SpaceX’s surprise Falcon 9 drone ship landing explained ahead of Cargo Dragon launch

Speaking in a press briefing prior to NASA’s next Cargo Dragon launch, a SpaceX official shed some light on a surprise Falcon 9 drone ship landing planned for Wednesday, revealing the circumstances behind the unique decision.

A few days ago, it became clear that SpaceX and NASA and decided to perform a drone ship booster landing attempt after Cargo Dragon’s CRS-19 launch, an unusual trajectory compared to the more typical return-to-launch-site (RTLS) Landing Zone recoveries. Teslarati discussed this quandary earlier today.

“As it turns out, this Falcon 9 landing is a bit of mystery: it’s unclear why exactly SpaceX has decided to land the booster at sea instead of the usual Landing Zone recoveries that have followed most recent Cargo Dragon launches. Typically, the low insertion orbit (~200 km x ~390 km) and relatively low mass of Cargo Dragon (less than 10 tons or 22,000 lb) means that Falcon 9 has (literally) tons of propellant left over, giving it the margins needed to flip around, cancel out a huge amount of horizontal velocity, and boost 100+ km (62+ mi) back to shore.

Instead, new Falcon 9 booster B1058 is scheduled to land aboard drone ship OCISLY some 350 km (220 mi) downrange, an unusual distance. For reference, SpaceX’s May 2019 CRS-17 mission is the only time Falcon 9 has landed at sea after a CRS launch since CRS-8, the rocket’s first successful drone ship recovery. That scenario was forced because LZ-1/2 had coincidently been showered in Crew Dragon debris after C201 exploded during testing. Even then, OCISLY was stationed just 20 or so kilometers offshore, meaning that Falcon 9 B1056 still performed a routine Return To Launch Site (RTLS) landing in spirit.”

According to Jessica Jensen, SpaceX’s director of Dragon mission management, the actual reason behind Falcon 9 B1058’s surprise drone ship landing is relatively simple and was more or less one of the possibilities posed earlier today at Teslarati.

“[It’s] also possible that CRS-19 will follow in the footsteps of CRS-18, which sported a prototype Falcon 9 upper stage designed to push the enveloped of its orbital longevity. Falcon 9 B1056 still managed to land at LZ-1 after CRS-18, but a more ambitious follow-on test could potentially require much more propellant, accounting for the drone ship’s position further downrange “

Much as predicted, SpaceX is essentially going to perform an even more ambitious coast test, requiring significantly larger propellant margins that took away from Falcon 9’s own landing propellant budget. For whatever reason, the gray coating covering the CRS-18 upper stage’s RP-1 (refined kerosene) tank is not present on Falcon 9. Based on a picture taken of the horizontal rocket by a NASA Social CRS-19 attendee, CRS-19’s upper stage looks no different than any other.

Jensen says that the coast test will be performed for unspecified “other” customers, presumably referring to the US Air Force (USAF) and other commercial customers interested in direct-to-geostationary (GEO) launch services. Direct GEO launches require rocket upper stages to perform extremely long coasts in orbit, all while fighting the hostile vacuum environment’s temperature swings and radiation belts and attempting to prevent cryogenic propellant from boiling off or freezing solid. In simple terms, it’s incredibly difficult to build a reliable, high-performance upper stage capable of remaining fully functional after 6-12+ hours in orbit.

Although SpaceX said that the test was for “other” customers, that may well have been a cryptic way to avoid indicating that one such customer might be NASA itself. NASA is in the midst of a political battle for the Europa Clipper spacecraft’s launch contract, which is currently legally obligated to launch on NASA’s SLS rocket. Said rocket will likely cost on the order of >$2 billion per launch, meaning that simply using Falcon Heavy or Delta IV Heavy could save no less than ~$1.5 billion. Incredibly, that means that simply using a commercial launch vehicle could save NASA enough money to fund an entire Curiosity-sized Mars rover or even a majority of the cost of building a dedicated Europa lander. Such a launch would demand every ounce of Falcon Heavy’s performance, including a very long orbital coast.

Regardless of the prospective beneficiaries of SpaceX’s planned Falcon 9 upper stage test, CRS-19 is scheduled to launch no earlier than 12:51 pm EST (16:51 UTC), December 4th. High upper-level winds may delay the mission 24 hours to December 5th but for now, it remains on track for Wednesday.

Tesla Megapacks chosen for 548 MWh energy storage project in Japan

Tesla plans to supply over 100 Megapack units to support a large stationary storage project in Japan, making it one of the country’s largest energy storage facilities.

Tesla’s Megapack grid-scale batteries have been selected to back an energy storage project in Japan, coming as the latest of the company’s continued deployment of the hardware.

As detailed in a report from Nikkei this week, Tesla plans to supply 142 Megapack units to support a 548 MWh storage project in Japan, set to become one of the country’s largest energy storage facilities. The project is being overseen by financial firm Orix, and it will be located at a facility Maibara in central Japan’s Shiga prefecture, and it aims to come online in early 2027.

The deal is just the latest of several Megapack deployments over the past few years, as the company continues to ramp production of the units. Tesla currently produces the Megapack at a facility in Lathrop, California, though the company also recently completed construction on its second so-called “Megafactory” in Shanghai China and is expected to begin production in the coming weeks.

Tesla’s production of the Megapack has been ramping up at the Lathrop facility since initially opening in 2022, and both this site and the Shanghai Megafactory are aiming to eventually reach a volume production of 10,000 Megapack units per year. The company surpassed its 10,000th Megapack unit produced at Lathrop in November.

During Tesla’s Q4 earnings call last week, CEO Elon Musk also said that the company is looking to construct a third Megafactory, though he did not disclose where.

Last year, Tesla Energy also had record deployments of its Megapack and Powerwall home batteries with a total of 31.4 GWh of energy products deployed for a 114-percent increase from 2023.

Other recently deployed or announced Megapack projects include a massive 600 MW/1,600 MWh facility in Melbourne, a 75 MW/300 MWh energy storage site in Belgium, and a 228 MW/912 MWh storage project in Chile, along with many others still.

Elon Musk responds to Ontario canceling $100M Starlink deal amid tariff drama

Ontario Premier Doug Ford said, opens new tab on February 3 that he was “ripping up” his province’s CA$100 million agreement with Starlink in response to the U.S. imposing tariffs on Canadian goods.

Elon Musk company SpaceX is set to lose a $100 million deal with the Canadian province of Ontario following a response to the Trump administration’s decision to apply 25 percent tariffs to the country.

Starlink, a satellite-based internet service launched by the Musk entity SpaceX, will lose a $100 million deal it had with Ontario, Premier Doug Ford announced today.

Ford said on X today that Ontario is banning American companies from provincial contracts:

“We’ll be ripping up the province’s contract with Starlink. Ontario won’t do business with people hellbent on destroying our economy. Canada didn’t start this fight with the U.S., but you better believe we’re ready to win it.”

It is a blow to the citizens of the province more than anything, as the Starlink internet constellation has provided people in rural areas across the globe stable and reliable access for several years.

Musk responded in simple terms, stating, “Oh well.”

It seems Musk is less than enthused about the fact that Starlink is being eliminated from the province, but it does not seem like all that big of a blow either.

As previously mentioned, this impacts citizens more than Starlink itself, which has established itself as a main player in reliable internet access. Starlink has signed several contracts with various airlines and maritime companies.

It is also expanding to new territories across the globe on an almost daily basis.

With Mexico already working to avoid the tariff situation with the United States, it will be interesting to see if Canada does the same.

The two have shared a pleasant relationship, but President Trump is putting his foot down in terms of what comes across the border, which could impact Americans in the short term.
