Scientists at NASA’s Jet Propulsion Laboratory were jubilant last night, letting out a long whoop, following word of the picture-perfect descent and landing of the new Mars rover, Curiosity. The descent of the rover from the top of Mars’ atmosphere to the planet’s surface had earlier been called seven minutes of terror by these scientists, because of its extreme difficulty and zero margin for error. The safe landing of Curiosity marks the beginning what promises to be the most ambitious planetary missions in history. Mission mechanical system lead Adam Stelzner said:
It looks extremely clean. We touched down in conditions that were on the more benign side of our nominal expectations. It looks – at least by my eye – like we landed in a nice flat spot. Beautiful. Really beautiful.
The Curiosity rover will be able to travel at speeds of up to 90 meters (0.06 miles) per hour, though it is expected to travel at a slower average of about 30 meters per hour. The rover can roll over obstacles up to 75 centimeters (30 inches) high.
Bottom line: NASA’s Mars Curiosity rover has landed safely on Mars.
Deborah Byrd created the EarthSky radio series in 1991 and founded EarthSky.org in 1994. Today, she serves as Editor-in-Chief of this website. She has won a galaxy of awards from the broadcasting and science communities, including having an asteroid named 3505 Byrd in her honor. A science communicator and educator since 1976, Byrd believes in science as a force for good in the world and a vital tool for the 21st century. "Being an EarthSky editor is like hosting a big global party for cool nature-lovers," she says.
