IN MAY, about 20 miles [30 km] from the town of Truth or Consequences, New Mexico, a fire broke out. The Black Fire quickly exploded, increased, and consumed large parts of the country’s southwestern region. Later that month, its growth was reflected in images from a satellite known as Landsat 8. The photos, which capture infrared light and visibility, show burnt and hot spots and smoke.

Landsat 8, as you can imagine, is the eighth orbiter built into a system called Landsat, a set of satellites collecting data and photographing EarthEarth since 1972. Landsat’s 50-year reserve helps us understand how everything came to be. Glaciers in urban areas have changed — and continue to change.

Landsat was not the first scientific satellite; Before the start of the program, scientists were accustomed to using spacecraft to monitor the weather. But the idea that man could also use orbiters to understand Earth’sEarth’s conditions came later, after photographs taken in the atmosphere of Mercury and Gemini showed the Planet’s location and resources. The power of this theory led William Pecora, a former director of the United States Geological Survey, to ask himself: What if scientists put something permanent on Earth’sEarth’s orbit?

Pecora presented an opinion to the United States Secretary of State in the mid-1960s, persuading the secretary to announce his intention to launch such a program. But according to NASA history, that was a real political stunt. It meant angering good people and accelerating progress in the development of satellites at NASA, which had the skills and knowledge to build them. “The Interior Ministry’s surprise announcement attracted a lot of attention in Washington, sparking political protests from NASA and security agencies, not one of whom was looking for another competitor in the world observation business,” read Landsat’s Enduring Legacy, a recent press release. Landsat Legacy project team. A day later, the piece continues, Pecora’s wife recalled that “the White House was ready to kill him, the Pentagon was ready to kill him, and the State Department was ready to kill him.”

Critics’ objections to the proclamation included — but were not limited to — the following: Airlines may do the same thing. The civilian spacecraft may reveal a lot more about defense-focused satellite capabilities. Also, some countries do not always like it when you fly high above them and take pictures.

NASA was involved in the controversy. The space agency hosted a workshop to discuss the use of this technology, such as identifying plant species and the title of agricultural diseases, and adopted the idea. In 1972, NASA launched the Earth Resources Technology Satellite program, later renamed “Landsat.” “Understanding and being able to view the Earth from outer space was just a revelation,” said Jim Irons. They began working with satellite data about 1976 and later became a scientist for the Landsat 8 project and a deputy scientist for the Landsat 7. project.
