What: Orbital Sciences
So what: This is two strikes for Orbital, which suffered a similar failure in 2009 and considered the problem fixed. Two of the company's last five launches have been failures.
Now what: With the retirement of the space shuttles, Orbital was expected to win contracts to deliver cargo to the International Space Station. A batting average of .600 is a big disappointment in this business. Failing twice for the same reason raises a red flag that jeopardizes Orbital's revenue and earnings potential.
