Sending a rocket into space typically requires about 90% of the rocket’s initial weight to be fuel. This limitation could be overcome by wirelessly transmitting the needed power to the rocket through a beam of microwave radiation. A research team from Japan has investigated the viability of using such microwave-powered propulsion for real-world applications. In …
The latest UN IPCC, climate change report is out. the IPCC report says that global surface temperature will continue to increase until at least the mid-century under all emissions scenarios considered. If we are going to fix the world’s climate then it matters how much things cost, the scale of the problem and scale of …
Intel was the dominant semiconductor chip maker for decades. They were a generation or two ahead of all competitors. However, six years ago Intel started badly missing deadlines for new chips. Intel fell behind TSMC and AMD. Intel has new plans and new technologies that they hope will let them catch up and then pull …
Rapidly iterating on versions rockets and rocket engines is a huge advantage for SpaceX. Elon said he expects that the fifth version of the Raptor engine should be an A+ version of that engine.

This is the first time we are seeing the orbital Starship with heatshield on the launch pad. This is the first time we are seeing the Starship stacked onto the Super Heavy booster. In 2022, this could be a weekly sight with new or reused boosters and Starships. In 2023 and beyond, this could be …
In 2014, Blue Origin said the BE-4 engine would be ready by 2017 but it is likely slipping to 2022. ULA need BE-4 for its new Vulcan rocket and Blue Origin needs it for the New Glenn rocket. Blue Origin did not have enough components to build development engines, and this has led to long …
Last Thursday, the Russian Multipurpose Laboratory Module (MLM) called Nauka had unplanned firing of MLM thrusters that caused the station to move out of orientation. NASA ground teams regained attitude control and the motion of the space station is stable. The crew was never and is not in any danger, and flight controllers in Mission …
Elon Musk gave a tour of the Starbase Factory to the Everyday Astronaut. He says that manufacturing systems are much harder than designing rockets. He says the launch tower and launch facilities are far more challenging than the rockets. Highlights: The hard part about the Raptor engine is how do we make it for less …
