Future Mars astronauts’ diet will likely include space lettuce
Elon Musk wants to send a million people to Mars, and we would love to see that happen sooner rather than later.
But what will we feed them?
Since 2014, NASA has been busy studying the development of different types of plants on the space station. Using a special plant-growth chamber, called Veggie, the agency is trying to perfect the art of making space salad.
A new study published last week in the journal Frontiers in Plant Science explains that lettuce grown in space is as nutritious and tasty as any variety grown on Earth.
“The ability to grow safe, fresh food to supplement packaged foods of astronauts in space has been an important goal for NASA,” reads the paper.
Currently, astronauts on the space station rely on prepackaged food to sustain them during their time on orbit. (They also enjoy occasional treats sent up on cargo resupply missions, such as fresh fruit.) But with the help of plant chambers like Veggie, astronauts could one day crunch on healthy salads.
Packaged foods are nutritious enough, but do not have everything a person needs (or wants). The ability to have fresh fruits and vegetables on Mars could do wonders for an astronaut’s health. Not only do plants provide key nutrients, but they could also help life-support systems on any potential Mars city by helping to scrub carbon dioxide from the atmosphere.
NASA and other space agencies around the world have been studying plants in space almost as long as we’ve been sending astronauts to space. But with the construction of the space station and advent of the veggie chamber, the research can track growth over longer periods and with more crops.
Organisms grow differently in space, so understanding how plants respond to microgravity is an important step toward ensuring that future astronauts will have the ability to grow their own crops in space, especially as we start sending humans back to the moon and onto Mars.
From 2014 to 2016, researchers sent batches of “Outredgeous” red romaine lettuce seeds to space, to see if and how well they grew inside the Veggie chamber. In space there’s no gravity or soil or rain like the plants here on Earth rely on. There’s also 16 sun rises and sun sets in space, so the crops will need steady light to help them grow. Where does that come from?
The Veggie chamber is outfitted with special LED lights, tuned to a specific wavelength in order to help the plants grow. (Set to 16 hours of light and 8 hours of darkness.) Plant pillows are placed in the chamber, each equipped with its own water supply, fertilizer, and seeds. The astronauts can control the amount of water each plant receives and other settings like humidity.
The lettuce plants were allowed to grow for approximately one month before being harvested and sent back to Earth for testing. (Yes, the astronauts were allow to eat some, after they were deemed safe.)
When compared to ground-based experiments, researchers found that the crops contained the same level of nutrients that the terrestrial crops did. (Not to mention the same microbes.) The only recorded differences was a slight variation in mineral content, in particular in iron, potassium, and zinc.

SpaceX reportedly mulling IPO, eyeing largest of all time: report
“I do want to try to figure out some way for Tesla shareholders to participate in SpaceX. I’ve been giving a lot of thought to how to give people access to SpaceX stock,” Musk said.
SpaceX is reportedly mulling an initial public offering, eyeing what would be the largest valuation at the time of availability of all time, a new report from Bloomberg said on Tuesday.
It is one of many reports involving one of Elon Musk’s companies and a massive market move, as this is not the first time we have seen reports of an IPO by SpaceX. Musk himself has also dispelled other reports in the past of a similar nature, including an xAI funding round.
SpaceX and Musk have yet to comment on the report. In the past, untrue reports were promptly replied to by the CEO; this has not yet gained any response, which is a good sign in terms of credibility.
However, he said just a few days ago that stories of this nature are inaccurate:
“There has been a lot of press claiming SpaceX is raising money at $800B, which is not accurate. SpaceX has been cash flow positive for many years and does periodic stock buybacks twice a year to provide liquidity for employees and investors. Valuation increments are a function of progress with Starship and Starlink and securing global direct-to-cell spectrum that greatly increases our addressable market. And one other thing that is arguably most significant by far.”

Musk has discussed a potential IPO for SpaceX in recent months, as the November 6 shareholder meeting, as he commented on the “downsides” of having a public company, like litigation exposure, quarterly reporting pressures, and other inconveniences.
Nevertheless, Musk has also said he wants there to be a way for Tesla shareholders to get in on the action. At the meeting in early November, he said:
“I do want to try to figure out some way for Tesla shareholders to participate in SpaceX. I’ve been giving a lot of thought to how to give people access to SpaceX stock.”
Additionally, he added:
“Maybe at some point., SpaceX should become a public company despite all the downsides of being public.”
Musk has been historically reluctant to take SpaceX public, at times stating it could become a barrier to colonizing Mars. That does not mean it will not happen.
Bloomberg’s report cites multiple unidentified sources who are familiar with the matter. They indicate to the publication that SpaceX wants to go public in mid-to-late 2026, and it wants to raise $30 billion at a valuation of around $1.5 trillion.
This is not the first time SpaceX has discussed an IPO; we reported on it nine years ago. We hope it is true, as the community has spoken for a long time about having access to SpaceX stock. Legendary investor Ron Baron is one of the lucky few to be a SpaceX investor, and said it, along with Tesla, is a “lifetime investment.”

