NASA's Rover mission: Magnificent 7 years on the Planet Mars

While NASA's Spirit rover is frozen in place on Mars and potentially dead to the world, the Opportunity rover is hale and hearty as it begins its eighth year of operation on the Red Planet.
"Seven years is a long time, but we're all delighting in it," John Callas, project manager for the rover missions at NASA's Jet Propulsion Laboratory, told me today.


History:


NASA's Mars Exploration Rover Mission (MER) is an ongoing robotic space mission involving two rovers, Spirit and Opportunity, exploring the planet Mars. It began in 2003 with the sending of the two rovers — MER-A Spirit and MER-B Opportunity — to explore the Martian surface and geology.

Objectives of Rover Mission on Mars:

The scientific objectives of the Mars Exploration Rover mission are to:[7]
  • Search for and characterize a variety of rocks and soils that hold clues to past water activity. In particular, samples sought include those that have minerals deposited by water-related processes such as precipitation, evaporation, sedimentary cementation, or hydrothermal activity.
  • Determine the distribution and composition of minerals, rocks, and soils surrounding the landing sites.
  • Determine what geologic processes have shaped the local terrain and influenced the chemistry. Such processes could include water or wind erosion, sedimentation, hydrothermal mechanisms, volcanism, and cratering.
  • Perform calibration and validation of surface observations made by Mars Reconnaissance Orbiter instruments. This will help determine the accuracy and effectiveness of various instruments that survey Martian geology from orbit.
  • Search for iron-containing minerals, and to identify and quantify relative amounts of specific mineral types that contain water or were formed in water, such as iron-bearing carbonates.
  • Characterize the mineralogy and textures of rocks and soils to determine the processes that created them.
  • Search for geological clues to the environmental conditions that existed when liquid water was present.
  • Assess whether those environments were conducive to life.

Printing from ur Smartphone...??.Google Cloud Printing on the go..!

Last year Google announced Google Cloud Print, a service that in Beta allows printing from any app on any device, OS or browser without the need to install any software. Just last month we opened Google Cloud Print to users in the Chrome notebook pilot program. Today we are very pleased to announce the beta launch of Google Cloud Print for mobile documents and Gmail for mobile, which we will be rolling out to users throughout the next few days.

Imagine printing an important document from your smartphone on the way to work and finding the printout waiting for you when you walk in the door. Just open a document in Google Docs or an email in Gmail in your mobile browser and choose “Print” from the dropdown menu in the top right corner. You can also print certain kinds of email attachments (such as .pdf or .doc) by clicking the “Print” link that appears next to them.


This feature will be rolling out today and tomorrow for English speaking users in the US and will work on most phones that support HTML5, such as devices running Android 2.1+ and iOS 3+. To get started, you’ll need to connect your printer to Google Cloud Print. This step requires a Windows PC for now, but Linux and Mac support are coming soon. You can learn more at the Google Cloud Print help center.


Happy printing!

Mind blowing Facts...Whoa !

1. Sound is sent from the radio station through the air to your radio by means of electromagnetic waves. News, music, Bible teaching, baseball games, plays, advertisements- these sounds are all converted into electromagnetic waves (radio waves) before they reach your radio and your ears.
2. At the radio station, the announcer speaks into a microphone. The microphone changes the sound of his voice into an electrical signal. This signal is weak and can't travel very far, so it's sent to a transmitter. The transmitter mixes the signal with some strong radio signals called carrier waves. These waves are
then sent out through a special antenna at the speed of light! They reach the antenna of your radio. Your antenna "catches" the signal, and the radio's
amplifier strengthens the signal and sends it to the speakers. The speakers vibrate, and your ears pick up the vibrations and your brain translates them into
the voice of the radio announcer back at the station. When you consider all the places the announcer's voice travels
3. Every radio station has its own frequency. When you turn the tuning knob on your radio, you are choosing which frequency you want your antenna to "catch."

4. Mountain lions are known by more than 100 names, including panther, catamount, cougar, painter and puma. It's scientific name is Felis concolor, which means "cat of one color." At one time, mountain lions were very common!

6. They can jump a distance of 30 feet, and jump as high as 15 feet. It would take quite a fence to keep a mountain lion out!
7. Their favorite food is deer, but they'll eat other critters as well. They hunt alone, not in packs like wolves. They sneak up on their prey just like a house cat sneaks up on a bird or toy- one slow step at a time. A lion can eat ten pounds of meat at one time! That's equivalent to 40 quarter-pounder hamburgers!
