What f the Moon where at the distance the ISS is?


The Moon is at about 384000 km distance from Earth. That’s a pretty big distance and it tidaly locked with our planet so that it will alwyas show the same face to our planet and, because of this, the time it takes to revolve around itself is equal to the time it takez to amke one turn around Eart.

If the Moon would be at the distance the IS is, which is about 340 km high, then the video from above would display how the Moon looks like just before it would be shredded to pieces. At that distance or even more, an object the size of the Moon would be shredded to pieces by Earth gravity. We would have quite a lot of rings because of this.

Yay. NASA is restarting supply to ISS. About time, guys! Video live NOW!

You can check now the status of the cargo which flies now to the ISS on NASA Ustream channel. The private company United Launch Alliance uses an Atlas V rocket to carry an Orbital ATK Cygnus commercial resupply spacecraft in order to get much needed cargo to the International Space Station (ISS) “following a pair of launch failures over the past year”.

It was about time that US started the reppluy mission. Until now only the Russians could send cargo up there and if they would have gone rogue, then ISS astronauts would’ve been in peril. It is always to have at least two choices when doing everything, because having two companies or states competing for the same thing will lead to better results.

Unfortunately NASA has had its funds slashed over the last decades and it struggles to make great progress with a tinier and tinier budget. Granted, they do have several hundred millions a year, but they would really need a 10 billion a year at least. Heck, I’d like to see a world in which countries like Romania can pay and fund NASA for at least 100 million a year in order to allow it to continue doing great things.

Go NASA and United Launch Alliance 😀 Once again, the private space companies are a proof of why US is the greatest country of them all.

ISS time-lapse over Earth. Friday fun!


It’s been some time since I published a blog post with a time lapse video. Once again the ISS given us an amazing view over Earth and the full HD images bring us closer to it, at about 370 km altitude.

The astronauts living in there fly with about 70 km/s and circle the Earth every 90 minutes. They see a ton of great stuff in there. Amazing!

Study: bone density decreases in space


The decrease in the mineral density in the bones is caused by microgravity. When there is no more strain ont he bones to keep us up and keep us in one piece, then the bones start degrading as they will not be built back as they should under low gravity conditions.

The main cause, of all, is the fact that there is no more stress on the bones and thus the body does not allocate resources to strengthening them. The astronauts on ISS are, thus, exercising daily in order to keep the strain on the muscles and bones and keep them as healthy as possible.

Should we use micro-ogranisms to colonize Mars?

I’d say YES, do this. We do not know the full scale effects and also how these bacteria would mutate, but if we can use micro-organisms that would generate enough oxygen for us to live and would also generate organic materials that would help plants grow, then why not?

Better to have a bacteria planet than a dead planet. As long as we can also get some plants in there and bring oxygen in the air, that should be a good starting step.

In any case, colonization of Mars is hard because:
– Mars does not have a magnetic field – you are at the mercy of radiation form sun and beyond
– temperatures vary greatly and only on Ecuator you get 20 degrees Celsius
– air pressure is very low
– the air contains mostly carbon dioxide and no trace of Oxygen
– gravity is lower in there
– there is almost no liquid water
– the soil does not have enough nutrients for plants to grow in there

So, colonization of Mars is a tricky thing to do and it may take us hundreds of years to perfect it. I’d like to travel back and forth to Mars some day 😀

Underlapsed, dizzy as it gets. Amazing timelapse!


I have seen this first on Kuriositas, a website where you can see tons of animations and cool stuff from all over the web and the world. This time Underlapse has caught my attention because it is a timelapse of Earth, space and different locations with the images being turned upside down.

Not long after the film starts you’ll feel dizzy, so watch out to have something to grab on to, okay? 😀 Have fun!

ISS: Space Oddity sends us a warm message from the coldness of space

Commander Chris Hadfield created Space Odity on board the International Space Station and it is a revised version of David Bowie’s “Space Oddity”. ISS, a “city in a tin can”, is indeed a oddity, because normally humans wouldn’t reach that far away if it weren’t for the passion and drive that made us jump through technological leaps.

The song is great, the setup also and this ISS commander has talent.

“Can you hear me floating in a tin can…” Awesome!

Tour of ISS in three amazing videos

See the ISS like never before. Expedition 33 Commander Sunni Williams shows us a couple of modules and answers some of our questions regarding everyday life in there. Can it be called like that”everyday life? No way!

We will visit modules Harmony, Tranquility and Unity, then the Cupola (observation deck), training area and the Leonardo Permanent Multi-purpose Module. After this we get to see the oldest part of the ISS: the Russian modules. Those modules have stood up strongly in the fight against time and one of those modules is actually the command center of ISS. Glad to see that at least in regards to the ISS Russia and US are getting along.

Check these other videos too. Below is the Cupola and training module:

And here we see the Russian modules:

Enjoy space? I would 😀

Breathtaking ISS time lapse [Bonus: ESO offers prises]


Earth {ISS-Timelapse} – Rise from Joan is absolutely amazing. I was a bit disapointed at first with that overwhelming speed in the video, but then it got really interesting. Could not help it and needed to post it here.

This new time lapse of ISS reminds me why we need to go over any boundaries to get to the stars. You can do your own time lapse video with the pictures offfered freely by NASA here.

And while we’re as astronmy level here is the Bonus> ESO- Europe Southern Obervatory offers several prises, among them an iPAD and a journey to the VLT telescope in Paranal, Chile. For this you need to click the image below and then take part in the two competitions in there. What did you chose VLT to scout in the sky and what meesage have you tweeted to @ESO with the reason you want to go to Paranal? Enjoy!

:01 — Stars over southern United States
:08 — US west coast to Canada
:21 — Central Europe to the Middle East
:36 — Aurora Australis over the Indian Ocean
:54 — Storms over Africa
1:08 — Central United States
1:20 — Midwest United States
1:33 — United Kingdom to Baltic Sea
