The first serious attempt to design a ship capable of travelling to the nearest stars. Weighing 50,000 tonnes, powered by nuclear fusion, travelling at 12% of the speed of light, the journey time would be close to 50 years.

Posted in robotics/AI, space travel | Leave a Comment on Photonic Laser Propulsion to send a 100 kg vehicle to Mars in 3 days and to get to wafercraft to 30% of the speed of light
Philip Lubin describes his appraoch to achieving laser driving spacecraft propulsion in the near term.
100kg robotic craft could be sent to Mars in 3 days.
1kg could go overnight to Mars.
50–100 GW could send a wafercraft to 30% of the speed of light and i would involve 10 minutes.
Yes.
A new video released by the space agency discusses the possibility of speeding up our missions to other worlds by harnessing the power of lasers.
Researchers at the University of California Santa Barbara are aiming to use photonic propulsion technology to get aircraft to relativistic speeds, or more than one tenth of the speed of light.
ABSTRACT
While General Relativity (GR) ranks undoubtedly among the best physics theories ever developed, it is also among those with the most striking implications. In particular, GR admits solutions which allow faster than light motion and consequently time travel. Here we shall consider a “pre-emptive” chronology protection mechanism that destabilises superluminal warp drives via quantum matter back-reaction and hence forbids even the conceptual possibility to use these solutions for building a time machine. This result will be considered both in standard quantum field theory in curved spacetime as well as in the case of a quantum field theory with Lorentz invariance breakdown at high energies. Some lessons and future perspectives will be finally discussed.
NASA’s Space Technology Mission Directorate is seeking proposals from accredited U.S. universities on behalf of outstanding early-career faculty members who are beginning independent research careers. The grants will sponsor research in specific high-priority areas of interest to America’s space program.
Aligned with NASA’s Space Technology Roadmaps and priorities identified by the National Research Council, the agency has identified topic areas that lend themselves to the early stage innovative approaches U.S. universities can offer for solving tough space technology challenges.
“These grants will allow us to support university faculty in conducting research and technology development to solve some of the challenges that we face on our journey to Mars,” said Steve Jurczyk, associate administrator for NASA’s Space Technology Mission Directorate in Washington. “Engaging the creative and innovative researchers at universities across the country provides opportunities to develop space technologies that drive robotic and human exploration of the solar system and beyond.”
It’s an exciting time for space exploration. NASA, private companies, and several countries are all racing to colonize space. Soon we hope to become a multi-planetary species. But why?
This post explores why we’re racing to the Moon and Mars and who will get there and when.
This is Part 2 of our Space GGC Series focused on important issues facing us now:
In the future, we hope to “tour” around the solar system. Indeed, some companies are already working on private space tours. Here, NASA’s JPL gives us a peek at what this space tourism might look like.
NASA’s Jet Propulsion Laboratory (JPL) recently released awesome posters of our solar system, specifically designed at getting people to journey to the stars (or at least some nearby alien planets). “The Vision of the Future” series comprise of seven original posters. In addition to these, there are seven more posters for “Exoplanet Travel Bureau” that were published last year.
Notably, these posters are more than just fantastical imaginings. The designers who created these magnificent posters have been consulting with JPL scientists and engineers to make these tourism scenarios as realistic as they can possibly be. In short, it lets you see what the travel of tomorrow may look like.
“Produced by the Jet Propulsion Lab at NASA, these gloriously retro space posters make a trip to the stars look like a holiday”
The Rise of the Rest and Mars Colonization
The Chinese word for crisis has two characters (危機). The first character represents danger and the second can be interpreted as opportunity, change of time, moment or chance. Even though the meaning of these Chinese characters can vary according to the context and nearby characters, the understanding of crisis (危機) as danger (危) plus opportunity (機) can help us think about the challenges faced by humanity in 2030.
In the coming years, China will have the largest economy of the planet, dethroning the USA to number two, both economically and scientifically. India will also be catching up fast as the third largest economy in the world, and its population will continue increasing after overtaking that of China in 2025. The re-emergence of Asia, as represented by China and India, will create a dramatic shift in power and geopolitics from what has been called the West to the East. The international hegemony enjoyed by the West during the last half millennium will move back to the East, which already led the world in many areas before the European Renaissance.
Fortunately, during the next two decades, the world economy will keep expanding and human conditions will get better throughout the whole planet. Indeed, a rising tide lifts all boats. Poverty will be substantially reduced and the environment will be significantly improved thanks to a growing global conscience and continuous advances in technology. Even Africa, the historic cradle of civilization, but considered a basket case during the last few centuries, will experience its own re-emergence in the world stage. After experiencing growth of 5% during the 2010s, and even higher during the 2020s, most African countries will be joining the rapid development of China and India, like most of the rest of the world.
The world in 2030 will be radically different from the world today. Rapid economic growth and convergence will have lifted the conditions of the bottom of the pyramid, and many people will raise their eyes into outer space. The colonization of Mars will start during the 2020s according to different plans by many governments (like those of China, Europe, India, Japan, Russia, and the USA) and even some private enterprises (for example, MarsOne, SpaceX, and Virgin Galactic).
Exponential Technologies and Immortality
Change is not constant, in fact, change is accelerating very fast. We will see more transformations in the next 20 years than in the past 200 years. Some technologies are radically changing humanity, in general, and also changing human beings, in particular. Many experts now talk about the four sciences and technologies of the future: NBIC (nano-bio-info-cogno). The NBIC fields are converging at an accelerating rate and they will help to transcend many human limitations in order to improve lives all around the world, and eventually beyond our tiny planet.
We might think of nano and bio as the hardware of life, and info and cogno as the software of life. In the next two decades, we will be able to replicate and improve the complexity of both the hardware and software of human beings. The complexity of our hardware is embodied in the human genome and its 3 gigabits of data, while the complexity of our software is implied by the human brain and its 1017 operations per second.
According to some technology trends, we might achieve physical immortality by copying, reproducing, augmenting, and enhancing our current hardware and software. In medicine, some scientists say that aging is actually a disease, but a curable disease. In fact, some cells do not age, for example, bacteria, germinal cells, stem cells, and cancer cells do not go through the aging process. It is fundamental to understand why this happens and use that knowledge to stop aging in more complex organisms like us. By so doing, our hardware might live indefinitely thanks to longevity discoveries related to genetic treatments, regenerative medicine, and stem cell therapies, for example.
We might also reach immortality through backing up our software. Thanks to research like the Human Brain Project in Europe and the BRAIN Initiative in the USA, we will be able to reengineer our brains. As computer-to-brain interfaces keep improving, some scientists believe that we will eventually be able to upload our brains into machines. In the next two decades, we might well see the “death of death”.
Humanity is fast approaching what some people call the “Singularity”: the moment when artificial intelligence will reach human intelligence levels, and then quickly overtake it. Perhaps then some humans might become transhumans and posthumans, changing forever life on Earth and the universe.
