On its fifth launch of 2020, SpaceX has nailed its 50th Falcon rocket booster landing and sent Cargo Dragon (Dragon 1) en route to the International Space Station (ISS) on its final mission, paving the way for Crew Dragon’s imminent takeover.

At 11:50 pm EST (4:50 UTC), a flight-proven Falcon 9 booster and twice-flown Cargo Dragon spacecraft lifted off from SpaceX’s LC-40 Cape Canaveral Air Force Station (CCAFS) launch pad, sending the Dragon 1 spacecraft on its third and final orbital launch. Things went as planned and the booster nailed its second landing, coming to a rest at Landing Zone-1 (LZ-1), while Falcon 9’s second stage successfully placed Dragon in orbit and deployed the vehicle. Now safely in orbit with both solar arrays deployed, Cargo Dragon will use built-in maneuvering thrusters to tweak its orbit, ultimately rendezvousing with space station no earlier than the morning (EDT) of March 9th.

Hopefully wrapping up a decade of success, the CRS-20 mission will be SpaceX’s last under NASA’s Commercial Resupply Services (CRS) Phase 1 contract, marking Cargo Dragon’s 20th successful space station rendezvous and 19th operational resupply mission. Over those 19 CRS missions, SpaceX – once CRS-20 has safely berthed – will have delivered nearly 45 metric tons (100,000 lb) of cargo to the space station and returned another 31 metric tons (>70,000 lb) to Earth, remaining the only operational spacecraft capable of doing so. While Dragon 1 will cease operations after capsule C112’s planned reentry and splashdown sometime next month, the vast wealth of expertise SpaceX has derived has already been funneled directly into Crew Dragon (Dragon 2), its successor.

Carrying about 2050 kg (4500 lb) of cargo, Cargo Dragon capsule C112 and its expendable trunk section will spend about a month in orbit after berthing with the space station this Monday. The mission may be the last time in history a SpaceX spacecraft berths with the International Space Station, a process that the Dragon 2 spacecraft will soon replace outright once it takes over. Instead of berthing, which refers to the process of astronauts manually ‘grappling’ a visiting vehicle with the space station’s massive robotic arm, SpaceX’s next-generation spacecraft relies on docking, meaning that it does all the work itself.

Docking is thus somewhat riskier and more technically challenging, but it also requires far less input from the station’s crew and can be done almost entirely autonomously, further simplifying the rendezvous process. Once it gets to that point, SpaceX’s massive Starship spacecraft will likely rely on the same docking technology if or when it comes time for it to mate with the ISS – the vehicle is simply too big for anything else.

A slightly tweaked version of Crew Dragon, SpaceX’s future Cargo Dragon 2 spacecraft will replace its human passengers with the same supplies Cargo Dragon currently ferries to and from the ISS. According to Vice President of Build and Build Reliability Hans Koenigsmann, SpaceX has already begun building its first Cargo Dragon 2 spacecraft back at its Hawthorne, California headquarters. That vehicle’s launch debut is scheduled no earlier than (NET) “fall” 2020 and will support CRS-21, SpaceX’s first NASA resupply mission under its CRS Phase 2 contract.

Cargo Dragon 2’s “launch debut” should thankfully be quite the non-event. Crew Dragon – nearly identical – will have hopefully flown at least two (and perhaps three) orbital missions to the space station by then, dramatically reducing risk. The spacecraft will also use Falcon 9, currently classed as one of the world’s most reliable launch vehicles. CRS-20 marked the rocket’s 54th consecutively successful launch, as well as SpaceX’s 50th successful booster landing since December 2015.

B1059 touched down for the first time on December 5th, 2019, coming to a rest on drone ship Of Course I Still Love You (OCISLY). 91 days later, B1059 completed its second launch and landing (CRS-20). (SpaceX)

For now, though, Cargo Dragon C112 still needs to make its way uphill to rendezvous with the ISS for the final time. Stay tuned for updates on the spacecraft’s last orbital mission.

