  • Canadian satellite system under budget cloud

    Canadian satellite system under budget cloud

    Nature

    Missed deadlines and an underfunded Canada Space Agency (CSA) may scuttle plans to build the next generation of earth observing satellites, according to the Canadian satellite company pegged to build them.

    In 2010, the CSA selected MacDonald, Detwillier and Associates Ltd. to design the successor to Radarsat-2, the agency’s current earth observing satellite. The company came up with a three-satellite system that would provide information for maritime surveillance, disaster management and ecosystem monitoring. But Dan Friedman, the company’s president and chief executive officer, says the federal government missed a target deadline for awarding the building contract in January, according to a story in the Globe and Mail and the CSA may not have enough money for the project.

    The Radarsat Constellation calls for three satellites (scalable to six) to maintain a polar orbit and provide radar images of nearly all of Canada’s land and waters. The Constellation would monitor ice and icebergs, winds and oil pollution in shipping lanes and coastal zones on a daily basis. It would also provide information on the state of Canada’s forests, changes to vegetation in protected areas and important wildlife habitat, and monitor wetlands and coastal change.  Unlike Radarsat-2, which is owned by MDA, the Canadian government would own Constellation.

    Canada’s Earth observing satellites, Radarsat-1 and -2, have been important in mapping natural disasters, such as the 2011 flooding in Queensland, Australia, as well as the Antarctic’s glaciers and ice sheets. including a subsurface view of the ice-covered Lake Vostok.

  • Canadian budget bill undermines environment, critics charge

    Today in Canada’s House of Commons,  lawmakers debated a budget bill that critics say would gut a variety of environmental and species protection measures.

    The Jobs, Growth and Long-term Prosperity Act would allow the Conservative-led government to implement certain provisions included in the 2012 budget tabled just over a month ago (see ‘Canadian budget hits basic science‘). But the 420-page document includes “other measures,” which have angered the opposition, environmental groups and scientists.

    Bill C-38 aims to repeal the current Canadian Environmental Assessment Act, a federal law that promotes sustainable development, and rewrites the role of the National Energy Board, an independent agency that regulates the construction and operation of oil and natural gas pipelines that traverse provincial or international borders. The bill also relieves Canada from its duties under the Kyoto Protocol Implementation Act.

    The government says changes to the CEAA and NEB are necessary to streamline the environmental assessment process, make sure projects are reviewed in a timely manner and reduce duplicate assessments.

    The changes to the NEB would limit project reviews to two years, in an effort to avoid a repeat of the six-year review of the 1,200-kilometre long Mackenzie Valley natural gas pipeline that was finally approved in 2010. It would also give cabinet the final say on whether a project is approved. “In the past, there wasn’t a direct provision for the cabinet to overrule the decision and send it back for further review,” says Andrew Leach, an environmental economist at the University of Alberta, in Edmonton.
