Boeing is facing another setback in its Starliner launch. The aerospace company's Starliner space capsule is being sent back to the factory to fix faulty valves, which have delayed the past several launch attempts. The company says it's working with NASA to determine a new launch date when the spacecraft is ready. If that doesn't happen soon, the Starliner could lose its spot to an incoming Space-X dragon cargo ship, which is scheduled to launch at the end of this month.

Elon Musk announced over the weekend that Space-X's starship rocket could be ready for its first flight into space in the next few weeks. The Tesla CEO and Space-X founder said in a tweet that the only thing the rocket is waiting for now is regulatory approval. Space-X successfully landed its prototype of the starship back in May - the first successful landing following four that ended up exploding. The complete starship stands nearly 400 feet tall.
