Let Private Corporations manage Safety issues-----keep Gov./NASA out of loop!!

The Sierra Nevada Corporation announced its selection of Lockheed Martin Space Systems as its "Dream Chaser" partner.

SNC has had an ongoing relationship with NASA in its Commercial Crew Program. The Dream Chaser is being designed to carry up to seven people to, and from, low earth orbit. The current focus is sending crew and cargo to the ISS, with a built-in launch escape system. This craft will be able to fly autonomously if needed, and will be able to land on any normal, commercial runway.

This is but one example of how NASA is helping commercial firms develop new technologies. Let congress know that you approve of NASA's economic contributions, and that you wish to see more of these types of investments.
Like ·  ·  · 
  • Bobby Martin Gehman & dyer will not let it fly----too dangerous
  • Bobby Martin What will happen, an accident will occur, board establish , months to years delay, after many iterations, a board chairman will pronounce too dangerous ----repeat of Columbia, challenger---just observe & document.
  • David R. Maier So... It's a bet, then, eh?  lol
  • Bobby Martin If you read Krantz 's articles he is quite perplexed re: unwillingness to take risks---read ASAP minutes from 2000 to 2007. Read CAIB report & challenger accident report. Ultimate safety --don't fly.
  • David R. Maier Hopefully we'll find out... But, I can't imagine these huge space corporations taking that kind of gamble without confidence it'll fly...
  • Bobby Martin Good point , be interesting how they avoid gov, beauracy---NASA ASAP , FAA ---they the companies can get it done---must be done like DOD , not NASA who overly glorified astronauts. That can not be repeated, if so we will be bogged down overly dwelling on death of few astronauts whereas go read DOD reports on test aircraft.

What will happen to underfunded efforts like cots, dream chaser, Orion ?? Disaster--shuttle cycle repeats

Look at Apollo, shuttle, as time went by & more got killed, safety became a bigger concern. Apollo, shuttle had considerable funding as compared to some of the underfunded new starts.

After a fatality accident, accident board will convene, big delay, rework, and then a few flights, and another accident, hence the cycle repeats,

Unless we get competent leadership, doubtful we can regain Preeminence in space!!!

Sierra Nevada welcomes Lockheed Martin to Dream Chaser project

01/30/2013 02:49 PM 

By WILLIAM HARWOOD
CBS News

Lockheed Martin Space Systems Co. is joining Sierra Nevada Corp.'s Dream Chaser commercial manned spacecraft program, bringing the aerospace giant's expertise in flight certification and composites manufacturing to the private-sector initiative, company officials announced Wednesday.

Sierra Nevada is competing with Space Technologies Corp. and Boeing to develop a new generation of commercial space taxis that NASA envisions hiring to ferry astronauts to and from the International Space Station.

Unlike its rivals, which are designing wingless capsules that initially, at least, would make parachute descents to ocean splashdowns, Sierra Nevada's Dream Chaser is a winged lifting body that would launch atop an Atlas 5 rocket and re-enter the atmosphere much like a space shuttle, gliding to a runway landing.

The spacecraft can be launched manned, carrying up to seven astronauts, or unmanned, loaded with cargo, scientific experiments or both.

The contract announced today will bring Lockheed Martin's long experience in flight certification requirements to the Dream Chaser program and add manufacturing capability at Lockheed Martin's Michoud, La., plant where the company once built space shuttle external tanks.

"There's so much depth within the Lockheed Martin organization that we haven't been able to access," said Sierra Nevada Vice President Mark Sirangelo, leader of the Dream Chaser project. "We asked ourselves the question, how can we do that?

"And that has led to the beginning of a very exciting and very expansive relationship where Lockheed has joined our Dream Chaser team as an exclusive partner to help us with the certification, which is how do we get this vehicle really fit to fly safely?"

The certification work will cover "the things that are going to be necessary to fly human beings to orbit on a system that's supposed to be something that flies frequently," Sirangelo told reporters. "We're going to combine our knowledge ... We think this is a terrific thing, not only for us and our program, but for NASA."

The value of the contract was not revealed.

