New analysis of one of Saturn’s moons suggests that it may harbor a liquid ocean. No, not the usual suspects – the new culprit is Mimas, the little moon with a big crater, which gives it more than a passing resemblance to the ‘Death Star’ from Star Wars.
…a study announced in December from a team of researchers in the journal Icarus now claims the IAU’s definition was based on astrology — a type of folklore, not science — and that it’s harming both scientific research and the popular understanding of the solar system.
I’m not sure I agree that moons of Jupiter and Saturn should be classified as “planets,” but frankly I see little difference between “dwarf planets” and “planets.”
Plus it wrecks the song I learned to remember the order…
Over the years, the SAA has been responsible for several spacecraft failures and even dictates when astronauts can and can’t perform spacewalks. As the space around Earth becomes filled with an increasing number of craft, what does the SAA mean for the future of spaceflight?
This post is from back in February 2021, but I just stumbled across it this morning and thought it was an interesting read.
Learn something new every day!
This part caught my eye…
Radiation is a colorless, tasteless, and odorless enemy…
…and I couldn’t help thinking…
It’s okay. I’m immune 😂
Anyway, the article linked above is food for thought. Whenever electronic objects pass through the SAA, which is where the loops of the Van Allen Belt dip perilously close to the Earth, the electronics get a massive amount of radiation and go haywire.
Seriously expensive to shield stuff up there — and as more and more satellites (and people) go up, so does the risk.
Riss and the crew of the Artemis have experimented with their strange new understanding of the universe – both physical and emotional. Still far away from Ceres or Mars and unable to contact those who may have been similarly affected by the asteroid, the crew has to find a way to traverse the vast space that lies ahead…
The banging on the door came again. A muffled shout from the corridor side.
Riss opened her eyes. Her feet were firmly stuck to the floor of her cabin. Having forgotten to remove her magboots. She was standing, swaying in place. Yawning, she stretched her arms over her head.
The geist practically fell through the opening doorway. Caught from behind by the navigator.
“Riss, are you, are you okay?”
“Yeah, fine, fine, Coop.” She turned to the fridge unit. “Water.”
The fridge rolled out, door opened. A pack of water came to her hand.
Cooper’s eye widened slightly. He straightened himself, brushing off Enoch’s grasp. “You seem to have everything under control.”
She laughed. “Sorry to make you all worry. Did I oversleep?”
“The opposite, actually,” Sanvi called out. Riss could see her now, leaning against the corridor wall with her arms crossed.
Sanvi nodded at Enoch. “Somebody has been demanding that we try the pitaya experiment again.”
Enoch shrugged. “I got hungry.”
Riss looked between the two of them. Suddenly she felt an enormous bond among them. Her friends. Her crew. It was as if she could see a glow around their rough edges.
She took a deep breath and smiled.
“I have a different idea. Let’s try to make the Artemis go faster.”
She was floating, feeling free at last. Unbound by any restraints, in control of herself. She finally knew who she was…but something tugged at her, something she had been searching for. Something calling her.
“No, no, I don’t want to go!”
Strong arms, gentle arms holding her. A needle pricks her upper arm.
“It’s okay, you’ll be safe. I promise.”
Shadows, sad shadows are all she can see. So sleepy.
“We’ll see you soon, varobushek.”
Riss suddenly sat up in her bunk.
Or, rather, tried to sit up. The sleep restrainer harness yanked her back down with a jolt. Feeling foolish, she pulled at the velcro and the straps floated harmlessly next to her. Rubbing her arms where the strap had dug in, she sat up again, slowly, and pulled her magboots on.
After her experience the previous night, she had decided to take no chances. The Artemis was beginning to slow down as they approached the Happy Hunting Grounds, returning the microgravity closer to its normal low. She should have used the harness every single night, but to tell the truth, she hated it.
Hated being restrained by anything.
What she couldn’t give for a gravity generator. Not feasible on a ship this size, given the energy consumption. In the meantime, time for her calcium supplements.
She touched a panel and removed a sealed pack of tablets from the drawer that popped out. She grabbed another pack of water, hesitated momentarily, then popped it open and inserted the straw.
Oh, well, she thought, downing the tablets and taking a big sip. Far too late to worry about what was in the water.
She leaned back in her bunk and took another long sip. The patterns suddenly came into view, dancing across the surfaces of the room. Then they faded, but she could see them.
Almost imperceptible. Everywhere.
The walls, the floor, the ceiling. The desk. The pad and its charge port in the wall. Her magboots.
She paused and rested her gaze on the motanka. It hadn’t changed back to its original color, still green with checkered red, white and yellow patterns on the skirt. The yellow hair had turned brown. No, red-brown.
The color of her own hair, she suddenly realized.
She drained the water pack and let it float to the ceiling. Maybe it was time to do some more experimenting.
She stretched out her hand and concentrated.
Nothing at first. Then she relaxed her hand, thinking of the motanka. As if in response, the doll lifted itself from the desk and floated across the room to her hand.
She nearly dropped it in surprise.
Just like the dragon fruit.
What else could she move?
