Earth's atmosphere photographed from the International Space Station.The orange and green line of airglow is at roughly the altitude of the Kármán line. [1]The Kármán line (or von Kármán line / v ɒ n ˈ k ɑːr m ɑː n /) [2] is a conventional definition of the edge of space; it is widely but not universally accepted.
Maximum Speed - 5,971 km/h. Maximum Altitude - 106,010 m. 80 cm diameter balloon towed on 30 m line to measure air density. First X-15 flight over 100 km (a height known as the Kármán line). This made Walker the first US civilian in space. [1] This was also the first spaceflight of a spaceplane in aviation history. First flight launched over ...
In practice, only 1:1 ratio (geosynchronous) and 1:2 ratios (semi-synchronous) are common. Geosynchronous orbit (GSO): An orbit around the Earth with a period equal to one sidereal day, which is Earth's average rotational period of 23 hours, 56 minutes, 4.091 seconds. For a nearly circular orbit, this implies an altitude of approximately 35,786 ...
In this case the lowest required delta-v, to reach 100 km altitude, is about 1.4 km/s. Moving slower, with less free-fall, would require more delta-v. [citation needed] Compare this with orbital spaceflights: a low Earth orbit (LEO), with an altitude of about 300 km, needs a speed around 7.7 km/s, requiring a delta-v of about 9.2 km/s.
Depth of the Challenger Deep in the Mariana Trench, the deepest-known point on Earth's surface 27 km Circumference of the Large Hadron Collider, as of May 2010 the largest and highest energy particle accelerator: 42.195 km Length of a marathon: 10 5: 100 km: 100 km The distance the IAU considers to be the limit to space, called the Karman line
[nb 1] Earth's orbital speed averages 29.78 km/s (19 mi/s; 107,208 km/h; 66,616 mph), which is fast enough to cover the planet's diameter in 7 minutes and the distance to the Moon in 4 hours. [3] The point towards which the Earth in its solar orbit is directed at any given instant is known as the "apex of the Earth's way". [4] [5]
Song of Songs 1 (abbreviated [where?] as Song 1) is the first chapter of the "Song of Songs" or "Song of Solomon", a book of the Hebrew Bible or Old Testament of the Christian Bible. [ 1 ] [ 2 ] This book is one of the Five Megillot , a group of short books, together with Ruth , Lamentations , Ecclesiastes and Esther , within the Ketuvim , the ...
Approximately every eight minutes, these fields briefly merge, forming a temporary "portal" between the Earth and the Sun through which high-energy particles such as solar wind can flow. The portal takes the shape of a magnetic cylinder about the width of Earth. Current observations place the portal at up to 4 times the size of Earth. [1]