Lockheed Martin is the prime contractor for NASA's Orion spacecraft, a manned capsule originally intended for the Bush administration's Constellation moon program. NASA now plans to use Orion and a new heavy-lift booster for government-directed deep space voyages to a variety of targets.

The commercial manned spacecraft initiative is a bid by the Obama administration to kick-start development of private-sector vehicles that can take over more routine flights to and from low-Earth orbit.

Last August, NASA announced that Boeing, SpaceX and Sierra Nevada had been selected to continue spacecraft development work under the agency's Commercial Crew Integrated Capability Initiative, or CCiCap. Boeing's contract was valued at up to $460 million, SpaceX won a contract worth up to $440 million while Sierra Nevada was awarded $212.5 million.

Sirangelo said the Dream Chaser spacecraft will be fully reusable and relatively inexpensive to operate. Just as important, he said, it can be flown manned or unmanned to meet a wide variety of mission objectives.

"We view this as a transportation system to low earth orbit," he said. "For example, the vehicle in a long duration capacity unmanned could act as a science platform. There is the potential for the vehicle to do servicing in space, satellite servicing or other types of servicing."

"If there are other destinations, other than the space station, that are built, we could provide transportation. We also have the capability to bring people up to expand the envelope for what would currently be a very burgeoning, young, suborbital tourist market for those people who want to go to the next level."

Jim Voss, a former shuttle and space station astronaut who now serves as vice president of Sierra Nevada's Space Exploration Systems, said an engineering test version of the Dream Chaser will be flown to Edwards Air Force Base, Calif., in two weeks for the start of initial helicopter drop tests in about six weeks.

The unmanned test vehicle "will be released from a helicopter and it will fly down and land autonomously on a runway and we'll gather the aerodynamic data we need to complete our aerodynamic database for the Dream Chaser," Voss said.

Private Space Plane Poised for Big Test Flight

by Mike Wall, SPACE.com Senior Writer

30 January 2013 Time: 02:00 PM ET

 

 

A private space plane is slated to fly on its own for the first time in the next six to eight weeks, a key drop-test milestone in the vehicle's quest to fly astronauts on roundtrip space missions.

The Dream Chaser spacecraft, built by aerospace firm Sierra Nevada Corp., will be released by a carrier helicopter at an altitude of 12,000 feet (3,657 meters) or so, then fly back and land autonomously on a runway at NASA's Dryden Flight Research Center in California.

The unmanned 30-second drop test will kick off a series of trials that culminate in trips to low-Earth orbit and back, potentially paving the way for contracted, crew-carrying flights to the International Space Station for NASA, company officials said during a press conference today (Jan. 30).

The seven-passenger Dream Chaser looks a bit like a miniature space shuttle. It's about 29.5 feet (9 m) long and has a wingspan of 22.9 feet (7 m). For comparison, NASA's space shuttle was 122 feet (37 m) long, with a wingspan of 78 feet (24 m). [Gallery: Meet the Dream Chaser Space Plane]

Filling the space shuttle's shoes

Colorado-based Sierra Nevada is one of several spaceship-building companies to receive funding from NASA's commercial crew program, which is encouraging private American vehicles to fill the void left by the space shuttle fleet's retirement in 2011.

In its latest round of awards, NASA granted funding to Sierra Nevada for the Dream Chaser and to SpaceX and Boeing, which are working on capsules called Dragon and the CST-100, respectively. The Dream Chaser space plane is the only non-capsule design being developed by a major contender.

The space agency hopes at least one of these vehicles is ready to fly astronauts to and from the space station by 2017. Until such homegrown private spaceships come online, NASA and the nation are dependent on Russian Soyuz spacecraft to provide this orbital taxi service.

The newly announced drop test is a step along the path to orbit. It will mark the first time the Dream Chaser has ever flown solo, though the space plane did take to the skies last year in a captive-carry test, during which it was held aloft the entire time by a heavy-duty helicopter.

The Dream Chaser drop-test vehicle is currently at a facility in Colorado, but it will be moved to Dryden in about two weeks, officials said. The first flight test should come four to six weeks after that, with two to five more flights following to gather additional data about the vehicle's in-air performance.

