Due to her eccentric / airheaded / yuppie nature, Delia is not easily frightened, unlike her husband.

Due to the series ' early cancellation, very little attention was given to Simmons ' character, but she differed from her predecessor in that she was not portrayed as an eccentric recluse, but rather as a high-spirited passionate woman with a strong devotion to her family.

Due to weight issues such as shielding, many nuclear propulsion systems are unable to lift their own weight, and hence are unsuitable for launching to orbit.

Due to a flaw in the computer chip which resulted in degradation of the chip during the voyage to Mars, the retro-rockets designed to slow the craft into Mars orbit did not fire, and Mars 4 flew by the planet at a range of 2200 km.

Due to the relationship between an orbiting object's beta angle ( in this case, the ISS ) and the percent of its orbit that is spent in sunlight, solar power generation and thermal control are affected by that beta angle.

Due to the reversibility of orbits, Hohmann transfer orbits also work to bring a spacecraft from a higher orbit into a lower one ; in this case, the spacecraft's engine is fired in the opposite direction to its current path, decelerating the spacecraft and causing it to drop into the lower-energy elliptical transfer orbit.

Due to the inherent long-term instability of orbits in this region, even centaurs such as and, which do not currently cross the orbit of any planet, are in gradually changing orbits that will be perturbed until they start to cross the orbit of one or more of the giant planets.

Due to the amount of time needed to make the changes, and the limited time Salyut 3 had left in orbit due to orbital decay, the next planned mission to the station was cancelled.

Due to their lower orbit they were gaining on Gemini 7 and were behind.

Due to the eccentricity of Jupiter's orbit the side-slightly differs from the two other sides.

Due to this as much as one quarter of the Trojans cannot intersect with the Hildas, and at all times a great deal of other Trojans are located outside Jupiter's orbit.

Due to inaccuracies in the asteroid's computed orbit it was subsequently lost and not recovered until 2000 by Jeffrey Larsen using data from the Spacewatch asteroid survey project.

Due to atmospheric drag, the lowest altitude at which an object in a circular orbit can complete at least one full revolution without propulsion is approximately 150 km ( 93 mi ), while an object can maintain an elliptical orbit with perigee as low as 129 km ( 80 mi ) with propulsion.

Due to only a few observations to date, its orbit is still relatively loosely constrained.

Due to a programming error affecting the Centaur upper stage of its carrier rocket, it was placed into a lower orbit than had been planned, and it could not be raised into its operational orbit.

Due to a higher than planned orbit that carried the spacecraft into the detector-jamming radiation of the Van Allen belt, and an early failure of the on-board tape recorder, only 141 hours of useful observing time could be culled from about 7 months during which the instrument operated.

Due to lower than expected performance, the payload falls short of its intended orbit.
