NASA shows first 'crime scene' photo of Mars landing

About 36 hours after NASA landed its $2.5 billion rover on Mars, it released Tuesday what it jokingly dubbed a "crime scene" aerial shot of where the parachute, heat shield and vehicle came down.

The incredible challenge of landing heavy payloads on Mars

It's too bad Mars is such an interesting place, because it's actually one of the most difficult places to visit in the solar system, especially if you want to bring along a lot of luggage. That planet is a graveyard of missions ...

Mars InSight lander seen in first images from space

On Nov. 26, NASA's InSight mission knew the spacecraft touched down within an 81-mile-long (130-kilometer-long) landing ellipse on Mars. Now, the team has pinpointed InSight's exact location using images from HiRISE, a powerful ...

An answer to green energy could be in the air

(PhysOrg.com) -- In Mark Moore's world, long nanotubes reach into the clouds, serving at once to tether a turbine-vehicle flying at 2,000 feet, or 10,000 feet, or 30,000 feet (610, 3,050 and 9,150 meters); and also to conduct ...

Slipper-shaped blood cells

Red blood cells, which make up 45 percent of blood, normally take the shape of circular cushions with a dimple on either side. But they can sometimes deform into an asymmetrical slipper shape. A team of physicists have used ...

Microbe risk when rover wheels hit martian dirt

Earth microbes trying to make it to Mars must survive sterilization in NASA's clean rooms, harsh cosmic rays during months of space travel, and the Red Planet's unforgiving surface environment. But any bacteria that successfully ...

Parachute

A parachute is a device used to slow the motion of an object through an atmosphere by creating drag. Parachutes are made out of cloth, most commonly nylon. Parachutes are often used to slow the descent of an object falling through an atmosphere. Drogue parachutes are also used to aid horizontal deceleration of a vehicle (a fixed-wing aircraft, or a drag racer), or to provide stability (tandem free-fall, or space shuttle after touchdown). The word "parachute" comes from a French word with a Ancient Greek prefix: "para", meaning "against" or "counter" in Ancient Greek, and "chute", the French word for "fall". Many modern parachutes are classified as semi-rigid wings, which are quite maneuverable, and can facilitate a controlled descent.
