Solar System: Things to Know This Week

Go for Venus! Fifty-five years ago this week, Mariner 2, the first fully successful mission to explore another planet launched from Cape Canaveral in Florida. Here are 10 things to know about Mariner 2.

1. Interplanetary Cruise 

image

On August 27, 1962, Mariner 2 launched on a three and a half month journey to Venus. The little spacecraft flew within 22,000 miles (about 35,000 kilometers) of the planet. 

2. Quick Study 

image

Mariner 2’s scan of Venus lasted only 42 minutes. And, like most of our visits to new places, the mission rewrote the books on what we know about Earth’s sister planet.

3. Hot Planet 

image

The spacecraft showed that surface temperature on Venus was hot enough to melt lead: at least 797 degrees Fahrenheit (425 degrees Celsius) on both the day and night sides.

4. Continuous Clouds 

The clouds that make Venus shine so bright in Earth’s skies are dozens of miles thick and permanent. It’s always cloudy on Venus, and the thick clouds trap heat - contributing to a runaway “greenhouse effect.”

5. Night Light 

image

Those clouds are why Venus shines so brightly in Earth’s night sky. The clouds reflect and scatter sunlight, making Venus second only to our Moon in celestial brightness.

6. Under Pressure 

Venus’ clouds also create crushing pressure. Mariner 2’s scan revealed pressure on the surface of Venus is equal to pressure thousands of feet under Earth’s deepest oceans.

7. Slow Turn 

Mariner 2 found Venus rotates very slowly, and in the opposite direction of most planets in our solar system.

8. Space Travel Is Tough 

Mariner 2 was a remarkable accomplishment, considering that in 1962 engineers were still in the very early stages of figuring out how operate spacecraft beyond Earth orbit. The first five interplanetary missions launched - by the U.S. and Soviet Union, the only two spacefaring nations at the time - were unsuccessful.

9. Not Ready for Its Close Up 

Mariner 2 carried no cameras. The first close-up pictures of Venus came from NASA’s Mariner 10 in 1974.  

10. Hot Shot

The first (and still incredibly rare) photo of the surface of Venus was taken by the Soviet Venera 9 lander, which survived for a little more than a minute under the crushing pressure and intense heat on the ground.

A View Of The Apollo 11 Lunar Module “Eagle” As It Returned From The Surface Of The Moon To Dock

A view of the Apollo 11 lunar module “Eagle” as it returned from the surface of the Moon to dock with the command module “Columbia”. A smooth mare area is visible on the Moon below and a half-illuminated Earth hangs over the horizon. The lunar module ascent stage was about 4 meters across. Command module pilot Michael Collins took this picture just before docking at 21:34:00 UT (5:34 p.m. EDT) 21 July 1969. (Apollo 11, AS11-44-6642)

NASA Study Proposes Airships & Cloud Cities For Venus Exploration

NASA Study Proposes Airships & Cloud Cities for Venus Exploration

The surface of Venus isn’t going to work for humans, but what if we ignore the surface and stick to the clouds? Dale Arney and Chris Jones, from the Space Mission Analysis Branch of NASA’s Systems Analysis and Concepts Directorate at Langley Research Center, in Virginia, have been exploring that idea. Perhaps humans could ride through the upper atmosphere of Venus in a solar-powered airship. Arney and Jones propose that it may make sense to go to Venus before we ever send humans to Mars.

Hinode Views the 2012 Venus Transit

On June 5, 2012, Hinode captured these stunning views of the transit of Venus — the last instance of this rare phenomenon until 2117. Hinode is a joint JAXA/NASA mission to study the connections of the sun’s surface magnetism, primarily in and around sunspots.

Stephen Hawking: a brief history of genius

London (AFP) March 14, 2018 Stephen Hawking, who has died aged 76, was Britain’s most famous modern day scientist, a genius who dedicated his life to unlocking the secrets of the Universe. Born on January 8, 1942 - 300 years to the day after the death of the father of modern science, Galileo Galilei - he believed science was his destiny. But fate also dealt Hawking a cruel hand. Most of his life was spent in Full article
