Another blow for Elon Musk as his $150 billion ticket to Mars crashes

Elon Musk's Starlink internet is down for users worldwide.

Downdetector, a site that monitors online outages, shows issues hit the SpaceX internet around 1:30pm ET.

Users cited sluggish connections, intermittent service and in many cases, total blackout

Musk has previously stated that Starlink's profits are 'being used to pay for humanity getting to Mars.'

While it's unclear how much revenue the company generates daily, a widespread service disruption could pose a setback to those lofty interplanetary ambitions.

Some analysts project that Starlink could be valued at around $150 billion, considering factors such as projected revenues and market conditions, but the company has not made an official announcement. 

Downdetector shows disruptions across the US, impacting users in Dallas, San Francisco, Phoenix, Chicago, Atlanta, Minneapolis and Washington DC.

Parts of South America, the UK and Australia are also experiencing issues.

The outage has left many customers frustrated, with many posting on Musk's X how this is the second outage in just the past few weeks.

'Starlink down, apparently, widespread. Website unresponsive. July 25, unexpected outage, never really explained. Again, today, Aug 18. What's up?' one user shared on X.

Another Starlink customer posted: 'Looks like @Starlink is down again. We’ve had more outages in the last month than in the last 5 years combined.'

Starlink's Residential plan costs $120 per month, while the Residential Lite plan costs $80 per month.

There are also Roam plans for users who need internet on the go, with prices ranging from $50 to $165 per month. And the standard Starlink kit costs $349 plus shipping.

In May, Musk unveiled bold new plans for SpaceX's strategy to colonize Mars, detailing what he called the next phase in space exploration. 

While much of the presentation focused on landing a Tesla Optimus robot in 2026, the billionaire announced that SpaceX will also send Starlink satellites to provide internet to those who choose to live on the Martian world.

'Ideally, we'll be able to take anyone who wants to go to Mars,' he said. 'And bring all the equipment needed to make it self-sustaining, to let it grow on its own.'

The goal, he emphasized, is to ship enough resources to the Red Planet so that if supply missions from Earth suddenly stop, life on Mars can continue uninterrupted.

'Having two strong, self-sustaining planets will be critical for the long-term survival of civilization,' Musk added.

He believes a multiplanetary existence could extend humanity's lifespan tenfold.

SwRI study supports theory that asteroids Bennu and Ryugu are part of the Polana family

SAN ANTONIO — August 18, 2025 — A Southwest Research Institute (SwRI) review of data collected from near-Earth asteroids Bennu and Ryugu supports the hypothesis that they were originally part of the Polana collisional family in the main asteroid belt between the orbits of Mars and Jupiter.

The study compared spectroscopy data from Polana with spacecraft and laboratory data from Bennu and Ryugu samples, discovering similarities in their near-infrared spectrum sufficient to support the theory that they originate from the same parent asteroid.

“Very early in the formation of the solar system, we believe large asteroids collided and broke into pieces to form an ‘asteroid family’ with Polana as the largest remaining body,” said SwRI’s Dr. Anicia Arredondo, lead author of the study. “Theories suggest that remnants of that collision not only created Polana, but also Bennu and Ryugu as well. To test that theory, we started looking at spectra of all three bodies and comparing them to one another.”

Arredondo and her team applied for time on the James Webb Space Telescope to observe Polana using two different spectral instruments focusing on the near-infrared and mid-infrared wavelengths. She then compared that data with the spectral data from physical samples of Ryugu and Bennu collected by two different space missions. The Japan Aerospace Exploration Agency’s Hayabusa2 spacecraft rendezvoused with Ryugu in 2018 and collected samples returned to Earth in late 2020. NASA’s OSIRIS-REx spacecraft encountered Bennu in 2020 and collected samples returned to Earth in late 2023.

Bennu and Ryugu are considered near-Earth asteroids because they orbit the Sun within the orbit of Mars; however, they are not considered a danger to Earth, having a closest approach of about 1.9 and 1 million miles, respectively. Both Bennu and Ryugu are relatively small compared to Polana. Bennu is about one third of a mile in diameter, or about the size of the Empire State Building. Ryugu is twice as large, but Polana dwarfs them both, measuring roughly 33 miles wide. Scientists believe Jupiter’s gravity pushed Bennu and Ryugu out of their orbit close to Polana.

“They are similar enough that we feel confident that all three asteroids could have come from the same parent body,” Arredondo said.

The team noted that the spectral data from the asteroids had variances and differences, but not enough to disprove the hypothesis that they all share a common origin.

“Polana, Bennu and Ryugu have all had their own journeys through our solar system since the impact that may have formed them,” said SwRI’s Dr. Tracy Becker, a co-author of the paper. “Bennu and Ryugu are now much closer to the Sun than Polana, so their surfaces may be more affected by solar radiation and solar particles.

“Likewise, Polana is possibly older than Bennu and Ryugu and thus would have been exposed to micrometeoroid impacts for a longer period,” Becker added. “That could also change aspects of its surface, including its composition.”

The “JWST spectroscopy of (142) Polana: Connection to NEAs (101955) Bennu and (162173) Ryugu” paper will be published in the Planetary Science Journal and will be accessible at DOI: 10.3847/PSJ/ade395.
