Pros: competition with Starlink, more Internet connectivity for the world. Cons: this + Starlink + OneWeb make wide-field Earth-based astronomy much harder, making it less likely that we'll notice new astronomic phenomena or inbound ci

I was just thinking how GPT-3 could be that novel's method of generating so much noise as to inoculate everyone against astroturfing.

Correct, along with a bunch of other deep space craft. See my comment down thread: https://news.ycombinator.com/item?id=23954547

I fell down a Wikipedia Hole deep into the history of nuclear reactors in space. There are many radioisotope heater units (RHUs) in space, such as those used by Chang'e 4 to survive the cold lunar nights, and radioisotope thermoelectri

GPT3 isn’t generally able to cite sources and tends to confabulate realistic but incorrect answers to questions. It’s great as an ideation tool, much less so as a search engine.

We're finding exoplanets at an incredible rate. See NASA's Exoplanet Archive ( https://exoplanetarchive.ipac.caltech.edu/ ) for the current 4164 known exoplanets. Related: The Very Large Telescope (VLT) in Chile jus

Good writeup! In general, the direction in modern aerospace is to use COTS (commercial off-the-shelf) parts with redundancy and failback for radiation hardening. If you’re into this sort of thing, I co-write a weekly newsletter about the sp

Yes, there were likely other costs, but from NASA's perspective, their costs were way lower. For example, for their first investment of $396M in commercial cargo deliveries to the ISS with SpaceX, they got the development of the Cargo

This is a huge success for NASA's Commercial Crew Program. Both the total development costs ($1.7B and $2.8B for Crew Dragon and Starliner, respectively) and the per-seat costs ($60-67M and $91-99M) have outperformed all other NASA cre
