The height of the spacecraft on the lunar surface is about 10 feet. The launch
weight of Surveyor I was about 2193 pounds including the retroengine and the
propellants for the liquid system. Before landing, the retroengine separated and
was ...

Scientific results of the Viking Project
Near the spacecraft (Figure la), retroengine exhausts have eroded the surface,
dislodged small rocks, produced fillets of debris on the sides of rocks facing
retroengine 2, and propelled small grains and fragments that produced small
craters ...

In orbit each Mariner will weigh 1200 lbs, but each carries to Mars, as well, about
1000 lbs . of fuel for the 14-minute retroengine burn needed to slow it to the
requisite orbital speed. The Mariner aiming zone, the tightest the rocket
engineers ...

As the spacecraft's trajectory is bent by the planet's gravity, the command
sequence aboard the spacecraft fires its retroengine(s) at the proper moment and
for the proper duration. Once this retroburn (or retrofiring) has been completed ...
Gabriel's retroengine rose in pitch, then abruptly shut off, and his capsule banged
into the surface of the icy planet. The shell of the capsule split vertically and
spread the doors wide, allowing the weak pre-dawn glow to enter. Gabriel quickly

Second, Wirth's code, based on the inherited RetroEngine, assumes that all
conversions are effected by the winner. This is not so: the loser is sometimes
forced to convert to loss, e.g., {wKelQblRfl/bKal}, in which case Wirth's depth is
too great ...
