SpaceX wins NASA contract to launch Earth Observing System, but current administration has other plans
SpaceX recently snagged an $80.4 million NASA contract to launch an upcoming Earth-observing satellite sometime in 2022. That is, if the mission isn’t scrapped due to budgetary issues.
A used Falcon 9 rocket is slated to ferry the 3,748-lb. (1,700 kg) Plankton, Aerosol, Cloud, and ocean Ecosystem satellite (aka PACE) to orbit sometime in December 2022. The mission, which provides data on oceans and particles in the atmosphere, is expected to launch from Cape Canaveral Air Force Station in Florida.
Its goal: to help us better understand our home planet. SpaceX is expanding its portfolio, after receiving certification for science launches in 2016. To date, SpaceX launched a bevy of scientific satellites including Jason-3 in 2106, the Transiting Exoplanet Survey Satellite (TESS) and GRACE-FO missions in 2018, and the upcoming Sentinel 6A in Nov. 2020.
But it’s been a tough journey for PACE. The satellite has been on the chopping block several times, but managed to avoid getting the ax so far.
That’s because the Trump administration has tried to cancel the ocean-watching mission three separate times now, in an effort to reduce the Earth science budget. Each time the president has tried to cut its funding, Congress voted to support it, including authorizing $131 million for the mission in December 2019.
So NASA has moved ahead with the development of the mission, and selected SpaceX as the launch provider on Feb. 4.
“SpaceX is honored to continue supporting NASA’s critical scientific observational missions by launching PACE, which will help humanity better understand, protect and preserve our planet,” Gwynne Shotwell, SpaceX’s president and chief operating officer, said in a company statement.
PACE will focus on our planet’s oceans, the clouds, and aerosols (small air particles) in an effort to better understand phytoplankton — tiny plant-like organisms in the ocean that are the base of the food chain. These organisms can tell us a lot about how climate change is affecting the environment.
“PACE will help scientists investigate the diversity of organisms fueling marine food webs and the U.S. economy, and deliver advanced data products to reduce uncertainties in global climate models and improve our interdisciplinary understanding of the Earth system,” NASA said in a statement.
“It will also continue systematic records of key atmospheric variables associated with air quality and Earth’s climate,” officials wrote on the PACE mission’s website.
Like most plants, phytoplankton relies on chlorophyll to capture sunlight, and then using photosynthesis to turn it into chemical energy, releasing oxygen as a byproduct.

Phytoplankton are a diverse variety of species and their growth depends on the availability of things like carbon dioxide, sunlight, and nutrients. Just like their terrestrial counterparts, phytoplankton require can nutrients such as nitrate, phosphate, silicate, and calcium, depending on the species.
Other factors that influence growth rates are water temperature and salinity, water depth, wind, as well as what sort of predators are nearby.
When conditions are just right, phytoplankton populations can grow explosively, a phenomenon we call a bloom. Blooms in the ocean may cover hundreds of square kilometers and are easily spotted in satellite imagery. A bloom may last several weeks, although the life expectancy of any individual organism is rarely more than a few days.
Phytoplankton are important because they are the foundation of the aquatic food web, feeding many different creatures from other microscopic organisms to enormous, mega-ton whales.
Phytoplankton aren’t always a good thing — certain species are known to produce powerful biotoxins, like the red tide. These toxic blooms can kill marine life and ultimately people if they accidentally eat contaminated seafood or by inhaling the organisms.

