ISRO General News and Updates

[Aaj ka hero]

My reply was to the claim of Cartosat-3 being the most powerful optical reconnaissance satellites which it is not. WTF are you on about?

I am just saying
YOU WILL SEE MORE of SUCH GOOD SATELLITES FROM INDIANS if USA rescind little bit on IRAN OIL IMPORT.
More dollars are available for us then, you know.

India has to label this a civilian earth observation satellite and keep it at 25cm.
US/NATO have 10cm satellites for military purpose only; I don't think Japan,israel or china
have 10cm??? I don't know if there is a significant difference from 10cm to 25cm from 500km
above the earth???? But as far as civilian labelled satellites go we have reached the limit
created and dictated by other countries/organizations. We indirectly may have access to 10cm
resolution if needed thru intelligence gathering agreements.(will not name with who)

We do have . Post balakot some ally of ours had validated strikes......

actually it does--at same distance US 224 which took that photo has resolution of 8 cm or less & that was a decade ago--the way ASAT weapons are proliferating, further the satellite more difficult it is to track + more time for counter measure & evasive manoeuvre. US & Russky optical satellite don't even have to pass over the target country to get good resolution images keeping themselves safe. But cartosat are fine nonetheless.

Do our satellites have counter measures to disappear?
Here is a old video of Lacrosse satellite disappearing.

 

[Indx TechStyle]

I thought we made the best remote sensing satellites.

We don't. We have started to crack "One of the best list recently".

no it can't.....................

It can. Orientation & obstacles due to horizon have their own limits however.

It can. Orientation & obstacles due to horizon have their own limits however.

25 cm resolution can't cheat your notebook from space not even 10 cm sat can do that...best it can do is tell there is a number plate on a car. I doubt it can even do that.

 

[LETHALFORCE]

Some info does not need to be made public. Members use your judgement

if they have we won't even know but US & Russky have it in their most advance reconnaissance satellite. Look at so called Zuma launch failure.
US have inflatable structures to hide satellite's patented back in 90s

A falling rocket booster just completely flattened a building in China

Despite how easy it is to prevent, China continues to allow launch debris to rain down on rural towns and threaten people’s safety.

Last Saturday, China launched a pair of satellites into orbit from its Xichang Satellite Launch Center. On social media, however, the main event was what happened on Earth: a booster from the launch smashed right into a building in the country’s rural south-central region. No one was injured, but videos and photos of the incident showed wreckage left in the booster’s wake, with toxic rocket fuel evaporating.

This is the aftermath downrange following a Chinese Long March 3B launch from Xichang early Saturday. And that yellow smoke is very toxic hypergolic propellant. Source: https://t.co/VEh5X8Ors0pic.twitter.com/22IVIpyJOk

It’s the latest incident in China’s long history with falling rocket parts causing destruction below. The most infamous crash occurred in 1996, when the first Long March 3B launch saw the rocket veer off course and crash into a village, killing an unknown number of people (possibly hundreds, by some Western estimates).

“Any time you have stuff going up, there’s a possibility it’s going to come down where you don’t plan for it,” says Victoria Samson at the Secure World Foundation. “So there’s a reason why you don’t fire over populated land.” That’s why most countries launch over water.

So why doesn’t China? “This entire issue is down to geography,” says Thomas Roberts, a former aerospace security fellow at the Center for Strategic and International Studies. All three of China’s main spaceports are located in the mainland, including the Xichang site. They all save money by flying missions east (which requires less fuel to get into space), but that route takes them over vulnerable populations.

severe organ failure or cancer), the wreckage could pollute nearby rivers and streams used for irrigation and drinking water. Launches from the Soviet Union’s old Baikonur Cosmodrome in Kazakhstan, built in 1955, have caused more than 2,500 tons of debris to rain down on the surrounding region, leading to health problems for thousands.

So the issue isn’t new, but the space industry is expanding rapidly. “The more launches you have, the more chances you have for something to go wrong,” says Samson.

Luckily, the solutions aren’t complicated—they just require political will. China can launch over the water if it wants, through its spaceport on the island of Hainan in the South China Sea. Operational since 2014, it’s been seldom used because of launch failures and a less developed infrastructure. But these issues are fixable with enough investment.

