The Moon is about billion years old. Scientists think that a large asteroid hit the Earth, and the hot, melted rock thrown into space formed the Moon. The Moon is Earth's nearest neighbor and our only natural satellite. It takes 27 days for the Moon to revolve around the Earth - in fact, the Moon’s orbit around Earth inspired our calendar. In Depth: Lunar Reconnaissance Orbiter. The Lunar Reconnaissance Orbiter (LRO) was launched with the Lunar Crater Observation and Sensing Satellite (LCROSS) on the first U.S. mission to the Moon in over 10 years. Both were part of NASA’s now-canceled Lunar Precursor Robotic Program.
The Lunar Orbiter 1 robotic spacecraft, part of NASA's Lunar Orbiter program, was the first American spacecraft to orbit the was designed primarily to photograph smooth areas of the lunar surface for selection and verification of safe landing sites for the Surveyor and Apollo missions. It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact : Atlas SLV-3 Agena-D. Computing Lifetime. Once the appropriate values have been set in the Lifetime and Advanced windows, use the Compute button to start the lifetime long the Lifetime tool takes to estimate the satellite's lifetime depends primarily on how high the satellite is at epoch and on the Orbits per Calculation and Gaussian Quadratures parameters.

In this report, a particular lunar gravitational model, the Ferrari 5 x 5 model, was chosen to determine the lifetimes for km and km perilune altitude, near-circular parking orbits.
The need to analyze orbital lifetimes for a large number of initial orbital parameters was the motivation for the formulation of a simplified gravitational model from the original model.
In the sample of satellites with highly eccentric orbits considered, lifetimes were found to between 2 and 16 years. The very eccentric orbits may have perigee declines that are so rapid that it will be possible to predict in advance the location and time of satellite destruction with enough precision to enable stationing Lifetimes of lunar satellite orbits book in by: Small Satellite lunar missions • Past missions.

Over long time intervals the geomagnetic index Aphas an average value that is quite low, and is of no significance to lifetime predictions. It is only over timescales of a day or two that high geomagnetic activity can cause a significant increase in satellite drag, and then only for altitudes below about km.

Each satellite in turn would go screaming down past periapsis (closest approach to the lunar surface) only miles ( km) above the north lunar pole, but would each linger fully 8 hours of its hour orbit at 5, miles (8, km) above the horizon over the south lunar pole.
Science Requirements for precision Orbits around the Moon l Future scientific exploration of the Moon will certainly need improved knowledge of spacecraft orbital position at the Moon. l Studies of the lunar surface, its cratering history, and the lunar interior require higher resolution topography, gravity,and imaging than is presently Size: 7MB.
The low orbits of both subsatellites were to be similar ellipses, ranging from 55 to 76 miles (89 to km) above the lunar surface. Instead, something bizarre happened. The orbit of PFS-2 rapidly changed shape and distance from the Moon.
Satellite Orbits -Models, Methods, and Applications has been written as a compre hensive textbook that guides the reader through the theory and practice of satellite orbit prediction and determination. Starting from the basic principles of orbital mechanics, it covers elaborate force models as weH as precise methods of satellite tracking and their mathematical treatment.4/5(3).

Introduction  The Interstellar Boundary Explorer (IBEX) [McComas et al.,a] is a small NASA mission, demonstrating a unique high altitude (∼50 Earth radii (R E) apogee), lunar resonance orbit for the first orbit, and other lunar resonance orbits described here, would provide excellent locations for a variety of cost‐effective and very long‐term space weather Cited by: Books on Astronautics, Rocketry, Spacecraft, and Space Technology Spacecraft Design and Space Systems Selected Spacecraft and Systems Global Positioning System GPS and GNSS Orbital Mechanics and Satellite Orbits Rocket Dynamics Solar System Dynamics Spacecraft Dynamics, Spacecraft ADC and GNC Spacecraft and Rocket Propulsion.
By synchronizing the satellite's orbital period to integer fractions of the Moon's sidereal period, P M = days (e.g., P M /2 = days, P M /3 = days), and phasing apogee to stay away from the Moon, very long term stability can be achieved. Our analysis indicates orbital stability for well over a decade, and these IBEX‐like orbits Cited by: (The Observatory, ) "Satellite Orbits: Models, Methods, and Application would be a valuable addition to the library of any engineer or scientist interested in the Cited by: This was done by determining the angle made between the surface to satellite vector and the vector normal to the B.
