Given that 2022 was a busy year, I thought I would highlight the top astronomy stories on the site – the good and the bad covering space missions to TV shows. Unlike other websites, I waited until the new year to create the list just in case we were visited by extraterrestrials. In this way, we now have a full catalog of the 2022 happenings.
Here is the list in no particular order other than science first, politics and commercial space second, and entertainment third.
Much has been discussed about the test dummies used on the Orion capsule during the recent Artemis I mission. And stories abound about the snoopy doll (show below) being the “zero-gravity” indicator on the Orion. But have you heard about the four Danish passengers on the capsule?
The Danish company Lego had four toy astronauts on the Orion capsule as well – Kate, Kyle, Julia, and Sebastian. It’s part of an educational series for children. NASA and Lego have been educational partners for a while now.
Are these the first toys in Space? Absolutely not. For instance, space shuttle astronauts have brought a teddy bear and Star Wars light saber into into orbit, among other things. And last year a SpaceX capsule sent to the International Space Station contained a stuffed penguin, which was also used as a “zeroed-gravity” indicator.
I support any endeavors to excite children about the space program. Soon enough we will see what else the Artemis program might have in store for children as well as the kids at heart.

On a recent episode of the Clear + Vivid podcast, Alan Alda interviewed NASA engineer Les Johnson about his efforts to develop a solar sail that can take us to the stars. He is the Principal Investigator for the NEA Scout, which was launched into space during the Artemis I mission and is now heading towards a near-Earth asteroid via solar sails (see above).
During the interview, Mr. Johnson discussed the NEA Scout as well as his hopes for future human travel to the stars using solar sails, noting that while slow, the sails can outperform modern rocket engines in the long-run. He also pointed out that a solar sail may be able to get us to Proxima Centauri, the closest neighboring star, in hundreds of years versus the 70,000 years it will take the Voyager spacecraft to travel that same distance. I like how he puts such a mission in perspective, pointing out it took hundreds of years to build some of the great cathedrals.
Messrs. Alda and Johnson also discussed the ethics of space travel considering astronauts will be spending generations in space with many humans never seeing either the Earth or the destination in their lifetime. Mr. Johnson said space lasers may be another option for interstellar travel at some point in the future, reducing the travel time to Proxima Centauri to 40-50 years. Given the time spans, he said it may make sense to initially send robots into space first.
Finally, the podcast covered missions closer to Earth, such as mining asteroids for water and minerals, as well as 3D printing to create what we need in space. It sounded a lot like the situation in find in the science fiction TV series The Expanse.
Overall, it was a great conversation worth a few minutes of your day. Check it out.
Extra: Mr. Johnson is also the author of several books, including the co-authored Saving Proxima. Here is a quick summary of that tale:
2072. At the lunar farside radio observatory, an old-school radio broadcast is detected, similar to those broadcast on Earth in the 1940s, but in an unknown language, coming from an impossible source—Proxima Centauri. While the nations of Earth debate making first contact, they learn that the Proximans are facing an extinction-level disaster, forcing a decision: will Earth send a ship on a multiyear trip to render aid?
Interstellar travel is not easy, and by traveling at the speeds required to arrive before disaster strikes at Proxima, humans will learn firsthand the time-dilating effects of Einstein’s Special Relativity and be forced to ponder ultimate questions: What does it mean to be human? What will it take to share the stars with another form of life? What if I return younger than my own children? The answers are far from academic, for they may determine the fate of not one, but two, civilizations.

On this day in 1972, Apollo 17 commander Eugene Cernan was the last human to be on the Moon. He was the eleventh human to ever step on the Moon.
Here is the full crew of Apollo 17:
Eugene A. Cernan, Commander
Harrison H. Schmitt, Lunar Module Pilot
Ronald E. Evans, Command Module Pilot
Mr. Cernan, who passed away in 2017, was also part of the Apollo 10 mission that orbited the moon without landing (similar to the upcoming Artemis II mission).
With the successful orbit of the Orion spacecraft around the Moon this month, let’s hope the 50 year dryspell is finally over and the United States can again be the nation putting humans back on the lunar surface. Of course, we will be followed by others, including the Chinese. Yet it’s important the first space-faring nation get back in the game and restart the human exploration of the Moon, and then Mars soon thereafter.

The Orion has landed, or splashed down to be more accurate. The Artemis I mission had a successful finish with the Orion capsule parachuting down into the Pacific at 12:40 p.m. EST today. At the time of this posting, the capsule was still afloat in the water while awaiting a review by engineers before being taken aboard the USS Portland.
