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!

Tesla has applied to conduct local Full Self-Driving (Supervised) testing in the city of Jönköping, Sweden.

As per local outlet Jönköpings-Posten, Tesla has contacted the municipality with a request to begin FSD (Supervised) tests in the city. The company has already received approval to test its Full Self-Driving (Supervised) software in several Swedish municipalities, as well as on the national road network.

Sofia Bennerstål, Tesla’s Head of Public Policy for Northern Europe, confirmed that an application has been submitted for FSD’s potential tests in Jönköping.

“I can confirm that we have submitted an application, but I cannot say much more about it,” Bennerstål told the news outlet. She also stated that Tesla is “satisfied with the tests” in the region so far.

The planned tests in Jönköping would involve a limited number of Tesla-owned vehicles. Trained Tesla safety drivers would remain behind the wheel and be prepared to intervene if necessary.

Tesla previously began testing in Nacka municipality after receiving local approval. At the time, the company stated that cooperation between authorities, municipalities, and industry enables technological progress and helps integrate future transport systems into real-world traffic conditions, as noted in an Allt Om Elbil report.

If approved, Jönköping would become the latest Swedish municipality to allow local Full Self-Driving (Supervised) testing.

Tesla’s Swedish testing program is part of the company’s efforts to validate its supervised autonomous driving software in everyday traffic environments. Municipal approvals allow Tesla to gather data in urban settings that include roundabouts, complex intersections, and mixed traffic conditions.

Microsoft has announced a new collaboration with Starlink as part of its expanding digital access strategy, following the company’s claim that it has extended internet connectivity coverage to more than 299 million people worldwide.

The update was shared ahead of Mobile World Congress, where Microsoft detailed how it surpassed its original goal of bringing internet access to 250 million people by the end of 2025.

In a blog post, Microsoft confirmed that it is now working with Starlink to expand connectivity in rural and hard-to-reach regions.

“Through our collaboration with Starlink, Microsoft is combining low-Earth orbit satellite connectivity with community-based deployment models and local ecosystem partnerships,” the company wrote.

The partnership is designed to complement Microsoft’s existing work with local internet providers and infrastructure companies across Africa, Latin America, and India, among other areas. Microsoft noted that traditional infrastructure alone cannot meet demand in some regions, making low-Earth orbit satellite connectivity an important addition.

Kenya was cited as an early example. Working with Starlink and local provider Mawingu Networks, Microsoft is supporting connectivity for 450 community hubs in rural and underserved areas. These hubs include farmer cooperatives, aggregation centers, and digital access facilities intended to support agricultural productivity and AI-enabled services.

Microsoft stated that 2.2 billion people globally remain offline, and that connectivity gaps risk widening as AI adoption accelerates.

Starlink’s expanding constellation, now numbering more than 9,700 satellites in orbit, provides near-global coverage, making it one of the few systems capable of delivering broadband to remote regions without relying on terrestrial infrastructure.

Starlink is expected to grow even more in the coming years as well, especially as SpaceX transitions its fleet to Starship, which is capable of carrying significantly larger payloads compared to its current workhorse, the Falcon 9.

LG Energy Solution (LGES) will manufacture lithium iron phosphate (LFP) energy storage system (ESS) batteries for Tesla at its Lansing, Michigan facility. 

The report was initially published by TheElec, citing industry sources.

LG Energy Solution’s Lansing plant, formerly known as Ultium Cells 3, was previously operated as a joint venture with General Motors. LGES acquired GM’s stake in May 2025 and now fully owns the site. With a production capacity of 50 GWh per year, it is one of the company’s largest facilities in North America.

LG Energy Solution is converting part of the Lansing factory to produce LFP batteries for energy storage systems. Equipment orders for the new lines have already been placed, and mass production is reportedly expected to begin in the second half of next year.

Last July, LG Energy Solution disclosed a 5.94 trillion won battery supply agreement running from August 2027 to July 2030. While the company did not name the customer, industry sources pointed to Tesla as the buyer.

Tesla has primarily used CATL’s prismatic batteries for its Megapack systems. The move to source prismatic LFP cells from LG Energy Solution’s U.S. plant could then be seen as part of Tesla’s efforts to bolster its North American supply base for its energy storage business.

For the Lansing conversion, LG Energy Solution reportedly plans to use electrode equipment originally ordered under its Ultium Cells venture with General Motors. Suppliers reportedly include CIS and Hirano Tecseed for electrode systems, TSI for mixing equipment, CK Solution for heat exhaust systems, A-Pro for formation equipment, and Shinjin Mtech for assembly kits.

Tesla currently manufactures energy storage products at facilities in California and Shanghai, though another Megafactory that produces the Megapack is also expected to be built in Texas. As per recent reports, the Texas Megafactory recently advanced with a major property sale.
