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 and Nvidia team up on Musk’s orbital AI bet

SpaceX revealed a new Nvidia satellite partnership, then Musk pledged an exclusive Nvidia hardware commitment.

Published

By

SpaceX and Nvidia are now working together on the hardware that will power Musk’s orbital data center ambitions. SpaceX announced on X on Tuesday that it is partnering with Nvidia to design the compute payload for Starmind AI1, the first satellite in a planned constellation built to run AI workloads directly in orbit. Each Starmind satellite will carry Nvidia’s Rubin GPUs and Vera CPUs, according to the post, which included renderings of the payload design.

The announcement landed hours before SpaceX’s first earnings call as a public company, where Musk went further, saying the company has committed to building its AI infrastructure exclusively on Nvidia hardware. “We think the Vera Rubin architecture is the best architecture. We think it’s the best AI computer, and we greatly value our close cooperation and partnership on many levels with Nvidia,” Musk told investors on the call,. “So we’re exclusive to Nvidia.”

Musk said SpaceX plans to deploy Nvidia’s Vera Rubin NVL72 rackscale system, codenamed Kyber, both on the ground and in space. He set a target of 2 gigawatts of compute capacity online by the end of this year, scaling to roughly 10 gigawatts by the end of 2027.

SpaceX’s newest Starmind will make earth data centers obsolete

Starmind has been in development since Musk confirmed the name in June, following an xAI trademark filing that tipped off the project before SpaceX made it official. The idea is massive in scope and instead of moving data down to ground based servers, satellites equipped with onboard processors and large solar arrays would compute AI workloads in orbit and beam results back to Earth. SpaceX has already filed with the FCC for a constellation of up to one million satellites to support the effort, citing constant solar power and the absence of zoning restrictions as advantages over terrestrial data centers.

The Nvidia exclusivity marks a shift in tone from just two weeks ago, when Musk was busy knocking down a report that SpaceX had ordered $52 billion worth of Nvidia GPUs through Foxconn, calling it fake news at the time. The dollar figure in that rumor may have been wrong, but the underlying direction seems correct. SpaceX’s AI division already leases Colossus compute capacity to Anthropic and Google, and Tuesday’s earnings report showed AI revenue climbing sharply as those deals ramp up.

Nvidia shares rose roughly 3% in Tuesday trading on the news, while SpaceX stock climbed nearly 9% during the day before giving back gains after hours as investors digested the earnings report’s capital spending figures.

Elon Musk

SpaceX’s biggest test yet arrives this week and it’s not a rocket launch

Published

By

SpaceX will report second quarter results after the market closes on Tuesday, August 4, marking the first time the company has opened its books to the public since its record IPO in June. Management will host a live audio only webcast at 4:30 p.m. ET, streamed on X, with no dial in option.

The debut carries more weight than a typical first quarter as a public company. Two trading days after the release, on August 6, the first tranche of SpaceX’s lockup expires, freeing roughly 911.5 million insider and employee shares, worth well over $100 billion at current prices and the largest such release in Wall Street history. A second, larger tranche tied to the stock trading 30 percent above its $135 IPO price never triggered, since shares have spent most of July trading below that price.

Wall Street’s models point to revenue near $6.9 billion for the quarter, up sharply from the $4.69 billion SpaceX reported in the first quarter, with a narrower per share loss than the $1.27 posted three months earlier, according to estimates compiled by Motley Fool. Those numbers will be the first look at how SpaceX’s three segments, Starlink, launch and AI, are performing independently.

SpaceX scores another massive Pentagon deal to support military satellites

Investors heading into the call have a specific list of questions. How many net new Starlink subscribers did SpaceX add after ending March with 10.3 million, and is average revenue per user holding up as the service expands into lower income markets. How much of the AI segment’s revenue reflects contract signings with Anthropic, Google and Reflection AI this year, deals that combined could annualize to nearly $28 billion if fully ramped. Whether capital expenditures, which nearly doubled in the AI segment alone between 2024 and 2025, are still accelerating or starting to plateau. And whether management offers any forward guidance at all, something SpaceX has never done publicly.

The report will also land days after Elon Musk publicly denied a Wall Street Journal report describing internal planning to separate Tesla’s China business ahead of a potential Tesla-SpaceX merger. Whether Musk or SpaceX executives address that speculation on the call, even indirectly, maybe something investors will be listening for on Tuesday.

As Teslarati reported after Musk’s own warning to short sellers last week, the CEO has made clear he expects skeptics to be proven wrong over time. Tuesday will be the first chance for the numbers themselves to make that case.

Elon Musk reveals SpaceX performed secret Starship test on Flight 13

Published

SpaceX performed a secret test on a specific portion of Starship with its recent 13th test flight last week, CEO Elon Musk revealed.

Starship’s 13th test flight took place last Friday, and in many aspects, it was one of the most overwhelmingly successful launches in the project’s history.

All of the mission objectives were met without incident, both the Super Heavy Booster and Ship managed to perform safe splashdowns in the Gulf of America and the Indian Ocean, respectively, and the deployment of Starlink satellites came and went without any complications.

However, there was more on the agenda for SpaceX with Flight 13. Musk revealed an internal test of the ship’s heat shield tiles, as the space exploration company wanted to push them to the limits after previous issues.

Many noticed that Starship’s initial launch seemed to be more accelerated than normal, and that was not a mistake. Musk revealed that SpaceX decided to give Flight 13 an intentionally aggressive acceleration rate in an effort to test how well the tiles would remain attached to the ship:

SpaceX had issues with some of the heat shield tiles remaining attached early on in the Starship program. The first six test flights presented some kind of anomaly with them, so the company’s big focus with them was to figure out a way to keep them intact through the duration of the flight.

Things truly improved as Flight 10 showed that ceramic tiles generally stayed attached to the ship far better due to refined attachment, as SpaceX utilized pins instead of adhesives. Flights 10 through 13 truly showed some clear progress with the heat shield tiles, and this latest test seems to be where some real progress was noticed, especially by Musk.

The 13th Starship launch last Friday was the second with Starship V3, SpaceX’s latest and greatest iteration of the spacecraft. Goals and ambitions are getting even grander as the project continues to progress. Musk has already hinted that SpaceX will likely try to catch Starship with Flight 14.
