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.

Elon Musk breaks his silence on the Starlink impact to Ukraine drones
Musk says the US military and president set Starshield limits, not SpaceX, amid Ukraine complaints.
Elon Musk says the speed limit cutting out Ukraine’s military Starlink terminals is not SpaceX’s decision. In a post on X Wednesday, Musk wrote that “Starshield systems are owned and controlled by the US government. Any limits on speed or usage are decided by the US military and ultimately POTUS.” He added that Starlink is a commercial service limited to civilian or defensive activities and “cannot be used for offensive military action, as doing so would be inappropriate for a commercial company.”
He was replying to Mykhailo Fedorov, Ukraine’s former defense minister, who had thanked Musk for restoring connectivity at speeds up to 160 km/h and said removing the Starshield limit entirely is “now critical for Ukraine’s defense.”

The complaint started Tuesday night, when Ukrainian officials said military terminals began losing service above roughly 100 mph. Presidential adviser Serhiy Beskrestnov said the defense forces got no warning and several missions were disrupted, as Teslarati reported earlier Wednesday. The 7th Rapid Reaction Corps told Reuters connections dropped for 10 to 20 seconds at speeds well below the limit, which made drones harder to control. Poland’s foreign minister, Radoslaw Sikorski, asked Musk on X whether he is “playing politics with your products again.”
That is why the Starlink and Starshield distinction matters. SpaceX introduced Starshield in 2022 as the government version of Starlink, with an initial focus on Earth observation, communications and hosted payloads. It won a Space Force contract in 2023 with a $70 million ceiling. In December 2024, the Pentagon moved Ukraine’s terminals onto Starshield, covering about 3,000 units across two contracts. Ukraine’s military connections therefore run through a service that Musk now says sits under Washington’s control.
While Musk’s post describes who holds authority, it does not infer that anyone ordered the limit, and neither SpaceX nor the US government has confirmed who set it. Ukrainian officials have pointed to the timing, which follows President Trump’s push for an energy ceasefire and Musk’s Saturday post that “Zelensky has gone too far.” The BBC noted Trump denied threatening to restrict intelligence sharing with Kyiv, and no evidence has been presented that Washington requested the cap.
The episode also revives a promise from 2025. After Poland accused him of threatening Ukraine’s access, Musk said Starlink “will never turn off its terminals” and would not be used as a bargaining chip. Poland has since supplied more than 29,000 terminals to Ukraine. Teslarati also covered Kyiv’s search for Starlink alternatives in 2025, and the latest dispute gives that search new urgency.

SpaceX brings four astronauts home after 8 months in space, and the return was flawless
SpaceX Crew Dragon Freedom returned four Crew-12 astronauts home after 237 days aboard the station.
Four Crew-12 members are back on Earth after 237 days at the International Space Station. SpaceX’s Crew Dragon Freedom splashed down in the Pacific Ocean about 50 miles west of Los Angeles at 11:34 a.m. ET on Thursday.
NASA astronauts Jessica Meir and Jack Hathaway, ESA astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev landed one day after undocking from the station’s Harmony module at 8:05 a.m. ET on Wednesday. NASA confirmed the splashdown minutes later. SpaceX had flagged the 27.5 hour trip home on X while Dragon was still firing its departure burns away from the station.
The descent ran on schedule when Freedom started a nine minute deorbit burn at 10:46 a.m. ET, then hit the thicker atmosphere about 36 minutes later at nearly five miles per second. Chutes deployed at around 18,000 feet, and four main parachutes brought the capsule down to roughly 15 mph at splashdown.
SpaceX fast boats secured Dragon before the recovery ship Shannon hoisted it onto the deck with the crew still inside. Flight surgeons on board ran initial medical checks. All four crew members will be flown ashore by helicopter and then head to NASA’s Johnson Space Center in Houston for rehabilitation.

