A Three- and a Four- Body Problem
Last week I wrote about the orbit of Artemis II. The orbit of Artemis I was much more interesting. Because Artemis I was unmanned, it could spend a lot more time in orbit. The Arte...

An elegant mix of math and gravity powers the Artemis II “free return” trajectory from Earth to the moon and back
Researchers have developed a mathematical method that enables more precise calculations of the most economical travel routes between the orbits of celestial bodies. To demonstrate...
30 Jan 2026 blog post from Dr Mike McCulloch, he compared the IVO Quantum drive based on Quantized inertia theory, satellite’s orbit to a nearly identical twin control satellite. F...
There are tens of thousands of near-Earth objects (NEOs) that represent some of the most easily accessible resources in the solar system. Planning trajectories to rendezvous with t...
There are tens of thousands of Near-Earth Objects (NEOs) that represent some of the most easily accessible resources in the solar system. If we can get to them at least. Planning t...
The Artemis II mission launched yesterday. Much like the Apollo 8 mission in 1968, the goal is to go around the moon in preparation for a future mission that will land on the moon....
Needs SpaceX et al to drop prices and give competitors a ride into space to make it work A startup called Orbital has revealed a plan to build a 10,000-satellite neocloud in space...
"One of the questions is what the initial orbit will be for Artemis III."
The astronauts will arrive about 10,300 kilometers beyond our satellite, breaking all previous records for distance from Earth. But how was their route chosen?
A new publication from Bielefeld University sets a benchmark in optimization research. Together with an international team, Professor Michael Römer from the Faculty of Business Adm...
A groundbreaking mathematical method spearheaded by an international team of researchers promises to revolutionize space travel between Earth and the Moon by optimizing fuel consum...
Asteroid mining seems simple in theory. A spacecraft flies up to a giant rock in space, scoops out some material, and either processes it on site or returns it back to a huge centr...

In the last episode of my column in Notices of the American Mathematical Society, we looked at a particle moving in an attractive central force whose strength is proportional to th...
Plotting the optimal trajectory to visit multiple asteroids is a fiendishly difficult take on the Traveling Salesperson problem, but a new mathematical approach has succeeded in so...
The Traveling Salesman is a classic problem in mathematics that requires a solution to the most efficient path to take to visit a given number of cities in the least amount of time...
As the Orion spacecraft hurtles home, friction caused by reentry into Earth's atmosphere will drastically decrease its speed from a potential 25,000 miles per hour (40,000 kilomete...

Stick to haulin' freight. The post Trump Hires Orbital Towing Company to Build Space Interceptors appeared first on Futurism.
Scientists have found a cheaper way to send spacecraft to the Moon by using a gravitational sweet spot as a pit stop, cutting fuel costs by at least 58.80 m/s compared to existing...
A star's mass determines its entire life story, from how it shines to how it dies. For young stars shrouded in dust, getting an accurate mass has long been difficult, but new radio...
