Mars is a planet wide desert with underground and polar cap water, but it’s general arid environment and occasional wind give rise to dusty weather events such as tornado-like dust devils and local dust storms. Every so often, one of these little dust storms expands and becomes a planet wide phenomena, and in early June this is exactly what happened. So what does it mean for our rovers and orbiters? Global dust storms are a recurring phenomenon on Mars, and happen regularly about the planet regardless of season. Every 3-4 Martian years (6-8 Earth years) one of these smaller storms...
After an epic weekend of eclipse talk, NASA came out with a press conference that overshadowed much more than just the Moon. The announcement, as many had speculated, revealed that conclusive evidence shows there is flowing water on Mars. Like seasons on Earth, warmer conditions cause water to flow down steep hills and into valleys. The speculation came due to the invitation of Lujendra Ojha of the Georgia Institute of Technology to the NASA panel. Ojha noticed strange features on Mars as an undergraduate student in 2010, while looking at images from the Mars Reconnaissance Orbiter (MRO)’s High Resolution Imaging Science...
As the inevitable launch of humans to Mars slowly approaches over the coming decades, we are using our best technology to study our neighbour in detail. With multiple orbiting satellites and ground surveyors, we are slowly learning more about the geology, climate, environment, and history of Mars. It feels as if every new discovery is a surprise, and we never expected Mars to be such a dynamic and complex world. With science and technology improving every year, humanity is focussing efforts on the red planet. The latest incredible discovery comes from radar data from the Mars Reconnaissance Orbiter (MRO). The...
I couldn’t believe it when I read the story this morning. The Beagle 2 probe has been found, and partially intact even. It’s been more than eleven years since the 2003 Christmas day launch of Beagle 2 by the European Space Agency, presumed lost forever after months of attempts at establishing communication. Many scientists had assumed that Beagle 2 had smashed into Mars at high-velocity, destroying it completely, but photos from NASA’s Mars Reconnaissance Orbiter (MRO) clearly show the lander made it to the ground safely. The issue seems to be that the Beagle’s deployable ‘petals’ did not unfurl completely. The...
It’s true, Mars just had what we call a Meteor Storm. This is an event that, on Earth, only happens once every few hundred years, and the one that Mars just had was more intense than anything Earth has experienced in recorded history. This event happened because of a close Martian fly-by of comet C/2013 A1 Sliding Spring. On October 19th around 2:30pm EDT the comet came within 140,000 Km of Mars. This is incredibly close in Astronomical terms, being less than half the distance to the Moon and comparable to the total distance I’ve driven my car in the...
