NASA has selected the four astronauts that will travel to the Moon during the upcoming Artemis 2 mission, which will be humanity’s first crewed return to the Moon in more than 50 years.

The four astronauts are Reid Wiseman, Victor Glover, and Christina Koch of NASA, and Jeremy Hansen of the Canadian Space Agency.

“The Artemis 2 crew represents thousands of people working tirelessly to bring us to the stars,” said NASA Administrator Bill Nelson before announcing the crew during a live event broadcast on NASA TV. “This is their crew. This is our crew. This is humanity’s crew.”

The Way It's Supposed To Be...

ALMATY, March 30 (Reuters) - A U.S. astronaut and two Russian cosmonauts safely landed in Kazakhstan on Wednesday after leaving the International Space Station aboard the same capsule despite heightened antagonism between Moscow and Washington over the conflict in Ukraine.

The flight -- carrying NASA's Mark Vande Hei and Russians Anton Shkaplerov and Pyotr Dubrov back to Earth -- had been closely watched to determine whether escalating strife had spilled over into longtime cooperation in space between the two former Cold War adversaries.

Russian space agency Roscosmos broadcast footage of the landing from the Kazakh steppe and said a group of technical and medical specialists had been dispatched to help the astronauts out of the capsule.

"The crew is feeling good after landing, according to rescuers," Roscosmos chief Dmitry Rogozin wrote on Telegram messenger.

Vande Hei, who had completed his second ISS mission, logged a U.S. space-endurance record of 355 consecutive days in orbit, surpassing the previous 340-day record set by astronaut Scott Kelly in 2016, according to NASA.

ISAAC...

NASA’s Integrated System for Autonomous and Adaptive Caretaking, or ISAAC, is advancing new technology for robots to take care of spacecraft. Researchers recently demonstrated the tech aboard the International Space Station using Astrobee, NASA’s free-flying robotic assistants.

In April 2021, Bumble, one of the free-flying Astrobee robots aboard the International Space Station, was put to the test to investigate a simulated anomaly. In the simulation, the station’s life support systems detected a high concentration of carbon dioxide. A similar situation, in reality, could be very dangerous for the seven people who are living and working aboard the microgravity laboratory.

 

During the test, the small, cube-shaped robot adeptly navigated the station to find the location designated as a "vent" used for cabin air circulation and used computer vision to automatically detect the foreign object blocking the vent – an "astronaut sock," represented by a printed image of a sock. Then, Bumble called for help to clear the blockage. For its next test, Bumble completed a survey of Bay 6 of the space station’s Japanese Exploration Module, building a high-resolution multi-sensor 3D map. During this journey, Bumble found itself bumping into and untangling itself from stray cables, and coping with simulated space-to-ground communication interruptions. It ultimately persevered and completed its mission objectives, with a little timely help from ground operators.

 

This simulated fault scenario marked the end of the first phase of testing for software designed to enable autonomous operations of a spacecraft’s operating and robotic systems. The software’s name is ISAAC – the Integrated System for Autonomous and Adaptive Caretaking.

 

"ISAAC is far more than just a management tool for our robotics and spacecraft systems," said Trey Smith, the project manager for ISAAC at NASA’s Ames Research Center in California's Silicon Valley. "Our long-term vision is that it can transform a spacecraft into an autonomous robotic system itself."

 

NASA's future Artemis missions to the Moon and beyond will take humans farther than they ever have before – and a host of robotic and mechanical systems will go with them. On the space station, much closer to home, astronauts have been able to stay full time, surpassing 20 years of continuous human presence – something that won’t be possible in deep space for some time. How can future spacecraft operate smoothly without that consistent human touch? ISAAC aims to deliver technologies to enable remote and autonomous caretaking during long periods of time when the astronauts are not aboard to perform maintenance, logistics management, and utilization tasks, as well as when communicating with ground controllers is limited or simply unavailable.

A Voyage In Her Lifetime...

Light Sails were first mentioned in the year 1610 in a letter by astronomer Johannes Kepler to his friend, Galileo Galilei. “With ships or sails built for heavenly winds, some will venture into that great vastness.” In his character of Benjamin Sisko on Star Trek: Deep Space Nine, Avery Brooks used his Starfleet engineering prowess deciphering ancient text to recreate an ancient Bajoran solar sail in the episode "Explorers." The possibilities have vacillated between science and fiction ever since.

 

I've enjoyed reading the speculation by Avi Loeb, Chair of Harvard University's Department of Astronomy on the Oumuamua object in Extraterrestrial. I've also enjoyed the healthy counter debate, as that's how ideas in science are refined before they become laws, doctrine, or accepted universal theorems.

 

On the "billionaire space race": Eli Musk started it with his SpaceX rocket system. It would be nice in current geopolitical tensions not to rely so much on Russian Soyuz capsules to get to the ISS. Brian Branson and Jeff Bezos have probably opened up space tourism, but in the foreseeable near-future and exorbitant price tag, it will probably be a dalliance of the wealthy. Desktop computers used to cost between $2,000 - 3,000, cell phones irradiating Gordon Gekko's skull in the movie "Wall Street" used to be the size of Canada. Even the fictional Zefram Cochrane needed a financier, Micah Brack, to get Warp One going. Whether that leads to a utopia of limitless energy, the end to poverty, money, life extension, and eliminating inequality is yet to be seen.

 

The article title, Breakthrough Starshot: A voyage to the stars within our lifetimes, Astronomy Magazine, takes into account the bane of our spacefaring existence: mass, quite literally a "drag," and cannot be compensated for by technobabble "inertia dampeners" or artificial gravity. We are currently accelerating at 9.8 meters per square second to the Earth's center, but we're used to it after living here a while. Twenty percent of the speed of light would get a nano solar sail craft propelled by a high-energy laser to Alpha Centauri in twenty years but would turn human passengers (if any were that small) into DNA goo against the bulkhead. Starshot launching in 2060 means my granddaughter will be forty-one, her parents might be grandparents, and I would have to be a spry ninety-eight to witness it. "Our lifetimes" must be humankind, that is if we haven't overextended our resources to make the endeavor fruitless. From the end of the article:

 

But as award-winning Cosmos writer and producer Ann Druyan, a member of the Breakthrough Starshot advisory board, said during a 2016 press conference announcing the initiative: “Science thinks in timescales of billions of years. And yet, we live in a society that only thinks in terms of, generally, the balance sheet of the next quarter or the next election. … So, this kind of thinking that looks at a horizon that’s 35 years away — possibly 20, possibly 50 — is exactly what’s called for now, because it’s this kind of multigenerational enterprise that nets us such great results.”

 

Godspeed, "Little Bit."

Happy Veteran's Day.

Expedition 1 and Crew-1. These historic International Space Station missions lifting off 20 years apart share the same goals: advancing humanity by using the space station to learn how to explore farther than ever before, while also conducting research and technology demonstrations benefiting life back on Earth.

Crew-1 made up of NASA astronauts Shannon Walker, Victor Glover, and Mike Hopkins, and Japan Aerospace Exploration Agency (JAXA) astronaut Soichi Noguchi, continues the legacy of two decades of living and working in low-Earth orbit by becoming space scientists for the next six months.

Not only will the Crew-1 astronauts and fellow Expedition 64 NASA astronaut Kate Rubins conduct hundreds of microgravity studies during their mission, but they also deliver new science hardware and experiments carried to space with them inside Crew Dragon.

Check out some of the research flying to the space station alongside Crew-1, and scientific investigations the astronauts will work on during their stay aboard the orbiting laboratory.
