercial launches (suborbital and orbital) from their private launch site in Mahia, New Zealand and from the US federal range at NASA Wallops, Virginia, USA. Pacific Spaceport at Kodiak Island is the State of Alaska's launch range. https://www.airandspaceforces.com/space-force-rocket-lab-suborbital-launches-alaska-spaceport/ #military #NewSpace #space #business

"German aerospace company signs 10-year deal to use N.S. space launch pad" by CBC🇨🇦 - Isar Aerospace plans to begin commercial orbital launches of small to medium satellites from Nova Scotia on Canada's Atlantic coast in 2028. (Europe doesn't have sites to launch east over water without population downrange.) https://www.cbc.ca/news/canada/nova-scotia/german-aerospace-company-signs-10-year-deal-to-use-n-s-space-launch-pad-9.7261257 #NewSpace #Canada #business

Isar Aerospace had to abort the launch of the Spectrum 2 rocket once again. A new launch attempt could be on the horizon in July 2026.

"With Starfall, SpaceX eyes an edge in global cargo delivery from orbit" by @arstechnica / Stephen Clark - #SpaceX #Falcon9 launch today had a surprise experimental payload called "Starfall", announced just before launch to be a re-entry pod for #cargo delivery on suborbital flight or re-entry from orbit, landing by parachute wherever a probably-military cargo needs to go. Most details so far are from a public environmental statement for FAA. https://arstechnica.com/space/2026/06/with-starfall-spacex-eyes-an-edge-in-global-cargo-delivery-from-orbit/ #NewSpace #space #business

As space startups prepare to launch the first commercial AI data centers into Low Earth Orbit, the final frontier isn't engineering; it's risk management. Discussions are officially underway with global insurers to create a brand-new asset class for orbital silicon.

This article does a good job covering my concerns with space based data centers:
https://spectrum.ieee.org/orbital-data-centers-heat
Thermodynamics is a huge problem, losing two of three ways to shed heat is a real challenge. Adding a large per pound fixed cost to each component is show stopper I would think. Their calculation assumes $44/kg when the current rate is really like $5000/kg.

I knew the UP Aerospace team because it started as a commercial development of the Civilian Space eXploration Team CSXT amateur rocket. When the CSXT Space Shot 2004 became the first successful amateur rocket to space (after many attempts), I led the Stratofox tracking team that recovered the rocket from deep in the mountains of Nevada's Black Rock desert. When Jerry started UP Aerospace, it gave us all a hint he likes borrowing acronyms from railroads. 😀 #NewSpace #rocketry #space #business
