PARIS – The largest commercial satellite ever built – the massive TerreStar-1 – launched into space on Wednesday, riding a European-built rocket into orbit.
Can we live on Titan?
Habitability. Robert Zubrin has pointed out that Titan possesses an abundance of all the elements necessary to support life, saying “In certain ways, Titan is the most hospitable extraterrestrial world within our solar system for human colonization.” The atmosphere contains plentiful nitrogen and methane.
How big is Ganymede vs Earth?
Ganymede is the largest and most massive moon in the Solar System. Its diameter of 5,268 km is 0.41 times that of Earth, 0.77 times that of Mars, 1.02 times that of Saturn’s Titan (Solar System’s second largest moon), 1.08 times Mercury’s, 1.09 times Callisto’s, 1.45 times Io’s and 1.51 times the Moon’s.
Which is bigger Titan or earth?
Titan is the largest of Saturn’s 62 moons and the second largest moon in the solar system after Jupiter’s Ganymede. … The radius of Titan is about 1,600 miles making it smaller than half the size of Earth (3,963 miles) but larger than the Earth’s moon (1,079.6 miles).
Is there gold on the moon?
There is water on the moon … along with a long list of other compounds, including, mercury, gold and silver. … Turns out the moon not only has water, but it’s wetter than some places on earth, such as the Sahara desert.
Is there gold in space?
As it turns out, there’s a giant asteroid that contains enough gold and other metals to make everyone on Earth a multibillionaire. And NASA uses gold to protect spacecraft from radiation. With all the gold out in space, extraterrestrial mining is a real possibility.
Can we breathe on Ganymede?
In 1996, astronomers using the Hubble Space Telescope found evidence of a thin oxygen atmosphere. However, it is too thin to support life as we know it; it is unlikely that any living organisms inhabit Ganymede.
Is Ganymede a God?

Does Ganymede have oxygen?
Atmosphere: Similar to Europa, Ganymede has a tenuous oxygen atmosphere. … Additional evidence of the oxygen atmosphere comes from the detection of various gases trapped in the ice on Ganymede.
Does Titan have oxygen?
Titan’s atmosphere is much colder, however, having a temperature at the surface of 94 K (−290 °F, −179 °C), and it contains no free oxygen.
Are there any habitable planets?
A 2015 review concluded that the exoplanets Kepler-62f, Kepler-186f and Kepler-442b were likely the best candidates for being potentially habitable. These are at a distance of 1,200, 490 and 1,120 light-years away, respectively.
Is Titan smaller than Mars?
Saturn’s Titan has an atmosphere denser than Earth’s, yet Titan is a smaller body than Mars. … Titan’s surface temperature is also quite low, about 90 K. Therefore, the mass fractions of substances that can become atmospheric constituents are much larger on Titan than on Earth.
Who owns the moon?
The Outer Space Treaty means therefore that – no matter whose national flags are planted on the lunar surface – no nation can ‘own’ the Moon. As of 2019, 109 nations are bound by the Treaty, and another 23 have signed the agreement but have yet to be officially recognised.
Does NASA use gold?
Gold is also used by NASA in the construction of spacesuits. Because of its excellent ability to reflect infrared light while letting in visible light, astronauts’ visors have a thin layer of gold on them to protect their eyes from unfiltered sunlight.
Is there oil on the moon?
Instead of water, liquid hydrocarbons in the form of methane and ethane are present on the moon’s surface, and tholins probably make up its dunes. … Several hundred lakes and seas have been observed, with each of several dozen estimated to contain more hydrocarbon liquid than Earth’s oil and gas reserves.
