Who Let the Gas Out? NASA Tank Venting Challenge  Create a concept for tank venting in micro-gravity  IMPORTANT: Participants need to fill out the Challenge Registration form before submitting the solution. Please refer to the Guidelines tab for more information. As space travel extends to greater duration and distance, missions may require a propellant refill in space. To achieve this, spacecraft may require larger tanks and efficient refueling along with tanks that have the capability of isolating propellant from ullage fluid (a gas and vapor mixture) during a vent. The goal of this Challenge is to develop a novel solution for the venting of ullage contents from a partially full propellant tank, in microgravity, with minimal loss of propellant. This ullage venting solution w...

Challenge Overview and Objective Innovative solutions are urgently needed to detect, characterize, track, or remediate small debris to ensure the safety and sustainability of space operations. YOU NEED TO FILL OUT THE REGISTRATION FORM AND BE REGISTERED ON THE FREELANCER.COM PLATFORM BEFORE SUBMITTING THE SOLUTION This competition invites creative minds from around the world to contribute groundbreaking concepts that address the critical issue of small debris in Earth's low-earth orbit (LEO) environment. Low-Earth orbit (often known as LEO) encompasses Earth-centered orbits with an altitude of 2,000 km or less. Low-Earth orbit is considered the area in Earth orbit near enough to Earth for convenient transportation, communication, observation and resupply. This is the area wher...
