IThis was one of the most impressive technology events of the year. On October 13, Starship, the world’s largest and most powerful rocket, blasted into space from a launch pad in Texas. The main booster reached an altitude of more than 65 km and then began returning to Earth at speeds exceeding the speed of sound.
A crash was averted when the rocket, developed by Elon Musk’s SpaceX company, reignited its engines, slowed, and came to a grinding halt above the tower from which it had launched just seven minutes earlier. The scissor’s claws grabbed the massive launcher, gripping it tightly, ready to refurbish and fire again.
“Today is textbook day in engineering history,” said SpaceX engineer Kate Tice.
prestigious research journal science “This feat heralds a new era of affordable heavy-lift rockets that can reduce the cost of doing science in space,” the company said last month in awarding Starship’s October flight. Announced. This year’s breakthroughs.
Musk’s company has already cut the cost of putting cargo into Earth orbit by one-tenth, the magazine said. Further reductions of similar magnitude can be expected when Starship, the most powerful launcher ever built and designed to be completely and rapidly reusable, becomes fully operational later this year, it added.
This view is shared by many space engineers, who believe Starship is poised to take a major leap forward with a schedule of launches every two to three weeks. SpaceX engineers have learned how to salvage and reuse the main booster stage and plan to do the same with the upper stage this year.
With a total of 25 flights planned over the next year, this is an incredibly ambitious program. “You don’t have to be a rocket scientist to understand that their research schedule is unprecedented,” astrophysicist Ehud Behar, a Technion professor at the Israel Institute of Technology, told the website Space.com.
For scientists, the benefits of Starship are clear. The cost of missions on reusable launch vehicles could drop significantly from current levels, making it possible to conduct research in space that was previously unaffordable. This point is important, he said. science In an editorial about Starship’s achievements, he said:
Until now, access to space was too precious to risk failure, the magazine said, and NASA missions tested components over and over again, driving up costs. “But regular Starship flights will give scientists more opportunities, allowing them to build instruments using inexpensive off-the-shelf parts and launch them more frequently.”
In addition to single vehicles, fleets of robotic probes could be sent to Mars, and fleets of mirror segments could be flown in formation to create giant self-assembling telescopes in space. While such a vision is exciting, there are downsides to Musk’s rocket success.
First, Starship could destroy NASA’s own rocket system, the troubled and extremely expensive Space Launch System (SLS), which the agency has been planning for decades. Unlike the reusable Starship, its rocket is expendable, while launching SLS will cost billions of dollars compared to the $10 million goal Musk has planned for the system. It is expected that it will cost. Many scientists predict that Starship will eliminate the need for SLS within a few years.
Another major problem for many scientists involved with SpaceX is that they have difficulty accepting Musk’s right-wing politics and close ties to Donald Trump. He is a vocal critic of U.S. immigration policy, has disdain for many Democratic politicians, and was recently given permission by President Trump to cut $500 billion from the U.S. federal budget.
In any case, Musk’s hopes for Starship have less to do with scientific aspirations and much more to do with his desire to eventually begin colonizing Mars using giant rockets. Last September, he promised that SpaceX would launch its first unmanned Starship mission to Mars in two years. If successful, manned flights would follow within four years. Ultimately, Musk said he envisions a potential colony of up to 1 million people on Mars within 30 years.
The controversial billionaire’s plans brought him a lot of attention and ridicule. Indeed, we have sent humans on a 140-meter-mile journey to the Red Planet, survived blasts of dangerous cosmic radiation, and figured out how to grow food in an atmosphere where water is scarce and the average pressure is less than 1% that of Earth’s oceans. Finding the level – challenging to say the least.
Leaving Earth for Mars is “like leaving a cluttered room to live in a toxic waste dump,” Kelly and Zach Weinersmith write in their book. Cities on Mars: Can and should we settle in space? And have we really thought about this?, which one Winner of the 2024 Royal Society Trivedi Scientific Book Award.
This is a view echoed by Astronomer Royal’s Martin Rees, who has also attacked Musk’s Mars proposal. “We should never expect mass immigration from Earth,” he says. “It’s a dangerous delusion to think that space can escape Earth’s problems. We have to solve them here. Dealing with climate change may seem daunting, but Mars Nowhere in our solar system are environments as harsh as Antarctica, the ocean floor, or the top of Mount Everest.
“For ordinary risk-averse people, ‘Planet B’ does not exist.”
From this perspective, Starships may have some impact on space science, but they are unlikely to change the course of human history.
