| 正面铭文 | SAMOA 2015 $5 FA`AVAE I LE ATUA SAMOA (Translation: Samoa $5 Samoa is founded on God) |
| 背面描述 | The entire reverse field is occupied by a full-color reproduction of an iconic Hubble Space Telescope photograph, depicting the Westerlund 2 star cluster set within the Carina Nebula, rendered in vivid hues of blue, pink, orange, and gold against a deep black star-field. A dense cluster of brilliant blue-white stars dominates the center of the composition, surrounded by billowing clouds of luminous nebular gas and dust. The Hubble Space Telescope 25th Anniversary logo, rendered in white, appears in the upper left of the field alongside the legend 'HUBBLE SPACE TELESCOPE 25TH ANNIVERSARY' in two lines. |

NASA's Hubble Space Telescope, launched in 1990, was initially crippled by a spherical aberration in its primary mirror — a polishing error of just 2.2 micrometers rendered its first images blurred. The corrective optics mission, STS-61, flew in December 1993 and remains one of the most technically complex spacewalks ever performed. By 2015, when this coin was struck, Hubble had completed over a million observations and was deep into its fourth servicing mission's extended science program.
Samoa entered the commemorative silver market aggressively in the early 2010s, issuing numerous collector pieces tied to science and space themes through the New Zealand Mint.
