📌 Quick Summary (TL;DR): Deep Space
- 🌍 Origin: A fantastic modern cross bred by American tomato breeder Jason Haynes. It was named in honor of the NASA experimental space probe program.
- 🌿 Plant Habit: Indeterminate. Depending on growing conditions (outdoors vs. greenhouse), it can stay relatively compact at around 5 ft (1.5 m) or climb higher. Known for a very long fruiting season.
- 🍅 Fruit Characteristics: Stunning dark mahogany-brown plum tomatoes, often featuring a cute little pointed tip at the blossom end. Weight typically ranges from 3.2 to 4.2 oz (90–120 g) depending on how you prune the plant.
- ⏳ Maturity: Mid-season. Very heavy yielder.
- 👅 Flavor & Texture: Dense, firm, and super meaty with very few seeds. It has a rich, excellent flavor that makes it a top-tier choice for making dark sauces and canning.
Grower Reviews & Photos
The fruits are firm, meaty, and have very few seeds. They have a classic paste shape, weighing from 4.2 oz (120 g) and up. Awesome for canning. Heavy producer.
This is a newer cross, named after the “Deep Space” experimental automated space probe.

Tanya, mine grew to about 5 ft (1.5 m). Not super tall, but incredibly productive. The photo just shows the very first fruits pulled from a single plant.
Deep Space
A totally gorgeous variety 👍, tall, super productive 🙌, meaty, and tastes great. Mine weighed up to 3.2 oz (90 g) when grown in the greenhouse and pruned to multiple stems. If you stick to just 2 stems, they’ll get bigger. Beautiful dark brown color with a little pointed tip. Produces over a very long season.

Svetikk mentions a great tip for managing fruit size here! If you let an indeterminate tomato develop multiple main stems (often called “multi-stemming” or letting suckers grow out), the plant will produce more tomatoes, but they will generally be smaller. If you aggressively prune the suckers and keep the plant to just 1 or 2 main leaders, the plant focuses its energy into fewer, much larger fruits.