SpaceX tells the FCC that Starship Flight 14 is going to orbit

SpaceX filed with the FCC for Starship Flight 14, its first true orbital launch attempt.

Published

on

By

SpaceX has asked the Federal Communications Commission for permission to fly Starlink terminals during Starship’s fourteenth flight test, and the filing lays out a genuine trip to orbit, something the program has never attempted.

Every Starship flight so far, including Flight 13’s successful splashdown in the Indian Ocean on July 24, has flown a suborbital arc that ends with the ship reentering the atmosphere within the same hour it launches. The FCC paperwork describes a mission profile built around an actual orbital insertion instead.

The payload is the other half of the story. Flight 13 carried 20 production Starlink V3 satellites, but because that mission never reached orbit, the satellites reentered along with the ship rather than joining the constellation, something Teslarati covered in detail after SpaceX released footage shot from one of those satellites as it drifted away from Starship in space. Flight 14 is designed to close that gap. If the orbital insertion holds, the roughly 20 V3 satellites onboard would separate into an operational orbit and could eventually go into service, each one rated for about 1 terabit per second of downlink capacity by SpaceX’s own account.

SpaceX announces new Starbase for ‘thousands of Starship launches annually’

Elon Musk first flagged the orbital attempt during SpaceX’s August 4 earnings call, the company’s first as a public entity following its June IPO under the ticker SPCX. He also floated catching the ship with the Starbase tower on the same flight, an idea he walked back on August 20, saying the catch attempt would more likely come “in a few months,” as Teslarati reported at the time. Flight 14 will instead target a splashdown for the ship in the Indian Ocean, the same recovery method used since Flight 12.

Hardware has been catching up to the ambition. Booster 21 completed a full 33-engine static fire on August 28, and Ship 41 finished its own six-engine test the week before. An airspace briefing circulated to pilots on August 20 listed September 15 as the target date, later than the end of August window Musk mentioned on the earnings call, though SpaceX has not confirmed a launch date publicly and Starship schedules routinely slip while hardware and FAA paperwork line up.

The FCC filing itself does not guarantee a launch date. It covers communications authority, and not flight readiness, considering SpaceX still needs Ship 41 fully stacked and cleared by the FAA before Flight 14 can fly. But the filing is a real marker of intent and it puts a specific regulatory process behind what had so far only been Musk’s word on the earnings call.

Tesla Cybercab Event: what to expect from Austin

Published

on

Credit: Tesla

Tesla is set to launch Cybercab on Thursday at an event in Austin, Texas, which will officially bring the company’s first steering wheel-less and pedal-less vehicle to a limited number of consumers for the first time.

The event, which is invite-only, is still thin on details: we’ll be there, and it seems the event will be held at Gigafactory Texas, but the launch of this vehicle truly relies on it being operational outside of the factory and on public roads.

Nevertheless, there are some big things to expect, and other things to temper expectations on. For what it’s worth, we believe this event could be perhaps the biggest indication that Tesla is ready to truly enter a new phase and chapter in its historic story.

Tesla Cybercab’s First Foray into the Public with Real-World Riders

Cybercab will likely hit the streets of Austin and the surrounding areas, likely in the established geofence that Tesla has expanded on for the past 14 months. Just yesterday, Tesla expanded it once again by 9 percent.

Tesla will put, for the first time, a vehicle without any manual controls on public roads, likely without any help from teleoperators. This is a truly groundbreaking development if it comes through in this fashion: it would be groundbreaking for Tesla to roll out a truly driverless ride-hailing vehicle.

Cybercab Has Already Been Unveiled

This is not an unveiling event. Cybercab has been released for nearly two years, as Tesla first showed it to the public on October 10, 2024.

FIRST LOOK: Tesla ‘Cybercab’ Robotaxi makes its global debut

While there is some small speculation that Tesla could release the Roadster at the event as a surprise, it seems more likely the focus will be on the Cybercab and the huge accomplishment that will come with releasing a vehicle with no manual controls.

