Gilmour Space looks to join the commercial rocket race
The Australian-based rocket company Gilmour Space is looking to launch its Eris orbital launch vehicle no earlier than April 2024.
Based out of Queensland, Australia, Gilmour Space has been slowly but steadily testing all of the components of its Eris rocket ahead of a planned launch this year.
The 3-stage rocket can launch up to 305 kg (672 lbs) into low Earth orbit, roughly matching Rocket Lab’s Electron rocket.
Eris stands 25 meters (82 ft) tall, with the base of the rocket being 2 meters (6 ft) in diameter before tapering to 1.5 meters for the top half of the rocket. The payload fairing can either be 1.2 or 1.5 meters in diameter.
This is #Sirius, Gilmour’s main hybrid rocket engine that will power the first and second stages of the #Eris rocket to orbit.

The first stage will be powered by 4 of the company’s Sirius hybrid rocket motors which use a proprietary solid fuel and a liquid oxidizer, a single Sirius rocket motor will power the second stage of the rocket once it reaches staging and finally the third stage will utilize their 3D printed Phoenix rocket engine which is fueled by liquid oxygen and RP-1 (rocket grade kerosene).

Over the past few years, the company has conducted many test fires of both engines including testing their Sirius hybrid rocket motor to destruction.
When the vehicle is fully integrated, the rocket will be placed onto its transporter erector and rolled to its launch pad at the Bowen Orbital Spaceport and raised vertically.
Once the company receives final approvals to attempt a launch, it will be the first orbital launch attempt from Australia since October 1971 and if successful, will be the first rocket to use a hybrid motor to reach orbit.
Gilmour Space is joining a growing market of small rocket providers, and it remains to be seen if they will be able to make an impact similar to Rocket Lab or face a fate similar to Astra. Do you think Gilmour Space will be successful in their first attempt?

SpaceX hit with mishap investigation by FAA for Starship Flight 9
Starship’s ninth test flight has the FAA requiring a mishap investigation from SpaceX.

SpaceX has been hit with yet another mishap investigation by the Federal Aviation Administration (FAA) related to the company’s ninth test flight of Starship earlier this week.
The FAA said the mishap investigation is “focused only on the loss of the Starship vehicle, which did not complete its launch or reentry as planned.” The agency said the loss of the Super Heavy booster is covered by one of the FAA’s approved test induced damage exceptions requested by SpaceX.
All of Starship and Super Heavy booster debris landed within the designated hazard areas, the FAA confirmed.
It said it activated a Debris Response Area out of an abundance of caution as the booster “experienced its anomaly over the Gulf of America during its flyback toward Texas. The FAA subsequently determined the debris did not fall outside of the hazard area. During the event there were zero departure delays, one flight was diverted, and one airborne flight was held for 24 minutes. ”
SpaceX has become accustomed to mishap investigations by the FAA, as they have been impacted by them on several occasions in the past, including on Flight 8. However, they are a precautionary measure and usually are resolved within a few weeks.
Flight 9 was one of SpaceX’s most eventful, as there were several discoveries during the launch. First, it was SpaceX’s first time reusing a Super Heavy booster, as the one utilized for Flight 9 was also used on Flight 7 in January.
Contact with the booster and Starship were both lost during Flight 9. SpaceX said the booster was lost “shortly after the start of landing burn when it experienced a rapid unscheduled disassembly approximately 6 minutes after launch.”
Meanwhile, Starship was set to make a splashdown in the Indian Ocean, but the vehicle was lost about 46 minutes into the flight, SpaceX said in a mission recap.
It was an improvement from the previous two flights, as both 7 and 8 resulted in the loss of Starship after just a few minutes. Flight 9 lasted considerably longer. These flights are also not intended to make it to Mars, despite what other reports might try to tell you.
These are ways to gain information for when SpaceX eventually tries to get Starship to Mars.

Tesla bull writes cautious note on Robotaxi launch: ‘Keep expectations well contained’
Morgan Stanley’s Adam Jonas is more cautious about Tesla’s upcoming Robotaxi launch.

Tesla analyst Adam Jonas of Morgan Stanley is telling investors to be wary of the Robotaxi details CEO Elon Musk revealed this week, after a report seemed to land on the prospective launch date of the platform in June.
Earlier this week, a report from Bloomberg indicated Tesla had internally landed on a tentative date of June 12 for its Robotaxi launch in Austin. Shortly after, Musk detailed the successful testing Tesla has already performed without anyone in the driver’s seat.
He also indicated Teslas would self-deliver to customers in June.
Analysts are now sending out investor notes on the announcement Musk made, along with the Bloomberg report. Jonas’s note is more cautious than others.
Jonas believes Tesla needs to shed more details before investors and fans of the company get too excited. He believes there is more information that could be released, but until then, he is suggesting investors “keep expectations well contained.”
He wrote:
“As is typical for highly anticipated Tesla events, we would keep expectations well contained for the (reported) June 12th Cybercab launch event in Austin. However, we would look for a continued stream of updates for the performance and growth of the network thereafter (numbers of cars, miles, trips, etc.) in the days and weeks that follow.”
The tone of Jonas’s note contradicts that of Wedbush’s Dan Ives, who believes the “golden age of autonomous” lies in Tesla’s hands. He seems to believe Tesla will come through on its June 12 launch.

Morgan Stanley’s note is slightly more
Jonas is obviously still bullish, but is much more tentative to move forward with an attitude that communicates skepticism about what Tesla has revealed.
Jonas and Morgan Stanley have a $410 price target on Tesla shares with a ‘Buy’ rating. Tesla stock is trading at around $358 at 12:15 p.m. on the East Coast.

Tesla’s apparent affordable model zips around Fremont test track
Tesla was zipping around a strange, covered, compact Model Y at Fremont this week.

Tesla was racing a compact, short, and stocky Model Y with front and rear end covers around its Fremont Factory’s test track today, potentially giving us a look at the upcoming affordable model.
On Thursday, Met God in the Wilderness on YouTube posted a flyover of the Fremont Factory, a weekly occurrence for the channel. This week’s video featured a smaller, more compact Model Y racing around the Test Track at Fremont, trailed by a Cybertruck:

While both bumpers are covered, it still seems to be a much more compact version of the Model Y. There is also the potential that this is the upcoming Model Y Performance, but it seems that this vehicle is smaller than the traditional Model Y. Tesla would not reduce its size this much for the Performance configuration.
With that, it seems more likely it is one of the affordable models.
Tesla still on track to release more affordable models in 1H25
It also plays into the idea that Tesla is planning to launch vehicles very similar to the Model Y and Model 3. During the last Earnings Call, Tesla VP of Vehicle Engineering Lars Moravy stated that the affordable models the company planned to launch would be of the same form and factor as the Model Y, indicating potentially a stripped-down version of the all-electric crossover:
“I will say it’s important to emphasize that, as we’ve said all along, the full utilization of our factories is the primary goal for these new products. And so flexibility of what we can do within the form factor and, you know, the design of it is really limited to what we can do on our existing lines rather than building new ones.”
This was essentially a read-between-the-lines moment for investors as they took it as the affordable models would not be much different than the Model Y.
This vehicle seems to fit the bill of what Moravy described: it is eerily similar to the Model Y without the lengthened front and rear. While it is still tough to determine exactly what it is, it surely does look to be something that Tesla is keeping under wraps for the short term.
