Leading Astronomer Cautions that Elon Musk’s Mars Ambitions Could Be Perilous Misconceptions


SpaceX CEO Elon Musk’s goal to place a million people on Mars by 2050, including his ex-girlfriend Grimes, has been criticized by Martin Rees, a renowned astrophysicist and member of the Royal Households of the United Kingdom. Rees, who holds the title of “Astronomer Royal,” called Musk’s plans a “dangerous illusion” during his remarks for the House of Lords’ podcast Lord Speaker’s Corner.

Rees referred to Musk as an “extraordinary figure” with a “rather strange personality,” hinting at Musk’s increasingly unpredictable behavior. He also expressed skepticism about the feasibility of Musk’s Mars colonization plans. He stated, “I don’t think it’s realistic and we’ve got to solve those problems here on Earth…Dealing with climate change on Earth is a doddle compared to making Mars habitable. So I don’t think we should hold that out as a long-term aim at all.”

Rees further commented that while a few “crazy pioneers” might choose to live on Mars, the concept of mass migration to avoid Earth’s problems, as proposed by Musk and other space enthusiasts, is a dangerous illusion. He believes that it is far less hospitable than the South Pole.

Rees suggested that human exploration of space should be privately funded and not rely on public funds, like the ongoing collaboration between NASA and SpaceX. He argued that governments tend to be overly safety conscious, which can significantly increase costs. He proposed that the majority of space exploration should be performed by remote-controlled robots, with only those with a high risk tolerance venturing into space, funded privately rather than by taxpayers.

NASA is currently looking into commercial partners, including SpaceX, for Mars missions, which will undoubtedly require massive funding. Rees pointed out that long-term space travel poses significant health risks due to factors such as low gravity and cosmic radiation. He also urged for a focus on solving the problems caused on Earth before moving on to another planet.

Elon Musk has previously stated that his primary goal is to get humanity to Mars before his demise. However, the practicality and feasibility of such a mission continue to be debated among experts.
