NASA satellite prepares to complete a successful green propellant demo operation

A NASA-funded booster lifted off from SpaceX’s Falcon Heavy Rocket has commenced on thruster firings operation. Those thrusters will then fall out of the orbit following its successful illustration of how sufficient the non-toxic fuel will fly the future space operations.

The Green Propellant Infusion Mission spaceship is in its last phase of the in-orbit test movement aimed at asserting how useful the non-toxic fuel is and if it can replace hydrazine. Liquid hydrazine needs proper care before lifting off any ship into space. 

In recent years, ground teams tested the five thrusters across various models found on the GPIM spaceship. The modes will be tested to determine the thrusters’ ability to control the spaceship’s height and to point. 

Brian Marotta, GPIM’s principal chief at Ball Aerospace and Technologies Corp., which manufactures spaceships for NASA, said that GPIM has managed to carry out its designated operation. He added that his company flies an advanced technology on a competent platform. 

The spaceship has started its final phase of burning the thrusters to lower the trajectory of the satellite to about 180 kilometers. At the start of this month, during the 34th Annual Small Satellite Summit, Marotta confirmed that the journey would be made by the end of August. While on the 180 kilometers-altitude, the spacecraft, shaped like a refrigerator, will succumb to aerodynamic pull back to space during re-entry and then burn up after some weeks. 

The GPIM mission costs $65 million, and its primary function is to examine how hydroxyl ammonium nitrate fuel works together with AF-M315E. The fuel could replace the hydrazine that was used to drive satellite structures. On many occasions, hydrazine is mixed together with nitrogen peroxide, a very poisonous compound to drive little moving thrusters aboard the satellite.

Technicians can fill up the AF-M315E blend onto a spaceship without self-contained protective suits, which prevents any poisonous leakage from reaching their bodies. The greens blend has a high viscosity and denser, enabling the AF-M315E to fit in the same tank volume space. As a result, the satellite propulsion system gets improved. 

The AF-M315E fuel cannot freeze while in space than hydrazine, which needs more heat to remain in a liquid state. Hydrazine quickly burns with other chemicals such as aa nitrogen peroxide upon mixing. The AF-M315E fuel requires more and intense heat to cook, proving its safety while handling.
