Astronomers briefly thought Elon Musk’s car was an asteroid. Here’s why that points to a broader problem

Seven years after SpaceX launched Elon Musk’s cherry red sports car into orbit around our sun, astronomers unwittingly began paying attention to its movements once again.

Observers spotted and correctly identified the vehicle as it started its extraterrestrial excursion in February 2018 — after it had blasted off into space during the Falcon Heavy rocket’s splashy maiden launch. But more recently, the car spawned a high-profile case of mistaken identity as space observers mistook it for an asteroid.
Several observations of the vehicle, gathered by sweeping surveys of the night sky, were inadvertently stashed away in a database meant for miscellaneous and unknown objects, according to the International Astronomical Union’s Minor Planet Center.

An amateur astronomer noticed a string of data points in January that appeared to fit together, describing the orbit of a relatively small object that was swooping between the orbital paths of Earth and Mars.

The citizen scientist assumed the mystery object was an undocumented asteroid and promptly sent his findings to the MPC, which operates at the Harvard Smithsonian Center for Astrophysics in Cambridge, Massachusetts, as a clearinghouse that seeks to catalog all known asteroids, comets and other small celestial bodies. An astronomer there verified the finding.

And thus, the Minor Planet Center logged a new object, asteroid “2018 CN41.”

Within 24 hours, however, the center retracted the designation.

The person who originally flagged the object realized their own error, MPC astronomer Peter Veres told CNN, noticing that they had, in fact, found several uncorrelated observations of Musk’s car. And the center’s systems hadn’t caught the error.

I wanted to scatter Dad’s ashes in Antarctica. It didn’t go as planned
гей порно видео
Dressed for the coldest conditions, I step out of the zodiac and place my feet on the White Continent for the first time.

I feel a little awkward, because I’m still finding my way in this Antarctic armor. I’m wearing four layers on top, including three jackets, all of their hoods over my head. Thick winter gloves cover my fingers. In my pocket is, of all things, a bag of ashes, which adds to the bulk. I can feel the bump it makes on the right side of my jacket as I bend over and secure my snowshoes.

I brought the bag because, like many travelers, I thought spreading Dad’s ashes somewhere special would be a nice tribute. This June will be 10 years since he died, and it would have been special to share this trip to Antarctica with him. Maybe a ceremonial offering, such as the spreading of his ashes, could suffice.

I’m prepared to spread the ashes on this very walk, amongst the icebergs, mountains, penguins and glacier blue ice. But, before we set off on the snowshoe, the guide gives a safety briefing that cools my jets.

Antarctica has strict regulations — nothing should touch the ground other than our boots. No sitting. No snow angels. No packs on the ground. Do not toss away food or pour out drinks. Under no circumstances should anything be left behind, he says.

When drawing up this dream ceremony, it never occurred to me to think about any rules or regulations surrounding the spreading of ashes. Turns out, not only do ash-scattering restrictions exist, but all around the world, there are specific rules about where and how you can spread them both on land and in the water.
