Does the moon rotate?
The Moon does not rotate.
The Moon does spin on its axis, completing a rotation once every 27.3 days; the confusion is caused because it also takes the same period to orbit the Earth, so that it keeps the same side facing us..
Can you build an elevator to space?
NASA says the basic concept of a space elevator is sound, and researchers around the world are optimistic that one can be built. The Obayashi Corp., a global construction firm based in Tokyo, has said it will build one by 2050, and China wants to build one as soon as 2045.
How much do astronauts get paid?
Astronauts’ annual salaries are determined using a government pay scale, and starting out, typically fall under two grades: GS-12 and GS-13. According the US government’s 2020 pay scales and a NASA job listing, a civilian astronaut in 2020 can earn between $66,167 and $161,141 per year.
Can we build an elevator to the moon?
A lunar space elevator or lunar spacelift is a proposed transportation system for moving a mechanical climbing vehicle up and down a ribbon-shaped tethered cable that is set between the surface of the Moon “at the bottom” and a docking port suspended tens of thousands of kilometers above in space at the top.
How much does it cost to send 1kg to space?
Between 1970 and 2000, the cost to launch a kilogram to space remained fairly steady, with an average of US$18,500 per kilogram. When the space shuttle was in operation, it could launch a payload of 27,500 kilograms for $1.5 billion, or $54,500 per kilogram.
How much cheaper is SpaceX than NASA?
While that sounds like a lot, it’s a tiny fraction of what existing launches cost: on average, NASA spends an average of $152 million per launch — meaning that, if Musk is to be believed, SpaceX will be able to launch cargo and people into orbit for 1.3 percent of what NASA is currently paying for the same task.
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.
How long does it take to get from space to earth?
It takes the shuttle approximately 8-1/2 minutes to get to orbit. And if you think about it, we’re accelerating a 4-1/2 million pound system from zero miles per hour to its orbital velocity of 17,500 miles per hour in those 8-1/2 minutes. So it’s a heck of a ride for the astronauts.
How long would a space elevator need to be?
This value takes into consideration the entire weight of the space elevator. An untapered space elevator cable would need a material capable of sustaining a length of 4,960 kilometers (3,080 mi) of its own weight at sea level to reach a geostationary altitude of 35,786 km (22,236 mi) without yielding.
Do satellites use fuel?
Satellites do carry their own fuel supply, but unlike how a car uses gas, it is not needed to maintain speed for orbit. It is reserved for changing orbit or avoiding collision with debris.
How fast does SpaceX travel?
As fast as any other rocket that intends to launch a payload into Low Earth Orbit – 17,500 mph, or 28,000 kph.
Has anyone died in space?
As of 2020, there have been 15 astronaut and 4 cosmonaut fatalities during spaceflight. Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire which killed an entire crew of three. There have also been some non-astronaut fatalities during spaceflight-related activities.
Can astronauts have tattoos?
According to Brooklynn Covington who has already researched this: “Although no astronaut to date has had any tattoos during their employment with NASA. NASA currently has no rules against astronauts having visible tattoos. … The Air Force allows a tattoo to cover up to 25% of the body part shown in uniform.
Which is the first country to test space elevator?
JapanJapanese Space-Elevator Experiment Launching to Space Station Next Week (Really!) Space elevators have long been a staple of science fiction. Now, scientists in Japan will test space-elevator tech from the International Space Station.
Is a space tether possible?
A space elevator is possible with today’s technology, researchers say (we just need to dangle it off the moon) Space elevators would dramatically reduce the cost of reaching space but have never been technologically feasible. Until now.
What would happen if a space elevator broke?
If the break occurred at higher altitude, up to about 25,000 km, the lower portion of the elevator would descend to Earth and drape itself along the equator east of the anchor point, while the now unbalanced upper portion would rise to a higher orbit.
Can I pay to go to space?
Depending on where you’re going, a ticket could set you back anywhere from $250,000 to tens of millions of dollars. If you’re looking simply to cross the 62-mile-high Karman line that marks the boundary between the upper atmosphere and outer space, Virgin Galactic says it will take you there for $250,000.
Why is rocket fuel so expensive?
Propellant costs are the smallest part of the cost for rockets. … The reason why getting to orbit is expensive is because your rocket hardware (the upper stage, at least) is going ten times faster than a bullet, so it can’t be easily recovered.
How much weight can you lift in space?
Lifting 100 pounds in microgravity is different than at home. In space, 100 pounds doesn’t feel heavy. So astronauts have to use a special machine that simulates free-weight exercises in normal gravity.
Would a space elevator slow the Earth rotation?
Slowing the climb would allow the space elevator to be drawn back to its stable point, perfectly vertical above the Earth’s equator. But this could also make trips into orbit agonisingly slow, adding nine days or more to a climb that – at several hundred kilometres per hour – might already take about 15 days.
