NASA Adds SpaceX's Starship To Launch Services Program Fleet

Despite recent test failures, NASA has added SpaceX's Starship to its Launch Services Program contract, allowing it to compete for future science missions once it achieves a successful orbital flight. Florida Today reports: NASA announced the addition Friday to its current launch provider contract with SpaceX, which covers the Falcon 9 and Falcon Heavy. This opens the possibility of Starship flying future NASA science missions -- that is once Starship reaches a successful orbital flight. "NASA has awarded SpaceX of Starbase, Texas, a modification under the NASA Launch Services (NLS) II contract to add Starship to their existing Falcon 9 and Falcon Heavy launch service offerings," NASA's statement reads. Th announcement is simply an onboarding of Starship as an option, as the contract runs through 2032. However, SpaceX is under pressure to get Starship operational by next year as the company plans not only to send an uncrewed Starship to Mars by late 2026, but the NASA Artemis III moon landing is fast approaching. Should it remain the plan with the current administration, Starship will act as a human lander for NASA's Artemis III crew. "The NLS II contracts are multiple award, indefinite-delivery/indefinite-quantity, with an ordering period through June 2030 and an overall period of performance through December 2032. The contracts include an on-ramp provision that provides an opportunity annually for new launch service providers to add their launch service on an NLS II contract and compete for future missions and allows existing contractors to introduce launch services not currently on their NLS II contracts," NASA's statement reads.

NASA Considers Eliminating Its Headquarters in Washington D.C.

NASA is considering "closing its headquarters and scattering responsibilities among the states," reports Politico, citing two people familiar with the plan. "The proposal could affect up to 2,500 jobs and redistribute critical functions, including who manages space exploration and organizes major science missions." While much of the day-to-day work occurs at NASA's 10 centers, the Washington office plays a strategic role in lobbying for the agency's priorities in Congress, ensuring the White House supports its agenda and partnering with foreign countries on critical space projects. Some of the headquarter's offices might remain in Washington, the people said, but it's not clear which ones those would be or who would keep their jobs... One of the biggest fallouts is the damage it could do to coordination among NASA leadership on pressing issues... It would also limit cooperation with international partners on space, which is often done through embassies in Washington. NASA works with foreign partners on a range of projects, including the International Space Station and returning to the moon. The European Space Agency, for example, plans to provide modules for Gateway, a lunar space station that is central to NASA's Artemis program to land American astronauts back on the moon... The agency also helps coordinate support from foreign nations for the Artemis accords, which set goals for transparency and data sharing — and help create a level of trust in an unregulated part of the universe. But the reallocation could have some benefits. Such a move would bring headquarters employees closer to the processes they manage. And it would give legislative liaison staff a chance to interact with lawmakers in their districts. "You're probably getting a lot more time with [lawmakers] at the local center or hosting events in the state or district," said Tom Culligan, a longtime space lobbyist,, the space industry lobbyist.

NASA, Yale, and Stanford Scientists Consider 'Scientific Exile'

An anonymous reader quotes a report from 404 Media: Last week, Aix Marseille University, France's largest university, invited American scientists who believe their work is at risk of being censored by Donald Trump administration's anti-science policies to continue their research in France. Today, the university announced that it is already seeing great interest from scientists at NASA, Yale, Stanford, and other American schools and government agencies, and that it wants to expand the program to other schools and European countries to absorb all the researchers who want to leave the United States. "We are witnessing a new brain drain," Eric Berton, Aix Marseille University's president, said in a press release. "We will do everything in our power to help as many scientists as possible continue their research. However, we cannot meet all demands on our own. The Ministry of Education and Research is fully supporting and assisting us in this effort, which is intended to expand at both national and European levels." The press release from the university claims that researchers from Stanford, Yale, NASA, the National Institute of Health, George Washington University, "and about 15 other prestigious institutions," are now considering "scientific exile." More than 40 American scientists have expressed interest in the program, it said. Their key research areas are "health (LGBT+ medicine, epidemiology, infectious diseases, inequalities, immunology, etc.), environment and climate change (natural disaster management, greenhouse gases, social impact, artificial intelligence), humanities and social sciences (communication, psychology, history, cultural heritage), astrophysics." "The current Executive Orders have led to a termination of one of my research grants. While it was not a lot of money, it was a high profile, large national study," one researcher who has reached out to Aix Marseille University in order to take advantage of the program told me. 404 Media granted the researcher anonymity because speaking about the program might jeopardize their current position at a leading American university. "While I have not had to lay off staff as a result of that particular cancellation, I will have to lay off staff if additional projects are terminated. Everything I focus on is now a banned word." The program, called "Safe Place for Science," initially will fund 15 researchers with 15 million Euros. Aix Marseille University says that it is already working closely with the regional government and France's Chamber of Commerce and Industry "to facilitate the arrival of these scientists and their families in the region, offering support with employment, housing, school access, transportation, and visas." "We are doing what is necessary to provide them with the best living environment. We are ready to welcome them and will make them true children of the country!" Renaud Muselier, President of the Regional Council of Provence-Alpes-Cote d'Azur, said in a statement.
