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.

Bringer of Light, Chapter 13: The Artemis

February 6, 2021
MThomas

While Gennaji prepares to defend himself after having revealed the Sagittarius’s location to fellow asteroid hunters, Riss discovers that trying to forget painful memories has consequences.

Riss fairly staggered out of the exercise room, more exhausted by the two-hour workout than she had expected. Increased gravity from their acceleration, plus extra weight from the rock? Or something else? Her legs felt like pieces of taffy left out in the sun too long. And there was that strange headache she couldn’t seem to shake. Maybe she was just dehydrated.

She shuffled down the corridor to her room, holding herself upright with a hand against the wall. She probably ought to go to the command center, check on the rock, talk to the crew. But first she desperately needed a rest. 

She reached her sleeping cabin and pushed the door. It seemed lighter than usual. No, not lighter. Less…dense. She shook her head and crossed the threshold. 

“Artemis. Lights.”

The sudden illumination hurt her eyes for some reason. She covered them.

“Lights at fifty percent.”

Her vision returned to normal as the lights dimmed.

No, not quite normal. Even with half-illumination, it was as if she could see perfectly. Better than perfect. The door closed behind her and she walked slowly toward her desk. The pad still plugged into the wall port seemed to hum. She gently touched its edge. Somehow it felt…transparent. Translucent. Like the pad wasn’t entirely there.

Or maybe she wasn’t?

Sighing, she slumped into the chair. Maybe it was a virus. She supposed that would explain the headache and sensitivity to brightness. But there was something different about the room. The ship. Herself.

She glanced at the motanka. 

No face. She always wondered about that.

“This doll is special. It is a protector of children,” Sergey said. “As you grow, she will grow, too.

“You mean motanka will get bigger?” she asked, eight-year-old eyes wide.

Sergey laughed. “No, dytyna. She will grow in other ways. Don’t worry. You will see.”

Riss examined the doll. Except for the cross on its face, it looked like any other doll. Two legs, two arms, long skirt. Less lifelike than the one she got from her real parents.

She picked up the doll and frowned.

Her real parents. She thought she had no memories of them. None?

No, wait. She could see something.

Her father. He gave her a doll. Once. Before they had to leave.

She squeezed her eyes shut.

Before they disappeared.

She opened her eyes again. No, she just couldn’t remember.

And looked at the doll. It had changed color.

She turned the doll around, then upside down.

Yes, it had changed color. Yellow hair, check. Black dress.

No, it was green. With light blue flowers…no, checkered red, yellow, and white patterns all over it.

That could’t be. The face was the same. The no-face.

She set the doll on her desk and flopped face-first on her bunk. What on earth was going on? Was space sickness making her lose her mind?

Weng. She needed to talk to him. Should have vidmessed him. Mars and Ceres refused their pings. Should have tried Luna.

Should have.

Magboots still on, Riss fell into a deep sleep.

Walking along the sea. Dark, artificial blue sky. Beyond that she knew lay endless darkness and empty space. Almost as empty as…

A pressure on her left hand. Weng. Holding it firmly, then gently. A squeeze followed by a caress. Like he wanted to say something to her. Like he wanted her to say something to him.

“I love the way your face looks,” Weng began.

“Stop, stop,” Riss interrupted, shaking her head.

“The blue of the Cantic Ocean,” he continued. “The blue of the sky. The constant breeze that wafts…”

Riss sighed.

“I love the way your face looks, framed by the waves of brown locks, blown by an ocean breeze.”

He smiled, then laughed.

“Hopeless romantic,” she said. “You’re just a hopeless romantic. You do know that?”

“I’m supposed to say stuff like that,” he returned. “I’m an artist. It’s what we do.”

“Oh?” she replied.

He just smiled his enigmatic smile. They fell silent.

Something was bothering him. She could tell. He’d never ask for help. Not openly. Not from her. She squeezed his hand. He sighed.

“It doesn’t look like you’ve had much time for artistry lately,” she tried.

Weng made a face. “You’re right, I haven’t.”

“So…”

He said nothing. Just coughed.

Riss looked at him as they walked, hand in hand. He stared into space. What was he thinking? She wondered. What was it he was looking for?

“I guess,” he said finally, after a long pause. “I guess you’ll be heading out again soon.”

She nodded. “You heard.”

He smiled again, looking up, above the sky.

“Sergey mentioned something about a lottery. A special asteroid of some sort.”

“Yes. A centaur. We won the rights to capture it.”

Weng shook his head. “I can’t pretend I understand how you asteroid hunters operate, but can’t you just, you know, negotiate?”

