Abstract
AbstractThe space debris management and alleviation in the microgravity environment is a dynamic research theme of contemporary interest. Herein, we provide a theoretical proof of the concept of a lucrative energy conversion system that is capable of changing the space debris into useful powders in the International Space Station (ISS) for various bids. A specially designed broom is adapted to collect the space debris of various sizes. An optical sorting method is proposed for the debris segregation in the ISS by creating an artificial gravitational field. It could be done by using the frame‐dragging effect or gravitomagnetism. An induction furnace is facilitated for converting the segregated metal‐scrap into liquid metal. A fuel‐cell aided water atomization method is proposed for transforming the liquid debris into metal powder. The high‐energetic metal powders obtained from the space debris could be employed for producing propellants for useful aerospace applications, and the silicon powder obtained could be used for making soil for fostering the pharmaceutical‐flora in the space lab in the future aiming for the scarce‐drug discoveries for high‐endurance health care management. The proposed energy conversion system is a possible alternative for the space debris extenuation and its real applications in orbiting laboratories through the international collaboration for the benefits to humanity.
Highlights
The International Space Station (ISS) is a unique scientific podium and an orbiting laboratory that has facilitated interdisciplinary researchers in 106 countries to conduct various in vitro trials in microgravity
The feedback-controlled variable sweeping speed dual-head electromagnetic (DHEM) space broom will be capable of capturing all the space debris nearing to the ISS including the nonfunctional objects having an average size between 1 and 10 cm, which are moving with different velocities and directions and polluting the space environment and creating risk to operational satellites and space vehicles
A theoretical proof of the concept complemented with the pragmatic methodological approach has been established for converting space debris lucratively into fuels and for building soil from silicon powder for fostering the pharmaceutical flora in the space lab of ISS for the drug discoveries
Summary
The International Space Station (ISS) is a unique scientific podium and an orbiting laboratory that has facilitated interdisciplinary researchers in 106 countries to conduct various in vitro trials in microgravity. Literature review reveals that through fundamental research and development a few products and services derived from space station activities are entering the souk and furthering healthy and peaceful life on Earth,[1] which is motivating us to propose more challenging research in ISS It is evident from the executive summary of ISS, which encapsulates the achievements of innovative research on the orbiting laboratory that had created a positive impact on the quality of life on Earth and the future scope of the interdisciplinary researches globally for creating an impact on scientific advancement.[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16] we conduct theoretical studies for providing the proof of the concept of space debris recycling and energy conversion system in a microgravity environment with an intention to carry out real-time experiments in the space platform through the multinational collaboration with wide scope and benefits to humanity. The specially separated silicon powders are used for building feigned soil for nurturing pharmaceutical flora in the ISS for the scarce drug discovery for the high-endurance health care management.[3,24,25] An inclusive layout of the proposed methodology for space debris mitigation and the energy conversion technique are described in the subsequent section
