The surface of Terra is close enough to being flat that one can get away with using a two-dimensional map printed on a flat piece of paper. The planets of the solar system can still be managed on a flat map, though not as easily. The planets are all pretty close to the plane of ...
In a nutshell, this article proposes that America’s human spaceflight (HSF) policy be directed to go both to the Moon and Mars simultaneously for exploration and the development of permanent bases. This is based upon accepting the likelihood of the emergence of multiple heavy-lift commercial tra...
In an interview, Harrison pointed out that all of those positions already exist at the Air Force’s space bases across the country and new positions would not be needed. Those positions, he said, would simply transfer from the Air Force to the Space Force or just remain within the Air F...
Regions may have star systems with multiple planets to capture or central locations defended by large bases. Each of the four empires will occupy different regions of the galaxy. From their base, factions invade and conquer their opponent’s sectors to expand their dominion. ...
The system map shows the location of the lost mining ship and of the IPA bases in the Asteroid Belt. Provisions exist for adventures on Martigan III, exploring other planets of the system, determining what went on with the lost ship, and mining the asteroids. Additional suggestions for other...
7.1.4 Norms and Orthonormal Bases A norm on a vector space, V, over K is a function from V to ℝ, denoted || · ||, satisfying, for all v, w∈ V and k∈ K: ||v|| =0 iff v = 0; ||kv|| = |k| ||v||; and ||v + w|| ≤ ||v|| + ||w||. (Note: it fo...
b and c are the bias vectors and U, V, and W are weight matrices to map data from input to hidden unit, hidden to output, and hidden to hidden units, respectively, which are parameters of the model. Now we can formulate our network as follows: zt=Wht−1+Uxt+bht=tanh(zt)ot=Vh...

— NASA, US Air Force unveil new X-plane — the X-66A — to test wild wing design for fuel-efficient flight — DARPA-funded 'Inchworm' robots could help us build moon bases. Here's how — NASA wants to fly this nuclear Dragonfly drone on Saturn's moon Titan. Watch its...
After burning through its fuel, the rocket detached from Odie, leaving the lunar lander to fly solo through space. The robotic explorer then consulted an onboard map of the stars so it could orient itself in space, pointing its solar panels toward the sun’s rays to charge its batteries. ...
