![]() It hardly needs to be said that in 1972, digital anything was pretty innovative, let alone high-performance digital sensors in orbit. “But Hughes convinced NASA to put another instrument on the payload that was more experimental: the Multi-Spectrum Scanner. “Landsat 1 launched in 1972 - it carried two instruments, one was the Return Beam Vidicon, and it was kind of like a TV camera, it took analog data,” Irons said. ![]() It’s fitting that for a project that would redefine Earth imaging, its very first satellite was both innovative and historically significant. ![]() Irons told the story of Landsat from the beginning, both what he took part in himself and the lore he’s absorbed over the years. I talked with Jim Irons, who has worked at NASA since 1978 and on Landsat since 1992. It was slowly drifting along the Antarctica for more than a year, but its melting has accelerated now and the iceberg is heading for its eventual demise, the outlet further said.A schematic sketch of Landsat-1. Iceberg 76A is the largest among these pieces. It is the biggest chunk of the Rhode Island-size A-76, the previous largest iceberg in the world, which broke off from the western side of the Ronne Ice Shelf in Antarctica in May 2021 and later split into three pieces: 76A, 76B, and 76C, Live Science reported. ![]() ![]() In October 2022, Terra satellite spotted the berg drifting into the turbulent Drake Passage between Antarctica and South America. Meet Antarctic iceberg A-76A - the biggest remaining piece of what was once the largest floating iceberg. In a new satellite image revealed by American space agency NASA, Antarctic iceberg A-76A, the biggest remaining piece of what was once the largest iceberg, could be soon heading towards its demise.Īs per the US National Ice Centre, the iceberg is 135 kilometres long and 26 kilometers wide (measured in June 2021) - an area equal to about twice the size of London. ![]()
