Canada is building the world's first space telescope designed to detect and track asteroids as well as satellites. Called NEOSSat, this spacecraft will provide a significant improvement in surveillance of asteroids that pose a collision hazard with Earth and innovative technologies for tracking satellites in orbit high above our planet.

NASA's Phoenix Mars Lander placed a sample of Martian soil in the spacecraft's wet chemistry laboratory June 25 for the first time. Results from that instrument, part of Phoenix's Microscopy, Electrochemistry and Conductivity Analyzer, are expected to provide the first measurement of the acidity or alkalinity of the planet's soil.

A new analysis of Martian soil data suggests that there was once enough water in the planet's atmosphere for dew to hit the ground, leaving tell-tale signs of its interaction with the planet's surface. The study's conclusion breaks from the more dominant view that the liquid water that once existed during the red planet's infancy came mainly in the form of upwelling groundwater.
