<title><![CDATA[Press Briefing Coming Up, Blog Concludes]]></title>
<description><![CDATA[The launch team for Glory is working through its launch contingency plan, including collecting data from the launch. A news briefing will be held in about 2 1/2 hours to talk about the launch. Today's launch blog is concluding now, but the briefing will be broadcast on NASA TV and coverage also will continue on NASA's Glory web site.]]></description>

<description><![CDATA[The Glory spacecraft is now running on its own power, using onboard batteries. After launch, the spacecraft will unfold a pair of solar arrays that give the satellite the impression of having wings. The solar arrays will convert sunlight into electricity during the mission's three- to five-year mission.]]></description>

<title><![CDATA[P-PODs Hitch a Ride on Taurus XL]]></title>
<description><![CDATA[A small aluminum container has been bolted to the fourth stage of the Taurus XL rocket to give three university teams a chance to fly tiny satellite experiments into orbit. The rectangular box looks like an aluminum shoebox and contains a trio of 4-inch cube satellites, called CubeSats. Ten seconds after separating the Glory spacecraft, the Taurus stage will eject the three satellites from the container and they will relay their data to the student science teams on Earth. One of the satellites will take measurements of the Van Allen radiation belts, another is to test a high-speed space communications systems and a third is a platform for a camera and radio.]]></description>

<title><![CDATA[The Payload Fairing and What It Means for Glory]]></title>
<description><![CDATA[This mission marks the first flight of the Taurus XL rocket since Feb. 24, 2009, when one was used to launch the Orbiting Carbon Observatory, or OCO. The reason for the delay is that the OCO never reached orbit because the payload fairing that protected it during launch did not separate and fall away from the top of the rocket. Engineers and designers spent months poring over the telemetry data from that mission and testing all the components to track down a suspected culprit. After that, they redesigned some of the critical parts of the fairing separation system to make them more reliable. <br/><br/>The 63-inch-diameter fairing that is secured around the Glory spacecraft this morning has received a lot of attention so far and will get careful looks as the rocket heads into orbit today.]]></description>

<title><![CDATA[20 Minutes to Launch]]></title>
<description><![CDATA[At this point in the countdown, the launch team has been moving systems to internal power, meaning the systems will run from batteries onboard the rocket instead of from power sources on the ground. The Glory spacecraft itself also carries batteries to provide power until it is able to unfold its twin solar arrays after it gets into orbit. The Glory spacecraft is not switched to internal power until T-11:30, though.]]></description>

<title><![CDATA[Aerosol Instrument Crucial for Researchers]]></title>
<description><![CDATA[The Glory spacecraft carries an instrument designed to focus on aerosols in unprecedented detail. A primary function of the instrument is to determine how much of the aerosols in Earth's atmosphere are produced by human activity such as burning plant material and how much is a byproduct of natural occurrences such as volcano eruptions. Aerosols are tiny particles of materials that can float high into the stratosphere and be carried around the globe. Some of the particles have a cooling effect on the Earth, while others enhance warming, studies suggest. Glory's scientists hope the spacecraft will complete the picture of what the aerosols are and their effects on local areas and the planet's climate as a whole.]]></description>

<title><![CDATA[Readiness Polls Coming Up]]></title>
<description><![CDATA[One hour before launch, the Glory countdown remains in its standard hold. During this pause, the launch team will conduct readiness polls to move the countdown into the phase known as the &quot;hot count&quot; leading to launch. It gives the operators a chance to review all the systems on the spacecraft and the rocket and determine whether everything remains &quot;go&quot; for launch. There is a 5-minute hold coming up at the T-12 minute point.]]></description>

<title><![CDATA[Taurus XL in Spotlight This Morning]]></title>
<description><![CDATA[A Taurus XL rocket stands on a short base this morning at Vandenberg Air Force Base, Calif., ready to launch the Glory spacecraft on a mission designed to last at least three years. The four-stage rocket tops out at 97 feet with the 63-inch payload fairing used for today's mission. A larger fairing is available that pushes the Taurus' length to 104 feet. It weighs 170,000 pounds and all four of its stages burn a solid propellant, which is a mixture of chemicals that are about the consistency of a pencil eraser. The fuel is molded inside each stage of the rocket and once it is ignited, it cannot be turned off. One of the advantages to solid fuel is that it doesn't require turbopumps and the other complex hardware that constitutes an engine for a liquid-fueled rocket.]]></description>

<title><![CDATA[Launch Services Program Managing Liftoff]]></title>
<description><![CDATA[NASA's Launch Services Program is handling the launch this morning of the Glory mission. The program is based at Kennedy Space Center and conducts launches all over the world, including today's in California. The launch team also manages missions that are launched from the Kwajalein Atoll in the Pacific.<br/><br/>The launch team's work begins years before a launch when managers choose which rocket to use to lift a given spacecraft. Sometimes, like today, the spacecraft is destined for a short ride to Earth orbit, so a small launcher is in order. Other missions are meant for deep space, such as the New Horizons mission now heading toward Pluto. Those missions require much more power for launch, so bigger rockets are employed. An Atlas V was used to launch the New Horizons mission, for example.<br/><br/>NASA's Goddard Space Flight Center in Greenbelt, Md., is managing the Glory mission itself.]]></description>

<title><![CDATA[West Coast Launch for Glory]]></title>
<description><![CDATA[Today's Glory mission begins on the West Coast, specifically at Space Launch Complex 576-E at Vandenberg Air Force Base, Calif. The mission requires the spacecraft to have a look at all parts of the earth, which means it must go into a polar, or sun-synchronous, orbit. Such an orbit is roughly perpendicular to the equator, taking the spacecraft over the Earth's north and south poles on each revolution. From there, the spacecraft can see all parts of the Earth as the planet spins beneath it.]]></description>

<title><![CDATA[Launch Day for Glory!]]></title>
<description><![CDATA[Welcome to this morning's continuous coverage of the countdown for the Glory mission. Launch time is 5:09 a.m. EST and the weather forecast is positive. The launch window is 48 seconds this morning. It will take Glory 13 minutes to reach orbit and separate from its Taurus XL booster. After finalizing its orbit and checking out its equipment, the Glory spacecraft will begin its mission of surveying aerosols in the Earth's atmosphere to help researchers determine their role in the planet's climate. The spacecraft also carries an instrument that measures the sun's irradiance.<br/><br/>This is the second launch attempt for the Earth-observation mission, following a scrub last week because of a technical issue with the ground support equipment for the rocket. On Feb. 23, a false indication was received about the rocket's status after commands were sent about 15 minutes before launch to activate the Taurus. <br/><br/>The launch team has remedied the issue though, and they are ready to go ahead with this morning's liftoff. As for us, we will bring details of the countdown as it progresses and provide some background about this fascinating mission and what scientists hope to learn from it.]]></description>

<description><![CDATA[The Glory spacecraft and its Taurus XL rocket are poised for launch Friday morning at 5:09 a.m. EST from Vandenberg Air Force Base in California. Our continuous coverage of the countdown and liftoff will begin at 3:30 a.m. EST. The mission for Glory is to survey aerosols in Earth's atmosphere to help determine their effect on the planet's climate. It also carries an instrument to measure the sun's irradiance and add that piece to the climate puzzle for researchers.]]></description>
