SpaceX wants to boost Hubble Space Telescope’s orbit with Dragon spacecraft

Published

on

NASA and SpaceX have signed a Space Act Agreement to study the feasibility of boosting the orbit of the iconic Hubble Space Telescope, potentially ensuring that the highly successful observatory will remain operable well into the middle of this century.

Thanks to three servicing missions completed in the 1990s and 2000s, Hubble remains highly productive more than 32 years after its launch. NASA believes that that will remain the case until at least the late 2020s or 2030s. However, many components of the telescope have spent decades in the unforgiving environment of space, raising unsurprising concerns about their longevity.

More importantly, the inexorable march of time, gravity, and Earth’s atmosphere mean that Hubble is guaranteed to eventually reenter that atmosphere and burn up without intervention. That demise could come as early as the mid-2030s, but SpaceX thinks it could help extend the telescope’s viability into the 2050s.

NASA and SpaceX will spend the next six or so months discussing whether it’s possible to use Dragon to boost the telescope’s orbit back to a nominal 600 kilometers (~372 mi). Both parties say that the agreement will also investigate the possibility of Dragon servicing missions, which could be even more significant for Hubble. While a boost that large would likely keep it in orbit for decades to come, there’s no guarantee the telescope would remain functional to take full advantage of the extra time it would have.

During the fifth and final Space Shuttle servicing mission, NASA astronauts installed a docking adapter (Soft Capture Mechanism) on the Hubble Telescope. Although no concrete plans existed for any additional servicing missions, the forward-facing installation of that adapter has made this feasibility study possible.

In theory, that docking adapter could make boosting Hubble’s orbit far more feasible, safe, and affordable than a Shuttle-style crewed servicing mission. SpaceX’s Cargo Dragon 2 spacecraft has the same autonomous docking capabilities its crewed sibling has and costs less to launch and operate, so it’s not inconceivable that an uncrewed Dragon could autonomously dock with Hubble and boost its orbit. Jessica Jensen, SpaceX’s Vice President of Customer Operations and Integration, says that an uncrewed option will be studied alongside crewed servicing and orbit-boost alternatives.

According to Patrick Crouse, NASA’s Hubble Space Telescope project manager, without a reboost, NASA would need to consider a separate mission to ensure a controlled deorbit of the massive telescope by “the end of the decade.” The study’s targeted boost of “40 to 70 kilometers,” meanwhile, could extend the longevity of Hubble’s orbit by “15 to 20 years,” or well into the 2050s. But as a feasibility study, there’s a chance that it will conclude that using Dragon – crewed or uncrewed – to boost or service HST isn’t feasible. Ordinarily, the most likely outcome would be a conclusion that the project is feasible from a technical perspective but out of reach from a financial perspective.

Enter billionaire and private astronaut Jared Isaacman, who was directly involved in the September 29th press conference. In September 2021, Isaacman – alongside four others – became the first all-private astronaut mission in history to reach orbit. After the spectacular success of Inspiration4, Isaacman’s relationship with SpaceX has become even closer. In early 2022, the pair announced a new endeavor – the Polaris Program – that intends to conduct at least two or three more private astronaut launches over the next few years.

Expanding the scope of their joint ambitions, the Polaris Program intends to debut the world’s first privately developed EVA spacesuit, test spacecraft-to-spacecraft communications using Starlink’s network of space lasers, and culminate in the first crewed launch of SpaceX’s next-generation Starship rocket. On its own, the decision to privately fund and develop an EVA suit and pursue the ability to conduct EVAs out of Crew Dragon represents a major leap forward for SpaceX and private spaceflight if realized.

But crucially, when asked about the synergies between the Polaris Program, SpaceX, and NASA, Isaacman revealed that he and SpaceX are willing to undertake a sixth Hubble servicing mission more or less pro bono, “with little or no potential cost to the government.” According to Isaacman, it’s possible that “the study could result in [a Hubble servicing mission] becoming the second [Polaris Program] mission.”

Polaris Dawn, the program’s first mission, was recently delayed from a late-2022 launch target to March 2023. The four private astronauts assigned to the mission (including Isaacman himself) recently began training for the historic private EVA, which will see two of four astronauts attempt to briefly exit their Crew Dragon spacecraft in new SpaceX-designed suits. With a targeted apogee of 1400 kilometers (~870 mi), the mission will also attempt to break the record for the highest Earth orbit reached by astronauts, and the spacewalk attempt will also occur at a record-breaking altitude of 700 kilometers (~435 mi)

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.

Tesla surges Robotaxi fleet ahead of Cybercab launch event

Tesla’s unsupervised robotaxi fleet quietly grew sevenfold in three weeks just before Cybercab Day arrives.

Published

Tesla’s unsupervised Robotaxi fleet has grown far faster than the public numbers suggested, and the timing lines up with the company’s biggest autonomy showcase yet. According to data compiled by the crowdsourced Robotaxi Tracker, Tesla now has nearly 200 vehicles operating without a safety monitor across Austin, Dallas and Houston, yielding a roughly 7X increase in about three weeks.

The jump lands four days before this week’s Tesla Cybercab launch event in Austin, where the company plans to show off its purpose-built, two-seat robotaxi with no steering wheel or pedals in a live commercial setting for the first time. Stick with us on X and Facebook for live reporting from the event.

The strategic logic is straightforward. Tesla has spent the past year scaling Robotaxi in small, deliberate steps, first widening geofences, then extending operating hours, then quietly growing fleet size, usually with little advance notice. Ashok Elluswamy told investors on the Q2 earnings call that the program had logged more than 380,000 unsupervised miles with zero notable incidents, a safety record the company has leaned on to justify moving slowly. Critics have used the flip side of that caution, a fleet that appeared stuck around two dozen vehicles for months, as evidence that Tesla’s driverless ambitions were outrunning its actual deployment.

A fleet quietly scaling to nearly 200 vehicles right before Cybercab Day undercuts that argument without Tesla having to say anything about it directly. It also sets up the event to do double duty. Rather than simply introducing new hardware, Tesla can point to an operating base of unsupervised Model Ys already running at meaningful scale, then argue the Cybercab, which uses the same underlying Full Self-Driving stack according to earlier coverage of the fleet’s software upgrades, is a natural next steps. Tesla has separately been registering the two-seat Cybercabs with Texas regulators this week, with the count climbing from seven to 45 in a matter of days.

The two ramps, one in software-driven Model Y deployment and one in physical Cybercab registrations, are happening in parallel rather than in sequence. That suggests Tesla wants Thursday’s event to land as proof that the robotaxi business is already running at scale, not just a reveal of a new vehicle shape. Whether the unsupervised numbers hold up once Cybercabs start mixing into the same fleet is the detail worth watching once the event wraps.
