hydrogen peroxide fuel comes in at around $10.36 per kilogram, while hydrazine topped the cost chart at around $75.8/kg.

NASA’s DART mission wasn’t designed to study—it was designed to hit. A 570 kg spacecraft, no bigger than a fridge, ...

So too with the 47-year old Voyager 1 spacecraft and its hydrazine thrusters. Over the decades silicon dioxide from an aging rubber diaphragm in the fuel tank has been depositing on the inside of ...

Each Voyager carries a set of primary roll thrusters and an identical backup set. Voyager 1’s primaries stopped firing in 2004 when two tiny heater circuits lost power, preventing the hydrazine fuel ...

meaning we can use pure hydrazine for normal (monopropellant) thrusters. … But then we actually use the decomposed gases to get the high efficiency performance,” he said, adding that Agile is ...

Before assembly in a propulsion device, Miles Space captured imagery during tests of five thruster heads. The imagery was captured with long-exposure photography. SAN FRANCISCO – Miles Space has ...

To fuel the thrusters, liquid hydrazine is converted into gas and released in about 40 short puffs per day to keep Voyager 1 oriented correctly. Over time, engineers discovered that a fuel tube ...

But the team at NASA was not about to be defeated by some clogged tubes. The thrusters operate on liquid hydrazine that, once turned into gas, is released in short puffs to direct the spacecraft’s ...
