T-minus 3 hours and counting. NASA and SpaceX launch team members are gathering in preparation for final countdown activities, which will include fueling of the Falcon 9 rocket with kerosene and liquid oxygen propellants.

The launch team will oversee loading of high-pressure helium into the rocket, then give the "go" to pump RP-1 kerosene into the Falcon 9 at 5:41 p.m. EDT (2141 GMT). Super-cold liquid oxygen will begin flowing into the two-stage rocket at 6:16 p.m. EDT (2216 GMT).

Launching #TESS required #Falcon9 to obtain a Category 2 certification from NASA's Launch Services Program - explaining why it is launching on the last new Block 4 and not the new Block 5 which will have to go through certification for LSP and NASA Commercial Crew missions.

T-2hrs and COUNTING. Everything continues to proceed smoothly with the count at this time. #NASA #TESS #SpaceX #Falcon9

It has been a long road to launch for @NASA_TESS, the team has worked to design, assemble, test, ship the observatory over the course of the last five years. #TESS

If SpaceX is successful in recovering the Falcon 9 first stage on today's launch, the company wants to refly on the next Dragon resupply mission to the International Space Station, set for June 28. Such a move is pending NASA approval.

The @SpaceX team recently conducted a communications polls with the other organizations on the nets today. We are approaching polling of the teams for propellant loading. #Falcon9 #TESS

There are no Collision Avoidance (COLA) cutouts today, so we will launch at the open of the 30 second window occurring at 6:51 p.m. EDT (2261 UTC). COLA is a check by the Range that the rocket's trajectory isn't expected to encounter other objects in space. #Falcon9 #TESS

T-1 Hour to today's half-minute window to send #TESS on its way, driven by the precise geometry between the Cape Canaveral Launch Site & the moon to set up a flyby after three and a half phasing loops around Earth. Countdown appears to be running nominally so far.

Hazard area and flight area clearance is being verified by the Eastern Range prior to LOX load and AFTS downrange tracking stations provide a final verification of readiness as well. #Falcon9

NASA Launch Manager Omar Baez has conducted a poll and his team is ready to proceed with the liquid oxidizer (LOX) loading. LOX= the super cold (cryogenic) fluid loaded onto #Falcon9 for #TESS, which reaches with the kerosene (RP-1) in the engines to propel to space.
