Chandrayaan-3 vs Russia’s Luna-25; Race to Moon’s south pole position

Posted by in category: space travel

Russia successfully launched its inaugural moon-landing spacecraft on Friday in 47 years. The mission aims to achieve the distinction of being the first country to achieve a gentle landing on the lunar south pole, an area thought to contain valuable reservoirs of water ice.

As per a report by Reuters, Russia’s recent lunar mission, it’s inaugural one since 1976, is in a competitive race with India, which sent its Chandrayaan-3 lunar lander to space last month.

Moreover, it’s part of a larger competition involving the United States and China, both of whom have well-developed lunar exploration initiatives that focus on the southern region of the Moon.

Zero, the eco-friendly rocket, to begin testing in Japan

Posted by in category: space travel

The private space firm, Interstellar Technologies, aims for an orbital launch by 2025.

Interstellar Technologies, a Japanese startup that has successfully launched three suborbital rockets, is now gearing up for its first orbital mission. The company plans to conduct a static fire test of its Zero rocket later this year, which will be a crucial step towards launching it into orbit by 2025.

High Voltage Ion Engines Take Trip On The High Seas

Posted by in category: space travel

Over the last several months, we’ve been enjoying a front-row seat as [Jay Bowles] of Plasma Channel has been developing and perfecting his design for a high voltage multi-stage ionic thruster. With each installment, the unit has become smaller, lighter, and more powerful. Which is important, as the ultimate goal is to power an RC aircraft with them.

There’s still plenty of work to be done before [Jay] will be able to take his creation skyward, but he’s making all the right moves. As a step towards his goal, he recently teamed up with [RcTestFlight] to attach a pair of his thrusters — which have again been further tweaked and refined since we last saw them — to a custom catamaran hull. The result is a futuristic craft that skims across the water with no moving parts and no noise…if you don’t count the occasional stray arc from the 40,000 volts screaming through its experimental thrusters, anyway.

These new photos of SpaceX’s giant Starship Booster 9 engine test are just gorgeous

Posted by in category: space travel

The immense power of SpaceX’s Starship Super Heavy booster is on glorious display in newly released photos of a recent engine test.

That test occurred on Sunday (Aug. 6), when SpaceX briefly ignited the 33 Raptor engines of a Super Heavy prototype known as Booster 9 at the company’s Starbase site in South Texas.

NASA’s Building a Nuclear Rocket That Would Get Us to Mars in Just 6 Weeks

Posted by in categories: chemistry, nuclear energy, space travel

Deep space is a hostile environment for humans, which makes the long journey to Mars a serious stumbling block for manned missions. A nuclear-powered rocket could slash the journey time, and NASA has announced plans to test the technology by 2027 at the latest.

Most spacecraft to date have used chemical rockets packed with fuel and oxidizer, which rely on combustion to propel them through space. A nuclear-powered rocket would instead use a fission reactor to heat liquid hydrogen to very high temperatures and then blast it out the back of the spacecraft.

These kinds of engines could be up to three times more efficient than those in conventional rockets, and could cut the time to transit from Earth to Mars from roughly seven months to as little as six weeks. NASA has teamed up with DARPA to make the idea a reality, signing a deal with defense contractor Lockheed Martin to launch a working prototype into space as early as 2025.

Historic Chandrayaan-3 Moon Mission Sends Breathtaking Photos Of Lunar Surface

Posted by in category: space travel

The Indian Space Research Organisation (ISRO) shared some spectacular images from its Chandrayann-3 mission, showcasing the monumental moment in India’s space history. This marks the country’s third lunar exploration mission which will also include a lunar landing of a rover.

Chandrayann-3 launched on July 14, 2023, from the Satish Dhawan Space Centre in Sriharikota, India, and is made up of a lunar lander, propulsion module, and a rover. If the Indian spacecraft is able to successfully land on the moon, it would make India only the fourth country to land a spacecraft on the surface of the moon, with the other three being the United States, Russia, and China. However, before the lunar landing is attempted, Chandrayann-3 has sent back some stunning images of the lunar surface.

LK-99: Diamagnetc Semiconductor, Not Superconductor?

Posted by in categories: materials, space travel

Every so often, along comes a story which, like [Fox Mulder] with his unexplained phenomena, we want to believe. EM drives and cold fusion for example would be the coolest of the cool if they worked, but sadly they crumbled when subjected to scientific inquiry outside the labs of their originators. The jury’s still out on the latest example, a claimed room-temperature superconductor, but it’s starting to seem that it might instead be a diamagnetic semiconductor.

We covered some of the story surrounding the announcement of LK-99 and subsequent reports of it levitating under magnetic fields, but today’s installment comes courtesy of a team from Beihang University in Beijing. They’ve published a paper in which they characterize their sample of LK-99, and sadly according to them it’s no superconductor.

Instead it’s a diamagnetic semiconductor, something that in itself probably bears some explanation. We’re guessing most readers will be familiar with semiconductors, but diamagnetic substances possess the property of having an external magnetic field induce an internal magnetic field in the opposite direction. This means that they will levitate in a magnetic field, but not due to the Meissner effect, the property of superconductors which causes magnetic field to flow round their outside. The Beijing team have shown by measuring the resistance of the sample that it’s not a superconductor.
