A lot has been said about how Kitten Space Agency and Kerbal Space Program are similar. But it has become clear that there are a couple of major differences. Today, we're highlighting six of them:

Amid an increasingly uncertain geo-economic climate, Japan's trade ministry is looking to expand the scope of its economic security policy to cover new areas including undersea cables and satellites. https://www.japantimes.co.jp/business/2025/04/16/economy/economic-security-plan/?utm_medium=Social&utm_source=mastodon #business #economy #economicsecurity #underseacables #satellites #rockets #meti #us #china

There are only 2 "#spaceport" 
so far in #OpenStreetMap which pretended to be one unless they never launched something to #space 
(for a considerable amount of time) : #SpaceportAmerica and #CornRanch (#BlueOrigin's #NewShepard launch site) https://taginfo.openstreetmap.org/keys/aeroway%3Asuborbital#values. #SpaceportCornwall 
has never been one (other than for propaganda) https://www.openstreetmap.org/way/1105816254

During my childhood in 1969, we were inspired to build little cardboard #rockets to fly to the moon. Our protoype's flight lasted only the length of one jump. We would never have thought of spending all our pocket money on it, celebrating these seconds as a success, or polluting the environment under the applause of Bavarian politicians.
After a false start, we had to clean up every last shred and realised that we had screwed up. Afterwards, we preferred to watch ants on Earth.
A German test rocket aimed at kickstarting satellite launches from Europe fell to the ground and exploded 40 seconds after takeoff from a Norwegian space port on Sunday. https://www.japantimes.co.jp/news/2025/03/30/world/science-health/german-test-rocket-failure/?utm_medium=Social&utm_source=mastodon #worldnews #sciencehealth #isaraerospace #germany #norway #space #nasa #rockets #space

Been out this morning delivering some training on laser cutter maintenance and optimisation, just back to a couple of ACE items in the post. My hard copy of the Half Cat rocketry book and, amongst some components for work a pair of engineer brand pliers for my growing collection! Nice. #rockets #tools #opensource
NASA astronauts Butch Wilmore and Suni Williams returned to Earth Tuesday, nine months after what was supposed be a weeklong stay on the International Space Station. https://www.japantimes.co.jp/news/2025/03/19/world/nasa-astronauts-return-earth/?utm_medium=Social&utm_source=mastodon #worldnews #nasa #astronauts #space #spacex #rockets

A pair of U.S. astronauts stuck for more than nine months on the International Space Station will be returned to Earth on Tuesday evening, NASA said. https://www.japantimes.co.jp/news/2025/03/17/world/science-health/stranded-us-astronauts-nasa/?utm_medium=Social&utm_source=mastodon #worldnews #sciencehealth #nasa #spacex #rockets #space #astronauts

All set for an evening talking #rockets and rocket design using #opensource tools :) My kinda workshop!

Couple of years ago I remember someone asking why does Europe continue with the Ariane program, why not save the money and buy launches from spaceX or Soyuz.
Well. Looking at the political landscape. I think the question should now be, why is Europe so behind with low cost space launch capability?
If there's a #war between #Europe and #US - #Russia, we need satellite imagery to assist. All European #rockets currently fly out of #FrenchGuiana, which is easy to take over by the #USNavy.
A more sensible approach is to design (or license before it's too late) something like RocketLab's Electron (320 kg to LEO, 200 kg to SSO, very cheap). We don't need anything more powerful. Then launch it from the southern tip of #Crete.
The Starlink communications network is facing stiff challenges to its dominance of high-speed satellite internet, including from a Chinese state-backed rival and another service financed by Amazon.com founder Jeff Bezos. https://www.japantimes.co.jp/business/2025/02/24/tech/musk-starlink-china-satellite-internet/?utm_medium=Social&utm_source=mastodon #business #tech #elonmusk #starlink #satellites #jeffbezos #amazoncom #china #telecoms #internet #tech #rockets #spacesail

The proof of concept shows that at the current achievable flow rates of #CO2 and water, it is possible to meet #NASA’s 16-month deadline for refueling #rockets on #Mars 
. It can be scaled further to meet tighter rocket refueling 
deadlines. The use of Martian nighttime temperatures for heat 
exchange can potentially reduce the dependence on power-hungry cryogenic methods for gas liquefaction. https://pmc.ncbi.nlm.nih.gov/articles/PMC9118664