China could also just change its flight paths. For example, Israel’s Palmachim Airbase can’t launch to the east because of obvious geopolitical conflicts. So it sends rockets over the Mediterranean Sea and through the Strait of Gibraltar. This requires putting a satellite in a retrograde orbit—one that moves in the opposite direction of Earth’s rotation. This requires much more fuel, but it entirely avoids populated areas.

And some emerging technologies might enable rockets to fly over populated areas more safely. Grid fins (lattice structures that can slightly modify control and speed) and parafoil features (aluminum foils that work like kites or parachutes), like those SpaceX uses, could help steer falling rocket boosters to vacant lands. Roberts thinks AI could one day be used to better assess downrange risks to communities before launch. One proposal led by SpaceX calls for building a flight corridor heading south that would fly rockets over populated areas as long as they can demonstrate a perfectly functional automated abort feature.

There’s one very cheap tool that could increase pressure on China and other groups to take steps to mitigate launch debris hazards: social media. Weibo and Twitter helped make images and videos of the latest crash go viral––a massive boon to the poor, rural victims, who are rarely seen or heard.

Land acquisition underway for 2nd rocket port in Tuticorin

Land acquisition underway for 2nd rocket port in Tuticorin

Chennai, Nov 29 (IANS) The land acquisition in Tamil Nadu''s Tuticorin district for India''s second rocket port is under progress, a top district official said on Friday.

"The process for acquiring land for the rocket launching pad has begun. The land requirement will be about 2,300 acres. The project activity is expected to begin in six months time," Tuticorin District Collector Sandeep Nanduri told IANS.

"The government has a proposal to set up a rocket launching pad near Kulasekarapattinam in the state of Tamil Nadu," Union Minister of State for Atomic Energy and Space, Jitendra Singh told the Rajya Sabha on Thursday.

With the Indian Space Research Organisation (ISRO) increasing its rocket launch missions, a need has been felt for a second rocket port.

The Indian space agency is also in the process of realising a small rocket with a carrying capacity of 500 kg. ISRO currently flies two kinds of rockets - the Polar Satellite Launch Vehicle (PSLV) and the Geosynchronous Satellite Launch Vehicle (GSLV).

Major space faring nations have multiple rocket launch sites.

India presently has one rocket port at Sriharikota in Andhra Pradesh with two launch pads.

"Tuticorin is a good location for a rocket that needs to fly southwards. As a matter of fact, it was considered long ago for locating a rocket launching site but the locals opposed this," an ISRO official had earlier told IANS.

"A rocket launch site should be on the east coast and near the equator. And Tuticorin district satisfies that condition," a former ISRO official had told IANS.

A spaceport in Tuticorin district would thus be ideal for putting satellites in polar orbit normally undertaken through a PSLV rocket, and not for satellites with geostationary orbits launched by GSLV rockets.

Besides, ISRO has its Liquid Propulsion Systems Centre (LPSC) at Mahendragiri in Tirunelveli district where it assembles the second and fourth stage engines for the PSLV.

Instead of transporting the second and fourth stages to Sriharikota from Mahendragiri it would be easier to shift them to the launch pad if it is built in Kulasekarapattinam which is around 100 km away.

India must build satellite to harness solar energy from space, former DRDO chief Sivathanu Pillai says | Chennai News - Times of India

CHENNAI: India should work with friendly nations to build a solar power satellite and place it in orbit to harness solar power as the country is running out of conventional sources like coal, says former chief of DRDO A Sivathanu Pillai.
“One nation cannot do this. So, India should work with friendly nations, which have equal interest, to develop a technology to harness the solar energy from space for sustainable growth,” Pillai told TOI on the sideline of the TAN-ENERGY Summit 2019 here on Friday. The summit was organised by the Federation of Indian Chambers of Commerce and Industry (FICCI).
He said the heat energy should be harnessed and converted into microwaves. It should be channalised to the earth. “A floating station on the sea is the best option to receive it and convert it into electricity. The same can be used to operate desalination plants,” he said.
Technology should be developed, keeping in mind the living organism and birds in the earth, to safely transport the energy from the orbit to the earth, he added.

I had read about this a few years ago. I think Japanese are doing research in this field. Its called space based solar power.
Great concept but dont know how feasible it is.
