Jpl Red Logo — 4 museum-grade prints in this palette. GRACE transformed Earth science from snapshot measurements to continuous mass-balance monitoring — the mission whose maps appeared in IPCC reports, drought emergency briefings, and newspaper graphics explaining why California wells ran dry. GRACE-FO's laser ranging interferometer tested next-generation link technology for future gravity missions. InSight delivered the first confirmed marsquakes and a direct measurement of the Martian core radius, answering questions about planetary formation that orbiters alone could not resolve. Its MarCO CubeSat relays proved small satellites could support flagship landings. NuSTAR proved that hard X-ray astronomy could move beyond coded-aperture imaging to true focusing optics — a breakthrough that opened supernova element mapping, black hole spin measurement, and solar flare microphysics. The mission's first-light image of Cassiopeia A revealed titanium-44 emission, directly tracing the radioactive ashes of the explosion that created the remnant.
