WHY WAS THIS FUNDED?

NASA has legal authority and a congressional mandate to study Earth's environment and climate from space, and this mission falls under that broader Earth science program. The partnership with India's space agency also reflects U.S. government goals to conduct cooperative international science projects.

WHAT PUBLIC PROBLEM IS IT TRYING TO SOLVE?

Scientists and emergency managers need better data on how Earth's land surface is shifting, which affects earthquake preparedness, glacier and ice sheet melting, sea level rise, and the health of forests and wetlands. NISAR is designed to provide detailed, frequent radar measurements of these changes across the entire planet.

WHO BENEFITS?

Scientists, farmers, disaster response agencies, and coastal communities benefit from improved data on natural hazards and environmental changes. Workers at Caltech's Jet Propulsion Laboratory in California and partner contractors also benefit through employment on the project.

WHAT ARE THE RISKS?

Large, complex space missions frequently experience cost overruns and schedule delays, and a ten-year contract of this size requires strong oversight to ensure taxpayer money is spent effectively. Coordination with a foreign space agency also adds logistical and diplomatic complexity that could affect the project's timeline.

WHAT HAPPENS IF FUNDING IS REMOVED?

Cancelling this contract would likely end or severely delay the NISAR satellite mission, halting years of development work and damaging the U.S.-India space partnership. The loss of the satellite's data would leave gaps in scientists' ability to monitor natural hazards, land movement, and environmental changes globally.

ARGUMENTS FOR

• •NISAR would provide scientists with detailed global radar data every 12 days, greatly improving our ability to track earthquakes, floods, wildfires, and climate-related land changes that affect millions of people.
• •Sharing costs and technology with India's space agency makes the mission more affordable for U.S. taxpayers and strengthens a key international scientific and diplomatic relationship.
• •Earth observation data from missions like NISAR has practical uses in agriculture, infrastructure safety, and disaster response, meaning the investment can produce broad economic and public safety benefits.

ARGUMENTS AGAINST

• •At nearly $779 million over ten years, this is a very large commitment of public funds, and NASA space science projects have a history of cost growth beyond original budgets.
• •Some critics argue that international partnerships introduce dependency on foreign governments and add risk if political relationships or foreign agency priorities change over time.
• •Funding this mission means those dollars are not available for other NASA priorities, domestic infrastructure, or other public needs, raising questions about whether this is the best use of limited federal resources.
