  • International Space Station Trash May Have Hit This Florida House

    International Space Station Trash May Have Hit This Florida House

    [ad_1]

    A few weeks ago, something from the heavens came crashing through the roof of Alejandro Otero’s home, and NASA is on the case.

    In all likelihood, this nearly 2-pound object came from the International Space Station. Otero said it tore through the roof and both floors of his two-story house in Naples, Florida.

    Otero wasn’t home at the time, but his son was there. A Nest home security camera captured the sound of the crash at 2:34 pm local time (19:34 UTC) on March 8. That’s an important piece of information because it is a close match for the time—2:29 pm EST (19:29 UTC)—that US Space Command recorded the reentry of a piece of space debris from the space station. At that time, the object was on a path over the Gulf of Mexico, heading toward southwest Florida.

    This space junk consisted of depleted batteries from the ISS, attached to a cargo pallet that was originally supposed to come back to Earth in a controlled manner. But a series of delays meant this cargo pallet missed its ride back to Earth, so NASA jettisoned the batteries from the space station in 2021 to head for an unguided reentry.

    Otero’s likely encounter with space debris was first reported by WINK News, the CBS affiliate for southwest Florida. Since then, NASA has recovered the debris from the homeowner, according to Josh Finch, an agency spokesperson.

    Engineers at NASA’s Kennedy Space Center will analyze the object “as soon as possible to determine its origin,” Finch told Ars. “More information will be available once the analysis is complete.”

    Ars reported on this reentry when it happened on March 8, noting that most of the material from the batteries and the cargo carrier would have likely burned up as they plunged through the atmosphere. Temperatures would have reached several thousand degrees, vaporizing most of the material before it could reach the ground.

    The entire pallet, including the nine disused batteries from the space station’s power system, had a mass of more than 2.6 metric tons (5,800 pounds), according to NASA. Size-wise, it was about twice as tall as a standard kitchen refrigerator. It’s important to note that objects of this mass, or larger, regularly fall to Earth on guided trajectories, but they’re usually failed satellites or spent rocket stages left in orbit after completing their missions.

    In a post on X, Otero said he is waiting for communication from “the responsible agencies” to resolve the cost of damages to his home.

    If the object is owned by NASA, Otero or his insurance company could make a claim against the federal government under the Federal Tort Claims Act, according to Michelle Hanlon, executive director of the Center for Air and Space Law at the University of Mississippi.

    “It gets more interesting if this material is discovered to be not originally from the United States,” she told Ars. “If it is a human-made space object which was launched into space by another country, which caused damage on Earth, that country would be absolutely liable to the homeowner for the damage caused.”

    This could be an issue in this case. The batteries were owned by NASA, but they were attached to a pallet structure launched by Japan’s space agency.

    How This Happened

    At the time of the March 8 reentry, a NASA spokesperson at the Johnson Space Center in Houston said the space agency “conducted a thorough debris analysis assessment on the pallet and has determined it will harmlessly reenter the Earth’s atmosphere.” This was, by far, the most massive object ever tossed overboard from the International Space Station. “We do not expect any portion to have survived reentry,” NASA said.

    Research from other space experts, however, did not match NASA’s statement. The Aerospace Corporation, a federally funded research and development center, says a “general rule of thumb” is that 20 to 40 percent of the mass of a large object will reach the ground. The exact percentage depends on the design of the object, but these nickel-hydrogen batteries were made of metals with relatively high density.

  • The 4 Big Questions the Pentagon’s New UFO Report Fails to Answer

    The 4 Big Questions the Pentagon’s New UFO Report Fails to Answer

    [ad_1]

    But what, then, were those programs? Herein lies the most intriguing—and potentially ground-breaking—question that the Pentagon study leaves us wondering: What exactly are the secret compartmentalized programs that the whistleblowers and government witnesses misidentified as being related to UAP technology? What, exactly, are the Pentagon, intelligence community, or defense contractors working on that, from a concentric circle or two away inside the shadowy world of SAPs, looks and sounds like reverse-engineering out-of-this-world technology or even studying so-called “non-human biologics”?

    There are at least four clear possibilities.

    Secret Tech From Foreign Nations

    First, what exotic technological possibilities have been recovered from unknown terrestrial sources? For example, if the government is working on reverse-engineering technologies, those technologies are likely from advanced adversary nation-states like China, Russia, and Iran, and perhaps even quasi-allies like Israel that may be more limited in their technology-sharing with the US. What have other countries mastered that we haven’t?

