Excellent launch precision for NASA’s Mars Science Laboratory mission has forestalled the need for an early trajectory correction maneuver, now not required for a month or more. That first of six planned course adjustments during the 254-day journey from Earth to Mars had originally been scheduled for 15 days after… Continue reading
After spending more than 240 days “sailing” around Earth, NASA’s NanoSail-D — a nanosatellite that deployed NASA’s first-ever solar sail in low-Earth orbit — has successfully completed its Earth orbiting mission. Continue reading
The youngest planet yet discovered has been found orbiting within the disk of dust and gas surrounding the star Lk Ca 15. The planet is more than just young: it may still be in the process of formation. Continue reading
The retirement of the space shuttle has sparked a debate about the value of human spaceflight. Some see it as a waste of resources. Robots are better, cheaper alternatives, they say – and robotic missions don’t risk human lives. Others see the ability to fly humans into space as being tied up with national prestige, influence, and soft power. Continue reading
This animation depicts the artist’s vision of the key events of the future NASA’s Mars Science Laboratory mission. It is planned to launch in late 2011 and reach Mars in August 2012. The rover will be called “Curiosity”. Continue reading
