Today, space technology is used as an excellent instrument for Earth observation applications. Data is collected using satellites and other available platforms for remote sensing. Remote sensing data collection detects a wide range of electromagnetic energy which is emitting, transmitting, or reflecting from the Earth's surface. Appropriate detection systems are needed to implement further data processing. Space technology has been found to be a successful application for studying climate change, as current and past data can be dynamically compared.
In January 2004, President George W. Bush announced new elements of the national space policy by issuing
the Vision for Space Exploration (VSE). The new policy set out goals for NASA, including that of exploring the
“solar system and beyond” with human and robotic missions—specifically, to “extend human presence across the
solar system, starting with a human return to the Moon by the year 2020.” In the year that followed, NASA created
the Exploration Systems Mission Directorate (ESMD) as the primary agent for the development of the exploration
Unit D: Space and technology includes Earth and Space (What is the Sun? What causes day and night? What causes seasons to change? What can you see in the night sky? Why does the Moon seem to change? What is the solar system?); Technology in Our World (What is technology? How does technology help us?...).
(BQ) Looking back at the creation and accelerated development of the early U.S. and former-Soviet "space race," ebook Scientific American: Great Moments in Space Exploration profiles the intrepid American astronauts and Russian cosmonauts who boldly ventured where none had gone before. It also offers current facts on the most recent developments in space technology, including those involving international cooperation among countries.
Many of the images reveal inaccessible places that few have seen and record animal behavior that has never been filmed or photographed before. With the help of this highly advanced technology and the world's premier wildlife photographers, the book takes us on a spectacular journey from the world's greatest rivers and impressive gorges, to its mightiest mountains, hidden caves and caverns, and vast deserts.
A seeder should place seed in an environment for reliable germination. The main objective
of sowing is to put seeds at a desired depth and spacing within the row. Uniform seed
distribution within the soil result in better germination and emergence and increase yield by
minimizing competition between plants for available light, water, and nutrients. A number
of factors affect seed distribution in soil. Seed metering system, seed delivery tube, furrow
opener design, physical attributes of seed and soil conditions all play a part in determining
The development and launch of the fi rst artifi cial satellite Sputnik more than fi ve decades
ago, propelled both the scientifi c and engineering communities to new heights
as they worked together to develop novel solutions to the challenges of spacecraft system
Inquiring on the sky (i.e., the Universe) has been present as affair of concern of the
human kind since the early days of the first hominids like homo floresiensis and late
homo sapiens. Fascination of sky watchers on a starry night, with its planets and the
Moon, still today invites the best human minds to struggle for unveiling its secrets.
To extending farther out the reach of our eyes, the telescope was introduced to
astronomy in 1609 by Galileo Galilei.
From the interior of the Sun, to the upper atmosphere and near-space environment of Earth, and
outward to a region far beyond Pluto where the Sun’s influence wanes, advances during the past decade in
space physics and solar physics—the disciplines NASA refers to as heliophysics—have yielded
spectacular insights into the phenomena that affect our home in space. This report, from the National
Research Council’s (NRC’s) Committee for a Decadal Strategy in Solar and Space Physics, is the second
NRC decadal survey in heliophysics.
dipole antenna is a radio antenna that can be made of a simple wire, with a center-fed
driven element. It consists of two metal conductors of rod or wire, oriented parallel and
collinear with each other (in line with each other), with a small space between them. The
radio frequency voltage is applied to the antenna at the center, between the two
conductors. These antennas are the simplest practical antennas from a theoretical point of
Wireless e-business allows people to communicate and transact in business via
wireless technology, without physical connectivity, such as wires or cabling.
Wireless e-business uses many devices, including mobile phones, pagers, palmpowered
personal computers (PCs), pocket PCs, laptop computers, and other mobile
devices or devices connected to the wireless networks
The Sun to the Earth—and Beyond: A Decadal Research Strategy in
Solar and Space Physics is the product of an 18-month effort that began in
December 2000, when the National Research Council (NRC) approved a
study to assess the current status and future directions of U.S. ground- and
space-based programs in solar and space physics research. The NRC’s
Space Studies Board and its Committee on Solar and Space Physics organized
the study, which was carried out by five ad hoc study panels and the
15-member Solar and Space Physics Survey Committee, chaired by Louis J.
In 2003, the National Research Council (NRC) published the first decadal strategy for solar and
space physics: The Sun to the Earth—and Beyond: A Decadal Research Strategy in Solar and Space
Physics.1 That report included a recommended suite of NASA missions that were ordered by priority,
presented in an appropriate sequence, and selected to fit within the expected resource profile for the next
The Space Handbook, first published in 1958, was designed to serve as a basic guide on the uses and characteristics of space systems, including astronautics and its applications, technology in the space environment, rocket vehicles, propulsion systems, propellants, internal power sources, structures and materials
