Watch: SpaceX flies, crashes Starship moon rocket again

Watch: SpaceX flies, crashes Starship moon rocket again

Science
Feb. 2 (UPI) -- SpaceX's test flight of the company's deep-space Starship rocket ended for a second time in a fiery explosion on the landing pad Tuesday in Boca Chica, Texas, after the Federal Aviation Administration modified the company's license to allow the launch. The rocket, named SN9, ascended to a height of more than 6 miles and performed a flip manuever. But after it descended, its engines appeared to ignite improperly, according to live video SpaceX provided. Advertisement The explosion is not necessarily a setback because the company is gathering data about the craft as it tests, said John Insprucker, the principal engineer at SpaceX, during the broadcast. SpaceX is known for losing rockets during early testing as it explores new designs. "We've done a lot of good things. We jus...
Report: U.S. reconnaissance aircraft flies over Korean Peninsula

Report: U.S. reconnaissance aircraft flies over Korean Peninsula

World
Dec. 16 (UPI) -- A U.S. spy plane designed to detect missile launches flew over South Korean airspace Wednesday, ahead of North Korea's planned Eighth Party Congress in January. The RC-135W, or Rivet Joint, flew over South Korea's West Sea, or the Yellow Sea, between China and Korean Peninsula, South Korean military intelligence sources told local newspaper Chosun Ilbo. Advertisement The reconnaissance aircraft, designed to gather telemetry and other electronic intelligence data before rocket launches, has previously appeared unannounced on the Korean Peninsula in 2020. On Wednesday, the plane left the Seoul metropolitan area about 1:30 p.m. local time and flew west. Its capabilities would have allowed it to conduct reconnaissance activity near Chinese and North Korean territory, the repo...
Disabled flies sleep more as they learn to adapt

Disabled flies sleep more as they learn to adapt

Science
May 8 (UPI) -- Some people need to psyche themselves up to meet challenges head on. For flies, tough times call for a little shuteye. New research suggests flies that are unable to fly sleep more as they learn to adapt to their disability. The research -- published Friday in the journal Science Advances -- could offer insights into the evolutionary origins of sleep, as well as the role sleep plays in human health and development. The sleep patterns of fruit flies are quite similar to those of humans. Young flies sleep more than older flies, with the need for sleep diminishing as a fly ages. Flies that are kept up all night catch up on sleep the next day. Caffeine keeps flies up, while antihistamines make them drowsy. In humans, sleep is important for learning and neural development, and...
When something smells foul, vinegar flies can't perceive pleasant odors

When something smells foul, vinegar flies can't perceive pleasant odors

Science
March 15 (UPI) -- Vinegar flies can't process pleasant odors when something smells bad. When faced with conflicting odors, the repellent odor supersedes, according to a new study. Previous studies showed the brain of the vinegar fly features separate neural circuits for good and bad smells. The studies also showed multiple pleasant odors can be perceived simultaneously by vinegar flies. When scientists layered good smells, the flies altered their behavior. For the latest study, published this week in the journal Nature Communications, researchers exposed vinegar flies to conflicting smells. Functional imaging technologies allowed the scientists to observe the brains of vinegar flies as they were exposed to both good odors and smells that repel. The experiments showed the repellent odor b...
