The launch was slated to take place from Cape Canaveral Air Force Station on Monday evening, but was pushed back so that SpaceX could “conduct additional GNC analysis.”

The launch, which is now scheduled for Wednesday, will feature a brand new Falcon 9, as opposed to the used (sorry, “flight proven”) rockets that the company sometimes uses after recovering and refurbishing them. CAPE CANAVERAL, Fla. (Reuters) - SpaceX postponed a planned launch on Monday of a Falcon 9 rocket carrying NASA's latest planet-hunting satellite for 48 hours, citing problems with a guidance-navigation control system, launch team officials said.

The launch had been scheduled for Monday, but was postponed to conduct additional guidance, navigation and control systems analysis.
NASA's TESS exoplanet space telescope, whose launch was initially delayed, is successfully launched from Cape Canaveral Air Force Station by SpaceX on a Falcon 9 rocket. The first stage of the rocket successfully landed on SpaceX's autonomous spaceport drone ship in the Atlantic Ocean.
