  • NASA, Boeing and Coast Guard representatives to testify about implosion of Titan submersible

    NASA, Boeing and Coast Guard representatives to testify about implosion of Titan submersible

    Representatives for NASA, Boeing Co. and the U.S. Coast Guard are slated to testify in front of investigators Thursday about the experimental submersible that imploded en route to the wreckage of the Titanic.

    OceanGate co-founder Stockton Rush was among the five people who died when the submersible imploded in June 2023. The design of the company’s Titan submersible has been the source of scrutiny since the disaster.

    The Coast Guard opened a public hearing earlier this month that is part of a high level investigation into the cause of the implosion. Some of the testimony has focused on the troubled nature of the company.

    Thursday’s testimony is scheduled to include Justin Jackson of NASA; Mark Negley of Boeing Co.; John Winters of Coast Guard Sector Puget Sound; and Lieutenant Commander Jonathan Duffett of the Coast Guard Office of Commercial Vessel Compliance.

    Earlier in the hearing, former OceanGate operations director David Lochridge said he frequently clashed with Rush and felt the company was committed only to making money. “The whole idea behind the company was to make money,” Lochridge testified. “There was very little in the way of science.”

    Lochridge and other previous witnesses painted a picture of a company that was impatient to get its unconventionally designed craft into the water. The accident set off a worldwide debate about the future of private undersea exploration.

    The hearing is expected to run through Friday and include more witnesses.

    The co-founder of the company told the Coast Guard panel Monday that he hoped a silver lining of the disaster is that it will inspire a renewed interest in exploration, including the deepest waters of the world’s oceans. Businessman Guillermo Sohnlein, who helped found OceanGate with Rush, ultimately left the company before the Titan disaster.

    “This can’t be the end of deep ocean exploration. This can’t be the end of deep-diving submersibles and I don’t believe that it will be,” Sohnlein said.

    Coast Guard officials noted at the start of the hearing that the submersible had not been independently reviewed, as is standard practice. That and Titan’s unusual design subjected it to scrutiny in the undersea exploration community.

    OceanGate, based in Washington state, suspended its operations after the implosion. The company has no full-time employees currently, but has been represented by an attorney during the hearing.

    During the submersible’s final dive on June 18, 2023, the crew lost contact after an exchange of texts about Titan’s depth and weight as it descended. The support ship Polar Prince then sent repeated messages asking if Titan could still see the ship on its onboard display.

    One of the last messages from Titan’s crew to Polar Prince before the submersible imploded stated, “all good here,” according to a visual re-creation presented earlier in the hearing.

    When the submersible was reported overdue, rescuers rushed ships, planes and other equipment to an area about 435 miles (700 kilometers) south of St. John’s, Newfoundland. Wreckage of the Titan was subsequently found on the ocean floor about 330 yards (300 meters) off the bow of the Titanic, Coast Guard officials said. No one on board survived.

    OceanGate said it has been fully cooperating with the Coast Guard and NTSB investigations since they began. Titan had been making voyages to the Titanic wreckage site going back to 2021.

  • Boeing will fly its empty capsule back to Earth soon. Two NASA astronauts will stay behind

    Boeing will fly its empty capsule back to Earth soon. Two NASA astronauts will stay behind

    CAPE CANAVERAL, Fla. — Boeing will attempt to return its problem-plagued capsule from the International Space Station later this week — with empty seats.

    NASA said Wednesday that everything is on track for the Starliner capsule to undock from the space station Friday evening. The fully automated capsule will aim for a touchdown in New Mexico’s White Sands Missile Range six hours later.

    NASA’s two stuck astronauts who flew up on Starliner will remain behind at the orbiting lab. They’ll ride home with SpaceX in February, eight months after launching on what should have been a weeklong test flight. Thruster trouble and helium leaks kept delaying their return until NASA decided that it was too risky for them to accompany Starliner back as originally planned.

    “It’s been a journey to get here and we’re excited to have Starliner return,” said NASA’s commercial crew program manager Steve Stich.

    NASA’s Butch Wilmore and Suni Williams will close the hatches between Starliner and the space station on Thursday. They are now considered full-time station crew members along with the seven others on board, helping with experiments and maintenance, and ramping up their exercise to keep their bones and muscles strong during their prolonged exposure to weightlessness.

    To make room for them on SpaceX’s next taxi flight, the Dragon capsule will launch with two astronauts instead of the usual four. Two were cut late last week from the six-month expedition, which is due to blast off in late September. Boeing has to free up the parking place for SpaceX’s arrival.

    Boeing encountered serious flaws with Starliner long before its June 5 liftoff on the long-delayed astronaut demo.

    Starliner’s first test flight went so poorly in 2019 — the capsule never reached the space station because of software errors — that the mission was repeated three years later. More problems surfaced, resulting in even more delays and more than $1 billion in repairs.

    The capsule had suffered multiple thruster failures and propulsion-system helium leaks by the time it pulled up at the space station after launch. Boeing conducted extensive thruster tests in space and on the ground, and contended the capsule could safely bring the astronauts back. But NASA disagreed, setting the complex ride swap in motion.

    Starliner will make a faster, simpler getaway than planned, using springs to push away from the space station and then short thruster firings to gradually increase the distance. The original plan called for an hour of dallying near the station, mostly for picture-taking; that was cut to 20 or so minutes to reduce the stress on the capsule’s thrusters and keep the station safe.

    Additional test firings of Starliner’s 28 thrusters are planned before the all-important descent from orbit. Engineers want to learn as much as they can since the thrusters won’t return to Earth; the section containing them will be ditched before the capsule reenters.

    The stuck astronauts — retired Navy captains — have lived on the space station before and settled in just fine, according to NASA officials. Even though their mission focus has changed, “they’re just as dedicated for the success of human spaceflight going forward,” flight director Anthony Vareha said.

    Their blue Boeing spacesuits will return with the capsule, along with some old station equipment.

    NASA hired Boeing and SpaceX a decade ago to ferry its astronauts to and from the space station after its shuttles retired. SpaceX accomplished the feat in 2020 and has since launched nine crews for NASA and four for private customers.
