)Yes! The idea of "disk/record" was added *much* later in the project. So things had to move incredibly fast and budget was very low. As said, whole greetings business was done by international students (or their families).. Prof Khare was responsible to get the indian community to cover all the Indian languages used there. (regretfully not all the languages were covered but consulate/UN etc would not help). The child's voice in Neshant's clip above is Carl Sagan's son. The cover design - line drawing of human couple was done by Sagan's wife.... most of the technical help was provided by Cornell (and not professional actors/Nasa etc)... The indian music (a Krisna bhajan by Kesar Bai) is copied from a record which was purchased from a grocery store in NYC.Katare wrote:Amber, great experience.

1. Cryogenic Upper Stage (CUS) for GSLV MkIII on February 17, 2017, for a flight duration of 640 seconds
2. C25 Stage had earlier been tested successfully for 50 seconds on January 25, 2017 to validate all the systems.
3. This one was for 200 secs, somewhere in the middle
4. Wiki baby search had the following info
Stage 1 Burn time: 100 s
Stage 2 Burn time: 139s
So effectively it would be full stage 1 & 85% of stage 2

NEW DELHI: After a lull of five months, Indian Space Research Organisation (Isro) is gearing up for a flurry of space activities from September as it will conduct 19 launches, including the Chandrayaan-2 mission, in just seven months.
Isro chairman K Sivan told TOI, “We are going to conduct 19 missions, including 10 satellites and nine launch vehicles, between September and March. For Isro, this will be the highest density period for launches as never before we had launched two satellites within 30 days consecutively for months.
We will resume our services on September 15 with the PSLV C42 mission, which will totally be a commercial launch.” PSLV C42 will carry UK satellites — Novasar and S1-4 — as the main payload.
In October, Isro will launch GSLV MkIII-D2, also known as ‘bahubali’. This will be the second launch of Isro’s most powerful rocket with 4-tonne lifting capability. The rocket will lift off with GSAT-29 satellite with multi-beam and optical communication payloads, which will help bridge the digital divide in rural regions.
In October itself, another launch of PSLV C43 is scheduled that will carry HySIS or hyperspectral imaging satellite. The satellite is set to add teeth to the way India is gleaned from 630 km altitude as it will enable the country to see in 55 spectral or colour bands.
In November too, Isro will launch two satellites. GSLV F11 will launch GSAT-7A, a satellite dedicated for the IAF, which will help the force interlink their bases, ground radar stations and AWACS aircraft. Thereafter, Isro will launch 5.6 tonne GSAT-11, its heaviest satellite ever made, from French Guiana on November 30. The satellite came into limelight when it was recalled in April from Arianespace to look for any possible anomaly. In December, Isro’s PSLV C44 will launch Emisat. The same month Isro will launch GSAT-31 from French Guiana. This communication satellite will be a replacement for Insat 4CR.
Isro will usher in next year with the launch of its highly ambitious Chandrayaan-2 mission. The launch window will be from January 3 to February 16. Israel, too, is launching its moon mission around the same time. It will be a neck-and-neck race between the two to become the fourth country in the world after Russia, US and China to do a soft-landing on the lunar surface. In January itself, Isro’s PSLV C45 rocket will carry a remote sensing satellite Risat-2B.
In February, PSLV C46 will launch two satellites — Cartosat-3, a remote sensing satellite, and NEMO AM, the next-generation earth monitoring and observation-aerosol monitoring satellite. In March, Isro plans to launch another reconnaissance satellite Risat-2BR1. Risat-2B, Cartosat-3 and Risat-2BR1 will increase the surveillance capabilities of the country.
BENGALURU: Two years after China opened a ground station at the North Pole, the Indian Space Research Organisation (Isro) plans to set up its first overseas ground station there, primarily to augment the Indian Remote Sensing (IRS) operations crucial not just for civilian needs like disaster management but also for the armed forces.
Isro has a full-fledged IRS programme with a constellation of earth observation satellites, with the National Remote Sensing Centre (NRSC), Hyderabad managing data acquisition and processing, data dissemination, aerial remote sensing and decision support for disaster management.
“The plan will take some time to materialise as it involves huge logistical challenges, international approvals and co-operation,” a scientist said, adding that any hardware installation is a complex task and challenges are tougher given the extreme weather conditions.
Another scientist explained that with advancements in high-resolution satellite programmes, the complexity and role of ground stations have increased multifold. “This ground station will provide an opportunity to download complete data within the same orbit and enable use of onboard resources in every orbit,” he added.
The agency, which was supposed to establish a second data reception antenna at Antarctica Ground Station for Earth Observation Satellites (AGEOS) this year, will now do it next year. “The proposal was to set up a second data reception antenna system to support reception from two specific projects immediately and future ones later,” scientists said.
Can it be for China? I think any point in China will be closer to India than North Pole.SaiK wrote:well.. surely it can be dual use - especially, if we need to track mid-course flight.
50 to 60 SSLV is required. We don't want to spend our energies on this. Via Antrix we want industry to come in a big way.
Small satellite business is growing. 1100 satellites predicted in LEO. To catch up with the small sat market we need industry support in a big way. SSLV integration will happen on 72 hours.
Gaganyaan - industry will play a key role. It is a challenge for us since the payload will be humans. We will focus next 4 years on HSP. Industry must come together and help us.
France offers space medicine and other critical life support for @isro #Gaganyaan mission. A MoU in this regard likely to be inked during @SpaceExpoIndia
Instead of identifying a thing by shape, that requires optical resolution to gather enough pixels AND good contrast against background (at limits of optical resolution due to optics and or dynamic abbration, say due to atmospheric thermals), hyperspectral allows a single pixle (with hyper spectral sensing) to identify the spectrem is result of a pre known object of qty x, and one or more other pre known object withe respective qty, where thousands of pre known components with respective spectral signature are tagged.kit wrote:What exactly does the hyperspectral satellite do ??

