Mars Curiosity landing sequence demonstrated by NASA

This week the folks at NASA have let loose a video showing the challenges they face in getting to Mars, specifically with the Mars rover Curiosity and how it will be landing on August 5th of this year. The video shows the engineers to designed not only the entry and descent of the new Curiosity mission but the landing system as well, with candid talk on how they have zero – that’s zero – margin for error in this mission. 3D models and projections of the future are also included for full visualization of the situation.

From the top of the atmosphere to the surface you’ve got 7 minutes, with 14 minutes sitting between the signals being sent from the craft back to earth. This means that as these engineers get word that the craft has begun hitting the atmosphere, the craft will have been on the ground in-tact or completely obliterated for 7 minutes already. Beware the ultra-epic music of this film on the Entry Descent and Landing (EDL) of the craft landing on Mars later this year.

You’ll find 1600 degrees encapsulating the craft as its guided downward toward the planet, Mars having a 100 times thinner atmosphere than Earth – this means that as it’s essentially on fire, the craft is going 1,000 miles per hour and relying on a supersonic parachute to slow it down. After the parachute pulls, the craft still goes 200 miles per house, so the lander exits the rest of the craft and uses rockets to push back up and land with a lot less speed. The rover is then set down on the planet to explore – watch all the action above.

Ancient Turtles Died Getting Their Freak on

Bowww-chica-boww-bowww. Scientists discovered fossils this month of ancient turtles that shows several mating pairs that went out in epic style. I imagine it went down like this, girl turtle shouts “OMG we are sinking!” Guy turtle says, “So what?” Scientists discovered the fossilized remains of nine mating pairs of an extinct turtle called Allaeochelys crassesculpta.

These turtles died in the act of procreating and were discovered in the Messel Pit in Germany. This particular location was once the volcanic crater lake in a wet tropical environment. The location was used as a mine in the past for the oil in the shale located there. However, it has since become one of the most important sites in the world for understanding what the environment was like in the Eocene era between approximately 56 million and 34 million years ago.

Other fossils discovered in the area include early horses, reptiles, primates, honeybees, giant ants, birds, and bats. The scientists speculate that the copulating 47 million-year-old turtles died when they sank into the poisonous depths of the lake. This is scientifically important because no vertebrates have been found in a mating state before.

World’s First Pear Genome Sequence Announced by Joint China-US Research Project

World's First Pear Genome Sequence Announced by Joint China-US Research ProjectFruit fans rejoice, pears could be getting bigger, tastier and more resistant to drought and disease! Now that researchers from the Chinese-American "International Pear Genome Cooperation Group" have finished the world’s first pear genome sequence, we can expect new high-yield, high quality, low-input varieties of pears to land on store shelves someday soon.


Calcium Supplement Study: Your Bones Or Your Heart?

Though the majority of physicians recommend calcium supplements for bone
strength, some to women over 40, but most just to postmenopausal women,
there have been studies that indicate that such supplementation is not
the best medicine for heart health.
