Comet Catalina Tails

Explanation: A new year's treat for binoculars, as 2016 begins Comet Catalina (C/2013 US10) now sweeps through planet Earth's predawn skies near bright Arcturus, alpha star of Bootes. But this telescopicmosaic from December 21 follows the pretty tails of the comet across a field of view as wide as 10 full moons. The smattering of distant galaxies and faint stars in the background are in the constellation Virgo. Trailing behind the comet's orbit, Catalina's dust tail fans out below and left in the frame. Its ion tail is angled toward the top right, away from the Sun and buffeted by the solar wind. On January 17, the outward bound visitor from the Oort Cloud will make its closest approach to Earth, a mere 110 million kilometers away, seen near bright stars along the handle of the Big Dipper.

Jason-3, due for launch on 17 January 2016, will secure the continuity of high quality ocean altimetry measurements in support of climate monitoring, operational oceanography and seasonal forecasting.

This service, currently provided by the ageing Jason-2, provides measurements of sea surface height, wind speed at the ocean surface and sea state.

Highly accurate measurements of sea surface height are vital for monitoring mean sea level in our changing climate. They are also used in ocean forecasting models for operational oceanography, and for ocean-atmosphere models used for “seasonal forecasting”, i.e. to predict the likelihood of intense cyclonic seasons in the tropics, or a mild winter in the mid-latitudes.

Jason-3 is the result of an international partnership between EUMETSAT, the French Space Agency (CNES), the US National Oceanic and Atmospheric Administration (NOAA) and the US National Aeronautics and Space Administration (NASA). In addition, the European Union will fund operations of the Jason-3 satellite as a precursor to the future Copernicus Sentinel-6/Jason-CS mission and as the reference mission for Sentinel-3.

On this website, you can follow the campaign to launch and commission the satellite. Here you will find the latest news, images and video of the launch campaign, including a link to the video transmission of the launch itself from Vandenberg AFB in California.

Nasa pulls the plug on killer asteroid hunter: Sentinel mission set up to search for dangerous space rocks loses $30 million support

The Near-Earth Object Camera (NEOCam) is a new mission proposal designed to discover and characterize most of the potentially hazardous asteroids that are near the Earth. NEOCam consists of an infrared telescope and a wide-field camera operating at thermal infrared wavelengths.

Há muito que é aguardado. Inicialmente, estava agendado para 22 de Julho de 2015. Espera-se que a aterragem do foguetão venha a ser concretizada sobre uma plataforma flutuante no oceano.

No dia 4 de Fevereiro será o lançamento o Sentinel-3A da Estação Espacial Europeia (ESA) que também vai observar os oceanos.
