【俄罗斯联盟号火箭发射,遭受雷击仍成功升空】
2019年5月27日, 联盟2号航母在俄罗斯北部 Mirny 附近的普列西茨宇宙基地, 搭载了一颗全球导航卫星系统 (Glonass-m) 卫星。然而, 飞行10秒后, 升空的火箭被一道闪电击中。俄罗斯国防部在事发后报告说, 与飞船建立并保持了稳定的遥测连接。物理学家史密斯表示被闪电击中对火箭发射的威胁并不是特别大,这是一个已知的危险, 科学家在设计之初就会考虑这个影响因素。
Electrifying footage shows the moment Russian Soyuz rocket is struck by lightning during launch — and STILL manages to lift off successfully
Lightning struck ten seconds into the launch from northern Russia on May 27
The rocket had been carrying a replacement radio navigation satellite into orbit
Telemetry suggests that the Soyuz was hit on its nose and third-stage booster
Despite the lightning, the rocket successfully delivered its payload on schedule
Lightning struck a Russian Soyuz rocket just ten seconds into its thunderous journey up through the atmosphere, shocking footing reveals.

闪电
The electrical discharge hit the Soyuz both on its nose fairing and its third-stage booster segment, according to the spacecraft's on-board instruments.
Unimpeded by the strike, the carrier rocket continued into its planned low-earth orbit, where it delivered its payload of a radio-based navigation satellite.

Shock lightning bolt almost strikes Russian rocket as it launches
Lightning struck a Russian Soyuz rocket (pictured) just ten seconds into its thunderous journey up through the atmosphere, shocking footing reveals.
The Roscosmos Soyuz 2-1b rocket roared into the air from the Plesetsk Cosmodrome near Mirny, northern Russia, at 06:23 UTC (07:23 BST) on May 27, 2019.

The Soyuz 2 carrier launch, the first from the cosmodrome this year, was carrying a replacement GLONASS-M (Global Navigation Satellite System) satellite into orbit.
Ten seconds into the flight, however, the ascending rocket was hit by a bolt of lightning.
Roscosmos director Dmitry Rogozin posted a video of the launch, showing the shocking moment that the lightning struck, onto Twitter.
In the post, he congratulated the Russian space forces and scientists, adding that 'lightning is no hindrance for you.'
The rocket continued its 3.5 hour flight into a low-Earth orbit, where it proceeded to deliver its satellite payload on schedule.
'A stable telemetric connection [was] established and maintained with the spacecraft,' the Russian Ministry of Defense reported after the incident.
'The on-board systems of the GLONASS-M spacecraft are functioning normally.'

Instruments about the Soyuz rocket recorded data on the lightning strike, transmitting the information with its regular telemetry to the control centre at the cosmodrome on the ground.
'During the liftoff, lightning struck the nose fairing and the third stage of the carrier rocket,' an unidentified source in the Russian space industry told the Russian News Agency TASS.
‘The incident did not affect the operation of the carrier rocket’s systems, as Soyuz spacecraft are equipped with the protection mechanism against such phenomena,' the source added.

'While rather spectacular, being struck by lightning is not particularly threatening to a rocket launch,' UCL physicist Alan Smith told MailOnline.
'It's a known hazard, of course, and the outer shell of the rocket can cope with the electrical surge without affecting the interior,' Professor Smith added.
'Aircraft are often struck by lightning with no serious effect.
'The metal rocket skin creates a Faraday Cage around its interior, protecting it from harm.
'Of course there is always a chance that some critical sensor on the outside might be affected, but this has been considered.'

Lightning strikes on rockets might be rare, but they are not without precedent.
The Saturn V rocket that carried the Apollo 12 mission to the moon was struck twice by lightning during its ascent through the atmosphere on November 14, 1969.
The resulting power surge led to the command and service modules fuel cells and instrumentation being taken offline, and telemetry with NASA's mission control in Houston, Texas was disrupted.
Quick thinking from ground-based flight controller John Aaron and spacecraft systems engineer Alan Bean on board the rocket brought the command module's systems back online by switching to a backup power supply.
Fortunately, the lightning had caused no serious permanent damage and the mission carried on to the moon as intended.

发射
The weather on the day of the Apollo 12 launch had been cloudy, but not stormy — making the strikes themselves somewhat unexpected.
A NASA investigation into the incident later revealed that 'lightning can be triggered by the presence of the long electrical length created by the space vehicle and its exhaust plume in an electric field which would not otherwise have produced natural lightning.'
Nowadays, space agencies have extremely stringent weather guidelines for rocket launches and lightning protection built into both spacecraft and their launch pads.
NASA regulations, for example, prohibit rockets being fuelled if there is more than a 20 per cent chance that lightning may strike within five-miles of the launch site.
Electrical field activity around rocket centres are rigorously monitored.
Similarly, rocket launches are only permitted if no lightning or storm clouds have been observed within a 10-mile (16 km) radius of the rocket's flight path.
Launch pads are typically fitted out with lightning rods to prevent direct strikes to their rockets before launch.

'The weather is not an obstacle and we [the Space Force of Russia's Aerospace Forces] are all-weather troops,' cosmodrome chief Major-General Nikolai Nestechuk told RT.
Although the Soyuz rocket was carrying a civilian satellite, the Plesetsk cosmodrome is a Russian military facility.
'The launch was carried out in the normal mode,' Major-General Nestechuk added.
'This is yet more proof that lightning cannot damage our aerospace weapons.'
