Watch on youtube.com


This is a cool video of the Space Shuttle Approach. You can hear the thrusters just before touch down and after touch down.

Not thrusters firing, they were deactivated entering the atmosphere. That sound at touchdown is the T38 chase aeroplane flying over.

It was just before touch down they can still use thrusters on approach to help slow the Space Shuttle. It sounds like a popping sound as they fire, it is the FLY BY WIRE making adjustments on approach. :plane:

That is not correct, the thrusters/RCS were not used to help slow the shuttle. They were used in the initial re-entry phase prior to the aerodynamic controls becoming effective but once the approach to landing was commenced the air brakes were used to regulate drag, the RCS was progressively deactivated as the mach number fell below specified values. I believe the aft yaw thrusters only were used throughout the reentry and actually used into the subsonic range of speeds due to a certain directional instability that was present in the shuttle, but they were most definitely not still in use by the time the final approach was commenced and the forward RCS were not used at all.

Per NASA: https://www.nasa.gov/audience/forstuden ... uttle.html

Also you can refer to the study here which investigated the use of the forward RCS to assist in control in the event of damage to the vehicle, but I don't believe this was ever actually attempted. This explains the use of the RCS in the introductory text in a bit more detail than the previous link.

Suggest you watch Scott Manley's video "How NASA Learned to Fly The Space Shuttle like a Glider."

It is FLY BY WIRE and it is 100% AUTO-PILOT. That is how the Space Shuttle is flown. :plane:

There is something extra for Thrusters that uses AIR DUCTING and that is the type of THRUSTER used. It is possible with a few additions for a Space Shuttle to take off VTOL and fly into Space. AIR DUCTING can be used for AEROSPACE FLIGHT. It also features WATER INJECTION like the Harrier. Future Space Ships will possibly be using CATALYST THRUSTERS which can take a Space Ship past light speed. FLY BY WIRE SUBMODE-LANDING uses THRUSTERS AIR DUCTING for REVERSE THRUST on the Space Shuttle.

In the near Future they will have bigger Space Shuttles which can fly VTOL instead of using Rocket engines which is the better way to go. There are new Powerplants being developed which do not require fuel and would suit a Space Ship like the Space shuttle. :plane:
