NASA's newest space telescope rocketed toward orbit Tuesday to map the entire sky like never before a sweeping look at hundreds of millions of galaxies and their shared cosmic glow since the beginning of time. SpaceX launched the Spherex observatory from California, putting it on course to fly over Earth's poles. Tagging along were four suitcase-size satellites to study the sun. The USD 488 million Spherex mission aims to explain how galaxies formed and evolved over billions of years, and how the universe expanded so fast in its first moments. Closer to home in our own Milky Way galaxy, Spherex will hunt for water and other ingredients of life in the icy clouds between stars where new solar systems emerge. The cone-shaped Spherex at 1,110 pounds (500 kilograms) or the heft of a grand piano will take six months to map the entire sky with its infrared eyes and wide field of view. Four full-sky surveys are planned over two years, as the telescope circles the globe from pole to pole
A privately owned lunar lander touched down on the moon with a drill, drone and rovers for NASA and other customers Thursday, but quickly ran into trouble and may have fallen over. Intuitive Machines said it was uncertain whether its Athena lander was upright near the moon's south pole standing 15 feet (4.7 meters) tall or lying sideways like its first spacecraft from a year ago. Controllers rushed to turn off some of the lander's equipment to conserve power while trying to determine what went wrong. It was the second moon landing this week by a Texas company under NASA's commercial lunar delivery programme. Sunday's touchdown was a complete success. The company's newest Athena lander dropped out of lunar orbit as planned. The hourlong descent appeared to go well until the final approach when the laser navigation system began acting up. It took a while for Mission Control to confirm touchdown. We're on the surface, reported mission director and co-founder Tim Crain. A few minutes
NASA is switching off two science instruments on its long-running twin Voyager spacecraft to save power. The space agency said Wednesday an instrument on Voyager 2 that measures charged particles and cosmic rays will shut off later this month. Last week, NASA powered down an instrument on Voyager 1 designed to study cosmic rays. The energy-saving moves were necessary to extend their missions, Voyager project manager Suzanne Dodd at the NASA Jet Propulsion Laboratory said in a statement. The twin spacecraft launched in 1977 and are currently in interstellar space, or the space between stars. Voyager 1 discovered a thin ring around Jupiter and several of Saturn's moons, and Voyager 2 is the only spacecraft to visit Uranus and Neptune. Each spacecraft still has three instruments apiece to study the sun's protective bubble and the swath of space beyond. Voyager 1 is over 15 billion miles (24.14 billion kilometers) from Earth and Voyager 2 is over 13 billion miles (20.92 billion ...
NASA's two stuck astronauts are just a few weeks away from finally returning to Earth after nine months in space. Butch Wilmore and Suni Williams have to wait until their replacements arrive at the International Space Station next week before they can check out later this month. They'll be joined on their SpaceX ride home by two astronauts who launched by themselves in September alongside two empty seats. During a news conference Tuesday, Wilmore said that while politics is part of life, it did not play into his and Williams' return, moved up a couple weeks thanks to a change in SpaceX capsules. President Donald Trump and SpaceX's Elon Musk said at the end of January that they wanted to accelerate the astronauts' return, blaming the previous administration. But Williams, in response to a question, did take issue with Musk's recent call to dump the space station in two years, rather than waiting until NASA's projected deorbit in 2031. She noted all the scientific research being ...