    A Question of ‘Peculiar Characteristics’

    Second, what technologies has the US mastered that the public doesn’t know about? One of the common threads of UFO sightings across decades have been secret military aircraft and spacecraft in development or not yet publicly acknowledged. For example, the CIA estimated that the U-2 spy plane in the 1950s accounted for as much as half of reported UFO sightings. And the AARO report spends a half-dozen pages documenting how confusion over subsequent generations of secret US government aircraft appear to have also contributed to the great intergalactic game of telephone of UFO programs inside the government, including modern Predator, Reaper, and Global Hawk drones. AARO investigated one claim where a witness reported hearing a former US military service member had touched an extraterrestrial spacecraft, but when they tracked down the service member, he said that the conversation was likely a garbled version of the time he touched an F-117 Nighthawk stealth fighter at a secret facility.

    There are surely other secret craft still in testing and development now, including the B-21 stealth bomber, which had its first test flight in November and is now in testing at Edwards Air Force Base in California, as well as others we don’t know about. The government can still surprise us with unknown craft—like the until-then-unknown modified stealthy helicopter left behind on the Pakistan raid to kill Osama bin Laden. And some of these still-classified efforts are likely causing UFO confusion too: AARO untangled one witness’s claim of spotting a UAP with “peculiar characteristics” at a specific time and place and were able to determine, “at the time the interviewee said he observed the event, the DOD was conducting tests of a platform protected by a SAP. The seemingly strange characteristics reported by the interviewee match closely with the platform’s characteristics, which was being tested at a military facility in the time frame the interviewee was there.” So what was that craft—and what were its “peculiar characteristics?”

    Relatedly, the US military has a classified spaceship, the X-37B, that has regularly orbited around the Earth since its first mission in 2010—it just blasted off on its seventh and most recent mission in December—and its previous, sixth, mission lasted a record-breaking 908 days in orbit. The Pentagon has said remarkably little about what it does up there for years at a time. What secret space-related or aviation-related programs is the government running that outsiders confuse as alien spacecraft?

    A Material Matter

    The third likely area of tech development that might appear to outsiders to be UFO-related is more speculative basic research and development: What propulsion systems or material-science breakthroughs are defense contractors at work on right now that could transform our collective future? Again, AARO found such confusion taking place: After one witness reported hearing that “aliens” had observed one secret government test, AARO traced the allegation back to find “the conversation likely referenced a test and evaluation unit that had a nickname with ‘alien’ connotations at the specific installation mentioned. The nature of the test described by the interviewee closely matched the description of a specific materials test conveyed to AARO investigators.” So what materials were being tested there?

    There are some puzzling materials-science breadcrumbs wrapped throughout the AARO report. It found one instance where “a private sector organization claimed to have in its possession material from an extraterrestrial craft recovered from a crash at an unknown location from the 1940s or 1950s. The organization claimed that the material had the potential to act as a THz frequency waveguide, and therefore, could exhibit ‘anti-gravity’ and ‘mass reduction’ properties under the appropriate conditions.” Ultimately, though, the new report concluded, “AARO and a leading science laboratory concluded that the material is a metallic alloy, terrestrial in nature, and possibly of USAF [US Air Force] origin, based on its materials characterization.”

    A Knowledge Limit

    Fourth and lastly is the category of the truly weird: Scientists at the forefront of physics point out that we should be humble about how little of the universe we truly understand; as Harvard astronomy chair Avi Loeb explains, effectively all that we’ve learned about relativity and quantum physics has unfolded in the span of a single human lifespan, and astounding new discoveries continue to amaze scientists. Just last summer, scientists announced they’d detected for the first time gravitational waves criss-crossing the universe that rippled through space-time, and astrophysicists continue to suspect that the universe is far weirder than we think. (Italian astrophysicist Carlo Rovelli last year posited the existence of “white holes” that would be related to black holes, which, he pointed out, were still a mystery just 25 years ago when he was starting his career.)

    Answers here could be almost unfathomably weird—think parallel dimensions or the ability to travel at a fraction of the speed of light. And one of the most intriguing questions left by the UAP “game of telephone” is whether there are truly astounding advances in physics that government scientists, defense contractors, or research laboratories or centers could be feeling around that could also appear from the outside to be UFO-related.

  • Two lunar landers have fallen over – but they’re still doing okay

    Two lunar landers have fallen over – but they’re still doing okay

    [ad_1]

    An image taken by the Odysseus lander moments after it tipped over

    Intuitive Machines

    Both of the landers currently on the surface of the moon have ended up lying on their sides, but they still appear to be functioning surprisingly well.

