NASA funded scientist claims new thruster can approach the speed of light

The concept of interstellar travel has fascinated the human race for thousands of years.

(TMU) – The concept of interstellar travel has fascinated the human race for thousands of years. Discoveries made in the last century, however, have both bolstered and dampened that fascination. While the number of habitable star systems available for visitation has grown exponentially, the distance between these systems has grown more bleakly, mathematically daunting.

If we sent our fastest space probe to the nearest star, Alpha Centauri, it would take tens of thousands of years to arrive. While galaxies look like homogenous swirls of star clusters, the reality is we are looking at it from a vast, intergalactic scale; the extraordinary distances between stars still make crewed interstellar travel a dubious proposition that many scientists believe won’t be possible for centuries if at all.

However, in recent years, a number of technological models of propulsion – such as light sails pushed by lasers, ion thrusters, fusion engines, wormholes, and even hydrogen bombs – have made the concept of an interstellar probe that can travel a certain percentage of the speed of light increasingly possible.

“Impossible” EmDrive engine could make interstellar travel a reality

771DFA96-1414-46F7-8E54-8D23D1D98682

Latest research aims to resolve whether the exciting and controversial thruster could actually work.

The EmDrive could usher in an era of interstellar voyages for human beings. Or it could be a failed experiment that unsuccessfully tried to break the laws of physics. A pair of upcoming papers may just settle that decades-long argument.

The EmDrive was first proposed in 2001 by scientist Roger Shawyer. In theory, the drive—also called a radiofrequency resonant cavity thruster—converts electricity into microwaves and forces them through a sealed cone. The microwaves would bounce around the reflective surface of the cone, and since the microwaves carry momentum, they would impart that momentum to that surface. The waves would exert more force on the larger end of the cone than the smaller one, creating enough thrust—without the need for propellant—to push a spacecraft through the vacuum of space. And, the drive could theoretically increase momentum once it starts moving.

China is building a floating spaceport for rocket launches

608F3191-BF36-40D9-95E4-E4793A7781F8

In the near future, launch facilities located at sea are expected to be a lot more common. SpaceX announced that it is hoping to create offshore facilities in the near future for the sake of launching the Starship away from populated areas. And China, the latest member of the superpowers-in-space club, is currently building the “Eastern Aerospace Port” off the coast of Haiyang city in the eastern province of Shandong.

This mobile launch facility is being developed by the China Aerospace Science and Technology Corporation (CASC), the country’s largest aerospace and defense contractor. Once fully operational, it will be used to launch light vehicles, as well as for building and maintaining rockets, satellites, and related space applications. As China’s fifth launch facility, it will give the country’s space program a new degree of flexibility.

The addition of a sea platform will also help mitigate the risk to populated areas. At present, all of China’s other launch facilities are located inland at Jiuquan (northwest China), Taiyuan (north), Xichang (southwest), and the coastal site at Wenchang (south) on the island of Hainan. Launches from these locations often result in spent stages falling back to Earth, which requires extensive safety and cleanup operations.

Here’s how asteroid mining will transform the world

Asteroid mining sounds fantastically futuristic, but it is almost feasible with existing technology.

We have already landed spacecraft on asteroids and taken samples.

Now all of that “simply” needs to be done at a much larger scale mining a well-scouted space rock.

The payoff for humanity will be astronomical.

Virgin Galactic offers peek inside new space plane for tourists

Inside of VSS Unity unveiled, showing the cabin in which six passengers will be able to float in zero gravity on the edge of space

Virgin Galactic has revealed the interior of its centrepiece space plane, showing off a cabin with new custom seats and a “space mirror” in a virtual tour of what its passengers can expect to experience on flights to the edge of space.

For $250,000 a ticket, passengers who have signed up for the suborbital flight aboard the air-launched plane VSS Unity will strap into six tailored seats and be able to peer out of the cabin’s 12 circular windows as they ascend 97km (60 miles) above Earth. The plane has five other windows.

Hope Probe: UAE spacecraft blasts off in first ever mission to Mars

Mission had been delayed twice due to bad weather

The United Arab Emirates has launched its first mission to Mars, the first of three missions to the Red Planet to take place this month.

The Hope Probe launched from Japan’s Tanegashima Space Center for seven-month voyage, facing off bad weather which caused the mission to be delayed twice.

The mission originally intended to leave Earth on 14 July.

Space tourists could ride this cosmic balloon to the edge of space

 CE7E4DC0-DE52-41B8-9898-EE9E207C737D

Competition in the space tourism industry is heating up, and a new company is taking a unique approach to near-space exploration.