The primary driver of SpaceX’s value is Starlink, the company’s satellite internet service. Starlink contributes 60-70 percent of SpaceX’s revenue, meaning it is the primary value engine. Launch services, like Falcon 9 contracts, and the development of Starship, also play supporting roles.
SpaceX reached an incredible milestone with its Starlink program with a launch last night, as the 3,000th satellite of the year was launched into low Earth orbit.
On Monday, SpaceX also achieved its 32nd flight with a single Falcon 9 rocket from NASA’s Kennedy Space Center.
The mission was Starlink 6-92, and it utilized the Falcon 9 B1067 for the 32nd time this year, the most-used Falcon booster. The flight delivered SpaceX’s 3000th Starlink satellite of the year, a massive achievement.
There were 29 Starlink satellites launched and deployed into LEO during this particular mission:

SpaceX has a current goal of certifying its Falcon boosters for 40 missions apiece, according to Spaceflight Now.
The flight was the 350th orbital launch from the nearby SLC-40, and the 3,000 satellites that have been successfully launched this year continue to contribute to the company’s goal of having 12,000 satellites contributing to global internet coverage.
There are over five million users of Starlink, the latest data shows.
Following the launch and stage separation, the Falcon 9 booster completed its mission with a perfect landing on the ‘Just Read the Instructions’ droneship.
The mission was the 575th overall Falcon 9 launch, highlighting SpaceX’s operational tempo, which continues to be accelerated. The company averages two missions per week, and underscores CEO Elon Musk’s vision of a multi-planetary future, where reliable connectivity is crucial for remote work, education, and emergency response.
As Starlink expands and works toward that elusive and crucial 12,000 satellite goal, missions like 6-92 pave the way for innovations in telecommunications and enable more internet access to people across the globe.
With regulatory approvals in over 100 countries and millions of current subscribers, SpaceX continues to democratize space, proving that reusability is not just feasible, but it’s also revolutionary.

Tesla Cybertruck fleet takes over at SpaceX’s Starbase
Interestingly, the Cybertruck uses the same exterior, a stainless steel alloy, as SpaceX rockets. This synergy between the two companies and their very different products shows a very unified mentality between Musk companies.
Tesla Cybertrucks have taken over at SpaceX’s Starbase facility in Texas, as hundreds of the all-electric pickup trucks were spotted late last week rounding out a massive fleet of vehicles.
The Cybertruck fleet is geared toward replacing gas vehicles that are used at Starbase for everyday operations. The only surprise about this is that it was not done sooner:

Deliveries have been going on for a few weeks, as Cybertrucks have made their way across the state of Texas from Austin to Starbase so they could be included in SpaceX’s fleet of vehicles at the facility.
Interestingly, the Cybertruck uses the same exterior, a stainless steel alloy, as SpaceX rockets. This synergy between the two companies and their very different products shows a very unified mentality between Musk companies.
However, there are some other perspectives to consider as SpaceX is utilizing such a massive fleet of Cybertrucks. Some media outlets (unsurprisingly) are seeing this as a move of weakness by both Tesla and SpaceX, as the aerospace company is, in a sense, “bailing out” lagging sales for the all-electric pickup.
It’s no secret that Tesla has struggled with the Cybertruck this year, and deliveries have been underwhelming in the sense that the company was anticipating between 1 million and 2 million orders for the vehicle before it was widely produced.
A lot of things changed with the Cybertruck between its 2019 unveiling and 2023 initial deliveries, most notably, price.
The price of the Cybertruck swelled significantly and priced out many of those who had pre-ordered it. Some have weighed the option of whether this purchase was a way to get rid of sitting inventory.
However, it seems more logical to consider the fact that SpaceX was likely always going to transition to Teslas for its fleet, especially at Starship, at some point.
It doesn’t seem out of the question that one Musk company would utilize another Musk company’s products, especially considering the Cybertruck has been teased as the vehicle that would be present on Mars.
