Rocket Launch Countdown Sound Effect Free Download
Terry Chavarin
Fresh install of KSP2, booted up the game and built a rocket in the VAB. Music and UI sound effects worked fine throughout. When I went to launch my rocket, no sounds at all. No environment sounds, no countdown sounds, no launch sounds, and no rocket sounds. I pressed escape and the UI sounds were working. I reverted to the VAB and music and UI sounds were working fine as well. Relaunching the rocket from the VAB caused the sound to begin working again as expected, with countdown, UI and Rocket sounds.
India is a country with 1.4 billion people, yet, the voices of a few people remain etched in people's minds for eternity. Celebrities, politicians, sports personalities and even scientists are among this list. ISRO rocket launches are iconic events that bring the entire nation together and millions tune in to their TVs or devices to watch the live stream of the mission.
She was the voice behind ISRO's pre-launch countdown announcements and had last announced on July 30th, when the PSLV-C56 rocket lifted off carrying 7 Singaporean satellites, as part of a dedicated commercial mission. As part of the Range Operations Programme Office at the Satish Dhawan Space Centre, she had been making the countdown announcements for all launches, over the past six years or so, it is learnt. Aged in her fifties, she passed away on Saturday evening at a private hospital in Chennai, owing to a cardiac arrest. She had been unwell for a while.
For journalists like this author (who have been regularly reporting the Indian space programme and related launches from the spaceport), the voice of the ISRO scientists making the pre-launch and mission progress announcements are imprinted for eternity. As journalists stand atop the ISRO media centre terrace and report the launch mission, specifically the TV journalists tend to look into the camera and report the liftoff, as the rocket lifts off far away in the background. This is a moment of anxiety, as one does not have a direct view of the vehicle lifting off.
Owing to the professional responsibility of having to look straight into the blackness of the video camera lens and 'speak to the audience directly', TV journalists do not have the luxury of watching the vehicle lifting off (more than five kilometres away), behind their backs. It is the voice of the announcing officials that offer all updates on the countdown, help perfectly time the Piece-to-Camera recordings and understand the launch mission progress etc. Therefore, their voices are permanently imprinted and become a part of life and work.
Narrator: As the Atlas V rocket that would blast Perseverance off Earth was being assembled, the crane that hoists the heavy rocket parts into place experienced a fault that took several days to fix. The launch date slipped again because of concerns over potential contamination of a ground support line, and then a misbehaving liquid oxygen sensor line pushed the launch day back even more.
At several predetermined points during the launch countdown, NASA will pause the clock as part of standard procedure to give the ground teams time to resolve any unexpected issues that may crop up. At the end of these "built-in holds," the countdown clock will resume unless NASA encounters any technical glitches. [How to Watch NASA's Final Space Shuttle Launch]
At the T-minus 9 minute mark, the clock will typically enter a 45-minute hold. Before this point, the NASA test director will perform a launch readiness poll of the shuttle launch team. Weather forecasts for the Cape Canaveral area will also be checked to verify that the conditions meet the agency's criteria for a safe launch.
During the hold, NASA officials on consoles will be polled for their "go/no go" decisions. These technicians closely monitor computer displays and gauges that show the performance of the shuttle's systems at the launch pad.
After the T-minus 9 minute built-in hold, the countdown will resume. The Ground Launch Sequencer (GLS), which is an automated program that controls all activity during the final portion of the countdown, will assume automatic control of the countdown at the T-minus 9 minute mark. This program will continue to monitor the vehicle's parameters and will be able to halt the countdown if a problem is detected. The GLS is typically started at about the T-minus 45 minute mark.
At this point, the shuttle's commander will advise his or her crewmates to close the visors of their launch and entry suits. In these final minutes leading up to launch, the Ground Launch Sequencer is still in automatic control of the countdown.
Now, the sound suppression water system at the launch pad will be activated to protect the shuttle and its payloads from being damaged by the strong acoustical energy during liftoff.
Water is stored in massive tanks on the northeast side of the launch pad and is released just prior to the ignition of the shuttle's main engines. Nine seconds after liftoff, the water suppression system's peak flow rate is 900,000 gallons per minute.
The solid rocket boosters will be ignited, and the bolts that have secured the shuttle to the ground in the last six seconds of the countdown are explosively released, allowing the orbiter to rocket into the sky. Once this happens, we have liftoff!

She spent two years with Space.com, writing about rocket launches and covering NASA's final three space shuttle missions, before joining the Live Science team in 2013. A Canadian transplant, Denise has a bachelor's degree from the University of Toronto, and a master's degree in journalism from New York University. At NBC News, Denise covers general science and climate change.
During gameplay (especially during the launch sequence), players will receive (hear) a variety of Audio Cues, keeping them informed as to the status of their rocket or spacecraft and the progress of the maneuvers it performs. The man who voices these cues can be found in the credits.
On this episode, we find out about the Student Spaceflight Experiment Program. The program gets kids to design experiments with the goal of having their work loaded into a rocket and launched 400 kilometres up to the International Space Station. And Edmonton Public Schools is not about to miss that trip!
In architecture and engineering obviously wind and wind shear are important issues for tall buildings. I understand that weather is an important condition for the launch of rockets or the hundreds of shuttle launches.
During the STS-115 launch countdown a wind direction change occurred at 15,000 feet (15 ft/s tailwind to 10 ft/s headwind) over a period of roughly an hour. Since the first stage trajectory had been designed using the original winds, this resulted in a reduction in dynamic pressure margin. A special assessment was done using the L-1:10 winds measurement and dynamic pressure was predicted to be at 100.2% of the limit where 100.5% would have been a "no-go" call. None of the "wind change" rules had been violated. This analysis took place between T-39 and T-28 minutes - per the normal ascent preparation timeline, the final assessment of this regime had already been done.
Weather-related holds and scrubs are extremely common. There are strict rules about wind speed and cloud cover limits for launches, and often there's a window of an hour or less on a given day for a launch; if the weather doesn't cooperate through the launch window, they detank the rocket and try again the next day.
