In 2000, Sacco and co-workers carried out zeolite crystallization of NaA (LTA) and NaX (FAU) in the reaction system Na 2O-Al 2O 3-SiO 2-H 2O-TEA on four separate space shuttle missions. It was hypothesized that this quiescent environment would promote the growth of larger single crystals by allowing crystals to grow at a longer residence time in a high-concentration nutrient field, and these crystals would have a high degree of crystalline perfection. In comparison with the conventional hydrothermal synthesis carried out on earth, these low-gravity levels in space may isolate the effects of natural convection, that affects the formation of defects, and minimize sedimentation. The low-gravity environment aboard the space shuttle (10 −3–10 −6g) can provide a unique environment for zeolite crystal growth.

At 73.214 s a second flash was seen that increased within milliseconds (at 73.327 s) to full size of explosion, see Figure XIII-27, a height of 14,000 m and a speed of Ma = 1.92. At 73.191 s a first flash, attributed to the ruptures of both tanks was observed. Full heating of this tank occurred at 60 s, and a first leak of the hydrogen tank was observed at 64.66 s, and after 73.137 s a hydrogen release occurred. One insulation at the lower end of the right-hand rocket (seen in the direction of flight) opposite to the tank of the liquid hydrogen leaked, so that within 0.678 up to 2.500 s from lift off fume drops escaped, 3 to 4 per second, and after 58.788 s flames appeared towards the hydrogen tank. In this process a careful insulation between the segments is essential to prevent a flash through. These single pieces had been transported from the factory to the starting place where they had been assembled to the rocket motor. For additional thrust there had been applied two solid propellant rocket motors (delivering over about 2 minutes 80% of the total thrust) of 45.56-m length and 3.7-m ∅, consisting of 11 pieces each. This mass is intended for consumption within 8 1/2 minutes of liftoff by three nozzles.

In the lower part was 1,450 m 3 liquid hydrogen and in the upper tank 541 m 3 liquid oxygen, in total a bit more than 790 t. The space shuttle was set on a main tank of 8.36 m diameter and 46.8 m length containing two tanks.
