SD doctors on measles, removal of CDC vaccine experts
SIOUX FALLS, S.D. (KELO) – The South Dakota State Medical Association is speaking out against the recent removal of the entire advisory committee for vaccinations at the Center for Disease Control. This comes at the same time measles cases are being seen in South Dakota. This week, all 17 immunization experts who advise the Center for Disease Control and Prevention (CDC) were removed from their positions. South Dakota State Medical Association president, Dr. Keith Hansen, says he wasn't sure why when he heard the news. Pride fests and protests make for busy Sioux Falls weekend 'To me, it didn't make a lot of sense. Why would you fire all of these very well-respected, intelligent individuals who spend all this time and effort to come up with these recommendations?' Hansen said. In response to the change, Health and Human Services Secretary Robert F. Kennedy Jr. says he's already tapped their replacements. 'We're going to bring people on to the ACIP Panel, not anti-vaxxers, we're bringing people on who are credentialed scientists or highly credentialed physicians who are going to do evidence-based medicine,' RFK Jr. said. This month South Dakota saw it's second case of measles this year, both on the west side of the state. It's something Hansen says can be preventable by vaccines. 'Measles is a very highly contagious disease. So our best battle is for individuals to get the vaccine and to try to get as many people vaccinated as we can.' Hansen said. 'So that we maximize herd immunity and also the individual's immunity, and especially for our real young kids.'Monument Health's chief of staff, Dr. Michael Huot in Rapid City says the MMR vaccine is still used today since approved by the FDA in 1971. 'The reason we still use treatments that are that old is because they're extremely effective and extremely safe. So, of vaccinations that MMR has had hundreds of millions of people vaccinated,' Huot said. With over 100,000 followers on TikTok, Huot hopes to continue spreading medical knowledge to those in his community and beyond. 'It also kind of dispels a lot of misinformation out there. I think it's a way for people to connect with somebody locally,' Huot said. As of Wednesday, eight new vaccine members have been appointed to the panel by RFK Jr. Click here for more info about measles symptoms. Copyright 2025 Nexstar Media, Inc. All rights reserved.

SpaceX's Ninth Starship Test Flight Delivers Mixed Results
In its ninth test flight, SpaceX's launch vehicle Starship once again reached space, surpassing problems that prematurely ended its two previous test launches. But as with those ill-fated preceding flights, in this one, Starship still failed to reach the ground intact. Instead the vehicle spun out of control and disintegrated during atmospheric reentry. Although each Starship test thus far has succeeded in demonstrating powerful new technical advances that are crucial for the program's further progress, this marks the third flight in a row in which the titanic vehicle suffered a 'rapid unscheduled disassembly' that sent fiery debris cascading down to Earth. All that effort, it's hoped, will prove worthwhile if or when Starship enters regular operations because SpaceX aims to make the vehicle, by far, the largest and most capable fully reusable spacecraft ever flown. In the latest test, around 50 minutes after launch, SpaceX confirmed that Starship met its demise. At first, everything in the vehicle's flight appeared to be going well. Starship—a 40-story-tall 'stack' that is composed of a giant, 33-engine Super Heavy booster and a 171-foot-long spacecraft powered by six additional engines—lifted off as planned from SpaceX's launch site in Starbase, Tex., at 7:37 P.M. EDT on Tuesday. But cheers were somewhat subdued until about 10 minutes after launch—when operators officially determined that the spacecraft's trajectory was nominal, taking it on a ballistic suborbital path through outer space. [Sign up for Today in Science, a free daily newsletter] 'Ship engine cutoff—three most beautiful words in the English language,' declared Dan Huot, a communications manager at SpaceX, during the company's livestream of the flight test near the launch site. Around him, sighs of relief could be heard as SpaceX employees began to ascertain that the day's flight would not be a repeat of the previous two, each of which had resulted in the vehicle exploding over the Atlantic Ocean less than 10 minutes after launch. Around 18 minutes after Tuesday's launch, however, issues began to emerge. First, operators decided not to deploy Starlink satellite demonstrations as planned because of a stuck payload door. Then, about a half an hour after launch, SpaceX mission control reported that suspected propellant leaks were driving the vehicle into a spin, which doomed it to burn up in the atmosphere during reentry—raining debris over the Indian Ocean. 'We're not going to get all of that reentry data that we're still really looking forward to,' Huot admitted in the livestream. 