[Monday, September 15, 2008] During the week of May 5-9, 2008, a key step on the path to Space-Based Solar Power was achieved: a "first-of-a-kind" long-range demonstration of solar-powered wireless power transmission.

[Monday, September 15, 2008] As of the first week of September 2008, Arctic sea ice extent had not fallen below the record low observed in 2007, but the season set a new kind of record.

[Monday, September 15, 2008] MDA announced today that it has been contracted to upgrade another remote sensing ground system for a confidential customer to receive and process RADARSAT-2 data.

[Monday, September 15, 2008] A long-standing scientific belief holds that stars tend to hang out in the same general part of a galaxy where they originally formed. Some astrophysicists have recently questioned whether that is true.

[Wednesday, September 17, 2008] NASA selected The Hammers Company, Greenbelt, Md., to build the Landsat Data Continuity Mission (LDCM) Mission Operations Element (MOE).

[Thursday, September 18, 2008] NASA will hold a media teleconference Tuesday, Sept. 23, at 12:30 p.m. EDT, to discuss data from the joint NASA and European Space Agency Ulysses mission that reveals the sun's solar wind is at a 50-year low.

[Saturday, September 20, 2008] "Satellite Observations to Benefit Science and Society: Recommended Missions for the Next Decade" brings the next ten years into focus for the Earth and environmental science community with a prioritized agenda.

[Sunday, September 21, 2008] NASA researchers have identified feasible emission scenarios that could keep carbon dioxide below levels that some scientists have called dangerous for climate.

[Sunday, September 21, 2008] Arctic sea ice coverage appears to have reached its lowest extent for the year and the second-lowest amount recorded since the dawn of the satellite era.

[Tuesday, September 23, 2008] Data from ESA/NASA Ulysses show that the Sun has reduced its output of solar wind to the lowest levels since accurate readings have become available. This current state of the Sun could reduce the natural shielding that envelops our Solar System.

[Tuesday, September 23, 2008] Some of the world's rarest and most precious metals could owe their presence in the Earth's crust to iron and stony-iron meteorites, fragments of a large number of asteroids that underwent significant geological processing in the early Solar System.

[Tuesday, September 23, 2008] For the past two years the Association of Space Explorers (ASE) -- the international organization of astronauts and cosmonauts from 34 countries -- has been developing a program to protect the Earth from asteroid impacts.

[Friday, September 26, 2008] After a two-year study involving a cast of international experts in government and science, ASE's Committee on Near-Earth Objects has completed a proposal to encourage the international community to set up procedures to protect the Earth.

[Friday, September 26, 2008] Tons of carbon molecules in dust particles and meteorites fall on Earth daily. Meteorites are especially valuable to astronomers because they provide relatively big chunks of carbon molecules that are easily analyzed in the laboratory.

[Friday, September 26, 2008] Scientists at the Carnegie Institution of Washington and McGill University in Montreal used geochemical methods to obtain an age of 4.28 billion years for samples of the rock, making it 250 million years more ancient than any previously discovered rocks.
