Grand Challenges Part 2: Orbital Refueling

For every 25 kg of a fully-fueled launch vehicle, only 1 kg is payload to low earth orbit (LEO). For every 1 kg sent to Mars, there is 100 kg of launch vehicle mass. You want to get back from Mars? That’s another topic. With orbital refueling, it is possible to raise the payload ratio […]

Lunar Lava Tubes Larger than Expected

We knew there were lava tubes on the moon and Mars.  But we thought the ones on the moon were no more than 500 meters in diameter.  A recent study of gravity data shows two voids larger than that, and an engineering study shows the tunnels can be up to 5 km across - large […]

EM-Drive, Cannae, and The Implications for Propellantless Rockets

​While much fuss is made over the possibility of EM-Drive, there are actually two propellant-less, low trust concepts being evaluated. Cannae has similar properties, but depends on superconductors to operate. There are plans to do a demonstration satellite in the next few years.In the near term, these rockets could make extensive surveys of the asteroid […]

Ice Deposit on Mars has as much water as Lake Superior

This newly-discovered ice field is half-way between the north pole and the equator.  It contains as much water as Lake Superior, and covers an area the size of New Mexico.  It is between one and ten meters below the surface - very easy to reach by drilling or excavation by future Mars colonists.

Elon Musk Creates Massive Opportunity for Entrepreneurship

“The goal of Space-X is really to build the transport system. It’s like building the Union Pacific Railroad. And once that transport system is built, then there’s a tremendous opportunity for anyone who wants to go to Mars and create something new, or build the foundations of a new planet. So, who wants to be […]
