After an initial focus on scientific research, including Sierra’s partnership with Jeff Bezos’s Blue Origins on developing a private space station, the Dream Chaser will be involved in commercial operations by hauling cargo and shuttling scientists and researchers to and from space stations.

Both Sierra Space and Radian also have space-tourism aspirations that go beyond much of what’s currently available, including 11-minute flights by Virgin Galactic and Blue Origin, and longer space-balloon flights by companies like Space Perspective and Zephalto that do not reach Low Earth Orbit. “Passengers will be able to go up and stay in orbit,” says Humphrey, whose company has the most developed passenger plans right now. “We can go around the planet in about 95 minutes, so a typical trip will probably be three laps.”

Visits to one or more of the six space stations currently under development lie ahead as well. “We’re calling it purposeful tourism,” says Angie Wise, Sierra’s chief safety officer and SVP of mission and quality assurance. “You’ll get the experience of going to space, but we’ll also put you to work helping with experiments.”

The two astronauts who made Boeing Starliner’s initial crewed flight test in June have now scheduled to return to Earth after their much-awaited return.

NASA astronauts Suni Williams and Butch Wilmore will be leaving the International Space Station (ISS) days after the landing of SpaceX’s next Crew-10 mission.

Crew-10, which has four astronauts on board, will launch next week and will take the place of the Crew-9 team that is currently on the ISS.

Intuitive Machines’ Athena lander is on the moon’s surface but its status is unclear. Second time unlucky: A US company’s lunar lander appears to have touched down at a wonky angle on Thursday, an embarrassing repeat of its previous mission’s less-than-perfect landing last year.

[TIME SUBJECT TO CHANGE] This is the eighth fully integrated test flight of Starship with its Super Heavy booster, the largest and most powerful rocket to ever fly. This is the second launch of the new Starship upper stage with many tweaks, bringing it closer to full functionality.

If all goes well, Starship will softly splashdown in the Indian Ocean about 66 minutes after it lifts off from Starbase, TX, having performed a Raptor relight test and deploying 4 Starlink mass simulators. SpaceX will hopefully be attempting to catch the Super Heavy booster with the launch tower again, which would be the third catch of the booster.

In human engineering, we design systems to be predictable and controlled. By contrast, nature thrives on systems where simple rules generate rich, emergent complexity. The computational nature of the universe explains how simplicity can generate the complexity we see in natural phenomena. Imagine being able to understand everything about the universe and solve all its mysteries by a computational approach that uses very simple rules. Instead of being limited to mathematical equations, using very basic computational rules, we might be able to figure out and describe everything in the universe, like what happened at the very beginning? What is energy? What’s the nature of dark matter? Is traveling faster than light possible? What is consciousness? Is there free will? How can we unify different theories of physics into one ultimate theory of everything?

This paradigm goes against the traditional notion that complexity in nature must arise from complicated origins. It claims that simplicity in fundamental rules can produce astonishing complexity in behavior. Entering the Wolfram’s physics project: The computational universe!

In classical electromagnetism, electric and magnetic fields are the fundamental entities responsible for all physical effects. There is a compact formulation of electromagnetism that expresses the fields in terms of another quantity known as the electromagnetic potential, which can have a value everywhere in space. The fields are easily derived theoretically from the potential, but the potential itself was taken to be purely a mathematical device, with no physical meaning.

In quantum mechanics, shifts in the electromagnetic potential alter the description of a charged particle only by shifting its phase—that is, by advancing or retarding the crests and troughs in its quantum wave function. In general, however, such a phase change does not lead to any difference in the measurable properties of a particle.

But in 1959 Yakir Aharonov and David Bohm of the University of Bristol, UK, devised a thought experiment that linked the potential to a measurable result. In their scenario, a beam of electrons is split, with the two halves made to travel around opposite sides of a cylindrical electromagnet, or solenoid. The magnetic field is concentrated inside the solenoid and can be made arbitrarily weak outside by making the cylinder extremely narrow. So Aharonov and Bohm argued that the two electron paths can travel through an essentially field-free region that surrounds the concentrated field within the electromagnet.
