SpaceX has launched its heaviest payload yet for the third time in ten months, demonstrating that it’s still finding ways to improve the performance of its mature Falcon rockets.

At 9:30 am EST, January 25th, SpaceX completed a static fire of the two-stage Falcon 9 rocket assigned to launch its next Starlink mission. Half an hour later, SpaceX confirmed that the rocket performed well and is scheduled to launch no earlier than 4:32 am EST (09:32 UTC) on Thursday, January 26th. SpaceX didn’t state the mission’s purpose, but shorthand (“sl5-2”) used in an official website URL implied that it would be the second launch for its Starlink Gen2 satellite constellation.

Flying for the ninth time, Falcon 9 booster B1067 lifted off on schedule and sent an expendable Falcon upper stage and Starlink 5-2’s 56-satellite payload on their way to space. B1067 safely touched down on a SpaceX drone ship soon after, setting it up to reach double digits later this year. The bus-sized stack of satellites was deployed in orbit soon after, completing SpaceX’s 176th consecutively successful launch since January 2017.

Eleven Teslas to orbit

56 is not an unprecedented number of satellites for a SpaceX launch or a Starlink launch. SpaceX has launched a record 143 rideshare payloads at once, and the company routinely launched 60 Starlink satellites at a time throughout 2019, 2020, and half of 2021. But those Starlink satellites were the first versions (V0.9-V1.0) of the spacecraft and weighed either 227 or 260 kilograms (500/570 lbs) apiece.

In the second half of 2021, SpaceX began launching new Starlink V1.5 satellites. Outfitted with laser links (optical terminals) and other miscellaneous upgrades, the new satellites weigh either 303, 307, or 309 kilograms (668, 676, or 681 lb) each. The heavier design forced SpaceX to slightly reduce the number of satellites each launch could carry. After some optimization, SpaceX regularly launches up to 54 Starlink V1.5 satellites per rocket, down from 60 V1.0 satellites.

The number of satellites may be smaller, but the mass of the payload launched has never been higher. SpaceX last broke Falcon 9’s payload mass record in August 2022, when it launched 54 Starlink V1.5 satellites for the first time. The payload reportedly weighed 16.7 tons (~36,800 lb), breaking the previous record of 16.25 tons by about 3%. The heaviest 60-satellite Starlink V1.0 payload weighed ~15.6 tons (~34,400 lb).

Now, Falcon 9 has launched 56 Starlink V1.5 satellites at once. SpaceX says the payload weighed 17.4 tons (~38,400 lb), crushing the company’s previous record of 16.7 tons. 17.4 tons is just shy of the weight of 11 Tesla Model 3s.

Starlink 5-2 targeted the same orbit as Starlink 5-1, which carried 54 satellites, indicating that SpaceX has likely made another iterative improvement to Falcon 9 performance. As SpaceX has gained confidence in and experience with Falcon 9, it’s been able to tweak the timing of certain launch events, raise performance limits, and reduce margins throughout the rocket. Starlink 5-2’s record payload means that SpaceX’s tweaks have collectively boosted Falcon 9’s performance by 11.5% (15.6 to 17.4 tons) in just a few years.

Gen1, V1.0, V1.5, Gen2, V2.0

Starlink 5-2 continues a trend of confusion begun by the company’s first Starlink Gen2 launch, which it deemed Starlink 5-1. The naming scheme implied that the satellites were a continuation of the company’s first constellation, Starlink Gen1, but SpaceX confirmed that they were the first Starlink Gen2 satellites. That SpaceX is launching 54 (and now 56) satellites also confirms that they are likely the same V1.5 satellites the company has been launching for 18 months.

SpaceX CEO Elon Musk has outright stated that the company could go bankrupt if it couldn’t begin launching much larger Starlink V2.0 satellites on its Starship rocket in the near future. Instead, SpaceX is doing the exact opposite and is populating its Starlink Gen2 constellation with Gen1-sized satellites. It’s unclear when SpaceX will begin launching the larger Starlink V2.0 satellites that were meant to be the mainstay of the Gen2 constellation.

Elon Musk sheds two new bits of detail on Starship after 13th test launch

Elon Musk shed two new bits of detail on Starship following its 13th test launch, which was an overwhelming success.

SpaceX launched Starship for the 13th time last Friday after two delays: one on Monday when several Raptor engines did not ignite, and another on Thursday due to unfavorable weather conditions in Starbase, Texas.

The launch was overwhelmingly successful. SpaceX was able to complete a necessary test of the heat shield tiles by increasing the acceleration of Starship from launch throughout the flight; 20 Starlink v3 satellites were released with no issue; the Super Heavy Booster landed safely in the Gulf of America, Ship successfully reignited engines while in space; and it also splashed down without incident in the Indian Ocean.

