Isaacman Defends Trump's Major Planned Cuts to NASA Budget
The Trump Administration released its plan for NASA's Fiscal Year 2027 budget on April 3rd, outlining 5.6 billion United States Dollars in cuts, equivalent ot twenty-three percent of the agency's budget, for the second year in a row.
Not long after the White House budget was released, NASA Administrator Jared Isaacman sent a letter to agency employees about it. In the letter he defended the cuts without calling them cuts, writing:
"I strongly support the President’s fiscal policies and mandate to drive efficiency. The President’s Budget provides Congress and the public with the vision and resources to carry out our mission. The requested funding levels are sufficient for NASA to meet the Nation’s high expectations and deliver on all mission priorities."
A few days later, Isaacman was on CNN and defended the budget again by drawing on international comparisons, saying:
"NASA's budget is greater than every other space agency across the world. NASA's science budget is greater than every other space agency combined across the world."
During Trump's cuts for Fiscal Year 2026, later restored by Congress, Acting NASA Administrator Sean Duffy was highly supportive of them with a similar line of messaging to Jared Isaacman.
Items on the cutting block
A short while after the White House released its broad strokes of the cuts, NASA shared the fine details. Some agency items on the Trump Administration's cutting block are:
- Earth Surface Mineral Dust Source Investigation
- Tropospheric Emissions: Monitoring of Pollution
- ECOsystem Spaceborne Thermal Radiometer
- Global Ecosystem Dynamics Investigation
- Surface Water and Ocean Topography
- Total Solar Irradiance Sensor-1
- Soil Moisture Active and Passive
- Global Precipitation Measurement
- ICESat-2
- Gravity Recovery and Climate Experiment Follow-On
- Polar Radiant Energy in the Far Infrared
- Neil Gehrels Swift Observatory
- Solar Data Center
- Space Physics Data Archive
- Community Coordinated Modeling Center
- Electrojet Zeeman Imaging Explorer
- Polarimeter to Unify the Corona and Heliosphere
- Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites
- Atmospheric Wave Experiment
- Sun Radio Interferometer Space Experiment
- Low Boom Flight Demonstrator
Most items related to the Space Launch System and the Orion spacecraft, which are used to send astronauts to the Moon, are also zeroed out by the Trump Administration, alongside lunar surface science experiments and activities, expecting Congress to allocate funding. Despite that, Administrator Isaacman claimed that only the efforts of the Trump Administration made the Artemis II mission possible, which is disingenuously false.
