NASA’s Expensive Pen, Soviet Pencils? Separate Development from Purchases
A familiar story contrasts NASA’s costly space pen with Soviet pencils. Separate who developed it, who tested it and who bought and used the product.
First, what is the space-pen story?
Spacecraft crews need tools for recording procedures and experiments. Fisher’s Space Pen uses pressure to move ink towards the tip. A familiar story says NASA spent heavily developing it while the Soviets simply used pencils.
NASA rejects the claim of millions in taxpayer-funded development. Fisher’s own account describes investing its own funds, while NASA contributed through testing and development support. Collapsing the developer and the tester/customer into one role changes the account.
The tools do not form a fixed American-pen versus Soviet-pencil split either. Early pencil use and later pen use belong to different periods. We will separate the initial development commitment, product purchase payments and users.
Does a team buying a pen mean it also paid all the development costs?
Pencils were part of the story
Fisher’s company history describes early American and Soviet crews using pencils. Read this as the manufacturer’s account, not as evidence that each country always used just one kind of instrument.
NASA’s 2021 explanation says broken pencil leads could float away and pose hazards to people and sensitive electronics. The choice between pencils and pens involved more than a joke contrasting a complicated tool with a simple one.
Separate Fisher’s development from NASA’s testing
NASA’s 2021 article describes Paul Fisher’s existing work on a pressurised pen and the contribution of NASA’s interest and tests. Fisher’s company account says he invested his own money. We do not establish an exact development total here.
NASA’s Spinoff 1986 also describes Fisher’s invention passing tests against NASA requirements. Rejecting the costly NASA-development story does not make NASA’s testing contribution or every associated activity cost disappear.
Initial development resources and product payments are different items
Invented manufacturer
Resources spent at the start of development
40 tokens
A record of the manufacturer’s initial commitment
Customer Team A
Team A’s product payment
4 tokens
2 units × 2 tokens
Product purchase payment only
Customer Team B
Team B’s product payment
6 tokens
3 units × 2 tokens
Product purchase payment only
More customers do not erase the separate initial-development record.
Customer Team A
Customer Team B
Later records include users in both programmes
NASA and Fisher identify Apollo 7 in 1968 as the pen’s first use in space. NASA’s 2021 article says cosmonauts have also used the pens since 1969.
The 1986 NASA record says the Soviet Union purchased the pens for cosmonaut use. A product used in both programmes complicates the fixed contrast of Americans using only pens and Soviets using only pencils.
Activity 1: change only the order quantity
An invented manufacturer initially committed 40 resource tokens to development. Team A buys products for 2 tokens each. Changing its order from 2 units to 6 changes Team A’s product payment from 4 tokens to 12.
The record of the initial 40-token development commitment stays fixed. We are separating that earlier input from the payment for the current order. Team A’s card shows its product purchase payment, not all of Team A’s costs.
- Prototype testing in Fisher’s account
Fisher’s company history describes sending prototypes to NASA in 1965 for testing. This remains attributed to the manufacturer.
- Space-pen use on Apollo 7
The mission NASA and Fisher identify as the pen’s first use in space.
- Cosmonauts also use the pen
The start year given in NASA’s 2021 account, distinct from a fixed pen-versus-pencil division.
Activity 2: connect a second customer
Next, connect Team B’s order to the same manufacturer. Buying 3 products adds another product-and-payment route. Both teams using the product does not change who initially committed development resources.
This does not mean sales cannot recover development costs. The model calculates neither later cash balances, cost recovery nor profit. It separates customer purchase payments from resources initially committed during development.
Keep the role and period with the claim
Reading NASA’s accounts alongside the manufacturer’s history helps keep development, testing, purchase and use distinct. Attribute the private-funding account to the company while retaining NASA’s testing contribution and later use in both programmes.
Rather than choosing which country was cleverer, ask whose payment is being described and which tool was used at which time. Fictional tokens illustrate that distinction; they do not establish historical amounts.
Separate the buyer from the initial development commitment
Increase an order and connect another customer while checking product payments separately from the resources spent at the start.
Compare orders and developmentSources and scope
Based on NASA’s 2021 explanation, its preserved Spinoff 1986 record and Fisher’s company histories. Institutional records and an interested manufacturer’s account remain distinct. No exact development total, historical unit price or order quantity is established here.

Text, pen icons and transaction diagrams are original. No product photographs, institutional logos, contracts, invoices or source scans are used. Fictional quantities and tokens are not historical amounts, and a product purchase payment is not a customer’s total cost. The model calculates no development-cost recovery, sales income or profit.
