Eighth Atlantis mission

6 m / sec to leave GRo orbital plane, both to achieve the level of separation. Out before the release of the satellite, Ross and Apt stay airtight cabin, but there is another vote of the cabin pressure to prepare for the deployment of GRO process of China's space needs Astronautics No. 8 of 1991 Eighth Flight Air Atlantis mission Ba i ~ R members to help. EVA lasted 4 hours 24 minutes. GRO release of about 40 minutes, the orbiter engine speed for 11 seconds, to 0.9 m / sec left the satellite, and after a orbiter at the top then the satellite to l1.1 km per lap speed to separate distance of 83.25 kilometers until the two tracks so far. GRO failed to open because the antenna may be due to the space shuttle during launch loose insulation material or other materials caused. 3 car test at 9:51 on April 8, the astronauts at the 2nd extra-vehicular activity, the left wall installed in the payload bay long 14. o4-meter track, the aim is to make manual, mechanical and electrical test of three compartments. Each of the three astronauts inside are tested. This is followed by 3 cars on the tracks mounted on a gondola. Speed of up to 1.35 meters / sec. Cars pulling each other to simulate the movement of large objects when the Apt test of motor cars, he found the car running smoothly, like a manual car on the same railway. In Section 3 on the inside, the astronauts turned by hand as the wheel-like rotating cabin automatic hand crank to generate electricity. In the car running,[link widoczny dla zalogowanych], the battery will replace the hand crank generator power. But if they have brakes, car will run more better. Other tests are on the arm, the first 2 boat outside activities lasted 6 hours and 11 minutes. April 9, the use of star tracker, the GRO satellite location for the target was to keep testing. Typically, between the use of manned spacecraft rendezvous radar. But NASA plans to use star tracker as an alternative method of intersection. A distance of 48.27 kilometers, the stars search to GRo detector in this flight, Atlantis away from the Soviet Mir space station 100 kilometers above the cross. U.S. astronauts and Soviet cosmonauts tried to contact by radio,[link widoczny dla zalogowanych], said that the United States to the Soviet cosmonaut crew Xin voice, but it was unclear whether the Soviet Union, the Americans heard the voice of April 10, as planned orbiter at Edwards Air Force should base land, but because of too much wind, the landing time was delayed. April l1 at 8:55, Atlantis at Edwards Air Force Base landing on runway 33. Control personnel and payloads, according to experts, the space shuttle Atlantis has made a number of secondary outcomes, including the Space Shuttle was the middle cabin materials testing, testing new equipment and technology practice of a secondary intersection . The flight lasted 7 days a success, as planned in mid-May GRO should begin its observations. (See the current photos of gamma-ray detector Cover) (Xu Xing) U.S. Space Station Freedom and the use of the construction cost will reach 118 billion U.S. dollars according to the U.S. General Accounting Office (GAo) said a recent report, NASA significantly underestimated a new dimension has been reduced total cost of Space Station Freedom. NASA and the GAO estimated the difference between the cost of up to 4O%. GAo that by 2000, the station will cost about 400 billion U.S. dollars, this cost starting from the end of 1996 stood rail spatial cost of the first 3 years. Space station design life of 30 years,[link widoczny dla zalogowanych], so it can use to 2027, GAO estimated Aug. 1991AerospaceChina dollars, to the 2027 date, in addition to the 40 billion U.S. dollars, but plus another 27 years of operating costs, the total cost of Space Station Freedom will reach 118 billion U.S. dollars. The NASA estimation, space station by 2000 to ask the cost of 300 billion U.S. dollars, the use of each year cost about 20 billion U.S. dollars, 2027 to date, the operating cost of 540 billion U.S. dollars, so the station's total cost of 84 billion The estimated dollar amount of this difference with the GAo 340 million. GAo that, NASA's space station did not the estimates of some components essential for the development and usage costs into account, such as,[link widoczny dla zalogowanych], GAo estimates included 15N20 billion rescue costs, NASA is no estimate of the expenditure also , NASA has also ignored the orbital maneuvering vehicle (oMV) and orbital Transfer Vehicle (oTv) of these essential and remote control robot vehicle (FTV) costs.
