Space Technology

Learn how Space Technology is advancing as more private and commerial companies and institutions are becoming involved in developing the next stage of manned space travel, orbital observation of the earth, communications and all the hardware needed to support it.

Will Mankind Make it to Mars?

The Red Planet has always been visible from Earth. It’s a tiny red speck in the sky that you can cover with your thumb, yet it remains millions of miles away. Mankind has had their eyes on Mars for quite a while — and we’re inching ever closer to landing the first crews there.

Man In Space – A Spacewalk Image Gallery

One of the most exiting activities of spaceflight have occurred when astronauts and cosmonauts left their spacecraft and floated free in space. The early spacewalks or Extra Vehicehicular Activities (EVA) were done to learn if man could function free in space. Later he built and repaired structures.

Images From Mars From NASA’s Rover Opportunity

NASA’s twin rovers, Spirit and Opportunity, were slated for a three month life. Both far exceeded that. Spirit is now dead but Opportunity continues its trek of exploration over Mars since 2004. The images it continues to return are staggering.

Introducing the Space Based Surveillance System (SBSS)

Work is currently underway to construct a space surveillance and tracking system that will keep watch over objects in orbit around the Earth. This project, known as the Space Based Surveillance System (SBSS), is designed to protect satellites from damage by space debris – or from military attack.

What is a Manned Spacecraft Better At Than an Unmanned One?

While it’s certainly rocket science, understanding the differences between what is a manned and unmanned spacecraft is easier than one might think. Breaking them down into categories such as their abilities, mission length, and objectives brings space closer to home.

Water Management for Manned Space Flight

Water recycling and reuse is extremely important aboard spaceships that must support life for long periods of time. Modern-day methods of purifying and recycling water can be used out in space. Read on to learn more about current and future spacecraft water management technology.

Using Nuclear Missiles in Space

Long since a steady facet of science fiction, the use of nuclear missiles in space has become a real possibility. During a brief period of time, nearly two dozen tests were conducted in Earth’s orbit. Since the Cold War, however, this has been relegated to a place of fear for humans in orbit.

Sounding Rockets Aid Atmospheric, Space Research

Sounding rockets are used to measure the properties of the upper atmosphere as well as to take ‘snapshots’ of phenomena in outer space. These rockets simply fly straight up, then fall back to Earth. But in doing so they give us much data on mysteries in and above the atmosphere.

All About Satellite Reaction Wheels

In science fiction’s golden era, giant spaceships were maneuvered with massive gyroscopes. Attached to the ship, when a force was applied, the precession of the gyroscope was transferred to the ship, causing it to rotate in pitch, yaw and roll. That concept has become a reality with reaction wheels.

What are the Advances in Space Technology and What’s New?

The old public view of the gains from NASA and the space program, was that “Tang” a drink used by astronauts, was the only thing that resulted from their endeavor. But as this article will show, NASA has provided many technological advances that have, in fact, impacted the public.

Passive Remote Sensing Principles

Passive remote sensing is the method of acquiring and interpreting data by means of detecting electromagnetic radiation from a source using passive sensors. We will look at the principles of passive remote sensing and how those principles are applied in today’s space technology.

Interesting Information About NASA’s Curiosity Rover

NASA’s new Mars Rover is bigger, stronger, faster, better (as the intro to the ‘Six Million Dollar Man’ went) than those now on the red planet. In fact, it will be more curious, as well. Its name is Curiosity. It is now on its way to search for signs of life.

Types of Active Remote Sensing Being Used Today

Active remote sensing has various applications in many fields. The technology is rapidly improving and enabling us to make our lives easier. We will examine what exactly active remote sensing is, the different types of active remote sensing methods and their applications.