"The first flight test is just to make sure it will fly, everything works properly, we land on the runway safely," said Sierra Nevada's Jim Voss, head of the Dream Chaser program and a former space shuttle astronaut. "We'll put in maneuvers on the following tests that will gather the coefficients that we need to properly define the aerodynamic characteristics of the vehicle."

A testing campaign

If everything goes well with the upcoming series of tests, Sierra Nevada will conduct more extensive flight trials with another Dream Chaser vehicle, officials said.

"It will be similar to this vehicle, but we'll be able to pilot it with a test pilot on board, and then that same vehicle will be ultimately used for an orbital flight to demonstrate the capability of the Dream Chaser in orbit," Voss said.

Aerospace giant Lockheed Martin will help build that more advanced flight-test vehicle, as part of an extensive partnership with Sierra Nevada that the companies just announced today.

"They're building the structure for that vehicle, as we finish the design of some of the other systems we'll use for that additional flight test that we'll do in about a year to 18 months," Voss said.

In Two Weeks This 50-Meter Asteroid Will Buzz Our Planet

by Jason Major on January 30, 2013
 
2012DA14
 Asteroid 2012-DA14 will pass Earth closely on Feb. 15, 2013 (NASA)
On February 15 a chunk of rock about 50 meters wide will whiz by Earth at nearly 8 km/s, coming within 27,680 km of our planet's surface — closer than many weather and communications satellites.
For those of you more comfortable with imperial units, that's 165 feet wide traveling 17,800 mph coming within 17,200 miles. But regardless whether you prefer meters or miles, in astronomy that's what's called a close call.
Scientists stress that there's no danger of an impact by this incoming asteroid, designated 2012-DA14, but it's yet another reminder that in our neck of the Solar System we are definitely not alone.
 
http://www.youtube.com/watch?feature=player_embedded&v=GwidzVHvbGI
 
"2012-DA14 will definitely not hit Earth," says JPL's near-Earth object specialist Don Yeomans. "The orbit of the asteroid is known well enough to rule out an impact."
But with 2012-DA14′s upcoming February flyby Yeomans notes, "this is a record-setting close approach."
The rocky asteroid will come within about 4 Earth radii, which is well within the orbits of geosynchronous satellites. During its closest approach at 19:26 UTC it should be visible in the sky to amateur telescopes (but not the naked eye), becoming as bright as an 7th- or 8th-magnitude star.
2012da14_s
Radar observatories will be watching 2012-DA14 during the days leading up to and following its approach in an attempt to better determine its size, shape and trajectory. NASA's Goldstone facility will have an eye — er, dish — on DA14, but it won't be visible to Arecibo. Stay tuned for more info!

NASA Launches Next-Generation Communications Satellite

 

 

CAPE CANAVERAL, Fla. -- The first of NASA's three next-generation Tracking and Data Relay Satellites (TDRS), known as TDRS-K, launched at 8:48 p.m. EST Wednesday from Cape Canaveral Air Force Station in Florida.

"TDRS-K bolsters our network of satellites that provides essential communications to support space exploration," said Badri Younes, deputy associate administrator for Space Communications and Navigation at NASA Headquarters in Washington. "It will improve the overall health and longevity of our system."

The TDRS system provides tracking, telemetry, command and high-bandwidth data return services for numerous science and human exploration missions orbiting Earth. These include the International Space Station and NASA's Hubble Space Telescope.

"With this launch, NASA has begun the replenishment of our aging space network," said Jeffrey Gramling, TDRS project manager. "This addition to our current fleet of seven will provide even greater capabilities to a network that has become key to enabling many of NASA's scientific discoveries."

TDRS-K was lifted into orbit aboard a United Launch Alliance Atlas V rocket from Space Launch Complex-41. After a three-month test phase, NASA will accept the spacecraft for additional evaluation before putting the satellite into service.

The TDRS-K spacecraft includes several modifications from older satellites in the TDRS system, including redesigned telecommunications payload electronics and a high-performance solar panel designed for more spacecraft power to meet growing S-band requirements. Another significant design change, the return to ground-based processing of data, will allow the system to service more customers with evolving communication requirements.

The next TDRS spacecraft, TDRS-L, is scheduled for launch in 2014. TDRS-M's manufacturing process will be completed in 2015.