Crew-12 launched on February 13 from Space Launch Complex 40 at Cape Canaveral, a flight that also marked the first Falcon 9 booster landing at SpaceX’s new LZ-40 pad. Over the mission, the crew completed 3,792 orbits, covered nearly 101 million miles, and carried out four spacewalks to maintain and upgrade the station.
Meir now has 440 cumulative days in space, which places her in NASA’s top 10. This was the first spaceflight for Hathaway and for Adenot, a French Air Force colonel and former helicopter pilot. Fedyaev, who spent 186 days in orbit on Crew-6 in 2023, has now flown two long duration Dragon missions.
The return closes out a busy stretch of Dragon traffic. Crew-13 arrived on October 1 aboard Crew Dragon Grace, which docked just 7 hours and 55 minutes after liftoff, the fastest launch to docking of any U.S. spacecraft in ISS history. Commander Jessica Watkins, pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk, and cosmonaut Sergey Teteryatnikov remain aboard alongside the three person Soyuz MS-29 crew.
With Crew-12 gone, the port is clear for CRS-35, a cargo Dragon carrying the final pair of ISS Roll-Out Solar Arrays. NASA is holding a post-splashdown teleconference at 1:15 p.m. ET covering both the crew’s return and the upcoming cargo launch.

Elon Musk shuts down talk of TSMC taking over Terafab
Musk says Tesla and SpaceX will build and run Terafab, with TSMC limited to renting.
Elon Musk has drawn a firm line around who will be in charge of Terafab, the giant chip factory Tesla and SpaceX are planning in Texas.
Musk replied to a post on X arguing that Taiwan Semiconductor Manufacturing Company (TSMC) would most likely end up owning and operating the plant. “No, we will build and run the fab. Let there be ZERO doubt about that,” Musk wrote. “Maybe TSMC subleases part of the Terafab if they want, but nothing more than that.”
In plain terms, a sublease means TSMC could rent a section of the complex to make chips, similar to a tenant renting one floor of an office tower. The building, the equipment decisions and the daily operation would stay with Tesla and SpaceX.
@herbertong @thejefflutz No, we will build and run the fab. Let there be ZERO doubt about that.
Maybe TSMC subleases part of the Terafab if they want, but nothing more than that.
— Elon Musk (@elonmusk) October 7, 2026
The comment shuts down speculation that started last week. On October 2, tech journalist Tim Culpan reported that TSMC was exploring ways to help run Terafab’s factories. Musk responded the next day that it was “just discussions, but something may come of it,” as Teslarati reported at the time. That left room for a scenario where the world’s largest contract chipmaker took the wheel. Musk’s latest post closes that door.
Some background helps explain why this matters. Tesla designs its own AI chips today but pays outside companies like TSMC and Samsung to manufacture them. Musk unveiled Terafab in March as a joint project between Tesla, SpaceX and xAI, arguing that existing suppliers cannot expand fast enough to meet his companies’ future demand. The goal is to produce enough chips each year to supply one terawatt of computing power, roughly 50 times what the entire global AI chip industry produces now.
Those chips are meant for Tesla’s Optimus humanoid robots, the Cybercab and Full Self-Driving computers, along with chips for SpaceX’s planned data centers in orbit. Owning the factory means Musk’s companies would not have to compete with every other chip customer for time on someone else’s production lines.
Intel is still part of the picture. The company signed on in April to help design, build and package chips for the project, and CEO Lip-Bu Tan told Bloomberg this week that Intel will keep working on Terafab despite the TSMC chatter.
The project moved from concept to construction planning over the summer. In August, SpaceX confirmed the Grimes County site about an hour from Houston, sent the county a $10 million payment under its tax abatement deal and said civil work would begin shortly. The first phase carries a $16.8 billion price tag, and total spending across all phases could reach as much as $119 billion.
TSMC chairman C.C. Wei has said a new fab typically takes two to three years to build and another one to two years to reach full output. Tesla and SpaceX have never run one, which is why TSMC’s expertise drew so much attention. Musk’s answer suggests he would rather learn that process in house than hand control of a project this central to Tesla’s robotics and autonomy plans to an outside company.
Terafab Texas will be the largest and most valuable building on Earth by far.
And it will be stunningly beautiful. https://t.co/4NweOqTL7y