The prospect of space travel has long-since enchanted humanity. Now, as competition heats up across the burgeoning spaceflight industry, this sci-fi fantasy may soon become reality. The company Space Perspective is offering a unique transport twist on the standard spacefaring business model. Rather than harnessing the latest propulsion technology or rocket busters, the company is using a pressurized cabin and a high-altitude balloon to chauffeur tourists to the cusp of the final frontier. But how much will it cost? Also, why balloons?

Space Perspective was founded by co-CEOs Jane Poynter and Taber MacCallum. While a balloon may not immediately strike some as the ideal mode of transport for such an undertaking, the “serial entrepreneurs” behind the company have a rich history of lofty ideas tethered to these buoyant instruments.

Send your ashes into orbit for a funeral in space

Services such as Celestis and Aura Flights send remains to the skies in an epic final journey.

Even in the freezing cold, Steven Schnider would often drag his wife Christine outside to look up at the night sky. He’d point out everything from planets to comets to satellites he’d tracked down using an app called Heavens Above.

“He’d say, ‘Do you see it?’ It’s right there. And it would be the faintest little piece of light going across the sky,” Christine recalls. “He was just so excited about it.”

When Steven was close to death in 2017, there was a consensus among family members that a space burial would be the best way to send him off. Their daughter took out her phone, did a quick search and pulled up a company called Celestis.

Last June, a portion of Steven’s ashes — along with cremated remains from over 150 other Celestis clients — were flown into Earth’s orbit aboard SpaceX’s Falcon Heavy rocket, which launched from the Kennedy Space Center in Florida. Another portion of his ashes will fly aboard the Luna 02 mission, which is slated for takeoff in 2022.

“He’d be so excited that he was in space,” Christine says.

NASA is offering $35,000 in prizes to design a toilet that will work on the moon

BD269E6A-F6CF-46E5-9CE1-1CF6E886A337

NASA is seeking new designs for a toilet that will work on the moon.

(CNN)NASA wants you to help put the loo in lunar, so it’s offering $35,000 in prizes to design a toilet that can be used on the moon.

The space agency has set an ambitious goal of sending astronauts back to the moon by 2024 and the crew will obviously have to go to the bathroom during the mission.

NASA may adapt the toilet design for its Artemis lunar lander, so it will need to work both in the microgravity of space, or “zero-g,” and on the moon, where the gravity is about a sixth of what we feel on Earth, according to the design guidelines posted by NASA and HeroX, which allows anyone to create challenges to solve a problem facing the world.

Martian city for the desert outside Dubai

 Dubai is a city where firefighters use jetpacks, archipelagos are built from scratch, and buildings climb into the clouds; a slick metropolis in the middle of a vast red desert. First-time visitors would be forgiven for thinking they had stumbled onto a film set for a sci-fi movie.

Now Dubai is set for what must be its most other-worldly architectural project yet.

In 2017, the United Arab Emirates announced its ambition to colonize Mars within the next 100 years. But architects are already imagining what a Martian city might look like — and planning to recreate it in the desert outside Dubai.

Mars Science City was originally earmarked to cover 176,000 square meters of desert — the size of more than 30 football fields — and cost approximately $135 million.

Intended as a space for Dubai’s Mohammed Bin Rashid Space Centre (MBRSC) to develop the technology needed to colonize Mars, architects Bjarke Ingels Group were asked to design a prototype of a city suitable for sustaining life on Mars — and then adapt it for use in the Emirati desert.

Scientists create world’s most heat resistant material with potential use for spaceplanes

032F18B0-E4E4-4161-A33C-6ABE9DEC99F9

Unmanned aircraft flying in the upper atmosphere.

Reusable spacecraft would make space exploration both more cost-effective and accessible, which is why space agencies have been actively pursuing their development. However, spaceplanes are subjected to extreme temperatures on exiting and re-entering the atmosphere. So, materials which can withstand the scorching temperatures are needed in their construction.

Scientists from the National University of Science and Technology (NUST) in Moscow have now fabricated a ceramic material which is more heat resistant than any other.

The previous material to hold the title of “most heat resistant” was tested in 2016 by a team from the Imperial College London. Using a laser heating technique which allowed them to test the material at extreme temperatures, they calculated that a chemical compound of the elements hafnium, a transition metal, and carbon had the highest melting point ever recorded at the time. Their findings showed hafnium carbide melted at just under 4000 degrees Celsius.
