The truth is that only the United States has had the knowledge and moxie to successfully land a vehicle on Mars. We have now done it seven times, and no other nation has really come particularly close. And with the touchdown of the one-ton and highly sophisticated Curiosity, the U.S. has reached a whole new […]
PASADENA, Calif. — About 34 hours from the Mars rover Curiosity’s landing (scheduled for 01:31 am Eastern time on Monday), NASA brought us the latest weather forecast from the surface — dry and cold, with a slight chance of dust. Slight is good. Earlier this week, the Mars Reconnaissance Orbiter spotted a dust storm south […]
[CLICK ON IMAGE for high resolution. Credit: Cristian Fattinnanzi] Skygazers around planet Earth enjoyed the close encounter of planets and Moon in July 15’s predawn skies. And while many saw bright Jupiter next to the slender, waning crescent, Europeans also had the opportunity to watch the ruling gas giant pass behind the lunar disk, occulted […]
What created this unusual hole in Mars? The hole was discovered by chance on images of the dusty slopes of Mars’ Pavonis Mons volcano taken by the HiRISE instrument aboard the robotic Mars Reconnaissance Orbiter currently circling Mars. The hole appears to be an opening to an underground cavern, partly illuminated on the image. Analysis […]
[CLICK ON IMAGE TO ZOOM] Early morning dog walkers got a visual treat last week as bright stars and planets appeared to line up. Pictured above, easily visible from left to right, were the Pleiades open star cluster, Jupiter, Venus, and the “Follower” star Aldebaran, all seen before a starry background. The image was taken […]
[SEE HIGH RES IMAGE] A quintet of Saturn’s moons come together in the Cassini spacecraft’s field of view for this portrait. Janus (179 kilometers, or 111 miles across) is on the far left. Pandora (81 kilometers, or 50 miles across) orbits between the A ring and the thin F ring near the middle of the […]
Click here for high-resolution image. From fresh rover tracks to an impact crater blasted billions of years ago, a newly completed view from the panoramic camera on NASA’s Mars Exploration Rover Opportunity shows the ruddy terrain where the voyaging robot spent the Martian winter. This scene, recorded from the mast-mounted color camera includes the rover’s […]
Humanity’s robot orbiting Saturn has recorded yet another amazing view. That robot, of course, is the spacecraft Cassini, while the new amazing view includes a bright moon, thin rings, oddly broken clouds, and warped shadows. Titan, Saturn’s largest moon, appears above as a featureless tan as it is continually shrouded in thick clouds. The rings […]
As its June 6 2012 transit begins Earth’s sister planet crosses the edge of the Sun in this stunning view from the Hinode spacecraft. The timing of limb crossings during the rare transits was used historically to triangulate the distance to Venus and determine a value for the Earth-Sun distance called the astronomical unit. … […]
This dramatic telephoto view across the Black Sea on June 6 finds Venus rising with the Sun, the planet in silhouette against a ruddy and ragged solar disk. Of course, the reddened light is due to scattering in planet Earth’s atmosphere and the rare transit of Venus didn’t influence the strangely shaped and distorted Sun. […]
