Why space debris cleanup might be a national security threat

As an international relations scholar who studies space law and policy, I have come to realize what most people do not fully appreciate: Dealing with space debris is as much a national security issue as it is a technical ...

China has a plan to clean up space junk with lasers

Orbital debris (aka. space junk) is one of the greatest problems facing space agencies today. After 60 years of sending rockets, boosters and satellites into space, the situation in the low Earth orbit (LEO) has become rather ...

ESA boss urges action on 'ticking timebombs' in Earth orbit

A European Space Agency director urged nations Tuesday to unlock concealed data on the whereabouts of hundreds of thousands of pieces of space junk, or "ticking time bombs" threatening spacecraft in Earth orbit.

After 10 years of service, NOAA retires GOES-12 satellite

GOES-12 has seen it all, from Hurricane Katrina that hit the Gulf Coast in 2005, to the Christmas blizzard that crippled the Central United States in 2009. It even traveled south of the equator to provide coverage for South ...

Simulating flow from volcanoes and oil spills

Some time around 37,000 BCE a massive volcano erupted in the Campanian region of Italy, blanketing much of Europe with ash, stunting plant growth and possibly dooming the Neanderthals. While our prehistoric relatives had ...

A new way to see space – even its junk

When a large radio telescope in the Australian outback was unveiled last week its improved sensitivity was immediately apparent. It transformed images of supernova remnants taken with last year's equipment from undefined ...

Astronomers gear up to discover Earth-like planets

If one looks only for the shiniest pennies in the fountain, chances are one misses most of the coins because they shimmer less brightly. This, in a nutshell, is the conundrum astronomers face when searching for Earth-like ...

Measuring the seeds of noctilucent clouds

(Phys.org) —A constant stream of space debris flows toward Earth from the rest of the solar system. Large meteors can sometimes survive the intense friction and heat upon entering Earth's atmosphere, but by and large the ...

Scientists track individual raindrops inside clouds

(Phys.org) -- Naval Research Laboratory (NRL) scientists are leading a multi-agency study which reveals that a very high-resolution Doppler radar has the unique capacity to detect individual cloud hydrometeors in the free ...
