This compares some of the ringworlds, centrifuges, space stations, and ships that use spin to make gravity. It also try’s to show how the variables of artificial gravity are used to make centripetal acceleration into spin gravity.

NASA’s Artemis project aims to put humans on the moon for the first time in more than half a century. Japan is slated to take part in this program, providing both astronauts and a rover to aid in exploration on the lunar surface. A look at the possibility of a made-in-Japan vehicle on the moon in the next decade.

The goal of enabling extended deep-space exploration is driving NASA, space agencies, and private players to explore nuclear power solutions.

Recently, two Southern California-based startups, Exlabs and Antares Nuclear, announced a partnership to advance deep-space missions with nuclear-powered spacecraft.

SpaceNews reported that the Exlabs’ Science Exploration and Resource Vehicle (SERV) spacecraft will be equipped with Antares microreactors.

Somehow, we all know how a warp drive works. You’re in your spaceship and you need to get to another star. So you press a button or flip a switch or pull a lever and your ship just goes fast. Like really fast. Faster than the speed of light. Fast enough that you can get to your next destination by the end of the next commercial break.

Warp drives are staples of science fiction. And in 1994, they became a part of science fact. That’s when Mexican physicist Miguel Alcubierre, who was inspired by Star Trek, decided to see if it was possible to build a warp drive. Not like actually build one with wrenches and pipes, but to see if it was even possible to be allowed to build a warp drive given our current knowledge of physics.

Physics is just a mathematical exploration of the natural universe, and the natural universe appears to play by certain rules. Certain actions are allowed, and other actions are not allowed. And the actions that are allowed have to proceed in a certain orderly fashion. Physics tries to capture all of those rules and express them in mathematical form. So Alcubierre wondered: does our knowledge of how nature works permit a warp drive or not?

Interstellar objects are among the last unexplored classes of solar system objects, holding tantalizing information about primitive materials from exoplanetary star systems. They pass through our solar system only once in their lifetime at speeds of tens of kilometers per second, making them elusive.

Hiroyasu Tsukamoto, a faculty member in the Department of Aerospace Engineering in the Grainger College of Engineering, University of Illinois Urbana-Champaign, has developed Neural-Rendezvous—a -driven guidance and control framework to autonomously encounter these extremely fast-moving objects.

The research is published in the Journal of Guidance, Control, and Dynamics and on the arXiv preprint server.

A private lunar lander has captured the first high-definition sunset pictures from the moon.

Firefly Aerospace and NASA released the stunning photos Tuesday, taken before the Blue Ghost lander fell silent over the weekend. One shot included Venus in the distance.

Firefly’s Blue Ghost landed on the on March 2, the first private spacecraft to touch down upright and perform its entire mission. It kept taking pictures and collecting science data five hours into the lunar night before it died for lack of solar energy.

On the heels of Cedar Park-based Firefly Aerospace Inc. successfully putting a lunar lander on the Moon, counties adjacent to Austin are taking a step to grow the Central Texas space industry.

The Williamson County Commissioners Court on March 11 unanimously approved the creation and bylaws of the Central Texas Spaceport Development Corp., an entity being formed in partnership with Burnet County.

Additional steps remain, including the filing of articles of incorporation and the appointment of a seven-member oversight board. Burnet County is scheduled to vote on the plan March 25.

Plymouth, Mich. – For six days, over 2,050 miles and through different climate zones to the Arctic Circle: On an unusual test drive, a Bosch development team successfully tested the new hydraulic brake-by-wire system from Bosch for the first time on public roads. What sets brake-by-wire apart: This solution completely eliminates the mechanical connection between the brake pedal and the brake system. The driver’s brake request is transmitted to the brake-by-wire system purely as an electrical signal via redundant signal lines. For this fundamentally new approach, Bosch offers a robust and efficient solution with two independent hydraulic brake actuators – a by-wire brake actuator and an ESP®. Today’s brake systems, such as the integrated power brake from Bosch, still ensure the required redundancy in the event of a fault via a mechanical connection to the brake pedal. This coupling via an input rod to the brake pedal is eliminated in the new Bosch brake-by-wire solution.

Advantages of the Bosch brake-by-wire system

New freedom in installation: Due to the omission of the mechanical connection, there is no longer any need to mount the brake system components at the vehicle’s firewall. Instead, the components can now be installed where it is most optimal in terms of crash safety, NVH, and manufacturing. The flexibility in choosing where to install the brake actuators helps to avoid the need for different variants for right-hand and left-hand drive vehicles. By-wire technology enables new pedal concepts with significantly shorter brake pedal travel to create space for new interior designs. The hydraulic brake-by-wire solution from Bosch is based on proven brake system technology and is a combination of a by-wire brake actuator and an ESP®. Its slim design saves installation space and reduces the weight of the brake system. Since both the by-wire brake actuator and the ESP® are assigned to different channels of the redundant electrical system, they can each independently build up the required brake pressure at all four wheel brakes in the event of a fault. Therefore, this Bosch solution is also suitable for highly automated vehicles, meeting the protection of the brake system required for safety reasons.
