International Space Station: Seven More Years

Image
Nations and organizations running the International Space Station agreed to keep supporting it until 2030. That's what I'll be talking about this week. Along with why the ISS won't last forever, plans for either ditching it in the South Pacific or starting an orbiting salvage yard, commercial space stations and something my oldest daughter and I thought of.

Commercial Space Services and Changing Times

This week I’ll talk about the SpaceX Starship and ispace test flights. Whether or not they were successful depends on who’s talking. I’ll also look at the usual hand-wringing over threats to the status quo.

Single Stage to Orbit, Eventually

Image
A tip of the hat to Anthony Stevens, whose recent op-ed started me thinking about this week's topics. " NoMoNASA " Anthony Stevens, Anthony Stevens' Weblog (November 25, 2022) I'll be talking about ideas that didn't work out, or haven't yet; three cool single-stage-to-orbit vehicles, including one that flew; and, finally, looking back and ahead. Or, rather, the other way around. Plus, I've included short videos showing Skylon, the VentureStar, and a test flight of the McDonnell Douglas DC-X Delta Clipper prototype.

Notre-Dame, Paris: History, Two Cults and a Fire

Image
The Notre Dame Cathedral in Paris has survived Louis XIV-style redecorating, the French Revolution, Napoleon and 19th-century remodeling. I'm pretty sure it will survive repair and reconstruction, following the April 16, 2021, fire. Notre-Dame de Paris is Burning (From Getty Images, via BBC News, used w/o permission.) Somewhere between 6:50 p.m., Paris time, and 7:18 p.m., April 15, 2019, something caught fire under the roof of Notre-Dame de Paris.... More at A Catholic Citizen in America .

Florida Indoor Fish Farm: An Aquaculture Alternative

Image
A few groceries have been offering delicacies like elk steaks for decades, at least. But the odds are that hunters aren't supplying your grocery's meat department with wild game. That's not surprising, or shouldn't be. I'll be talking about an indoor Florida fish farm, wild rasberries, chickens, and why genetically modified foods don't fill me with fear and foreboding.

BEAM Prototype Habitat, Bigelow's Plans

Image
The BEAM Bigelow Aerospace habitat module, will be launched toward the International Space Station (ISS) today: if all goes well. BEAM is packed in the Dragon spacecraft's pressurized section. This cargo run also carries supplies for the ISS crew, and for several dozen of the roughly 250 experiments planned for Expeditions 47 and 48. ( SpaceX press kit ) After getting attached to the ISS and inflated, BEAM will mostly just sit there for at least two years: empty except when someone in the ISS takes samples and swaps out radiation sensors. I think that's a good idea, since BEAM is testing technology for Bigelow Aerospace rental properties in low Earth orbit. More at A Catholic Citizen in America .

Luxembourg and Asteroid Mining

Image
Stories like " Rip Foster Rides the Gray Planet " and " Red Dwarf 's" Dave Lister singing "...Lived an old plutonium miner / And his daughter Clementine..." probably didn't help make asteroid mining seem like a serious idea. Then there's the 1966 Outer Space Treaty treaty: a tribute to the high ideals, and international politics, of the '60s. The idea was that anything we find outside Earth's atmosphere would belong to everyone. Nifty idea, not entirely wrong, and I'll get back to that. More at A Catholic Citizen in America .

Barsoom Development Ltd.

The Curiosity Mars Rover sent a 'postcard' from Mars, a 360-degree view of dunes and a mountain in Gale Crater.... ...As usual, I'll ramble on about science, technology, and being human before getting to the interesting stuff: assuming that you think a robotic selfie from Mars is interesting. Not-entirely-as-usual, I wasn't finished rambling when I started the 'postcard' stuff, so this post has an afterword. I've done that before.... More at A Catholic Citizen in America .

Beaver Cleaver and the Common Good

Image
I grew up in the 'good old days,' when many Americans enjoyed the seemingly-secure middle class lives of the Cleavers and Andersons . Some parents, mine included, remembered that there's more to life than wealth: so I never considered running away to a commune . But I understood why some folks my age, and a bit older, decided that buying stuff you don't need with money you don't have to impress people you don't like — made no sense at all.... ...I didn't have the horror that some older folks had for places like Drop City . It seemed to me that 'those crazy kids,' with their 'un-American' talk about peace, love, and brotherhood, had decided to take at least some of my Lord's values seriously....

Climate Change, Science, and the Vatican

Image
The 'Vatican science academy' is in the news again: this time because they've said we should use our brains. The topic was climate change, which tends to stir up sound and fury more than rational discourse. Meanwhile, one scientist implied a link between our "carbon dioxide crisis" and a lot of dead critters, some 201,000,000 years back. More to the point, I think, the team he was on has added a few more pieces to the puzzle of what caused the Triassic-Jurassic extinction event. More at A Catholic Citizen in America .

Ebola: Scary, and Beatable

Image
This year's Ebola outbreak has killed thousand of folks in West Africa: and one in the United States. By any reasonable standard, it's a very serious health problem.... ...As I've said before, being healthy is okay. ( June 13, 2014 ) Not being healthy is okay, too: but I'm expected to take care of my health: within reason.... More at A Catholic Citizen in America .

Lowering Costs on the Earth-to-Orbit Run, Preparing for Incoming Asteroids

Image
Getting scared silly by the latest doomsday prediction is silly. So is ignoring real threats. (Copyright M. Ahmetvaleev, via NASA News, used w/o permission.) The Chelyabinsk meteor didn't kill anyone. Only 1,100 or so folks needed medical treatment: for injuries ranging from cuts and bruises to a broken spine. Next time, we may not get off so lightly. Now is a very good time to start getting ready for an incoming asteroid.... ...Looking Ahead (Reaction Engines Limited/Terra Novus, via Wikimedia Commons, used w/o permission.) (Reaction Engines Limited's Skylon spaceplane.) Apart from Space Shuttle fleet, now out of service, and recoverable capsules like Space-X's Dragon, launch vehicles are still a single-use technology. That makes getting into space very expensive. A decade from now, we'll probably see shipping rates go down: dramatically, I suspect. Reaction Engines Limited's Skylon is scheduled for a test flight to the International Space Stati
