SpaceX and the company’s drone ship Of Course I Still Love You (OCISLY) have successfully wrapped up their second Falcon 9 recovery in less than two weeks, bringing booster B1051 back to Port Canaveral to be broken over and refurbished for a second launch.

Following its support of Crew Dragon’s thus far flawless launch debut, the booster will likely be exceptionally easy to turn around for its next flight. That second launch could occur as early as late April for Cargo Dragon’s 17th mission, a consequence of NASA’s desire to keep its SpaceX missions on boosters that are ‘in family‘ (i.e. only new boosters or flight-proven boosters that have only launched NASA payloads).

Although B1051’s reentry profile was relatively slow and gentle with main engine cut-off (MECO) and booster separation occurring at ~1.9 km/s (4250 mph) and 85 km (53 mi), its recovery was made intriguingly difficult by high seas at drone ship OCISLY’s Atlantic Ocean station. These bad conditions were readily visible at several points during SpaceX’s DM-1 livestream, with OCISLY heeling several degrees as the Falcon 9 booster’s Merlin 1D engine lit up the surrounding area like a floodlight. In fact, B1051’s post-landing struggle could actually be seen live as the booster clearly slide several meters across the drone ship’s deck almost immediately after touching down.

This issue of boosters sliding about and generally being difficult to deal with is actually one of the leading motivations that lead to SpaceX developing Octagrabber, a tank-like robot used to remotely secure recovery Falcon 9 first stages while minimizing the risk to the recovery team. In a situation like DM-1, with B1051 already sliding around OCISLY’s deck immediately after a night landing, Octagrabber would nominally be remotely activated and controlled, crawling from its garage to grab Falcon 9’s hold-down clamps and secure the stage with its own weight.

It’s actually unclear whether Octagrabber is capable of this sort of remote operation without SpaceX technicians aboard OCISLY, nor if SpaceX – as of late – has even tried to attempt to secure Falcon 9 boosters at night. The process of transferring crew between ships in heavy seas is actually quite dangerous on its own, so it would be less than surprising to hear that SpaceX’s recovery managers have cut down on nighttime operations in bad weather if Octagrabber can only be operated with crew present on OCISLY. For B1051, the drone ship, a tugboat, and crew boat GO Quest remained in the vicinity of the landing target until the following morning (still March 2nd) before beginning the ~500 km (~300 mi) trek back to Port Canaveral. Greeted by moody low-hanging clouds and scattered showers, observers were actually able to capture the rare sight – as pictured above – of Octagrabber being driven back into its blast shield/garage.

Regardless, future Commercial Crew launches – aside, perhaps, from SpaceX’s second demonstration launch (DM-2) later this year – will likely be able perform return-to-launch-site (RTLS) landings at the company’s Florida landing zones, much like Falcon 9 boosters already do after Cargo Dragon (CRS) missions. According to VP of Mission Assurance Hans Koenigsmann, B1051 had to conduct a drone ship (ASDS) recovery at sea due to NASA’s desire for conservative performance reserves to guard against the potential (and extremely unlikely) failure of one or several Merlin engines during the launch’s boost stage. In 2012, Falcon 9 suffered its first and only (known) in-flight Merlin failure, an anomaly which the rocket’s autonomously avionics perfectly dealt with to save the primary mission (Cargo Dragon’s operational debut, CRS-1). A secondary Orbcomm communications satellite sadly failed to make it to its operational orbit, however, classifying the mission as a partial failure. More recently, there have been unconfirmed hints pointing to other potential in-flight Merlin 1D failures, albeit during booster recovery attempts instead of the main boost phase. Whether or not those anomalies actually occurred, NASA is clearly all about extreme conservatism and ‘safety first’ approaches for the Commercial Crew Program (or at least SpaceX’s side of it).

SpaceX’s successful recovery of B1051 marks the company’s third launch and landing of 2019, thus far averaging a relatively slow one mission per month. While schedules can change, it currently appears that Crew Dragon’s DM-1 orbital debut will be the only SpaceX launch in March, barring Falcon Heavy’s own commercial debut occurring in the last few days of the month. According to a SpaceX representative speaking earlier this year, the company is actually aiming to equal or even surpass its 2018 record – 21 launches – in 2019, requiring a minimum average of two launches per month for the remainder of the year.

Numbers aside, SpaceX’s 2019 calendar will undoubtedly aim to surpass the number of major company milestones in a single year, a hard act to follow after 2017 and 2018. Ranging from the first operational Starlink satellite launches and the first SpaceX launch with astronauts aboard to major flight test and developmental milestones for the company’s next-gen Starship spaceship and Super Heavy booster, there are an incredible wealth of events to look forward to.

Google just picked SpaceX for its first step into orbital AI

Google will launch its first Project Suncatcher AI satellite on SpaceX’s Transporter-18 rideshare next week.

Published

Google is about to put its own AI chips into orbit for the first time, and it is paying SpaceX to get them there.

The company said Thursday that the first in-orbit test of Project Suncatcher, its research effort to find out whether space can host large-scale AI computing, will fly next week on SpaceX’s Transporter-18 rideshare mission.

The satellite, called MVP, is about the size of a refrigerator and carries four of Google’s Tensor Processing Units, the same chips Google runs in its ground data centers. Google originally planned to launch two custom satellites in 2027, but chose to move faster by integrating its chips into a satellite.

MVP’s solar panels supply about one kilowatt of power, and Google will run Gemini models on the TPUs only in bursts of roughly 15 minutes before the chips shut down so the radiators can shed heat. In a blog post, Google said its Trillium TPUs survived vibration testing that mimicked sustained launch loads of up to 10g, with individual components seeing 50 to 100g, and handled a radiation dose greater than a five year mission would deliver.

