Science (New York, N.Y.)
|September 2, 1966
Summary
The first U.S. lunar satellite is providing new insights into the moon's gravitational field. Early data suggest a pear-shaped lunar component, with scientific interest in its gravitational properties.
Area of Science:
- Lunar science
- Gravitational physics
Background:
- Understanding the Moon's gravitational field is crucial for lunar exploration and orbital dynamics.
- Previous models of lunar gravity may not fully capture its complexities.
Purpose of the Study:
- To analyze initial data from the first U.S. lunar satellite.
- To gain new information about the Moon's gravitational field.
Main Methods:
- Orbital tracking of the U.S. lunar satellite.
- Analysis of telemetry data regarding the spacecraft's trajectory and gravitational interactions.
Main Results:
- The satellite has already yielded significant new data on the Moon's gravity within days of orbit.
- Preliminary findings indicate a substantial pear-shaped component to the Moon.
- The spacecraft is projected to complete its photographic mission before any potential lunar impact, estimated in approximately 8 months.
Conclusions:
- The Moon's gravitational field possesses unique characteristics of significant scientific interest.
- The observed pear-shaped component warrants further investigation.
- The satellite's mission is expected to conclude successfully before its eventual lunar impact.

01:20Rocket Propulsion in Gravitational Field - I
Rockets range in size from small fireworks that ordinary people use to the enormous Saturn V that once propelled massive payloads toward the Moon. The propulsion of all rockets, jet engines, deflating balloons, and even squids and octopuses are explained by the same physical principle: Newton's third law of motion. The matter is forcefully ejected from a system, producing an equal and opposite reaction on what remains.
The motion of a rocket in space changes its velocity (and hence its...

01:27Gravity between Spherical Bodies
Newton's law of gravitation describes the gravitational force between any two point masses. However, for extended spherical objects like the Earth, the Moon, and other planets, the law holds with an assumption that masses of spherical objects are concentrated at their respective centers.
This assumption can be proved easily by showing that the expression for gravitational potential energy between a hollow sphere of mass (M) and a point mass (m) is the same as it would be for a pair of extended...

01:24Acceleration due to Gravity on Other Planets
The gravitational acceleration of an object near the Earth's surface is called the acceleration due to gravity. It can be measured by conducting simple experiments on Earth. However, such an experiment is impossible to conduct on the surface of other planets.
Astronomical observations are thus used to measure the acceleration due to gravity on other planets. This can be determined by observing the effect of a planet's gravity on objects close to it. The crucial factor that helps in this...

01:06Tidal Forces
The origin of Earth's ocean tides has been a subject of continuous investigation for over 2000 years. However, the work of Newton is considered to be the beginning of the proper understanding of the phenomenon. Ocean tides are the result of gravitational tidal forces. These same tidal forces are present in any astronomical body; they are responsible for the internal heat that creates the volcanic activity on Io, one of Jupiter's moons, and the breakup of stars that get too close to black holes.
01:09Radiation Pressure: Problem Solving
The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force per...

01:16Gravitation
In the years before Newton, a general belief prevailed that different laws governed objects in the sky than objects on Earth. When Kepler wrote down the three laws of planetary motion, explaining in detail the geometrical properties of the planetary orbits around the Sun, there was no immediate idea to discern their connection with more fundamental laws. It was Isaac Newton who, in 1665–66, figured out the connection between planetary motion, the motion of the moon around the Earth, and the...
