“Wright Brothers’ moment” – helicopters on Mars

April 19, 2021
MThomas

“We together flew on Mars. We together have our Wright brothers moment.”

https://www.washingtonpost.com/technology/2021/04/19/nasa-ingenuity-helicopter-mars/

Yeah, yeah, I know. Technically, a German immigrant in Connecticut flew a plane before Orville and Wilbur.

But PR counts. Kudos, NASA!

X-Rays from Uranus!

April 5, 2021

Two-ringed and sideways gas giant

The gag practically writes itself…

…but seriously, this is neat. One source of the X-Rays is the Sun (it also bounces off of Jupiter and Saturn). But there may be yet another source…perhaps the rings of Uranus or the planet itself.

And no, it’s not really pink. That’s just a Chandra X-ray image.

Shame, really.

Space elevators, revisited (and even possible)

“Technical-wise, it’s kind of ready” (Prof. George Zhu of York University)

The possibilities…the tether doesn’t actually have to touch the ground. Basically, you put up a satellite with two tethers (one for things going up, one for things going down) and then have a rocket sent up and attach to the tether.

The tether would then push the payload the rest of the way into outer space (as the article points out, space begins at 62 miles above sea level, but 98% of the weight of rockets is used to break away from the Earth’s gravity to that point).

Now, this article was published on April 1st, so I’m really hoping it’s not a prank…

(Also, wordpress looks REALLY BAD today for some reason. Wth? This “block” style is clunky AF and looks more like Netscape ca. 1996)

“Potentially hazardous asteroid” approaching Earth

March 22, 2021
MThomas

This is how I’ll get a photo of 2001 F032 for its next pass in 2052.

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.

Still, they persevered!

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, Venus is just a lot of gas

February 4, 2021
MThomas

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
MThomas

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.

https://newatlas.com/space/magnetic-reconnection-rocket-thruster-concept-spaceflight-mars/

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.. 🚀

35 Years Ago: Remembering the Challenger

January 28, 2021
MThomas

It’s hard to believe that it’s been 35 years since the disaster that claimed the lives of all seven Space Shuttle Challenger crew members.

I remember it well. Being sent home early without being told. Watching the TV news at home in silent shock with my parents and younger siblings, tears streaming down our faces.

President Reagan’s speech at Congress, made in the place of the traditional State of the Union address, ended with “they slipped the surly bonds of Earth…and touched the face of God.” Probably the finest and most decent thing he ever did (even my parents, who voted for Jimmy Carter and Walter Mondale and intensely disliked Reagan and everything he stood for, couldn’t help but be moved by his words that day).

Thoughtless jokes circulated our school the next week or two. (“What’s the last thing Christa MacAuliffe said to her husband? “You feed the dog; I’ll feed the fish.”)

Even today, we focus on the school teacher who died and almost ignore the rest of the crew. Something like three dozen schools now bear her name. But NASA engineers have never forgotten. They just find it so difficult, so painful to write and talk about their friends and colleagues who perished.

There was a morbid fascination with the way in which the Challenger crew met their fate. My friends came up with all sorts of gruesome stories they claimed to have “heard,” mostly about body parts washing up on beaches around the Caribbean.

The fact is, we were traumatized. Kids do all sorts of insane things to hide their fears, insecurity, and general inability to answer the question what am I supposed to feel/do/say about this?

Challenger marked a turning point in the US space program. It set NASA back in many ways but also provided great insight into what needed to be fixed, what needed to be done to push forward our knowledge of space and the great beyond.

There is/was no going back. Humanity is a space-faring race and must continue to strive to reach beyond its grasp…”Or what’s a heaven for?”

Remember, honor.

Emulate.

Onward and upward.

Whatever happened to the “spaceplane”?

January 27, 2021
MThomas

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.”

Blue Jets, Red Sprites, Trolls, and Elves in Space

January 25, 2021
MThomas

“Blue jets” rise up from clouds.

Above the lightning, “red sprites” can be seen (plasma discharges).

Known about since 1886, not photographed until 1989….and now known to occur on Jupiter.

Check out this page for some amazing photos…

“NASA captures blue jets and red sprites above thunderstorms from space” (somebody needs to help Forbes with its grammar…”from space” is a misplaced modifier…)