NASA's Space Communications and Navigation Program, part of the Human Exploration and Operations Mission Directorate at the agency's Headquarters in Washington, is responsible for the space network. The TDRS Project Office at NASA's Goddard Space Flight Center in Greenbelt, Md., manages the TDRS development program. Launch services were provided by United Launch Alliance. NASA's Launch Services Program at the Kennedy Space Center was responsible for acquisition of launch services.

CAPE CANAVERAL — A powerful Atlas V rocket roared off its Cape Canaveral launch pad Wednesday, propelling a critical NASA communications satellite toward orbit.
The 192-foot-tall Atlas V blasted off from Launch Complex 41 at Cape Canaveral Air Force Station at 8:48 p.m., the first rocket launch from Florida's Space Coast this year.
The United Launch Alliance booster rose into the night sky, appearing as a bright, white fireball as it rumbled toward an orbital perch 22,300 miles above the planet.
Riding aboard the Atlas V: a NASA Tracking and Data Relay Satellite. The 7,600-pound TDRS spacecraft will act as an orbital switchboard, relaying voice communications and data between the International Space Station and ground stations.
Mission Control can maintain almost constant contact with the outpost and its crews as a result of the TDRS spacecraft.
Other NASA spacecraft – including the Hubble Space Telescope – also will use the satellite. So will spacecraft operated by the U.S. Department of Defense.
NASA developed TDRS spacecraft to improve communications with orbiting spacecraft. They also enabled the agency to close down worldwide ground stations that supported the Mercury, Gemini, Apollo and Skylab programs. The ground stations were expensive to operate and hard to maintain.
Ten NASA Tracking and Data Relay Satellites already had been launched before Wednesday, the first in 1983. Seven of those still are operating. One was lost in the 1986 Challenger accident, which occurred 27 years ago this week.
The 11th was the first of a new-generation being built by The Boeing Co. NASA officials say that spacecraft, another to be launched next year, and modifications to a ground station in New Mexico cost $715 million.
Next up at Cape Canaveral: the March 1 launch of a SpaceX Falcon 9 rocket and a Dragon spacecraft. The flight will be the second of 12 cargo resupply missions SpaceX is launching to the International Space Station under a $1.6 billion NASA contract.

Atlas 5 puts science-relay satellite into orbit for NASA
BY JUSTIN RAY
SPACEFLIGHT NOW

January 30, 2013

Advancing from the days of ground stations providing sporadic coverage of man's early exploits in space to the creation of an orbiting satellite network for constant communications, the third generation of NASA's tracking stations in the sky roared off the launch pad Wednesday night.

A United Launch Alliance Atlas 5 rocket, capping its quickest pre-flight processing flow to date, fired into the nighttime sky from Cape Canaveral's Complex 41 at 8:48 p.m. EST (0148 GMT).
At just 27 days from the start of stacking to main engine ignition, ULA's efforts at "span reductions" bore fruit by besting the previous quick mark by two weeks. The launch provider says the improved tempo will heighten efficiencies, increase available slots in the manifest and cut costs.
"It offers our customers added manifest flexibility to meet their schedules and it also offers additional launch opportunities to ensure payloads can be launched on time and reliably," said Vern Thorp, ULA's program manager for NASA missions.
Displaying that reliably Wednesday night on its 35th mission in a decade and the 8th for NASA, the Atlas-Centaur artfully propelled the Tracking and Data Relay Satellite K into its prescribed orbit, reaching an elliptical orbit with a high point of 22,245 statute miles, low point of 2,680 statute miles and inclination of 25.6 degrees.
Lasting an hour and 46 minutes from departing the launch pad through deployment of the payload in the geosynchronous transfer orbit, the ascent went exactly as planned to bolster NASA's in-space communications infrastructure.
"Launch is just the beginning of this satellite's journey, and the addition of TDRS K to the overall constellation will continue the successful legacy of the project and strengthen NASA's communications system that is so vital to the International Space Station and many other satellites in orbit today and will be in the future," Thorp said.

