NASA Again Calls New Mission to Fix Hubble! SpaceX Starship to Save…

Hubble remains one of humanity's greatest eyes on the universe. For decades it has endured the harsh conditions of space, transforming our understanding of the cosmos through extraordinary discoveries. But after years in orbit, even this legendary observatory is facing serious challenges, and keeping it operational may require help from Earth. NASA is now exploring ways to extend Hubble's mission without introducing complications like those seen with other observatories, including Swift. And one potential partner stands out, SpaceX. Could its growing capabilities and perhaps even Starship give Hubble a new lease on life? Let's find out on today's episode. Humanity is entering a new era of space exploration, and space telescopes have been among the pioneers leading the way. And just as these observatories continue pushing the boundaries of what we can discover, great SpaceX is working toward its own ambitious milestone. Reaching millions of subscribers. So if you haven't subscribed yet, now is your chance to become one of the founding members of our growing community. Thank you for being part of the journey. Now among all the space telescopes currently operating, one deserves special recognition, the Hubble Space Telescope. Launched aboard the space shuttle in 1990, Hubble has spent more than 36 years orbiting Earth, capturing extraordinary images and fundamentally transforming our understanding. But after decades of service, even this legendary observatory is beginning to show its age. Between the harsh environment of space and the gradual deterioration of its onboard systems, Hubble increasingly depends on support from Earth. And now that support may finally be on the way. According to a Request for Information, or RFI, published by NASA on October 29th, The agency is exploring the possibility of another in-space servicing mission for Hubble. The proposal outlines several major objectives. First, NASA wants to find a way to raise Hubble's orbit, which is gradually declining because of atmospheric drag. Second, the agency is interested in a servicing mission that could improve the telescope's performance, strengthen its resilience, and extend its operational lifetime. Finally, NASA is also examining the possibility of a controlled de-orbit mission when Hubble eventually reaches the end of its service life. The requirements outlined in the document include developing, testing, and operating a vehicle capable of capturing Hubble in low Earth orbit and raising it to an altitude of at least 600 kilometers. And if extending its life is no longer practical, the agency wants a controlled re-entry solution to safely dispose of the telescope. As for the timeline. NASA is looking toward that's roughly five to six years from now and the timing is important. Without intervention, Hubble's orbit could decay to the point of uncontrolled atmospheric re-entry around 2033 or 2034. NASA is currently inviting interested organizations to provide feedback with submissions due by November 30th. But who could actually take on such a demanding mission? Before we answer the question, we need to understand Why Hubble needs another rescue in the first place, and why this could become one of NASA's most important servicing decisions in years. In fact, this would be the sixth major servicing mission in Hubble's history. The telescope has already undergone five major repairs in 93, 97, 99, 2002, and 2009. All five were performed by space shuttle astronauts, and these missions involved some extraordinary engineering work. Astronauts installed corrective optics to compensate for Hubble's original mirror flaw, replaced scientific instruments and cameras, upgraded its power systems, and repaired or replaced critical components such as gyroscopes. Those servicing missions transformed what could have become a failed observatory into one of the most successful scientific missions in history. But the last major servicing mission took place in 2009, and 17 years is a very long time for a spacecraft operating in orbit. Since then. Hubble has continued experiencing problems involving its batteries, solar panels, onboard computers, fine guidance sensors, insulation, and scientific instruments such as STIS and ACS. Some components have failed outright, while others have gradually deteriorated. But two particular problems are especially relevant to NASA's latest proposal. The first is orbital decay. Unlike many spacecraft, Hubble does not have its own propulsion system for routinely maintaining its orbit. The second problem involves Hubble's gyroscopes. These devices are essential for determining the telescope's orientation and keeping it accurately pointed at distant targets. Originally, Hubble had six gyroscopes, and its standard operating configuration required at least three for stable pointing. Over the years, however, several of them have failed. The situation became particularly serious in 1999, when multiple gyroscope failures forced into safe mode and required an urgent servicing mission during Hubble the final space shuttle servicing mission in 2009. you Astronauts replaced all six gyroscopes, but even those replacements had a limited operational for lifetime. Three used an older design that was more vulnerable to corrosion in a thin electrical watching. connection known as a flex lead. Between 2018 and 2020, all three eventually failed. That left Hubble relying on the remaining three gyroscopes, which featured an improved and more durable design. Unfortunately, even these began experiencing problems. One of them, Gyroscope 3 started producing unreliable readings in 2018. This situation worsened toward the end of 2023 and became particularly disruptive in April and May of 2024. When repeated anomalies caused Hubble to enter safe mode and temporarily suspend scientific observations. By June of 2024, NASA had decided to transition Hubble to a single gyroscope operating mode. One gyroscope would remain active while another would