Perhaps the largest challenge of our society is to find ways to replace the slowly but inevitably vanishing fossil fuel supplied by renewable resources and, at the same time, avoid negative effects from the current energy system on climate, environment and health. The quality of human life is to a large degree depends upon the availability of clean energy sources. The worldwide power consumption is expected to double in the next 3 decades because of the increase in world population and the rising demand of energy in the developing countries.

Journey to the Moon PART-1

“But why, some say, the Moon? Why choose this as our goal? And they may well ask why climb the highest mountain? Why, 35 years ago, fly the Atlantic? We choose to go to the Moon. We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills; because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win.”

-John F. Kennedy

Human beings have been historically curious about their surroundings and the mystery of the cosmos. Man has always wanted to discover new land and colonies these lands.  One of man’s main amazement has been the moon. For centuries, Man was successful in colonising different parts of earth. But moon looked like an impossible dream for mankind. That was until the American government decided that it was time to send man to moon. Read more »

Cassini Orbiter Instrument IV – The VIMS

The Visual and Infrared Mapping Spectrometer (VIMS) is a pair of imaging grating spectrometers. It is able to identify the chemical composition of a surface, atmosphere, or Saturn’s rings by measuring the visible and infrared energy. VIMS is  in essence, a color camera that takes pictures in 352 different wavelengths between 300 nm and 5100 nm. This range, coupled with the ability to discern different wavelengths (called spectral resolution), allows the VIMS instrument to be able to very accurately quantify the light it detects. These data are used by the team members to carry out many different multidisciplinary investigations.

VIMS Scientific Objectives:

  • To map the temporal behavior of winds, eddies, and other features on Saturn/Titan.
  • To study the composition and distribution of atmospheric and cloud species on Saturn/Titan.
  • To determine the composition and distribution of the icy satellite surface materials.
  • To determine temperatures, internal structure, and rotation of Saturn’s deep atmosphere.
  • To study the structure and composition of Saturn’s rings.
  • To search for lightning on Saturn and Titan and for active volcanism on Titan.
  • To observe Titan’s surface.

 This high-resolution infrared image was taken during the Cassini spacecraft’s closest approach to Titan on Oct. 26, 2004. These images were obtained by Cassini’s visual and infrared mapping spectrometer instrument and show a bright, circular feature (8.5 degree latitude, minus 143.5 degree longitude) with two elongated wings extending westwards. Scientists think this feature might be a volcano.

The process includes the work of scientists from all over the world, technical employees at the University of Arizona (UofA) and the Jet Propulsion Laboratory (JPL), and science planners at the JPL to name a few of the key participants.

UVIS Instrument

Cassini Orbiter Instrument III – The UVIS

 UVIS – The Ultraviolet Imaging Spectrograph, is one of the 12 instruments installed on board Cassini. It was built by the   Laboratory for Atmospheric and Space Physics (LASP) located in the Research Park of the University of Colorado in Boulder.

UVIS is a set of telescopes used to measure ultraviolet light from the Saturn system’s atmospheres, rings, and surfaces. The UVIS will also observe the fluctuations of starlight and sunlight as the sun and stars move behind the rings and the atmospheres of Titan and Saturn, and it will determine the atmospheric concentrations of hydrogen and deuterium.

Journey to the Moon PART-2

“That’s one small step for man, one giant leap for mankind.”
-Neil Armstrong

Finally, U.S president John Kennedy’s dream had come true. Apollo 11 was all set to take man to the moon.  Millions of dollars were spent. Thousands had sacrificed their sweat and blood into making this project a success.                           Apollo 11 had on board the greatest and most skillful astronauts on earth.

The Crew consisted of:

The Apollo 11 crew.

