A Near Earth Asteroid (NEA), also known as 2018VP1, is heading towards Earth and is predicted to pass near Earth on November 2, one day before the US election day. The asteroid, first detected in November 2018, has roughly 2 metres in diameter and has a 0,41% chance of impacting Earth. The Center for Near-Earth Object Studies (CNEOS), from Nasa’s Jet Propulsion Laboratory, has predicted three potential impacts "based on 21 observations spanning 12.968 days," but a direct impact is most unlikely.

"Just keep roving, roving, roving" – NASA's Curiosity is taking a mile-long Mars road trip this summer
Stitched together from 28 images, NASA's Curiosity Mars rover captured this view from "Greenheugh Pediment" on April 9, 2020, the 2,729th Martian day, or sol, of the mission. In the foreground is the pediment's sandstone cap. At center is the "clay-bearing unit"; the floor of Gale Crater is in the distance.

NASA's Mars rover Curiosity is going on a road trip this summer. Curiosity has already started it's mile-long trip to a part of Mount Sharp called the "sulfate-bearing unit" where it will search for "clues how climate on Mars and its prospects for life changed nearly 3 billion years ago."

Curiosity travels with a speed between 82 to 328 feet per hour. The rover will complete part of the trip on autopilot but can't make the trip "entirely without humans in the loop." According to Matt Gildner, the lead rover driver at JPL, Curiosity has "the ability to make simple decisions along the way to avoid large rocks or risky terrain" and it only stops if it doesn't have enough information to complete a drive on its own."
