| Some 55 tons of propellant per second will be burned by the booster with the goal of producing 3.6 million lb of maximum thrust, equivalent to the power of 14 Boeing 747s at takeoff, according to its manufacturer. In other words, this is gonna be one hell of a fire. | Some 55 tons of propellant per second will be burned by the booster with the goal of producing 3.6 million lb of maximum thrust, equivalent to the power of 14 Boeing 747s at takeoff, according to its manufacturer.

| A successful test in March heated conditions to +32 degrees Celsius (+90 Fahrenheit), but Tuesday’s two-minute trial will see how it handles cooler temperatures of +4 degrees Celsius (+40 Fahrenheit) it may encounter on future voyages in the cold reaches of the universe. | A successful test in March heated conditions to +32 degrees Celsius (+90 Fahrenheit), but Tuesday’s two-minute trial will see how it handles cooler temperatures of +4 degrees Celsius (+40 Fahrenheit) it may encounter on future voyages in the cold reaches of the universe. |