'This is a new generation of ship that ... we're really trying to put through the wringer, as there's a whole lot we still need to learn.' Meanwhile, although the Starship vehicle itself showed improved performance, the Super Heavy booster that helped it reach space ran into problems of its own. Moments after firing its engines to come in for a landing in the Atlantic Ocean, the booster instead broke apart. This wasn't entirely unexpected; in keeping with SpaceX's 'test to failure' approach, the Super Heavy had attempted to reenter in a different, potentially fuel-saving orientation that subjected the booster to more intense aerodynamic forces. Despite its unplanned disassembly, the booster did mark a significant milestone for SpaceX: for the first time, it flew with a nearly full suite of flight-proven engines that were previously used during Starship's seventh test. And the booster remains a marvelous demonstration of SpaceX's innovation; a Super Heavy previously made spaceflight history when it became the first rocket ever to be caught in midair with two mechanical arms. In the new launch, the Super Heavy was able to do its intended jobs of bringing Starship to space and testing new reentry techniques, explained Jessie Anderson, SpaceX's senior manufacturing engineering manager, during the flight's livestream. 'There's always a chance we don't reach every objective that we set for ourselves,' Anderson added, 'but success comes from what we learn on days like today.' On X, former NASA deputy administrator Lori Garver praised SpaceX's transparency but noted these were 'not the results we were hoping for.' Garver was instrumental in forging the space agency's partnership with SpaceX, which helped spark the company's unprecedented dominance of commercial launch services upon which NASA now heavily relies. Starship is the prized cornerstone of SpaceX's ambitious plan to build human settlements on Mars and is also slated to ferry crews to the lunar surface in a couple of years for NASA's Artemis III mission. Given the high stakes for the vehicle, its test program's mixed results are disappointing, to say the least. Notably, the previous two attempts, Flights 7 and 8, each ended with two spectacular explosions over the Atlantic Ocean. For Flight 8 in particular, the engines shut down unexpectedly minutes after launch, causing the spacecraft to essentially fall apart and self-destruct in midair. SpaceX received some public backlash after the spacecraft debris, which the company claimed would pose minimal risks, led to multiple midflight diversions for passenger airplanes that were under threat. Nevertheless, SpaceX appeared stalwart and even optimistic about Flights 7 and 8, calling the latter's mishap an 'energetic event' that occurred because of hardware complications. Last week the company said both explosions had a 'distinctly different' cause. And in a press release that followed the launch of Flight 9, it noted that Flight 8 greatly informed the upgrades and modifications to Starship for the latest test. 'Developmental testing by definition is unpredictable,' SpaceX said in a prelaunch press release for Flight 9. 'But by putting hardware in a flight environment as frequently as possible, we're able to quickly learn and execute design changes as we seek to bring Starship online as a fully and rapidly reusable vehicle.' What does Starship's questionable status mean for SpaceX's long-touted goal of 'making life multiplanetary'? If anything, it suggests the company's projections for the vehicle's regular, routine operation have been and remain unrealistically optimistic. Last year SpaceX founder Elon Musk stated in a social media post that the company plans to launch 'about five' uncrewed Starships to Mars in two years. In another post shortly after Flight 9's mixed results, he touted the vehicle's partial success and predicted that the next few flights would occur at a fast pace of about one per month. Whether or not such haste is feasible, it would certainly be desirable, given the pressure SpaceX faces to deliver on its lofty promises.

On Ninth Test Flight, SpaceX's Starship Rocket Survives Launch But Not Space
PCMag editors select and review products independently. If you buy through affiliate links, we may earn commissions, which help support our testing. SpaceX launched its Starship rocket for the ninth time tonight, and for the first time since the sixth flight in November, that enormous launch vehicle's second stage reached space intact. But then things went awry as the upper stage spun out of control and burned up on atmospheric re-entry. This was not the sequel SpaceX had hoped to stage to the previous two test flights in January and March. Both ended early when Starship's second stage exploded during its climb to space, leaving trails of glowing debris re-entering the atmosphere over the Caribbean and forcing the diversion or delay of dozens of airline flights. Tuesday's flight lifted off at 6:36 p.m. Central time from SpaceX's Starbase facility at Boca Chica, Texas, following two brief holds to troubleshoot ground equipment. The 33 methane-fueled Raptor engines in the 403-foot-tall rocket's booster—the same first stage used in January's launch—sent it arcing out over the Gulf of Mexico and up to Starship's "hotstage" cutover, where the second stage's engines ignite while still attached to the first stage. The company did not attempt to catch the booster with the 'chopsticks' arms of its launch tower so it could test a landing burn with an engine out. The booster did not survive that test, instead exploding before it could finish that burn and softly land in the water. Starship's second stage appeared to be doing much better, with its six Raptors putting it into the planned suborbital trajectory. 