India from space
This week most of the on line editions of national news papers
covered a report about India's satellite images,
which were thankfully received from:
nasa.gov
ISS
Chandrayaan-1
Mangalyaan
ISRO
******
These images are very interesting as they show:
Indo-Pak border that is lit by floodlights.
The
floodlights dot the border in Gujarat to prevent smuggling and arms
trafficking.
(certain borders are fortified more than others. The US-Mexican border,
the India-Pakistan border, the separation wall between Israel and the
Palestinian territories, and the demilitarized zone between North and
South Korea are among the places where the toughest national security
and anti-movement policies are in force.
The border between these two countries is hotly contested, especially in
the region of Kashmir. India is also wary of terrorist infiltration
along the entire border. Sometimes called the “Berlin Wall of Asia”, the
border has only one road crossing. Half of the border is floodlit, and hence can be seen from space.)
NASA has also captured some amazing photos
of the
Sundarbans area and the Ganges valley in Brahmputra.
These unseen
photos of India from space show cities
like Mumbai and Delhi, forest
fires, and lakes.
There are also images of India taken from Indian
satellites Chandrayaan and Mangalyaan here.

Photograph taken from International
Space Station, you can clearly see border between India and Pakistan
due to special security lighting in orange. The Indian government
sanctioned a move to erect floodlights along the terrain separating
India and Pakistan in the Gujarat sector in 2003 to prevent smuggling
and arms trafficking. Courtesy: ISS

his image of New Delhi was captured
by the Advanced Spaceborne Thermal Emission and Reflection Radiometer
(ASTER) on NASA’s Terra satellite on September 22, 2003. The dramatic
differences in the landscapes tell some of the city’s history. Little
vegetation interrupted the urban expanse. In contrast, the buildings of
New Delhi were laid out along wide, tree-lined avenues that connected
monuments, parks, and government buildings. Among the most obvious of
these avenues is the Rajpath, visible as a green strip across the heart
of New Delhi. The Rajpath connects the grounds of the President’s estate
on the west to the India Gate (a World War I memorial) on the east. To
the west of New Delhi is the Central Ridge Forest Reserve, which gives a
hint of how the landscape would have looked before human development.

In this true-color MODIS image from
October 23, 2001, the semi-arid Tibetan Plateau (upper left) meets up
with the Himalayas to the south. From the heights of the Himalayas,
snow-covered on their northern flanks, and lush with vegetation to the
south, numerous rivers, brown with churned up sediment, flow into the
valley of the Brahmaputra River in Assam, India. Courtesy: nasa.gov

India’s Hugli River (sometimes
spelled “Hooghly”) is a Ganges River distributary, one of the many
branches of the river that are collectively known as the “Mouths of the
Ganges.” As the Ganges approaches the coastal plain, the river fans out
over the flat terrain of Bangladesh and West Bengal, India, as numerous
meandering channels. The Hugli branches off the Ganges about 200
kilometers north of Calcutta, and the river flows past the city before
emptying into the Bay of Bengal. Courtesy: nasa.gov

A large fire was burning in India’s
Sri Venkateshwara National Park on March 24, 2014, when the Moderate
Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite
acquired this image. The fires are outlined in red. The park consists of
dry deciduous forest, and is home to a wide range of rare wildlife,
including tigers and the golden gecko. According to local news reports,
several forest fires have burned in national parks and wildlife reserves
in the hills of Andhra Pradesh over the past week. The protected
forested land is dark green in contrast to the surrounding tan
landscape. Courtesy: nasa.gov

This image, taken by astronauts
aboard the International Space Station, shows Lake Sambhar’s eastern
saltworks in detail. Today, they are operated by a joint venture between
Hindustan Salts and the Government of Rajasthan. East of the dam is a
railroad, built by the British (before India’s independence) that
provides access from Sambhar Lake City to the salt works. Courtesy:

NASA's Aqua satellite captured an
image of Tropical Cyclone Lehar after it weakened to a depression and
neared the coast of India on November 29. Lehar made landfall south of
Machillipatnam. Courtesy: nasa.gov

The Advanced Spaceborne Thermal
Emission and Reflection Radiometer (ASTER) flying on NASA’s Terra
satellite acquired this image of Lonar Crater on November 29, 2004. In
this simulated-true-color image, pink-beige indicates bare ground, blue
and off-white indicate human-made structures, dark blue indicates water,
green indicates vegetation, and dull purple indicates fallow fields. A
vegetation-lined lake fills the crater, one of the few natural features
of this scene. Signs of human habitation surround the lake, especially
the cluster of blue and off-white points to its immediate northeast.
Outside of this settlement, the vicinity is a patchwork of agricultural
fields. Courtesy: nasa.gov

This image mosaic is comprised of
three astronaut photographs acquired within ten seconds of each other as
the International Space Station passed over India. Almost cloud-free
conditions reveal the continuous urban land cover of the megacity
extending north to south across Salsette Island—a distance of nearly 50
kilometers. Sanjay Gandhi National Park, bordered on three sides by the
urbanized area, is the largest national park in the world located within
city limits. In addition to providing a refuge for native plants and
animals (including humans), the park also includes two lakes that form
part of the Mumbai drinking water system. Courtesy: nasa.gov

With its 14 spectral bands from the
visible to the thermal infrared wavelength region and its high spatial
resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth
to map and monitor the changing surface of our planet. ASTER is one of
five Earth-observing instruments launched Dec. 18, 1999, on Terra. The
instrument was built by Japan's Ministry of Economy, Trade and Industry.
A joint U.S./Japan science team is responsible for validation and
calibration of the instrument and data products. Courtesy: nasa.gov

North of the Bay of Bengal in
eastern India, the city of Calcutta (large purple area) hugs the eastern
bank of one of the myriad channels that split off the Ganges River
before it empties into the Bay. The arm of the Ganges that runs through
Calcutta is known as the Hooghly River. It is the large, pale green
river running through the left side of the image. Calcutta, also
referred to as Kolkata, is about 100 miles north of where the Hooghly
empties into the Bay via the Mouths of the Ganges. Courtesy: nasa.gov
