Physicists reverse time using quantum computer

Posted by in categories: computing, law, quantum physics, space travel

Researchers from the Moscow Institute of Physics and Technology teamed up with colleagues from the U.S. and Switzerland and returned the state of a quantum computer a fraction of a second into the past. They also calculated the probability that an electron in empty interstellar space will spontaneously travel back into its recent past. The study is published in Scientific Reports.

“This is one in a series of papers on the possibility of violating the . That law is closely related to the notion of the arrow of time that posits the one-way direction of time from the past to the future,” said the study’s lead author Gordey Lesovik, who heads the Laboratory of the Physics of Quantum Information Technology at MIPT.

“We began by describing a so-called local perpetual motion machine of the second kind. Then, in December, we published a paper that discusses the violation of the second law via a device called a Maxwell’s demon,” Lesovik said. “The most recent paper approaches the same problem from a third angle: We have artificially created a state that evolves in a direction opposite to that of the thermodynamic arrow of time.”

Spaceflight found to reactivate dormant viruses in astronauts

Posted by in categories: biotech/medical, health, space travel

There are certainly a whole host of technological hurdles to overcome before humans successfully travel to Mars, or beyond, but research is also pointing to a growing assortment of fundamental health challenges that astronauts may face from long stretches of time in space. A recent NASA-funded study has found dormant viruses can reactivate in the human body during spaceflight, presenting yet another physiological problem for scientists to solve before we journey out into deep space.

SpaceX’s Crew Dragon Launch Could Make Space Hotels A Reality

Posted by in category: space travel

With the successful launch and docking of its Crew Dragon spacecraft under its belt – although it still has to stick the landing – SpaceX could soon be launching humans to a number of exciting orbital destinations. And, yes, that includes space hotels.

10 Space Science Stories

Posted by in categories: physics, science, space travel

Humanity will get its first good look at Ceres and Pluto, giving us science writers some new pics to use instead of the same half dozen blurry dots and artist’s conceptions. SpaceX will also attempt a daring landing on a sea platform, and long duration missions aboard the International Space Station will get underway. And key technology headed to space and on Earth may lead the way to opening up the window of gravitational wave astronomy on the universe. Here’s 10 sure-fire bets to watch for in the coming year from Universe Today:

1. LISA Pathfinder

A precursor to a full-fledged gravitational wave detector in space, LISA Pathfinder will be launching atop a Vega rocket from Kourou, French Guiana in July 2015. LISA stands for the Laser Interferometer Space Antenna, and the Pathfinder mission will journey to the L1 Lagrange point between the Earth and the Sun to test key technologies. LISA Pathfinder will pave the way for the full fledged LISA space platform, a series of three free flying spacecraft proposed for launch in the 2030s.

Lockheed Martin’s Compact Fusion Reactor Might Change Humanity Forever

Posted by in categories: nuclear energy, space travel

This is an invention that might possibly modify the civilization as we know it: A compact fusion reactor presented by Skunk Works, the stealth experimental technology section of Lockheed Martin. It’s about the size of a jet engine and it can power airplanes, most likely spaceships, and cities. Skunk Works state that it will be operational in 10 years.

For HyperSciences, geothermal energy builds a path to space

Posted by in categories: business, Elon Musk, space travel, sustainability

These days, it seems anyone wanting to launch rockets will inevitably be compared to Elon Musk and Jeff Bezos, especially if rocket launching isn’t the only business interest on the agenda. Musk has Tesla plus SpaceX, and Bezos has Amazon plus Blue Origin. Now, meet Mark Russell, a disciple of Bezos and rocket engineer who founded HyperSciences, a drilling company that uses aerospace technology to both quickly extract underground geothermal energy and put payloads into orbit at low cost.

The idea of leveraging Earth’s geothermal energy is not a new concept, but the expense and time required to reach the depth needed have been prohibitively expensive. That’s where HyperSciences comes in.

Russell and his team have developed a low-cost, multi-purpose projectile called the HyperDrone that can accelerate to velocities over five times the speed of sound and pulverize hard rock via their HyperDrill. This will enable tunneling speeds that are 5–10 times quicker than conventional methods, and more importantly, it opens up significant market viability in other industries that could benefit, namely when that acceleration is pointed skyward. NASA has already recognized this potential and is a current investor and major partner of HyperSciences.

SpaceX’s Starship prototype moved to launch bad on new rocket transporter

Posted by in category: space travel

Over the last two or so weeks, SpaceX engineers and technicians have continued to make progress on the company’s first full-scale Starship prototype, intended to support experimental suborbital hop tests as early as March or April.

That work reached a peak on March 8th when the massive Starhopper was transported from build site to launch pad on a brand new transporter that was delivered and assembled barely 48 hours prior. Ahead of the suborbital prototype’s move, work has been ongoing to construct a replacement fairing for the partial-fidelity vehicle, although there is a chance that the new BFR-related stainless steel sections being assembled could be the start of the first orbital Starship prototype.

Physicist Brian Cox on how space travel can save the human race – and why there should be a Mars mission

Posted by in categories: Elon Musk, space travel

Professor says a joint mission to Mars would be a ‘unifying force’. He believes commercial space flight by entrepreneurs like Elon Musk, Jeff Bezos and Richard Branson can help colonise other planets and ensure human race survives.