She glanced at the pad, in its charger. It came tumbling across the room, straight at her forehead. She ducked, and it bounced off the wall behind her, falling onto the bunk.
It should have fallen up or floated. She thought again, and the pad floated upward, then into the middle of the room. She could see the patterns around it, the lines guiding it and molding it into shape. Gently she coaxed it back to its charger.
Could she open the door?
With a metallic clang the answer became readily apparent. The lights shut off, then on. The fridge moved toward her, opened up and flung a water pack, then rolled obediently back to its port. The door closed, softly this time.
She sighed. Didn’t even feel tired this time, unlike after the pitaya explosion incident in the mess earlier. Maybe with time they wouldn’t get tired at all. Or maybe it was just little things.
Or if they worked independently or together.
She looked at the doll in her hands.
The no-face still looked back. The colors—she could change them back to the way they had been. Yes, they did. Blue with yellow flowers and golden, flaxen hair.
No. She didn’t like the hair. Changed it back to brown, but a darker brown than before. Shorter, slightly wavy.
A memory spoke again to her.
“Why are you crying, moya kroshka?”
“At school, Elke called me a bad name. Right in front of the others.”
“A bad name? What kind of name?”
“Pig! They called me Russian pig!”
“You’re not a pig, kroshka. But you are Russian. And German, too.”
“I don’t wanna be Russian! I want to be just like Elke!”
Just like Elke. Just like the other kids. Not special. She clutched the motanka.
Dreams of a six-year-old. She couldn’t even remember where the school was, or what Elke looked like. Only the pain, the hurt was real. Even now, two decades later, it still hurt.
Who was she?
She wasn’t Russian. She wasn’t German. Barely remembered her mother, hardly any memories of her father at all. Just the last few moments as they made her go to sleep in the life pod.
True to his word, Sergey had helped her to find out who her birth parents were. At first. He had retrieved their passports from the life pod and was able to search for their names in the UN database. Her father was a chemical engineer, her mother an exobiologist — maybe she had even known of Coop’s father, who knows. Her parents apparently met in Italy at some sort of international conglomerate-financed exhibition on terraforming. In fact, that’s where Riss was born. But she had no memories of Italy, and few of her childhood.
Before the accident.
They had been in the midst of a family move to the Moon, to join the terraforming team, when their shuttle experienced a sudden power failure. Riss was the only survivor. A dozen others were never found again, presumed dead following the spaceship’s violent decompressive rupture.
But that hadn’t told her who they were.
German father, Russian mother. But those were just names of countries, just nationalities. Who were they? What were they like?
What did that make her?
“You can see any face you like on motanka,” Sergey told her, in the months after he gave her the doll. “That way she will grow with you, as you also grow.”
She looked at the doll. The crossed-out visage began to shift, softening features. Textures like slightly darkened skin, high cheekbones. Proud smile. Eyes…
She stifled a yelp and the doll leapt back to the desk.
The cross returned. Staring back at her from across the room.
She relaxed and exhaled, just then realizing she had been holding her breath.
The doll. It was just like her. Featureless. Easily changed. Controlled.
Was that why these new abilities scared her?
Or was it something that she was afraid to face?
She closed her eyes and stretched out a hand. The fields seemed to interact with her fingers, slipping between them. Around them. Through them. It was as if all she had to do was touch the fields, tease apart the threads of atoms and sub particles. Expand into the space between quarks and bosons.
The space holding the stuff of the universe together in delicate harmony.
Is this what they all were? What she really was? Empty space?
No. Not just space. A tension. A balance between matter and energy.
Light and dark. Being and not-being.
She (who was she?) stretched her fingers (what were they?) through threads (were they really threads? streams? filaments of subatomic connections?), touched another searcher, seeking answers like herself (self? unself?).
A familiar feeling, part dark part light, laughter and sadness.
Sanvi? Who was that? Riss? The same? Different?
Aspects of the same universe, elements and combinations of energy condensed, vibrating, expanding, contracting, interacting.
Aware of itself / herself / themselves.
Separate but together. Connected. Sharing space.
Joy. Pure bliss. Beyond the physical. Beyond…
A shock of recognition.
The room came back into focus. Her outstretched hand briefly glowed, luminescent, fingers trembling as if by a sudden jolt.
Lungs remembered to breathe.
Inhale, exhale. Eyelids blinked.
Riss. She was Riss. Sanvi was another person.
Riss sat back on the bunk, brushing back tears with the back of a hand.
Why was she crying? The experience hadn’t been painful. She tried to recall the sensations, but came up blank.
Only the separation remained. And a dim perception of the separateness of others in their own compartments.
She could no longer tell whether her crew were asleep or awake. The Artemis whispered to her. The autopilot stayed steady on its inbound course. Two more days, at least. Space was vast.
Physical space, between solar objects. Perhaps not so vast between people.
A wave of exhaustion came over her. Sleepily she beckoned for the pad again. It came to her. Programmed a wake-up alarm. Returned it. Fell back on the bed.
No restraints this time. A brief smile lingered on her face.
She had no more need for restraints.
