NASA’s InSight hopes to detect “marsquakes”, deploys seismometer on Mars

Published

In another historic feat for NASA’s InSight lander, a seismometer has now been deployed on Mars, marking the first time a scientific instrument has been placed onto the surface of another planet. Once the craft’s team have things set up for readings, its instruments will begin measuring the internal vibrations of the red planet, hoping to ultimately learn about the activities and composition of its core and crust. InSight’s instruments will also study how powerful and frequent seismic activity is on Mars along with how often the surface is hit with meteorites. If we’re hoping to explore and possibly live there one day, this is all very important information to have.

After launching on May 5, 2018, aboard an Atlas rocket in California, InSight and its MarCO twin CubeSat companions traveled through deep space for around 6 months before landing on the Martian surface at 11:52 PST on November 26, 2018, an event watched live around the world, including a broadcast in Times Square, New York City. The planned mission for the craft is a little over 1 Martian year, i.e., about 2 Earth years, during which time it will aim to provide scientific data useful for understanding the processes that have shaped the rocky planets of our solar system. In other words, the things InSight learns about Mars will be directly relevant to our own planet as well.

InSight’s name is actually an acronym for “Interior Exploration using Seismic Investigations, Geodesy and Heat Transport”, each part being a reference to the specific science it will be conducting. There are several auxiliary instruments on board the lander that will assist or complement its main mission. However, there are 3 scientific instruments on the craft to help meet its objectives.

First, a seismometer named the Seismic Experiment for Interior Structure (SEIS) will study seismic waves from the Martian surface to study the planet’s crust. When magma moves or meteorites hit, the instrument will detect the motion and gather information that will tell scientists about Mars’ temperature, pressure, and composition. This is the instrument featured in the lander’s recent photo.

Second, a heat flow probe named the Heat Flow and Physical Properties Probe (HP3) will burrow more than 10 feet into the surface to measure the heat still flowing out of Mars, giving clues about how it evolved and whether Earth and Mars are made of the same materials. Finally, a radio science instrument named the Rotation and Interior Structure Experiment (RISE) will measure tiny changes in the location of InSight to measure Mars’ “wobbles” on its axis. This movement data will provide information about the planet’s core.

InSight is conducting its experiments on the western side of the Elysium Planitia of Mars, a smooth, flat region near the planet’s equator. The location was chosen from a pool of 22 candidate landing sites, all within Elysium, evaluated during several workshops from 2013-2015. The decision was made based on Elysium’s proximity to the equator (maximum sun for InSight’s solar arrays), low elevation (plenty of atmospheric space for its landing), lack of rocks and slopes (flat enough for the instruments to deploy and work properly), and the subsurface structure (so the digging instruments could burrow easily).

Next, InSight will finish setting up its remaining instruments and begin its full science mission. We can expect to continue receiving image updates from the lander as more milestones are reached. Here’s an extra bonus if you want to feel like you’re “there” with InSight: NASA’s “Experience InSight” interactive web page lets you control a virtual version of the lander in a Martian environment. You can deploy its solar panels, move around a few of its instruments, or just learn about the various parts that make up the mission. There are additionally two virtual cameras, just like the ones onboard the actual craft, enabling you to watch the movements you’re making, just like InSight’s team sees from their control center.

Elon Musk’s next Uranium in Uranus merch is Boring Company’s weirdest tease yet

Elon Musk teased a glowing new Boring Company merch idea, complete with a Geiger counter.

Elon Musk teased the next piece of Boring Company merchandise on X Saturday, and it is exactly as unserious as fans of the company’s product history have come to expect. “The next @boringcompany merch will put Uranium in Uranus,” Musk wrote in a thread posted early Saturday morning. He followed up by explaining that the item would glow in the dark, “because otherwise how could you find it,” and that a Geiger counter would be sold separately as “an optional strap-on.”

Musk closed the thread with a line that doubles as a mission statement for the tunneling company’s merchandise arm: “It’s not easy coming up with something that is both outrageously unsellable and yet extremely popular.”

The Boring Company has built a small but consistent side business out of novelty items that start as jokes and end up selling out. The company’s Not-a-Flamethrower raised roughly $10 million in a few days back in 2018, moving all 20,000 units it produced. Its Burnt Hair perfume, priced around $100 a bottle, sold out fast enough that scalpers were flipping units on eBay for ten times the retail price. Boring Bricks, made from tunneling spoil, followed the same playbook of teasing a product on X months before it became real.

Musk has not said what the actual item will be, only that it involves uranium and glows in the dark. Given the pattern, that vagueness is probably intentional. Past merch announcements have started as one-line jokes and taken weeks or months to turn into an actual product listing on the company’s site, and there is no guarantee this one follows through at all.

