Hyper-sonic Engine
There is a new invention that can get a astronaut to the moon in half the time a normal space ship can. It is called the hyper-sonic engine. The hyper-sonic engine can travel 4500 miles per hour. The hyper-sonic engine is 32 million dollars for one of them. The US have already bought 2 of these engines for the possible trip the mars. This ship will propel the Skylon orbiter so it can go up very easily. This machine is a revolutionary piece of equipment and they are still improving it today.
