Something about Space Walk

Spacewalks technically called extravehicular activity or EVA are the finest examples of human innovation encourage. It is any activity done by an astronaut or cosmonaut outside of a spacecraft beyond the Earth's appreciable atmosphere.

Here are 5 incredible aspects about a spacewalk according to NASA:

5. You might get in trouble with a car for driving over 60 to 70 miles per hour; now matching going 17227 miles an hour, that's the average speed of the International Space Station astronauts get out of their protective environment inside the space station to perform a spacewalk.

4. The temperatures that astronauts face during a spacewalk could range from 250 degrees Fahrenheit to -250 degrees Fahrenheit depending on their position. What's the temperature like in your neck of the woods today?

3. For typical spacewalk astronauts may utilize anywhere from 70 to 110 tools.

2. It takes about 45 minutes to put on a spacesuit; before heading out the astronauts brief pure oxygen for more than an hour. BTW, putting on a species called donning and taking it off is called doffing.

1. Susan J Helms and James S Voss hold the current record at 8 hours 56 minutes for the longest spacewalk. How do you like the idea being out in space from most nine hours traveling at thousands of miles per hour?

As for writing, it reminds me about the movie Gravity. A lot of people like it, but it's hilarious to me somehow. For example, Stone is sent spinning into outer space after the debris hits the Explorer. Kowalsky uses his MMU to find her and bring her back to the shuttle. But in real life, during spacewalks, astronauts are required to wear a SAFER (Simplified Aid for EVA Rescue), which is a more basic version of the MMU. It is intended for emergencies only, and Stone would not have been repairing the Hubble without one. She may not have been able to get back all the way back to the Explorer with it, but it would have been her first line of defense against the prospect of drifting off forever.

That's all I can tell about space walk, and the critique for the movie Gravity: nah.... 

Fun Facts about Our Solar System

While we all remember some facts about the solar system - for example, there were night planets, but now are down to eight,  - there are many little things that many people do not know. So, here we go:

• Saturn Isn't The Only Planet With Rings
• Most of us learned that Saturn had rings made up of small rocks, ice, and other particles. Actua;;y, there are several other planets have rings around them! Such as all of the larger planets, and Uranus, but these are all too difficult to see due to their distance to earth.

• The Solar System’s Mass Is 99% Sun
• The sun makes up over ninety-nine percent of all of the mass in our entire solar system. Jupiter and some of the other large planets make up most of the rest, and Earth barely even registers in the equation.

• Seasons On Uranus Last For Twenty Years
• Uranus has an orbital tilt of eighty-two degrees, which means that it is practically on its side. The effect of this is that a season on Uranus lasts about twenty earth years, and causes all sorts of odd weather.

• One Day On Mercury Equals 58 Earth-Days
• Due to Mercury’s orbit around the sun, a year on that planet is the equivalent of around eighty-eight Earth days—which means that on Mercury, there are less than two days in a year. But that’s not all: due to the planet’s strange orbit, the sun actually seems to travel backwards and forwards in the sky.

• Venus Is The Hottest Planet
• Venus, on the other hand, has a notoriously thick atmosphere that traps the heat created by the sun. Interestingly, Venus is also quite the black sheep of the planet world, and spins in the opposite direction.

• There Are Five Dwarf Planets In Our Solar System
• There are actually five dwarf planets in our solar system; one of them is Pluto which has been reclassified few years ago. The other four are Ceres, Eris, Haumea, and Makemake.

• Jupiter Sucks Up Space Garbage
• Jupiter’s huge size and gravitational pull act as a protective barrier that shields the earth from space debris, pulling dangerous objects into its own orbit before they can reach us.