The TDRS system was born in 1973 to keep astronauts and satellites in constant contact with mission controllers, closing the substantial gaps every orbit as spacecraft passed into and out of range of ground stations scattered around the globe.
When TDRS first became operational in late 1983, the initial space shuttle mission to use the system relayed more information to the ground during its 10 days in orbit than in all 39 previous American manned spaceflights.
Relying on dispersed ground stations was a costly requirement and subjected the sites' operators to dangerous conditions in far-off countries, yet the system provided only 15 percent communications capability per orbit.
"What would it take to have continuous 24/7 communications services for NASA missions? That is what prompted the TDRS constellation," said Paul Buchanan, TDRS deputy project manager and contracting officer.
"We didn't want to the outages of voice or data, that prompted to the TDRS system to be designed and built."
Prolonged disconnections were eliminated with the debut of TDRS, effectively moving those tracking stations 22,300 miles into the sky to gaze down at the user spacecraft, upping the blanket coverage to 85 percent per orbit with two operational TDRS satellites.
But looking to close that remaining gap, or zone of exclusion, more spacecraft were put into operation to create full 100 percent orbital coverage.
Six of the seven first-generation satellites went into orbit, with one lost in the Challenger accident. The space shuttles deployed those TRW-built craft between 1983 and 1995, with four of the long-lived birds still doing the job today 22,300 miles above Earth.
"As spacecraft age, they all kind of develop their own unique set of problems, especially for spacecraft beyond their design life. So each one has to be cared for in different ways," said Jeff Gramling, NASA's TDRS project manager from the Goddard Space Flight Center.
But despite their advanced ages, they remain useful, and the demands of communications services continue to grow.
"We've been fortunate in that our first-generation spacecraft, the one of those we launched through 1995 with a 10-year design life, have lived well beyond the design life. That has given us the time to make sure are able to repopulate or recapitalize the network," said Gramling.

A second-generation came along between 2000 and 2002, as the TDRS H, I and J satellites were deployed by unmanned Atlas 2A rockets from Cape Canaveral to improve the capabilities of the network.
Now, Boeing is building the K, L and M spacecraft for launches over the next three years to keep the system replenished and operating well into the 2020s.
"What we are doing is ensuring that we can continue provide services that they've come to rely on -- persistant, continuous coverage with no latiency to facilitate their missions," Gramling said.
"Lots of people out there are relying on the system and we need to make sure we keep it healthy to satisfy their needs."
TDRS L should be ready to fly next January and M will follow in December 2015.
"Architecturally they are the same as HIJ with a little better performance," Gramling said. "From a users' perspective, its generally continuing to provide the same services we provided in the past."
This first of the third-generation, known as the Tracking and Data Relay Satellite K, or TDRS K, is headed for service 22,300 miles over the Pacific Ocean.
"TDRS K bolsters our network of satellites that provides essential communications to support space exploration," said Badri Younes, deputy associate administrator for Space Communications and Navigation at NASA Headquarters. "It will improve the overall health and longevity of our system."
The satellite stood 26 feet tall and weighed over 7,600 pounds at launch, including 3,700 pounds of maneuvering fuel loaded inside the craft. Once fully deployed in space, TDRS K's solar wings will stretch 69 feet tip-to-tip to generate 3,220 watts of power and charge internal nickel-hydrogen batteries.
The primary physical feature of the satellite is two 15-foot-diameter flexible graphite mesh antenna dishes that are folded like taco shells for launch, then spring into shape once released in orbit. They offer gimbal tracking of targeted spacecraft flying beneath the satellite, providing high-gain communications to the station, Hubble and other craft for vital contacts and data dumps.
S-band, Ka-band and Ku-band are the frequencies supported through the TDRS network.

