NASA has deployed a small dome on Mars to protect its “marsquake” detector

Published

on

Before NASA’s InSight lander gathers data on Martian surface vibrations, aka “marsquakes”, it needs to protect its seismographic instrument from the winds and temperature changes during its stay on the red planet. Since wild temperature swings on Mars can mean fluctuations of about 170 degrees Farenheit over the course of a Martian day (sol), contractions and expansions of the seismometer were a problem needing to be addressed. To do that, an instrument shield was designed which has now been deployed as a first line of defense: It’s a white dome with a chain mail and thermal blanket skirt on the bottom called the “Wind and Thermal Shield”. After a successful dome deployment on Saturday, another milestone for the craft has been reached, bringing InSight’s team one step closer to understanding the secrets of the planet’s early formative years by studying its core.

InSight (short for “Interior Exploration using Seismic Investigations, Geodesy and Heat Transport”) was launched aboard an Atlas rocket in California on May 5, 2018, arriving at its destination on November 26, 2018. After a perfect live-streamed Martian surface landing shortly thereafter, Earthlings were treated to a (slightly dusty) photo taken by one of InSight’s on-board cameras, providing visual confirmation of the arrival. In the following days and weeks, ‘selfies’ along with other goodies were sent, such as the sound of Martian wind, as the craft meticulously placed its seismometer on the ground and continued its preparation for its full science mission of studying the heart of Mars as well as its atmosphere and weather patterns.

In addition to a protective dome, InSight’s seismometer itself adjusts for the changing Martian surface. As some parts expand and contract, other parts do the reverse to balance out the effect. Inside the dome, the seismometer is also contained in a titanium, vacuum-sealed container, the combination of which helps insulate the instrument even further from environmental hazards. The high-carbon dioxide content of Mars’s atmosphere is slow to conduct heat under the planet’s low pressure environment, further protecting InSight’s mission from local damaging effects.

Two tiny history-making satellites, collectively named MarCo, joined InSight on its journey to Mars. These briefcase-sized CubeSats’ initial job of demonstrating their relay capabilities during the craft’s landing event successfully sent data back to scientists on Earth much quicker than they would have received without them (near real-time, actually). Due to transmission delays and the locations of other satellites already orbiting the planet, InSight’s short journey to the surface may have taken hours for scientists on Earth to confirm otherwise. One of the MarCo satellites even sent back a photo of Mars as it flew by the planet, the low-cost mission itself representing a hopeful outlook on the future of deep space exploration. NASA has not made contact with the two tiny travellers since January 4, 2019, however, and both craft are now located over a million miles past Mars in Sun-centric orbits.

Now that InSight’s seismometer is on the surface and protected, it will proceed to deploy its heat flow probe next week. Essentially, this means the craft will drill almost 16 feet into the Martian surface and measure the heat of the planet’s interior. The goal of this research is to determine whether Mars is made of the same stuff as the Earth and the Moon, potentially answering questions about all of the planetary bodies’ evolution. Stay tuned!

The United Auto Workers (UAW) has publicly expressed solidarity with Swedish union IF Metall as its strike against Tesla continues, adding international attention to the extended labor dispute in the European country. 

UAW supports IF Metall’s strike

In a post shared on social media, the United Auto Workers stated that it stands with IF Metall workers who are striking against Tesla Sweden. UAW Region 8 Director Tim Smith stated that the union fully supports IF Metall’s efforts to secure a collective bargaining agreement with the automaker.

“UAW stands with IF Metall workers on strike against Tesla, fighting for a collective bargaining agreement. UAW Region 8 Director Tim Smith pledged the UAW’s full support and solidarity,” the UAW International Union stated in its post

IF Metall launched its strike against Tesla Sweden in late 2023 over the electric car maker’s refusal to sign a collective agreement. The action has since been supported by other unions through sympathy strikes affecting ports, logistics, and service operations.

