Virgin Galactic reaches space in rocket-powered plane, eyes space tourism in 2019

Published

on

Virgin Galactic, the space tourism company founded by entrepreneur Richard Branson, has successfully made it to space for the first time with VSS Unity, their SpaceShipTwo-class rocket-powered plane, during the craft’s 4th test flight. This accomplishment makes Virgin the first US-based venture to carry humans to the edge of space since the Space Shuttle program ended in 2011, edging out others with similar goals such as SpaceX and Blue Origin. After taking off at 7:11 am this morning and detaching from WhiteKnightTwo, its custom airliner mothership, pilots Mark “Forger” Stucky and Rick “CJ” Sturckow reached a height 51.4 miles high in the craft to the edge of the stratosphere where they experienced weightlessness and the curvature of the Earth. This success brings the company one step closer to civilian tourist trips, something Branson hopes to achieve as early as 2019.

Unlike a traditional rocket which takes off from the ground, VSS Unity is flown to 43,000 feet underneath a specially designed airliner before being dropped and subsequently lighting up its rocket engines to power it vertically to an even higher altitude. After a 60-second engine burn speeds the craft to nearly three times the speed of sound, it continues its ascent, coasting until it reaches maximum altitude. A special “feather” system is then used for reentry, wherein the craft folds its wings and behaves like a traditional space capsule until the air thickens again, at which time the wings unfold again and behave like a space plane, gliding back to Earth and landing on a landing strip.

Becoming a passenger on one of VSS Unity’s future flights doesn’t come cheap, the price tag being $250,000 per 90-minute flight. However, given the 700 or so paid reservations, including several celebrities, it’s not the money that’s the challenge, it’s the technology. On October 31, 2014, Virgin suffered a crippling setback with the death of co-pilot Mike Alsubry and injury of pilot Peter Siebold when a predecessor craft crashed due to a combination of human error and an engineering flaw. The company received an abundance of criticism focused on whether the danger of space tourism made the rewards worthwhile, but after following recommendations set forth by the National Transportation Safety Board’s report on the incident along with further design and safety enhancements, they forged ahead to make today’s event a reality. Branson started Virgin Galactic in 2004.

At 51.4 miles high, VSS Unity reached the technical definition of space, earning its pilots commercial astronaut wings by the US Federal Aviation Administration, although the usual international standard is the 62-mile “Karman line”. A typical NASA “sounding rocket”, a small rocket generally launched with equipment on board to take measurements and scientific experiments during an approximately 30-minute sub-orbital flight only, reaches anywhere from 30-80 miles above the Earth. That said, the lower altitude of VSS Unity also provides an opportunity for research, serving the dual-purpose of science and recreation. Four research payloads from NASA’s Flight Opportunities Program were on board its historic test flight as well as a test dummy, making the trip revenue-earning for the first time as well.

Virgin Galactic has more tests of VSS Unity planned before moving to Spaceport America in New Mexico where it will set up its tourism operation. Branson hopes to compete directly with Blue Origin, the rocket company founded by Amazon’s Jeff Bezos which also plans to ferry customers to space. Bezos’s venture will use a more traditional, reusable ground-based rocket, the New Shepard, that lands after returning from sub-orbit similar to SpaceX’s Falcon 9 first stages. Unlike Virgin, crewed flights and “pre-sales” have not yet been part of Blue Origin’s process, but plenty of information is available for potential customers on its website.

The parent company of Virgin Galactic (Virgin) has another space-based venture in its wings: Virgin Orbit. Using a system similar to NASA’s Pegasus rocket, a small rocket complete with payload will launch from a modified Boeing 747-400 airliner, the combo being called LauncherOne and Cosmic Girl, respectively. The company has its sights set on the small satellite industry, identifying a need that’s not currently being met by other launch providers, and its business model centers on proving low-cost access to space for existing companies, students, entrereneurs, and other types hoping to use space as part of their research or business endeavors.

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

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.
