InternationalLaunch of Ariane RocketPuts Europe in Space BusinessWith the second successful testlaunch of the European-built Arianerocket on June 19, it is now clear thatEurope is in the space business <strong>to</strong> stay.The Ariane rocket, a cooperativeeffort of the 11-member EuropeanSpace Agency (ESA), is an expendablerocket that will for the first time giveEurope the independent capability <strong>to</strong>launch satellites in<strong>to</strong> space.In a recent interview, Wilfred Mellors,direc<strong>to</strong>r of ESA's Washing<strong>to</strong>n,D.C., office, <strong>to</strong>ld <strong>Fusion</strong> that therewere three main ways in which thelaunch was significant."The overriding importance of thesuccessful launch," he stated, "is thatit proves that the modifications thatwere made after the second testlaunch failed last year were correct.The burn of the rocket was extremelysmooth."Second, this is the first time thatEurope has effected the launch of twosatellites with one vehicle." This isimportant for reasons of economics."Third," Mellors commented, "wenow have a geostationary meteorologicalsatellite over Europe that willbe working within a month. Meteorologistshave been waiting anxiouslyfor this satellite <strong>to</strong> go up, <strong>and</strong> wehope <strong>to</strong> get data starting in mid-August."Mellors explained that the UnitedStates had launched a weather satellitefor the Europeans in 1977, but theimager failed after two years, hamperingcontinuous weather forecastingfor the continent. Until now onlythe United States <strong>and</strong> Soviet Unionhave had reliable launch capabilities.The ArianeThe Ariane, which is being built forESA by Aerospatiale of France, is aliquid-fuel three-stage rocket, similar<strong>to</strong> the U.S. Delta <strong>and</strong> Centaur expendablerockets. ESA expects theAriane <strong>to</strong> be competitive with thecomparable U.S. rockets when it becomesoperational in 1982. It may alsobe competitive with the reusableSpace Shuttle for certain kinds of payloads.The Ariane's payload capacity isnow 3,749 pounds but second <strong>and</strong>third-generation Ariane rockets areplanned that will bring the capacityup <strong>to</strong> 5,324. Even with the currenttechnology, Ariane can put two satellitesin<strong>to</strong> geosynchronous orbitabove a spot on the Earth 16 minutesafter lif<strong>to</strong>ff.ESA has scheduled the last test flightfor Feb. 1982 <strong>and</strong> hopes <strong>to</strong> put thesystem in<strong>to</strong> operation immediatelyafter that.International CompetitionThe 6th <strong>to</strong> 23rd flights of the Arianescheduled through Dec. 1985 are alreadybooked solid. These launcheswill include ESA's Halley's Comet missionscheduled for 1985 <strong>and</strong> otherscientific missions. But the greatestinterest is coming from developingsec<strong>to</strong>r nations, which have previouslybeen dependent upon the U.S. spaceagency for satellite launches.A consortium of Arab nations hascontracted <strong>to</strong> launch two communi-ESA's Arianerocket.cations satellites—Arabsat 1 <strong>and</strong> 2—in1983 <strong>and</strong> 1984. The second satellitelaunched by the Ariane in June wasan Indian-built Apple communicationssatellite.Aerospatiale has set up a new companycalled Arianspace <strong>to</strong> marketspace on the Ariane, <strong>and</strong> on June 11the French company signed a memor<strong>and</strong>umof underst<strong>and</strong>ing withBoeing Aerospace in the United Statesfor joint marketing. Boeing is buildinga platform for the Ariane that willallow the multiple stacking <strong>and</strong> servicingof satellites.—Marsha FreemanMexico: Economic WarfareThreatens Oil-for TechnologySevere economic warfare hasthrown some obstacles in the way ofMexico's economic growth, makingit more difficult in the near term forMexico <strong>to</strong> achieve an "oil-for-technology"trade framework with theUnited States.In late May, a group of oil multinationalsled by Exxon began <strong>to</strong>pressure Mexico <strong>to</strong> slash its oil prices,justifying their dem<strong>and</strong>s by citing thetemporary world oil glut.At first, Jorge Diaz Serrano, direc<strong>to</strong>rof Petroleos Mexicanos, the nationaloil industry, acceded <strong>to</strong> the pressure,dropping Mexico's prices a full $4 perbarrel. But the Mexican economiccabinet, headed by President JoseLopez Portillo, charged that the actionwas "precipi<strong>to</strong>us," <strong>and</strong> in somethingof a political earthquake, Diaz Serranowas relieved of his duties June 7. OnJuly 1, the new Pemex direc<strong>to</strong>r, MoctezumaCid, announced that negotiationswere underway <strong>to</strong> raise theprice back up $2 per barrel.All-out oil warfare immediately began.Exxon canceled 175,000 barrelsOc<strong>to</strong>ber-November 1981 FUSION 47
