A spacecraft selfie, taken at a comet. This is Rosetta, just 16 km from comet 67P and 472 million km from home. It was the last shot from Philae's camera before Philae dropped off to try the first ever

I've been having fun with Grok Bot and its Build bot. Last night I described a Starship lander game. Today it's landing on the Moon, crashing on Mars, then nailing it on the second try. 🚀 No game engine,

Building 20 Starships a week with rapid reuse scales past 10,000 launches a year. That's ~27 to 32 flights a day, lifting 1.5M to 2.0M tonnes to orbit. The real puzzle is where all that payload would come

Flight 15 could be the first dual catch: booster back to the tower, then the ship caught by the same tower later in the mission. Here's how I picture the sequence, time-lapsed. The booster gets moved off

Building 20 Starships a week with rapid reuse scales past 10,000 launches a year. Here is my best-guess breakdown of where all those flights go. The full article with the numbers is on my PeakD blog

I've been thinking about... Mars... would I really go if the seat was offered? It seems like it would be a great adventure, yet it's going to be really hard to start with. Even with Optimus androids doing

What a contrast. For the Artemis moon landing, two astronauts will go to the surface in Starship, while two remain in the Orion capsule in LL0 during the mission. Two land and live in total luxury in the

Classic Cosmos Our nearest big galaxy, the way the south sees it. From the Southern Hemisphere, Andromeda never climbs high. In spring it only just clears the northern horizon. That's exactly what Lucy

So the question of the day is: On Artemis IV, what happens to the Starship HLS once the crew transfers back to Orion at step 15? NASA's chart stops tracking it after Orion undocks, and with no heat shield

One Time for Every World - How I keep time across Earth and Mars, and the date I'm counting down to If you've seen "Today is CSD ..." at the top of my posts and wondered what the number means,

Do I see 6, 7 or 8 new Starship nose cones being built at the same time? This image from today's NASA update.

How to get replaced to your own advantage. Now is the time to buy a long-haul truck - and a humanoid. Remember when I said AI + humanoid robots will eventually replace every job? This is one of those jobs…

Where is Starship 40 today 5 Oct 2026? Ship 40 remains aboard the Boskalis Forte. She's left the South Atlantic behind. Latest AIS puts her in the Caribbean Sea, roughly 20°N 83°W, still pushing toward

While there is a lot of discussion about what SpaceX Starship is doing on the next test flight, there still is not enough about how radically Starship will change the face of space once it is fully

Lots of discussion about Starship landing backup options. There is one solution - Dragon.

I was watching Ship 41 come in on Flight 14. In the last part of the belly flop, just before the flip and burn, it was dropping at about 100 metres a second. That’s roughly 360 km/h, still falling sideways.

So the question of the day is: If a Moon or Mars colony declares independence, can someone on Earth become a citizen without ever going? Passport, vote, tax. No longer governed from Earth. All from a couch

Will we only trust Starship if it lands like a plane of the Space Shuttle? That is the question people keep asking when they watch a belly-flop flip into a late Raptor relight. Certification can clear

A laboratory on Mars beats MSR. Surely? The prize is not a box of rocks in Houston. The prize is answers. Age, chemistry, organics, context, and whether Mars ever held anything alive. Classic sample return

To Chicken on Mars, or not to Chicken? That is the question? Once people live in large rotating habitats around Earth and in settlements on Mars, and once those places grow serious amounts of food, then
