Space shuttle Discovery has two of its three main engines in place and technicians will install the third one today as work continues at NASA’s Kennedy Space Center in Florida to ready the spacecraft for the STS-133 mission. The engines were removed last week so a faulty turbopump on the center engine could be replaced. The engine work is not the only processing under way on Discovery today. Technicians are also testing the Orbiter Boom Sensor System that astronauts will use to inspect the heat shield after the shuttle reaches orbit.
At NASA’s Johnson Space Center, the STS-133 crew will conducts its first integrated ascent simulation today.
