* Initial Cost: The Hubble Space Telescope project was a massive undertaking. The initial cost in the 1970s and 80s (when it was built and launched) was around $1.5 billion (in 1990 dollars). That would be significantly more in today's currency.
* Ongoing Costs: Hubble requires regular servicing missions, upgrades, and ongoing operation. These costs are substantial, but are spread out over its entire lifetime.
* Unquantifiable Benefits: Hubble's scientific contributions are immeasurable. It's discovered new planets, studied black holes, and expanded our understanding of the universe. This scientific value is impossible to put a price tag on.
Therefore, focusing on the initial cost alone doesn't fully represent the true "price" of Hubble. Its impact and the ongoing investment have made it an incredibly valuable scientific tool.
