South Korea’s Ministry of Science and ICT sent a national alert that “some debris from a falling US Nasa satellite sparks may crash close the Korean peninsula” at almost lunchtime.
South Koreans, utilized to getting mobile phone alerts warning of earthquakes or Covid outbreaks, obtained a more unusual notification Monday morning, cautioning of threat from above.
The country’s Ministry of Science and ICT sent a national alert that some debris from a falling US satellite may crash close to the Korean peninsula” at almost lunchtime. Please be aware when moving out during that time.
The ministry later told in a statement that the retired spacecraft – NASA’s Earth Radiation Budget Satellite was considered to have passed over the Korean Peninsula, and no particular damage has been declared so far.
The US space agency told last week that the 5,400-pound (2,450-kilo) satellite would probably re-enter the earth’s atmosphere on Sunday or Monday.
While most of the closely 40-year-old spacecraft was anticipated to burn up upon re-entry into Earth’s atmosphere, some elements were expected to survive and crash to Earth. NASA had stated the risk of damage coming to anyone on the planet was “very quiet.”
South Korea, however, was taking no options and used its emergency broadcast system to transmit a message to the country’s mobile phones.
Most man-made space debris which drops to Earth poses little danger to humans, although some occasions, like the uncontrolled re-entry last year of rocket boosters utilized to launch a Chinese space station module, have prompted worries about the potential for ground strikes.
Q1. What occurs if the satellite falls?
Even if small chunks of satellites were handled to hit the ground, their shockwaves could cause considerable damage.
Q2. Can a satellite fall back to Earth?
Gravity combined with the satellite’s momentum from its launch into space caused the satellite to go into orbit above Earth, rather than falling back down to the ground.
Q3. How many dead satellites are in the sky?
While there are about 2,000 active satellites orbiting Earth at this point, there is also 3,000 dead ones littering space.
