NASA has invented new stopwatch which can measure a billionth fraction of a second. This cutting-edge watch will help them to record exact height of sea ice, glaciers, forests and other surfaces on this planet.

This special stopwatch is made for its ice, cloud and elevation satellite -1 (ICESAT -1). NASA will launch this satellite in 2018. It will use 6 green laser beams to measure elevation.

This stopwatch is really very amazing due to its precise measurement. NASA engineers can calculate the distance between the satellite and below the earth easily. Further, these record will provide the exact measurements of the planet’s surface.

The deputy project scientist, Tom added, light travels much faster, So, if you want to measure a little centimeter, you should have an excellent clock. This watch is capable of providing the exact data.

ICESAT-2 would not able measure height beyond 500 feet even if its watch work to a highly accurate millionth of a second. Roughly you can say, scientist won’t be able to tell the top of the five-floor house from the bottom.

In order to reach the required precision level, the scientist had to invent and build their own clocks known as ATLAS. ATLAS sends the beams of laser light to the earth and then note how long it takes to each photon to reappearance.

Time accuracy plays a key role in measuring exact heights. Without this, you won’t be able to get the distance within two inches. Even a minor mistake in data may lead to a disaster.

As per the reports, this stopwatch contains various parts itself for proper time recording. Like a GPS receiver which signals every second – a coarse watch which tells time for the satellite.
