We propose a novel spacesuit intelligent architecture for extravehicular activity (EVA) operations on Mars and other planetary environments that increases human performance by an order of magnitude on several quantifiable fronts for exploration missions. The proposed SmartSuit spacesuit, while gas-pressurized, also incorporates soft-robotics technology that allows astronauts to be highly mobile and better interact with their surroundings. The spacesuit also incorporates a soft and stretchable self-healing skin (or membrane) located in the outer layer that not only protects the astronaut but also collects data through integrated, transparent sensors embedded in the membrane. These sensors are capable of visually displaying environmental and membrane structural information, providing visual feedback to the wearer about the surroundings.

The hybrid and intelligent spacesuit proposed will be designed with the philosophy of enhancing motion and dexterity, reparability and sensor integration to interact with the soundings and detect damage. The proposed hybrid technology adding full-body softrobotic elements to the gas-pressurized spacesuit will enable enhanced dexterity, increased comfort, and a feeling of normalcy that will facilitate both scientific and exploration operations on planetary missions like those expected for Mars’ surface. Additionally, the soft-robotic layer has the potential to provide some level of mechanical counterpressure (MCP) to the wearer, thus decreasing the gas-operating pressure within the suit, therefore reducing the time needed for pre-breathing protocols while enhancing even more the mobility, which has a direct impact on the duration, metabolic cost, and fatigue associated with an EVA. We expect the proposed spacesuit technology to also reduce the numerous spacesuit-fit injuries and discomfort experienced by present astronauts due to the current highly pressurized spacesuits with no robotic assistance. Our proposed spacesuit significantly improves on the state of the art in spacesuit design, addressing many issues in surface mobility, reparability and re-usability, safety, EVA preparation time, EVA duration time, and both physical and psychological fatigue. The Phase 1 effort constitutes advancement of this concept from TRL 1 to TRL 2.

The proposed project will investigate the trade-space of materials and sensor architectures, leading to design principles and sizing estimates of a candidate spacesuit. We propose to prove its feasibility and whether SmartSuit will achieve the science and exploration objectives articulated in the current Mars Design Reference Architecture 5.0. At the end of the phase I, we will outline the SmartSuit system design and concept of operations, including rationales for material, sensor, and display technology selection. It will also detail the layer breakdown and composition of such a suit. PI Diaz Artiles will lead the mission architecture work of this study, including a comprehensive biomechanical and human performance analysis. Co-I Shepherd will analyze material and mechanical metrics for manufacturing the SmartSuit and will also perform preliminary experimental validation of its core concepts (i.e. joint torques and MCP measurement, basic locomotion, relevant environmental sensing and display, and environmental stability).

Superfast data processing using light pulses instead of electricity has been created by scientists.

The invention uses magnets to record computer data which consume virtually zero energy, solving the dilemma of how to create faster data processing speeds without the accompanying high energy costs.

Today's data centre servers consume between 2 to 5% of global electricity consumption, producing heat which in turn requires more power to cool the servers.

The problem is so acute that Microsoft has even submerged hundreds of its data centre services in the ocean in an effort to keep them cool and cut costs.

Most data are encoded as binary information (0 or 1 respectively) through the orientation of tiny magnets, called spins, in magnetic hard-drives. The magnetic read/write head is used to set or retrieve information using electrical currents which dissipate huge amounts of energy.

Now an international team publishing in Nature has solved the problem by replacing electricity with extremely short pulses of light -- the duration of one trillionth of a second -- concentrated by special antennas on top of a magnet.

This new method is superfast but so energy efficient that the temperature of the magnet does not increase at all.

The team includes Dr Rostislav Mikhaylovskiy, formerly at Radboud University and now Lancaster University, Stefan Schlauderer, Dr Christoph Lange and Professor Rupert Huber from Regensburg University, Professor Alexey Kimel from Radboud University and Professor Anatoly Zvezdin from the Russian Academy of Sciences.

They demonstrated this new method by pulsing a magnet with ultrashort light bursts (the duration of a millionth of a millionth of a second) at frequencies in the far infrared, the so called terahertz spectral range.

However, even the strongest existing sources of the terahertz light did not provide strong enough pulses to switch the orientation of a magnet to date.

The breakthrough was achieved by utilizing the efficient interaction mechanism of coupling between spins and terahertz electric field, which was discovered by the same team.

The scientists then developed and fabricated a very small antenna on top of the magnet to concentrate and thereby enhance the electric field of light. This strongest local electric field was sufficient to navigate the magnetization of the magnet to its new orientation in just one trillionth of a second.

The temperature of the magnet did not increase at all as this process requires energy of only one quantum of the terahertz light -- a photon -- per spin.

Dr Mikhaylovskiy said: "The record-low energy loss makes this approach scalable.

Future storage devices would also exploit the excellent spatial definition of antenna structures enabling practical magnetic memories with simultaneously maximal energy efficiency and speed."

He plans to carry out further research using the new ultrafast laser at Lancaster University together with accelerators at the Cockroft Institute which are able to generate intense pulses of light to allow switching magnets and to determine the practical and fundamental speed and energy limits of magnetic recording.
