What has the Opportunity rover found on Mars? While traversing a vast empty plain in Meridiani Planum, one of Earth's yearling rolling robots found a surprise when visiting the location of it own metallic heat shield discarded last year during descent.
Looking Out Over Mars
23.08.2004
What would it be like to climb a hill and look out over Mars? That opportunity was afforded the Spirit rover earlier this month as it rolled to a high perch in the Columbia Hills.
Mosaic of Endurance Crater on Mars
11.10.2004
Where should this Martian rover explore next? Possible choices for the Opportunity rover team on Earth in early August were to send the Martian robot inside Endurance crater toward the arc-shaped sand dunes...
Rolling Across the Rocky Plains of Mars
4.10.2010
You stare out across the rocky plains of Mars. Before you, in every direction, is dark sand and bright rock. Although little has changed here for millions of years, no one has ever seen this view before. You are being sent on a long journey to a distant crater, the largest crater in the region.
An Ancient Stream Bank on Mars
2.10.2012
Fresh evidence of an ancient stream has been found on Mars. The robotic rover Curiosity has run across unusual surface features that carry a strong resemblance to stream banks on Earth. Visible in the above image, for example, is a small overhanging rock ledge that was quite possibly created by water erosion beneath.
Asteroids in the Distance
31.01.2021
Rocks from space hit Earth every day. The larger the rock, though, the less often Earth is struck. Many kilograms of space dust pitter to Earth daily. Larger bits appear initially as a bright meteor. Baseball-sized rocks and ice-balls streak through our atmosphere daily, most evaporating quickly to nothing.
A Giant Gouge on Asteroid Eros
21.02.2000
Asteroid 433 Eros is posing several riddles. NASA's robot spacecraft NEAR began orbiting the 30-kilometer space rock last week, and new pictures are now being beamed back to Earth regularly. As usual in science, when you arrive at a place you've never been before, you see things you don't immediately understand.
18 Miles From Deimos
22.12.1996
Diminutive Deimos is the smallest of the two tiny Moons of Mars. Potato shaped and barely 6 miles wide this asteroid-like body was visited by the Viking 2 orbiter in 1977. This image was made when the spacecraft approached to within 18 miles of Deimos' surface.
Rover Arrives at Endeavor Crater on Mars
15.08.2011
What can the present-day terrain in and around large Endeavor crater tell us about ancient Mars? Starting three years ago, NASA sent a coffee-table sized robot named Opportunity on a mission rolling across the red planet's Meridiani Planum to find out. Last week, it finally arrived.
Metal on the Plains of Mars
31.07.2011
What has the Opportunity rover found on Mars? While traversing a vast empty plain in 2005 in Meridiani Planum, one of Earth's rolling robots on Mars found a surprise when visiting the location of its own metallic heat shield discarded last year during descent.