She laughed. “We did. Sort of. It’s complicated.”

She looked at him again. Her artist. Touchingly naive, stubborn and set in his ways. But that didn’t matter. He was faithful to her. Loyal to her adopted father. He had always supported her, regardless of whatever foolish thing she had said or done.

“You will come back to me, yes?” he said.

She squeezed his hand again. “If all goes well, this will be the last trip I have to make out there,” she said.

“Promise?”

“No, of course not!” she said, laughing. “No promises. No guarantees.”

“No returns,” he said. “All sales are final. Let the buyer beware!”

They giggled together. It felt good, sharing a moment with someone she could be completely honest with. Completely open.

Completely. No. She suddenly stopped and let go of his hand. They stood still.

She looked into his eyes. He was still smiling, but the smile didn’t quite reach his eyes. His face fell. It was as if, for a moment, she could see who he really was. His real face. Like a cross…

“I’m sorry,” she started.

“What?” he said. “What is it?”

“This…this isn’t…”

She looked up again. The blue sky was gone. Darkness everywhere. 

The ground fell away. Weng disappeared from her sight, his outstretched hands waving uselessly in the lunar wind. No cry escaped her lips. She stared wide-eyed at the stars. The emptiness rushed down. She rushed up to meet it.

With a start, Riss realized she was floating. Outside the ship, free floating in space. No suit. No helmet. In a panic she put her hands over her mouth. But there was no breath. No sound. Silence, only silence.

She looked down. She wasn’t wearing any clothes, none whatsoever.

This must be another dream, she thought, calming herself. Well, then, let’s see where it takes me.

Ahead lay a vortex. She smiled. A vortex, in space. Drawing her closer. She felt like putting her arms in front and swimming, as if it would make any difference.

To her surprise, it did. She felt the vortex pull at her, call her, gently coax her toward its amorphous black center. Faint clouds of burgundy and crimson whisked away as she neared. With a start she found that the vortex was not a hole at all. She reached out with both hands…

And brought a small object back to her.

A small ball. Cottony.

She cupped it. The ball dissolved into a cloud and flowed up her arms, across her entire body, dissipating in the space behind her.

Sensation returned. Gravity wells appeared before her eyes. Patterns revealed themselves. Orbits of planetary objects, trajectories of comets and asteroids. Space dust. Black matter.

She suddenly knew where she was. The happy hunting ground stretched like an enormous mine field before her, blocking her view of the inner system.

Concentrating, she willed an asteroid to approach. It was small, no more than a few meters across. She floated near it, ran her hands over its rough surface. The edges, points, indents. Mostly iron ore, with other trace minerals.

With a wave of a hand, she pulled the trace minerals out, leaving nothing but a ball of pure iron. A deft thrust into the ball; it stretched and twisted like taffy. 

Into a mask.

She held it in her hands. Looked down at it.

The mask looked back at her. She tried it on and saw herself.

Her face. 

The face of the motanka. With a cross on it. 

She screamed.

Weebles wobble — and so does Mars

February 5, 2021
MThomas

Looks like Mars doesn’t spin perfectly on its axis. In fact, it wobbles.

And no one knows why.

This makes Mars only the second planet in our solar system to exhibit what’s called the “Chandler wobble.”

The other planet?

Why, Earth, of course.

(And, no, nobody knows why. Hmm. Chandler?)

Sorry, Venus is just a lot of gas

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. 🥚

Bringer of Light, Chapter 10: The Artemis (Part 2)

January 9, 2021
MThomas

(The Artemis crew experienced strange sensations, which they believed dreams. Now the asteroid fragment from which they already extracted water for their drinking supplies is glowing…and many contain life.)

“Coop, is there any precedent for hydrocarbon-rich asteroids containing nucleic acids?”

The geologist rubbed a hand on one arm. Where Sanvi had grabbed him, Riss realized. She slowly walked toward him, and he toward her.

“Only in theory,” he said carefully. He looked at her with a strange expression. Like he was trying to figure out if she was serious, she guessed. “It’s widely believed that amino acids were first introduced to Earth by asteroid or comet bombardment.”

He stopped. “If…”

He turned to the rock.

“Why is it glowing?” Riss said quietly.

The geologist shook his head.

“I don’t know. I’m an astro-geologist, not an exobiologist.”

“Speculate.”

“Well,” he said, rubbing his arm again, “I suppose it’s possible that, if there were any RNA, the ribose could have completely hydrolyzed, so that it bonded with any freely available compounds in the rock, such as phosphorous or sulphur.”

“O-kay,” Riss said. “And if it’s not RNA?”

