Finalizing my geonews catching up, here's the recent Direction Magazine articles that I wanted to share with our readers.

Landsat 8 Satellite Successfully Launches Into Orbit

I'm currently abroad but wanted to share the good news that Landsat 8 Satellite Successfully Launches Into Orbit.

The Slashdot summary: ""The Landsat Data Continuity Mission is now in orbit, after launching Monday from Vandenberg Air Force Base in Calif. After about three months of testing, the U.S. Geological Survey will take control and the mission, renamed Landsat 8, will extend more than 40 years of global land observations critical to energy and water management, forest monitoring, human and environmental health, urban planning, disaster recovery, and agriculture." We still need more new observation satellites to avoid losing Earth observing capabilities as the work horses of the NASA/USGS fleet die of old age."

Everything You Need to Know about Landsat 8

That's the name of a recent DM article, Everything You Need to Know about Landsat 8. From the article: "It is anticipated that over 400 images per day will be collected, the most ever by any previous Landsat satellite."

From the NASA press release: ""LDCM will be the best Landsat satellite yet launched in terms of the quality and quantity of the data collected by the LDCM sensors," said Jim Irons, LDCM project scientist at Goddard. "OLI and TIRS both employ technological advances that will make the observations more sensitive to the variation across the landscape and to changes in the land surface over time."  OLI will continue observations currently made by Landsat 7 in the visible, near infrared, and shortwave infrared portions of the electromagnetic spectrum. It also will take measurements in two new bands, one to observe high altitude cirrus clouds and one to observe water quality in lakes and shallow coastal oceans as well as aerosols. [...] TIRS will collect data on heat emitted from Earth's surface in two thermal bands, as opposed to the single thermal band on previous Landsat satellites. Observations in the thermal bands are vital to monitoring water consumption, especially in the arid western United States."

RADARSAT Constellation Project Confirmed, Operational in 2018

Via internal email, I learned that a few minutes ago the Government of Canada announced the final stage of the RADARSAT Constellation project.

From the press release: "The contract with MacDonald Dettwiler and Associates (MDA), announced today, will lead to the completion of construction; the launch of the three satellites, planned for 2018; and the first year of operation of the mission."

Technical details available here, "The RADARSAT Constellation is the evolution of the RADARSAT Program with the objective of ensuring data continuity, improved operational use of Synthetic Aperture Radar (SAR) and improved system reliability. The three-satellite configuration will provide complete coverage of Canada's land and oceans offering an average daily revisit, as well as daily access to 95% of the world to Canadian and International users."

WMO OSCAR: Observing Systems Capability Analysis and Review Tool

Those of you doing remote sensing or have an interest in satellite capabilities will be interested by the WMO O.S.C.A.R. online tool; the 'Observing Systems Capability Analysis and Review' tool. There's a 10-minutes screencast that demonstrate what OSCAR can do for browsing satellites capabilities based on specific needs and variables. The tool is very well done and easy to use.

OSCAR is described like this: "OSCAR is a resource developed by WMO in support of Earth Observation applications, studies and global coordination. It contains quantitative user-defined requirements for observation of physical variables in application areas of WMO (i.e. related to weather, water and climate). OSCAR also provides detailed information on all earth observation satellites and instruments, and expert analyses of space-based capabilities."

U.S. In Danger of Losing Earth-Observing Satellite Capability

That's the name of the Slashdot story, U.S. In Danger of Losing Earth-Observing Satellite Capability.

Their summary: "As reported in Wired, a recent National Research Council report indicates a growing concern for NASA, the NOAA, and USGS. While there are currently 22 Earth-observing satellites in orbit, this number is expected to drop to as low as six by the year 2020. The U.S. relies on this network of satellites for weather forecasting, climate change data, and important geologic and oceanographic information. As with most things space and NASA these days, the root cause is funding cuts. The program to maintain this network was funded at $2 billion as recently as 2002, but has since been scaled back to a current funding level of $1.3 billion, with only two replacement satellites having definite launch dates."

UK Plans Space-Based Radar System 'NovaSAR-S'

Slashdot discusses a story named UK Plans Space Based Radar System.

Their summary: "The UK government is to kick-start an innovative project to fly radar satellites around the Earth, with an initial investment of £21m. NovaSar-S would have a number of viewing modes that could enable it to perform a wide range of roles, from flood monitoring and land cover management to disaster mapping and maritime enforcement — notably ship tracking and oil spill detection."

Those wanting to learn more will find the SSTL NovaSAR-S brochure and datasheet here. Some info: S-Band radar, maximum spatial resolution of 6 meters (stripmap mode), single, dual and triple polarization capabilities.

Landsat 5 Mission in Jeopardy

SS informed us that the USGS reported that the Landsat 5 mission is in jeopardy.

From the USGS: "The U.S. Geological Survey (USGS) has stopped acquiring images from the 27-year-old Landsat 5 Earth observation satellite due to a rapidly degrading electronic component. Landsat 5 was launched in 1984 and designed to last 3 years. The USGS assumed operation of Landsat 5 in 2001 and managed to bring the aging satellite back from the brink of total failure on several occasions following the malfunction of key subsystems. There is now an increasing likelihood that the Landsat 5 mission is nearing its end. [...] For several months, the Landsat flight operations team has been closely tracking the fluctuating performance of an amplifier essential for transmitting land-surface images from the Landsat 5 satellite to ground receiving stations in the U.S. and around the world.  Over the past 10 days, problems with the amplifier have led to drastically reduced image download capabilities, a sign of impending failure. [...] Landsat 8, currently called the Landsat Data Continuity Mission, is now scheduled to be launched in January 2013."

We obviously mentioned Landsat 5 often in the past, including in 2005, 2007 and 2009 when it suffered technical problems, but each time, was able to resume satellite imagery acquisition. This time, it's probable it's really the end of Landsat 5. Here's the Landsat 5 Wikipedia article.
