The spaceflight to Jupiter and beyond

Image 1) Artist's concept of Jupiter Icy Moons Orbiter.

NASA is looking for contractors for the "Prometheus" or JIMO (Jupiter Icy Moons Orbiter) mission system. And those nuclear-powered unmanned space probes are opening the road to the sample bringing missions to outer solar systems. 

The experiences that are opening the road to the manned missions to the outer solar system. Those missions require more powerful and advanced technology than missions to Mars. 

What if the EEG of the sleeping crew can use to control spacecraft? 

The scientific team talks lucid messages to people's dreams.

The ability to control dreams is one of the most interesting visions in the world of neuroscience. Dreams are the position where the brain can use the most of its capacity. And that time can use to turn the brain into a productive machine. The ability to control dreams is making it possible to create the obsession to make something. But if we will create a system that can interact with sleeping people. That thing makes it possible to communicate with people. 

While they are in anesthesia or even in a coma. Theoretically, it is possible to make a system that projects people's dreams to the computer screens. That thing requires "only" the system that decodes the EEG to the computer. The ability to communicate with brains while the person is sleeping can play a key role in the future spaceflights to the outer solar system. The computer can input data into the brains of the crew members. 

While they are on the extremely long journey to Jupiter. In that kind of journey, long-term anesthesia is required for keeping the social problems minimal. So in that kind of system, the brains of the crew members can use to communicate with computers. That means those people would control the craft by using EEG waves while they are sleeping. Jupiter is maybe the limit for the nuclear rockets.

How a futuristic probe brings samples from Jupiter to Earth?

There is possible to combine flyby and the orbital mission by dropping the sub-craft to the planetary orbiter from the flyby craft. But that sub-craft requires the breaking time. The idea is that the Jupiter craft will make a flyby of Jupiter. 

During that part of the mission, it drops the orbiter craft. Then it can fly to Saturn and use that planet as the gravitational sling that takes it back to Jupiter. There the smaller probe will dock to the main flyby probe. And return to Earth.

And the journey to there and back requires near 4000 days. The flight time to Jupiter is 600 days if the system makes a flyby. But positioning the craft to the orbital trajectory requires 2000 days. And that is one of the biggest problems in space flight. The journey to Jupiter and back requires 11 years. And that means the craft would just visit that planet. That is an extremely long time. And that is one of the limits for the plans to fly to other planets. 

But if we want to fly farther the problem is aging. That means the aging of the DNA must deny. If we want to send living astronauts to another planet or solar system. There is the possibility that in the distant future. Biotechnology can fix the damages to the DNA of the crew. In that system, the DNA of the crew has been stored in the digital memory of the artificial intelligence. 

And then, the nanomachines can replace the damaged DNA while crew members are aging. If the aging of the crew members can deny. By using some other method than cooling them to zero kelvin degrees. That thing makes it possible to use their brains as part of the computer system.

The Daedalus 3 plan. 

As I am written many times in the 1970s British Interplanetary Society created the Daedalus project. The hypothetical unmanned spacecraft can use to travel to Proxima Centauri or Barnard's star. Maybe Daedalus can ever take astronauts to other solar systems. But that craft and its fusion engine could be a powerful tool for traveling inside the solar system. 

But there are made some theoretical mission profiles for visiting the Proxima and Alpha Centauri. 

The thing is that the flight time to Proxima Centauri would be extremely long if the craft must station to the orbit of that star. The Daedalus can reach 25% of the speed of light by using the antimatter engine. But that is very low. That means the hypothetical Daedalus might be an unmanned system controlled by very advanced artificial intelligence. The flyby would be a very good possibility. Because in that case, the craft must not break when it comes to the Proxima system. 

The idea is that the craft would make flyby but in that case, it shoots the sub-probe to the orbiter of the Proxima Centauri. The sub probe would collect samples from the Proxima system. And then the main craft or another Daedalus would use Alpha Centauri as the gravitation sling that would turn in back to Earth. During that process, the sub-probe will get back and dock to Daedalus.
