Venus, Triton, or Io? Where would you send NASA’s newest mission?

The space agency is in the midst of planning out its next Discovery class mission, a lower cost exploration program, capped at $500 million (not including launch costs). To that end, NASA has selected four finalists and one — or perhaps two — will ultimately be chosen from the quartet to make it to the launch pad.

“These selected missions have the potential to transform our understanding of some of the solar system’s most active and complex worlds,” Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate, said in a statement Thursday (Feb. 13), when the finalists were announced.

“Exploring any one of these celestial bodies will help unlock the secrets of how it, and others like it, came to be in the cosmos,” he added.

The teams behind the four mission concepts will each receive $3 million to continue developing their ideas over the next nine months. NASA officials will then evaluate the prospects and select up to two missions for continued development.

In previous years, many of the choices were either very asteroid heavy or Mars centric. But this year, its Venus’ turn. Two of the four mission concepts are all about exploring Earth’s so-called hellish twin.

The DAVINCI Plus (Deep Atmosphere Venus Investigation of Noble gases, Chemistry and Imaging Plus) mission would send a probe down through the thick Venusian air, in an effort to better understand how the planet’s atmosphere has changed over time.

The VERITAS (Venus Emissivity, Radio Science, InSAR, Topography and Spectroscopy) mission would map Venus’ surface in detail from orbit. These measurements would help scientists deduce whether or not Venus has plate tectonics as we see on Earth and if there are active volcanoes on the planet’s surface.

Shifting the focus to another volcano world, the Io Volcano Observer (IVO) mission, would focus on the Jovian moon, Io, and observe it up close through a series of close flybys.

We know that Io’s volcanism is driven in part by the other Galilean moons pulling and tugging on the rocky moon, which keeps its insides churning. But what researchers don’t know is exactly how these tidal forces affect the evolution of rocky bodies. Here’s where IVO comes in.

Lastly, there’s the Trident mission. This mission would be set up similar to the New Horizons flyby of Pluto in 2015. The spacecraft would fly by Neptune’s largest moon, Triton, and study is up close, mapping the surface and trying to gauge whether or not the moon is hiding a subsurface ocean.

Established in 1992, NASA’s Discovery Program has supported the development and implementation of over 20 missions and instruments. Some of those missions include the Kepler space telescope, the Mars InSight Lander, the Dawn spacecraft that explored the dwarf planet Ceres and many more.

Tesla China delivery centers look packed as 2025 comes to a close

Needless to say, it appears that Tesla China seems intent on ending 2025 on a strong note.

Tesla’s delivery centers in China seem to be absolutely packed as the final days of 2025 wind down, with photos on social media showing delivery locations being filled wall-to-wall with vehicles waiting for their new owners. 

Needless to say, it appears that Tesla China seems intent on ending 2025 on a strong note.

Full delivery center hints at year-end demand surge

A recent image from a Chinese delivery center posted by industry watcher @Tslachan on X revealed rows upon rows of freshly prepared Model Y and Model 3 units, some of which were adorned with red bows and teddy bears. Some customers also seem to be looking over their vehicles with Tesla delivery staff. 

The images hint at a strong year-end push to clear inventory and deliver as many vehicles as possible. Interestingly enough, several Model Y L vehicles could be seen in the photos, hinting at the demand for the extended wheelbase-six seat variant of the best-selling all-electric crossover. 

Strong demand in China

Consumer demand for the Model Y and Model 3 in China seems to be quite notable. This could be inferred from the estimated delivery dates for the Model 3 and Model Y, which have been extended to February 2026 for several variants. Apart from this, the Model Y and Model 3 also continue to rank well in China’s premium EV segment

From January to November alone, the Model Y took China’s number one spot in the RMB 200,000-RMB 300,000 segment for electric vehicles, selling 359,463 units. The Model 3 sedan took third place, selling 172,392. This is quite impressive considering that both the Model Y and Model 3 are still priced at a premium compared to some of their rivals, such as the Xiaomi SU7 and YU7. 

With delivery centers in December being quite busy, it does seem like Tesla China will end the year on a strong note once more.

Tesla Giga Berlin draws “red line” over IG Metall union’s 35-hour week demands

Factory manager André Thierig has drawn a “red line” against reducing Giga Berlin’s workweek to 35 hours, while highlighting that Tesla has actually increased its workers’ salaries more substantially than other carmakers in the country.

