Entry, Descent & Landing for Mars Science Laboratory Curiosity - 7 Minutes of Terror

When Mars Science Laboratory (MSL) Curiosity performs its entry, descent and landing (EDL) sequence, it will be 7 minutes of terror. 

"EDL is referred to as the 7 minutes of terror because we've got literally 7 minutes to get from the top of the atmosphere to the surface of Mars. Going from 13000 miles per hour to 0, in perfect sequence, perfect choreography, perfect timing... If any one things doesn't work just right it's game over" - Tim Revellini, EDL Engineer for MSL Curiosity.

Below is the NASA/JPL video about landing Curiosity on Mars. Touchdown is anticipated at 0131 ET on 6 Aug 2012!


SpaceX Plans for a Completely Reusable Falcon 9 Rocket

SpaceX has unveiled plans to create and begin testing a completely reusable Falcon 9, though a date for such a test has not been established. SpaceX is hoping to lower costs of launches by allowing the same hardware to be recycled over and over. These plans are in line with SpaceX's stated goal of bringing the cost per launch to $50-$100 per pound, down from the typical $10000 per pound. 

The concept video for the idea has been reproduced below. I suggest making it full screen so you see the details. The original can be found on the SpaceX website.

The closest thing to a reusable launch system was the shuttle, with the orbiter and two solid rocket boosters able to be reused after several months of refitting work. The average cost per shuttle launch was $1.5 billion, with a cost of over $10000 per pound every launch. As Elon Musk, the founder and CEO of SpaceX states, creating a reusable Falcon 9 will "allow for about a 100 fold reduction in launch costs."

While a date has not been established for testing their reusable Falcon 9 concept, this will not be the first time SpaceX has revolutionized the space industry. To see more on their accomplishments check out the SpaceX website!

I previously wrote an article on why SpaceX is winning the race to Mars, which discusses some of their many  accomplishments and plans.
