SpaceX to launch world’s first geostationary propellant depot around the Moon

Published

on

As part of a SpaceX Falcon 9 launch that will send a commercial Moon lander on its way to Earth’s nearest neighbor, rideshare organizer Spaceflight Inc and propellant depot startup OrbitFab have revealed plans for the first high Earth orbit propellant depot.

Known as “Tanker-002,” the co-developed spacecraft will technically be the first propellant depot – essentially a gas station in space – to reach a geostationary orbit ~36,000 km (~22,300 mi) above the Earth’s surface. Based around a variant of Spaceflight’s brand new Sherpa OTV space tug vehicles, OrbitFab hasn’t disclosed the planned capacity of its unique GEO depot but the public specifications of Sherpa suggest that the company will be able to deliver a few hundred kilograms (300-800 lb) of hydrazine accessible via several tiny docking ports.

However, Tanker-002 isn’t interesting solely for its unique position as a tanker in GEO. How Spaceflight and OrbitFab plan to get the small spacecraft into position will be a feat of engineering and trajectory design in its own right.

Spaceflight intends to co-manifest Tanker-002 on Intuitive Machines’ IM-2 lunar lander, which is scheduled to launch no earlier than (NET) late 2022 or early 2023 on a SpaceX Falcon 9 rocket. Spaceflight’s Sherpa-ES tug and Tanker-002 will first piggyback into orbit on the IM-2 lander but will quickly part ways around four hours after liftoff. Instead of preparing to enter orbit around the Moon, Sherpa-ES will perform a small burn, tweaking its trajectory into a lunar flyby and gravity assist maneuver.

Thanks to Spaceflight’s new orbital transfer vehicle (OTV) capabilities and a first-of-its-kind trajectory developed by startup GeoJump, that slingshot around the Moon will allow Sherpa-ES and its Tanker-002 payload to enter geostationary orbit more quickly and efficiently, potentially arriving on station just a few weeks after launch. Meanwhile, the IM-2 lander will enter lunar orbit and begin a gradual descent until it’s ready to land – perhaps around the same time as Tanker-002 reaches GEO.

Above all else, OrbitFab’s Tanker-002 depot is more of a full-fidelity proof of concept. In an effort to tackle the chicken-and-egg challenge of commercial orbital propellant depots (which comes first: the refuelable spacecraft or the fuel source?), OrbitFab will be launching the tanker (much like it did Tanker-001) before any prospective customers for its propellant exist. That means that even after it reaches GEO, there are no existing spacecraft capable of being refueled by it. Given how small Tanker-002 likely is, it’s also sized to refuel a class of geostationary smallsats that are an ongoing source of study and development but only barely exist in the present day.

With any luck, OrbitFab – having secured interest and limited funding from companies like Northrop Grumman and Lockheed Martin – will have its “build it and they will come” leap of faith rewarded in coming years.

SpaceX Ax-4 Mission prepares for ISS with new launch date

SpaceX, Axiom Space, and NASA set new launch date for the Ax-4 mission after addressing ISS & rocket concerns.

SpaceX is preparing for a new launch date for the Ax-4 mission to the International Space Station (ISS).

SpaceX, Axiom Space, and NASA addressed recent technical challenges and announced a new launch date of no earlier than Thursday, June 19, for the Ax-4 mission. The delay from June 12 allowed teams to assess repairs to small leaks in the ISS’s Zvezda service module.

NASA and Roscosmos have been monitoring leaks in the Zvezda module’s aft (back) segment for years. However, stable pressure could also result from air flowing across the hatch seal from the central station. As NASA and its partners adapt launch schedules to ensure station safety, adjustments are routine.

“Following the most recent repair, pressure in the transfer tunnel has been stable,” a source noted, suggesting the leaks may be sealed.

“By changing pressure in the transfer tunnel and monitoring over time, teams are evaluating the condition of the transfer tunnel and the hatch seal between the space station and the back of Zvezda,” the source added.

SpaceX has also resolved a liquid oxygen leak found during post-static fire inspections of the Falcon 9 rocket, completing a wet dress rehearsal to confirm readiness. The Ax-4 mission is Axiom Space’s fourth private astronaut trip to the ISS. It will launch from NASA’s Kennedy Space Center in Florida on a Falcon 9 rocket with a new Crew Dragon capsule.