"The voice and data communications the TDRS constellation brings back to Earth every day from the International Space Station, the Hubble Space Telescope and many of our NASA science spacecraft -- it touches each of our lives," said Tim Dunn, the NASA launch director for TDRS K.
Boeing designed, developed and tested the spacecraft in El Segundo, Calif., and NASA provided the launch. Once the aerospace company gets the satellite into the proper orbit, deploys the appendages and demonstrates that the craft works, the space agency then takes ownership for a lifespan of 15 years or more.
"We are launching now for an immediate need and replenishment schedule, we're also expecting some of the other legacy spacecraft from the TRW days to decommissioned in the next years. That's reason for not just K but L and M. It's a fine balance between the existing system, and when they fail, versus the replenishment," Buchanan said.
The three satellites of the third-generation, the Atlas 5 rockets to launch them and some work performed on the ground systems amount to a $1.1 billion program.
"All the Hubble pictures come through TDRS, all the video that we see from the space station and the astronauts and the video we saw from the shuttle, it all comes through TDRS, and then we have all the Earth-orbiting satellites, all that data comes through TDRS," Buchanan said.
"The government has designated TDRS as a critical national asset due to the fact that continuous communications around the world is critical to people's security, weather-related events, that's the important value NASA provides."
Wednesday's launch was the 35th flight for the Atlas 5 since debuting in 2002 and the 30th to occur from the Florida spaceport. Next up is deployment of an advanced Landsat spacecraft for NASA and the U.S. Geological Survey on Feb. 11 from Vandenberg Air Force Base in California.
The next Atlas launch from Cape Canaveral is planned for mid-March carrying the Air Force's second Space Based Infrared System Geosynchronous satellite, or SBIRS GEO 2, for missile early-warning detection.

Liftoff! NASA Launches Next-Generation Relay Satellite into Space

by Miriam Kramer, SPACE.com Staff Writer

Date: 30 January 2013 Time: 08:48 PM ET

 

 

This story was updated at 10:46 p.m. ET.
A next-generation NASA relay satellite was launched into orbit Wednesday (Jan. 30) on a mission to upgrade a vital communications network linking the space agency to its spacecraft orbiting the Earth.
The U.S. space agency's first launch of 2013, the new Tracking and Data Relay Satellite K (TDRS-K for short) soared spaceward atop a United Launch Alliance Atlas 5 rocket from Cape Canaveral Air Force Station in Florida at 8:48 p.m. EST (0148 Jan. 31 GMT).
"We have a customer that's quite thrilled right now to have a healthy satellite on orbit," Tim Dunn the TDRS-K flight director said in a NASA TV interview after the launch.
The TDRS-K satellite is bound for an orbit 22,300 miles (35,888 kilometers) above Earth, where it will join a constellation of five other satellites currently in orbit to help NASA and other space agencies stay in touch with orbiting spacecraft.
NASA's TDRS communications network began in 1983 and has not received an upgrade since 2002, when the space agency launched its 10th TDRS satellite. Five satellites are currently in use today, with the TDRS-K launch adding one more that number, mission managers said. [Launch Photos: NASA's TDRS-K Satellite Blasts Off ]

The TDRS-K satellite is expected to spend at least 15 years, but agency officials expect that the satellite will exceed its projected life-expectancy. Many of the network's satellites have outlived their expected mission lifetimes,  said Jeffrey Gramling, NASA's TDRS project manager.
But that does not mean that TDRS-K is unnecessary. One of the satellites currently in active service is slated be retired in the next few months, and other satellites in the aging network are getting older, said Badri Younes, a scientist in NASA's Space Communications and Navigation office.
The satellite launched today was the first of three new satellites expected to enter service between now and 2015 that should further bolster the network. The TDRS-K mission costs between $350 million and $400 million, not including the price of its rocket.
The TDRS-K satellite is 26 feet long (8 meters) and weighs about 7,615 pounds (3,454 kilograms). It was expected to separate from its Atlas 5 rocket one hour and 46 minutes after liftoff, with a Centaur upper stage rocket engine slated to carry it the rest of the way to its geosynchronous orbit.

The satellite is expected to deploy its solar arrays and giant antennas about 11 days after launch, according to a mission description.  
NASA's TDRS satellite network is part of the larger "Space Network" used keep space agencies on the ground in constant communication with orbiting spacecraft. The International Space Station sends all of its data and messages through the network using the TDRS satellites. The rocket that sent TDRS-K into orbit even uses the space network to beam down data, Vernon Thorp, a program manager with NASA said.
TDRS-K is now entering into a three month period of testing and calibrations, but once those tests are complete the NASA research team will decide if the satellite is ready for service.

