Did nasa use whale oil?
Quick Answer
Yes, NASA used sperm whale oil (spermaceti) as a lubricant in some spacecraft and instruments through the 1970s. Whale oil's unique properties — stability at extreme temperatures and pressure, low volatility, and excellent lubricating qualities — made it valuable for precision instruments. NASA stopped using whale oil after the 1972 Marine Mammal Protection Act and developed synthetic alternatives.

The Short Answer
Yes, NASA did use whale oil — specifically spermaceti oil from sperm whales — as a lubricant in varies by species (krill, fish, squid) spacecraft components and precision instruments through the 1970s. The unique properties of sperm whale oil made it exceptionally valuable for space applications: it remained stable at extreme temperatures, didn’t evaporate in vacuum conditions, and provided superior lubrication under high pressure. Following the 1972 Marine Mammal Protection Act, NASA developed synthetic alternatives.

Frequently Asked Questions
Did NASA know whale oil came from endangered whales?
NASA’s use of whale oil occurred before sperm whales were classified as endangered (1970) and before the Marine Mammal Protection Act (1972). At the time, whale products were commonly used in industry, and the full extent of whale population decline wasn’t widely understood. Once protections were enacted, NASA transitioned to alternatives.
Is whale oil still used anywhere today?
Very rarely and illegally in most countries. Japan, Norway, and Iceland continue limited whaling, but commercial whale oil production is essentially extinct. Some traditional Indigenous communities have exemptions for subsistence use. The vast majority of applications now use synthetic or plant-based alternatives.
Was the Hubble Space Telescope lubricated with whale oil?
No. While whale oil was initially considered for Hubble’s gyroscopes, the telescope was launched in 1990 — well after whale oil was phased out. Hubble uses synthetic lubricants. The confusion may stem from early planning documents that mentioned whale oil as an option.
How much whale oil did NASA actually use?
Exact quantities aren’t publicly documented, but NASA’s usage was relatively small compared to industrial applications. Spacecraft require only small amounts of lubricant. The significance is more about the unique properties whale oil provided rather than the volume consumed.
Could we ever need whale oil again?
Extremely unlikely. Modern synthetic lubricants equal or exceed whale oil’s performance for virtually all applications. The extensive research triggered by the whale oil ban produced superior alternatives. There is no technical justification for returning to whale products.
Conservation Connection
| Statistic | Details |
|---|---|
| Sperm whales killed (20th century) | ~700,000 |
| Current population | ~300,000-450,000 |
| IUCN Status | Vulnerable |
| Recovery | Slow but occurring |
The transition away from whale oil in industries like aerospace contributed to the protection and gradual recovery of sperm whale populations. Learn more about whale conservation in [are blue whales endangered](/faq/are-blue-whales-endangered/).
Fun Fact
The search for whale oil alternatives led to the commercial development of the jojoba plant, which was virtually unknown before the 1970s. Today, jojoba oil is a multi-billion dollar industry used in cosmetics, lubricants, and pharmaceuticals — a direct result of the ban on whale products. The whales’ protection inadvertently created an entirely new agricultural industry!

People Also Ask
why are sperm whales called sperm whales?
Sperm whales are named after spermaceti, a waxy substance found in their enormous heads. Early whalers mistakenly believed this substance was the whale's sperm, but it is actually an organ used for echolocation and buoyancy control.
is a whale a mammal?
Yes, a whale is a mammal, not a fish. Whales possess all five key characteristics of mammals: they breathe air through lungs, are warm-blooded (endothermic), give birth to live young, produce milk to nurse their calves, and have hair or bristles at some point in their lives.
what do sperm whales eat?
Sperm whales primarily eat medium to large-sized squid, including the elusive giant and colossal squid. They consume approximately 3% of their body weight daily, which equals about 2,000 pounds (907 kg) of food. While cephalopods make up the bulk of their diet, they also prey on sharks, skates, and deep-sea fish.
Are blue whales endangered??
Blue whales are currently listed as endangered with approximately 200,000-300,000 individuals remaining in the wild.
