Following the successful completion of a test that saw part of SpaceX's Starship return to its launch pad, the company's goal of creating a fully reusable and quickly deployable rocket has taken a major leap forward. BBC's science correspondent, Pallab Ghosh, delves into the technical challenges of this feat and addresses concerns about the environmental impact of such a rocket. This development comes after a public dispute between Elon Musk and the Federal Aviation Administration over permits and environmental concerns.
SpaceX's Starship: A Leap Towards Reusable Rockets
SpaceX, the aerospace company founded by Elon Musk, has made significant progress towards its goal of developing a fully reusable and rapidly deployable rocket system. This milestone was achieved recently with the successful return of part of the Starship to its launch pad, following a test flight.
Background
SpaceX's Starship is a massive reusable spacecraft designed to carry both crew and cargo into space. It consists of a first stage called the Super Heavy booster and a second stage called the Starship itself. The Super Heavy is responsible for lifting the Starship into orbit, while the Starship serves as the primary vehicle for travel beyond Earth's atmosphere.
The development of Starship is crucial for SpaceX's plans to establish a permanent human presence on Mars and enable interplanetary travel. By creating a fully reusable rocket, SpaceX aims to drastically reduce the cost of space travel and make it more accessible.
Technical Challenges
Developing a fully reusable rocket system is no easy task and presents numerous technical challenges. One of the primary obstacles is the ability to withstand the extreme heat and pressures encountered during re-entry into Earth's atmosphere. SpaceX has overcome this hurdle through a combination of advanced heat shielding and precise control during descent.
Another challenge lies in the separation and recovery of the Super Heavy booster and Starship. To achieve rapid reusability, both stages must be able to return safely to the launch pad for refurbishment. SpaceX has employed a range of innovative techniques, including onboard guidance systems and precise landing maneuvers, to enable this separation and recovery process.
Environmental Concerns
The development and operation of Starship have raised concerns about its potential environmental impact. Critics have expressed worry that the rocket's methane-based fuel could contribute to greenhouse gas emissions. SpaceX has addressed these concerns by emphasizing the efficiency of their propulsion system and their plans to transition to renewable energy sources in the future.
Dispute with Federal Aviation Administration
In February 2022, SpaceX and the Federal Aviation Administration (FAA) engaged in a public dispute over permits and environmental concerns related to the Starship launch site in Boca Chica, Texas. The FAA raised concerns about the project's potential impact on local wildlife and the environment. After extensive discussions and negotiations, SpaceX eventually received approval for the launch site in June 2022.

A viral video claiming to show American astronaut Sunita Williams returning safely to Earth after a 127-day space tour is making rounds on social media and X. However, a closer look reveals that the video is from 2012 and shows Williams giving a tour of the International Space Station. Williams is actually still in space and is expected to return to Earth in February 2025. Further investigation reveals that the watermark on the video belongs to "UNILAD Adventure."
A recent DNA study has revealed that Christopher Columbus, the 15th century explorer, was actually a Sephardic Jew from western Europe. After 21 years of investigation, researchers concluded that Columbus's DNA was "compatible" with his being of Jewish origin. This finding sheds new light on the origins of the controversial figure, who was previously believed to be Italian. The study also confirms that the remains at Seville Cathedral belong to Columbus, solidifying his final resting place after centuries of debate.
In a historic feat, SpaceX successfully caught its Falcon Heavy booster mid-air using giant mechanical arms after its test flight in Texas. This accomplishment, spearheaded by CEO Elon Musk, marks a crucial step in the company's goal of reusing rockets and cutting costs. With future Starship launches planned for the Space Coast, this revolutionary booster recovery will play a key role in ensuring public safety and advancing the space industry towards the future.
Anustup Mukhopadhyay, a post-graduate trainee, is one of six junior doctors fasting in protest of the rape and murder of a junior doctor from R.G Kar Medical College and Hospital. However, due to serious deterioration in his medical condition, he was rushed to Calcutta Medical College and Hospital. His condition has worsened due to continuous fasting, with symptoms of stomach cramps and blood in his stool. Despite insisting on staying in the protest, he was admitted to the hospital for treatment. In solidarity, doctors from private hospitals in West Bengal have announced a partial cease-work for 48 hours in support of the junior doctors' movement.
