SpaceX's Starhopper vehicle was scheduled to conduct its test run today when it had to be canceled due to one of the engines on the hopper malfunctioning.
Starhopper is the single engine version of the SpaceX Starship and is the craft Musk and his team designed to eventually take people around the Moon and Mars. According to the team, the hopper's 150 meter test flight and landing was aborted due to one of the gines on the hopper not igniting. Elon Musk Tweeted and said "Igniters need to be inspected. We will try again tomorrow same time."
Musk then followed up with another tweet explaining the malfunction in more detail, saying "Raptor uses dual redundant torch igniters. Better long-term, but more finicky in development. Appears to be a wiring/connector issue " Another flight schedule hasn't been booked as of yet as the SpaceX team is currently evaluating what is needed to be done before a test flight can commence.
