1. Rockets
   Rockets are the only vehicles powerful enough to carry people and equipment into space. Since 1957, rockets have lifted hundreds of artificial satellites into orbit around Earth. These satellites take pictures of Earth's weather, gather information for scientific study, and transmit communications around the world. Rockets ... carry scientific instruments far into space to explore and study other planets. Since 1961, rockets have launched spacecraft carrying astronauts and cosmonauts into orbit around Earth. In 1969, rockets carried astronauts to the first landing on the moon.
2. Scientists
   With entries on scientists ranging from Archimedes to Stephan Jay Gould, A Dictionary of Scientists is an authoritative reference guide to the scientific luminaries of history. A Dictionary of Scientists contains over 1,300 entries covering all areas of science, from astronomy to mathematics.
3. Rockets -- Vehicles
   Scientists use liquid-propellant rockets for most space launch vehicles. Liquid-propellant rockets serve as the main engines of the space shuttle as well as Europe's Ariane rocket, Russia's Soyuz rocket, and China's Long March rocket.
4. Rockets -- Space
   Rockets that launch satellites and probes are called launch vehicles. Most of these rockets have from two to four stages. The stages lift the satellite to its proper altitude and give it enough speed -- about 17,000 miles (27,000 kilometers) per hour -- to stay in orbit. A space probe's speed must reach about 25,000 miles (40,000 kilometers) per hour to escape Earth's gravity and continue on its voyage.
5. Rockets -- Propellants
   Rockets in which the heat is supplied from a souce other than a propellant, such as solar thermal rockets, can be classed as external combustion engines. Other examples of external combustion rocket engines include most designs for nuclear powered rocket engines. Use of hydrogen as the propellant for such engines gives very high exhaust velocities (around 6-10 km/s).[41]
6. Scientists -- World
   "Lyrically, Rocket Scientists paint vivid images of other worlds — and better worlds.... allowing Rocket Scientists to preserve its roots and stretch its boundaries at the same time." - Sea of Tranquility
7. Rockets -- V-2
   Rockets remain a popular military weapon. The use of large battlefield rockets of the V-2 type has given way to guided missiles. However rockets are often used by helicopters and light aircraft for ground attack, being more powerful than machine guns, but without the recoil of a heavy cannon. In the 1950s there was a brief vogue for air-to-air rockets, ending with the AIR-2 'Genie' nuclear rocket,[36] but by the early 1960s these had largely been abandoned in favor of air-to-air missiles.
8. Rockets -- United States
   Francis Scott Key coined the phrase the rocket's red glare after the British fired Congreve rockets against the United States in the War of 1812. Congreve had used a 16-foot guidestick to help stabilize his rocket. William Hale, another British inventor, invented the stickless rocket in 1846. The U.S. army used the Hale rocket more than 100 years ago in the war with Mexico. Rockets were ... used to a limited extent in the Civil War.
9. Lana -- Lana Lane
   Lana traditionally has been Superman's romantic interest when they were teenagers in Smallville. In the Silver Age, she regularly appeared in series featuring the character’s teenaged self, Superboy. She ... often appeared as an adult in Superman series, vying with current love interest Lois Lane for his attention.
10. For the Love Of -- Charles Schulz
    The original off-Broadway soundtrack of "You're a Good Man, Charlie Brown," out of print for several years, was re-released last month. The new recording features four never-before-released tracks from the original demo tape Gesner sent to "Peanuts" creator Charles Schulz.