“It could be some other kind of enantiomer whose chiral features—”

“All right, slow down,” she interrupted. “I followed the phosphorus bit, but what on earth are you talking about?”

“Um. Sugar. Basically.”

“Sugar?”

“Yeah. Hydrocarbons have, uh, carbon, right? So, that means carbohydrates. Starches and sugars. But molecules sometimes come in pairs. Mirror images of each other. So when one of the pair affects you one way, the other might affect you another way.”

“Meaning?”

Cooper looked at Sanvi with a frightened expression.

“Drugs.”

Sanvi opened her eyes wide and took a step forward.

“Coop,” Riss said, placing herself between the two, “you had better explain yourself.”

“Drugs,” he repeated, crossing his arms and taking up a defensive posture. “Like the pills we got from Ceres base before heading out here. You know, like the ones I got for low gravity sickness. There might be something, some natural molecule in the rock that acts kind of like that.”

Riss nodded. “Okay, I can see that. So it’s possible we all got some sort of, what, psychotropic solution from this rock?”

Cooper shook his head. “I just don’t know.”

“Whaddya you mean, just don’t know?” Enoch blurted out. “I had this crazy dream. Are you saying I was stoned?”

Cooper looked at him. “You what?”

Riss interposed. “Coop, we all had dreams. Strange dreams.”

She looked at her crew members one at a time. “Isn’t that true?”

Sanvi and Enoch both nodded.

“N, no,” Cooper murmured. “It wasn’t…”

Riss looked at him intently.

“No,” Cooper said, in a stronger voice. “No, I didn’t have any dreams. I mean, I don’t remember them.”

Riss sighed. Whatever, let him keep his secrets. She glanced at her wrist panel. They should reach Zedra point in a short while. They all needed some serious sleep by then.

“Coop, what’s the other possibility? Are there any?”

Coop stared down at his feet.

“If—if it is RNA…”

He shook his head.

“No, not possible. The filter would have detected it.”

“Coop,” Sanvi cut in. “How do you know all this? I thought you said you were a astrogeologist, not an exobiologist?”

She looked more composed than before, Riss noted.

The geologist looked up. He also looked more composed, but slightly defiant. “Yes,” he replied, “but I also studied biochemistry.”

He looked at the rock again.

“I wanted to be a biologist, like my father.”

He had never discussed his father before. Riss wondered if that had something to do with his reluctance to discuss his dreams. Or lack thereof.

“So,” Sanvi said calmly. “How do you know it’s not RNA?”

Cooper paused, then slowly walked back to the console. He kept his eyes trained on Sanvi. She stood still, returning the gaze without expression. Enoch was biting a thumbnail.

The geologist stabbed at the screen for a few seconds before responding.

“RNA has ribose, which is a kind of a saccharide. It’s pretty unstable, so it could have simply dissolved into the water supply. But I don’t see any other elements like amino acids, lipids, or other proteins.”

He straightened and rubbed his eyes with the palms of both hands.

“So we could have a virus in our water?” Riss asked.

“I—I don’t think so.”

“But you’re not sure.”

“I’m a—”

“A geologist,” Enoch interrupted. “Not a doctor.”

They all looked at him. The navigator had been silent through most of the conversation. He still looked sulky, Riss thought. But also troubled, standing apart from them, arms crossed and frowning.

“Yeah,” Cooper said. “I’m a geologist. But—”

“But nothing,” Enoch said. “Viruses don’t cause dreams. I had a dream of flying. Of Hawai’i. Of the Lunar Base. You gonna tell me a virus did that?”

“I’m not saying anything for certain,” Cooper said, indignant. “I’m a scientist. I don’t like speculation. I don’t trust guesses or hunches. Just facts.”

“The facts are—”

“The facts are,” Riss cut them both off, “that we don’t have enough facts. Coop is right. It could be a virus. It could be a sugar of some sort. It could be something else, we don’t know.”

They fell silent. The rock continued to glow behind them.

“So.” Sanvi finally said. “What do we do?”

Cooper spoke up. “I think it would be a good idea to run a med check on all of us. Just in case.”

Riss nodded. “Agreed. Enoch, get over to the med dock and start setting up the diagnostic equipment.”

“Roger.”

The navigator turned to go, then stopped. “You know, Riss.”

“Uh-huh.”

“A thought just occurred to me.”

Riss crossed her arms and smiled. “A thought? You?”

Sanvi giggled. The sound made Riss feel relaxed. Finally. Maybe things might get back to normal after all.

But Enoch looked troubled still. “What about the other rock chunks?”

