NASA’s InSight lander has spent the last year listening to the deep rumble of the red planet’s interior. And its first batch of data is in. The stationary lander found out that Mars’ magnetic field is constantly changing, but that’s not all. InSight also delivered the first direct evidence of marsquakes.

Here on Earth, geologists use seismometers to listen to the planet’s inner stirrings. InSight is the first robotic explorer to carry a seismometer to another planet. And it’s shown that Mars is not the dead, lifeless world it appears to be — the red planet is actually geologically active.

“This is the first mission focused on taking direct geophysical measurements of any planet besides Earth, and it’s given us our first real understanding of Mars’ interior structure and geological processes,” geologist Nicholas Schmerr of the University of Maryland said in a news release.

“These data are helping us understand how the planet works, its rate of seismicity, how active it is and where it’s active.”

InSight’s seismometer, an ultra-sensitive instrument provided by the French space agency, will shed some light on the red planet’s inner workings over the course of its mission. Officially dubbed the Seismic Experiment for Interior Structure, the SEIS instrument detected its first Martian rumblings last April.

Ever since, scientists were eager to get their hands on the full spectrum of data, to better understand just how active our celestial neighbor might be.

These first Martian murmurs were so faint, they’d probably go unnoticed by anyone on the surface. Roughly equivalent to about a 2 or 2.5 quake here on Earth, to InSight’s science team, these were incredibly exciting and just the beginning of a new era of Mars science.

Seismic waves can tell us a lot about a planetary body. They act like an ultrasound, allowing us to “peer” below the surface and determine the planet’s composition.

Here on Earth, seismic waves are caused by the movement of tectonic plates gliding over the planet’s mantle. When the plates jockey for position, stress builds up until it reaches a critical point, and that’s when an earthquake is triggered. But not every planetary body has these types of plates. The moon, for instance, has seismic activity that’s caused by a different method.

After a planetary body is formed, it has a primordial heat source that over time cools off. In the case of a rocky body, like the moon, that lacks any sort of tectonic plate movement, the seismic activity is caused by internal cooling. As the satellite cools, it ever so slightly shrinks, sending minute seismic waves propagating through its interior. The Apollo program recorded examples of this and InSight has now shown that Mars has similar activity.

Seismic data was collected over the course of 235 Martian days. 174 marsquakes were recorded during that time; 150 of those were shown to be similar to the Apollo program’s findings on the moon. Three of the other 24 produced wave patterns similar to quakes experienced here on Earth as a result of tectonic plate movement.

But as far as we know, Mars does not have tectonic plates. The science team was able to pinpoint the origin of three of the quakes: a fractured piece of land called Cerberus Fossae. Here the ground is cracked and fractured suggesting it was once tectonically or volcanically active. (Sometime within the last 10 million years, something pulled the ground apart here.)

Scientists are hoping that as more data comes in, they will be able to piece together what is causing Mars to tremble, and learn more about the red planet’s interior in the process.

SpaceX to become America’s Military data backbone for missiles, drones, and warfighters

The Space Force just handed SpaceX $2.29 billion to build the military’s space internet backbone.

The U.S. Space Force awarded SpaceX a $2.29 billion contract on May 26, 2026 to build the backbone of its Space Data Network, a satellite-based communications system designed to keep American military forces connected anywhere on Earth in real time. The contract is firm-fixed-price and requires SpaceX to deliver a fully operational prototype by the end of 2027.

In plain terms, the SDN Backbone is the plumbing behind the military’s space-based internet. It functions as a low Earth orbit satellite constellation providing robust, high-capacity, and low-latency data transport for the Joint Force, connecting sensors and weapons systems continuously, globally, and securely. Think of it as a private, hardened version of Starlink built specifically for battlefield communications, one that soldiers, ships, and aircraft can rely on even in contested environments where ground-based networks have been disrupted.

SpaceX is quietly becoming the U.S. Military’s only reliable rocket

The Space Force was direct about why SpaceX was selected. “The SDN Backbone leverages the best of commercial innovation and delivers a strong foundation for the SDN mission set — a huge benefit and enabler for our warfighters,” said USSF Col. Ryan Frazier.

“We aren’t trading speed for scale; we are demanding both. By using rapid prototyping and Other Transaction Authorities, we are ensuring our advanced solutions are integrated and delivered to the warfighter as fast as possible,” added USSF Lt. Col. Fry, SDN Backbone system program manager.

The SDN Backbone will work alongside the Space Development Agency’s Transport Layer, with the two systems forming a unified open architecture to provide critical data transport for current and future Department of War missions.