be kept in reserve to extend the observatory's remaining operational life. This approach had actually been studied for decades, and it allowed Hubble to continue conducting valuable science. Despite having fewer functioning gyroscopes, however, there are trade-offs operating with a single gyroscope can reduce observing efficiency, increase the time needed to reposition the telescope and limit its ability to track certain fast moving objects. NASA has nevertheless indicated that Hubble would continue making important scientific contributions for years under this configuration. But the underlying problem remains. Its systems are aging, its orbit is declining, and the opportunity to perform another major repair is becoming increasingly limited. That's why this sixth servicing mission could be so important. And this time, NASA needs a partner it can trust. The recent attempt to service the Swift Observatory shows why. NASA awarded Catalyst Space Technologies a contract worth approximately $30 million U.S. dollars to develop Link. A spacecraft designed to raise SWIFT's orbit and extend its operational life. But during its rendezvous attempt, LINC encountered control difficulties, preventing the servicing operation from proceeding as planned. As a result, NASA was forced to end SWIFT's mission, and it had to re-enter and land in the waters off Sumatra, Indonesia. This example shows that a spacecraft must precisely match its target's movement, Establish a secure connection and apply thrust without damaging delicate instruments. And with Hubble, the stakes are even higher. NASA cannot afford a mistake that could permanently damage one of its most valuable scientific observatories. So which company could be the right fit for this mission? One potential partner stands out, SpaceX, particularly its Dragon spacecraft and the long-term capabilities of Starship. The idea of using SpaceX hardware to service Hubble dates back to 2022. When Jared Isaacman proposed a mission to extend the telescope's operational life, NASA ultimately declined, citing safety concerns. Now, with Isaacman serving as NASA Administrator, the proposal is back under consideration. On October 30th, he emphasized that Hubble's scientific value makes it worth exploring cost-effective ways to keep the observatory operational rather than replacing it entirely. He also warned that Hubble is approaching an orbital altitude where recovery may no longer be practical. So what could SpaceX actually offer? Let's start with Dragon. Crew Dragon and Cargo Dragon have extensive experience performing automated rendezvous and docking operations with the ISS. They've demonstrated the precision needed to approach large orbital structures, maintain position, ...and safely establish connections. Dragon has also demonstrated its ability to raise the orbit of a much larger spacecraft. During an ISS Reboost demonstration, its Draco thrusters helped increase the station's altitude. That experience could prove valuable for Hubble, especially because NASA already installed a soft-capture mechanism during the telescope's 2009 servicing mission. This docking interface was specifically designed to allow future spacecraft to attach to the observatory. But for a more ambitious servicing mission, NASA could have another option, Starship. Hubble weighs approximately 11 to 12 metric tons. Raising it from its current orbit of around 470 kilometers to above 600 kilometers would require an estimated velocity change of roughly 70 meters per second under certain mission assumptions. The maneuver itself may be relatively modest, but safely capturing and moving such a large observatory is another challenge. This is where Starship's size and payload capacity could become valuable. It could potentially transport specialized propulsion modules, robotic arms, replacement components, and equipment for more extensive repairs. Its proposed cargo volume could also accommodate larger servicing hardware than conventional spacecraft. And there is an even more ambitious possibility, bringing Hubble back to Earth intact. That would require a specially designed vehicle and capture system capable of securing the telescope for the return journey. Starship has demonstrated nothing like this, but its enormous dimensions could make such a concept worth exploring. A crewed servicing mission is another possibility, although that would require life support systems, crew accommodations, and extensive certification. Then, there is the economic argument. Starship is being developed around full reusability. If SpaceX eventually achieves reliable recovery, rapid turnaround, and a high launch cadence, the cost of transporting large servicing equipment into orbit could fall considerably. And with NASA looking toward 2032, SpaceX would have several more years to develop its capabilities including orbital operations, vehicle recovery, and in-space refueling. By then, Starship could be a far more capable platform than it is today. Of course, SpaceX isn't the only potential partner. Companies such as Astroscale and Northrop Grumman are also developing technologies for satellite servicing, inspection, and orbital operations. However, SpaceX has one distinct advantage. It operates its own launch vehicles, spacecraft, and supporting infrastructure. That vertical integration could simplify coordination and give NASA greater flexibility when planning such a complex mission. Complex mission. Still, Starship isn't automatically the answer. Any servicing vehicle must carefully control contamination. Exhaust, lubricants, and other materials could deposit unwanted substances on Hubble's sensitive optical surfaces. The spacecraft must also approach and capture the telescope without damaging its structure. But given SpaceX's experience with orbital transportation and the potential capabilities of Dragon and Starship, the company deserves serious consideration. And with that, thank you for tuning in to today's episode. I'm Kevin, and I'll see you in the next one. Until then, keep looking up.
