SpaceX, owned by Elon Musk, is developing a Mars-based version of its Starlink internet service, aimed at facilitating faster communication between Earth and the Red Planet. This project was discussed at the November 7 meeting of the Mars Exploration Program Analysis Group (MEPAG), which supports NASA’s Martian missions. According to meeting notes, SpaceX’s proposal involves placing multiple satellites in Mars’ orbit to offer “full visibility and interoperability for the ground and orbital assets.”
Using advanced laser communication technology, Starlink will ensure continuous data transfer between Earth and Mars, even across the vast 1.5 astronomical unit gap (the distance between the two planets). The system is expected to achieve high-speed data transmission of 4 Mbps or more, which would support real-time image and data streaming from Mars, while also aiding future Mars missions and ground operations.
Musk confirmed the initiative on X (formerly Twitter), explaining that this is only the first step. “This is just a very basic first step. Earth and Mars will ultimately need >petabit/sec connectivity,” Musk wrote.

The concept of a Mars-based internet network has captivated many, drawing comparisons to science fiction. Some praised the ambitious idea, with one user saying, “Preparing internet access on Mars now before most people can even grasp the concept of traveling there is amazing. This is confidence in the future. I love this determination.” Another user added, “I have to admit this is pretty remarkable stuff.”
However, others raised concerns about potential issues, such as latency. One user noted, “The latency of a ping though…that would still lead to one heck of a lag. Even if you put the game servers in the middle, on the best day, you’re not going to do Diablo players from Mars and Earth in the same game.”
Starlink has already revolutionized internet access on Earth, offering high-speed connectivity anywhere, including in remote and disaster-stricken areas. The service operates through a network of satellites in Low Earth Orbit (LEO), eliminating the need for traditional cables. This proved essential during Hurricane Helene earlier this year when stranded individuals used Starlink to communicate.
