The article is limited to biological life. However, it might be that our species has a future (a very far future) wherein we migrate from a biological existence to an electronic one, at which point we could fashion our bodies into a form ideal for life in space if we so chose.

It seems to me that the FAA is fining SpaceX for the FAA's failure to regulate on a timely basis, thus putting their 'monkey' on the back of SpaceX where it doesn't belong. Except for acting before the FAA stamp of approval was made, the FAA has not claimed that SpaceX's actions did not...

I noticed this article included the following advert: You can build your own Boeing Starliner space capsule with this Metal Earth Boeing CST-100 Starliner 3D Metal Model Kit. This kit is particularly realistic since the control reaction jets on the model don't work either, just like the...

I was actually relieved when I heard the news. Even at the point where Starship can make a trip around the moon, I would consider that it is still very early days for the design, making a trip with it by civilians very risky. Maezawa, cutting out like this, might just have saved the lives of all...

The article says nothings about these exclusive license agreements costing the companies involved any fees. Why should a select few receive the free largess of public investment? Why should NASA not be required to license the alloy's formula for a market-sensitive license fee to any US...

There is a typo in this article. The mass of Sag A* is about 4.3 MILLION times that of the sun.

I wonder if NASA has ever considered "selling" for a dollar an operational satellite it doesn’t have the operating budget to maintain in terms of program resources. The “purchasing” space agency would inherit a working satellite with some time remaining on its ‘clock’ along with the obligation...

Well, if the politics of science can't be discussed, then Space.com should be following its own rules and not post political-issue stories like budget cancellations. Personally, I don't see the difficulty with recognizing and discussing the issue of science funding since it is very relevant...

A few points for your consideration: 1) For those interested, Everyday Astronaut does a good more in-depth review of rocket pollution issues at the following link: View: https://www.youtube.com/watch?v=C4VHfmiwuv4 2) I believe Musk plans to develop a non-fossil-fuel Methane source...

Thanks for your insight into the rules and regs under which the FAA operates and which they use to define a 'mishap'. However, I didn't find that any of those criteria applied to the 3rd test, and even the 2nd test, including the 3 you noted as applicable. For example: 1) Unplanned permanent...

These outbursts, as well as eruptions of scorching-hot plasma known as coronal mass ejections (CMES), can be incredibly destructive to planets orbiting red dwarfs, stripping their atmospheres and emitting enough radiation to boil away liquid water While these flares may be strong enough to...

Hi PWB, thanks for your thoughtful response. As I reflect from my 'arm-chair' on the concern you've expressed, I wonder if the bias you detect might be related to the way in which science journalism operates. As I understand it, journalists see some new study coming out, and write up a...

The whole issue of antarctic ice levels and its relationship to Climate Change and global sea levels is really quite complex and beyond the expertise of arm-chair experts, including myself. You're an arm-chair expert if you hold strong opinions on the subject but don't have extensive experience...

This is a science-based web-site, and so the article is written to an audience that is knowledgeable enough to know that long-term historic ice levels in the Antarctic and Arctic since the peak of last ice age about 21,000 years ago are known to be much higher than modern levels. No hysteria...
