SpaceX will launch an uncrewed Cargo Dragon to the International Space Station early Monday on a resupply mission with increased importance after a transportation mishap derailed a flight by another U.S. cargo ship. Liftoff from pad 39A at the Kennedy Space Center is scheduled for Monday, April 21, at 4:15 a.m. EDT (0815 UTC).

New research suggests that the largest cosmic structure is even bigger and closer to Earth than we knew. It goes against scientists' models of cosmic evolution.
Scientists have known for a while that Mars currently lacks a magnetic field, and many blame that for its paltry atmosphere - with no protective shield around the planet, the solar wind was able to strip away much of the gaseous atmosphere over the course of billions of years. But, evidence has been mounting that Mars once had a magnetic field. Results from Insight, one of the Red Planet's landers, lend credence to that idea, but they also point to a strange feature - the magnetic field seemed to cover only the southern hemisphere, but not the north. A team from the University of Texas Institute for Geophysics thinks they might know why - in a recent paper, they described how a fully liquid core in Mars could create a lopsided magnetic field like the one seen in Insight’s data.
NASA's oldest active astronaut has redefined traveling "home" for your birthday, landing from the International Space Station on the same day that he turned 70.
You never know when a central supermassive black hole is going to power up and start gobbling matter. Contrary to the popular view that these monsters are constantly devouring nearby stars and gas clouds, it turns out they spend part of their existence dormant and inactive. New observations from the European Space Agency's XMM-Newton spacecraft opened a window on the "turn on event" for one of these monsters in a distant galaxy.
In a recent paper, a team of researchers indicated that photosynthetic bacteria could exist just beneath the snow and ice around Mars' mid-latitudes. If true, this could be the most easily accessible place to look for present-day life on Mars.
The solar system is currently embedded deep within the Local Bubble, a region of relatively low density stretching for a thousand light-years across. It was carved millions of years ago by a chain of supernova explosions. And the evidence for it is right under our feet.
