Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation – The accompanying unaudited condensed consolidated financial statements have been prepared by Astrotech Corporation in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. Operating results for the nine months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending June 30, 2019. These financial statements should be read in conjunction with the financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2018.
Accounting Pronouncements	Accounting Pronouncements – In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. In July 2018, the FASB issued ASU 2018-11, “Leases (Topic 842): Targeted Improvements” (“ASU 2018-11”) and ASU 2018-10, “Codification Improvements to Topic 842, Leases” (“ASU 2018-10”). ASU 2018-11 provides for an additional optional adoption method of ASU 2016-02, allowing for the application of the new standard as of the adoption date and recognizes a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption. ASU 2018-10 provides corrections and updates to the previously issued codification regarding Topic 842. Various areas of the codification were impacted from the update. The two standards follow the effective dates of ASU 2016-02. The Company’s population of leases consists of two property leases of 17,560 square feet expiring in April 2020 and 5,219 square feet expiring in December 2023, and a few office equipment leases. The Company has engaged a third-party to assist in assessing and implementing the new standard, including classification of leases, identifying lease and non-lease components, discount rates, and the practical expedients that are available under the guidance. The Company expects to complete the assessment and impact of adopting the new standard by the end of fiscal year 2019. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities. For assets held at amortized cost basis, ASU 2016-13 eliminates the probable initial recognition threshold in current generally accepted accounting standards, and, instead, requires an entity to reflect its current estimate of all expected credit losses. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial assets to present the net amount expected to be collected. For available-for-sale debt securities, credit losses should be measured in a manner similar to current generally accepted accounting standards; however, ASU 2016-13 will require that credit losses be presented as an allowance rather than as a write-down. ASU 2016-13 affects entities holding financial assets and net investment in leases that are not accounted for at fair value through net income. This amendment affects loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the impact the adoption of this standard will have on its financial statements.

The TRACER 1000 is currently undergoing regulatory testing with both the Transportation Security Administration (“TSA”) and European Civil Aviation Conference (“ECAC”) as certification by either agency is necessary to sell the TRACER 1000 to the airport market. On June 19, 2018, the Company announced that the TRACER 1000 had entered the ECAC Common Evaluation Process (“CEP”) to obtain certification in Europe. On December 12, 2018, the Company announced that the TRACER 1000 passed the ECAC CEP tests for airport checkpoint screening of passengers. On January 9, 2019, the Company subsequently announced that the TRACER 1000 passed the CEP tests for airport cargo screening. Finally, on February 21, 2019, the Company announced that 1^st Detect received ECAC certification for both passenger and cargo screening for the TRACER 1000, and the Company can now begin selling its product internationally. In addition, on March 27, 2018, the Company announced that the TRACER 1000 was accepted into TSA’s Air Cargo Screening Technology Qualification Test (“ACSQT”) and, on April 4, 2018, the Company announced that the TRACER 1000 began testing with TSA for passenger screening at airports. Both programs are currently progressing as expected. With TSA and ECAC having two of the most rigorous technology review programs for Explosive Trace Detectors (“ETDs”) in the world, we believe certification by either program is a significant endorsement that customers in other vertical markets consider when procuring ETDs. There is no assurance that any of the further steps detailed above will be achieved or that our technology will be approved by any of the programs.

In addition, Astral employs Artificial Intelligence to automatically extend the color gamut and enhance the dynamic range to be viewed in 4K and/or high-dynamic range (“HDR”), collectively known as ultra-high definition (“UHD”). Although we believe Astral has developed valuable technology fortified by patents and trade secrets, the potential market has not evolved as quickly as anticipated. Due to funding constraints, the Company’s main focus remains on the 1^st Detect opportunity. Consequently, headcount and expenditures at Astral are minimized and new development is exclusively focused on strategic initiatives that would facilitate the realization of Astral’s value.

The Company had no unrecognized tax benefit for the three and nine months ended March 31, 2019 and 2018. Loss carryovers are generally subject to modification by tax authorities until three years after they have been utilized; as such, the Company is subject to examination for the fiscal years ended 2000 through present for federal purposes and fiscal years ended 2006 through present for state purposes. The reason for this extended examination period is due to the utilization of the loss carryovers generated by the sale of our Astrotech Space Operations business unit in fiscal year 2015.
