In Roman mythology Mercury was the “Messenger of the Gods,” — as well as a god of trade, thieves and travel. It is thus fitting — apart from the trade and thieves aspect — that the MESSENGER program has been so carefully studying the inner most planet in our solar system. MErcury, Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) this week successfully completed a year-long mission to perform the first complete reconnaissance of the...

On March 17, 2012, MESSENGER successfully wrapped up a year-long campaign to perform the first complete reconnaissance of the geochemistry, geophysics, geologic history, atmosphere, magnetosphere, and plasma environment of the solar system's innermost planet. The following day, March 18, 2012, marked the official start of an extended phase designed to build upon those discoveries. What MESSENGER has accomplished since its launch in August 2004 is "amazing," says MESSENGER Mission Systems...

Data collected during MESSENGER's third through sixth month in orbit around Mercury were released to the public today by the Planetary Data System (PDS), an organization that archives and distributes all of NASA's planetary mission data. With this release, data are now available to the public for the first full Mercury solar day of MESSENGER orbital operations. Calibrated data from all seven of MESSENGER's science instruments, plus radio science data from the spacecraft telecommunications...

MESSENGER successfully completed an orbit-correction maneuver on March 2 to lower its periapsis altitude - the lowest point of MESSENGER's orbit about Mercury relative to the planet's surface - from 405 to 200 kilometers (251 to 124 miles). This is the first of three planned maneuvers designed to modify the spacecraft's orbit around Mercury as science operations transition from MESSENGER's primary orbital mission to its extended mission. MESSENGER's orbit around Mercury is highly...

Transcriptional elongation control takes on new dimensions as Stowers researchers find gene class-specific elongation factors Life is complicated enough, so you can forgive the pioneers of DNA biology for glossing over transcriptional elongation control by RNA polymerase II, the quick and seemingly bulletproof penultimate step in the process that copies the information encoded in our DNA into protein-making instructions carried by messenger RNA. In a new report appearing in the Dec. 23,...

The Planet Mercury -- in astronomy, nearest planet to the sun, at a mean distance of 36 million mi (58 million km); its period of revolution is 88 days. Mercury passes through phases similar to those of the moon as it completes each revolution about the sun, although the visible disk varies in size with respect to its distance from the earth. Because its greatest elongation is 28, it is seen only for a short time after sunset or before sunrise. Since observation of Mercury is...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
