SpaceX Starship could be launched on its first 'Test Hop' this week, Musk says

SpaceX CEO Elon Musk, in a series of tweets, confirmed that the space company will begin testing the early prototype of it Mars hopper Starship starting the week of 18 March. This is a big, important milestone for the company towards taking humans aboard the Starship into Earth's orbit — and eventually, Mars.The "hopper" will only have a single Raptor engine unlike the final version, which will be powered by three. The engine was put to the test in February and passed with flying colours.Currently far from space-worthy, the prototype will allow the company to test its ability to "hop" from a spaceport and land back on the ground using propulsion.During the test, Starship won’t enter orbit. The preliminary, low altitude test flights will help monitor performance and prepare the spacecraft for future journeys as long as a trip to Mars.Musk confirmed that SpaceX was indeed close to beginning tests and that integration work was yet to be done on the test vehicle and its Raptor rocket engine. He said the first hops would lift off, but only "barely."[caption id="attachment_6287051" align="alignnone" width="1024"] Engineers working on Starship as it gets nearly ready for its first hops.
