Don't have 44 minutes to not find the info - the second link didn't say why it didn't get to fly and just provided a cgi. Perhaps you could do a one-sentence synopsis? Give the timestamp in the video? C'mon, it's you making the argument and providing Youtube rabbit-hole time sinks isn't doing that.
starts at 23:00 on the video by Common Sense Skeptic entitled [Of Rockets, Shuttles and Planes] on youtube.
Star-Raker design uses 3 types of rocket engine.
10 air breathing rocket/jet engines for takeoff and landing.
and 3 stored oxidizer liquid-fuel cryogenic rocket engines for getting into orbit. as the space shuttle did so.
with third type is the steering thrusters.
Star-Raker design has much in common with the space shuttle's aerodynamics.
with a cargo capacity of 100,000 kg more then the space shuttle's 29,000 kg.
Star-Raker's internal tanks held all propellants needed unlike the space shuttle.
largest technical challenge for Star-Raker IMO would be venting the fuel tanks without explosion.
between the modes of flight. such as starting and re-starting engine procedures.
the Star-Raker has a side-swing flip-out flight crew cabin design type nose cone.
the landing gear of Star-Raker is also retractable but must also have a set of jettisoned or drop-off super-heavy
runway takeoff gear bogies.
IMO starship's super heavy vertical design has failed to capitalize on the experience learned from the space shuttle.
levs open the possibility of horizontal Star-Raker using super heavy rocket sled takeoffs from rails beside the space-port/airport runways.
the design can also have booster rockets to assistance takeoff. with the crew cabin/nose cone acting as an escape pod if something goes wrong. So then successful the same Star-Raker landing back on earth's runways with rubber tyre's like an aircraft or space shuttle did.
Star-Raker concept was to be the super heavy space shuttle for a Space-based solar power
concept for collecting solar power in outer space. and then using microwave power transmission
to get it back to earth.
why Star-Raker sized space shuttle was no longer needed
https://en.wikipedia.org/wiki/Space-based_solar_powerThe project was cancelled with the change in administrations after the 1980 United States elections.
so the Star-Raker horizontal takeoff super heavy space shuttle design A single-stage-to-orbit (SSTO) vehicle.
was also was not continued. funding was stopped and the project cancelled
you will find Star-Raker mentioned here
