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.

Countdown: America is going back to the Moon and SpaceX holds the key to what comes after
NASA’s Artemis II launches Wednesday, sending humans near the Moon for the first time since 1972.
For the first time since Apollo 17 touched down on the lunar surface in December 1972, the United States is sending humans back toward the Moon. NASA’s Artemis II mission is set to launch as early as this week from Kennedy Space Center in Florida, carrying four astronauts on a 10-day journey around the Moon and back to Earth. It will not land anyone on the surface this time, but it is the first crewed flight in over half a century to travel beyond low Earth orbit, and it sets the stage for Elon Musk’s SpaceX missions to follow.
The mission uses NASA’s Space Launch System rocket and the Orion spacecraft, which will fly around the Moon before splashing down in the Pacific Ocean around April 10. For context, an uncrewed Artemis I flew the same path in 2022, proving the hardware worked. Artemis II now tests it with people aboard.
According to NASA’s official countdown blog, launch preparations are on track with an 80 percent chance of favorable weather. “Hey, let’s go to the moon!” Commander Wiseman told reporters upon arriving at Kennedy Space Center.

Beyond Artemis II lies the lander question, and that is where SpaceX enters directly. In 2021, NASA awarded SpaceX a $2.89 billion contract to develop the Starship Human Landing System, a modified version of Starship designed to ferry astronauts from lunar orbit to the surface. The original plan called for SpaceX to deliver that lander for Artemis III, which was to be the first crewed lunar landing. Timing for Starship development, however, caused NASA to restructure the mission sequence entirely.
Before SpaceX’s Starship Human Landing System (HLS) can put anyone on the Moon, it has to solve a problem no rocket has demonstrated at scale, which is refueling in orbit. Because the Starship HLS requires approximately ten tanker launches worth of propellant loaded into a depot in low Earth orbit before it has enough fuel to reach the lunar surface, SpaceX plans to conduct this refueling process using its upgraded V3 Starship. And until that demonstration flies and succeeds, the Starship moon lander remains a question mark.
SpaceX’s Starship V3 is almost ready and it will change space travel forever
In February 2026, NASA Administrator Jared Isaacman confirmed that Artemis III, now planned for mid-2027, and will instead test lunar landers in low Earth orbit, with the actual landing pushed to Artemis IV that’s targeted for 2028.
Musk responded to earlier criticism of SpaceX’s schedule by posting on X that his company is “moving like lightning compared to the rest of the space industry,” and added that “Starship will end up doing the whole Moon mission.” The contract competition was also reopened in October 2025 by then NASA chief Sean Duffy, who cited Starship’s delays and said the agency needed speed given China’s own stated goal of landing astronauts on the Moon by 2030.
They won’t. SpaceX is moving like lightning compared to the rest of the space industry.
Moreover, Starship will end up doing the whole Moon mission. Mark my words.

Artemis came from the first Trump administration’s 2017 Space Policy Directive 1, which directed NASA to return humans to the Moon. The program picked up pace through the 2020s, with the Orion spacecraft and SLS taking years to develop at enormous costs. SpaceX entered the picture in 2021 as the chosen lander contractor, tying the commercial space sector into what had historically been an all government undertaking.
Whether SpaceX’s Starship ultimately carries astronauts to the lunar surface or shares that role with Blue Origin’s competing lander, this week’s Artemis II launch is the necessary first step. Getting four humans to the Moon’s vicinity and back safely is the proof of concept everything else depends on.

Elon Musk debunks latest rumors about SpaceX IPO
Musk has swiftly put to rest circulating reports suggesting that SpaceX would exclude popular retail brokerages Robinhood and SoFi from its highly anticipated initial public offering. In a direct response posted on X on March 31, Musk stated simply, “These reports are false,” addressing widespread speculation fueled by a Reuters article.
Tesla and SpaceX CEO Elon Musk debunked the latest rumors about the space exploration company’s initial public offering (IPO), which has been the subject of a wide array of speculation over the last few weeks.
With SpaceX likely heading to Wall Street to become a publicly-traded stock in the coming months, there is a lot of speculation surrounding how it will happen, whether the company will potentially combine with Tesla, and more.

But the latest rumors have to do with where SpaceX will list the stock.
Musk has swiftly put to rest circulating reports suggesting that SpaceX would exclude popular retail brokerages Robinhood and SoFi from its highly anticipated initial public offering.
In a direct response posted on X on March 31, Musk stated simply, “These reports are false,” addressing widespread speculation fueled by a Reuters article.

The Reuters report, published March 30, claimed that Morgan Stanley’s E*Trade was in talks to lead the sale of SpaceX shares to small U.S. investors.
Sources indicated that Robinhood and SoFi, despite pitching for roles, faced potential exclusion from the retail allocation, with Fidelity also competing for a piece of the action. The story quickly spread across financial media, raising concerns among retail investors eager to participate in what could be one of the largest IPOs in history.
SpaceX has a reported valuation nearing $1.75 trillion, and Musk’s plan to allocate up to 30 percent of shares to individual investors — far above the typical 5-10% — had generated massive excitement.
Musk’s concise denial immediately calmed the narrative. The original X post quoting the rumor garnered significant engagement, with users expressing relief that everyday investors would not be sidelined.
This episode reflects Musk’s hands-on approach to SpaceX’s public debut.
Earlier reporting revealed plans for an unusually large retail slice to leverage Musk’s dedicated fan base and stabilize post-IPO trading. SpaceX aims to file potentially as early as this period, building on momentum from its Starship program and Starlink growth.
The IPO could mark a transformative moment, potentially elevating Musk’s status further while democratizing access to a company long reserved for accredited investors and institutions.
The rumor’s quick debunking also revives debates about retail access in high-profile listings. Robinhood gained popularity during the 2021 meme-stock surge but faced criticism for past trading restrictions.
SoFi has positioned itself as a modern financial platform for younger investors. Excluding them could have limited participation from tech-savvy retail traders who form a core part of Musk’s supporter base across Tesla and SpaceX.
While details remain fluid, Musk’s intervention reinforces commitment to broad accessibility. As preparations advance, investors await official filings. For now, the message is clear: rumors of restricted retail access were overstated, keeping the door open for widespread participation in SpaceX’s public chapter.
This development comes amid broader market enthusiasm for space and technology stocks. Musk’s transparency through X continues to shape public perception, distinguishing SpaceX’s path from traditional Wall Street norms. With retail allocation potentially reaching 30 percent, the IPO promises to be both commercially massive and culturally significant.

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.
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.
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.