PACE’s primary tool is called the Ocean Color Instrument (OCI). It will measure the color of the ocean in a broad range of wavelengths, from ultraviolet to shortwave infrared, according to NASA. The satellite will observe the Earth from an orbital perch about 420 miles (675 kilometers) above the planet. (For reference, the space station orbits at 250 miles or 400 km up.)
“The color of the ocean is determined by the interaction of sunlight with substances or particles present in seawater, such as chlorophyll, a green pigment found in most phytoplankton species,” according to the mission’s website. “By monitoring global phytoplankton distribution and abundance with unprecedented detail, the OCI will help us to better understand the complex systems that drive ocean ecology.”
PACE will be in a sun-synchronous orbit, which will allow for consistent daylight conditions for imaging. This makes it easier for scientists to compare different regions and the same regions over long periods of time — if the satellite makes it to orbit.
Today, the president released his budget request for 2021, and once again, PACE is one of two Earth science missions he wants to cancel. Will its luck hold out? Will Congress vote to approve funding for the vital satellite despite the president’s suggestion? Only time will tell.
But with many coastal states recently suffering from red tide, this satellite will be a valuable tool in scientists’ arsenal to help them better understand these tiny organisms.

SpaceX’s IPO might arrive sooner than you think
Musk has hinted for years that an eventual public offering was inevitable, though he has stressed the need to maintain operational focus. Insiders have told outlets that the CEO is pushing for a significant retail investor allocation, reportedly more than 20 percent of shares, and tighter lock-up periods to limit early selling pressure.
Elon Musk’s SpaceX is on the verge of one of the most anticipated Initial Public Offerings (IPO) in history.
However, a new report from The Information indicates the rocket and satellite giant is aiming to file its IPO prospectus with U.S. regulators as soon as this week, or early next week at the latest.
People familiar with the plans told The Information that advisers involved in the process expect the IPO could raise more than 75 billion dollars, potentially making it the largest stock market debut ever and eclipsing Saudi Aramco’s 29.4 billion dollar offering in 2019.
The filing would mark the formal start of what has long been rumored: SpaceX’s transition from a closely held private powerhouse to a publicly traded company.
The timing aligns with earlier signals.
In late February, Bloomberg reported that SpaceX was targeting a confidential IPO filing in March and a possible public listing in June, with a valuation north of 1.75 trillion dollars. At the time, the company’s private valuation hovered around 1.25 trillion dollars.
SpaceX considering confidential IPO filing this March: report
Starlink, SpaceX’s satellite internet constellation, has been the primary driver of that surge, now serving millions of customers worldwide and generating steady revenue. Recent Starship test flights and a record pace of Falcon launches have further bolstered investor confidence.

Insiders have told outlets that the CEO is pushing for a significant retail investor allocation, reportedly more than 20 percent of shares, and tighter lock-up periods to limit early selling pressure.
A June listing would give SpaceX immediate access to public capital markets at a moment when demand for space-related stocks remains high. It would also allow early employees and long-time investors to cash out portions of their stakes while giving everyday shareholders a chance to own a piece of the company behind reusable rockets, global broadband, and NASA contracts.
Of course, nothing is certain until the SEC filing appears. Market conditions, regulatory reviews, and Musk’s own schedule could still shift timelines.
Yet the latest word from The Information suggests the window has opened. If the filing lands this week, SpaceX’s roadshow could begin in earnest within weeks, setting the stage for what many analysts already call the IPO of the decade.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
Tesla, SpaceX, and xAI unveiled TERAFAB, a $25B chip factory targeting one terawatt of AI compute annually.
Elon Musk took the stage over the weekend at the defunct Seaholm Power Plant in Austin, Texas, to officially unveil TERAFAB, a $20-25 billion joint venture between Tesla, SpaceX, and xAI that he described as “the most epic chip building exercise in history by far.” The announcement marks the most ambitious infrastructure bet Musk has made since Gigafactory 1 in Sparks, Nevada, and it fuses three of his companies into a single, vertically integrated AI hardware machine for the first time.
TERAFAB is designed to consolidate every stage of semiconductor production under one roof, including chip design, lithography, fabrication, memory production, advanced packaging, and testing. At full capacity, the facility would scale to roughly 70% of the global output from the current world’s largest semiconductor foundry from Taiwan Semiconductor Manufacturing Company (TSMC).
Elon Musk’s stated goal is one terawatt of computing power annually, split between Tesla’s AI5 inference chips for vehicles and Optimus robots, and D3 chips built specifically for SpaceXAI’s orbital satellite constellation.
Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
The logic behind the merger of these three entities is rooted in a supply chain crisis Musk has been signaling for over a year. At Tesla’s Q4 2025 earnings call, he warned investors that external chip capacity from TSMC, Samsung, and Micron would hit a ceiling within three to four years. “We’re very grateful to our existing supply chain, to Samsung, TSMC, Micron and others,” Musk acknowledged at the Terafab event, “but there’s a maximum rate at which they’re comfortable expanding.” Building in-house was, in his framing, not a strategic option, but a necessity.
The space angle is where the announcement becomes genuinely unprecedented. Musk said 80% of Terafab’s compute output would be directed toward space-based orbital AI satellites, arguing that solar irradiance in space is roughly 5x greater than at Earth’s surface, and that heat rejection in vacuum makes thermal scaling viable. This directly feeds the SpaceXAI vision, which is betting that within two to three years, running AI workloads in orbit will be cheaper than doing so on the ground. The satellites, powered by constant solar energy, would effectively turn low Earth orbit into the world’s largest data center.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
Historically, this announcement threads together every major Musk initiative of the past two years: the xAI-SpaceX merger, Tesla’s $2.9 billion solar equipment talks with Chinese suppliers, the 100 GW domestic solar manufacturing push, the Optimus humanoid robot program, and Starship’s development. TERAFAB is the capstone that ties them into a single coherent architecture — chips made on Earth, launched by SpaceX, powered by Tesla solar, run by xAI, and ultimately extended to the Moon.
“I want us to live long enough to see the mass driver on the moon, because that’s going to be incredibly epic,”Musk said during the presentation.

