While SpaceX founder Elon Musk has pledged to despatch a crew of Optimus robots aboard the first titanic Starships to be launched to Mars, their interplanetary odyssey is likely to be short-lived, says a leading robotics scholar.
The world’s richest techno-aristocrat told his 200 million followers on the messaging platform X that the Tesla-conceived droid could be lofted as soon as 2026: “Slight chance of Starship flight to Mars crewed by Optimus in Nov/Dec next year. A lot needs to go right for that.”
“More likely,” he added, “first flight without humans in ~3.5 years, next flight ~5.5 years with humans.”
Yet unless Tesla’s leadership pulls off a series of sensational technological advances in improving the robustness of the cloned Optimus bots before they blast off for Mars, they are likely to enter the same downward spiral that is a hallmark of all humanoid robots, across the planet, at this early stage in their evolution, says Christian Hubicki, an acclaimed scholar who heads the Optimal Robotics Laboratory at Florida State University.
While researchers are racing to strengthen and perfect these replicated humans, Professor Hubicki tells me, humanoid robots worldwide still collectively share an array of Achilles heels.
“Humanoids fall down. They break. Their code crashes.”
“The robotics field has made enormous strides with humanoids, widening their skillsets and driving down costs, but reliability remains a major hurdle,” adds Hubicki, who conducted his postdoctoral research in engineering and robotics at the Georgia Institute of Technology, one of the top American science universities.
“Right now, humanoids aren’t reliable enough to be autonomous on Earth, let alone Mars.”
With the planned launch of the Optimus squad of identical robots, SpaceX’s chief designer would be following the lead of NASA, which sent its cutting-edge Robonaut 2, a space android created in the image of astronauts, to the International Space Station more than a dozen years ago.
The Robonaut was packed with next-generation processors and cameras, a LIDAR scanner and an AI-powered image recognition system to navigate its surroundings.

R2 was trained to interact with oxygen-breathing spacefarers on the ISS and with ground-control scientists on the spinning Earth below.
“Humanoid robots are not entirely new to space, but only on space stations where humans are already there to fix them,” Professor Hubicki tells me across a series of interviews.
“Mars is a different ballgame.”
When NASA launched Robonaut 2 to the International Space Station in 2011, after more than a decade of developing this first robot-aeronaut, “it was built to assist human astronauts who were already on the space station, a first step toward freeing their precious attention for other work.”
“It was a test platform that performed a some proof-of-concept tests with constant supervision from the ground,” he says.
While Robonaut 2 underwent a series of demos with simple autonomous tasks, mostly it was teleoperated by mission controllers, becoming their celestial avatar while speeding through orbit at 28,000 kilometers per hour.

With Robonaut’s vulnerabilities, Hubicki says, “critically on the ISS, humans are there to help and fix the robot when it inevitably falters.”
“On Mars, there are no humans to rescue it, and replacement parts are a nightmare to ship in.”
The globe-spanning quest to develop androids that approach humans in intelligence and have a high degree of reliability is now speeding up.
“In space, reliability is king,” Hubicki says.
“On Mars, it is life or death.”
“Without a major technological leap in humanoid reliability,” he predicts, “an unaccompanied humanoid on Mars wouldn’t be functional for long.”
Although the Robonaut tested out on the International Space Station is now ensconced at the Smithsonian’s National Air and Space Museum, researchers at NASA say they aim to develop a next-generation droid that can accompany astronauts on high-risk spacewalks outside the ISS, all as part of a lead-up to Mars missions of the future.

Astronauts aboard a Mars orbiter could one day teleoperate a squadron of robots – avatars deployed to map out potential landing sites along the Martian dunes and beam back their 3D imagery, say researchers at the NASA Ames Research Center and at the Jet Propulsion Lab attached to CalTech.
As an alliance of robotic and human explorers for future Mars missions unfolds, Professor Hubicki says, “There are interesting research approaches toward sending unaccompanied robots to Mars to build a [human] habitat, but those solutions are very much in the concept stage.”
Future-generation robots patterned after humans, those that have become at least as strong as their creators, “have the potential to excel in dangerous environments.”
“You can see that theoretical use case on another planet,” he says.
“Could humanoids be used to go where it’s too dangerous for humans to go?”
“Absolutely, in theory. That’s my aspiration and that of many researchers in the field.”
Professor Hubicki says his own research on crafting precise robotic doppelgängers of humans is partly aimed at creating Men of Steel first responders who could speed into a burning skyscraper and begin rescuing those trapped inside—a superhero role that could be transplanted to Mars.
He suggests, meanwhile, that Elon Musk should consider testing out his Optimus aeronauts on a closer designation before launching them to the Red Planet, which is up to 400 million kilometers distant from Earth.
“If I were in charge of a space humanoids program, I would recommend test deployments with future lunar missions before we shoot them off to Mars.”
“Yes, the moon provides its own unique challenges — moon dust is a nightmarish tangle of sharp and jagged particles that wear down equipment quickly.”
“But the moon is closer than Mars, making it easier to staff with technically skilled humans and replacement parts would be far easier to ship.”
SpaceX has already signed dual agreements, valued at $4 billion-plus, with NASA to shuttle astronauts from lunar orbit down to the Moon’s South Pole starting in 2027.
SpaceX’s lunar lander, the massive Starship super-capsule, is designed to transport 100 spacefarers, and could speed a brigade of Optimus droids to a lunar touchdown alongside their NASA allies.
