SpaceX confirmed its plan to launch over 4000 internet satellites into space

May 6, 2017 1 comment

Elon Musk continues to surprise. Almost each month there is new big plan by one of his companies (tunnels under LA, new gigafactory etc) and now SpaceX confirmed plan to launch over 4000 satellites into space. There has been many news about this project in the past, but now it seems to be much more realistic. Recently SpaceX has asked US government to get permission to launch its own internet network from orbit.

If SpaceX follows through its plan, company will start to provide wide range of broadband and communication services for people all over the world. So far satellite internet is slow and expensive, but with this plan it might change. similar plans has already OneWeb company, but plan of Elon Musk seems most realistic – as SpaceX did already prove to have reusable space rockets. Company plans to launch and release satellites into orbit till the end of 2024.

Another subsurface ocean discovered in our solar system

October 6, 2016 Leave a comment

dioneWe knew already that two out of many Saturn´s moons hide oceans beneath their icy crusts. These already known are moons Titan and Enceladus. According to newest data from the Cassini spacecraft, there is subsurface ocean also below the crust of Saturn´s moon Dione.

The new study, published this week in Geophysical Research Letters, suggests an ocean exists on Dione as well. The researches say: “seen from within, Dione is very similar to its smaller but more famous neighbor Enceladus, whose south polar region spurts huge jets of water vapor into space. Dione seems to be quiet now, but its broken surface bears witness of a more tumultuous past”.

If researches are correct, Dione´s oceans has probably survived through the whole history of the moon. And thus offers a long-lived habitable zone for microbial life.

Distance between spacecraft and Pluto will be about 12,500 km.

As spacecraft is approaching Pluto it gives us more and more photos of Pluto and its largest moon Charon. Interesting time-lapse was made from Long Range Reconnaissance Imager camera aboard New Horizons taken between May 28 and June 25.

MESSENGER_mercuryMessenger is spacecraft that was launched by NASA in 2004 with aim to study Mercury. Among the most important objectives of its mission were to characterize the chemical composition of planet’s surface and to study planet’s geologic history. After 11 years of its mission spacecraft was running out of fuel and crashed into surface of the planet 8,750 miles per hour on Thursday.

Messenger’s mission is considered to be success with many new findings about planet named after Roman deity Mercury, the messenger to the gods. Read more:
