Do you think someone will remember us?
DEEP TIME was originally published as an accordion-fold comic glued into a circular shape, so the story could be read backwards and forwards from any starting panel. Physical editions of DEEP TIME printed in bright red and teal risograph are avaliable in my shop.

What do you mean by Venus floating cities?
I'm hoping to write a science fiction story about visiting Venus as part of the space race and I would love your input
Alright so the thing with Venus is that we're all very familiar with her horrible hell-death clouds and 900°F surface temperatures. We all understand the surface of Venus is not a fun place for humans to be.
Tumblr media
But, nobody ever talks about the fact that ABOVE the hell-death clouds, Venus is a paradise. The most Earth-like environment we know of in the solar system, beyond Earth itself, is actually in the skies of Venus.
About 30 miles above the surface, the pressure is ~1 atmosphere, and the temperature ranges from 30 - 100°F, which is Happy Human™ standard pressure and temperature.
What's more, a breathable mix of oxygen and nitrogen provides over 60% the lifting power on Venus that helium does on Earth. In other words, a balloon full of human-breathable air would float to the habitable range of Venus's atmosphere. We could float a ship with the very air we breathe.
The other great thing about this is that it avoids one of the big problems with Mars colonization. On Mars, any habitat on the surface full of breathable air is vulnerable to leaks and explosive decompression, a la the Martian.
Tumblr media
Floating on Venus, a balloon full of breathable air doesn't have a significant pressure difference between the inside and the outside. Which means, any leaks or tears would be very slow and manageable. You could fix that shit with duct tape!
Similarly, because the environment outside the balloon is so Earth-like, humans living there wouldn't need any big fancy pressurized suits for extravehicular work. We'd need air to breathe, maybe some heat protection, and protection against the acid rain. That's it. 
Venus also provides the tools to keep us fed! It's atmosphere is made primarily of carbon dioxide, even above the dense horrible clouds. What likes carbon dioxide? Plants from Earth!! Lets grow FOOD on FLOATING PLATFORMS in the SKIES of VENUS.
This whole idea actually came out of a NASA effort exploring potential Venus colonization. The program was called HAVOC - the High Altitude Venus Operational Concept.
It hasn't really gone anywhere, and as far as I know there are no real plans to revisit it. Unfortunately, from a practicality standpoint, Mars is a much more viable target for human colonization. Not only is it better poised for outer solar system exploration, being farther away from the sun, but living on Venus would come with too many complicated contingencies. In the event of a major failure on Venus, you'd need to fly to another base, or fuck off all the way to orbit. I understand why people aren't really in a hurry to live somewhere where landing on the surface means certain death.
But that doesn't mean I won't be forever and always enamored by the skies of Venus. Here's one of the artist concepts to come out of HAVOC.

I want to be there.

I feel like nobody on Tumblr knows that the international space station is being discontinued.
Did you know that? In less than a decade it will be gone

It’s Girl Scout Day! March 12, 2024, is the 112th birthday of Girl Scouts in the United States, and to celebrate, we’re sharing a lithograph of the Girl Scout alumnae who became NASA astronauts.
Girl Scouts learn to work together, build community, embrace adventurousness and curiosity, and develop leadership skills—all of which come in handy as an astronaut. For example, former Scouts Christina Koch and Jessica Meir worked together to make history on Oct. 18, 2019, when they performed the first all-woman spacewalk.
Pam Melroy is one of only two women to command a space shuttle and became NASA’s deputy administrator on June 21, 2021.
Nicole Mann was the first Indigenous woman from NASA to go to space when she launched to the International Space Station on Oct. 5, 2022. Currently, Loral O’Hara is aboard the space station, conducting science experiments and research.
Participating in thoughtful activities in leadership and STEM in Girl Scouts has empowered and inspired generations of girls to explore space, and we can’t wait to meet the future generations who will venture to the Moon and beyond.

An incredible, record-smashing, pioneering mission.
Rest well, Ginny. Thank you for all you taught us.

Chandrayaan-3.
India has become the first country to land at the lunar south pole, and we consider this very cool space news. Among the very coolest of space news, perhaps. And truth be told it is truly *monumental*. While many are discussing the usual geopolitical gossip that seemingly goes in tandem with such cool space news, the significance of the landing not for any one nation, but potentially for the human race, is huge. So today, to the nation of India, its brilliant scientists at Isro, and all those who worked towards #chandrayaan3, we salute your fine, very cool space work.
One of the mission's principal aims will be to search for water-based ice that, scientists believe, could support future human habitation on the Moon. However, we would ask you to spare a thought at this time for the plucky little rover, who will wizz (albeit slowly) around the Moon's south pole for one lunar day (around 14 Earth days.) Named Pragyan, which means “wisdom” in Sanskrit, the rover will analyze the elemental composition of the Moon’s surface, and assess the composition of elements like magnesium and aluminium in the lunar soil around the landing site. 
But we can't help but think of this cute little rover, its six wheels leaving imprints of Isro and India’s national emblem on the lunar surface, up there frightened, away from home, all alone :(

Planetary Nebula NGC 2440
Planetary nebula NGC 2440 is a relic of a star once like our Sun that has cast off its outer layers of gas, forming a colorful cocoon around the star's remaining core.

We are going to the Moon!
At 1:47 a.m. EST on Nov. 16, 2022, our Orion spacecraft launched aboard the Space Launch System (SLS) rocket from historic Launch Complex 39B at NASA’s Kennedy Space Center in Florida on a path to the Moon, officially beginning the Artemis I mission.
This mission is the first integrated test of NASA’s deep space exploration systems: the Orion spacecraft, the SLS rocket, and Kennedy ground systems. This is the very first time this rocket and spacecraft have flown together, and it’s the first of many Artemis missions to the Moon. Artemis I is uncrewed, but it lays the groundwork for increasingly complex missions that will land humans on the lunar surface, including the first woman and the first person of color to do so.
With Artemis, we will build a long-term human presence on the Moon and prepare humanity for future exploration plans to Mars and beyond.
See more photos of Artemis I on our Flickr.
