NASA and JAXA's groundbreaking collaboration to study Earth's ice sheets using green lasers #NASA #JAXA #ICESat2 #GreenLaser #ClimateChange #PolarRegions NASA and JAXA's groundbreaking collaboration to study Earth's ice sheets using green lasers NASA has recently collaborated with the Japanese space agency JAXA to conduct a groundbreaking study on Earth's ice sheets . They have used a green laser technology to measure the ice elevation and study the changes that have occurred in the ice sheets over the years. This collaboration is part of NASA's Ice, Cloud and land Elevation Satellite-2 (ICESat-2) mission. The green laser technology is known for its precision and accuracy in measuring the height of the ice sheets. It has a wavelength of 532 nanometers , which is better suited for this type of measurement than the previous technology used, which had a wavelength of 1064 nanometers. The green laser technology also has a higher measurement rate, which allows for a ...