SpaceX Starship just nailed something it’s never done before

Nevertheless, more details are coming out about Starship, and Musk is doing the talking.

Starship Will Be Retrieved in the Ocean

Musk revealed on Tuesday night that Starship would be recovered by a ship in the Indian Ocean. SpaceX routinely tries to recover Starship after splashdown in an effort to find out more about the flight by examining the spacecraft afterward.

This helps engineers find out more about why things might have happened, allows them to examine any potential damage or anomalies that might have occurred, and increases the chances of an even more successful flight next time thanks to the additional information recovered.

Ship Could Have Been Caught by Tower Arms, Musk claims

Musk has already indicated that SpaceX will plan to attempt a catch of Starship with the 14th test flight. While this would be a major accomplishment, it would be an expected next step, considering the fact that the Super Heavy Booster has already been caught by the chopsticks on numerous occasions.

A ship catch would be a great indication of where SpaceX stands in terms of reusability and launch cadence. A successful catch with relatively no incidents would be a good sign that SpaceX is nearing a more frequent launch of Starship, but also that the reusability of the massive rocket would be something many would expect in the near future.

It is a necessity to make life multiplanetary.

Elon Musk updates the SpaceX timeline for Mars

Elon Musk has updated his timeline for when humans will walk on Mars and for when ships will simply get there.

The objective of getting to Mars has been one of Musk’s biggest goals since becoming a serial entrepreneur and realizing that time on Earth is limited. Musk has said several times he hopes to die on Mars, and not by impact.

Musk now believes that people will be on Mars in “roughly 5 to 7 years.” He said that a Mars lander will get there “a few years sooner.”

The response from Musk comes after NASA Administrator Jared Isaacman said that SpaceX’s biggest priority is the Moon and not Mars. Because of this, Isaacman conceded that he believes nuclear power and propulsion investments will provide “potentially the pathway with the fewest miracles required to put four people on Mars in the next 10 to 15 years.”

Of course, this is what NASA can do through taxpayer funding and nuclear investments, he added.

Musk’s grand ambitions are much more optimistic than most, and it is certainly a double-edged sword. This is not the first time timelines for Mars have been somewhat lofty, especially to those normal thinkers like you and me, not super geniuses like Musk.

SpaceX Board has set a Mars bonus for Elon Musk

In fact, the SpaceX and Tesla frontman has said on at least a dozen occasions that we could be on Mars in the coming years. Musk said 2020 would be the big year as early as 2009. In 2020, he was “highly confident” of a landing in 2026, and had even said 2024 in a best-case scenario.

The point is, the range has varied, and it’s anyone’s guess when we’ll get there. This latest adjustment to the timeline is typical of Musk, and while the Moon has seemingly taken priority over Mars, it is still worth mentioning that the ultimate goal is to make life multiplanetary, and it starts potentially with the Red Planet.

SpaceX gets an absolutely crazy price target after rough IPO

SpaceX (NASDAQ: SPCX) got an absolutely crazy price target rating from Raymond James after the company experienced a tough first few weeks following its Initial Public Offering (IPO).

Despite the tumultuous start, SpaceX has plenty of believers, and the company’s massively successful Starship launch last Friday, its 13th test flight of the massive rocket, went so smoothly that Raymond James analysts pushed its price target on the company to roughly 7 times its current trading level.

The firm officially put a “Strong Buy” rating and an $800 price target on the stock. It currently trades at around $113. Its all-time high is $225.64, reaching this trading level shortly after shares first went public.

Raymond James’ price target is tied to the firm’s confidence after Starship’s 13th test flight. Analysts at the firm said it was an incremental step that reduces engineering risks, citing the widely successful heat shield test that CEO Elon Musk recently detailed, the smooth deployment of Starlink V3 satellites, and a successful in-space engine relight.

SpaceX also managed to see Starship splash down safely in the Indian Ocean, while the Super Heavy Booster fell down to the Gulf of America with no incidents.

It is interesting to see these launches have such a tremendous impact on the stock and what investors think of it. After SpaceX initially delayed the Starship launch last week, shares fell tremendously. Most probably did not realize that the stand-down is a standard practice, especially if everything is not perfect.

The mission was initially aborted due to an issue with Raptor engines. This was resolved, and Starship launched last Friday after another delay on Thursday, which was caused by weather.

Now that analysts have seen what SpaceX launches are capable of and how impressive the feat is, firms are adjusting their price targets accordingly, making it known that they have high expectations for the space exploration company.
