Got questions about NASA astronaut glasses? We answer the most common ones about using them as an astronaut coffee mug, their size, care, and who they suit.
Quick answer
The NASA Astronaut Glasses are a 7-ounce double-walled set of two, best treated as a small espresso or dessert glass rather than a full-size astronaut coffee mug. They suit space fans who want a display-worthy sipping glass and are willing to hand-wash them.
What the 7-ounce size means for daily use
At 7 ounces, these glasses hold about half the volume of a standard 12- to 16-ounce coffee mug. That makes them a poor match for a large morning brew but a good fit for espresso, cortado, tea, or a small dessert. If you want a space themed coffee cup for a full cup of coffee, plan to refill or choose a larger vessel.
The double-walled construction is the reason the small size works: it keeps the outside comfortable to hold without adding a handle, so the glass stays compact and easy to store.
Why the iridescent finish changes how you clean them
The radiant iridescent color is a surface finish, not a printed decal, so it can dull if scrubbed with abrasive sponges or exposed to harsh dishwasher detergents. Treat these as hand-wash items to keep the glow intact. This is a real trade-off: you get a striking look, but you give up the convenience of tossing them in the dishwasher.
Who these glasses are not for
Skip them if you need a large-capacity mug for commuting, if you routinely microwave your drinks, or if you want a handled mug for hot coffee. The set is also a poor choice for households with young children who might knock over a glass without a handle. For those cases, a sturdy ceramic space-themed mug is the safer pick.
NASA astronaut glasses FAQ
- Can I use NASA astronaut glasses as an astronaut coffee mug?
- Yes, but only for small servings. At 7 ounces, they hold roughly half a standard mug, so they work best for espresso, cortado, or tea rather than a full 12-ounce coffee.
- Are they dishwasher safe?
- Hand-wash them to protect the iridescent finish. Abrasive sponges and harsh dishwasher detergents can dull the coating over time. Rinse immediately after use to avoid staining.
- Can I put hot drinks in them?
- Double-walled glass is designed for hot and cold drinks, but sudden temperature changes can stress glass. Warm the glass with tap water before pouring boiling liquid.
- Are they microwave safe?
- The catalog does not state microwave safety, so do not microwave them. Use a separate mug for reheating.
- How many glasses do I get?
- The set includes two 7-ounce glasses, which makes it easy to share a small coffee or dessert with someone.
- Who are these glasses best for?
- Space fans who want a display-worthy, officially licensed NASA item and who mostly drink small servings. They are less practical for large coffees or households with young children.
