New NASA instrument for rapid hurricane response and marine forecasting

New NASA's mission to examine oceans winds

The International Space Station-Rapid Scatterometer (ISS-RapidScatt) was installed on 1 October 2014 as a means to improve the global monitoring of ocean winds.

NASA's latest Earth observing enterprise was activated to provide rapid response to weather and marine hazards. ISS-RapidScatt produces high-quality data that can be utilized to monitor wind speeds and directions. Within its very first days of operation, ISS-RapidScatt has gathered valuable data to effectively detect the development of the tropical cyclone Simon, which has been affecting the west coast of Mexico.

NASA: High-resolution topographic data soon available globally

Initially, topographic data for Africa will be published followed by Latin America and the Caribbean

The United States has announced that it will make high-resolution topographic data available globally in 2015. Previously, the data generated from NASA's Shuttle Radar Topography Mission (SRTM) in 2000 was only available in the US. The announcement was made at the United Nations Heads of State Climate Summit in New York.

Satellites capture exceptional 2014 floods in Bangladesh

The flooding has been particularly strong along the Brahmaputra River

Bangladesh is one of the most flood-prone countries in the world. However, a combination of heavy monsoon rainfall and the arrival of meltwater from the Himalayas has led to exceptionally heavy floods in Bangladesh in the summer of 2014. NASA's Terra satellite has captured a scene in late August showing flooded areas along the Brahmaputra River and the Tanquar hoar wetlands.

NASA: TRMM satellite moving towards end of mission

Artist Rendition of TRMM Satellite

On 8 July 2014, pressure sensors on board the Tropical Rainfall Measuring Mission’s (TRMM) satellite were triggered indicating the on board fuel tank to be near the end of its fuel supply.  The TRMM satellite was a joint mission between NASA and the Japan Aerospace Exploration Agency (JAXA) launched in 1997 making history carrying the world’s first precipitation radar payload into space with a planned 3 year mission to measure precipitation over the tropics.

ISS-RapidScat Mission set to begin in fall 2014

ISS-RapidScat scatterometer instrument

NASA’s International Space Station ISS-RapidScat scatterometer instrument platform is scheduled to be launched during the fall of 2014. It is designed to replace its predecessor QuickScat which has been in operation since 1999 on board the ISS. QuickScat collected and archived 400,000 measurements over 90 percent of the Earth’s surface on a daily basis. The data is used to calibrate measurements of other satellites.

Sweden: Unusually intense wildfires captured by satellite

This natural-color image of the fire in Sweden was captured by Landsat 8

Sweden is not a country typically known for its summer wildfires. Fires occur regularly, but not in the intesity of this year's blaze that has been affecting the region of Västmanland since 31 July 2014.

The fire grew to the largest one in 40 years. It has affected more than 150 square kilometers, killed one person and forced thousands to evacuate.

Using space technologies to study algal bloom

Algal bloom in the west end of Lake Erie captured by MODIS

Using a remote sensing technology that was originally developed for Mars exploration, NASA researchers are taking a closer look at algal bloom in Lake Erie in Northern America. Harmful toxic algal blooms can have a very negative impact on the environment, human health or the economy.

NASA: New robotic technology to fuel and fix orbiting satellites

The Remote Robotic Oxidizer Transfer Test, or RROxiTT

NASA's Satellite Servicing Capabilities Office (SSCO) at Goddard Space Flight Center in Maryland, in partnership with the Kennedy Space Center (KSC) in Florida, wants to create a robotic gas station in space to service with fuel the thousands of satellites currently orbiting Earth.

This would increase life expectancy of many satellites by puting off costly launches and slowing the rate of needed material sent into space.
