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.

WHO has released its first-ever global guideline on managing sickle cell disease (SCD) during pregnancy, highlighting the dangers faced by women and their babies. SCD is an inherited blood disorder with potentially fatal consequences, and the health risks intensify during pregnancy. The new guideline aims to improve outcomes for pregnant women with SCD and calls for more investment in evidence-based treatments and disease awareness. With SCD on the rise globally, increasing numbers of maternity care providers need to be equipped to handle its challenges.
On Thursday, March 19 at 5:01 a.m. ET, the vernal equinox or the first day of spring will take place in the Northern Hemisphere. This marks the beginning of the season of longer days and warmer weather as the sun's rays fall directly on the equator. Despite popular belief, day and night are not exactly the same length on the equinox due to atmospheric refraction. The summer and winter solstices and the autumnal equinox also have significant impacts on the Earth's tilt and the length of daylight hours.
A new, inexpensive Arduino-based logger has been developed for accurately mapping the depths of water bodies. By using budget-friendly hardware such as a GPS module and an SD card, combined with a standard NMEA capable echolot sounder, this device is accessible and practical for scientists, recreational enthusiasts, and more. With the added use of Python and matplotlib, users can now easily transform the collected data into detailed depth maps, revealing vital information about water levels and shallow spots in various environments.
After a 28-hour journey through space, Group Captain Shukla has become the first Indian to board the International Space Station (ISS). Accompanied by three other astronauts from the Axiom-4 mission, the ISS is now hosting a total of 11 people. Shukla was welcomed with hugs by the astronauts already stationed at the ISS and presented with the astronaut number 634. As the pilot of the mission, Shukla was given a number ahead of his fellow rookie astronauts and was offered a liquid diet to refresh himself before exploring the six-bedroom facility in space.
Indian astronaut Shubhanshu Shukla has successfully docked with the International Space Station on the Axiom Mission 4. This marks a proud milestone in Indian space history, as Shukla becomes the first Indian to reach the ISS. The docking process involved intricate procedures, and upon arrival, Shukla and his crew were welcomed with warm hugs and will conduct various experiments during their 14-day mission on the ISS.
After a 28-hour journey, Indian astronaut Shubhanshu Shukla and three other astronauts were welcomed onto the International Space Station (ISS) by the expedition team. Shukla expressed his gratitude and excitement for the 14-day mission, where they will conduct scientific experiments and interact with people on Earth. He also shared his amazement at the view and the warm welcome he received from the ISS crew.
Indian astronaut Shubhanshu Shukla has been launched to the International Space Station as part of the Axiom 4 mission aboard the SpaceX Dragon spacecraft. The spacecraft is currently en route to the ISS and is expected to dock with the Harmony module on June 26. The mission, led by Peggy Whitson, will last for two weeks and include scientific research, outreach activities, and commercial projects. Shubhanshu Shukla is joined by mission specialists from ESA and HUNOR. Get to know all about this historic mission carrying an Indian astronaut to space after 40 years.
After multiple delays, the Axiom-4 mission has finally launched with Indian astronaut Shubhanshu Shukla onboard for an important space mission. The spacecraft, carrying Shukla as the pilot along with three other astronauts, will dock at the International Space Station in a few hours. This joint mission between India, Poland, and Hungary marks a significant step in international human spaceflight collaborations and showcases India's ambitions in global space exploration. Shukla's journey not only symbolizes India's return to human spaceflight but also propels the country's human space program to new heights.
