About the company
Essential Space, Inc., doing business as Teaching Science & Technology Inc., is a veteran-owned small business based in Manitou Springs, Colorado, that provides specialized systems engineering, space systems, and leadership training to federal agencies as a prime contractor exclusively — the vendor operates entirely without subcontractors and competes across both full-and-open and small-business set-aside procurements.
Essential Space's capability portfolio centers on live instructor-led and virtual training delivery across systems engineering, model-based systems engineering (MBSE), space systems engineering, project management, digital engineering, and leadership and organizational development. The vendor's recent award examples include a $743,232 five-year virtual space systems engineering training delivery order placed by the Department of the Air Force Space Command Space and Missile Systems Center under Essential Space's GSA Multiple Award Schedule vehicle (ultimate completion May 31, 2028); a $109,550 firm-fixed-price Blanket Purchase Agreement call from Naval Sea Systems Command for a project accelerator workshop focused on leadership and team development methods (December 2024, completion September 30, 2025); a $108,454 purchase order from the NASA Shared Services Center for space launch and transportation systems live instructor-led training in Manitou Springs, Colorado (June 2026, completion September 17, 2026); and a $95,193 total small-business set-aside purchase order from NAVSEA for engineering training curriculum development (March 2023, completion September 30, 2023).
Essential Space's customer base is highly concentrated in space and defense agencies. The top five customer organizations by award count account for 51% of recent awards and include the NASA Shared Services Center (11 awards, $701 thousand combined potential value), NASA Johnson Space Center (9 awards, $193 thousand), the Department of the Navy Naval Sea Systems Command (5 awards, $605 thousand), and the Department of the Air Force Space Command Space and Missile Systems Center (5 awards, $280 thousand). When ranked by combined potential value, the GSA Federal Acquisition Service dominates at $12.7 million across 2 awards — reflecting Essential Space's seat on two GSA vehicles — followed by the Department of the Air Force and NASA Shared Services Center. The vendor holds positions on the GSA Professional Services Schedule (52 task orders, $4.5 million combined potential value) and the GSA Multiple Award Schedule (2 task orders, $764 thousand), and operates a single-award Blanket Purchase Agreement with NAVSEA running through June 2027 with a $240 thousand ceiling.
Activity has been sparse and volatile — one award in 2021, one in 2022, two in 2023, three in 2024, and one in 2026 — across a 25-year presence in the federal award footprint. Only two awards (combined potential value $852 thousand) reach ultimate completion inside the next twenty-four months, reducing near-term recompete exposure. The vendor has obligated $5.3 million across the portfolio, representing 28% of combined potential value, a signal that many training task orders remain unfunded or partially funded.