SpaceX is quietly becoming the U.S. Military’s only reliable rocket
Space Force drops ULA for SpaceX on GPS launch after Vulcan rocket anomaly investigation halts flights.
The U.S. Space Force announced today it is switching an upcoming GPS III satellite launch from United Launch Alliance’s Vulcan rocket to a SpaceX Falcon 9, a move that is as much a reflection of Vulcan’s mounting problems as it is a validation of SpaceX’s growing dominance in national security space launch. The GPS III Space Vehicle 09, originally contracted to fly on Vulcan this month, will now target a late April liftoff on Falcon 9, marking the fourth consecutive GPS III satellite the Space Force has moved to SpaceX after contracts were originally awarded to ULA.
The immediate trigger is a solid rocket motor anomaly that occurred on February 12 during Vulcan’s USSF-87 mission. Although the payloads reached orbit and ULA declared the mission successful, the company characterized the malfunction as a “significant performance anomaly” and has since paused all military launches on Vulcan pending a root cause investigation.
“With this change, we are answering the call for rapid delivery of advanced GPS capability while the Vulcan anomaly investigation continues,” said Systems Delta 81 Commander Col. Ryan Hiserote. “We are once again demonstrating our team’s flexibility and are fully committed to leverage all options available for responsive and reliable launch for the Nation.”
The broader reality is that SpaceX’s reliability record and launch cadence have made it the path of least resistance for the Pentagon, and bodes well with Elon Musk’s plans to IPO SpaceX sometime this year. Its Falcon 9 is the most flight-proven rocket in history, and the Space Force’s Rapid Response Trailblazer program was specifically designed to enable exactly this kind of provider swap for GPS missions, and effectively building SpaceX’s flexibility into the national security launch architecture by design.
For ULA, the stakes are existential. The company entered 2026 with aspirations of finally turning a corner after years of Vulcan delays, with interim CEO John Elbon pointing to a backlog of over 80 missions as reason for optimism. Meanwhile, SpaceX’s contracts with the Space Force have given it a formal pathway to take on even more national security launches going forward.
The significance of today’s announcement extends beyond one satellite swap. It reinforces that America’s most critical space infrastructure, including GPS, missile warning, and beyond, is increasingly dependent on a single commercial provider.
