Last Up-close Look at Hyperion
NASA's Cassini spacecraft will make its final close approach to Saturn's large, irregularly shaped moon Hyperion on Sunday, May 31. The Saturn-orbiting spacecraft will pass Hyperion at a distance of about 21,000 miles (34,000 kilometers) at approximately 6:36 a.m. PDT (9:36 a.m. EDT). Mission controllers expect images from the encounter to arrive on Earth within 24 to 48 hours.
WhaleWatch is a new NOAA computer program that uses NASA and other satellite data to predict the movements of four whale species, including blue whales. Funded by the NASA Applied Sciences Program, the tool was created to help decrease whale deaths due to collisions with ships and fishing gear. #EarthRightNow
Mars is a busy place
This graphic depicts the relative shapes and distances from Mars for five active orbiter missions plus the planet's two natural satellites. It illustrates the potential for intersections of the spacecraft orbits. An enhanced process of traffic monitoring, communication and maneuver planning ensures that Mars orbiters won't approach each other too closely. Read more…
Climate Time Machine
A new series of visualizations demonstrate how some of Earth's key climate indicators are changing over time.
Spot The Station
NASA’s Spot The Station service gives you a list of upcoming sighting opportunities for thousands of locations worldwide and will let you sign up to receive notices. The space station looks like a fast-moving plane in the sky, but it is dozens of times higher than any airplane and traveling thousands of miles an hour faster. It is bright enough that it can even be seen from the middle of a city!
