Final countdown for space industry
By Stefan Korshak POST STAFF WRITER
Clouded with yellow smog and dotted with stagnant factories, the gritty industrial city of Dnipropetrovsk was once the heart of the Soviet Union's race with the United States into space. Today the city's massive white brick Yuzhmash complex - Pivdenmash in Ukrainian, which isn't heard much in Dnipropetrovsk - is one of the few Ukrainian companies left still employing thousands in high-tech engineering and manufacture. But if Yuzhmash doesn't quickly turn around its flagship product's reputation for low reliability, space technologies could well be added to the long list of 21st-century industries Ukraine should have had. A Yuzhmash Zenit-2 rocket is scheduled to hurl a Russian Cosmos telecommunications satellite into orbit from Kazakhstan's Baikonur Cosmodrome sometime in December. If that mission flies as scripted, Ukrainian Space Agency officials expect to be tossing satellites into orbit by the covey before the century is out. "As international communications moves toward low-level satellite systems with global coverage, demand is high for launch vehicles like Zenit," said Aleksandr Negoda, the agency's general director. "We see great possibilities for the Ukrainian space industry." But if December's mission ends in a ball of fiery debris as the last Zenit launch did on Sept. 9, Ukrainian rocketry is likely going nowhere but down. Aboard were a dozen Globalstar satellites worth some $190 million, Ukraine's second commercial payload in its history as an independent space power. The timing could hardly have been worse.
Nowhere to go but up The ill-fated mission was a minuscule piece of some of the biggest action on the planet. The likes of Motorola and DirecTV - never mind Bill Gates and Rupert Murdoch - are racing furiously to stuff the Earth's skies with between 1,700 and 2,500 low-orbit satellites by the end of the next decade. Globalstar is a $2.5 billion player aiming for a slice of just one of the markets all those satellites will open up: handheld satellite telephony. Globalstar once hoped to be the first company to offer handheld mobile phones that work equally well in remote parts of Siberia and the Amazon rain forest as on the streets of Manhattan. The crash handed that history-making achievement to Globalstar's competitor, Iridium, a consortium led by Motorola. An international consortium led by the U.S. company Loral Space and Communications, Globalstar plans to fire 48 satellites into orbit by the end of 1999. It originally planned to launch 36 of those satellites on Zenits by the end of this year. The first four Globalstar birds uneventfully achieved orbit aboard a McDonnell Douglas Delta rocket launched from Cape Canaveral, Florida, on April 24. The Delta is a tried-and-true delivery system. Over the years and dozens of launches, the U.S. rocket has gone erratic - blown up in flight, fallen over on the pad, or zoomed off on a tangent - roughly one shot in 20, which is pretty good by most standards. But the roughly $50 million that Loral paid to get those four satellites in space was not the best deal going, some industry analysts argue. "The Delta-2 (6925 and 7925 configurations) has proved reliable, but it is too small," Josh Hopkins, an industry researcher, wrote in article posted on the Internet. "It is not the most efficient way to throw significant weight into space." France's Ariane-4 and U.S. Martin-Marietta's Atlas-2a are fairly comparable to the Delta in cost and capacity. Ukraine's hulking, two-stage Zenit is not. A direct descendant of the SS-18, a missile designed to fly several tons of nuclear warheads from a Soviet silo to a capitalist target, the Zenit can catapult two to three times the tonnage out of the Earth's atmosphere as current versions of Delta or Ariane. Made of inexpensive Russian and Ukrainian components and assembled by dirt-cheap Yuzhmash technicians in Dnipropetrovsk, Ukraine's rocket costs about half as much as the Western competition. The down side is reliability. In 29 shots since 1985, Zenits have failed six times, according to Ukrainian Space Agency officials. (Western industry-watchers count two early test flights, putting the tally at eight failures out of 31 launches.) But at the end of the 20th century, all launch vehicles remain unpredictable, the Zenit's designer points out. "A failed launch is an unpleasant thing, but that is part of doing business in space," said Yuri Smetanin of the Yuzhnoye State Design Bureau. "It has been that way for everyone: for us, the Chinese, the Americans. No technology works perfectly all the time." A bluff, craggy-faced man, Smetanin has designed and built rockets for the last four decades. He and most experts agree that the world's most reliable launch vehicle is the U.S. space shuttle, which has worked 98 percent of the time. But the space shuttle is expensive - prohibitively so when it comes to launching satellites. Rockets are a better choice for the thrifty satellite launch shopper. American and French rockets function about 95 percent of the time, but they're not the cheapest on the market. That claim belongs to Zenit, Ukrainian Space Agency officials say. Which Globalstar understood perfectly well when it chose Zenit to launch birds 5 through 16 two months ago. The launch, which cost an estimated $32 million, would have set a record for placing the largest number of satellites into space on a single rocket.
