Carnival of Space #370

Hi all! Here is a new edition of COS for you all to enjoy. Amazing things happen in the heavens above us all the time, so relax and find out a little about the newest stuff

  • Aquarius a nuclear thermal rocket that uses water heated to over 3000 degrees celsius to solve many human interplanetary transportation issues.Attributes of a reusable interplanetary human spaceflight transport are proposed and applied to example transits between the Earth/Moon system and Deimos, the outer moon of Mars. Because the transport is 54% water by mass at an interplanetary departure, it is christened Aquarius. In addition to supporting crew hydration/hygiene, water aboard Aquarius serves as propellant and as enhanced crew habitat radiation shielding during interplanetary transit. Key infrastructure and technology supporting Aquarius operations include pre-emplaced consumables and subsurface habitat at Deimos with crew radiation shielding equivalent to sea level on Earth, resupply in a selenocentric distant retrograde orbit, and nuclear thermal propulsion.

    Advancing in-space nuclear thermal propulsion (NTP) technology to the point where fission reactor core temperatures exceeding 3000° C can be achieved during major translational maneuvers (burns). Under these conditions, water molecules pumped into the core will disassociate into hydrogen and oxygen atoms, and specific impulse ISP near 1000 s could be achieved. This level of efficiency, twice that attainable with chemical propulsion, dramatically reduces total mass for an interplanetary transport of specified payload mass.
