NASA's Hubble Space Telescope was launched on April 24, 1990, and has already been staring at the distant universe for 3 and a half years.In recent years, however, a number of failures have been caused by a series of breakdowns, and on October 23, a problem that the synchronous communication between the control device and the observation device does not work on October 23, NASA on the 25th is the entire space telescope.We are taking measures to drop to safe mode.
Hubble space telescope, which is located higher than ISS, is exposed to strong cosmic rays on a daily basis, and may occasionally have a fine trouble, such as when the device is activated by a high -energy particles collision.However, in the case of a phenomenon where the cause is unknown, the operation team requires close attention.In order to be able to survive this system as much as possible and make as many observations as possible, we will restart each part of the device one by one while avoiding rapid consumption and temperature changes, and restart the whole.increase.
The engineer succeeded in restarting ACS (high -performance cameras for sweeping observation) on November 7.This device is a new device added to Hubble in 2002, and if the operation team resumes scientific observations with this camera and can use it for a while and use it normally, another device related to this device.I plan to restart and test.
At the time of the Hubble Space Telescope was launched, the space shuttle was still active, and this school bus -sized observation machine, which had been planned only for 10 years, was visited five times, and maintenance and renovation were applied.I have extended that life.However, the last site maintenance was implemented in May 2009, and all troubles were performed due to the retirement of the space shuttle, and all troubles were performed from the ground.
Hubble is still contributing to important observation, research, and new discoveries, but once the device breaks down, it will no longer be able to repair that part.
The operation team is struggling to restore this trouble.But that difficult effort may be open soon.NASA plans to launch a James Webb Space Telescope on December 18, one month later.This next -generation space telescope looks at the universe with a different wavelength (infrared), which is a different wavelength (infrared), which mainly observes visible light, but to observe distant phenomena, such as the birth of the first generation of stars in the universe.It is expected to contribute to many important discoveries in the future.
Hubble has managed to continue his activities despite being completely disabled, but I would like to expect a little further steps until the next time the baton is handed over.
