SpaceX CEO Elon Musk says that the company’s first full-scale Starship prototype has completed an inaugural hop test in South Texas, igniting its lone Raptor engine and straining against a trio of tethers attached to its legs.

While relatively minor in the scope of SpaceX’s next-generation rocket program, Starhopper’s successful tethered hop now paves the way towards untethered testing in which the terminally suborbital testbed could spend several minutes aloft and reach altitudes as high as 5 km (3 mi). Aside from Starhopper itself, this perhaps marks an even more significant milestone for Raptor, completing the engine’s first successful test-fire as part of an integrated flight vehicle.

Starhopper’s first successful Raptor ignition comes after the better part of two weeks of concerted testing of the integrated prototype, beginning around March 18/19. That testing included 5+ wet dress rehearsals (WDRs) that involved loading the vehicle with a significant quantity of liquid methane and oxygen propellant, verifying the performance of avionics and plumbing, and ultimately attempting to ignite Raptor.

Ironically, less than 24 hours before Starhopper’s successful ignition, SpaceX CEO Elon Musk had noted that the rough prototype, its ground systems, or both were suffering from issues caused by ice formation in propellant valves. Reading between the lines, it’s likely that the issues involved valves on both Starhopper and its ground support equipment ‘sticking’ (i.e. failing to actuate) when commanded. While not usually a particularly large risk for the overall health of the vehicle and pad, uncooperative valves will almost invariably throw a wrench in the gears of attempted rocket operations, particularly when dealing with cryogenic propellants like those used by Starhopper.

As the supercool methane and oxygen inevitably begin to warm after leaving the propellant plant and entering Starhopper’s tanks, a fraction of the liquid will gradually transition into gas and expand, requiring constant venting of the tanks to prevent overpressure events that could damage or destroy the rocket. Falcon 9 and Heavy exhibit this same behavior, as do most other liquid-fueled rockets. This helps to explain the massive venting seen throughout Starhopper’s half-dozen or so WDR tests, as well as large but routine fireballs as excess methane gas was burned off as part of the process of vehicle and pad pressure regulation.

According to Musk, “all systems [were] green” during Starhopper’s most critical test yet. If Raptor and its prototype host are still in good health after their integrated three-second ignition test, SpaceX could attempt several more static fires and tethered hops over the next few days, mirroring the extremely rapid test series observed in February with the first completed Raptor engine.

If all proceeds nominally, it’s possible that SpaceX could begin untethered hop tests in the near future. Regardless, this marks an excellent step forward for the company’s next-generation Starship/Super Heavy spaceship and launch vehicle – all data gathered in this phase will help to optimize and improve the final design of the first orbital vehicles.

The Starship moon landing number NASA and Elon Musk can’t agree on

Musk disputes NASA estimate of 22 Starship launches for Moon landing, predicting 6 to 8.

Elon Musk is disputing a new NASA safety panel estimate of how many Starship launches it will take to put astronauts on the Moon, saying the real number will be less than half the panel’s figure.

On Thursday, NASA’s Aerospace Safety Advisory Panel held its quarterly public meeting. Panel member Charlie Precourt, a former NASA astronaut, flagged the fueling process for SpaceX’s lunar lander as a major risk for Artemis IV, the mission planned to land a crew on the Moon in 2028. “We need to keep our eyes on numerous required fuelings for the lander,” Precourt said, according to Ars Technica. “I think the last estimate is around 22 flights.”

Ars Technica’s Eric Berger posted the comment on X, and Musk replied. “That’s way too high,” Musk wrote. “Actual number will be more like 6 to 8.”

The disagreement comes down to a basic problem with sending a ship as large as Starship to the Moon. Starship burns nearly all of its propellant just reaching Earth orbit, so it cannot continue on to the Moon without stopping for a refill. SpaceX’s answer is a gas station in space. First, a Starship that works as a storage tank, called a depot, is launched into orbit. Then a series of tanker Starships launch one at a time, dock with the depot and pump their leftover propellant into it. Once the depot is full, the lunar lander version of Starship launches, docks, fills up and heads for the Moon.

Every tanker trip is its own full rocket launch, which is why the count matters. More launches mean more time, more cost and more chances for something to go wrong before astronauts ever leave Earth. Berger estimated that even if SpaceX reaches twice weekly Starship launches by the end of 2027, filling a depot at the panel’s number would still take roughly three months.

How many tankers are needed depends mostly on how much propellant each one can carry to orbit and how much is lost along the way. Starship’s fuel and oxygen are stored at extremely cold temperatures, and some of it slowly boils off while waiting in orbit. More is lost in each transfer. NASA appears to be working from what Starship can lift today, while Musk’s range assumes a more capable rocket.

Musk has pushed back on higher counts before. In 2021, after a government document suggested 16 launches, he called that “extremely unlikely” and said eight tankers would be the most required.

