NASA is racing to save its Swift telescope from falling back to Earth with a daring rescue mission. The salvage effort gets underway as soon as this week with the planned launch of a robotic lifesaver. NASA has hired Katalyst Space Technologies to boost Swift to a higher orbit where it can continue hunting for some of the universe's biggest explosions. Launched in 2004, Swift has been sinking faster and faster because of recent intense solar activity. It needs to get to a higher orbit as soon as possible to survive. Otherwise, it will come crashing down.

Mexico, Kenya, Italy and other nations are experiencing anywhere from one to two more months of heat stress than they were several decades ago, new research published Monday says, and some areas even more so. Regions previously untouched by heat stress are now feeling it, too. Extreme feels-like temperatures, heat stress days and tropical nights have all become dramatically more frequent, long and severe over the past six decades as the planet’s warming intensifies — a result of the burning of fossil fuels coal, oil and gas, according to a new study published in the journal Nature Climate Change on Monday.

Steven Spielberg's new film “Disclosure Day” explores extraterrestrial life and its impact on religion. UFOs, now also called UAPs, are gaining mainstream attention. The Pentagon released UFO files in May, sparking public curiosity. Former President Barack Obama set off a media frenzy by suggesting aliens exist in an interview. Some believe extraterrestrial life could challenge religious beliefs, while others see it as beneficial. Some Catholic figures — such as Vice President JD Vance and Monsignor Stephen Rossetti — view UFOs as demonic, though the Catholic Church remains open to the idea of alien life. Theologians and historians note that interest in otherworldly beings dates back centuries.

Elon Musk is all about big numbers — millions, billions, even trillions – and there are plenty of them associated with SpaceX and Musk’s plans to take the rocket maker public. The prospectus for SpaceX's initial public offering shows spending at a massive scale — greater than economic output of some countries — and about to grow much larger as Musk races to make good on his promise to hurl people to distant planets. Money raised in the initial public offering — estimated to be $75 billion — will help. The IPO could rank as the largest ever and make Musk the world's first trillionaire.

NASA has revealed the crew for its Artemis III mission, the next step in eventually landing astronauts on the moon. NASA’s Randy Bresnik, Frank Rubio, Andre Douglas and the European Space Agency’s Luca Parmitano won’t fly to the moon or land on the surface. Instead, they’ll orbit Earth while practicing docking their Orion capsule with lunar landers. The demo is targeted for 2027. NASA’s Artemis program aims to land astronauts on the moon for the first time since the 1970s.
