NASA is currently transitioning its operational model to increase the frequency of robotic missions through the integration of commercial technologies and a restructuring of budgetary priorities.

NASA 目前正處於運作模式的轉型期，旨在透過整合商業技術及重新調整預算優先順序，來增加機器人任務的頻率。

The agency's current scientific trajectory is characterized by a stagnation in the volume of planetary missions relative to historical benchmarks, despite a science budget of $7.25 billion that remains consistent with inflation-adjusted levels from two decades prior. Under the leadership of Administrator Jared Isaacman, there has been a pronounced shift toward human lunar exploration, evidenced by the successful Artemis II mission and the subsequent prioritization of a lunar surface base over a lunar-orbiting station. Concurrently, the administration is advocating for a transition from bespoke, high-cost spacecraft to the utilization of commercial off-the-shelf (COTS) satellite buses. This strategy aims to replace infrequent, billion-dollar 'flagship' missions with a higher volume of lower-cost probes, potentially utilizing 'block buys' of commercial platforms to enhance the cadence of exploration.

該機構目前的科學發展軌跡，其特徵在於行星任務的數量相對於歷史基準處於停滯狀態，儘管 72.5 億美元的科學預算與二十年前經通貨膨脹調整後的水平持平。在局長 Jared Isaacman 的領導下，重心明顯轉向人類月球探索，Artemis II 任務的成功以及隨後將月球表面基地的優先權置於月球軌道站之上，均證明了這一點。同時，管理層正倡導從訂製的高成本太空船轉向利用商用現成 (COTS) 衛星平台。此策略旨在以大量低成本的探測器取代那些不頻繁且耗資十億美元的「旗艦」任務，並可能利用商業平台的「批量採購」來提升探索頻率。

Institutional constraints persist, however, as the most complex interstellar and deep-space objectives remain incompatible with low-cost commercial platforms. The agency's planetary science portfolio exhibits significant temporal gaps; for instance, the Discovery program has seen a marked decline in launch frequency since 2011, while the New Frontiers program faces budget overruns, as seen with the Dragonfly mission. To mitigate these constraints, NASA is exploring the application of artificial intelligence to reduce the operational costs of legacy missions and is streamlining the competitive selection process for new proposals. Parallel to these systemic shifts, the agency continues to execute high-priority projects, such as the NEO Surveyor and the Nancy Grace Roman Space Telescope, the latter of which has seen its launch window accelerated to as early as September 2026 through a synergy of public and private sector efforts.

然而，制度性限制依然存在，因為最複雜的星際與深太空目標仍與低成本商業平台不相容。該機構的行星科學組合呈現出顯著的時間間隙；例如，「發現號」計劃自 2011 年以來發射頻率明顯下降，而「新前沿」計劃則面臨預算超支，如 Dragonfly 任務所示。為了緩解這些限制，NASA 正在探索應用人工智能以降低舊有任務的運作成本，並簡化新提案的競爭篩選程序。在這些系統性轉變的同時，該機構繼續執行高優先級項目，例如 NEO Surveyor 和 Nancy Grace Roman 太空望遠鏡，後者透過公私部門的協同努力，將發射窗口提前至 2026 年 9 月。

NASA is attempting to reconcile ambitious deep-space scientific goals with fiscal constraints by leveraging commercial partnerships and optimizing mission management.
