Private astronaut missions to the ISS will soon require a NASA chaperone

Private astronaut missions to the ISS will soon require a NASA chaperone

During the mission, dubbed AX-1, the four-member crew spent nearly two weeks off of Earth’s surface, at least in part conducting experiments and other scientific work. Other space tourism companies like Blue Origin or Virgin Galactic only offer customers short trips that allow for a few minutes of microgravity. Among the most notable new policies … Read more

Scientists Are Using Dead Spiders as Horrifying Claw Grabbers

Scientists Are Using Dead Spiders as Horrifying Claw Grabbers

We’ve likely all killed a spider or two in the past, but what if that arachnid’s corpse could be repurposed into something useful? Well, researchers at Rice University in Texas think it can and are pioneering the field of “necrobotics” by injecting dead spiders with air to use them to grasp small objects. When Rice … Read more

Scientists Create Necrobotics to Turn Dead Spiders into Undead Zombie Robots

If you think spiders are creepy when they’re alive, just wait until you see what they can do when they’re dead. A team of engineers at Rice University in Texas successfully reanimated dead spiders to serve as mechanical grippers. That’s right. In proof that we have permanently strayed from God’s light, the team published a … Read more

Walking on Asteroid Bennu Would Be Like Stepping Into a Ball Pit, NASA Says

Walking on Asteroid Bennu Would Be Like Stepping Into a Ball Pit, NASA Says

In October 2020, a small spacecraft briefly touched down on an asteroid to snag a piece of it to bring to Earth. Almost two years later, scientists have learned that if the OSIRIS-REx spacecraft had extended its stay even a tiny bit longer, it would have sunk right into the asteroid. That’s because asteroid Bennu … Read more