'Ship engine cutoff, the three most beautiful words in the English language,' SpaceX launch commentator Dan Huot exhaled on the company's livestream. But things went sideways from then on, figuratively and literally. SpaceX could not complete the next test planned in this mission, deploying simulated Starlink satellites, after the payload bay door failed to open properly. Huot reached for the obligatory space-sci-fi reference: 'HAL told me no, said I'm sorry Dan, I can't do that.' SpaceX's plans for its broadband satellite constellation include being able to launch at least 50 upgraded Starlinks in one Starship flight. In 2023, Elon Musk suggested the first such launch could happen in 2024; Tuesday's flight was supposed to advance that aimed-for upgrade a little closer to reality. After a break in video coverage while Starship was in darkness above the Earth, the stream then revealed that Starship's upper stage had begun whirling out of control. 'We did spring a leak in some of the fuel tank systems inside of Starship,' Huot reported. 'At this point, we've essentially lost our attitude control with Starship.' That put an end to the rest of the testing planned for the mission and ensured a fiery doom for Starship. Increasingly intermittent video, relayed via Starlink, showed the vehicle wreathed in brightly colored plasma, with one of its control fins disintegrating from that heat; telemetry stopped with whatever was left of Starship about 37 miles above the Indian Ocean. Musk put an optimistic spin on the flight in a post on X Tuesday evening: 'Starship made it to the scheduled ship engine cutoff, so big improvement over last flight!' The CEO also confirmed Huot's report of a tank leak. 'Leaks caused loss of main tank pressure during the coast and re-entry phase,' Musk continued. 'Lot of good data to review.' This footage could not have been comfortable viewing at NASA, because the space agency is also counting on the rocket. In 2021, NASA inked a $2.89 billion contract with SpaceX in 2021 to develop a version of Starship's upper stage as a crewed lunar lander for its Artemis return to the Moon. Two years later, the space agency awarded a $3.4 billion contract to Blue Origin in 2023 to develop a second lunar lander to fly on that firm's New Glenn rocket. President Trump's nominee to head NASA, billionaire payments executive and private astronaut Jared Isaacman, reposted a screengrab of one of Starship's final moments. 'Pretty incredible to get this kind of footage from the extreme environment of reentry. Appreciate the transparency—and bringing us space enthusiasts along through the highs and lows of a test program,' he tweeted. Isaacman, who has flown to space twice aboard SpaceX's Crew Dragon in missions he bankrolled himself, voiced confidence in the future of America's private space industry, which now extends well beyond SpaceX. 'Some may focus on the lows, but behind the efforts of Starship—and other programs like New Glenn, Neutron, Vulcan, Terran, Stoke, etc—is a massive space economy taking shape: tens of thousands of jobs, billions in private investment, all aimed at truly opening the last great frontier,' he wrote. 'When these capabilities arrive, they will spearhead a new era of exploration and discovery—and the lows will become a chapter in a much longer story.'

Watch: SpaceX's Starship spirals uncontrollably as fuel leaks in dramatic footage
SpaceX's 9th test flight fails SpaceX's Starship's ninth test flight started smoothly, leading many to believe it might be successful, but then the real trouble began. After the last two test flights ended prematurely with the destruction of the aircraft, Tuesday's Starship successfully reached orbit. However, the spacecraft failed to fully open its payload bay door, blocking the planned release of simulated Starlink satellites. Around 30 minutes into the mission, SpaceX confirmed a fuel tank leak aboard the vehicle. — AFP (@AFP) In the footage, the first-stage Super Heavy booster exploded shortly before its expected splashdown, and fuel leaks on the upper-stage vehicle caused it to spin uncontrollably before its planned re-entry through Earth's atmosphere. The company posted a statement on X reading, "As if the flight test was not exciting enough, Starship experienced a rapid unscheduled disassembly. Teams will continue to review data and work toward our next flight test. With a test like this, success comes from what we learn, and today's test will help us improve Starship's reliability as SpaceX seeks to make life multiplanetary.' 'We've been dealing with some leaks on the Ship,' SpaceX communications manager Dan Huot said on the livestream. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Dermatologista recomenda: simples truque elimina o fungo facilmente Acabe com os Fungo Undo 'This is also what led to that loss of attitude control. So at this point, we are kind of in a spin.' Due to the issue, mission controllers scrapped a planned demonstration to reignite one of Starship's Raptor engines while in orbit. Despite the complications, Starship is still on course to re-enter Earth's atmosphere and splash down in the Indian Ocean. However, the uncontrolled spin raises serious concerns about its heat shield surviving the descent. 'As we are not able to control the attitude of the ship as we get into entry, it will enter in whatever orientation it is in at the time, which does not bode well for the ship's heat shield,' Huot said. 'So it is definitely coming down. It is definitely heading to the Indian Ocean, but our chances of making it all the way down are pretty slim.'
