Martian gullies were in the spotlight last week thanks to a NASA press release stating they were "likely not formed by liquid water" based on spectral results. But how does this stack up against their morphology?
HiRISE Principal Investigator Alfred McEwen explains an imaging technique known as Super-Resolution Restoration (SRR), and how it could come in handy for high-resolution imaging of the Red Planet.
There have been tons and tons of HiRISE images of the Curiosity landing region, and it has taken quite a lot of work for me to find, locate, and catalogue them. This post is a summary of what I've found; after five revisions and updates, it's now version 3.0 of the list.
What's going on with our robotic planetary missions? In February I count more than 20 planetary spacecraft exploring six targets beyond Earth or cruising to new destinations.
NASA held a press briefing today to publicize a cool incremental result in the story of present-day liquid water on Mars. How big a deal is this story? Was all the pre-announcement hype justified? Is this just NASA discovering water on Mars for the zillionth time? What does this mean for things many space fans care about: life on Mars or future human exploration?
The Mars Reconnaissance Orbiter (MRO) Context Camera (CTX) is almost a silent star at Mars. The latest MRO data release brought the total number of available CTX images to over 70,000, covering well over 90% of the Red Planet at a stunning resolution of 6 meters per pixel.
I'm back from two weeks' vacation, so it's time to catch up on the status of all our intrepid planetary missions, from Akatsuki to the Voyagers and hitting the Moon, Mars, asteroids, comets, and Saturn in between.
There have been tons and tons of HiRISE images of the Curiosity landing region, and it has taken quite a lot of work for me to find, locate, and catalogue them. This post is a summary of what I've found; after four revisions and updates, it's now version 2.0 of the list.
It's been two weeks since comet Siding Spring passed close by Mars, and six of the seven Mars spacecraft have now checked in with quick looks at their images of the encounter. I round up all the results.
All seven Mars spacecraft are doing perfectly fine after comet Siding Spring's close encounter with Mars.