Sanvi stopped giggling. Cooper looked startled. Riss closed her eyes.

Shit.

They ran back to the command center.

“Sanvi, get a message out to Ceres,” Riss ordered tersely as they slid into their respective seats. “Under no circumstances are they to pulverize the rock or use any hydrocarbons from it.”

“Way ahead of you, Riss,” Sanvi replied, already starting up the comm systems.

“R—Riss,” Cooper said. “I’ll prepare a more detailed report on—whatever the computer thinks it may or may not have found.”

Riss nodded. Might be useful in case someone in the guild had questions.

More importantly, though, what would she tell Sergey? His trust in her—was it unfounded?

And Gennaji.

She bit her lip.

Lena.

Her own inexperience, her decision-making skills. Had she learned nothing?

“Riss,” Enoch said. “I got something here.”

“On the trajectory?”

“No, from Ceres.”

He gestured to his screen. They gathered around the console. An image appeared; a string of numbers and text detailing the successful capture of the two rock fragments they had launched from their transneptune position several days before.

“So they got the chunks with no problems,” Sanvi commented. “That’s a first.”

“That’s not all,” Enoch said. He scrolled down. “I found the Ceres Mining Consortium transportation record. Posted yesterday. Take a look at this.”

Riss read in mute astonishment. The rocks had already been pulverized into water and sent on to Mars. Why so soon?

“We need to get a message to the Mars Colonies, then. As well as to Ceres.” She went back to her chair. “Is there any way we can return to the happy hunting grounds faster than our current ETA?”

Enoch shook his head. “Probably not. The ion engine has been increasing our speed incrementally for each day. It’d throw everything off if we tried to recalibrate them. If we lost some weight somehow, then maybe.”

He shrugged and raised his eyebrows.

Riss caught his meaning. “No,” she stated flatly.

“If we dumped the rock, we could gain—”

“No!” she said, fiercely. “Even if that thing is worthless, it’s still ours. Not a chance.”

“What if…”

Riss turned left. “Sanvi?”

The pilot hesitated, then continued. “What if we don’t stop at Zedra point?”

“You mean, skip the refueling? We’ll run out.”

“Inertia will carry us,” Sanvi pointed out. “We’ll just have to rely on someone at Base to slow us.”

“She’s right,” Enoch said. He pointed at his console. “I just did the math. We can pick up a couple of days by skipping the refuel. And if we steer a little in the right direction, I think we can get another boost or two from Saturn or Jupiter.”

“Riss,” Sanvi said, “if we can pick up around 55 to 60 hours, we can get to Ceres without refueling.”

“You sound confident,” Riss said. “How are we doing on food and water?”

“More than enough,” Cooper said. He proffered a pad. “Even though the water may or may not be, uh.”

“Contaminated?” Sanvi suggested, smirking.

“Compromised,” Cooper retorted. “And I said ‘may.’ We still don’t really know.”

“Water with living things in it,” she replied, making a face. “Disgusting.”

The geologist shrugged. “At home in Colorado, all our well water had living things in it.”

Sanvi looked horrified.

“Didn’t know you had such a weak stomach,” Enoch chortled.

“Living things! How could you?” She shuddered.

“Weak,” he repeated.

“If you’re trying to irritate me…” Sanvi warned.

Enoch grinned and turned back to his console. “Are you irritated?”

“Yes.”

“Then it’s working.”

“All right, people,” Riss said, suppressing a chuckle. “Let’s get that message sent to Mars. They need to know what’s coming.”

Sanvi shot one last look at the navigator and bent to her task. Enoch was also diligently tapping away, swiping a pad hanging in the air to his right while checking the console in front of him. After a few minutes, he turned to Riss.

“New course input. We miss Saturn, but Jupiter lines up nicely for a gravity well push to Ceres.”

“Well done,” she responded. “Do it.”

Enoch nodded. He touched the console again. Riss once again could have sworn she felt the Artemis buzz. As if the ship were talking with them, approving the turn to starboard.

“We’ll feel stronger gravity effects as we approach point-five g,” Enoch commented.

Cooper shook his head. “The asteroid chunk will have more weight, then.”

Riss nodded. “True. So we’ll need to use more of the hydrocarbons to reduce the mass.”

They all looked at her.

“What? We already drank the water. Another couple days won’t change anything.”

Cooper relaxed his shoulders and sighed. “I wish I had your confidence.”

Enoch just laughed. “What the hell. I don’t mind flying every night.”

Riss was about to respond when a sudden exclamation from Sanvi stopped her.

“Guys, we have a problem.”