    The Smart Lander for Investigating Moon (SLIM) launched by the Japan Aerospace Exploration Agency (JAXA) touched down on the moon on 19 January, marking a milestone for Japan as its first lunar lander. US company Intuitive Machines landed its Odysseus spacecraft – nicknamed Odie – on the lunar surface on 22 February, becoming the first private company to successfully put a spacecraft on the moon.

    Despite being on its side, Odysseus’s solar panels have been functioning since it landed. However, the antenna that is supposed to point towards Earth to transmit data isn’t oriented correctly, slowing the flow of information. Odysseus has been taking data and slowly sending images back to Earth, but its solar panels will soon be bathed in the frigid darkness of lunar night.

    “Once the sun sets on Odie, the batteries will attempt to keep the vehicle warm and alive, but eventually it’ll fall into a deep cold,” said mission director Tim Crain in a press conference on 23 February. “Of course, the next time the sun illuminates the solar arrays, we’ll turn our dishes to the moon, just to see if the radios and the batteries and the flight computers survive that deep cold.” Odysseus is expected to stop transmitting on 27 February, according to a post on X from Intuitive Machines.

    The two landers are both near the moon’s south pole, but they are far enough away from one another that their days begin and end at different times – as the sun goes down on Odysseus, it will still be midday where SLIM is settled.

    But because it was also tilted on its side when it landed, SLIM’s solar panels were not collecting any sunlight, so a few hours after its landing, its operators shut it down to preserve battery life. The hope was that if the solar panels did become illuminated as the sun moved across the sky, it could turn on again. This occurred nine days later, but only lasted for a few days before the lander was plunged into lunar night, with temperatures dropping as low as -133°C (-208°F) – far too cold for the spacecraft to continue to function.

    But it appears to have survived the deep freeze. On 25 February, the official SLIM account on X posted that a signal had been received from the lander. However, the post also stated: “As it was still midday on the moon, the temperature of the communication equipment was extremely high, so communication was terminated after only a short period of time.”

    As the day wanes over the SLIM lander, its operators will try once again to establish communication. If this works, it may lend some hope that the Odysseus lander could survive lunar night as well. With several other landing attempts this year failing, that hope is much needed. In all, there are 10 missions planned for the the south pole of the moon this year, and in two more years the Artemis III mission aims to return astronauts to the moon for the first time in more than 50 years.

  • NASA Investigates Renaming James Webb Space Telescope after Anti-LGBT+ Claims

    NASA Investigates Renaming James Webb Space Telescope after Anti-LGBT+ Claims

    [ad_1]

    NASA is considering whether to rename its flagship astronomical observatory, given reports alleging that James Webb, after whom it is named, was involved in persecuting gay and lesbian people during his career in government. Keeping his name on the US$8.8-billion James Webb Space Telescope (JWST)—set to launch later this year—would glorify bigotry and anti-LGBT+ sentiment, say some astronomers. But others say there is not yet enough evidence against Webb, who was head of NASA from 1961 to 1968, and they are withholding judgement until the agency has finished an internal investigation.

    The JWST, which will peer into the distant reaches of the cosmos, is NASA’s biggest astronomical project in decades, so the stakes are high. In May, citing Webb’s purported involvement in discrimination, four prominent astronomers launched a petition to change the telescope’s name. It has amassed 1,250 signatories, including scientists who have been awarded observing time on the telescope.

    NASA’s acting chief historian, Brian Odom, is working with a non-agency historian to review archival documents about Webb’s policies and actions, according to agency officials. Only after the investigation concludes will NASA decide what to do.

    “We must make a conscious decision,” Paul Hertz, head of NASA’s astrophysics division, told an agency advisory committee on 29 June. “We must be transparent with the community and with the public for the rationale for whichever decision we make.”

    Searching the archives

    Former NASA administrator Sean O’Keefe named the JWST after Webb in 2002, when the telescope was in the early stages of development. It was a unilateral decision that took many by surprise, because NASA’s telescopes are typically named after scientists. Webb, who died in 1992, was a bureaucrat who held several administrative roles in the US government.

    O’Keefe chose the name because Webb had advocated that NASA keep science as a key part of its portfolio in the 1960s, even as the Apollo programme of human space exploration soaked up most of the agency’s attention and budget. O’Keefe tells Nature he was not aware of the accusations when he picked the name, and he supports keeping it unless more information surfaces. “Without James Webb’s leadership, there may have been no telescope or much of anything else at NASA noteworthy of a naming controversy,” he says.

