NASA’s biggest headline this week is the successful launch of the TRACERS mission—a pair of satellites designed to help scientists understand how solar wind interacts with Earth’s magnetic field and triggers the kind of space weather that can disrupt power grids, GPS, and even astronaut safety. Joseph Westlake, NASA’s solar physics director, emphasized the mission’s direct benefit to everyday life, saying, “What we will learn from TRACERS is critical for the understanding and eventually the predicting of how energy from our sun impacts the Earth… It’s going to help us keep our way of life safe here on Earth.” This is not just science for science’s sake—TRACERS aims to give American citizens, utilities, airlines, and businesses better warning and protection from solar storms that could cause blackouts or communication outages.

But the news from NASA this week isn’t all clear skies and celebration. The agency is facing significant uncertainty after a White House budget proposal recommended canceling 41 active space missions and slashing nearly half of NASA’s science funding, a move that could lead to the shutdown of spacecraft still making discoveries and cut a third of agency jobs. Science advocates are calling this a potential “extinction-level event” for U.S. space exploration, warning that missions years or decades in the making may be lost. There’s still time for Congress to act, and citizen pressure is ramping up as supporters are urged to contact lawmakers and advocate for continued funding.

In related leadership news, there’s still no official word on a new permanent NASA Administrator after the White House withdrew the nomination of Jared Isaacman. The leadership vacuum comes as the Senate continues work on the One Big Beautiful Bill Act, a massive spending bill that is still working its way through Congress and may yet affect space funding down the line.

Amid these challenges, NASA’s international collaborations remain strong. Senegal just joined the Artemis Accords, furthering international commitments to peaceful and cooperative exploration of space. Meanwhile, the Crew-11 mission is preparing for launch to the International Space Station, and NASA astronauts Anne McClain and Nichole Ayers shared their excitement about the latest space station experiments and investigations, now building on years of progress in robotics, life sciences, and satellite servicing.

Looking ahead, listeners should watch for the July 31 launch of Crew-11 and the July 30 lift-off of the NISAR mission in partnership with India. There’s also a reminder that next week, a plane-sized asteroid will pass harmlessly by Earth, part of NASA’s ongoing efforts to monitor near-Earth objects and keep the public informed—media relations specialist Ian J. O’Neill underscores there’s no risk here, adding, “If there was a threat, you would hear from us.”

For more information or to advocate for space missions, listeners can check out updates on NASA’s own website, follow space advocacy groups like The Planetary Society, and most importantly, reach out to their representatives if they care about the future of American space science.
