Nuclear fusion propulsion technology has the potential to revolutionize space travel in terms of both speeds and fuel usage. The same kinds of reactions that power the Sun could halve travel times to Mars, or make a journey to Saturn and its moons take just two years rather than eight.

It’s incredibly exciting, but not everyone is convinced this is going to work: the tech needs ultra-high temperatures and pressures to function.

To help prove the viability of the technology, the largest ever fusion rocket engine is now being built by Pulsar Fusion in Bletchley, in the UK.

The thrusters will play an important role on NASA’s Gateway, the outpost orbiting the Moon.

Engineers from NASA and Aerojet Rocketdyne have begun the multiyear qualification testing of the most powerful solar electric propulsion (SEP) thrusters, which are expected to radically change propulsion in space, a press release from the space agency said.

For decades, space research has relied on chemical propulsion to generate millions of pounds of thrust and has attempted to make bigger and more powerful rockets to take us further in our space voyages. While this is a standard even with the most advanced methane-powered rocket engines, it is not necessarily the most efficient way to move about in space.

Now that Virgin Galactic has flown its first commercial spaceflight, it’s ready to take civilians aboard. The company now expects to launch its first private passenger flight, Galactic 2, as soon as August 10th. Virgin isn’t yet revealing the names of everyone involved, but there will be three passengers alongside the usual crew. You can watch a live stream on the company website.

The inaugural commercial flight, Galactic 1, flew in late June. However, all three passengers were Italian government workers (two from the Air Force and one research council member) conducting microgravity studies. While it’s not clear what 02’s civilian crew will do, they can be tourists this time around.

The firm has been ramping up its operations in recent months after numerous delays from previous years. While Galactic 2 is just Virgin’s seventh spaceflight of any kind, it’s the third in 2023. The company says it’s establishing a “regular cadence” of flights, and you can expect them to become relatively routine if this voyage goes as planned.

Earth has often been compared to a spaceship, one that’s successfully orbited our star and the galaxy many times over billions of years. So what about moving our planet or even converting it or another world into a spaceship? Can we use entire planets to cross the intergalactic void to settle planets in distant galaxies or superclusters? And what sort of engine and drive could move a whole planet?

A controversial new type of electric propulsion system that physicists say defies Newton’s Laws of Motion, known as the Quantum Drive, has secured a spot on a SpaceX rocket and will launch into low Earth orbit (LEO) this October.

Designed by IVO Ltd., an electronics prototyping company, the promising yet controversial Quantum Drive could change the future of space travel and, if proven to work, would potentially rewrite or expand many of the accepted principles of inertia and motion that have existed for centuries.

Newtonian Physics Says creating inertia Without Propellant is Impossible.

LOS ANGELES – Artificial intelligence, quantum computing and nuclear power are among the key technologies Lockheed Martin sees as important for future space missions.

Through a project called Destination: Space 2050, Lockheed Martin executives are exploring, for example, how AI could assist scientific exploration of locations where communications with remote sensors would be disrupted by high latency.

In that type of environment, “you really can’t interact with the robotic sensors,” David Lackner, Lockheed Martin senior manager strategy and business development, said during a June 28 webinar. “You have to have something that is super autonomous that can deal with unknown unknowns. We’ve got some really interesting causal autonomy tools that … allow the AI to be super smart about running into something that it hasn’t encountered before.”

It will also reduce travel time to Saturn’s moon Titan to just two years.

Pulsar Fusion, a UK-based space firm, is building a nuclear fusion-based rocket engine that could exceed temperatures on the Sun. The construction of the largest-ever fusion rocket engine has begun, and its exhaust speeds could exceed 500,000 miles per hour.

Nuclear fusion has long been proposed to answer our energy and climate change woes as it promises a cleaner power source. Inspired by the Sun, scientists have been working to build nuclear fusion reactors and have succeeded in generating record-high temperatures but not more energy than they have put in.

It squats on the Las Vegas skyline like an enormous spaceship, black and mysterious – until night falls, when it will glow like the Earth from space.

The MSG Sphere won’t open to the public for almost three more months, when U2 christens the entertainment venue with a series of concerts. But anticipation is growing.

Cue the superlatives. At 366 feet tall and 516 feet wide, it’s being billed as the world’s largest spherical structure. Its bowl-shaped theater reportedly contains the world’s highest-resolution wraparound LED screen. And its exterior is fitted with 1.2 million hockey puck-sized LEDs that can be programmed to flash dynamic imagery on a massive scale – again, reportedly the world’s largest. It was fully illuminated for the first time Tuesday night to celebrate the Fourth of July.

Woven across our universe is a weblike structure of galaxies called the cosmic web. Galaxies are strung along filaments in this vast web, which also contains enormous voids. Now, astronomers using Webb have discovered an early strand of this structure, a long, narrow filament of 10 galaxies that existed just 830 million years after the big bang. The 3 million light-year.

A light year is the distance that a particle of light (photon) will travel in a year—about 10 trillion kilometers (6 trillion miles). It is a useful unit for measuring distances between stars.
