Declaration of dissent, which warns that science and safety are at risk, joins similar documents from staff at the EPA and the NIH

‘We dissent’: NASA staff declare opposition to Trump cuts

More than 280 NASA employees past and present, including at least 4 astronauts, have signed a declaration of opposition to the many drastic changes that the administration of US President Donald Trump is working to enact. The declaration also urges the acting head of NASA not to make the unprecedented budget cuts Trump has proposed.

“The last six months have seen rapid and wasteful changes which have undermined our mission and caused catastrophic impacts on NASA’s workforce,” reads the employees’ letter to interim administrator Sean Duffy. It argues that Trump’s changes threaten human safety, scientific progress and global leadership at NASA.

The Voyager Declaration joins similar protest documents by employees at other US federal agencies, including the National Institutes of Health (NIH) and the Environmental Protection Agency (EPA). The appeals stem from Trump’s sweeping campaign to overhaul the federal government, which has led to mass firings of workers and the proposal of steep cuts to agency budgets.

The declaration is “about getting our dissent out to the public and saying, hey — this is what’s happening at NASA, and this is not OK”, says Ella Kaplan, who has signed the document. Kaplan works on a contract basis as a website administrator at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and was speaking on her own behalf and not that of her employer or of NASA.

Kaplan says she does not expect Duffy to read the document or to care much about it if he does. When Duffy ran for a seat in the US Congress more than a decade ago, he released a campaign advertisement that featured him wearing lumberjack clothing and saying he would bring his axe to “topple the big spending in Washington”.

NASA did not immediately respond to Nature’s request for comment.

Staff exodus

The Voyager Declaration, named after the twin NASA spacecraft that are exploring interstellar space, protests against staffing cuts at the agency and Trump’s proposed cuts to science funding and other NASA budgets. The agency has fired some employees and pressured others to leave, resulting in the loss of more than 2,600 of the 17,000-plus NASA employees, according to news platform Politico. At least US$118 million in NASA grants has been cancelled outright, and the White House has proposed slashing nearly half of the agency’s science budget for next year.
