When I see a picture like this, it is impossible not to feel energized about the future. I think it is so important for people to understand the profound implications of sending humans to another planet: - We will develop groundbreaking technologies in propulsion, habitability, power generation, in-situ resource utilization, and manufacturing—unlocking mission optionality from the Moon to Mars and beyond. - We will create systems, countermeasures, and pharmaceuticals to sustain human life in extreme conditions, addressing challenges like radiation and microgravity over extended durations. - These advancements will form the foundation for lower-cost, more frequent crewed and robotic missions across the solar system, creating a flywheel effect to accelerate world-changing discoveries. - The pioneering science, technology, and knowledge we gain will benefit life on Earth—economically, technologically, and socially—for all humankind. - This achievement will enable humanity to survive beyond Earth, serving as a hedge against catastrophic events that have shaped our planet’s past and will inevitably happen again. It is a critical step in overcoming the Great Filter. - While peaceful exploration and discovery remain the ultimate goals, space is also the strategic 'high ground'. It is America’s responsibility to lead—to ensure national security, maintain competitiveness and secure our place in this rapidly approaching & exciting future. Achieving such an outrageous endeavor--like landing American astronauts on another planet—will inspire generations of dreamers to build upon these accomplishments, set even bolder goals, and drive humankind’s greatest adventure forward 🇺🇸

Last week @Soph_astro, @astro_hathaway and I took turns imaging each other’s internal organs for the @CNES EchoFinder-2 experiment.  This experiment aims to use augmented reality and artificial intelligence to allow astronauts without medical or ultrasound expertise to perform scans without any support from Earth.  This type of technology could prove invaluable for remote medical monitoring scenarios both on Earth and for @NASAArtemis missions to the Moon and Mars.

So much captured in this photograph. Joy & pain, family & flight, human & hardware. Love this! Go Crew-13!
Leaving Earth is hard. Leaving your family behind us harder. Before driving to the launch pad to fly to the @Space_Station; @csa_asc Astronaut, @Astro_Kutryk reached through the window for a final touch and goodbye to his pregnant wife. Behind every grand leap into the cosmos, is an extraordinary sacrifice made right here at home. #SpaceX #NASA #Crew13 #CSA #JoshuaKutryk 📷 Credit: Trevor Hicks for @TheLaunchPadX

He got it from his mama. Bear 89, aka Backpack, is the 2026 Fat Bear Week champ. Turns out hefty runs in the family. His mom, Holly the Duchess of Density, won in 2019. She carried him on her back as a cub and helped him survive a serious leg injury. Now her little Backpack has a crown of his own. 👑

I can assure you we have already been working on revisions to the planetary protection policies to bring them back in line with the common-sense principles originally established by COSPAR in the early days of planetary exploration and later reflected in Article IX of the Outer Space Treaty. We are needlessly adding extreme cost and time to robotic missions to Mars when the overarching goal is to send astronauts there as quickly and safely as possible.

.@NASA's @SpaceX Crew-13 members departed @NASAJohnson Space Center and arrived at @NASAKennedy Space Center on Saturday. The quartet is counting down to a launch aboard Dragon to the International Space Station on Thursday, Oct. 1.
This morning, the next crew destined for the International @Space_Station departed Houston -- until next year. Members of NASA's SpaceX Crew-13 -- NASA astronauts Jessica Watkins and Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk, and Roscosmos cosmonaut Sergey Teteryatnikov -- boarded NASA's T-38 aircraft for their flights to @NASAKennedy Space Center, where they're set to launch on October 1.

“I would not be surprised if we start seeing the first human missions to Mars in the 2030s.” Pioneer Labs CEO @erika_alden_d, whose team is engineering five organisms designed to help create livable areas on Mars, lays out her timeline for the Red Planet: "There’s a launch window in 2028… It would be really awesome to also have a search for life and a test that we can grow a first Earth organism.” “There’s another launch window early 2031, and that’s the one where maybe we could actually go there and demonstrate something.” "I’d be shocked if SpaceX doesn’t try to get to Mars in 2028, but I think they might succeed in 2031.”

In Houston at the Off World conference today, NASA’s Jared Isaacman said there would be an “Artemis acceleration” event to discuss plans to bring forward the Artemis IV lunar landing in “early October.”

Four crew members from three space agencies will launch to the International Space Station no earlier than spring 2027 for a long-duration science expedition as part of @NASA’s @SpaceX Crew-14 mission. More... go.nasa.gov/4hcZ1um

5 years ago today I went into orbit and life has never been the same! I’m so grateful I was chosen to be part of Inspiration4, the world’s first all-civilian orbital mission. And I’m most proud of the fact that our mission raised $250 million for childhood cancer research and treatment, a cause personal to me as I am a childhood cancer survivor. Will forever use my platform to spread my message of hope, that what you’ve been through doesn’t have to limit where you go

Pilots and Flight Attendants have highest cancer risk. Working decades above most of the atmosphere exposes them to cosmic radiation. Study ran 2000 to 2024, across 12.7 million decedents spanning 503 occupations. Living in space/on the Moon will be worse, no doubt. details: hms.harvard.edu/news/pilots-… @harvardmed @UQ_News

No aim too high. No journey too far. No terrain too challenging. We’re going back to the Moon. This time, to stay.

This is how we do science on the @Space_Station. In this demonstration, we have one person operating the ultrasound and the other person operating the controls. A remote guider and a team of doctors make sure that we’re getting the right images and also analyzing the images immediately in case we need to follow up. Scientists and physicians are concerned that microgravity changes the normal flow of blood and could predispose astronauts to blood clots.

I love this photo from the Artemis II archive The blurry hand of someone who has travelled further from Earth than anyone in history
The sci-future I dreamed about as a kid is right here at our doorstep Did you know you can request the raw photos from the Artemis II mission? There is a lot of information hidden in the RAWs that isn't visible in the jpgs. Check the next post in this thread for the raw

Spaceflight can disrupt astronaut immunity, including sustained downregulation of Major Histocompatibility Complex (MHC) class I genes. 🚀 go.nature.com/459vk6E In this perspective, @WeillCornell scientists from @mason_lab discuss the long-term risks associated with astronaut MHC class I suppression and outline therapeutic approaches with broader relevance to related health challenges on Earth. 🌍 #OpenAccess in @CommsBio. 🔓

Day 111, orbit 1722 — In this timelapse, I’m working on an experiment called DNA Therapeutics in the Life Science Glovebox located in the Kibo module. I’m handling blood stem cell samples as part of research exploring the idea of producing large amounts of clinical grade stem cells in space. The goal is to improve their quality, which could help advance treatments for blood disorders and cancer. Go science, and go cancer research! 🎥 @esa / @NASA #εpsilon • @esaspaceflight • @Space_Station • @NASAJohnson • @NASA_Marshall • @UConn  • @Axiom_Space

The more you learn about the insane amount of Apollo era engineers and astronauts that are still alive the more you become convinced they’re still here through sheer will to see another human land on the moon.