It was Riss’s turn to sigh. “Another one?”

The pilot slapped at her console. The sound echoed in the tiny command center. Plastic and metal against skin. Riss felt the ship groan in protest. Or had she just imagined that?

“Mars is refusing our pings,” Sanvi said through tight teeth.

Riss frowned. “Refusing?”

“They won’t give permission to let the message through. Something about being unable to verify non-hostile intent from unauthorized spacecraft.”

“Say what?”

Riss sat back in the command chair. This did not sound good.

“Try Ceres.”

Sanvi slapped the console again. “Already did. Same response.”

“Same? Exactly?”

“Well,” the pilot conceded. “Not a hundred percent, no.”

“Then?”

Sanvi looked directly at Riss.

“There was also a message. For you. From Gennaji.”

Riss said nothing. Her hands gripped the chair’s arms. She felt strangely calm, although she knew she looked pale. Old memories resurfaced.

“He can’t have reached Base before us,” Enoch exclaimed. “In that old rust bucket?”

“Ryan, enough,” Riss whispered. She felt energy draining from her.

“The message had been relayed from some other position,” Sanvi said. “Not sure where.”

Riss breathed out, trying to relax her grip.

“What did he have to say?”

Sanvi paused. “‘I will have my own.’”

They were silent for a moment.

Then Enoch spoke up.

“Fuck him!”

“Charmingly eloquent,” Sanvi said. “As usual.”

“Come on, Riss,” Cooper said, sounding exasperated. “What is it with this guy? What has he got against you?

Riss shook her head. “This is between him and—”

“No, it’s not!” the geologist said angrily.

She looked at him, shocked. Cooper seemed to have an aura around him, as if the air were charged with anger.

“Whatever vendetta or grudge or whatever this guy has against you affects us as well,” he continued.

He sat back in his chair, crossing his arms. “I think we have a right to know.”

Riss looked back and forth from Sanvi and Enoch, pleadingly. She could only respond weakly, “I—I’d rather not.”

“Not good enough, Riss!” Cooper said. He seemed on the verge of exploding.

“There was another woman,” Sanvi said softly.

Riss protested weakly. “No…” A dark void filled her eyes.

Enoch asked, “Gennaji and Riss had something?”

“No,” Sanvi said. She looked away. “Riss was the captain.”

“Somebody died,” Riss whispered to the darkness.

They looked at her again. She felt pale.

“Riss,” Sanvi began.

Riss stared into nothing. She felt the start of tears in the corners of her eyes.

No, she thought. Not now. Not yet.

She quickly composed herself, tugging down her shirt sleeves from tense shoulders.

“I’ll be in the gym,” she said brusquely, climbing out of the captain’s chair. “Continue on the new course to Ceres.”

Sanvi fell silent. Cooper raised a finger but then placed it against his lips, lost in thought.

She turned to go. She should have reprimanded the crew for not responding to a command, but she knew she had to get out of there.

“What’ll we say to the Mining Council?” Enoch called out.

Riss stopped on the threshold of the corridor and spoke without turning around.

“We’ll find out when we get there.”

Then she disappeared.

A sneak peek at the inside of the Red Planet

December 18, 2020
MThomas

Despite the lack of large marsquakes, the researchers were able to estimate how thick Mars’ crust is. They predict it has three layers—but possibly two—that are between 12.4 and 23 miles thick, reports Nature. Mars’ crust is considerably thinner than that of Earth, which can be up to 25 miles thick—and that’s surprising, reports Science.

https://www.smithsonianmag.com/smart-news/robotic-explorer-mars-offers-sneak-peek-mars-inner-layers-180976568/

Lots of small “Marsquakes,” but nothing big. Max M4.5.

A techtonically silent world. Might explain the weak magnetic field which allowed solar winds to rip off its atmosphere long ago.

Remember the Titan! Uh. The moon. Called Titan.

November 6, 2020
MThomas

Cyclopropenylidene is the second cyclic or closed-loop molecule detected at Titan; the first was benzene in 2003. Benzene is an organic chemical compound composed of carbon and hydrogen atoms…Cyclic molecules are crucial because they form the backbone rings for the nucleobases of DNA, according to NASA.

https://edition.cnn.com/2020/10/28/world/titan-atmosphere-molecule-chemistry-scn-trnd/index.html

The only moon in the solar system that has an atmosphere…4 times denser than the Earth, actually.

Except it rains ethane and methane and is -270C. Not exactly a place to plan a vacation.

But the organic molecules may (BIG may) hint at life of some sort.

And we only have to wait until 2034 to find out!
