Changes in cataloged objects in orbit around Earth over 50 years

Build a high power, high resolution radar system for: •  Precision tracking and characterization of near

Earth objects to: •  Save the Earth from Asteroid impacts •  Select asteroids for human exploration

•  Tracking orbital debris •  Down to 5 cm at GEO •  Protect astronauts on the ISS and

satellites up to GEO

Orbit determination 100,000 times more precise than by optical means.

0.5 AU capability for tracking and characterizing NEO’s

0.1 AU Current capability for tracking and characterizing NEO’s:

NASA Primary Goals

1963 2013

TheDemonstra3onProject•  Phased Array, 3 – 12m diameter antennas

•  Eventually operate near 30 GHz •  Main features are the ability:

•  to produce phase-aligned signals at a distant target without external calibration

•  to use a downlink signal (if one is simultaneously present) to measure the effects of tropospheric turbulence along the signal paths and apply real-time corrections to the uplink signal.

1 of 3 0.8 m Site Test Interferometer antennas

1/27/2016 31

•  An STI constructed by Jet Propulsion Laboratory (JPL) has been implemented at KSC.

•  It uses three small antennas to receive signals from a commercial geostationary satellite in order to measure the effects of turbulence in the atmosphere on space communication and radar signals.

•  The STI will help KaBOOM determine: •  how much its signals are being disrupted by the atmosphere, and •  provide a measure of how well KaBOOM's atmosphere compensation

process is working.

•  Government-only launches •  2-4 launches per month •  1 Big Customer •  Self-sufficiency Model •  Solely USAF Range •  Upper air data (Balloons only) •  Initial Lightning Launch Commit

Criteria (LLCC) development •  Accidents attributed to wx

•  Majority commercial launches •  2-4 launches per month •  Many Med/Small Customers •  Buy-by-the-pound Model •  USAF and FAA-licensed launches •  Upper air data (Balloons, Doppler

Radar Wind Profiler (DRWP)) •  Gradual refinement of LLCC •  Limited Space Wx assessment •  No recent accidents due to wx

• Reductions (AMU, buoys) • Complex budget process • Workforce unfamiliar with state prior to weather incidents

• Continuous demand for increased support for less cost

Effects

•  Government, commercial, tourist launches •  2-4 launches per week •  Numerous small launches •  Weather funded by commercial users? •  50% or more Federal Aviation Agency

(FAA)-licensed launches •  Upper air data (DRWP, radar, satellite) •  LLCC less conservative & reliant on

instrumentation •  Localized, tailored Space Weather

evaluation •  Tailored, geolocated wx watches/warnings •  Goal: 0 accidents, reduced scrubs/delays
