“The moon moves in an orbit around the Earth.”

“The concern is that the gravitational tug of Jupiter could alter the orbit of the spacecraft and cause it to hit Europa or another moon.”

“In a different orbit altogether are forthcoming books by two authors also associated with the pop business.”

“The descent profile provides the important link between measurements made by instruments on the Huygens probe and the Cassini orbiter.”

“In other instances, an orbiter or a spacecraft on a flyby mission may have already taken photographs of a moon or planet.”

“But, once again, the orbiter failed to pick up a signal from the lander, ESA officials announced.”

“At this time, the maximum number of electron orbitals or electron shells for any element is seven.”

“The triple bond is composed of one sigma bond from overlap of sp hybrid orbitals, and two pi bonds, from overlap of two sets of p orbitals.”

“As a result, the orbitals become deformed, weakening the existing bond between molecules.”

“The program would start with lunar orbiters, which would be followed by landers and rovers, and eventually sample return missions.”

“This smart software can be used on all kinds of spacecraft, including orbiters, landers and rovers.”

“Martian orbiters can use aerobraking to reduce the amount of propellant they need.”
