The Hubble Space Telescope is slipping faster as solar activity climbs, and there’s still no approved plan to boost its orbit. A new plot tracking Hubble’s altitude shows the telescope descending more quickly in recent years, a sign that the aging observatory needs a lift soon to avoid a premature end of science operations. With no mission approved yet to raise its altitude, the window to keep Hubble productive is shrinking, making this a critical moment for planning and funding in space science
