Comet C/2013 A1 Siding Spring will make a close flyby of Mars on Oct. 19, 2014. At a distance of only 87,000 miles – about 1/3 the distance between the Earth and moon - it's a near miss of the Red Planet. Find out how NASA’s Mars orbiters will evade dust from the comet.

Time-lapse footage of the RapidScat "wind watcher" instrument being installed on the International Space Station, followed by reaction by the team after its activation.

What's Up for October? A lunar eclipse, a solar eclipse and Mars has a close encounter with a comet.

NASA's Curiosity Mars rover has collected its first sample from the base of Mount Sharp. The scientific allure of the layered mountain drew the team to choose this part of Mars as a landing site.

After 2 years and nearly 9 kilometers of driving, NASA's Mars Curiosity has arrived at the base of Mount Sharp.

ISS-RapidScat will collect data on ocean winds to support weather and marine forecasting including tracking storms and hurricanes and aid climate research. It is the first Earth-observing instrument designed to mount on the International Space Station. The station's unique orbit will enable ISS-RapidScat to make the first observations of how ocean winds vary over the course of the day, vital information for improving the accuracy of all satellite wind measurements.
