“I’ll be signing off here, soon.” - InSight, Dec 20th 2022

“So, Human Andrea? Why we have landed on the [Planet of the War God]?”

The human before xem, entrenched in gear and insulated materials, face unseeable through the dark transparent mineral making up what they see through, spoke, “I was wondering if someone had, well, returned something.” Xir observed the lingering periwinkle across her nape and shoulders, tinting the usual peppy green she exuded.

“What is there to return? Humanity had never inhabited the [Planet of the War God], I believe. You achieved mass FTL travel before you learnt planet terraforming.”

“Hah,” the female laughed, “We may not have inhabited [Mars] but we did send… rovers. To see what it was like. We had planned, or discussed at the least, the inhabitability of it.”

They trudged through the barren dirt, Andrea staring determinately in one direction, likely observing a tracker of some sort on their HUD. Xir curiousity eventually got the better of xem.

“What, exactly, are you looking for, Human Andrea?”

The woman huffed, amused, “Well, I’m looking for the rovers, of course.”

“But why? Surely, by now, the rovers would’ve broken down?”

“Oh, probably.” Andrea’s body language, from what they could observe, was amused. Deeply so, even. The spike of yellow-green, followed by a melancholy purple deepened from the prior periwinkle cemented the fact. Deeply amused by xir confusion yet quite sad about their topic of conversation.

“I��m looking for InSight, mostly, but Sojourner, Spirit, Perseverance, or Curiousity are fine too. Maybe i’ll find Opportunity, but… Oh! Well. My scanners are showing that all of them are still here.”

The spike of wistfulness was unexpected, an almost positive tint to her words.

“You had said you were wondering if someone have returned something, why ‘returned’?”

“I was wondering if someone remembered them.” Here, it was sadness.

Xir blinked, or at least, that’s what xey believed how Human Andrea would describe xir Sight-Reset. Xey were blinded by the [spectrum of the sky] that flowed through her green.

“You are sad, that no one seems to have remembered these inconsequential rovers, yet you are… happy? That they are here for you to find?”

A spike of irritation, quickly washed away by resignment. “We humans pack bond to anything, Scylla, they’re not inconsequential to me.”

Xey do not believe that long-[powerless][dead][lost][depleted] rovers had impact on Human Andrea’s life, short as her existence (in terms of a human) had been. Still, xey trudged forward with the young adult, silent and grave as Human Andrea walked, a [ceremony of the dead] march, for comrades lost.

If xey had a phrase to describe it… ah, what was that saying in the [Lands of the Pariahs] of their home?

‘For as long as you exist, in memory or in bone, there is neither death nor [death in memory]’

Some notes about this for clarification and other stuff below :D

Andrea means Manly, and i thought it was fitting when i searched up the name halfway through writing.

Scylla, the alien, is a synaesthetic species wihout ‘eyes’ Xey are capable of seeing emotion (although everyone’s emotions have different colours. There is no universality to it. Someone’s anger could be a deep dark blue, for example, not a plain red.)

The ‘body language’ Scylla is referring to is, in fact, the synaesthesia that ripples with Andrea’s movements and emotions.

Scylla is indeed named after a deep sea greek monster, no i do not know why, but it is a nickname, not xir actual name (andrea gave it to xem after failing to pronounce xir actual name several times)

The phrases or words in square brackets are words that are being transliterated (if i’m using that word correctly) they are essentially words that i would’ve liked to have an english word for, or thought wouldn’t have the same terminology for an alien species.

Yes, i chose to make xem use ‘planet of the war god’ because i wanted to.

‘Spectrum of the sky’ is ‘rainbow’ if that wasn’t obvious.

the four phrases/words in a row were for long-dead except meant to be a more ‘general’ term for ‘loss of existence’ where ‘loss of existence’ wouldn’t have been gramatically or thematically correct.

‘Ceremony of the dead’ is indeed ‘funeral’ and, ‘death in memory’ is for a word i wish exists. It would make my poetry so much easier.

