<title><![CDATA[TDRS-K Flies On Its Own]]></title>
<description><![CDATA[The Centaur upper stage separated from the TDRS-K spacecraft on time, releasing it in a geosynchronous transfer orbit. The TDR-K carries small thrusters that will spend the next 10 days circularizing the spacecraft's orbit at an altitude of 22,300 miles. From that position, the TDRS-K, like the others before it, will be able to relay signals from NASA spacecraft orbiting the Earth to ground stations. TDRS users include the International Space Station, NASA's Hubble Space Telescope and the agency's fleet of Earth observation satellites.]]></description>

<description><![CDATA[The Centaur's RL-10 engine has shut down as planned to set the TDRS-K spacecraft on a coasting track. The Centaur will re-ignite in an hour and 22 minutes to send the TDRS-K into a geosynchronous transfer orbit. After the second burn, the Centaur will separate from the TDRS-K and the spacecraft's own thrusters will spend the next 10 days circularizing the orbit at 22,300 miles above Earth.]]></description>

<title><![CDATA[All Systems 'Go' as Centaur Takes Over]]></title>
<description><![CDATA[The TDRS-K spacecraft continues its smooth climb into space after the first stage of the Atlas V rocket falls away and the Centaur upper stage engine ignites. The payload fairing that protected the communications satellite during the first part of ascent separated on time and has fallen away to reveal the TDRS to space. The Centaur's engine will pause in a few minutes to begin a coast phase before it reignites to put the TDRS-K on a path to its final destination 22,300 miles above the planet.]]></description>

<title><![CDATA[Liftoff! TDRS-K Headed To Orbit!]]></title>
<description><![CDATA[Smoke and fire billows from the first stage of a United Launch Alliance Atlas V this evening as it soars off its launch pad in Florida to lift NASA's TDRS-K spacecraft into orbit. The first stage is powered by an RD-180 engine system that is propelling the rocket and its payload to an orbit 22,300 miles above the Earth. The Centaur upper stage will take over four minutes, two seconds after liftoff when the first stage consumes its propellants.]]></description>

<title><![CDATA[Atlas V/Centaur Fueling Complete]]></title>
<description><![CDATA[The Atlas V first stage and Centaur upper stage have been loaded with propellants for tonight's launch. Pumps at the pad will continue to trickle in super-cold liquid oxygen and liquid hydrogen as needed to replace the chemicals as they boil off during the last part of tonight's countdown. The launch team at Cape Canaveral Air Force Station in Florida reports no technical issues and the weather remains within limits for liftoff, scheduled for 8:48 p.m. EST at the start of a 40-minute window.]]></description>

<title><![CDATA[Atlas V Propellant Loading Under Way]]></title>
<description><![CDATA[The launch team is loading cryogenic propellants into the Atlas V first stage and Centaur upper stage this evening as the countdown moves along on schedule toward a liftoff at 8:48 p.m. EST. The Atlas V first stage operates on refined kerosene and liquid oxygen. The kerosene fuel was pumped into the Atlas V Tuesday. The Centaur engine burns liquid oxygen and liquid hydrogen. As for the TDRS-K spacecraft itself, it was fueled during processing. It will use its small thrusters to circularize and refine its orbit during the course of 10 days to reach its orbital checkout position about 22,300 miles above Earth.]]></description>

<title><![CDATA['Go' for Atlas V Tanking]]></title>
<description><![CDATA[NASA's Tracking and Data Relay Satellite-K awaits liftoff atop a United Launch Alliance Atlas V 401 rocket. Countdown clocks resumed counting from T-2 hours at 6:23 p.m. EST. The two-stage Atlas V 401 is ready for fueling at Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. Launch managers and controllers are conducting tonight's countdown from the Atlas Spaceflight Operations Center a few miles south of the launch pad. NASA Launch Manager Tim Dunn and United Launch Alliance Launch Conductor Ed Kitta have polled their respective teams and given the go-ahead to start fueling procedures, or "tanking," which will begin momentarily with chill down of the transfer lines to adjust the hardware to the cold propellant temperatures. The Atlas V booster stage uses 48,860 gallons of liquid oxygen and 25,540 gallons of RP-1, a refined kerosene that was loaded Tuesday. The Centaur's main engine is powered by 4,150 gallons of liquid oxygen and 12,680 gallons of liquid hydrogen.<br/><br/>Weather remains 70 percent favorable for launch during a 40-minute window that opens at 8:48 p.m. EST. A frontal boundary is expected to stay to the north of the pad throughout the countdown and be near Jacksonville at the time of liftoff. There is no significant threat of lightning or rain showers. The main concern is for winds at the launch pad exceeding the limit. Weather currently is go.]]></description>

<title><![CDATA[TDRS-K Launch Rescheduled to Jan. 30]]></title>
<description><![CDATA[The launch of NASA's TDRS-K Tracking and Data Relay Satellite aboard a United Launch Alliance Atlas V rocket is being rescheduled to Jan. 30. The launch window is 8:48 to 9:28 p.m. EST, a duration of 40 minutes. The one-day postponement allows technicians additional time to replace an Ordnance Remote Control Assembly (ORCA) that gave an anomalous signal indication prior to planned ordnance connections.<br/><br/>The standard Launch Readiness Review is scheduled for Monday, Jan. 28. At the conclusion of this review, the go is given for the Atlas V rollout to the launch pad. The prelaunch news conference will then be held at 1 p.m. Rollout is targeted for 10 a.m. on Tuesday, Jan. 29. News media should be at the KSC Press Site at 9 a.m. for transportation to view the rollout.<br/><br/>Launch coverage on NASA Television and the Web will begin at 6:15 p.m. on Jan. 30.]]></description>