Much of the answer depends on hardware SpaceX has not finished flying. As Teslarati noted earlier this year, the company plans to carry out the refueling process with its upgraded V3 Starship, and Precourt described Artemis IV as carrying “a large number of firsts.” He also praised NASA Administrator Jared Isaacman’s team for working to clear obstacles for both SpaceX and Blue Origin, whose Blue Moon lander does not rely on orbital refueling for its first mission.

SpaceX confirmed the date of Starship’s 15th launch window with some massive ambitions for the mission, as it will attempt to catch Ship for the first time.

CEO Elon Musk confirmed during SpaceX’s Earnings Call last night on October 20 that it would launch Starship for its 15th test flight in November, and there are some incredible things the company wants to try, making it perhaps the most groundbreaking launch in the program’s history.

The most major development of the call was SpaceX’s intention to catch Ship alongside catching the Super Heavy Booster, something that has happened in the past. SpaceX showed an animation of the Ship catch, which will be done on the launch tower’s chopsticks:

This monumental goal is to catch both the Ship and Booster in a dual-catch scenario, an incredible feat since SpaceX has never been able to reuse a Ship after launch. Musk said it would be “the first time that an orbital launch vehicle has been fully recovered,” and said it would be a “profound technology milestone.”

Musk said the odds of success on this first Ship catch attempt are “more likely than not,” but SpaceX is ultimately prepared for more tries moving forward. The SpaceX frontman said that, starting next year, Starship would have a “steady stream” of flights through the end of the year.

The cadence will accelerate in 2027, with Musk stating the company plans to target weekly flights in the first half of 2027 and twice-weekly by year-end.

The Flight 15 attempt follows that of Flight 14, which took off in late September and was Starship’s first orbital mission. It deployed 26 Starlink V3 satellites, accomplished a controlled ocean splashdown of both stages, and shed more light on potential challenges for the program moving forward.

As of now, the Starship program is firing on all cylinders.

Investor's Corner

SpaceX stock gets a slew of price target boosts after bullish earnings call

Published

on

Wall Street analysts rapidly raised price targets on SpaceX (NASDAQ: SPCX) after the company reported a bullish third quarter for 2026 following the market close on October 20. Shares were sent sharply higher in after-hours and premarket trading.

SpaceX posted revenue of $14.6 billion, a 161 percent year-over-year increase that comfortably topped consensus estimates, which fell near $12.7 billion. The company also posted a net profit of $4.4 billion from a prior-year loss, with adjusted EBITDA reaching $8.8 billion.

Its Super Intelligence (AI) division generated roughly $7.6 billion and became the largest revenue contributor, growing nearly 830 percent year-over-year, while the Connectivity segment delivered $5.2 billion on strong subscriber additions that lifted the consumer base to 13.6 million for Starlink.

The Earnings Call proved especially catalytic, as CEO Elon Musk and CFO Bret Johnsen outlined Q1 2027 revenue guidance of $33 billion to $37 billion, which was far above the roughly $22 billion analysts had modeled, alongside fourth-quarter capital-expenditure plans of $35 billion to $40 billion focused on AI compute infrastructure at sites including Memphis and Southaven.

Management targets 2.5 to 3 gigawatts of nameplate compute capacity by year-end and discussed pathways to 13 gigawatts or more by the end of 2027. Musk described relentless demand from hyperscalers and other customers, with compute pricing supporting payback periods of less than a year and potentially as short as six months.

Additional highlights included Starship’s recent orbital success and V3 satellite deployment, Starlink pricing and enterprise momentum, rapid Grok Bot adoption, spectrum expansion plans, and the formation of special committees to explore a possible combination with Tesla.

These elements prompted a wave of price-target increases:

  • JPMorgan more than doubled its target to $500 from $240 while maintaining an Overweight rating.
  • Cantor Fitzgerald lifted its target to $345 from $246 (Overweight).
  • Barclays raised its target to $300 from $254 (Overweight).
  • Citi increased its target to $240 from $200 (Buy),
  • UBS moved to $230 from $210 (Buy), and
  • TD Cowen raised its target to $224 from $200 (Buy).
  • Morgan Stanley held an Overweight rating with a $300 target.
  • Other firms also adjusted higher, including Wells Fargo (to $274 from $214) and Clear Street (to $248 from $217). Analysts broadly cited the strong quarterly print, accelerating AI compute expansion, Starlink progress, and Starship milestones as drivers of higher long-term growth and earnings power.

Shares, which closed at $147.79 on October 20, jumped roughly 8 percent in early premarket trading on October 21 as investors digested the results and the newly elevated Street targets.

The average analyst price target has moved higher, which reflects greater conviction in SpaceX’s trajectory across launch, connectivity, and the Super Intelligence business, even as elevated spending remains a point of focus.
