Bob Cabana, a former astronaut and now Director of the Kennedy Space Center in Florida, was in the Rocket City. He also spoke to dozens of people at the US Space and Rocket Center. While he was speaking to people, he explained what all changes have taken place in the space agency over the years.

Also, he highlighted how the growth has been happening for the space agency and how the future would be. SLS development is underway in Huntsville, he said to the people.

"We want to get to Mars, that's the goal on the horizon. Well, we got a lot to learn before we can do that. We need to get out in that proving zone where we can spend months to almost a year out in space; learning what we need to know to be successful to go to Mars", explains Cabana.

When the space shuttles came back on earth and headed to Kennedy Space Center runway, two sleek jets were always flying escort beside them. Those jets were Northrop T-38 Talons. NASA keeps T-38 astronauts in order to provide training to astronauts and serve the purpose of transportation between centers.

The US Space & Rocket Center in Huntsville added one of the retired T-38s to its collection on Friday. The names of two NASA veterans, former astronaut Robert 'Bob' Cabana, and flight engineer Larry LaRose, were painted outside the cockpit. Cabana said that it was a pleasure for him to fly the T-38, but this is the advantage of being an astronaut.
