During testing Saturday, the SpaceX Crew Dragon, designed to ferry humans between Earth and the International Space Station (ISS), suffered "an anomaly".
According to reports by Florida Today, orange plumes of smoke were seen billowing for miles from Cape Canaveral, Florida, where the testing was taking place.
"Earlier today, SpaceX conducted a series of engine tests on a Crew Dragon test vehicle on our test stand at Landing Zone 1 in Cape Canaveral, Florida.
The initial tests completed successfully but the final test resulted in an anomaly on the test stand.
Ensuring that our systems meet rigorous safety standards and detecting anomalies like this prior to flight are the main reasons why we test.
Our teams are investigating and working closely with our NASA partners" according to a SpaceX spokesperson.