Tesla Sweden has maintained that it complies with Swedish labor laws and offers competitive pay and benefits, though the company has not publicly commented on the UAW’s latest show of support.

Tesla owners get union attention

Pro-union groups in Sweden have recently expanded their outreach beyond Tesla’s facilities and workforce. Activists have begun distributing informational leaflets against the EV maker directly on Tesla vehicles parked across Stockholm, as per a report from Swedish outlet Dagens Arbete.

The yellow slips, designed to resemble parking notices, urge regular Tesla owners to pressure the company into signing a collective agreement. Organizers involved in the effort have argued that the leaflets are intended to simply inform consumers rather than single out individual owners. When owners are present, however, activists stated that they explain the dispute verbally.

Tesla has not issued a public response regarding the leaflet distribution campaign as of writing.

SpaceX used the Super Bowl broadcast to promote Starlink, pitching the service as fast, affordable broadband available across much of the world.

The advertisement highlighted Starlink’s global coverage and emphasized simplified customer onboarding, stating that users can sign up for service in minutes through the company’s website or by phone in the United States.

The campaign comes as SpaceX accelerates Starlink’s commercial expansion. The satellite internet service grew its global user base in 2025 to over 9 million subscribers and entered several dozen additional markets, as per company statements.

Starlink growth and momentum

Starlink has seen notable success in numerous regions across the globe. Brazil, in particular, has become one of Starlink’s largest growth regions, recently surpassing one million users, as per Ookla data. The company has also expanded beyond residential broadband into aviation connectivity and its emerging direct-to-cellular service.

Starlink has recently offered aggressive promotions in select regions, including discounted or free hardware, waived installation fees, and reduced monthly pricing. Some regions even include free Starlink Mini for select subscribers. In parallel, SpaceX has introduced AI-driven tools to streamline customer sign-ups and service selection.

The Super Bowl appearance hints at a notable shift for Starlink, which previously relied largely on organic growth and enterprise contracts. The ad suggests SpaceX is positioning Starlink as a mainstream alternative to traditional broadband providers.

Tesla engineers deflected calls from this tech giant’s now-defunct EV project

Tesla engineers deflected calls from Apple on a daily basis while the tech giant was developing its now-defunct electric vehicle program, which was known as “Project Titan.”

Back in 2022 and 2023, Apple was developing an EV in a top-secret internal fashion, hoping to launch it by 2028 with a fully autonomous driving suite.

However, Apple bailed on the project in early 2024, as Project Titan abandoned the project in an email to over 2,000 employees. The company had backtracked its expectations for the vehicle on several occasions, initially hoping to launch it with no human driving controls and only with an autonomous driving suite.

Apple canceling its EV has drawn a wide array of reactions across tech

It then planned for a 2028 launch with “limited autonomous driving.” But it seemed to be a bit of a concession at that point; Apple was not prepared to take on industry giants like Tesla.

Wedbush’s Dan Ives noted in a communication to investors that, “The writing was on the wall for Apple with a much different EV landscape forming that would have made this an uphill battle. Most of these Project Titan engineers are now all focused on AI at Apple, which is the right move.”

Apple did all it could to develop a competitive EV that would attract car buyers, including attempting to poach top talent from Tesla.

In a new podcast interview with Tesla CEO Elon Musk, it was revealed that Apple had been calling Tesla engineers nonstop during its development of the now-defunct project. Musk said the engineers “just unplugged their phones.”

Musk said in full:

“They were carpet bombing Tesla with recruiting calls. Engineers just unplugged their phones. Their opening offer without any interview would be double the compensation at Tesla.”

Interestingly, Apple had acquired some ex-Tesla employees for its project, like Senior Director of Engineering Dr. Michael Schwekutsch, who eventually left for Archer Aviation.

Tesla took no legal action against Apple for attempting to poach its employees, as it has with other companies. It came after EV rival Rivian in mid-2020, after stating an “alarming pattern” of poaching employees was noticed.
