Jeff Bezos’ Blue Origin has called off the launch of its New Glenn rocket from Florida at the last minute after a “few anomalies” were found during mission countdown.

New Glenn is capable of carrying 50 tons (45 metric tons) of payload to low Earth orbit (LEO). SpaceX's Falcon Heavy rocket, which also features reusable first stage boosters, can lift around 70 tons (64 metric tons) to LEO.

Blue Origin scrubbed a planned launch of its New Shepard rocket Tuesday due to persistent cloud cover at the west Texas launch site. In a post on social media, the company said an additional issue with the rocket’s avionics was discovered during the 90-minute-plus launch hold.