“This is the first flight for this Dragon capsule, and it’s carrying an international crew—a perfect debut. We’ve upgraded storage, propulsion components, and the seat lash design for improved reliability and reuse,” said William Gerstenmaier, SpaceX’s vice president of build and flight reliability.

The Ax-4 mission crew is led by Peggy Whitson, Axiom Space’s director of human spaceflight and former NASA astronaut. The Ax-4 crew includes ISRO astronaut Shubhanshu Shukla as pilot, alongside mission specialists Sławosz Uznański-Wiśniewski from Poland and Tibor Kapu from Hungary. The international team underscores Axiom’s commitment to global collaboration.

The Ax-4 mission will advance scientific research during its ISS stay, supporting Axiom’s goal of building a commercial space station. As teams finalize preparations, the mission’s updated launch date and technical resolutions position it to strengthen private space exploration’s role in advancing space-based innovation.

Sweden blocks Tesla FSD-style testing in Stockholm

It looks like FSD testing in Sweden would have to wait some time.

Tesla is putting a lot of effort into getting its Full Self Driving (FSD) system approved in territories outside North America. But while China seems to have embraced FSD fully, other countries like Sweden do not seem to be receiving Tesla’s automated driving system very well.

This became quite evident in a document from Stockholm City, which has started making the rounds online.

FSD Testing Rejected

The document, which was initially shared by X user @KRoelandschap, indicated that the Swedish Traffic Department in Stockholm had rejected Tesla’s request to start FSD testing in the city’s streets. Tesla has been demonstrating FSD in several areas across Europe, so it is not surprising that the company is also attempting to test its automated driving system in Sweden.

Unfortunately for Tesla, Sweden might prove to be a tough nut to crack. As per the City of Stockholm: 

“The Traffic Office is currently working on updating its approach to automation. At the same time, the city and the office are under heavy pressure from other ongoing innovation tests. Our ambition is to actively participate in and learn from the continued development in the field of automation.

“Based on this, and in combination with the fact that the current test is the first of its kind, which entails certain risks for both infrastructure and third parties, and that it is planned to be carried out throughout the city, the City of Stockholm considers it is currently not possible to approve the implementation of the test.”

Tesla’s Other Swedish Troubles

Sweden’s FSD testing rejection is not the only roadblock facing Tesla in the country. Since October 2023, Swedish unions have been engaged in an active effort to disrupt Tesla’s operations. The unions’ efforts have been varied, with some resulting in Tesla having difficulty launching more Superchargers in Sweden. Despite this, Tesla has remained stubborn and has refused to bow to the unions’ demands.

Fortunately for Tesla, it seems like its numbers are still strong. Despite the company’s decline in several European countries, the new Model Y is starting to see strong sales figures in Sweden. In early May alone, the new Model Y became the country’s most popular electric vehicle—a notable accomplishment considering the unions’ active efforts to disrupt Tesla.

Tesla firmware shows new Model Y seat configuration is coming

Tesla could be adding another seating configuration beside the seven-seater to the Model Y lineup later this year.

Tesla firmware has been a great place for some to reveal what the company has in the pipeline, and a new seating configuration for the best-selling Model Y looks to be on the way.

Last week, we reported that Tesla was already hinting toward a 7-seater configuration of the Model Y in a promotional email it sent to those on its contact list.

However, firmware revealed by Tesla hacker greentheonly is showing that a new seating configuration is on the way — a six-seater:

Green says the configuration would not be available in China-only, and will be potentially for sale in other markets as well.

The six-seat and seven-seat configurations of the Model Y were available in the Legacy version of the vehicle, but were met with mixed reviews, as many complained about the lack of legroom in the third row.

This was something that was a real concern for many of those owners who needed something larger than the traditional five-seat variant, but did not want to buy the much more pricey Model X.

We’ve covered the size of that third row on several occasions.

Some owners even took the idea of having a seven-seater into their own hands:

Tesla did not explicitly announce a six-seater configuration of the Model Y, but Lars Moravy, the company’s VP of Vehicle Engineering, said the seven-seater would come to production later in 2025.
