Hazardous asteroid!? Call out Bruce Willis!
No worries. “Close to Earth” in this is 1.25 million miles. But it’s a great chance to find out more about the early solar system.

Warp drive is no longer science fiction
March 2, 2021
“Many people in the field of science are aware of the Alcubierre Drive and believe that warp drives are unphysical because of the need for negative energy,” said Alexey Bobrick, scientist and astrophysicist at Lund University, according to a press release. “This, however, is no longer correct.”

There can be only response to this news…
Still, they persevered!
February 18, 2021
Great job, NASA! Landing on Mars is always a tricky business.
Now all Perseverance has to do is find traces of life, save it without contamination, and then wait for another rocket, another rover, and a satellite to get in orbit so the samples can be sent back to Earth.
Piece of cake, right?

Sorry, there’s no “Planet X”
February 16, 2021
Critics of the Planet Nine claim said the apparent clustering of the discovered TNOs might only be because that’s where telescopes were looking or were most sensitive.

If you are looking to find evidence to prove your theory, it’s much easier to find what you’re looking for.
You should instead try to find evidence to disprove your theory, and then ask at least two more people you don’t know (or even better, generally disagree with) to try to find evidence to support your theory.
“Seek and ye shall find” is a terrible way to support a claim. Have the courage to challenge your beliefs.
Also, it’s Planet X, not 9. Pluto is a planet. So there, Neil deGrasse Tyson. :-p
Maybe there is Hope, after all
February 10, 2021
Congratulations, UAE! The Hope Probe (al-Amal) successfully entered Mars orbit on February 9th.
Made in the US (Boulder, Colorado) and the United Arab Emirates (Dubai) and launched from Japan, it shows what hat can be accomplished through international cooperation instead of competition.
Maybe it is truly Hope, after all, and not just for Arab states.
Sorry, Venus is just a lot of gas
February 4, 2021
There’s a reason I didn’t post a while ago about the supposed “there’s life in the clouds of Venus” finding.
It was just a big load of gas.
Sorry, folks. Venus is a big rotten egg. 🥚

Magnetic reconnection plasma thruster: Not too fast, not too slow, juuuust right
February 4, 2021
A crewed mission to Mars may be more practical thanks to a new rocket concept developed by Fatima Ebrahimi, a physicist at the US Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), that uses magnetic fields to generate thrust.

Looks good so far…
…although it’s just a computer simulation right now and the magnetic thruster model hasn’t even been built yet.
Ah, well, just repurpose an existing ion thruster, right?
Hmm. I’m not a rocket scientist, but.. 🚀
Whatever happened to the “spaceplane”?
January 27, 2021
NASA ended the US’s interest in spaceplanes when it scrapped the shuttle fleet a decade ago.
But other space agencies and private companies in other countries are very much in the game. ESA, India, even the UK.
And, of course…
Whichever future the spaceplane does have, it will involve China. “We know very little about the launch [of China’s experimental spaceplane],” says Deville. “But it shows that China is serious about developing its spaceplane concepts.”

How to get a new tooth in Japan
January 23, 2021
This past Thursday I got a metal spike screwed into my jaw.
And it hurt.
But not as badly as I feared. To be honest, it’s all my fault. Well, all my 20-year-old-self’s fault. Too much soda and not enough brushing and flossing in college.
Damn you, Dr. Pepper!

Hey, everyone! If you look up at the right time, you can…
Uh. Yeah, anyway.