The ‘Land of the Pariahs’ mentioned is a barren desert on Scylla’s homeland. Nomads travel it, and are known for the hundreds of stories passed down, growing generation by generation, of pictures and pieces of lives once lived.

Scylla thinks the rovers had no impact on Andrea because they were a good few decades ago, actually. The newer ones were later retrieved, but Andrea had heard about these ones from grandparents etc. and fell in love with them.

This was written upon my knowledge of InSight’s loss of power, because of the dust build up on it’s solar panels. I pay my respects to the lander, and wish whatever tiny sliver of existence it had a peaceful future exploration of things that we do not know.

Finally, thank you for reading this! I hope you have a nice day/night and may we one day give our rovers and drones and landers their respectful resting places.

After Three Years on Mars, NASA's Ingenuity Helicopter Mission Ends

"The end of an era. One of its main rotor blades is damaged, and the helicopter will not fly again. While the helicopter remains upright and in communication with ground controllers, imagery of its Jan. 18 flight sent to Earth this week indicates one or more of its rotor blades sustained damage during landing and it is no longer capable of flight." #ThanksIngenuity #ThanksIngenuity

Mars dust storms: understanding and mitigating their impact

Mars, our intriguing neighbor in the solar system, has fascinated scientists and dreamers alike for generations. One of the many challenges of exploring and potentially living on Mars is its frequent and intense dust storms. These storms can cover the entire planet, affecting visibility, equipment, and even solar power generation. Let's dive into what these storms are, why they matter, and how we can mitigate their impact.

What are Mars dust storms?

Mars dust storms are massive events where strong winds lift the planet’s fine dust particles into the atmosphere. These storms can be local, regional, or even global, sometimes enveloping Mars for weeks or months. Unlike Earth, Mars lacks vegetation and large bodies of water to keep dust in place, making the Martian surface particularly prone to these storms.

Why do they matter?

Visibility and navigation

During a dust storm, visibility on the Martian surface can drop to almost zero. This makes navigation for rovers and potential human explorers extremely difficult. Imagine trying to drive through a blizzard, but instead of snow, you’re surrounded by tiny dust particles that can obscure everything around you.

Equipment damage

Martian dust is not just a visibility issue; it can be abrasive and corrosive. The fine particles can infiltrate machinery, clogging moving parts and reducing the lifespan of equipment. For instance, NASA’s Spirit rover faced significant challenges due to dust accumulation, which eventually contributed to its end.

Power generation

Many Mars missions rely on solar panels for energy. Dust accumulation on these panels can drastically reduce their efficiency. During dust storms, the thick clouds of dust can block sunlight, cutting off power sources for critical systems. This was a significant challenge for the Opportunity rover, which lost contact with Earth during a planet-wide dust storm in 2018.

How can we mitigate their impact?

Advanced design

Designing equipment that can withstand the harsh conditions of Mars is crucial. This includes using materials that are resistant to abrasion and developing seals that prevent dust from entering sensitive components. Rovers and other machines may need self-cleaning mechanisms to keep dust off solar panels and cameras.

Energy solutions

Diversifying energy sources can help mitigate the impact of dust storms. While solar power is a popular choice, incorporating nuclear power or other alternative energy sources can provide a reliable backup during long periods of low sunlight.

Weather forecasting

Improving our ability to predict dust storms can help mission planners prepare and react appropriately. Just as we have weather satellites on Earth, similar technology on Mars could provide advanced warnings, allowing equipment to be powered down or repositioned to minimize damage.

Human adaptation

Future human explorers will need to be equipped with habitats and suits designed to handle the dust. This includes air filtration systems to keep living spaces dust-free and protective gear to prevent inhalation and skin contact.

Mars dust storms are a formidable challenge for exploration and potential colonization. By understanding their nature and developing innovative solutions to mitigate their impact, we can continue to explore the Red Planet safely and effectively. As we advance our technology and knowledge, the dream of living and working on Mars becomes ever more achievable.

