PSLV-C61成功取消了，但在第三階段的異常導致任務失敗。 ISRO承諾詳細分析

Sriharikota | 2025年5月18日，印度第101衛星任務在地球觀察衛星EOS-09未能實現其預期的軌道之後，週日遭受了重大挫折

India's 101st satellite mission suffered a setback on Sunday as the Earth Observation Satellite EOS-09 failed to achieve its intended orbit following launch aboard the Polar Satellite Launch Vehicle (PSLV-C61).

印度第101衛星任務在周日遭受了挫折，因為在Polar衛星發射車（PSLV-C61）上發射後，地球觀察衛星EOS-09未能實現其預期的軌道。

The launch from the Satish Dhawan Space Centre in Sriharikota began as planned, with ISRO confirming that performance was normal through the second stage. However, a critical issue during the third stage led to an anomaly, disrupting the mission's success.

Sriharikota的Satish Dhawan太空中心的發布開始按計劃進行，ISRO確認在第二階段的表現正常。但是，在第三階段的關鍵問題導致異常，破壞了任務的成功。

“Today’s PSLV-C61 performance was normal till the 2nd stage. Due to an observation in the 3rd stage, the mission could not be accomplished,” ISRO stated in a post on X.

ISRO在X上的一篇文章中說：“今天的PSLV-C61表現正常，直到第二階段。由於在第三階段進行了觀察，因此無法完成任務。”

"There will be a technical review to assess the third stage failure, and findings will be released accordingly," the agency added.

該機構補充說：“將進行技術審查來評估第三階段的失敗，並將相應地發布發現。”

This was the 63rd flight of the PSLV and the 27th with its XL configuration, continuing its legacy as ISRO's workhorse launcher.

這是PSLV的第63次飛行和27號XL配置，繼續作為ISRO的Workhorse Launcher的遺產。

EOS-09, equipped with C-band synthetic aperture radar (SAR), was designed to operate in a Sun Synchronous Polar Orbit (SSPO), offering all-weather, day-and-night imaging capabilities.

EOS-09配備了C波段合成孔徑雷達（SAR），旨在在太陽同步極性軌道（SSPO）中運行，提供全天候，白天和晚上的成像功能。

The payloads are part of a broader constellation that provides India with critical environmental and security monitoring systems, scientist W Selvamurthy explained.

科學家W Selvamurthy解釋說，有效載荷是一個更廣泛的星座的一部分，它為印度提供了關鍵的環境和安全監測系統。

"This satellite would have strengthened applications in agriculture, forestry, and even military surveillance. I congratulate all ISRO teams and partner industries," he added.

他補充說：“該衛星將加強在農業，林業甚至軍事監視中的應用。我祝賀所有ISRO團隊和合作夥伴行業。”

Despite the setback, many families and children who traveled from across the country to witness the launch were impressed by the event.

儘管遭受了挫折，但許多活動從全國各地旅行的許多家庭和兒童都印象深刻。

"We came all the way but couldn’t see the launch. Still, I feel proud just being here," said a child from Ranipet.

Ranipet的一個孩子說：“我們一路走來，但看不到發射。儘管如此，我就在這裡感到自豪。”

Another visitor, a student who aspires to join ISRO, expressed disappointment but also determination.

另一位願意加入ISRO的學生表示失望，但也決心。

"I came 150 kilometers hoping to see the launch. I’m disappointed today, but I’ll be back next time. I want to become the ISRO Chairman one day," he shared.

他分享道：“我來了150公里，希望看到發射。今天我很失望，但下次我會回來。我想有一天成為ISRO董事長。”

This incident marks a rare instance of failure for the PSLV, which has a nearly unblemished record. The anomaly will be part of the learning process for advanced space missions.

這一事件標誌著PSLV的罕見實例，該實例的記錄幾乎沒有任何記錄。異常將成為高級太空任務學習過程的一部分。
