ISRO chief S. Somanath explains why India missed the chance to lead Sunita Williams’ rescue operation | – Times of India

Must read

NASA has selected Elon Musk’s SpaceX to return astronauts Sunita Williams and Barry Wilmore to Earth early next year, following an unexpected extension of their stay aboard the International Space Station (ISS). This article delves into the details of this decision, the reasons behind it, and the current limitations of the Indian Space Research Organisation (ISRO) in space rescue missions.

Sunita Williams extended stay in space and upcoming return

Sunita Williams and Barry Wilmore originally travelled to the ISS on Boeing’s Starliner with a mission planned for eight days. However, technical issues with the Boeing spacecraft have caused their stay to extend significantly. What was meant to be a brief visit has now turned into over 78 days in orbit. NASA has scheduled their return for February next year, utilising SpaceX’s Crew Dragon spacecraft. This mission will be integrated into the routine astronaut rotation, with the Crew Dragon scheduled to launch next month.

ISRO’s current limitations

In a recent podcast, ISRO Chairman S. Somanath addressed the question of whether India could have led the rescue mission for Williams and Wilmore. He acknowledged that ISRO currently lacks the capability to undertake such a mission. According to Somanath, “Right now, we can’t do anything. We don’t have a spacecraft that can go there and save her. It is not possible.” He explained that only the U.S. and Russia possess the spacecraft necessary for conducting such rescue operations.

Technical difficulties with Boeing’s Starliner

The Boeing Starliner has faced significant technical challenges, leading to multiple delays and anomalies. Despite ongoing tests and efforts to address these issues, the spacecraft is not yet deemed reliable enough for a safe return of astronauts. Somanath noted, “The Boeing Starliner showed some anomaly, but they don’t want to take a risk. The launch was postponed many times, and they took a chance and launched it. But they don’t want to take the risk in returning her.”

NASA’s choice: SpaceX’s Crew Dragon

NASA’s decision to use SpaceX’s Crew Dragon for the return mission underscores the importance of reliability in human spaceflight. SpaceX has demonstrated a proven track record with its Crew Dragon spacecraft, which has been successfully used for several missions. This choice reflects the critical need for dependable technology in ensuring astronaut safety during unforeseen circumstances.

Technological and logistical challenges

The situation highlights the technological and logistical challenges faced by space agencies in managing human space missions. Ensuring astronaut safety, especially during unexpected scenarios, is complex and requires precise execution and thorough planning. The difficulties encountered with the Starliner serve as a reminder of the intricacies involved in human spaceflight.

ISRO’s future aspirations

ISRO continues to focus on various space exploration projects, including the Gaganyaan mission, which aims to send Indian astronauts into space. While ISRO has made significant strides in space technology, it acknowledges that it still has some way to go before being capable of undertaking complex rescue missions like the one that SpaceX is about to perform.
