China unveils 2020 Mars rover concept: report
Posted by Andreas Matt in category: space travel
China has unveiled illustrations of a Mars probe and rover it aims to send to the Red Planet at the end of the decade in a mission that faces “unprecedented” challenges, state media said on Wednesday.
China, which is pouring billions into its space programme and working to catch up with the US and Europe, announced in April it aims to send a spacecraft “around 2020” to orbit Mars, land and deploy the rover.
Zhang Rongqiao, chief architect of the project, said Tuesday they were targeting July or August of that year for the launch, the Xinhua news agency reported.

Journey to Mars in Less than Two Days Onboard this Radical Train Concept
Posted by Sean Brazell in categories: engineering, environmental, space travel
As for the maximum distance the train could journey, “There is no limit,” Bombardier asserts. He reckons the first ship would shuttle cargo and travelers between Earth and the Moon—a trip that would take roughly seven hours to complete at the ideal speed of 15 km/s. “The Moon will serve as a launching pad for other projects, because it is easier to assemble and build this kind of train in the absence of gravity,” he says. “And Mars seems to be a good candidate for the next phase, especially if we can terraform it.”
Though intriguing, the notion begs many questions, and likely won’t be viable for eons. “Obviously there is a lot to consider,” the designer admits. “The general purpose here is to devise a system to transport minerals, materials, and humans from one place to the other in our solar system. Solar Express is a basic idea, and we would like to know how we could improve it.”

Venus’ ‘Twin Planet’ Could Still Have Oxygen, Scientists Say
Posted by Karen Hurst in categories: alien life, space travel
# Venus # Oxygen – Venus’ ‘Twin Planet’ Could Still Have Oxygen, Scientists Say : Nine months ago, astronomers announced that they were able to discover a planet that is said to be a twin to Venus. Today, it seems that a new study raises the possibility of the said planet to have oxygen in its atmosphere – don’t mistake it for the next livable planet though – it is said to have hellish temperatures, which automatically rules out the possibility of life.
Dubbed the GJ 1132b, IFL Science noted that it is larger than Earth in size and mass. Temperature-wise, it is considerably hot at 120 to 320 degrees Celsius, but it is still considered cooler than most of the rocky planets previously detected.

A lost spacecraft is talking to NASA again after nearly 2 years in the void
Posted by Karen Hurst in categories: robotics/AI, space travel
Wild stuff.
Somewhere on the other side of the sun, almost directly opposite to Earth, a NASA spacecraft has drifted aimlessly through the void since Oct. 1, 2014, unable to establish contact with our planet.
At least that was the depressing situation until Sunday night.

NASA Funds Plan to Turn Used Rocket Fuel Tanks Into Space Habitats
Posted by Andreas Matt in categories: habitats, space travel
The first stage launches the rocket off of the pad and continues firing for about four minutes. Once the first stage is out of fuel, it separates, and if it’s a SpaceX Falcon 9, flies back home to be reused. If it’s anything else, including the Atlas V, the first stage crash lands in the ocean and sinks. Meanwhile, the second stage fires up its own engine (or engines) to boost the payload the rest of the way into orbit. On the Atlas V, the second stage is called Centaur. Once Centaur gets its payload where it needs to go, it separates, and then suicides down into Earth’s atmosphere.
Getting a payload into space is so expensive because you have to build up this huge and complicated rocket, with engines and guidance systems and fuel tanks and stuff, and then you basically use it for like 15 minutes and throw it all away. This is why SpaceX is trying so hard to recover the first stage of the Falcon 9. But what about the second stage? You’ve got a whole bunch of hardware that made it to orbit, and when getting stuff to orbit costs something like $2,500 per kilogram, you then tell it to go it burn itself up in the atmosphere, because otherwise it’s just useless space junk.

Hmmmm.
Technocrat scientists believe they can ‘code’ any kind of future they want, but what about what everyone else wants? These are the overlords of Technocracy who believe that we should just ‘trust them’ to build Utopia. ⁃ TN Editor.
