Landsat Program Background The Landsat Program has continuously acquired

synoptic images of the Earth’s land surfaces for 30 years

DOI/USGS preserves this record in the National Satellite Land Remote Sensing Data Archive and distributes public-domain data to users worldwide

Landsat Program vision: Acquire multispectral imagery affording global,

synoptic, repetitive coverage of the Earth's land surfaces at a scale where natural and human-induced changes can be detected, characterized, and monitored over time

Rodeo-Chediski Wildfires

Landsat 7 June 21, 2002

Landsat 5 June 29, 2002

Landsat 7 July 7, 2002

These images show the Rodeo fire, which began on June 18th, and the Chediski fire which began on June 20th. When they merged together, the combined Rodeo-Chediski fire became the largest wildfire in Arizona history.

Together these wildfires have destroyed over 468,000 acres in the Apache-Sitgreaves National Forest and Fort Apache reservation. 400 homes have been destroyed, and over 30,000 people have been evacuated. It has cost the state of Arizona more than $2 million a day, a total of over $32 million, to fight the Rodeo-Chediski fire.

Landsat Program BackgroundLand Remote Sensing Policy Act of 1992 (P.L. 102-555)

Directs Landsat Program Management (NASA/DOI) to study Landsat 7 successor options that:

“adequately serve the civilian, national security, commercial, and foreign policy interests of the United States”

“maintain data continuity with the Landsat system” “incorporate system enhancements…”

Lists four study options: Private sector funding and management International consortium U.S. Government funding and management U.S. Government-private sector cooperative effort

Landsat Program Background

Commercial Space Act of 1998 (P.L. 105-303)

Addresses “Promotion of Commercial Space Opportunities” including commercialization of Space Station, acquisition of space science data and Earth science data, and commercial launch services

Directs NASA and other Federal agencies to “…acquire, where

cost-effective…remote sensing data, services, distribution, and applications from commercial provider.”

Landsat Data Continuity Mission (LDCM) was conceived as a bridge to true Government “scientific data buys” in the future

LDCM Background

In June 1999, NASA and the USGS released a request for information (RFI) to private industry regarding plans to acquire Landsat-like data

Results: No respondent considered the commercial market for

30m data sufficient for private funding of a Landsat 7 follow-on system

No respondent had plans to develop a system to acquire 30m data

Respondents favored Government procurement of 30m data from a privately-owned system

Innovative funding strategies were suggested

LDCM Strategy NASA and the USGS intend to procure LDCM data from

a privately-owned and privately-operated remote sensing system

NASA and the USGS are implementing a two-phase procurement process based on an LDCM Data Specification and Data Policy

Phase I: Formulation “Study phase” for various technical and trade studies Two bidders selected for funding: Digital Globe and Resource 21

(DG and R21) Culminated in preliminary system design

Phase II: Implementation Selection of LDCM contractor through new round of proposals Final design, fabrication, launch, and checkout On-orbit data delivery

Procurement Strategy The procurement DOES NOT

Specify spacecraft, instrument(s), ground system, or operational concepts or designs

Require Government oversight Require the Government to “take title” to the system Require the Government to operate the system

The procurement DOES Specify data and its delivery to the Government’s archives Establish a policy for the distribution of LDCM data products Specify March 2007 start date for 5 years of operational data

delivery (plus 5-year option) Require Government insight and data validation Encourage commercial approaches for servicing the International

Cooperator market Facilitate sharing of cost, risk, and rewards in a Government-

private sector cooperative effort

LDCM Data LDCM data are described by the LDCM Data Specification

Specifies the quantity and qualities of the LDCM data to be procured by the Government (radiometry, geometry, products, bands, resolution)

Specifies seasonal coverage of global land surfaces 16 day repeat coverage required for U.S. 250 global scenes per day (average) to an active archive at the USGS EROS

Data Center Addition of a Coastal / Aerosol band (.443 m and 30m GSD)

and Cirrus band (1.33 m or 1.88 m and 120m GSD) No Thermal Infrared bands included Unenhanced data products to be derived and distributed by

the USGS from the LDCM data in the active archive

Draft Data Policy Similar to Landsat 7 data policy

Ensures non-discriminatory access to Level 1 data products derived from Government-procured LDCM data

No restrictions on the use, resale, distribution or sharing of LDCM data products Timely delivery Data product pricing is critical issue; striving towards $50/scene products

Distribution of Level 0 data products may be restricted Protects LDCM contractor’s commercial rights to data exceeding

quantity or specifications of the procured LDCM data. Government will not restrict:

Value-added products derived from LDCM data Marketing of data acquired and generated in excess of Government data buy

End of “Official” Presentation

Now some questions……

What Does the Gov’t Want?

Solicitation Objectives:1. Implement a process to acquire Landsat

compatible data and produce products required to meet the research and operational needs of the Government.

2. Reduce the Government’s cost and risk by partnering

3. Encourage the expansion of the remote sensing industry

4. Fulfill these objectives through the Government’s procurement from an Industry-owned system

Criteria

(In decreasing importance:)

Mission Suitability > Price > Past Performance

The price factor is significantly less important that the combined importance of the Mission Suitability Factor and the Past Performance Factor.

As individual Factors, the Price Factor is less important that the Mission Suitability Factor but more important than the Past Performance Factor.

Risks

Upside: Each side “shares” risk? Contractor can get insurance, i.e. risk

mitigation for both sides? Downsides

Now gov’t has to deal with business risk – not just technical risk

(Will the company be there?)

The “Hard Questions”

Is it “Continuity”? Missing/changed/added spectral bands Perhaps it is “continuity”, although not

perfect “fidelity” Can both sides benefit?

Will gov’t (i.e. constituents) get all the data wanted?

Will Business still have profit potential? How closely can they work together?

The International Scene

Landsat has a

The International Scene

Landsat has a huge network of International Cooperators (ICs)

A long-lived partnership in space since 1972!

LDCM very noncommittal on ICs Will gov’t abandon this long-running

international relations coup? Will industry support it?

Is There a Market?

Market has never been there for 30m data, still not there. But that’s what the gov’t wants

Both formulation phase vendors proposed significant technological advances to improve data marketability. Those technical advances increase

complexity, add technical challenges, increase costs and raise risks.

The Big Question:

Will the Landsat Mission ever find a home? Or will it forever be a “nomad” mission?

Answers?

USGS Director and NASA Administrator for Earth Science to meet soon (Delayed by Isabela)

Decision coming soon? Stay tuned….