Tesla Giga Berlin has found itself in a new labor dispute in Germany, where union IG Metall is pushing for adoption of a collective agreement to boost wages and implement changes, such as a 35-hour workweek. 

In a comment, Giga Berlin manager André Thierig drew a “red line” against reducing Giga Berlin’s workweek to 35 hours, while highlighting that Tesla has actually increased its workers’ salaries more substantially than other carmakers in the country.

Tesla factory manager’s “red line”

Tesla Germany is expected to hold a works council election in 2026, which André Thierig considers very important. As per the Giga Berlin plant manager, Giga Berlin’s plant expansion plans might be put on hold if the election favors the union. He also spoke against some of the changes that IG Metall is seeking to implement in the factory, like a 35-hour week, as noted in an rbb24 report. 

“The discussion about a 35-hour week is a red line for me. We will not cross it,” Theirig said.  

“(The election) will determine whether we can continue our successful path in the future in an independent, flexible, and unbureaucratic manner. Personally, I cannot imagine that the decision-makers in the USA will continue to push ahead with the factory expansion if the election results favor IG Metall.”

Giga Berlin’s wage increase

IG Metall district manager Jan Otto told the German news agency DPA that without a collective agreement, Tesla’s wages remain significantly below levels at other German car factories. He noted the company excuses this by referencing its lowest pay grade, but added: “The two lowest pay grades are not even used in car factories.”

In response, Tesla noted that it has raised the wages of Gigafactory Berlin’s workers more than their German competitors. Thierig noted that with a collective agreement, Giga Berlin’s workers would have seen a 2% wage increase this year. But thanks to Tesla not being unionized, Gigafactory Berlin workers were able to receive a 4% increase, as noted in a CarUp report. 

“There was a wage increase of 2% this year in the current collective agreement. Because we are in a different economic situation than the industry as a whole, we were able to double the wages – by 4%. Since production started, this corresponds to a wage increase of more than 25% in less than four years,” Thierig stated.

Tesla is seeing a lot of momentum from young Koreans in their 20s-30s: report

From January to November, young buyers purchased over 21,000 Teslas, putting it far ahead of fellow imported rivals like BMW and Mercedes-Benz.

Tesla has captured the hearts of South Korea’s 20s-30s demographic, emerging as the group’s top-selling imported car brand in 2025. From January to November, young buyers purchased over 21,000 Teslas, putting it far ahead of fellow imported rivals like BMW and Mercedes-Benz. 

Industry experts cited by The Economist attributed this “Tesla frenzy” to fandom culture, where buyers prioritize the brand over traditional car attributes, similar to snapping up the latest iPhone.

Model Y dominates among young buyers

Data from the Korea Imported Automobile Association showed that Tesla sold 21,757 vehicles to the 20s-30s demographic through November, compared to BMW’s 13,666 and Mercedes-Benz’s 6,983. The Model Y led the list overwhelmingly, with variants like the standard and Long Range models topping purchases for both young men and women.

Young men bought around 16,000 Teslas, mostly Model Y (over 15,000 units), followed by Model 3. Young women followed a similar pattern, favoring Model Y (3,888 units) and Model 3 (1,083 units). The Cybertruck saw minimal sales in this group.

The Model Y’s appeal lies in its family-friendly SUV design, 400-500 km range, quick acceleration, and spacious cargo, which is ideal for commuting and leisure. The Model 3, on the other hand, serves as an accessible entry point with lower pricing, which is valuable considering the country’s EV subsidies.

The Tesla boom

Experts described Tesla’s popularity as “fandom culture,” where young buyers embrace the brand despite criticisms from skeptics. Professor Lee Ho-geun called Tesla a “typical early adopter brand,” comparing purchases to iPhones.

Professor Kim Pil-soo noted that young people view Tesla more as a gadget than a car, and they are likely drawn by marketing, subsidies, and perceived value. They also tend to overlook news of numerous recalls, which are mostly over-the-air software updates, and controversies tied to the company.

Tesla’s position as Korea’s top import for 2025 seems secured. As noted by the publication, Tesla’s December sales figures have not been reported yet, but market analysts have suggested that Tesla has all but secured the top spot among the country’s imported cars this year.
