Past and Future By Paul D. Spudis, Lunar and Planetary Institute The moon has held our imaginations for millennia, yet it is only in modern times that we have visited this body, first with robotic machines and then with astronauts.
Exploration of the moon has taught us much about the evolution of the solar system and ourselves. But it took space-age exploration to show us how the moon is connected to human existence on a very fundamental level.
The Space Age arrives: Robots to the moon Exploration at its greatest - Geologist-astronaut Jack Schmitt standing next to a huge, split boulder during the Apollo 17 exploration of the Taurus-Littrow landing site in December Schmitt and Gene Cernan were the last two astronauts to explore the moon in the 20th century.
With the shocking launch of Sputnik 1 in Octoberthe moon changed from a distant silver disk in the sky to a real place, a probable destination for probes and people. The Soviets struck first, flying Luna 1 by the moon in January They followed this success with a number of other robotic probes, culminating later the same year with Luna 3, which photographed the far Nasa past present and future essay of the moon, never visible from Earth.
From these early, poor quality images, we discovered that the far side has surprisingly little of the dark, smooth mare plains that cover about a third of the near side.
Other surprises would soon follow. Kennedy committed the United States to landing a man on the moon by the end of the decade. The Apollo program greatly accelerated interest in exploring the moon.
To ensure that human crews could safely land and depart from the lunar surface, it was important to understand its environment, surface and processes. At the same time, the robotic precursors would collect valuable information, constituting the first scientific exploration of another planetary body.
Robotic precursors - From top to bottom the Ranger, Surveyor and Lunar Orbiter spacecraft and the images they provided of the lunar surface. These probes were designed to photograph the lunar surface at increasing levels of detail before crashing into the surface.
After several heartbreaking failures, Ranger 7 succeeded in sending back detailed television pictures of Mare Nubium Sea of Clouds in July From the Ranger probes, we discovered that craters, those strange holes that pepper the lunar surface, range down in size to the very limits of resolution.
Micrometeorite bombardment has ground up the surface rocks, creating a fine powder called regolith. Two more Ranger spacecraft flew to the moon, culminating with the Live From the Moon television images from Ranger 9, careening into the spectacular lunar crater Alphonsus.
It found the surface to be powdery dirt strewn with a few rocks, but strong enough to support the weight of a landed spacecraft.
In Maythe United States followed with the landing of the complex robotic spacecraft, Surveyor 1. It sent television pictures back to Earth, showing the surface and its physical properties in detail.

In the National Aeronautics and Space Act was signed allowing for NASA to be formed.

Lunar Exploration: Past and Future. past or present. Small bits of white rock were found in the soil, blasted to the site from distant highlands. In the s, two small robotic missions were sent to the moon. For 71 days in , the joint NASA-Strategic Defense Initiative Organization Clementine mission orbited the moon, testing.
Later Surveyor missions five in allcollected physical data on soil properties, including its chemical composition. Analysis of the lunar surface showed that the dark maria had a composition similar to terrestrial basalt, a dark iron-rich lava, while the highlands near the very fresh rayed crater Tycho were lighter in color and strangely enriched in aluminum.
The final robotic missions mapped the entire moon from orbit for the first time and obtained extremely high resolution pictures of potential landing sites, certifying their safety for the Apollo missions to follow. Lunar Orbiter series conducted five mapping missions, whereby boulders as small as a couple of meters could be seen.
From these robotic missions, we learned that the moon was cratered and pitted at all scales.

NASA Invests in Visionary Technology NASA is about to go on a journey to study the center of Mars.
The surface was powdery dust but strong enough to support the weight of people and machines. The moon had no global magnetic field or atmosphere and was made up of common rock types, similar to those found on Earth.
Now the stage was set for the next giant leap in understanding lunar and planetary history.DISCUSSION OF DNS: PAST, PRESENT, AND FUTURE Ronald D. Joslin NASA Langley Research Center, Hampton, VA U.S.A.

Statements in the future tense do not obey the same logic as present-tense statements: they do not have to be either true or false. Logicians following Aristotle have allowed the possibility of a third truth value, ‘undetermined’ or ‘undecided’, in addition to ‘true’ and ‘false’.
