NASA’s ECOSTRESS observes Apple Fire in California from Space

August 5, 2020 |

Pasadena, CA – NASA’s Ecosystem Spaceborne Thermal Radiometer Experiment on International Space Station (ECOSTRESS) captured a birds-eye view of the vast Apple fire raging in Southern California.

The wildfire began on the evening of Friday, July 31st, after two smaller fires merged and rapidly grew in the hot conditions in Riverside County, east of Los Angeles, prompting the evacuation of thousands of residents. Air temperatures have soared past 100 degrees Fahrenheit (38 degrees Celsius), stressing the vegetation and turning the area into a tinderbox. By Monday, the wildfire had exploded to over 26,000 acres.

NASA’s ECOSTRESS takes images of Amazon Fires

August 30, 2019 |

Pasadena, CA – NASA’s Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) captured imagery of fires in the Amazon regions of Brazil and Bolivia on Aug. 23, 2019.

The red areas in the images – in eastern Bolivia and northern Brazil – are where surface temperatures exceeded the maximum measurable temperature of the instrument’s sensor (approximately 220 degrees Fahrenheit, or 104 degrees Celsius), highlighting the burning areas along the fire fronts.

NASA lists Four Uses for ECOSTRESS measurements

July 2, 2018 |

Washington, D.C. – NASA’s Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) is designed to study how plants respond to heat and water stress by measuring the temperature of Earth’s vegetation at all times of day with an accuracy of a few tenths of a degree.

Unusual heat can be a warning sign of important changes and concerns in many fields of research besides botany. Here are four other areas where ECOSTRESS’s precise temperature measurements could make a difference.

ECOSTRESS’s precise temperature measurements could be helpful for other things besides studying plants’ heat stress, such as spotting new volcanic fissures and hotspots during an eruption. (USGS)

NASA’s ECOSTRESS instrument on it’s way to International Space Station

June 30, 2018 |

NASA’s Jet Propulsion Laboratory

Pasadena, CA – An Earth science instrument built by NASA’s Jet Propulsion Laboratory in Pasadena, California, and experiments investigating cellular biology and artificial intelligence, are among the research heading to the International Space Station following Friday’s launch of a NASA-contracted SpaceX Dragon spacecraft at 4:42am CDT.

Dragon lifted off on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida with more than 5,900 pounds of research, equipment, cargo and supplies that will support dozens of investigations aboard the space station.

About nine minutes and 31 seconds after launching from Cape Canaveral Air Force Station in Florida on June 29th, 2018, the SpaceX Dragon spacecraft carrying JPL’s ECOSTRESS mission separates from the second-stage engine.

NASA’s ECOSTRESS instrument on International Space Station to study Plant Water usage

June 20, 2018 |

NASA’s Jet Propulsion Laboratory

Pasadena, CA – Doctors learn a lot about their patients’ health by taking their temperature. An elevated temperature, or fever, can be a sign of illness. The same goes for plants, but their temperatures on a global scale are harder to measure than the temperatures of individual people.

That’s about to change, thanks to a new NASA instrument that soon will be installed on the International Space Station called ECOSTRESS, or ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station. ECOSTRESS will measure the temperature of plants from space. This will enable researchers to determine plant water use and to study how drought conditions affect plant health.

ECOSTRESS will measure the temperature of plants from space. Scientists will be able to use that temperature data to better understand how much water plants need and how they respond to water shortages. (USDA)

NASA using new Technology to observe Carbon in Earth’s Atmosphere

June 2, 2018 |

NASA’s Jet Propulsion Laboratory

Pasadena, CA – It’s a scientific conundrum with huge implications for our future: How will our planet react to the increasing levels of carbon dioxide in the atmosphere?

That seemingly simple question is particularly tricky because carbon — an essential building block for life on Earth — does not stay in one place or take only one form. Carbon in its many forms, both from natural and human-caused sources, moves within and among the atmosphere, the ocean and land as our living planet breathes. To track and inventory carbon and unravel the many intricate processes that cause it to morph across the planet is an epic challenge.

And that’s where NASA comes in.

NASA’s latest carbon-observing space mission is the Orbiting Carbon Observatory-2, which is making unprecedented global measurements of carbon dioxide levels in the atmosphere. (NASA-JPL/Caltech)

NASA developing ECOSTRESS instrument to analyze plant reactions to heat and water stress

October 28, 2014 |

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

Pasadena, CA – A new space-based instrument to study how effectively plants use water is being developed at NASA’s Jet Propulsion Laboratory, Pasadena, California. The instrument, called the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS), will monitor one of the most basic processes in living plants: the loss of water through the tiny pores in leaves.

When people lose water through their pores, the process is called sweating. The related process in plants is known as transpiration. Because water that evaporates from soil around plants also affects the amount of water that plants can use, ECOSTRESS will measure combined evaporation and transpiration, known as evapotranspiration.
