NASA spots massive asteroid approaching Earth on February 15: Report

The report quoted NASA saying it is bigger than the largest man-made structure in the world.

United States space agency NASA has spotted a massive, hazardous space rock that might approach the Earth very soon, possibly on February 15.
According to the Express UK, NASA’s asteroid tracker spotted a Near-Earth Object (NEO), named 2002 PZ39, moving towards the Earth at a very high speed, at 57,240 km per hour precisely.
What’s alarming is the estimated size of the asteroid. Scientists have classified it as a Potentially Hazardous Object (PHO) because of its diameter spanning 3,280 feet. The report quoted NASA saying it is bigger than the largest man-made structure in the world.
The report noted that given the PZ39 is classified as a PHO, if it happens to pierce through our atmosphere and collide with the Earth’s surface, it has the potential for destruction on a continental, or global scale.
To put it into perspective, the asteroid that might have led to the extinction of the dinosaurs 66 million years ago from the face of Earth was 10 km in diameter. If this asteroid does hit us, then the impact, which is equivalent to blowing up more than 60 megatons of TNT, may trigger a nuclear winter that can threaten the very existence of living beings.
PZ39 is an Apollo asteroid, which means it intersects the path of our planet quite often while moving around the Sun. Since it traces an Earth-crossing orbit, the chances of a collision remain high every time it moves this way.

You may soon be able to ride to the edge of space from Alaska in a Balloon Florida-based startup firm Space Perspective plans to use the Pacific Spaceport Complex in Kodiak to serve as one of the launch sites for the vehicle, called the Spaceship Neptune A company wants to use an advanced balloon to fly customers from Earth’s surface in Alaska to the highest reaches of the planet’s atmosphere. Florida-based startup firm Space Perspective plans to use the Pacific Spaceport Complex in Kodiak to serve as one of the launch sites for the vehicle, called the Spaceship Neptune,  The Anchorage Daily News  reported on Sunday. The balloon rides will be manned by a flight crew taking eight passengers in a pressurized capsule suspended beneath a hydrogen balloon the size of a football stadium. Each passenger could pay an estimated $125,000 for a six-hour journey. Mark Lester, CEO of Alaska Aerospace Corp., said the high-altitude rides will be available from Kodiak in a few years and will ...

Committee recommends review of planetary protection policies

Committee recommends review of planetary protection policies WASHINGTON — The NASA Advisory Council has recommended that NASA review its existing planetary protection guidelines to balance the needs of science and exploration, an effort that could set the stage for a similar revision at the international level. The council, during a two-day meeting at NASA Headquarters Dec. 10–11, adopted a recommendation calling on NASA to establish an interdisciplinary committee of experts to review the agency’s current requirements for preventing contamination of other worlds by NASA spacecraft as well as any contamination of the Earth by materials brought back from those worlds. “NASA should establish a multidisciplinary task force of experts from industry, the scientific community, and relevant government agencies, to develop U.S. policies that properly balance the legitimate need to protect against the harmful contamination of the Earth or other celestial bodies with the scientific, social, and e...

Surprise! There's more water on Jupiter than anyone thought

Surprise! There's more water on Jupiter than anyone thought Jupiter  appears to have more water than anyone expected. Newly released data from  NASA's Juno probe shows that water may make up about 0.25% of the molecules in the atmosphere over Jupiter's equator. While that doesn't sound like much, the calculation is based on a prevalence of water's components, hydrogen and oxygen, three times more than at the sun. The new measurements Juno obtained are much higher than a previous mission suggested. The surprise result has scientists delving deep again into results from  NASA's Galileo mission to Jupiter , which obtained drier results in 1995 when engineers deliberately threw the spacecraft into Jupiter's atmosphere. (Galileo was low on fuel and NASA didn't want to take the chance, even if it was a slight one, of the spacecraft accidentally crashing on a potentially habitable icy moon.) Reconciling the results from Galileo and Juno is key for sc...
