Future of space propulsion
The arena of space propulsion technology has been witnessing several advances.
Recently, an Italy-based research team revealed that they are working on developing a space propulsion system that will use water as fuel.
Scientists are also testing the concept of lightsails that use the pressure from lasers or starlight to propel spacecraft.
However, it must be noted that these technologies are still in their nascent stages, and it may take years before they can be used in real-world missions.
