Abstract: The advances in solar technology and electric propulsion now offer the promise of new, very capable space transport systems that will allow us to effectively explore the solar system. NASA has developed many concepts of space-powered spacecraft with power levels ranging from tens to hundreds of kilowatts for robotic and asteroid-driven missions and Mars. This paper describes two electricalchemical propulsion concepts developed over the last 5 years and discusses how they could be used to humanize the solar system. A possible sustainable solution for the supply of spacecraft power would be to achieve and utilization nuclear fusion energy. The paper briefly presents some contributions to obtaining nuclear fusion energy as a viable alternative to current energies. For the energy of spacecraft of the future Hunter Renfrow Limited Jersey , the combination of photovoltaic energy (obtained from the stars) and that produced by a nuclear reactor on fusion is essential. NASA is developing a strategy to send a crew to Mars by 2030. To achieve this goal, NASA plans to develop the technology for long-haul flights including advanced transportation work and living systems. Among these technologies, Solar Electric Propulsion (PES) has been identified as very effective in moving large masses through interplanetary space. For decades it has been known that missions outside the low Earth's orbit can be made cost-effective by PSA Foster Moreau Limited Jersey , but yet such space missions have not yet been done because the manufacturing technology is not advanced enough. NASA's recent investments in solar power systems and propulsion systems have now matured so that the 50 kW PSA is already ready to be put on flight missions. It has been demonstrated analytically that these technologies can be resized to systems with the power of several hundred kilowatts.

Introduction
NASA is developing a strategy to send a crew to Mars by 2030. To achieve this goal, NASA plans to develop the technology for long-haul flights including advanced transportation work and living systems. Among these technologies Maxx Crosby Limited Jersey , solar electric propulsion (PES) has been identified as very effective in moving large masses through interplanetary space.
For decades it has been known that missions outside the low Earth's orbit can be made cost-effective by PSA, but yet such space missions have not yet been done because the manufacturing technology is not advanced enough. NASA's recent investments in solar power systems and propulsion systems have now matured so that the 50 kW PSA is already ready to be put on flight missions.
It has been demonstrated analytically that these technologies can be resized to systems with the power of several hundred kilowatts.
These technologies are expected to be demonstrated on missions that are increasingly distant from the earth, gaining confidence in this system before embarking on Earth-independent missions.
These missions will advance the human exploration capability of the current Trayvon Mullen Limited Jersey , earth-dependent phase.

Methods and Materials
Recently, NASA has developed two technologies that are critical to the PES high power system: (1) Highly resistant flexible solar panels and (2) HET magnetic protection systems. Both technologies have been built and tested to demonstrate their availability in PES operation at 50 kW. A key component of these flexible solar panels is their very small mass and very small storage space. A key feature of the propeller is its ability to process a large amount of propellant with a very low degradation factor for High-delta-V missions. Both technologies can be quickly swept at a much higher power level. Flexible solar panels are based on new structures that offer a large, small volume solar collector area. To accomplish this Johnathan Abram Limited Jersey , tensile nets instead of rigid panels were used to reduce weight and storage. Two models of flexible panels were built.
One with a rectangular launch design called "Roll-Out Solar Array" (ROSA).
The second is a fan-fold circular design called "MegaFlex from ATK orbit".
ROSA is deployed by a dampened release of stress-energy stored in rolled-up composite arms extending a photovoltaic sheet attached to a rod connecting the outer tips of the two arms. MegaFLex runs through a motorized band that first extends an articulated arm and then rotates a 360° swing panel to unroll a photovoltaic blanket. The arm increases the radius of the circular tree without increasing the length of the panel. The development engineering unit (UID) of each design was built to produce 20kW nominal power using the triple-junction photovoltaic cell standard. Acoustic and vibratory tests were made with the photovoltaic cells in operation to determine the resistance to launch (EDHE-Energy and Power, NASA).
Deployment tests were performed in vacuum at + - 60 degrees to determine autonomous functionality under relevant conditions.
Strength tests and resistance were also made.
These tests have convinced NASA that both designs are ready to be incorporated into a mission that normally requires 40 kW of solar power.