SpaceX and Google mull massive partnership on Musk’s orbital data dream: report

Next week’s flight, slated for October 1, follows a relationship that became public in May, when Teslarati reported that Google was in talks with SpaceX for a launch deal tied to orbital data centers. Google also holds a stake of roughly 6% in SpaceX.

The two companies are chasing the same idea from very different starting points. SpaceX’s own orbital compute program is built around the AI1 satellite, a roughly 70 meter structure derived from Starlink V3 hardware that is designed for 150 kW of peak compute, about 150 times the power MVP will draw. Elon Musk has brushed off concerns about crowding orbit with those satellites, and SpaceX is building its Gigasat factory in Bastrop, Texas, to produce them, targeting an annualized rate of about 1 GW of space compute by the end of 2027.

Musk also posted on X on Thursday that “the amount of compute in space will obviously round up to 100% of all compute.”

Google has been more cautious in public. Its research estimates that launch prices need to fall below about $200 per kilogram before an orbital data center can compete with a ground facility on energy cost, a threshold the company believes could be reached around the mid 2030s. The Suncatcher team has said it expects the effort to remain a project rather than a product for years, which leaves the first real test of its hardware riding on a rocket from the company with the most aggressive timeline in the field.

NASA taps SpaceX for more astronaut missions as Boeing Starliner remains grounded

NASA just gave SpaceX a $946 million contract for three more astronaut missions through 2030.

NASA has awarded SpaceX a $946 million contract modification covering three more astronaut missions to the International Space Station, according to an announcement the agency published Friday. The award adds Crew-15, Crew-16, and Crew-17 to SpaceX’s existing Commercial Crew Transportation Capability contract, bringing the agreement’s total value to $5.92 billion across 17 flights.

SpaceX confirmed the award on X, writing that it was excited for Falcon 9 and Dragon to launch NASA’s Crew-15, 16, and 17 missions to the Space Station from Florida. The new missions cover ground, launch, in orbit, and return operations, along with cargo transport and a lifeboat capability while docked at the station, and the period of performance runs through 2030.

The award follows a notice of intent NASA issued in May, when the agency first signaled it would purchase up to six additional post certification missions from SpaceX. Teslarati covered that filing at the time, noting NASA cited technical issues and schedule delays encountered by Boeing as a driving factor. Friday’s contract modification locks in three of those six missions, with the remaining three left open for NASA to award later, potentially to Boeing if Starliner clears certification.

Boeing’s CST-100 Starliner has still not flown an operational crew rotation mission for NASA. The spacecraft’s most recent crewed test flight in 2024 ended without the astronauts returning aboard Starliner, and the company has spent the time since working through thruster problems. SpaceX President Gwynne Shotwell said this week that SpaceX is not retiring Crew Dragon today, for sure, while stopping short of committing to fly it past 2030.

Crew-12 is currently docked at the space station, and NASA has said Crew-13 is targeting a launch in the coming weeks. The newly awarded Crew-15 through Crew-17 missions extend SpaceX’s role as NASA’s primary way of getting astronauts to and from orbit well into the back half of the decade, regardless of what happens with Starliner or Starship in the meantime.

New drone video shows Tesla’s Optimus Factory reaching a turning point

New drone footage shows Tesla’s dedicated Optimus factory steel frame nearing completion at Giga Texas.

Published

By

Tesla’s dedicated Optimus factory at Gigafactory Texas is closing in on a finished steel frame, according to drone footage posted Thursday afternoon by longtime site observer Joe Tegtmeyer. In the video, Tegtmeyer said structural steel assembly is now about five column grids away from reaching the building’s north perimeter beam, putting the primary skeleton in its final stretch roughly six months after Tesla broke ground on the North Campus site in late March.

Tegtmeyer’s footage shows concrete already going in on three upper floors while crews continue laying rebar and pouring grade beam footings at ground level. That kind of parallel work, steel rising at one end of the site while concrete sets at the other, is a scheduling approach Tesla used at the original Giga Texas building and appears to be repeating here to save time before the plant’s targeted 2027 production start.

Teslarati has tracked the building’s progress since Tesla confirmed construction was officially underway in May, when the first steel structure went up on what was then bare, reclaimed land. The facility is part of a more than 5.2 million square foot expansion of Giga Texas’s North Campus that Tesla has said will eventually run nearly the length of the existing vehicle factory, over 4,000 feet, while sitting somewhat narrower. Musk has pegged the long term output target at 10 million Optimus units a year once the line is running at full capacity, a volume that would dwarf the one million unit pilot line Tesla is standing up separately at its Fremont, California factory.

Tesla Giga Texas to feature massive Optimus V4 production line

The Texas facility sits alongside another major buildout on the same campus. Terafab, the joint Tesla and SpaceX chip fabrication plant that will eventually supply the silicon running Optimus units in the field. Housing robot assembly and chip production on the same grounds is a deliberate supply chain decision, cutting down on the shipping and lead time that would otherwise sit between the two.

Tesla has not given an updated timeline beyond its previously stated goal of bringing high volume Optimus production online at the site in the summer of 2027. Fremont’s smaller pilot line began mass producing the current Gen 3 robot in January, with that plant expected to build tens of thousands of units this year primarily to generate the real world data Tesla needs to refine the robot’s software before Giga Texas ramps up. Six months of visible construction progress, tracked almost entirely through Tegtmeyer’s recurring drone flights, gives the clearest outside look yet at how seriously Tesla is treating that 2027 deadline.