NASA launches communication satellite

By MARCIA DUNN | Associated Press

CAPE CANAVERAL, Fla. (AP) — NASA launched a new communication satellite Wednesday to stay in touch with its space station astronauts and relay more Hubble telescope images.
An unmanned Atlas V rocket blasted into the starry night sky carrying the Tracking and Data Relay Satellite.
This is the 11th TDRS satellite to be launched by NASA. The space agency uses the orbiting network to communicate with astronauts living on the International Space Station.
The first TDRS spacecraft flew in 1983; it recently was retired along with No. 4. The second was lost aboard space shuttle Challenger in 1986; Monday marked the 27th anniversary of the launch disaster.
This newest third-generation TDRS carries the letter K designation. Once it begins working, it will become TDRS-11. It will take two weeks for the satellite to reach its intended 22,300-mile-high orbit. Testing will last a few months.
NASA estimates the satellite costs between $350 million and $400 million.
Another TDRS spacecraft, L in the series, will be launched next year.
NASA wants at least seven TDRS satellites working in orbit at any one time. The one launched Wednesday will make eight.

Atlas 5 boosts NASA comsat into space

01/30/2013 10:42 PM 

By WILLIAM HARWOOD
CBS News

A United Launch Alliance Atlas 5 rocket rumbled to life and blasted off from the Cape Canaveral Air Force Station Wednesday evening, lighting up the night sky as it boosted a powerful new NASA Tracking and Data Relay Satellite into orbit.

Valued between $350 mission and $400 million -- not counting the rocket -- the Boeing-built TDRS-K satellite is the first of three new models joining NASA's globe-spanning fleet of high-speed relay stations used by the International Space Station, science satellites and deep space probes.

The 192-foot-tall Atlas 5 rocket's RD-180 first stage engine ignited with a rush of fiery exhaust at 8:48 p.m. EST (GMT-5), quickly throttling up to full power of more than 860,000 pounds of thrust.

Putting on a dramatic evening show for area residents and tourists, the workhorse rocket majestically climbed away from launch complex 41 atop a torrent of brilliant flame and smoothly accelerated as it consumed its first stage liquid oxygen and kerosene propellants.

After arcing away to the east over the Atlantic Ocean, the Russian-designed RD-180 shut down about four minutes after liftoff. Seconds later, the spent first stage fell away and the Centaur second stage's hydrogen-fueled Pratt & Whitney RL-10A engine ignited to continue the push to orbit.

The second stage engine burned for nearly 14 minutes, putting the spacecraft in an initial parking orbit. A second 58-second burn was carried out an hour and 40 minutes after liftoff to complete the launch phase of the mission.

The TDRS satellite then was released into a highly elliptical orbit, with a high point of more than 22,200 miles and a low point of around 2,680 miles.

"We have a successful satellite separation, we just confirmed that by telemetry," said NASA launch director Tim Dunn. "There are a lot of happy folks out there, and we've got a customer who's quite thrilled right now to have a healthy satellite on orbit."

It will take about 10 days to maneuver the TDRS-K satellite into a circular orbit 22,300 miles above the equator at 150 degrees west longitude. Once on station, engineers plan to spend about three months activating, checking out and calibrating the satellite's systems.

If all goes well, the satellite will be moved to 171 degrees west longitude where it will go into service. But depending on demand, mission managers say, the new satellite may be placed in orbital storage until the additional capability is needed.

Tracking and Data Relay Satellites provide tracking and telemetry for a variety of government satellites, planetary probes, launch vehicles and manned spacecraft like the International Space Station.

The latest generation features S-band antennas that can communicate with five other spacecraft simultaneously. Two 15-foot-wide steerable S-band antennas support both manned missions and science probes like the Hubble Space Telescope. High-speed Ka- and Ku-band antennas handle high-resolution video and high-volume science data.

The first TDRS satellite was launched aboard the shuttle Challenger during the sixth space shuttle mission in April 1983. A second TDRS was lost in the 1986 Challenger disaster.

Since then, NASA launched five more TDRS satellites aboard space shuttles and three more aboard Atlas rockets. TDRS-K is the 11th in the series.

This was the 35th launch of an Atlas 5 rocket, the 30th from Cape Canaveral and the eighth use of the rocket by NASA.