There Will Be a Lot of Hype

What’s important to remember about the Cybercab event is that Tesla will continue to prioritize safety and the rollout will likely be slow, just as it has been with Robotaxi.

One of the biggest complaints about Robotaxi is vehicle population, and the fact that the wait for a ride, at least in some instances, has been longer than most want to admit.

Tesla Cybercab fleet grows in Austin ahead of launch event

It will take time for this project to truly scale. It will take time for Tesla to roll this out in a large fashion. The important thing to note is that they are doing it, and they’re doing it with a vehicle that is completely engineered and built internally. That’s something no other ride-hailing service can say.

SpaceX would not exist if this crucial early launch failed, Musk says

Published

Elon Musk recently restated a fact that still defines SpaceX’s origin story: if Falcon 1’s fourth launch had failed, the company would not exist. The comment answered a reminder that after three consecutive losses, SpaceX had money for only one more attempt.

On X, Peter Diamandis said that the present-day acknowledgement of SpaceX’s success does not discount the rough start the company had. “Almost nobody remembers that Elon’s first rocket failed three times, and there was money for exactly only one more attempt.”

Musk said, “If the 4th launch had failed, SpaceX would not exist.”

In late 2008, the firm was nearly out of cash. Another failure would have ended payroll, closed the Hawthorne factory, and left the Falcon 9 and Dragon programs as unfinished drawings.

The first flight lifted off from Omelek Island on 24 March 2006. Thirty-three seconds later, a corroded aluminum fitting on a fuel line leaked. Kerosene ignited around the Merlin engine, control was lost, and the vehicle came apart. The small DARPA payload, FalconSAT-2, survived the short flight only to land on a storage shed near the pad. Investigators later traced the fitting to a materials mix-up that should never have reached the rocket.

Flight 2, on 21 March 2007, looked far better at first. The first stage burned cleanly and handed off to the Kestrel-powered upper stage. The vehicle crossed 100 kilometers and reached a peak of about 289 kilometers. Then propellant slosh in the second-stage tank started a circular coning motion that grew until the engine shut down. Telemetry faded as the stage tumbled, and SpaceX had reached space but not orbit. Over the next year, the team redesigned everything from the ground up, including tanks, baffles, and the new regeneratively cooled Merlin 1C.

That engine flew on Flight 3 on 2 August 2008. The first stage performed almost perfectly and reached 217 kilometers. After main-engine cutoff, leftover fuel in the cooling channels produced a faint residual thrust, roughly 10 pounds per square inch of chamber pressure. On a Texas test stand, the effect was invisible beneath ambient air pressure. In vacuum it was enough to push the spent first stage back into the second stage after separation. The stages collided, the upper stage spun, and the mission was lost. Musk later said a slightly longer delay before staging would have saved the flight.

Six weeks later, the team assembled Flight 4 from remaining parts and flew it on 28 September 2008 at 23:15 UTC. The payload was Ratsat, a 165-kilogram aluminum mass simulator built in-house. Staging was delayed so residual thrust could decay. The Kestrel ignited, the fairing split away, and nine and a half minutes after liftoff the vehicle was in orbit. After a coast, the second stage restarted, settling into a 621-by-643-kilometer path at 9.35 degrees inclination. Falcon 1 became the first privately developed liquid-fueled rocket to reach Earth orbit. Musk called the insertion “middle of the bull’s-eye.”

SpaceX restores a Falcon 1 rocket for 10th anniversary of first launch success

That success unlocked NASA’s Commercial Resupply Services award later that year. Without it, there would have been no Falcon 9, no reusable first stages, and no Dragon cargo or crew flights to the International Space Station. Launch prices would have remained far higher. Starlink’s constellation would not exist; broadband from low Earth orbit would still be a paper concept.

Ride-share markets, high launch cadence, and the current pace of lunar and Mars hardware would be years behind. Communications, Earth observation, and the cost of putting anything into space would look more like the 2000s than the 2020s.

One extra second of residual thrust in August 2008 would have written a different decade.
