		<description><![CDATA[Nuclear Thermal
Radiation created by nuclear technologies is dangerous to both humans and their machines. Any use of nuclear propulsion technology would have to be accompanied by the use of extensive shielding and &#8220;hardening.&#8221;
The potential advantages of nuclear propulsion over chemical methods are staggering. The energy that is available from nuclear reactions (fission, fusion, and matter-antimatter [...]]]></description>

		<description><![CDATA[Gravity-Assisted
In the early 1960s, a graduate student named Michael Minovitch working at JPL developed a way to use a planet&#8217;s gravitation as a method of propulsion. Gravity-assisted maneuvers work by transferring angular momentum from an orbiting planet to a passing spacecraft. A spacecraft&#8217;s trajectory is adjusted so that it will make a fairly close fly-by [...]]]></description>

Advanced Chemical Propulsion
Since we have already developed many different types of chemically-fueled propulsion systems, one might wonder why we need to advance these technologies. Historically, there has been a demand for improvements in many areas, such as safety, reduced mass, and of course increased specific impulse (Isp).
Modern chemical propulsion systems utilize from one to three [...]]]></description>

The US space agency has described the MoonLITE mission to send a small probe to the Moon in 2013 as &#8220;inspirational&#8221;.
The unmanned project involves the craft firing 4m-long darts called penetrators onto the lunar terrain.
The devices would enable scientists to scratch beneath the surface of the Moon and assess geological activity.

Electric propulsion works by using electrical energy to accelerate a propellant to much higher velocities than is possible using chemical reactions. The most common propellant used in ion engines is xenon.
Early experimental ion engines used mercury and caesium, but they proved hard to work with. At room temperature, mercury is liquid and caesium [...]]]></description>

Solid-fuel rocket engines were the first engines created by man. They were invented by the Chinese in the 13th century and have been widely used since then. The &#8220;rocket&#8217;s red glare&#8221; in the American National Anthem, which was written in the early 1800&#8217;s, refers to the small solid-fuel rockets that were used to deliver [...]]]></description>

Interplanetary Solar Sails
A solar sail is a spacecraft that has an immense, lightweight mirror attached to it. It derives its propulsion by being pushed by light reflecting off of the mirror, instead of traditional rocket engines. The light used could be supplied by sunlight or lasers placed in orbit. Sunlight exerts a very gentle [...]]]></description>