For example a SU30 with IRST has fixed small optical aperture, that limits it's detection range to detect and classify a faroff aircraft even in clear weather due optical resolution maxing out. OR detecting ground targets that are camouflaged. Hyperspectral techniques allows determining on one pixle what collection iteams it is and how many.

NEW DELHI: Reliance Jio is planning to use satellites to connect to the rural and remote parts of India through its 4G LTE-based voice and data service. It is deploying a first-of-its kind satellite backhaul-based network, using capacity from Indian Space Research Organisation (ISRO), and technology from Hughes Communications (HCIL).
The Mukesh Ambani-led 4G telco is connecting more than 400 LTE sites which are beyond the reach of terrestrial backhaul services through this satellite backhaul-based network. The network is under different phases of deployment.
Jio has awarded a contract worth over $10 million to Hughes Communications (HCIL) to set up the satellite backhaul for the 4G network in these areas.
In India, most telcos, including Jio, use microwave largely to connect towers since laying fibre is tough due to high deployment costs and right of way (RoW) issues. In rural and remote parts, especially hilly areas and islands, using the microwave is even more challenging due to height, a difficult terrain and the huge investments involved, which is where the satellite-based network can fit in.
Jio group president Jyotindra Thacker said the telco is using Hughes’ Jupiter system to support its 4G sites. “The satellite system is key to enabling our vision of providing ubiquitous and seamless connectivity to each and every part of the country.”
Partho Banerjee, president, Hughes Communications India, said that satellite is the ideal technology for extending 4G/LTE service to remote and rural communities.
Telcos such as Bharat Sanchar Nigam Ltd., Vodafone Idea, and Bharti Airtel have been doing satellite backhauling to a small extent, albeit for 2G and 3G services, industry watchers said, adding that BSNL has the most satellite backhauling today for 2G and 3G.
“On 4G though, Jio is the innovator by far on satellite backhauling…they have taken a bulk capacity of two satellites of ISRO, and have taken our satellite technology which is meant for 4G services. Jio wanted a captive network of their own, and is the first in the industry to do this,” Shivaji Chatterjee, SVP & Head - Enterprise Business, Hughes Communications India, told ET.
Jio, in partnership with Hughes, is setting up two earth stations in Mumbai and Nagpur, and will set up two mini hubs in Leh and Port Blair for the latest satellite backhaul-based services that will provide connectivity in areas, especially in the North East, Jammu and Kashmir Uttaranchal, Andaman Nicobar, and Lakshadweep.
“The focus may be on remote and hilly and island areas, but also on remote areas in the mainland in Maharashtra, Orissa, Chhattisgarh, Karnataka, Himachal Pradesh,” Chatterjee explained.
Analysts said that satellite can't match microwave or fibre, but still provides more than enough capacity to offer bandwidth wherein each site can provide speeds between 10 Mbps and 30 Mbps.
Chatterjee said that the satellite platform being used by Jio offers certain kind of compression and acceleration natively for LTE traffic, providing 50% advantage in terms of bandwidth.
You do know that these expos are very popular and trigger enthusiasm in children. My Son did his aerospace engineering and was motivated by the outreach programs and competitions that ISRO conducts yearly . NASA has attracted bright talent buy doing these and whats wrong in ISRO trying to do this. Incidentally this expo has drubbed a lot of business too for Antrix.rsingh wrote:

More in the link below.The deputy director of Indian Space Research Organization’s (ISRO) Space Application Centre (SAC) has said that
mobile phones in India could carry NavIC, a homegrown variant of the Global Positioning System (GPS), by early next
year. The comments came during a panel discussion at the Bengaluru Space Expo, 2018 which is underway in the
Karnataka capital.
...
While the roll-out of NavIC is expected early next year, it would not be mandatory for everyone to carry the system
as there is no law in force which would mandate the same. It has been noted that Russia has a regime in force whereby
mobiles in the country have to carry Glonass which is the Russian positional system.
Don't do this.Read again. US,Russia did this for themselves. we have to do this for ourselves. But that is not the point. Point is ; make it, test it and use it and then display it. That is an achievement. Yes kids get inspired . I still have somewhere cuttings of Rohini etc. I am (and many others are) sick and tired of perpetual postponement of big projects. Get on the work and deliver within time frame instead of wasting time in discussing every nut and bolt with public before the big show.arshyam wrote:Then why even do this?

So if I understand right, ISRO is all one guy building the rockets, satellites while also doing the marketing, brochures, exhibitions and so on. Makes absolute sense that guy needs to focus on the rockets. No wonder we have a few failures from the past few years.rsingh wrote: Don't do this.Read again.
