- The region near Earth is filled with remnants leftover from the solar system's formation long ago: asteroids and comets. Work is ongoing to catalog and track Earth-approaching objects, and to understand the frequency and energy with which they can potentially impact Earth. Much progress has been made in recent years, resulting in the discovery of the majority of near-Earth objects large enough to cause global devastation. However, more work remains to be done, as the majority of asteroids and comets large enough to cause severe regional damage have yet to be found. The process of searching for and characterizing Earth-approaching objects also teaches us about the rest of the asteroid and comet populations throughout the solar system, helping us understand its assembly and evolution.
We are pleased that Dr. Amy Mainzer will be speaking at our event in May! Dr. Mainzer is the Principal Investigator of NEOWISE, a mission studying asteroids and comets using the reactivated Wide-field Infrared Survey Explorer satellite and run from NASA's Jet Propulsion Laboratory in Pasadena, CA. She is also the Principal Investigator of Near Earth Object Camera (NEOCam), a proposed NASA Discovery mission selected for extended Phase A study in January 2017. In 2012, Dr. Mainzer was awarded the NASA Exceptional Scientific Achievement Medal. Her research interests include asteroids, brown dwarfs, planetary atmospheres, debris disks, star formation, and the design and construction of new ground- and space-based instrumentation. Dr. Mainzer has appeared a number of times in the History Channel series The Universe and events hosted by NASA TV.

Amy Mainzer, brilliant as always!
Would be so neat to meet Amy, being a geologist, I find the universe fascinating!
I admire this extremely smart and gorgeous lady! I wish I could meet her in person someday.
I have an infinite amount of questions for Dr. Mainzer...
I had a meteorite break up over head, over the Sierra Nevada Mountain Range in April 2012, and it caused a loud boom as it entered the the lower atmosphere, I was there for it. Found an article on it: “A meteorite that exploded as a fireball over California’s Sierra Nevada foothills April 22 and heard throughout the Lake Tahoe Basin was among the fastest, rarest meteorites known to have hit the Earth, and it traveled a highly eccentric orbital route to get here.
An international team of scientists presents these and other findings in a study published Friday, Dec. 21, in the journal Science. The 70-member team included nine researchers from UC Davis, along with scientists from the SETI Institute, NASA and other institutions.
The researchers found that the meteorite that fell over Northern California was the rarest type known to have hit the Earth - a carbonaceous chondrite. It is composed of cosmic dust and presolar materials that helped form the planets of the solar system.”
Just incredible....☄⚡🤘🏁
Nice information
Was in Mexico on a vacation heard a sonic boom and there was a huge in the sky it was in 1997 on July. The Meteor ( fireball) from the time it entered the atmosphere to the time it next to me it was about 56 seconds. It was the size of a standard trolley or local commuter bus when it passed. It burned bright white with fragments ripping off from the front to the tail . To put in perspective the height was like stacking 2 telephone or power line poles so about 40 to 50 feet high and was like looking at the distance of the house across the street that is how close it was. From the time had 1st it to at about 35 seconds had felt the shock wave up against my body at 40 seconds started feeling the heat radiating from the Meteor and got hotter as it passed by. Thought it was going to hit the ground (meteorite level) or hit a mountain.
After returning from the vacation there was an article on the
LA TIMES it was 1st seen in Australia, traveled across the Pacific Ocean through Mexico through the Gulf of Mexico up to Maine.... they mentioned in outer space it was traveling 120,000 miles per hour, and had slowed down to 75,000 mph. It didn't explode like the Chelybinsk Meteor
Because of Earths rotation around the sun and its spin rotation on it's axis it missed being the destructive bullet of space. I would say keep looking for these destructive destroyers of life.
Amy keep doing your exceptionally great job and see soon I your in the night shift. Take care
What a beautiful woman. I wish they would have zoomed in on her
I know right...Sheldon was filming this.....lol.
Elle ressemble, à moins que ce soit l'inverse, à Anne, Anne Hataway.
Amy proves that's it's difficult to learn about science when you have an erection lasting over 4 hours.
