NASA’s KaBOOM radar could greatly improve detection and characterization of asteroids

The “Ka-BOOM” NASA project is developing a way to use an array of small high-frequency Ka-band radar dishes to map “nearby asteroids, orbital space debris, water on the Moon and even rover-trapping sand pits on Mars” : NASA Developing Prototype Asteroid-mapping Radar at KSC – SpaceNews.com.

The project was unveiled during a recent visit by NASA Associate Administrator Robert Lightfoot to KSC: NASA Associate Administrator Robert Lightfoot Visits Space Coast and Meets With Media June 3-4 – NASA.

He briefed reporters

on the agency’s new asteroid initiative and NASA’s new Ka-Band Objects Observation and Monitoring (KaBOOM) system, a three-antenna test bed radar array at Kennedy.

NASA recently announced plans to find, study, capture and relocate an asteroid for exploration by astronauts. The asteroid initiative is a strategy to leverage human and robotic activities for a first human mission while accelerating efforts to improve detection and characterization of asteroids.

The goal of KaBOOM is to prove technologies that will allow future systems to characterize near-Earth objects in terms of size, shape, rotation/tumble rate and to determine the trajectory of those objects. Radar studies can determine the trajectory 100,000 times more precisely than can optical methods.

Current NASA radar systems are limited in both resolution and the distance at which they are effective. KaBOOM is the penultimate, low-cost step before proceeding with a high-power, high-resolution radar system. NASA expects this proof of concept to be completed in about two years.

Artist to return remade meteorite to space

ESA assists an artist in sending her recast meteorite back to space:

Meteorite science meets an artist’s dream of spaceflight

28 June 2013:  Inspired by the dream of space exploration, artist Katie Paterson imagined sending a piece of her meteorite artwork back to space in a celebration of science, art and human technology. Her vision may just become reality, with a little help from ESA’s can-do cargo vessel.

Meteorite science meets an artist’s dream of spaceflightCampo del Cielo, Field of the Sky

Paterson’s installation, Campo del Cielo, Field of the Sky, is on display at the UK’s prestigious Turner Contemporary gallery this summer, and features a 4.5 billion-year-old meteorite that has been cast, melted and recast as a model of itself, retaining its original form.

Katie describes Campo del Cielo, Field of the Sky as presenting curious visitors with a newly formed yet still ancient meteorite, imbued with cosmic history.

“The iron, metal and dust inside have been reformed, and the layers of its cosmic lifespan – the intermixing of space and time, the billions of years of pressure and change – have become collapsed, transformed and then, by the hand of human technology, renewed,” she says.

Back to where it came from

While developing the concept for the installation, Katie was struck by an idea: would it be possible to ‘close the story’ of her Campo del Cielo meteorite by returning it back to space?

“By sending it ‘back to space’, I hope to fire the imaginations of students, youth – anyone, really – and foster a discussion on our relation with the wider universe,” she explains.

Seminal fragments of our cosmic origins

For ESA, meteors, meteorites and asteroids are crucial to the scientific understanding of our Solar System, and they are central to numerous Agency activities such as the Rosetta comet mission, future robotic missions to asteroids, near-Earth object studies, Space Situational Awareness and even potential human missions beyond the Earth, Moon and Mars.

“Scientists recognise comets, meteorites and asteroids as the debris left over from the formation of our Solar System,” says Dr Detlef Koschny, responsible for near-Earth object activities at ESA’s Space Situational Awareness office.

“As such, studying them up close, if they fall to Earth, or deep in space, via telescopes or with spacecraft – like ESA’s Rosetta – is vital to understanding how planets and our Solar System emerged.

So, really, objects like this bit of meteorite symbolise a lot of what we are trying to achieve.”

Earlier this year, Katie contacted ESA to enquire if it would be possible to send a symbolic piece of her meteorite to the International Space Station as a way to support public outreach and awareness of the intersection between science and art.

ESA agreed, and has provisionally allocated space on the next Automated Transfer Vehicle, Georges Lemaître, due to voyage to the orbital outpost in 2014. A small sample of the meteorite will be carefully assessed for flight qualification, and if it passes, can be delivered ‘back to space’ to the Station.

“I hope this helps inspire people everywhere to think about the really big questions: the origin of life, the natural history of our Solar System and home planet, and our relationship with time, both geological and cosmic,” says Detlef.

“These are important questions, and space exploration together with art are helping us answer them.”

Rare meteorite turned up in farmer’s field

That strange rock you come across might be from outer space : Farmers’ Rock Turns Out to Be Rare Meteorite | Arlington, Minn. Meteorite – Space.com

On May 30, the couple brought their find to Alexander’s lab and allowed him to chip 0.02 ounces (0.6 grams) off the edge of it for analysis under a scanning electron microscope. The rock was iron, and contained about 8 percent nickel — a telltale giveaway. Iron objects on Earth contain almost no nickel, but iron rocks from space are usually between 5 and 20 percent nickel. The microscope also revealed what’s called a Widmanstätten pattern of nickel-iron crystals that’s unique to meteorites
