NASA Frames ESA’s LISA Mission as a 'Good Deal' Amid Partnership Tensions
NASA Administrator Jared Isaacman is redefining international space partnerships as 'good deals' requiring tangible contributions, a shift that has strained relations with the European Space Agency (ESA) over lunar programs. However, the Laser Interferometer Space Antenna (LISA) mission remains a key exception. NASA views its role in LISA as highly cost-effective, providing roughly one-third of the funding for 100% of the science data. While the Trump administration proposed canceling NASA’s participation, Congress restored funding for fiscal year 2026, signaling continued support. ESA is leading the mission, which aims to detect low-frequency gravitational waves using three spacecraft in a triangular formation, with a launch scheduled for around 2035.
