Tomorrow, one way or another, the ESA’s Rosetta mission is coming to an end. In a final maneuver, the craft will attempt to land on the surface of the comet, following in the footsteps of the Philae lander, though hopefully with more success. The video shows the final orbit plan, and really highlights how amazing mission scientists are to be able to plan a landing site when the comet is rotating so quickly, relative to the craft’s motion. You can follow the link to watch the live broadcast of the event here. The mission will end around 7:20am EST tomorrow,...
It’s always funny explaining astronomical time to a non-scientist. I often get the craziest looks when I mention a million years as being a ‘blip on the radar.’ Perhaps there is some immortal alien race out there who would understand how nothing much happens on the scale of the universe in a million years. To humanity and our ever-accelerating advancement, a million years is thrice the age of our entire species. But I guess Einstein was right when he said that ‘it’s all relative.’ This brings us to Saturn, a planet as ancient as the solar system. Moderately old in...
This week marks the 12 year anniversary of the Spirit and Opportunity rovers, part of the Mars Exploration Rover (MER) mission. Only expected to last 90 days, Opportunity is still working. Not only functional, it’s still returning good data about Mars. It’s definitely taken a beating, and it has to be careful. Being powered by solar panels and not a thermonuclear generator like it’s younger cousin Curiosity means it has to be careful to stay in the sunlight. Dust on the panels certainly reduces their efficiency, but Opportunity has had some help from Martian winds to keep the dust from...
A few years ago, in a desert in Morocco, a very special meteorite was found. A rock unlike anything ever found on Earth, called NWA 7034, or colloquially ‘black beauty.’ Chemical analysis in 2011 found that it originated on Mars, but it was even unlike any other Martian meteorite discovered. The scientific community was extremely excited to determine its properties through a spectroscopic analysis, and today we have some answers that are as amazing as we expected. A new paper detailing spectroscopic results of the meteorite reveal that its composition is the same as the composition of the dark Martian...
I was blown away to hear this news just a few hours after the launch. The Antares rocket exploded on the launchpad just six seconds after launch. Yesterday’s post discussed how the Antares-Cygnus resupply launch was delayed by a lone man in a boat who had no clue he was in the blast zone. First of all, it’s important to note that no one was hurt, including all personnel on site and in the control room. This was an unmanned rocket, so the major loss was the resupply capsule and its cargo, not to mention the loss of the $250...
One of the funnier parts of the scientific method, at least during work in the field, is that nature is a cruel prankster. The smallest things can derail the greatest of experiments. More often than not this results in catastrophe, yet some of the greatest leaps in Science have come from something that seemingly went wrong. Alexander Fleming accidentally discovered penicillin when he noticed that a bacterial culture had been contaminated with mold, but the bacteria did not spread anywhere near the mold. Penzias and Wilson discovered the Cosmic Microwave Background Radiation when they were trying to detect faint radio waves...
