On March 11, 2026, geologists confirmed what some had suspected for years: a structure buried beneath the North Sea is a genuine asteroid impact crater. High-energy impact minerals in the rock samples settled the debate. Silverpit is real. An asteroid hit there, millions of years ago, and we only figured that out recently because we were looking at the ground, not the sky.
That is the part that should bother you.
NASA currently tracks roughly 30,000 near-Earth objects. About 95% of the large ones, the kilometer-plus civilization-enders, are catalogued. That sounds reassuring until you ask about the mid-size range: objects between 140 meters and 1 kilometer. Those are the ones that could level a city, trigger a regional catastrophe, or, if they hit water, send a tsunami across an ocean basin. Detection coverage there is thin. The teams doing this work are not failing; they are underfunded.
The Telescope That Changes the Math
NEO Surveyor is NASA's answer. An infrared space telescope designed to find mid-size threats that ground-based observatories miss, it can boost detection of objects in that dangerous middle range by roughly 10 times compared to current capability. Launch is scheduled for around 2028. NASA's FY2027 planetary defense budget request is $278 million, which covers NEO Surveyor development and operations. For context, that is less than 4% of NASA's total science budget, competing against programs like Mars Sample Return, which carries an estimated $11 billion price tag.
I will grant the skeptics one fair point: Silverpit is ancient history. An impact millions of years old does not tell us anything about what is inbound next Tuesday. The 2024 YR4 scare resolved cleanly in March 2026 when NASA confirmed it will not hit the Moon in 2032. The system worked.
But "the system worked" on a known object. The problem is the objects we have not found yet. Silverpit was not in any catalog. It was under the ocean floor. The lesson from that crater is not that ancient impacts happen; it is that detection has always lagged behind reality, and we keep discovering that lag after the fact.
What the Engineers Are Actually Asking For
The DART mission in 2022 proved we can move an asteroid. The Hera mission in 2024 followed up to measure exactly how well. The deflection side of planetary defense is in genuinely good shape. The detection side is where the gap lives, and NEO Surveyor closes it. The engineers at JPL and the teams building the instrument have done their part. The telescope design exists. The launch window exists. What does not yet exist is a locked FY2027 appropriation.
Congress will finalize FY2027 spending by October 2026. That is the deadline that actually matters here, not the crater confirmation date, not the YR4 resolution. Six months for the planetary defense community to make the case that $278 million is not a luxury line item.
Silverpit gives them a concrete argument. An asteroid hit near England hard enough to leave a crater 3 kilometers wide, and humanity did not know about it until scientists drilled into the seafloor and found shocked quartz. We got lucky that one happened millions of years ago. NEO Surveyor is how we stop relying on luck.
Fund the telescope. The engineering is done. The only remaining variable is whether Congress treats planetary defense like the infrastructure problem it actually is.
