Rank 50 in NASA Heritage Collector documents Stardust as the Discovery Program mission that returned solid cometary material to Earth for laboratory analysis — the first such sample return since Apollo. Launched on Delta II on 7 February 1999, the 385 kg JPL spacecraft flew through Comet Wild 2's coma in January 2004, capturing particles in a silica aerogel grid while imaging the nucleus and jet structures. The sample return capsule parachuted into Utah's Test and Training Range on 15 January 2006, delivering grains that revealed comet formation chemistry and interstellar dust tracks embedded alongside Wild 2 material. An extended NExT mission later flew by Comet Tempel 1, linking Stardust to the Deep Impact era. Wallimilist renders reentry fireball, Wild 2 nucleus, Delta II ascent, and aerogel inset exactly as the master PNG dictates — 2006 watermark, STARDUST title, and curator copy on primitive solar-system building blocks.
