Alast-of-its-kind weather observatory with roots reaching back to the earliestdays of U.S. space exploration rocketed into orbit this morning to keep loggingenvironmental records until a long-delayed new generation of satellites isready.
Shrouded inside the whitenose cone the Delta 2 rocket, the NOAA-N Prime spacecraft left its coastallaunch pad in California at 2:22 a.m. local time (5:22 a.m. EST; 1022 GMT).
The satellite's family treecan be traced to 1960 and the launch of TIROS, the first Television InfraredObservation Satellite. Upgrades and technology advancements have evolved thecivilian weather observatories through the decades. NOAA-NPrime is 43rd satellite launched in the long line and the 16th from itsparticular series that dates to 1978.
"Since the 1960s,we've gone from collecting and generating somewhat fuzzy cloud images ofweather systems to producing crisp images of clouds, land and ocean features,collecting information about the vertical distribution of temperature andmoisture in the atmosphere and developing products to support our broad rangeof environmental applications. So we've gone from launching weather satellitesto environmental satellites," said Mike Mignogno, NOAA's program managerof Polar Operational Environmental Satellites.
"NOAA-N Prime is goingto give us data the same as we've been getting in the past, but its main roleis continuity of service and to restore some of the degraded instruments thatwe've had," said Tom Wrublewski, the satellite's acquisition manager."So we're looking forward to a fresh satellite that has 100 percent ofeverything working and also help us continue our services until the nextgeneration NPOESS satellites are ready."
But the new NPOESS satelliteshave been beset by technical and money problems, delaying the first craft'slaunch to January 2013.
"The NPP satellite,which carries the instruments that the NPOESS satellite is carrying, will giveus the insurance of having a backup in orbit if for some reason N Prime failsbefore the launch and checkout of (the first NPOESS)," said Gary Davis,director of the Office of Systems Development at NOAA's Satellite andInformation Service.
Circling 530 statute milesabove Earth and completing a revolution every 100 minutes, the NOAA-N Primewill operate in the so-called "afternoon" polar orbit to replaceNOAA-18 and its degraded instruments. The orbit crosses the equator from southto north at 2 p.m. local time on each trip around the planet.
A joint endeavor betweenNOAA and Europe's weather satellite agency has the "morning" orbitcovered. The first MetOp satellite in that collaborativeproject launched in 2006.
"It's a goodcooperation," Mignogno said. "We share the data and we both benefitfrom the fact that we're each providing only one satellite but getting thebenefit of two."
"The data frompolar-orbiting satellites such as NOAA-N Prime will be vital to our mission aswe move forward to monitor and to predict not only current conditions in theatmosphere and oceans but also to keep tabs on the longer term climatetrends," said Wayne Higgins, director, NOAA's Climate Prediction Center.
The Lockheed Martin-builtsatellite also carries an instrument to study the quantity and extent of ozonein the atmosphere and a space environment monitor that measures changes in theEarth's magnetic field and radiation belts caused by solar storms that canthreaten astronauts and impact terrestrial communications, according to WayneMcIntyre, NASA's program manager for the Polar Operational EnvironmentalSatellites.
NOAA-N Prime had toovercome the perils of its past to even reach space. In September 2003, the spacecraftwas severely damaged in a factory accident, falling on its side while being moved becauseworkers failed to realize the satellite wasn't bolted to the handling cart.Extensive work went into rebuilding the craft.
Twoback-to-back scrubs for pad-related glitches kept NOAA-N Prime on theground a couple extra days this week, but the wait resulted in today's flawlessascent to orbit.
"The flight was justawesome. We hit the orbit right on the money. The apogee, perigee andinclination of the spacecraft looks right where we wanted it," NASA launchmanager Omar Baez said.
"We are proud tocelebrate the 20th anniversary of Delta 2 by successfully launching thiscritically important spacecraft for both NASA and NOAA and we congratulate ourmission partners on their success," said Jim Sponnick, United LaunchAlliance's vice president of the Delta Product Line.
"A bunch of peoplethat worked on this program for the full 30 years are all going to get togethera couple weeks after the successful launch of N Prime and just reminisce aboutan era that's come to an end," Davis said.
"I think this is avery storied program," Mignogno said. "I think it's going to be atough act to follow."
