From the article: "The team's calculations indicate that young Jupiter had a radius nearly twice its current size, with a volume large enough to hold more than 2,000 Earths. In the present day, the planet's volume can fit 1,321 Earths" There's a glaring arithmetical error here. If as stated the...

The article says "Time on the moon passes about 58.7 microseconds faster than on Earth". Over what time interval is it 58.7 microseconds faster, over a minute, an hour, 24 hours? Poorly written article.

The article says "if this budget is enacted — a big if, as it must be approved by Congress — some big-ticket NASA programs will get the axe. Among them are Mars sample return, a joint effort with the European Space Agency to get material collected by NASA's Perseverance rover back to Earth, and...

Interview with Starliner astronauts reveal that the situation was more precarious than many realised. The failure of so many thrusters violated the mission's flight rules. In such an instance, they were supposed to turn around and come back to Earth. But what if it was not safe to come home...

Whilst I think nobody would quibble with the idea that the US has been and should continue to be a leader in Space exploration the acting NASA administrator's choice to use the words "dominate" and "domination" with their military related connotations rather than "lead" and "leadership" does...

One thing about the proposed Artemis mission architecture that really seems astonishing is that it requires no less than 15 fueling launches! OK I know the system has a much larger Human Landing System than the old Apollo LM and that they are targetting the lunar south pole region with a maximum...

To me the most amazing thing about this story is that there is a Goddess of door hinges! :tearsofjoy:

Recent article on space.com https://www.space.com/19824-clyde-tombaugh.html The article says "The telescope at the observatory was equipped with a camera that would take two photographs of the sky on different days. A device known as a blink compactor rapidly flipped back and forth between the...

Beat me to it. Apart from anything else a true interstellar ship would need to be self sufficient, both in energy and necessary resources (food, water etc). The ISS gets its energy from solar panels (not much use in interstellar space!) and it relies on frequent cargo deliveries of food from Earth.

Good points. Of course the Starships landing on the Moon will still have a substantial amount of propellants as they need to lift off from the surface again to rendezvous with the lunar gateway.

My understanding is that in the short term SpaceX's development tests intend to catch starship with the chopsticks in a similar fashion to the super heavy booster catch already demonstrated. This removes the weight of the landing legs, so optimising the load capacity of starships that return...

The signal to noise ratio on this thread is very low..... :tearsofjoy:

Bowers3934, no offence was intended, I just wasn't sure if you had understood my point about the arbitrary nature of the sampling and the resultant recorded values. In relation to your "YES" response does that reflect your belief that 1800 years ago aliens sent a message to Earth and they...

As the signal originated 1800 light years away it originated 1800 years ago. The graph of the signal you posted shows the sample rate as every 12 seconds. ( 5 sampling intervals between 0 and 60 seconds on the graph, 5 sampling intervals between 60 seconds and 120 seconds, 5 sampling intervals...

A Light Year (LY) is a unit of distance, not time. Also I note you haven't commented on my post that pointed out that the digital sampling timing that resulted in the 6EQUJ5 sequence was purely arbitrary and a different sampling interval or start time would have resulted in a completely...
