China’s Chang’e 7 Will Include a Flag That Will ‘Flap’ on the Moon

China’s Chang’e 7 lunar lander mission will feature a flag fluttering in the vacuum of space. It’s one of the most often asked questions I get, while showing off the Moon to the public. “Can you see the flag the astronauts left there?” This then leads to a discussion on how far the Moon is, …

Archaeology On Mars: Preserving Artifacts of Our Expansion Into the Solar System

In 1971, the Soviet Mars 3 lander became the first spacecraft to land on Mars, though it only lasted a couple of minutes before failing. More than 50 years later, it’s still there at Terra Sirenum. The HiRISE camera NASA’s Mars Reconnaissance Orbiter may have imaged some of its hardware, inadvertently taking part in what …

China Plans to Retrieve Mars Samples by 2031

China’s growing presence in space has been undeniable since the turn of the century. Between sending the first “taikonaut” to space in 2003 (Yang Liwei), launching the first Chinese robotic mission to the Moon (Chang’e-1) in 2007, and the deployment of their Tiangong space station between 2021-2022, China has emerged as a major power in …

China Will Launch its Mars Sample Return Mission in 2028

While NASA’s Mars Sample Return mission has experienced a setback, China is still moving forward with their plans to bring home a piece of the Red Planet. This week, officials from the China National Space Administration (CNSA) announced their sample return mission, called Tianwen-3, will blast off for Mars in 2028. It will land on …

There are Mysterious Polygons Beneath the Surface of Mars

China’s Zhurong rover was equipped with a ground-penetrating radar system, allowing it to peer beneath Mars’s surface. Researchers have announced new results from the scans of Zhurong’s landing site in Utopia Planitia, saying they identified irregular polygonal wedges located at a depth of about 35 meters all along the robot’s journey. The objects measure from …

What’s Going on With the Mars Sample Return Mission?

Anybody with a modicum of intellectual curiosity is looking forward to the NASA/ESA Mars Sample Return Mission. NASA’s Perseverance rover is busily collecting and caching samples for eventual return to Earth. While the technical and engineering challenges in getting those samples into scientists’ hands here on Earth are formidable, budgeting and funding might be the …

A Robotic Chemist Could Whip up the Perfect Batch of Oxygen on Mars

Humans on Mars will need oxygen, and Mars’ atmosphere is pretty anemic when it comes to the life-sustaining element. NASA’s Perseverance rover successfully extracted oxygen from CO2 in Mars’ atmosphere, but there are other ways to acquire it. There seem to be vast amounts of water buried under the Martian surface, and oxygen in the …
