well, potatoes can be used to produce ethanol... renewable fuel for power generation on long space flight.

so...

5 UK Sattelites, that's going to cause a lot of butt hurt in UK.

Who will put Indian scientists in jail and shut Space Agency when Indian farmers are suiciding.

ISRO launches will provide huge revenues for the Government and Government of India will investment the money for the upliftment of not only farmers but even for the upliftment of economically backward Indians.

The Polar Satellite Launch Vehicle (PSLV), in its thirtieth flight (PSLV-C28), will launch three identical DMC3 optical earth observation satellites built by Surrey Satellite Technology Limited (SSTL), United Kingdom (UK). The three DMC3 satellites, each weighing 447 kg, will be launched into a 647 km Sun-Synchronous Orbit (SSO) using the high-end version of PSLV (PSLV-XL) from Satish Dhawan Space Centre, Sriharikota (SDSC-SHAR), the spaceport of India. PSLV-C28 will be the ninth flight of PSLV in ‘XL’ configuration.

The PSLV-C28, in addition to the three DMC3 satellites, will also carry two auxiliary satellites from UK, viz., CBNT-1, a technology demonstrator earth observation micro satellite built by SSTL, and De-OrbitSail, a technology demonstrator nano satellite built by Surrey Space Center.

With the overall lift-off mass of the five satellites amounting to about 1440 kg, this mission becomes the heaviest commercial mission ever undertaken by Antrix/ISRO.

Accommodating the three DMC3 satellites each with a height of about 3 metre within the existing payload fairing of PSLV, was a challenge. To mount these satellites onto the launcher, a circular Launcher adaptor called as L-adaptor and a triangular deck called Multiple Satellite Adapter-Version 2 (MSA-V2), were newly designed and realized by ISRO for this specific purpose.
These international customer satellites are being launched as part of the arrangement entered into between DMC International Imaging (DMCii), a wholly owned subsidiary of SSTL, UK; and Antrix Corporation Limited (Antrix), the commercial arm of Indian Space Research Organisation (ISRO), a Government of India Company under Department of Space.

The DMC3 constellation, comprising of three advanced mini-satellites DMC3-1, DMC3-2 and DMC3-3, is designed to address the need for simultaneous high spatial resolution and high temporal resolution optical Earth Observation. Launched into a single Low-Earth Orbit plane and phased with a separation of 120° between them, these satellites can image any target on the Earth’s surface every day. Major application areas include surveying the resources on earth and its environment, managing urban infrastructure and monitoring of disasters.

CBNT-1, weighing 91 kg, is an optical Earth Observation technology demonstration micro satellite built by SSTL. The 7 kg De-orbitSail from Surrey Space Centre, is an experimental nano satellite for demonstration of large thin membrane sail and drag deorbiting using this sail.

Daily maul will go berserk

 

[Ajit Kumar]

why not ?? a "vertical farm" design and construction for potato growing is so much more useful than isro putting up yet another satellite.



how ??



well, potatoes can be used to produce ethanol... renewable fuel for power generation on long space flight.

so...

m which can grow communist oil ?

m which can grow communist oil ?

are you referring to "vertical farms", or something else ??

I can't wait to see the Daily Fail article...

seems suicides are a source of mirth for you.

Indian Space Research Organisation set to launch five British satellites - The Hindu
Updated: July 8, 2015 13:53 IST
According to ISRO, this is the heaviest commercial luggage carried by a PSLV rocket to date.
The Indian space agency on Wednesday morning began the countdown for the July 10 rocket launch that would carry five British satellites.

According to Indian Space Research Organisation (ISRO), the 62 hours and 30 minutes countdown for the July 10th night launch of rocket Polar Satellite Launch Vehicle (PSLV) XL variant began at 7.28 a.m. on Wednesday.

The rocket is scheduled to blast off at 9.58 p.m. on July 10 from the first launch pad with five satellites together weighing around 1,440 kg, for an undisclosed fee.

Since 1999, India to date has launched 40 satellites of other countries and the successful launch of the five British satellites would take the tally to 45.

The 44.4 metre tall and 320 tonne PSLV is a four stage/engine rocket with six strap-on motors for addition thrust during the initial phase of the flight.

The first and third stages are powered by solid fuel and are cast ready while the second and fourth stages are powered by liquid fuel which will be filled during the countdown.

Apart from fuelling up the engines, all the systems would be checked and rechecked during the countdown.

According to ISRO, this is the heaviest commercial luggage carried by a PSLV rocket to date.

Of the five British satellites, three are identical DMC3 optical earth observation satellites weighing 447 kg. These will be put into a 647km sun-synchronous orbit.

Of the other two satellites, CBNT-1 weighs 91 kg and also is an optical earth observation technology demonstration microsatellite, while the remaining De-OrbitSail weighs 7 kg. This is an experimental nano-satellite for demonstration of large thin membrane sail-and-drag deorbiting.

The total duration of the launch — from the rocket’s blast off to the fifth satellite separation — will be around 19 minutes 16 seconds.

The three DMC3 and the CBNT-1 satellites were built by Surrey Satellite Technology Ltd. The De-OrbitSail was built by Surrey Space Centre.

According to ISRO, accommodating the three DMC3 satellites (each with a height of about three metres within the existing payload fairing or the heat shield of the PSLV) was a challenge. Thus, a circular L-adaptor and a triangular Multiple Satellite Adapter-Version 2 (MSA-V2) were newly designed and realised by ISRO for this specific purpose.

France’s SPOT 7 satellite weighing 714 kg was the heaviest single foreign satellite carried by a PSLV rocket untill now. It was launched on June 30, 2014.