As Teslarati has reported, this is not SpaceX’s first Space Force contract of 2026. In April, the Space Force awarded SpaceX $178.5 million to launch missile tracking satellites, and SpaceX is already embedded in the Golden Dome missile defense software group. The $2.29 billion SDN Backbone award puts SpaceX at the center of how the American military communicates in space, a position with direct implications for its reported $1.75 trillion IPO valuation as the company heads toward a public offering as early as June 2026.

NASA’s first human outpost on the Moon starts now – SpaceX on deck

NASA named the rovers, landers, and vendors that will build America’s first Moon Base.

Published

NASA has laid out its most detailed Moon Base plan to date, describing a permanent outpost near the Moon’s south pole that the agency intends to build over the coming decade as a direct stepping stone to Mars. “The Moon Base will be America’s and humanity’s first outpost on another celestial world,” NASA Administrator Jared Isaacman said, adding that every mission crewed and uncrewed “will be a learning opportunity as we return to the lunar surface, build the infrastructure to stay, and master the skills required to live and operate in one of the most demanding and dangerous environments imaginable.”

The plan is structured in three phases involving both uncrewed and crewed missions to deliver equipment, vehicles, and infrastructure to the surface, with the first three moon base missions targeted to launch before the end of 2026.

Moon Base I, targeting fall 2026, will use Blue Origin’s Blue Moon Mark 1 lander to deliver scientific instruments to the Shackleton Connecting Ridge, the same region where Artemis astronauts will land. Moon Base II will send Astrobotic’s Griffin lander carrying more than 1,100 pounds of cargo including Astrolab’s FLIP rover to begin developing mobility systems on the surface. Moon Base III will carry the Lunar Vertex science mission on Intuitive Machines’ Nova-C Trinity lander to study lunar swirls near the south pole, with ESA and Korean science payloads aboard.

On the rover side, NASA awarded Astrolab $219 million and Lunar Outpost $220 million to build the first phase of Lunar Terrain Vehicles, with both rovers targeted for deployment to the lunar surface by 2028. Astrolab’s crewed rover weighs roughly 2,000 pounds and can reach over 6 mph. Lunar Outpost’s Pegasus rover can operate autonomously or via remote control at over 9 mph. Blue Origin separately received $188 million with an option worth $280.4 million to deliver cargo landers for rover transport.

NASA also confirmed that MoonFall, a mission deploying four survey drones to scout Artemis landing sites, has selected Firefly Aerospace to build the transport spacecraft, with a 2028 launch target.

SpaceX sits at the center of that commercial layer. SpaceX holds the NASA Human Landing System contract for the Starship-derived lander that will put astronauts on the surface under Artemis IV, currently targeting 2028. Before that can happen, SpaceX must demonstrate in-orbit propellant transfer at scale, a process requiring multiple Starship tanker launches to fuel a single mission. Water ice at the lunar south pole is central to the base’s long-term viability, as it can be converted into drinking water, breathable oxygen, and rocket fuel, directly reducing dependence on Earth resupply. That resource loop becomes far more practical if Starship can land and be refueled on or near the Moon itself.

Elon Musk has publicly stated that Starship V3, which recently completed its first flight, should be capable enough for initial Mars missions. The Moon Base plan announced Tuesday is the infrastructure layer that connects everything between those two ambitions, and SpaceX is the only American company currently contracted to build the rocket that gets humans to either destination.

SpaceX’s Starlink product has just gotten its latest airline adoptee, and the move marks the successful partnership of three of the “Big Four” U.S. airlines.

American Airlines announced on Tuesday that it would utilize Starlink in more than 500 narrowbody aircraft beginning in the first quarter of 2027. These include the Airbus aircraft in its fleet, including the new A321XLR and A321neo.

With the new partnership with American Airlines, Starlink is now present on three of the largest airlines in the country: American, United, and Southwest.

Starlink has been on a tear over the past year, as it has continued to be adopted by a wide variety of airlines as a more consistent and reliable way to provide WiFi to its passengers. It has already gained a great reputation among residential users, but its biggest commercial application appears to be how it is being used in the air.

The only airline of the Big Four not to adopt Starlink thus far is Delta, which chose to opt for the alternative, which is Amazon Leo. CEO Ed Bastian said to Bloomberg that Delta chose Amazon’s product over Starlink’s because “the opportunities, in terms of the improved bandwidth with a much lower price point than what we’ve ever seen from Starlink, will make a big difference.”

Delta will not start installing Amazon Leo until 2028.

“Of course, we expect Starlink will be warning people that we’re going to go with an inferior product,” Bastian said. “But I’m not too worried about partnering with Amazon.”