The timing lines up with a period of real momentum for the Boring Company outside of the joke merchandise. The company said last week it plans to double the number of operational stations on its Vegas Loop by the end of the year, a target tied to a hiring push for drivers and operations managers. Prufrock-5, one of the company’s tunnel boring machines, also just wrapped a test tunnel in Bastrop, Texas, and is expected to relaunch on its next assignment in November.

Whether the uranium joke turns into an actual product remains to be seen. Musk’s post did not include a price, a shipping date, or even a name for the item, which has historically meant a Boring Company website page goes up quietly, password protected, sometime before an announcement.

NASA taps SpaceX for more astronaut missions as Boeing Starliner remains grounded

NASA just gave SpaceX a $946 million contract for three more astronaut missions through 2030.

NASA has awarded SpaceX a $946 million contract modification covering three more astronaut missions to the International Space Station, according to an announcement the agency published Friday. The award adds Crew-15, Crew-16, and Crew-17 to SpaceX’s existing Commercial Crew Transportation Capability contract, bringing the agreement’s total value to $5.92 billion across 17 flights.

SpaceX confirmed the award on X, writing that it was excited for Falcon 9 and Dragon to launch NASA’s Crew-15, 16, and 17 missions to the Space Station from Florida. The new missions cover ground, launch, in orbit, and return operations, along with cargo transport and a lifeboat capability while docked at the station, and the period of performance runs through 2030.

The award follows a notice of intent NASA issued in May, when the agency first signaled it would purchase up to six additional post certification missions from SpaceX. Teslarati covered that filing at the time, noting NASA cited technical issues and schedule delays encountered by Boeing as a driving factor. Friday’s contract modification locks in three of those six missions, with the remaining three left open for NASA to award later, potentially to Boeing if Starliner clears certification.

Boeing’s CST-100 Starliner has still not flown an operational crew rotation mission for NASA. The spacecraft’s most recent crewed test flight in 2024 ended without the astronauts returning aboard Starliner, and the company has spent the time since working through thruster problems. SpaceX President Gwynne Shotwell said this week that SpaceX is not retiring Crew Dragon today, for sure, while stopping short of committing to fly it past 2030.

Crew-12 is currently docked at the space station, and NASA has said Crew-13 is targeting a launch in the coming weeks. The newly awarded Crew-15 through Crew-17 missions extend SpaceX’s role as NASA’s primary way of getting astronauts to and from orbit well into the back half of the decade, regardless of what happens with Starliner or Starship in the meantime.

New drone video shows Tesla’s Optimus Factory reaching a turning point

New drone footage shows Tesla’s dedicated Optimus factory steel frame nearing completion at Giga Texas.

Tesla’s dedicated Optimus factory at Gigafactory Texas is closing in on a finished steel frame, according to drone footage posted Thursday afternoon by longtime site observer Joe Tegtmeyer. In the video, Tegtmeyer said structural steel assembly is now about five column grids away from reaching the building’s north perimeter beam, putting the primary skeleton in its final stretch roughly six months after Tesla broke ground on the North Campus site in late March.

Tegtmeyer’s footage shows concrete already going in on three upper floors while crews continue laying rebar and pouring grade beam footings at ground level. That kind of parallel work, steel rising at one end of the site while concrete sets at the other, is a scheduling approach Tesla used at the original Giga Texas building and appears to be repeating here to save time before the plant’s targeted 2027 production start.

Teslarati has tracked the building’s progress since Tesla confirmed construction was officially underway in May, when the first steel structure went up on what was then bare, reclaimed land. The facility is part of a more than 5.2 million square foot expansion of Giga Texas’s North Campus that Tesla has said will eventually run nearly the length of the existing vehicle factory, over 4,000 feet, while sitting somewhat narrower. Musk has pegged the long term output target at 10 million Optimus units a year once the line is running at full capacity, a volume that would dwarf the one million unit pilot line Tesla is standing up separately at its Fremont, California factory.

Tesla Giga Texas to feature massive Optimus V4 production line

The Texas facility sits alongside another major buildout on the same campus. Terafab, the joint Tesla and SpaceX chip fabrication plant that will eventually supply the silicon running Optimus units in the field. Housing robot assembly and chip production on the same grounds is a deliberate supply chain decision, cutting down on the shipping and lead time that would otherwise sit between the two.

Tesla has not given an updated timeline beyond its previously stated goal of bringing high volume Optimus production online at the site in the summer of 2027. Fremont’s smaller pilot line began mass producing the current Gen 3 robot in January, with that plant expected to build tens of thousands of units this year primarily to generate the real world data Tesla needs to refine the robot’s software before Giga Texas ramps up. Six months of visible construction progress, tracked almost entirely through Tegtmeyer’s recurring drone flights, gives the clearest outside look yet at how seriously Tesla is treating that 2027 deadline.