Exploring Mars is not just about overcoming obstacles but also about embracing the spirit of discovery and innovation. With each step forward, we get closer to turning the vision of life on Mars into a reality.

First Man: Neil Armstrong

[deep-space-netwerk]

So Venus is my favorite planet in the solar system - everything about it is just so weird.

It has this extraordinarily dense atmosphere that by all accounts shouldn't exist - Venus is close enough to the sun (and therefore hot enough) that the atmosphere should have literally evaporated away, just like Mercury's. We think Earth manages to keep its atmosphere by virtue of our magnetic field, but Venus doesn't even have that going for it. While Venus is probably volcanically active, it definitely doesn't have an internal magnetic dynamo, so whatever form of volcanism it has going on is very different from ours. And, it spins backwards! For some reason!!

But, for as many mysteries as Venus has, the United States really hasn't spent much time investigating it. The Soviet Union, on the other hand, sent no less than 16 probes to Venus between 1961 and 1984 as part of the Venera program - most of them looked like this!

The Soviet Union had a very different approach to space than the United States. NASA missions are typically extremely risk averse, and the spacecraft we launch are generally very expensive one-offs that have only one chance to succeed or fail.

It's lead to some really amazing science, but to put it into perspective, the Mars Opportunity rover only had to survive on Mars for 90 days for the mission to be declared a complete success. That thing lasted 15 years. I love the Opportunity rover as much as any self-respecting NASA engineer, but how much extra time and money did we spend that we didn't technically "need" to for it to last 60x longer than required?

Anyway, all to say, the Soviet Union took a more incremental approach, where failures were far less devastating. The Venera 9 through 14 probes were designed to land on the surface of Venus, and survive long enough to take a picture with two cameras - not an easy task, but a fairly straightforward goal compared to NASA standards. They had…mixed results.

Venera 9 managed to take a picture with one camera, but the other one's lens cap didn't deploy.

Venera 10 also managed to take a picture with one camera, but again the other lens cap didn't deploy.

Venera 11 took no pictures - neither lens cap deployed this time.

Venera 12 also took no pictures - because again, neither lens cap deployed.

Lotta problems with lens caps.

For Venera 13 and 14, in addition to the cameras they sent a device to sample the Venusian "soil". Upon landing, the arm was supposed to swing down and analyze the surface it touched - it was a simple mechanism that couldn't be re-deployed or adjusted after the first go.

This time, both lens caps FINALLY ejected perfectly, and we were treated to these marvelous, eerie pictures of the Venus landscape:

However, when the Venera 14 soil sampler arm deployed, instead of sampling the Venus surface, it managed to swing down and land perfectly on….an ejected lens cap.

Think we're the only planet with life? 350mp quality. Remember to download to your phone and zoom in. Gets even more beautiful. Yes this is a nebula, yes I know there’s no life in a nebula. Of course these are not real photos. Duh!

[stellanix]

hey! did you know that the mars reconnaissance orbiter, a nasa spacecraft in orbit around mars since 2006, has imaged nearly the entire planet's surface at a resolution of 6 meters per pixel?

did you also know that scientists have put all that data into the form of a 3D globe that can be explored for free in your browser?

it's the coolest fucking thing and i've spent hours and hours just getting lost in it

Sad day for Martians,

Ingenuity, the ‘little helicopter that could’, the first ever helicopter to fly on another planet is down. It took its final flight on the 18th of January where one or more of its roter blades were damaged.

We weren’t even sure it was possible to fly a helicopter on Mars before Ingenuity, and yet this tiny little shoe box of a helicopter managed to fly in an atmosphere less than 1% as dense as Earth’s, flying a total of 72 times in the last 3 years, far exceeding the 5 planned flights.

Having arrived on Mars hitched to the Perseverance rover’s belly, this little guy has spent these 3 years scoutting ahead for Perseverance. But now Perseverance will have to continue its mission without Ingenuity. For the first time since its creation, Perseverance is on its own in that endless red desert.
