The recent SpaceX Raptor engine was actually a real breakthrough. It was a holy grail desired by NASA and the Soviet Union. The Soviet Union almost had it, but when we landed on the Moon they stopped development. The engine is a “full-flow staged combustion” engine.
“Full-flow staged combustion (FFSC) is a twin-shaft staged combustion cycle that uses both oxidizer-rich and fuel-rich preburners. The cycle allows full flow of both propellants through the turbines; hence the name The fuel turbopump is driven by the fuel-rich preburner, and the oxidizer turbopump is driven by the oxidizer-rich preburner”
Followers of the Church of Elon will no doubt already be aware of SpaceX’s latest technical triumph: the test firing of the first full-scale Raptor engine. Of course, it was hardly a secret. As he often does, Elon has been “leaking” behind the scenes information, pictures, and even video of the event on his Twitter account. Combined with the relative transparency of SpaceX to begin with, this gives us an exceptionally clear look at how literal rocket science is performed at the Hawthorne, California based company.

Five-thousand tons of water-ice delivered to cislunar space per two-year mission! In a recent announcement, TransAstra Corporation proposed a spacecraft able to achieve this. They call it the Queen Bee, a new part of the Asteroid Provided In-Situ Supplies (APIS; Apis) architecture. Queen Bee is a large scale version of their asteroid mining spacecraft design.
TransAstra is a Los Angeles, California based aerospace company founded in 2015 by Joel Sercel. Their goal is to help make industrial processes in space possible. A key process they study is extracting volatiles, including water, from small Near Earth Asteroids (NEA). Their past work has focused on Optical Mining, asteroid encapsulation, and solar thermal thrusters for the mining and utilization of carbonaceous Near Earth Asteroid (NEA) volatiles.
Turns out it is smarter than we think.
It is well known that the circuits in this part of our nervous system, which travel down the length of our spine, control seemingly simple things like the pain reflex in humans, and some motor control functions in animals.
Now, new research from Western University has shown that the spinal cord is also able to process and control more complex functions, like the positioning of your hand in external space.
“This research has shown that a least one important function is being done at the level of the spinal cord and it opens up a whole new area of investigation to say, ‘what else is done at the spinal level and what else have we potentially missed in this domain?’” said the study’s senior and supervising researcher Andrew Pruszynski, PhD, assistant professor at Western’s Schulich School of Medicine & Dentistry and Canada Research Chair in Sensorimotor Neuroscience.
All hopes are on Mars to be the next big adventure for mankind, with groups like NASA working hard to make a manned mission to the Red Planet a reality and companies like SpaceX betting big on Earth-to-Mars travel.
SpaceX boss Elon Musk has long promised that living on Mars will be a reality within our lifetimes, even suggesting that he himself might move there at some point in the not-too-distant future. But once all the kinks are ironed out, how much is it going to cost to leave Earth behind and become a full-fledged Martian? Musk thinks he has the answer.
“Very dependent on volume, but I’m confident moving to Mars (return ticket is free) will one day cost less than $500k & maybe even below $100k,” he wrote. “Low enough that most people in advanced economies could sell their home on Earth & move to Mars if they want.”
The extraordinary ambition of Musk’s prediction wasn’t lost on some Twitter users. “Fyre Festival Part Deux,” one replied.
Maybe that skepticism is why, in a follow –up reply, Musk seemed to hedge his bets.
