Our Solar System In Focus

Robotic probes launched by National Aeronautics and Space Administration (NASA), the European Space Agency (ESA), and others are gathering information right now all across the solar system. We currently have spacecraft in orbit around the Sun, Mercury, Venus, Earth, Mars, and Saturn. Several others on their way to smaller bodies, and a few on their way out of the solar system entirely. 

 On Mars, a rover called Spirit has just been officially left for dead, after two years of radio silence from it but its twin, Opportunity, continues on its mission, now more than 2,500 days beyond its originally planned 90-days. 

 With all these eyes in the sky, here is a photo album of our Solar system, a set of family portraits, as seen by our astronauts and mechanical emissaries.

When a rather large-sized (M 3.6 class) flare occurred near the edge of the Sun, it blew out a gorgeous, waving mass of erupting plasma that swirled and twisted over a 90-minute period on February 24, 2011. This event was captured in extreme ultraviolet light by NASA's Solar Dynamics Observatory spacecraft . Some of the material blew out into space and other portions fell back to the surface.

History Of NASA Space Shuttle Program

From its first launch 30 years ago to its final launch on July 8, 2011, NASA's Space Shuttle program has seen moments of dizzying inspiration and of crushing disappointment. The program had sent up 135 missions, ferrying more than 350 humans and thousands of tons of material and equipment into low Earth orbit. 

Fourteen astronauts have lost their lives along the way. The missions have always been risky, the engineering complex, the hazards extreme.

Individual Space Shuttle orbiters were named in honor of antique sailing ships of the navies of the world, and they are also numbered using the NASA Orbiter Vehicle Designation system. Three of the names had also been borne by Apollo spacecraft in 1969-1972: Apollo 11 command module Columbia, Apollo 15 command module Endeavour, and Apollo 17 lunar module Challenger.

Lets look back at the past few decades of shuttle development and missions as we await the next steps toward human space flight. Some of the images are awesome and dramatic and suitable to be made as your desktop wallpaper.

How NASA Prepare Space Shuttle For Launching

As a kid, I really want to be an astronaut or cosmonaut. Not because I want to be in outer-space but because I have something inside me that really into heavy machinery. So, as today I already become an engineer, I think it is not really bad at all. 

These pictures shown the amount of thought and engineering that goes into every launch which is hugely immense. In each successful take-off, it represents the Mankind's finest effort, and is a wonder to behold. 

Too bad NASA already terminate the Space Shuttle program. NASA Space Shuttle Pre-Launch Activities.

9 Tallest Mountains In Solar System

Mount Everest, at 29,029 feet tall (5.5 miles), is the tallest mountain on earth. But, not known to many, Hawaii's Mauna Kea is actually much more taller than Everest, which is actually 33,465 feet tall, although only 13,796 of which are above sea level. 

If we look beyond our planet earth, there are lots and lots of taller mountains compare to Everest and Mauna Kea. Following are the tallest mountains in various worlds of the Solar System. Heights are given base to peak.

9. Arsia Mons, Mars > 9 km (5,6 mi)

Arsia Mons is 270 miles (approximately 435 kilometres) in diameter, almost 12 miles high (more than 9 kilometers (5.6 mi) higher than the surrounding plains), and the summit caldera is 72 miles (approximately 110 km) wide. It experiences atmospheric pressure lower than 107 pascals at the summit. Except for Olympus Mons, it is the biggest volcano in volume. Arsia Mons has 30 times the volume of Mauna Loa in Hawaii, the largest volcano on the Earth.

8. Mauna Kea, Earth = 10,2 km (6,3 mi)

Source

Mauna Kea (Hawaii) has an altitude of 4,205 meters (2,6 mi) - much lower than Mount Everest. However, Mauna Kea is an island and if the distance from the bottom of the nearby ocean floor to the peak of the island is measured, then Mauna Kea is taller than Mount Everest.  Mauna Kea is over 10 km (6,2 mi) tall compared to 8.848 m (5,5 mi) for Mount Everest - making it the Earth's tallest mountain.
