Accounting Policies [Abstract] |
Consolidation, Policy [Policy Text Block] | Principles of Consolidation and Basis of Presentation The accompanying condensed consolidated financial statements of Astrotech Corporation and Subsidiaries (collectively the “Company”) have been prepared without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and disclosures required by accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. These condensed financial statements reflect all adjustments that, in the opinion of management, are necessary to present fairly the results of operations of the Company for the period presented. The results of operations for the three months ended September 30, 2025, are not necessarily indicative of the results that may be expected for any future period or the fiscal year ending June 30, 2026 and should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2025, filed with the SEC.
Segment Reporting, Policy [Policy Text Block] | Segment Information The accounting guidance on Segment Reporting establishes standards for reporting information regarding operating segments in annual financial statements and requires selected information of those segments to be presented in financial statements. Operating segments are identified as components of an enterprise for which separate discrete financial information is available for evaluation by the chief operating decision maker (the “CODM”), the Chief Executive Officer, in making decisions on how to allocate resources and assess performance. Net sales attributed to customers in the United States and foreign countries as of September 30, 2025, and June 30, 2025 were as follows:

New Accounting Pronouncements, Policy [Policy Text Block] | Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” which is intended to enhance the transparency and decision usefulness of income tax disclosures. The guidance addresses investor requests for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. The guidance is effective for annual periods beginning after December 15, 2024. We adopted this standard in fiscal year 2025 This pronouncement has not impacted the Company’s consolidated financial statements Recently Issued Accounting Standards Not Yet Adopted In November 2024, the FASB issued Accounting Standards Update 2024-03 "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40)" which requires that at each interim and annual reporting period an entity: 1. Disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization included in each relevant expense caption. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contains any of the listed expense categories. 2. Include certain amounts that are already required to be disclosed under current generally accepted accounting principles (GAAP) in the same disclosure as the other disaggregation requirements. 3. Disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. 4. Disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. These amendments are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027: either (1) prospectively to financial statements issued for reporting periods after the effective date of this Update or (2) retrospectively to any or all prior periods presented in the financial statements. The Company expects to enhance disclosures of expenses based on new requirements. In November 2024, the FASB also issued Accounting Standards Update 2024-04 "Debt - Debt with Conversion and Other Options (Subtopic 470-20) “Induced Conversions of Convertible Debt Instruments” to clarify the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. Under the amendments, to account for a settlement of a convertible debt instrument as an induced conversion, an inducement offer is required to provide the debt holder with, at a minimum, the consideration (in form and amount) issuable under the conversion privileges provided in the terms of the instrument. An entity should assess whether this criterion is satisfied as of the date the inducement offer is accepted by the holder. If, when applying this criterion, the convertible debt instrument had been exchanged or modified (without being deemed substantially different) within the one-year period leading up to the offer acceptance date, an entity should compare the terms provided in the inducement offer with the terms that existed one year before the offer acceptance date. The amendments in this Update also clarify that the induced conversion guidance applies to a convertible debt instrument that is not currently convertible as long as it had a substantive conversion feature as of both its issuance date and the date the inducement offer is accepted. The amendments are effective for all entities for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. The Company is examining the impact this pronouncement may have on the Company’s consolidated financial statements. Other accounting pronouncements issued but not yet effective are not believed by management to be relevant or to have a material impact on the Company’s present or future consolidated financial statements.
