The world’s first commercial fully re-programmable satellite lifted off from French Guiana on Friday on board an Ariane 5 rocket, ushering in a new era of more flexible communications.

Unlike conventional models that are designed and “hard-wired” on Earth and cannot be repurposed once in orbit, the Eutelsat Quantum allows users to tailor the communications to their needs—almost in .

The satellite will be placed in orbit some 36 minutes after the launch.

Because it can be reprogrammed while orbiting in a fixed position 35,000 kilometers (22,000 miles) above the Earth, the Quantum can respond to changing demands for and secure communications during its 15-year lifetime, according to the European Space Agency.

The 3.5 ton Quantum model has eight communications beams, each of which can be modified to change its area of coverage and also the power of the telecommunications signal it emits.

Using software made available to the customer, these changes can be made “in a matter of minutes”, according to Eutelsat.

This means the satellite can be used to provide mobile coverage for moving objects such as aircraft or oceangoing vessels, or to provide coverage after a natural disaster or for one-off events.

And at a time of growing concern over digital security—as well as the possible weaponising of space—Quantum is able to pinpoint the origin of signals emitted with or without malicious intent and take action to remedy the interference.

The Quantum will cover a large geographical area from West Africa to Asia for 15 years.

Hexbyte Glen Cove World’s smallest hog released into wild in India by conservationists

A dozen of the world’s smallest pigs have been released into the wild in northeastern India as part of a conservation programme to boost their population.

A dozen of the world’s smallest pigs have been released into the wild in northeastern India as part of a conservation programme to boost the population of a species once thought to have become extinct.

The pygmy hog, which has the scientific name porcula salvania, lives in tall, wet grasslands and was once found along plains on the Himalayan foothills in India, Nepal and Bhutan.

Its declined in the 1960s, leading to fears it had become extinct until it was rediscovered in India’s northeastern state of Assam in 1971, conservationists say.

By 1993, it was only found in a few pockets of Assam’s Manas National Park, which borders Bhutan.

The Pygmy Hog Conservation Programme, involving several organisations including from state and national governments, established a captive breeding scheme with six hogs in 1996 to try and revive their population.

“This time we are releasing 12 pygmy hogs including seven male and five female,” the programme’s field scientist Dhritiman Das told AFP at the release site in Manas National Park on Saturday.

Eight of the hogs were released in Manas on Tuesday and four more on Saturday. Some 14 were released last year.

The programme looks after around 70 captive hogs and is breeding more to be released.

The pygmy hog, which has the scientific name porcula salvania, lives in tall, wet grasslands.

The past week’s releases take the number of pigs reintroduced into the wild by the programme to 142.

The wild population is estimated to be less than 250, conservationists say.

“In next four years, we target to release 60 hogs… so that they can build their own population in the wild,” Das added.

The programme has also sought to rehabilitate the grasslands home to the tiny creatures, which measure about 25 centimetres (9.8 inches) in height and 65 centimetres in length and weigh around 8-9 kilogrammes (17.6-19.8 pounds).

The species’ survival has been threatened by the loss and degradation of its habitats due to such as settlement and agriculture, and the improper management of such areas, experts say.