  1. Neil Armstrong.
  2. Michael Collins
  3. Edwin “Buzz” E. Aldrin

LAUNCH:
A Saturn V launched Apollo 11 at the Kennedy Space Center on July 16, 1969 at 13:32:00 UTC. It entered orbit 12 minutes later. On July 20, 1969 the lunar module (LM) Eagle separated from the command module Columbia. As the descent began, Armstrong and Aldrin found that they were passing landmarks on the surface 4 seconds early and reported that they were “long”. They would land miles west of their target point.

Saturn V launching Apollo 11

LANDING:
When Armstrong  looked outside, he saw that the computer’s landing target was in a boulder-strewn area just north and east of a 300 metres (980 ft.) diameter crater (later determined to be “West crater”, named for its location in the western part of the originally planned landing ellipse). Armstrong took semi-automatic control. Apollo 11 landed with less fuel than other missions, and the astronauts also encountered a premature low fuel warning. This was later found to have been due to greater propellant ‘slosh’ than expected, uncovering a fuel sensor.

First Moon Walk:

Although the official NASA flight plan called for a crew rest period before extra-vehicular activity, Armstrong requested that the EVA be started sooner. Once Armstrong and Aldrin were ready to go outside, Eagle was depressurized, the hatch was opened and Armstrong made his way down the ladder first. Armstrong then turned and set his left boot on the surface at 2:56 UTC July 21, 1969, then spoke the famous words “That’s one small step for man, one giant leap for mankind.”

Armstrong had decided on this statement following a train of thought that he had after launch and during the hours after landing. About 20 minutes after the first step, Aldrin joined Armstrong on the surface and became the second human to set foot on the Moon, and the duo began their tasks of investigating how easily a person could operate on the lunar surface. Early on they also unveiled a plaque commemorating their flight, and also planted the flag of the United States. The flag used on this mission had a metal rod to hold it horizontal from its pole. Since the rod did not fully extend, and the flag was tightly folded and packed during the journey, the flag ended up with a slightly wavy appearance, as if there were a breeze.

In the entire Apollo 11 photographic record, there are only five images of Armstrong partly shown or reflected. The mission was planned to the minute, with the majority of photographic tasks to be performed by Armstrong with their single camera. Armstrong’s final task was to leave a small package of memorial items to deceased Soviet cosmonauts Yuri Gagarin and Vladimir Komarov, and Apollo 1 astronauts Gus Grissom, Ed White and Roger Chaffee. The time spent on EVA during Apollo 11 was about two-and-a-half hours.

Return To Earth:

After they re-entered the LM, the hatch was closed and sealed. While preparing for the liftoff from the lunar surface, Armstrong and Aldrin discovered that in their bulky spacesuits, they had broken the ignition switch for the ascent engine. Using part of a pen, they pushed the circuit breaker in to activate the launch sequence. The three astronauts returned to Earth and splashed down in the Pacific Ocean.

After being released from an 18-day quarantine to ensure that they had not picked up any infections or diseases from the Moon, the crew were feted across the United States and around the world as part of a 45-day “Giant Leap” tour.

and Volatile EvolutioN is a space probe that is designed to orbit Mars .The mission will aim at studying the atmosphere of Mars .The mission   proposed by NASA’s Mars Scout Program is the only selested Mars mission by NASA in the present and expected to be launch in late 2013 .The most important and the basic  parts of the mission , building as well as testing will be done by Lockheed Martin Space System having its headquarter at Colorado and deals in manufacturing of satellites , missile defense and various other instruments and have already helped NASA in various past missions too. Along with that, launching will also take place under their supervision. The principal investigator of the mission is Bruce Jakosky who is presently working at University of Colorado. Other than this, the university will also be helping in the co-ordination activities of the mission including the help in manufacture of instruments of the mission. The safety is the first step for each and every mission and that must be ensured for a mission like MAVEN as it will be a milestone in the history of Mars mission, having a huge investment. NASA Goddard will be assuring safety for this mission; it will be designing the mission system and will also provide the instruments. NASA managed to take as many responsibilities as possible and thus the activities after mission launching, including navigation support deep space network and Electra telecommunication will be operated by NASA’s Jet propulsion laboratory in California.
