New Horizons' Data of Pluto/Charon Show Rarity of Small Kuiper Belt Objects

Pluto’s largest moon, Charon, as seen by New Horizons in 2015. The lack of smaller craters -less than expected – suggests that small objects less than a mile in size are rare in the Kuiper Belt. Photo Credit: NASA/JHUAPL/SwRI/Alex Parker

The Kuiper Belt is a vast region of rocky debris in the outer Solar […]

NASA’s Opportunity rover has now been on Mars for an incredible 15 years since its landing in […]

'Could Not Have Survived': 20 Years Since NASA's Ill-Fated Mars Polar Lander

Mars Polar Lander was targeted for touchdown close to the south pole of the Red Planet for detailed inspection of its terrain, past and present climatic conditions and weather. Its failure severely jeopardized NASA’s plans of exploring the planet. Image Credit: NASA

Twenty years ago, this week, the familiar high-pitched scream of a Delta […]
