On Friday, a small asteroid called 2018 CB will safely whiz by Earth, posing absolutely no threat to humanity. It will get pretty close to our pale blue dot, however, giving Earth a much-needed hug.

According to NASA, the asteroid will pass our planet at around 5:30 p.m. Eastern (2:30 p.m. Pacific) at a distance of about 39,000 miles (64,000 kilometers). That’s only one-fifth of the distance between Earth and our moon, making this a pretty close encounter. Still, the asteroid is just a smol boy — it’s likely between 50 and 130 feet (15 and 40 meters) in size. It’s like a flying kitten, minus all the biting and scratching.

“Although 2018 CB is quite small, it might well be larger than the asteroid that entered the atmosphere over Chelyabinsk, Russia, almost exactly five years ago, in 2013,” Paul Chodas, manager of the Center for Near-Earth Object Studies at NASA’s Jet Propulsion Laboratory in Pasadena, California, says in a press release. “Asteroids of this size do not often approach this close to our planet — maybe only once or twice a year.”

Surprisingly, 2018 CB and another asteroid that passed us this week — 2018 CC — were discovered on Sunday, February 4. Both were spotted by astronomers at the Catalina Sky Survey (CSS) in Arizona.

For those hoping to get whacked in the face by an asteroid: I’m sorry. This tiny asteroid means no harm — it just wants to take a close peek at Earth and then pass onward into the void.

Google celebrated the life of Mary G. Ross on Thursday, with a commemorative doodle on what would have been the pioneer aerospace scientist’s 110th birthday. Ross, a Native American female engineer, helped develop some of the first concepts for flyby missions past Venus and Mars, paving the way for humans to explore the stars and visit other planets. Ross proudly described some of her most important moments this way: “I was the pencil pusher, doing a lot of research. My state of the art tools were a slide rule and a Frieden computer.”

SpaceX’s manned launches are taking one step closer to reality. New images published this week shows how Elon Musk’s space-faring firm is preparing to send its first humans into space on the new Crew Dragon capsule. The flights, alongside missions planned with Boeing’s CST-100 Starliner, will be the first to send American astronauts into space on board a commercial spacecraft.

SpaceX has put its latest Falcon 9 through its paces. On Thursday, the space-faring firm shared two images of its first “Block 5” rocket, having successfully completed two missions in the space of three months. The scorched booster is integral to the company’s future plans to launch the same Falcon 9 rocket twice in just 24 hours.

Sorry, Elon Musk, but Beaker is now the first scientist to colonize Mars. NASA published a high-resolution photo of a dust storm on Mars’ south pole, revealing a case of pareidolia, the psychological phenomenon of seeing faces or shapes in unrelated objects. The appearance of Beaker was so well-defined in the Martian landscape that even the agency couldn’t deny his appearance. Meep.

Mars is kind of a bummer: That place is a hotbed of dynamic dust storms that got so big in recent months that they encircled the entire planet. Those conditions, sure to be a challenge for future Mars colonies, are a buzzkill for NASA’s Opportunity Rover right now: A dust storm forced the droid, which has been roaming Mars for 14 years, to shut down in June, and it’s still turned off today.