    As Webb was beginning his career with the US government in the late 1940s, gay and lesbian employees were being systematically rooted out and fired because of their sexual orientation—a campaign encouraged by several prominent members of Congress. The period is known as the lavender scare, echoing the anti-Communist ‘red scare’ with which it was often intertwined. During the lavender scare, gay people were cast, untruthfully, as perverts who might be desperate to keep their sexual orientation secret and thus be susceptible to revealing government secrets under blackmail. Its epicentre was the Department of State, which handles foreign policy.

    The four astronomers leading the renaming petition say that when Webb worked for the state department in the high-ranking position of undersecretary from 1949 to 1952, he passed a set of memos discussing what was described as “the problem of homosexuals and sex perverts” to a senator who was leading the persecution. They point to records found in the US National Archives by astronomer Adrian Lucy at Columbia University in New York City. “The records clearly show that Webb planned and participated in meetings during which he handed over homophobic material,” the petition leaders wrote earlier this year in an opinion piece in Scientific American.

    The four astronomers are Lucianne Walkowicz at the Adler Planetarium in Chicago, Illinois; Chanda Prescod-Weinstein at the University of New Hampshire in Durham; Brian Nord at the Fermi National Accelerator Laboratory in Batavia, Illinois; and Sarah Tuttle at the University of Washington in Seattle. “We felt that we should take a public stand on naming such an important facility after someone whose values were so questionable,” they write in an e-mail to Nature. “It’s time for NASA to stand up and be on the right side of history.”

    David Johnson, a historian at the University of South Florida in Tampa who wrote the 2004 book The Lavender Scare, says he knows of no evidence that Webb led or instigated persecution. Webb did attend a White House meeting on the threat allegedly posed by gay people, but the context of the meeting was to contain the hysteria that members of Congress were stirring up. “I don’t see him as having any sort of leadership role in the lavender scare,” says Johnson.

    Walkowicz and their colleagues note that as a leader, Webb bore responsibility for discriminatory policies enacted at his agency. They also note the case of Clifford Norton, who was fired from his job at NASA because he was suspected to be gay in 1963, when Webb was NASA administrator. “We believe the known historical record speaks clearly in favour of renaming the telescope,” they say.

    NASA has given no estimate of when its investigation might be complete. Odom says that the COVID-19 pandemic has limited historians’ access to archival records.

    A reflection of values

    The push to rename the telescope falls into the broader reckoning over naming buildings, facilities and other objects after questionable historical figures. Last year, an aerospace executive began an as-yet unsuccessful effort to rename a NASA centre in Mississippi that is named after John Stennis, a senator who voted repeatedly in favour of racial segregation in the 1960s. In the past year or so, NASA has tried to address past discrimination against Black scientists and against women by naming its Washington DC headquarters after Mary Jackson, the first Black female engineer at the agency, and announcing that the flagship space telescope after the JWST will be named after Nancy Grace Roman, NASA’s first chief astronomer.

    The JWST debate comes near the end of a long and exhausting push to launch the observatory into space. Originally conceived in 1989 as the successor to the iconic Hubble Space Telescope, the craft is many years and billions of dollars over budget.

    To some, the telescope’s potential to transform astronomy makes it even more important that the JWST carry a name that reflects modern values. “For me, it really comes down to what kind of message we want to send to the more junior folks and students in our field,” says Peter Gao, a planetary scientist at the University of California, Santa Cruz. “The people we choose to celebrate by naming our telescopes after them is a reflection of our values.”

    The final decision lies with NASA administrator Bill Nelson, who has not said anything publicly on the matter. There is no clear list of alternative names, although many people have made unofficial suggestions. Walkowicz and the other astronomers who are leading the petition suggest Harriet Tubman, after the formerly enslaved woman who fought to end slavery in the United States in the nineteenth century and used the stars to guide Black people to freedom. Saurabh Jha, an astronomer at Rutgers University in New Brunswick, New Jersey, suggests Cecilia Payne-Gaposchkin, whose work revolutionized astronomers’ understanding of the composition of the Universe in the early twentieth century.

    Some astronomers who plan to use the JWST are already thinking about what they will do if the telescope is not renamed. One idea is to acknowledge LGBT+ rights in the acknowledgements sections of papers published using JWST data, says Johanna Teske, an astronomer at the Carnegie Institution for Science in Washington DC.

    Many are keen to see what the NASA investigation might unearth. “It’s important to look at what happened and what the facts are,” says Rolf Danner, an astronomer at NASA’s Jet Propulsion Laboratory in Pasadena, California, who is chair of the American Astronomical Society’s committee on sexual orientation and gender minorities in astronomy. “And then really ask ourselves—would we make that choice again?”
