HEARING CHARTER

Threats from Space: A Review of U.S. Government Efforts to Track and Mitigate
Asteroids and Meteors, Part 1

Purpose

The Committee on Science, Space, and Technology will hold a hearing titled
"Threats from Space: A Review of U.S. Government Efforts to Track and Mitigate
Asteroids and Meteors, Part 1." This is the first in a series of hearings
examining the tracking, characterization and mitigation of Near Earth
Objects. The hearing will provide Members of the Committee the opportunity
to receive testimony regarding the ongoing work, planned efforts, and
coordination procedures within the National Aeronautics and Space Administration,
the Office of Science and Technology Policy, and the U.S. Air Force Space
Command.

Witnesses:

o The Honorable John P. Holdren, Director, Office of Science and Technology Policy,
  Executive Office of the President
o Gen. William L. Shelton, Commander, U.S. Air Force Space Command
o The Honorable Charles F. Bolden, Jr., Administrator, National Aeronautics
  and Space Administration

Overview

On Friday, February 15, 2013, two events occurred that received worldwide attention.
An unforeseen meteor (estimated 50 feet in diameter) exploded in the sky above the
Russian city of Chelyabinsk releasing the equivalent of a 300 kiloton bomb, about
twenty times the explosive energy of the atomic blast used over the city of Hiroshima.
This blast injured nearly 1,200 people and resulting in an estimated $33
million in property damage. On the same day, a small asteroid (150 feet
in diameter) discovered by amateur astronomers and tracked closely by
NASA passed safely by the Earth, but within the orbital belt of geostationary
satellites. Until it entered our atmosphere, the Russian meteor went completely
undetected. According to NASA, the two events were unrelated, but raised public
awareness of the potential threat from Near Earth Objects (NEOs). Today's hearing
will cover the U.S. government's plans and programs to track, classify, and mitigate
the threat of NEOs. A second hearing is planned this month to address international,
commercial private sector, and philanthropic initiatives to survey the sky for
asteroids and comets.

>From these two incidents, many questions arose, among them:

o Do we have the tools and technology necessary to detect and track Near Earth Objects?

o How often do we currently observe large meteors entering the atmosphere safely
  over the ocean?

o Are we tracking the right size objects, specifically the ones that can cause
  significant harm on Earth?

o Once we identify an object, what are our means of tracking it?

o What are our contingencies and mitigation capabilities if we determine there is a
  threat to the Earth from a NEO impact?

o What process exists amongst government agencies, both foreign and domestic, in such
  an instance?

The Science, Space, and Technology Committee has been on the forefront of the issues
surrounding Near Earth Objects. For example, the NASA Authorization Acts of 2000 and
2005 directed NASA to conduct a survey of the population of NEOs and study
mitigation plans. Astronomers estimate 20,000 potentially hazardous asteroids
orbit within the vicinity of the Earth.
