Fuel/ energy efficient method for travel is my guess.


The US Air Force’s unmanned X-37B space plane has now spent more than 500 days orbiting the Earth, without statement or explanation. The 29-foot unmanned plane is part of the Air Force’s orbital program.

Launched May 20, 2015, it is the program’s fourth flight (hence its other name, OTV-4 for Orbital Test Vehicle-4). The first OTV took flight in 2010 and spent 224 days in orbit; two others brought the total number of OTV days in orbit before 2015 to 1,367, according to the Air Force.

The full purpose or intent of the program? The US Air Force remains mum. The Air Force will only say in its program factsheet that the initiative is to “demonstrate technologies for a reliable, reusable, unmanned space test platform for the US Air Force. The primary objectives of the X-37B are twofold: reusable spacecraft technologies for America’s future in space and operating experiments which can be returned to, and examined, on Earth.

NASA-funded project sends holographic recordings of real humans in Virtual Reality to crew members of 12-month Simulated Mars Isolation Study

October 13 2016 — As NASA prepares for its Journey to Mars in mid 2030’s, an experiment recently concluded in a remote University of Hawaii Mars simulation site to study the effects of long term isolation on an international team of six scientists, and the potential for virtual reality as an asynchronous communication tool. In a first of its kind pilot, the subjects at the facility called HI-SEAS have received holographic recordings of astronaut Buzz Aldrin and vocal artist/comedian Reggie Watts, which when viewed in virtual reality, simulate true presence and could help mitigate the feeling of isolation.

The research, led by R&D consulting company SIFT (Smart Information Flow Technologies), is enabled by holographic software company 8i, which developed proprietary technology to bring photorealistic holograms of humans into virtual and augmented reality experiences.

WASHINGTON (AP) — President Barack Obama sought Tuesday to reinvigorate his call for the U.S. to send humans to Mars by the 2030s, showcasing budding partnerships between the U.S. government and commercial companies to develop spacecraft capable of carrying out the extraterrestrial mission.

Obama was calling attention to government contracts awarded to six companies to build prototypes for “habitats” that could sustain human life in deep space. He also said that within two years, private companies will send astronauts to the International Space Station, part of a program to allow companies to use an open docking port on the station to develop their own innovations.

“These missions will teach us how humans can live far from Earth, something we’ll need for the long journey to Mars,” Obama wrote in an op-ed on CNN’s website. He said the ultimate goal is for humans eventually to stay on the red planet “for an extended time.”

We are seeing lot of inventions being made prior to the upcoming Mars missions. However, you don’t have to be into science-fiction to understand that NASA still needs to get a grip on many technical hurdles before our astronauts can put their boots on the red planet safely.

Yes, [Mark Watney](http://www.imdb.com/title/tt3659388/) has become quite a Martian but real humans need more to survive and especially have to consider the *less obvious* things like how to deal with injuries that far away from mother Earth. That can be overlooked, but certainly is important.

As there’s only so much space on a trip to Mars, there will be limited access to medical care due to supply restrictions. Expertise to manage complex medical conditions might also be hard to come by.

It’s been a big year for the ‘impossible’ EM Drive — a new kind of rocket engine that appears to generate thrust without any kind of exhaust or propellant. Back in May, NASA researchers reported a successful 10-week trial of their EM Drive prototype, and inventor Guido Fetta just got approval to test his own version in space.

Now, the UK Intellectual Property Office has released the latest patent application from British EM Drive inventor Roger Shawyer, and he says millions of pounds rest on the success of design within.

“The patent process is a very significant process, it’s not like an academic peer review where everyone hides behind an anonymous review, it’s all out in the open,” Shawyer told Mary-Ann Russon at the International Business Times.

The space race is on, and it’s only a matter of time before humans land on Mars. With several different groups aiming for the red planet, there’s likely to be not one outpost among the stars, but many.

National space agencies and private transport companies are all competing to reach Mars and establish their own base of operations, and they all have very different motivations and ideas on how to govern their colonies once they get there.

If Elon Musk gets his way and manages to lower the cost of a trip to Mars, the floodgates will open and settlers will stream towards the red planet in mass numbers. The resulting chaos is likely to produce several different Martian metropolises with their own character, laws, and forms of government much like the city-states of ancient Greece.

That’s why researchers are hard at work on ways to make spacecraft power systems more efficient, resilient and long-lasting.

“NASA needs reliable long-term power systems to advance exploration of the solar system,” said Jean-Pierre Fleurial, supervisor for the thermal energy conversion research and advancement group at NASA’s Jet Propulsion Laboratory, Pasadena, California. “This is particularly important for the outer planets, where the intensity of sunlight is only a few percent as strong as it is in Earth orbit.”

A cutting-edge development in spacecraft power systems is a class of materials with an unfamiliar name: skutterudites (skut-ta-RU-dites). Researchers are studying the use of these advanced materials in a proposed next-generation power system called an eMMRTG, which stands for Enhanced Multi-Mission Radioisotope Thermoelectric Generator.

The stability of a light sail riding on a laser beam is analyzed both analytically and numerically. Conical sails on Gaussian beams, which have been studied in the past, are shown to be unstable in general. A new architecture for a passively stable sail and beam configuration is proposed. The novel spherical shell sail design is capable of “beam riding” without the need for active feedback control. Full three-dimensional ray-tracing simulations are performed to verify our analytical results.

President Obama said Tuesday that he wants private companies to help send humans to Mars by the 2030s.

Obama first said in 2010 he wanted to send astronauts “to orbit Mars and return them safely to Earth” by the mid-2030s with “a landing on Mars” to follow. In that speech at the Kennedy Space Center, Obama added that he expected to see such a landing in his lifetime.

In an opinion article Tuesday on CNN.com, Obama said private companies would be key to those lofty goals.

As reported by the AP, President Obama Mars op-ed published at CNN today paints a vivid picture in which NASA — working in concert with other agencies and private industry — would sometime after 2030 finally make an expedition to the planet Mars. But is the Barack Obama Mars vision for NASA a tangible possibility, or will Elon Musk and SpaceX beat NASA to Mars long before that?
