Fires can be destructive or healthy for a landscape—often both. Fires have grown larger and more destructive in recent years, though, thanks to human activity, climate change, and a host of other factors. Satellite data helps us to map and monitor fire activity, but the study of post-fire plant life using remote sensing data goes further than fire mapping.

For our third and final episode of Eyes on Earth from the September launch of Landsat 9, we hear from Virginia Norwood. She blazed a trail for women in remote sensing in the 1960s and 70s while working for Hughes Aircraft, a contractor for NASA.

The newly launched Landsat 9 experienced a once-in-a-mission lifetime event where its orbit was directly below Landsat 8 for an “underfly.” For several days in the middle of November, the pair of Earth-observing satellites flew together, collecting data at the same time for the same sites and requiring simultaneous downlinking to global ground station antennas.

Hundreds of scientists, officials, international representatives, and others witnessed the launch of Landsat 9 on September 27, 2021, from a handful of viewing sites around Santa Barbara County, California.

Landsat 9 launched into space on September 27th, 2021. The "first light" images arrived on October 31st. On that day the satellite captured: algal blooms in Lake Erie, the glaciers of the Himalayas, bush fires in Australia's Eucalypt Woodlands, coastal communities on the Florida panhandle, and deserts, mountains and mesas across the Navajo Nation.

The volcanic activity of Kilauea continues on the island of Hawaii. The latest eruption began within Halema'uma'u Crater on September 29. The previous eruption just ended in May 2021. Before that, major lava flows covered the eastern tip of Hawaii's Big Island in 2018. This latest eruption included vigorous fountaining up to 50-60m high.

Landsat 9 launched into orbit from Vandenberg Space Force Base on Monday, September 27, 2021, to carry on the legacy of a nearly 50-year record of continuous Earth observation that began in 1972. The days leading up to the event saw guests from around the world descend upon Santa Barbara County in California to watch the historic event take place.

Landsat satellites acquire useful data on wildfires around the world. Their near infrared and shortwave infrared imaging allows for detection and mapping of fire, smoke, and burn scars often in remote areas.
In California: the Dixie Fire near Lake Almanor and the Caldor Fire near Lake Tahoe.

The launch of Landsat 9 in September of 2021 represents a milestone for a joint USGS/NASA program that stretches back nearly 50 years. Landsat 9 will continue the legacy of unbroken, repeat Earth observations and contribute to our understanding of a changing planet.

The Caldor fire in California started on August 14, 2021 and quickly spread in high winds.
The fire continues to expand toward the Lake Tahoe area as residents evacuate.
This image was captured on August 21, the 8th day.
Landsat 8's near infrared and shortwave infrared bands reveal active fire, burn scars, and smoke.

The Great Lakes represent roughly 20% of the surface freshwater in the world and 90% in the United States. The Great Lakes Basin supports more than 30 million people in the U.S. and Canada and 3,500 plant and animal species. The region faces threats that range from climate change and invasive species to pollution and development.

The Dixie Fire has become the largest single fire in California's recorded history. State fire officials don't list it at the top, however. The record is held by the massive August Complex fire of 2020 which burned over one million acres. The term "complex" is used when multiple fires in the same area ignite separately.

Mapping land cover in the United States in the present isn’t a simple job, but satellites like Landsat make it possible. Mapping conditions in the pre-satellite era, which the LANDFIRE program does through its Biophysical Settings (BpS) GIS data products, is a far trickier proposition.

Urban heat islands occur in areas containing more impervious surfaces and fewer natural environments. The day and night surface temperature is higher in urban heat islands than in surrounding areas. During heat waves, this can lead to greater numbers of heat-related illnesses and deaths.

One of the most cratered landscapes on Earth is part of the Nevada Desert called Yucca Flat. Landsat 8's near-infrared and short wave infrared imaging shows the pockmarked surface perhaps more reminiscent of other planetary bodies than Earth.

The National Land Cover Database, or NLCD, was the first and remains the most well-known set of satellite-based land cover mapping products released by EROS. It sorts the each 30-by-30-meter plot of land in the United States into a land cover class, such as cropland, pasture, high-intensity developed, deciduous forest, and the like.
