49 years ago, on April 24, 1970 21 when 35 minutes, our country launchs a center to launch the first satellite successfully in wine spring satellite -- east is red, initiated China of spaceflight history epochal, make our country becomes afterwards revive, the 5th independent development is intercurrent the country that shoots man-made world satellite, improved the international position of our country greatly, carry greatly brace up the confidence of the people of the whole country. When day of spaceflight of the 4th China comes, we uncover secret east red a few stories with emissive little-known backside of a satellite and detail, the hardships that experiences person of older generation spaceflight to do poineering work jointly and not easy.
● checks: The history that breakdown brings about is sorry
After undertaking rocket of 6 hair intermediate range launchs an experiment, 2 emissive field enter the arena of world spaceflight formally.
On September 3, 1969, of two newest development " east wind 4 " -- what say later namely " long march 1 " carrier rocket secret transfers 7 tests workshop. These two rockets are be developed on foundation of rocket of intermediate range of east wind series and become, be used technically at launching Oriental Gong Weixing. "East wind 4 " in long-range rocket is comprised by rocket of two class liquid, rocket of a paragraph of solid increased on its. If these two rockets launch an experiment to gain a success, it is mature already to will mean the conditional line of business that launchs Oriental Gong Weixing.
"East wind 4 " in last centuries 60 time manufacture the rocket, all sorts of interference affected development plan and quality inevitably. Just arrive at the rocket of emissive field, breakdown of the problem in checking is ceaseless, removing trouble everyday almost. Qian Xuesen guides everybody one by one platoon checks rocket breakdown hidden trouble.
On November 16, 1969 afternoon at 6 o'clock, head hair " east wind 4 " the rocket breaks through heavy obstruct, bringing the be on the tiptoe of expectation that develops personnel, fleet towards booked target and go. At the beginning, radar system and film altazimuth are uninterrupted dog target, follow a rocket to fly off all the time emissive field is measured control area. Emissive personnel has begun to cheer, prepare to celebrate. Be in right now, fall the area transmits a message suddenly, the rocket is missing from radar, optics dogs to also cannot find a cause.
This message sprinkled a cold water to everybody. "East wind 4 " the cannon-shot of the rocket can amount to 5000 kilometers, once out of control, fly off very likely territory boundary. This is in in those days below the sort of nervous international environment, consequence cans be imagined.
Technical personnel is analysing the point of fall with likely rocket nervously, search personnel is empty-handed. Money learns Sen Wen dispatch to arrive measure accuse a computer room, manage analytic rocket placement personally. He watched the scene measure after dominating data, resolutely conclude: The rocket falls along parabola in place of 600 much kilometers, gave out relatively exact placement position. According to Qian Xuesen give directions, search plane discovered rocket wreckage very quickly in Xinjiang churchyard.
Breakdown reason just departs plug contact is undesirable, bring about a rocket depart did not succeed between class.
Head hair " east wind 4 " the rocket launchs an experiment to end in order to fail so.
On January 30, 1970, the 2nd hair " east wind 4 " the rocket blasts off achieve complete success, "East is red 1 " the program on emissive immediately platoon of the satellite. Everybody is blasting off to be about to greet the first orbiter of our country and excited when, unavoidable also have a regret. Because be discharged hammer and tongs in us,check " east wind 4 " when the breakdown of the rocket, japan had been driven in front of us to launch the first their satellite successfully, become the state of the 4th emissive orbiter.
