Tracking Earth,
in plain English.
A small editing exercise on a NASA mission page — and a demonstration of what content strategy looks like when applied with restraint.
The NASA-ISRO SAR (NISAR) Mission will monitor changes in Earth's land, water, vegetation, and ice to better understand processes such as vegetation change, natural hazards, sea level variation, and groundwater movement. It will also support a host of societal benefits. NISAR will collect global observations of land and ice-covered regions every 12 days from both ascending and descending orbits, providing an average revisit time of about 6 days over a planned three-year mission. NISAR will observe Earth's land and ice-covered surfaces globally with 12-day regularity on ascending and descending passes, sampling Earth on average every 6 days for a baseline 3-year mission.
Earth's surface is always moving. NISAR is built to track it.
A joint mission of NASA and the Indian Space Research Organisation (ISRO), NISAR scans nearly every land and ice surface on the planet roughly once a week, detecting motion as small as a fraction of an inch. Its data will serve farmers, emergency responders, and communities near earthquake faults, volcanoes, deforestation zones, and rising coastlines by giving them time to anticipate change rather than only respond to it.
Over a planned three-year mission, NISAR will produce one of the most detailed pictures of our changing planet ever assembled.
