PSLV-C61成功取消了，但在第三阶段的异常导致任务失败。 ISRO承诺详细分析

Sriharikota | 2025年5月18日，印度第101卫星任务在地球观察卫星EOS-09未能实现其预期的轨道之后，周日遭受了重大挫折

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卫星任务在周日遭受了挫折，因为在Polar卫星发射车（PSLV-C61）上发射后，地球观察卫星EOS-09未能实现其预期的轨道。

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太空中心的发布开始按计划进行，ISRO确认在第二阶段的表现正常。但是，在第三阶段的关键问题导致异常，破坏了任务的成功。

“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上的一篇文章中说：“今天的PSLV-C61表现正常，直到第二阶段。由于在第三阶段进行了观察，因此无法完成任务。”

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

该机构补充说：“将进行技术审查来评估第三阶段的失败，并将相应地发布发现。”

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

这是PSLV的第63次飞行和27号XL配置，继续作为ISRO的Workhorse Launcher的遗产。

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配备了C波段合成孔径雷达（SAR），旨在在太阳同步极性轨道（SSPO）中运行，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.

科学家W Selvamurthy解释说，有效载荷是一个更广泛的星座的一部分，它为印度提供了关键的环境和安全监测系统。

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

他补充说：“该卫星将加强在农业，林业甚至军事监视中的应用。我祝贺所有ISRO团队和合作伙伴行业。”

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

尽管遭受了挫折，但许多活动从全国各地旅行的许多家庭和儿童都印象深刻。

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

Ranipet的一个孩子说：“我们一路走来，但看不到发射。尽管如此，我就在这里感到自豪。”

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

另一位愿意加入ISRO的学生表示失望，但也决心。

"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：“我来了150公里，希望看到发射。今天我很失望，但下次我会回来。我想有一天成为ISRO董事长。”

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.

这一事件标志着PSLV的罕见实例，该实例的记录几乎没有任何记录。异常将成为高级太空任务学习过程的一部分。
