Current conservation approach

WWF’s current strategy for achieving its mission specifically focuses on restoring populations of 36 species (species or species groups that are important for their ecosystem or to people, including elephants, tunas, whales, dolphins and porpoises), and ecological footprint in 6 areas (carbon emissions, cropland, grazing land, fishing, forestry and water).

The organization also works on a number of global issues driving biodiversity loss and unsustainable use of natural resources, including
finance, business practices, laws, and consumption choices. Local offices also work on national or regional issues.

WWF works with a large number of different groups to achieve its goals, including other NGOs, governments, business, investment banks, scientists, fishers, farmers and local communities. It also undertakes public campaigns to influence decision makers, and seeks to educate people on how to live in a more environmentally friendly manner.

Notable programs and campaigns:

- Debt-for-Nature Swap;

- Earth Hour;

- Healthy Grown;

- Marine Stewardship Council;

- WWF global initiatives.

In 2008, through the Global Programme Framework (GPF), WWF is now focusing its efforts on 13 Global Initiatives:

- Amazon;

- Arctic;

- China for a Global Shif;

- Climate & Energy;

- Coastal East Africa;

- Coral Triangle;

- Forest and Climate;

- Green Heart of Africa;

- Heart of Borneo;

- Living Himalayas;

- Market Transformation;

- Smart Fishing;

- Tigers.

Mars Science Laboratory

Mars Science Laboratory (MSL) is a robotic space probe mission to Mars launched by NASA on November 26, 2011, which successfully landed Curiosity, a Mars rover, in Gale Crater on August 6, 2012. The overall objectives include investigating Mars' habitability, studying its climate and geology, and collecting data for a manned mission to Mars. The rover carries a variety of scientific instruments designed by an international team.

The Mars Science Laboratory mission is part of NASA’s Mars Exploration Program, a long-term effort for the robotic exploration of Mars that is managed by the Jet Propulsion Laboratory of California Institute of Technology. The total cost of the MSL project is about $2.5 billion.

NASA called for proposals for the rover’s scientific instruments in April 2004, and eight proposals were selected on December 14 of that year. Testing and design of components also began in late 2004, including Aerojet’s designing of a monopropellant engine with the ability to throttle from 15–100 percent thrust with a fixed propellant inlet pressure.

By November 2008 most hardware and software development was complete, and testing continued. At this point, cost overruns were approximately $400 million. In the attempts to meet the launch date, several instruments and a cache for samples were removed and other instruments and cameras were simplified to simplify testing and integration of the rover. The next month, NASA delayed the launch to late 2011 because of inadequate testing time. Eventually the costs for developing the rover did reach $2.47 billion, that for a rover that initially had been classified as
a medium-cost mission with a maximum budget of $650 million,
yet NASA still had to ask for an additional $82 million to meet the planned
November launch.

Between March 23–29, 2009, the general public ranked nine finalist rover names (Adventure, Amelia, Journey, Perception, Pursuit, Sunrise, Vision, Wonder, and Curiosity) through a public poll on the NASA website. On May 27, 2009, the winning name was announced to be Curiosity.

Previous successful U.S. Mars rovers include Spirit and Opportunity, and Sojourner from the Mars Pathfinder mission. Curiosity is about twice as long and five times as heavy as Spirit and Opportunity.

The MSL mission has four scientific goals: Determine the landing site's habitability including the role of water, the study of the climate and the geology of Mars. It is also useful preparation for a future manned mission to Mars.

To contribute to these goals, MSL has five main scientific objectives:

1. Determine the nature and inventory of organic carbon compounds.

2. Investigate the chemical building blocks of life (carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur).

3. Identify features that may represent the effects of biological pro-cesses.

4. Investigate the chemical, isotopic, and mineralogical composition of the Martian surface and near-surface geological materials.

5. Interpret the processes that have formed and modified rocks and soils.

As part of its exploration, it also measured the radiation exposure in the interior of the spacecraft as it traveled to Mars, and it is continuing radiation measurements as it explores the surface of Mars. This data would be important for a future manned mission.
