cylonlover writes “The SpaceX Grasshopper vertical takeoff vertical landing (VTVL) testbed has successfully flown to a height of 40 meters (131 ft), hovered for a bit and subsequently landed in a picture perfect test on December 17, 2012. The Grasshopper had previously taken two hops to less than 6 m (20 ft) in height, but the latest test was the first that saw it reach an altitude taller than the rocket itself, which is a modified Falcon 9 orbital launch vehicle. The flight lasted 29 seconds from launch to landing, and carried a 1.8 m (6 ft) cowboy dummy to give an indication of scale.”

Scientists Stack Up New Genes For Height

September 30th, 2010 09:12 admin View Comments

An anonymous reader writes “An international team of researchers, including a number from the University of North Carolina at Chapel Hill schools of medicine and public health, have discovered hundreds of genes that influence human height. Their findings confirm that the combination of a large number of genes in any given individual, rather than a simple “tall” gene or “short” gene, helps to determine a person’s stature. It also points the way to future studies exploring how these genes combine into biological pathways to impact human growth.”

NASA Creates First Global Forest Map Using Lasers

MikeCapone writes “Scientists, using three NASA satellites, have created a first-of-its-kind map that details the height of the world’s forests. The data was collected from NASA’s ICESat, Terra and Aqua satellites. The latter two satellites are responsible for most of NASA’s Gulf spill imagery. The data collected will help scientists understand how the world’s forests both store and process carbon. While there are many local and regional canopy maps, this is the very first global map using a uniform method for measure.”

How-To Wiki: Estimate the Height of Tall Objects

Determining the height of tall objects from a glance doesn’t require a prohibitively large tape measure — just a little math, a sharp eye and a protractor.

STEREO Satellites Spot Solar Flare Tsunami

November 25th, 2009 11:08 admin View Comments

westtxfun writes “The STEREO satellites recently confirmed the existence of solar mega-tsunamis when they captured height data after a sunspot recently erupted. The scale of this tsunami literally dwarfs the Earth’s diameter — it was 62,000 miles high and raced across the surface at 560,000 mph! STEREO A and B orbit 90 degrees apart and luckily, one was overhead while the other saw the eruption on the limb. This gave NASA scientists enough data to confirm the tsunami wasn’t a shadow, solving a modern solar mystery. The images are simply stunning, to boot.”
