GSFC stands for Goddard Space Flight Center.
The Tracking Data Relay Satellite – K, TDRS – K is going to launch on January 30, Universal Time. It will be January 29 at Cape Canaveral, Florida. There’s a 40 minute window to launch her to get her into the right orbit. TDRS -K is the first grand daughter to go into orbit.
TDRS is a communications satellite for NASA. The first generation started orbiting the Earth in 1983. It will be retired completely in 2015.
There is a second generation up there as well.
The TDRS program is continuous and gets more sophisticated with each generation. There is more than one satellite in generations 1 and 2. This one is the first of generation 3 and 2 others are planned to join her.
Information sent from NASA spacecraft like Voyager2, the Mars Exploration Rover, Opportunity And the Mars Science Laboratory, Curiosity, travel to the communication satellites and then it is sent to receivers on Earth. That is the really simple version of what happens. It’s a lot more complicated that this, but at that point, I’d be in over my head.
The pictures in the lab of TDRS -K are from Boeing, the maker of the satellite. The others are from NASA.
This is a picture of the first generation communications satellite.
This is a picture of generation 2.
Here are two diagrams to give an idea of where the satellites are, above the Earth.

Here are two pictures of the antenna, in the lab.

These are two pictures of TDRS – K folded, in the lab. The first is during a fitness test.

The Atlas V 401, will put the satellite into orbit.
This is a diagram of the Atlas V from Lockheed Martin.
Lockheed Martin and Boeing are together in a company called United Launch Alliance. At first, when I saw the United name on photos, I was confused.
These are two pictures of the Atlas V 402 rocket first stage being transported and then being into the launch frame at Cape Canaveral. The first stage lifts the payload off the ground and into the Earth’s atmosphere.

This is the second stage of Atlas V, called Centaur, being put into place in the frame. This powers the payload in the right direction to go into orbit.
The next three pictures are of the TDRS – K inside the capsule. The capsule is closed and placed on top of the second stage, in the frame.


The last two pictures ore artists drawings of TDRS – K above the Earth. After the launch, I will post pictures of the launch. The grand daughter will be in orbit.
