NASA astronaut Catherine Coleman plays a flute aboard the International Space Station in 2011.. Music in space is music played in or broadcast from a spacecraft in outer space. [1] [failed verification] The first ever song that was performed in space was a Ukrainian song “Watching the sky...” [2] (“Дивлюсь я на небо”) sung on 12 August 1962 by Pavlo Popovych, cosmonaut ...
Humans have achieved some mediated presence throughout the Solar System, but the most extensive presence has been in orbit around Earth. Humans reached outer space mediated in 1944 and have sustained mediated presence since 1958 , [a] as well as having reached space directly for the first time on 12 April 1961 (Yuri Gagarin) and continuously ...
In recent years, there has been an increase in research on the issue of how humans can survive and work in space for extended and possibly indefinite periods of time. This question requires input from the physical and biological sciences and has now become the greatest challenge (other than funding) facing human space exploration. A fundamental ...
Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
For a stable orbit the ratio between the moon's orbital period P s around its primary star P p must be < 1 ⁄ 9, e.g. if a planet takes 90 days to orbit its star, the maximum stable orbit for a moon of that planet is less than 10 days.
Astronaut Bill Anders, who orbited the moon aboard Apollo 8 in 1968, has died in a plane crash off the coast of Washington state. His photo 'Earthrise' captivated the world.
If a day takes years, the temperature differential between the day and night side will be pronounced, and problems similar to those noted with extreme orbital eccentricity will come to the fore. The planet also should rotate quickly enough so that a magnetic dynamo may be started in its iron core to produce a magnetic field.