Big Bang Theories The Sept. 9 mission failed spectacularly, scattering about $190 million worth of super-high-tech gear across the Altai mountains of central Siberia. The loss was insured, but industry analysts say the cost of insuring a commercial Zenit-2 launch will be much dearer as a result of the crash. A Russian-Ukrainian commission investigating the accident decided a computer glitch was the cause. The Zenit's on-board computer failed to recognize a millisecond shutdown of the rocket's primary and secondary communications frequencies as temporary, the commission found. The software concluded the Zenit was no longer talking to ground control and, as programmed, cut the engines. Assigning blame was complicated. The computer was built in Ukraine but some of its circuitry was Russian. About 40 percent of Zenit's parts are Ukrainian; 60 percent are Russian. The rocket was assembled in Dnipropetrovsk. The report studiously avoided finger-pointing, but Smetanin felt the heat. "Before that launch, no one knew Professor Smetanin was the 'Father of the Zenit,'" Smetanin said. "But the day after the launch, everyone knew." For the 74-year-old scientist, on-the-job stress levels have been rising for the last 18 months. On May 20, 1997, a Zenit with a Russian Tselina-2 communications satellite aboard exploded shortly before second-stage ignition. But two months later, a Zenit flawlessly orbited six birds for Israeli and European customers. "That was an extremely important shot," Negoda said. "That was our very first commercial mission, and it was absolutely successful." Unfortunately, next came the September 1998 Globalstar launch, which wasn't. Out of 15 launches since 1990, Zenits have failed six times - twice the official 20 percent failure rate. Only one of the last three missions was successful. Yuzhmash specialists realize a successful December shot is essential. "Our reputation is on the line," Smetanin said. "It has to work." The U.S. aerospace giant Boeing will also be watching to see how far the next Zenit gets. The Seattle-based firm is the lead company in Sea Launch, an ambitious $1.5 billion project that combines the disciplines of rocketry and off-shore drilling. Sea Launch plans to launch satellites from a souped-up off-shore drilling rig set down in an equatorial region of the Pacific Ocean. The location will take advantage of the Earth's gravity field to slingshot heavier payloads into orbit more economically than from land-based launch pads. Norway's Kvaerner Shipping Company built the platform and ships to carry the rockets and their payloads. Russia's Energia and Ukraine's Yuzhmash and Yuzhnoye design bureau are jointly building the Zenit-3, a new three-stage vehicle to be transported in segments and assembled at the platform. Yuzhmash and the design bureau Yuzhnoye own 15 percent of the venture. Boeing owns 40 percent, Kvaerner Maritime owns 20 percent and Russia's Energia owns 25 percent. Hughes Aerospace, PanAmSat and Loral Space Systems are all slotted for multiple launches. But delays have dogged the program. While Ukrainian and Russian officials argued about customs duties on rocket parts, the U.S. State Department slapped a $10 million fine on Boeing for not following bureaucratic procedures meant to insure that sensitive American rocket technologies are kept secret. The first Sea Launch liftoff was pushed back from October 1998 to March 1999. Then, after the September Zenit-2 crash, Boeing announced the first launch would be a test. News reports said PanAmSat, which was to place its satellites on the first Zenit-3, now wants to see a successful launch first. "We will have an inert payload aboard," Negoda said. "That will show customers what we can do." Meanwhile, PanAmSat announced last month its next two satellites will go with France's Ariane.
A Bigger Brother Americans and Europeans aren't the only ones offering to launch satellites for those wary of Ukrainian rockets. Russia's gigantic Proton competes directly with Zenit, in many ways outmatching it. Now built in cooperation with America's Lockheed, Protons have flown more often than any other booster on the planet - 259 times since 1965. Over the years Protons have glitched 15 percent of the time, a slightly better record than the Zenit's. As Russian and Ukrainian rocket scientists get paid about the same and the rockets use many similar components, the cost of a Proton satellite launch is roughly analogous to that of a Zenit launch. On June 18, 1997, a Proton successfully sent seven Iridium satellites into orbit. Two more successful Proton-Iridium launches followed on Sept. 14, 1997, and April 7, 1998. Not that Protons, or the men who launch them, are perfect. In 1990 a forgotten rag led to a crash; in 1993 contaminated fuel brought down a rocket. On Dec. 24, 1997, a Proton third-stage engine failed, leaving an AsiaSat satellite in a loopy orbit. But low cost, large payloads and 21 Iridium satellites in orbit to its credit give Proton a firm position in the satellite launch market. For the Ukrainians to compete, they must demonstrate that they can keep up with the Russians. To date, Ukraine has not been able to do that. Globalstar says it still plans to use Zenit next March to launch 12 satellites, assuming the December launch goes well. Globalstar's contract with Yuzhmash gives it a free launch in compensation for the failed one in September. In the meantime, Globalstar has moved forward planned launches on Russian Soyuz rockets. The Soyuz is a smaller rocket comparable to the Delta or Ariane but with a somewhat lower price tag. "Everyone will be watching Baikonur this December to see what happens," Smetanin said. "Especially Globalstar." |
