ACE+ is the response to ESA´s 2nd Call for Earth Explorer Opportunity Missions in 2001. ACE+ will considerably advance our knowledge about atmosphere physics and climate change processes. The mission will demonstrate a highly innovative approach using radio occultations for globally measuring profiles of humidity and temperature throughout the atmosphere and stratosphere.
In the presence of the Minister of Commerce, Odd Eriksen, the Norwegian User Support and Operations Centre (N-USOC) at Plantebiosenteret (located at The Norwegian University of Science and Technology (NTNU) in Trondheim, Norway) was opened on March 31, 2006.
A plant experiment proposed by a scientific group at the Department of Physics and one at the Department of Biology (Plantebiosenteret) using the model plant Arabidopsis thaliana has been selected as the first Norwegian biological experiment on the ISS.
Keeping the astronauts in good physical shape.
Increasing possibilities for microgravity research
On February 1 2003 the American space shuttle Columbia disintegrated during reenty, killing all seven astronauts on board and bringing the shuttle program to a halt.
Through the development of the Ørsted satellite, and the use of data from him, Denmark has appropriated valuable experience in using satellites in different ways. That has led to several proposals for new missions.
During the last 30 years a global network of stations equipped with instruments for high precision observation of artificial Earth satellites and very distant radio sources has been established. Some of the satellites are carrying payloads, for example radar altimeters, where the application requires that the radial component of the satellite orbit must be determined to a precision of five cm or better.
