Blue Origin, the space company owned by Amazon founder Jeff Bezos, has launched a legal challenge against NASA after the federal space agency chose rival firm SpaceX to take part in its upcoming moon missions.

Blue Origin has complained about NASA's decision for months, after the agency granted SpaceX a $2.9 billion contract to develop a system that will land humans on the moon for the first time in decades. This could happen as soon as 2024.
