Galileo was one of the first spacecraft to be equipped with a CCD camera. Light was collected by the primary mirror and directed to a smaller secondary mirror that channeled it through a hole in the center of the primary mirror and onto the CCD. The CCD sensor was shielded from radiationa particular problem within the harsh Jovian magnetosphere. An eight-position filter wheel was used to obtain images at specific wavelengths.
See shopping cart for details. During 30 years and missions, the U. It was a staggering record of success.
Unfortunately, it was accompanied by a tragic record of failure, with two accidents claiming the lives of 14 astronauts as well as other incidents claiming several ground personnel. We cannot print enough money to make it totally risk-free. Because it flew for 30 years, most people alive today do not remember a time when the space shuttle was not in the news.
The public was enthralled, the politicians somewhat less, and the armchair critics even less so. The space shuttle was meant as a stepping-stone to broader exploration. But the funding and political will never materialized, leaving the vehicle with little meaningful work for most of its flight campaign.
Only near the end was it able to demonstrate its intended purpose, building a space station. Even that, when finished, was only a shell of what had been envisioned when the space shuttle was approved.
Unfortunately, having found its stride as the primary support vehicle for the International Space Station, the White House canceled the program, leaving the United States without the ability to launch people to orbit. All of this has left an uncertain legacy for one of the most visible engineering achievements of the 20th Century.
This book is not meant to establish that legacy, but to thoroughly document the development, technology, and, to a lesser extent, the flight campaign. We will leave it to future historians to determine the ultimate worthiness of the program.
What we can say for certain, though, is that it was one hell of a ride.Buy Mars: Uncovering the Secrets of the Red Planet on attheheels.com FREE SHIPPING on qualified orders.
U.S. spacecraft Galileo making a flyby of Jupiter's moon Io, in an artist's rendering.
At the stage of the mission being depicted, the atmospheric probe has already been deployed; its former point of attachment is the circular structure at Galileo's nearer end, along the main axis. Solar system exploration.
From the start of space activity, scientists recognized that spacecraft could gather scientifically valuable data about the various planets, moons, and smaller bodies in the solar attheheels.com the United States and the U.S.S.R.
attempted to send robotic missions to the Moon in the late s. The first four U.S. Pioneer spacecraft. Space exploration is the discovery and exploration of celestial structures in outer space by means of evolving and growing space attheheels.com the study of space is carried out mainly by astronomers with telescopes, the physical exploration of space is conducted both by unmanned robotic space probes and human spaceflight..
While the observation of objects in space. This is a partial list of past, present, and future planetary and solar missions; for a complete account, please see the Space Exploration Chronology. Space exploration is becoming increasingly internationalized; as a result, the national designations listed here are not completely representative of.
