Y Combinator’s Post

Milestone alert 👍! Last week we tested the #CFRP demonstrator of a landing leg for a reusable rocket 🚀. The landing leg together with a telescopic system and an integrated locking mechanism will guarantee a stable landing and the reusability of the rocket. The test campaign began with small drop distances and the alignment of countless measuring points. Finally, we brought the demonstrator into an upright position for the final deployment test - just like a realistic rocket landing. Then the 7-meter-high landing leg withstood all the impact energy 💥 by deploying vertically under gravity and deployed properly. The low weight and high performance in terms of strength, are groundbreaking for the future technology of European rockets, where #sustainability will be the focus. But now it's time to evaluate all the test data before moving on. The demonstrator is part of the EU #HorizonEurope program SALTO. #rocketscience #greenspace #composites #leightweight #spaceEnablers

Rocket Lab is going to the moon as it supports Firefly Aerospace's Blue Ghost Mission 1. The company supplied high-efficiency photovoltaic assemblies, delivering 400 watts of power over 1,470 operational hours, and supporting the mission's cruise and landing phases. Separately, BlackSky Technology has delivered its first Gen-3 satellite to Rocket Lab for a February launch in New Zealand, offering 35-centimeter high-resolution imagery and AI-enabled analytics. #RKLB #BKSY #Firefly #RKLBStock #RKLBNews #RKLBStockNews #BKSY #BKSYStock #BKSYNews #BKSYStockNews #RocketLab #RocketLabStock #RocketLabNews #RocketLabStockNews #BlackSky #BlackSkyStock #BlackSkyNews #BlackSkyStockNews #Firefly #FireflyStock #FireflyNews #FireflyNews #FireflyAerospace #BlueGhostMission1 $RKLB $BKSY

So much cleaner and simpler to assemble and refurbish. More thrust as well.

no part is the best part

Those 'lights' on the outer-hull of the #CTPcraft are NOT 'lights'. Those 'lights' are part of the CEMAS™ Arrays which are part of the craft's CTP Gravitic Propulsion Systems. #UFOs/#UAPs #UFOtruth #Disclosure #CTPisDisclosure #tech #space #spaceindustry #spacetravel #spacetech #newspace #newspacetech #CTPSpace

It all begin with a small step

NO, it's not a White Elephant wrapped gift, it's a rocket. The story unfolded during Rocket Lab's annual rocket challenge where we get together in groups of IT, Avionics, Space System, Engineering, Security etc. folks to make a model rocket with supplies like cardboard box, gift wrapper, bamboo skewers, glue sticks/gun, scissors and one single rocket fuel cartridge in ~3 hours. The rocket with longest ground flight length wins. We called our the "Pie Rocket" (slight deviation from the Star Wars spaceship design that we started with 😃) supported on two sledges. It worked but we did not win. This is one of the best experiences at Rocket Lab where everybody gets to contribute to a mission - no idea is small idea, literally. #annualrocketchallenge24

One cool concept that doesn't fully meet the eye here is the idea of "induced mass", meaning the component mass on the Starship/Super Heavy vehicles required to support Raptor operations. Not only is v3 a massive streamline of the engine, but it incorporates startup, cooling, and fire/heat mitigation features that simplify other Starship systems and thereby cut "induced mass". A truly impressive score for the Starship program that translates directly to higher payload capability!

The most robust, efficient and optimized full flow staged combustion cycle Methane-Oxygen mixture running engine produced to date. Starship is quite literally the biggest object to ever even take off the ground, let alone being the biggest object to reach orbit and beyond, intending to be the first ever vehicle to transport humanity to the moon, Mars and eventually into interstellar space, even tolerating the heat of re-entry. After landing, not even landing back but being autonomously caught by a pair of giant steel robotic autonomous chopstick-like rods on the biggest launch tower to have ever been created.

Stoke Space Scores a Success In First Test Firing of Engine For Reusable Nova Booster: Kent, Wash.-based Stoke Space successfully completed the first hot-fire test of its reusable Nova launch vehicle's first-stage engine, which reached 350,000 hp in under a second during a two-second test on June 5. GeekWire reports: During the two-second test, the engine ramped up to its target starting power level, producing the equivalent of 350,000 hp in less than a second, and held that power level until shutdown. At full power, the full-flow staged combustion engine is designed to produce over 100,000 pounds of thrust. The rocket engine was designed and manufactured in just 18 months. The medium-lift Nova rocket's first-stage booster will be powered by seven of the engines. Stoke successfully conducted a vertical-takeoff-and-landing test flight of its reusable second stage last September. Since then, the company has been focusing on first-stage development. For the rest of this year, Stoke expects to continue maturing its engine and vehicle design while scaling operations for orbital launch. Stoke Space said last year that it was targeting 2025 for its first orbital test flight -- but that timetable depends on progress in the development program. Read more of this story at Slashdot.
