NASA faces a proposed $6 billion agency-wide funding cut by the Trump administration, including a 47% reduction of science missions and activities.

The National Aeronautics and Space Administration (NASA) is expected to cut at least 20 per cent of its workforce, in a second major staff cut to hit the US space agency under the Trump administration. This leaves the employee count at around 14,000.

Nearly 300 current and former NASA employees — including astronauts, engineers and scientists — have signed the "Voyager Declaration," a formal statement raising alarm over recent actions and steep budget cuts proposed by the Trump administration.
