	SignOnSanDiego Science News -- Rocket launch with NASA, Orbital Sciences payload goes awry, satellites probably lost
		Although the launch came in the aftermath of last week's terrorist attack on the United States, sabotage was not under consideration.
		The rocket also carried the National Aeronautics and Space Administration's QuikTOMS satellite, one of a series of NASA instruments that have kept tabs on ozone levels in the upper atmosphere since 1978.
		The oddest bedfellow in the rocket's mixed payload was provided by the Celestis Corp. The Houston company sells, at $5,300 a pop, the opportunity to launch small portions of cremated remains into orbit.

		The launch of the MER-B spacecraft will be the second use of a core Delta II "Heavy" launch vehicle and the first use of a Delta II "Heavy" launch vehicle with an upper stage.
		The amount of energy it took to launch each of the two Mars Exploration Rovers was slightly different because the distances between Earth, Mars and the Sun changed in between the two rover launch periods.
		Technologies associated with these propulsion maneuvers often involve better ways of measuring where the spacecraft is in space so that engineers can determine the appropriate burns needed to tweak the spacecraft's trajectory.

	The Evolution of Rockets
		The military's rockets were larger and more ambitious, and the A2 which flew in 1934 developed a thrust of 16000 newton.
		The usual payload of the V-2 rocket was one ton (1000 kg), and with that a height of about 100 km was possible.
		The launch mass of the V-2 was about 75% fuel and 25% rocket, but as high as that may seem, it is not nearly good enough for spaceflight.

	Space Future - How Much New Technology is Required for Future Reusable Launch Systems?
		It is generally assumed that substantial improvements of technology are required for the next generation of (reusable) launch vehicles.
		The tremendous difference of potential launch vehicle system concepts and the required new technologies do not only have a dramatic effect on development cost and time schedule but also on the later operability (risk and reliability) as well as on the finally achievable reduction of transportation cost into space.
		It is recognized generally that the related technology must be available at the start of a dedicated vehicle development programme in order to reduce the technical and financial risk.

	USATODAY.com - Liftoff propels Japan back into space race after 2003 failure (Site not responding. Last check: 2007-10-01)
		The 174-foot-tall rocket, with the word "Nippon," or Japan, emblazoned on its side, lifted off into a cloudy sky just before sunset from the sprawling space center on this remote southern island.
		Japan's space agency, JAXA, was counting on a successful launch to help revive the reputation of the H-2A, which serves as the centerpiece of this country's space program, and to demonstrate that Japan remains a viable contender in an increasingly heated Asian space race with China.
		All H-2A launches had been put on hold following a humiliating failure in November 2003, when a booster failed to detach and controllers had to detonate the rocket and its payload of two spy satellites just minutes after liftoff.

	Spaceflight :Solid Propellants for Missiles and Rockets
		In fact, the rockets that Francis Scott Key observed during the War of 1812, called Congreve rockets after their English inventor William Congreve, and which are mentioned in the U.S. national anthem, were virtually identical to those fired by the Chinese eight centuries before.
		Solids were used for many military applications, such as short-range rockets, but they were not used for any long-range applications, and certainly not for spaceflight due to their comparative lack of power.
		Soviet rocket designers produced better liquid propellants than their early ones that could be stored inside the missile for long periods of time, but they lagged far behind the United States in solid propellant technology.

	AeroWorldNet(tm) - What's Wrong With the Launch Industry? [May 10, 1999]
		What we're seeing with the latest series of rocket launch failures is the working out of "the kinks" in a new generation of rocket launch technology, Caceres told AWN.
		Successful launches receive their share of attention, but a rocket blowing up in fireball over the night sky or the loss of a multi-million dollar satellite payload, especially if it was built at the taxpayers' expense, is going to lead newscasts all over the world.
		These new vehicles, equipped with new generation technology, don't undergo the same length of testing performed on launch vehicles of the past in order to speed their introduction into the marketplace, Caceres said.
