Indian Space Research Organisation and location and navigation technology solutions provider MapmyIndia announced an initiative to partner together to offer India’s best, and fully indigenous, mapping portal, and geospatial services.
It combines the power of MapmyIndia’s digital maps and technologies with ISRO’s catalogue of satellite imagery and earth observation data, according to MapmyIndia’s CEO and Excutive Director, Rohan Verma.
He termed it a path-breaking milestone in India’s journey towards Aatmanirbhar Bharat, wherein Indian users would not be dependent on foreign organisations for maps, navigation, and geospatial services, and leverage made-in-India solutions instead.
“You don’t need Google Maps/Earth any longer”, Verma said in the headline in an article on LinkedIn.
According to ISRO, the Department of Space (DoS) – ISRO comes under it – has joined hands with MapmyIndia to combine their geospatial expertise and build holistic solutions by leveraging their geoportals.
DoS entered into an MoU with geospatial technology company CE Info Systems, which owns MapmyIndia, on Thursday.
Under the partnership, the combined geospatial expertise of the DoS and CE Info Systems would be leveraged through their respective Geoportals, according to Bengaluru-headquartered ISRO.
The collaboration will enable them to jointly identify and build holistic geospatial solutions utilising the earth observation datasets, NavIC, Web Services, and APIs (application programming interface) available in MapmyIndia, Bhuvan, VEDAS, and MOSDAC geoportals, the space agency said in a statement.
Indian Regional Navigation Satellite System (IRNSS) called NavIC (Navigation with Indian Constellation, is India’s own navigation system, developed by ISRO. Bhuvan is the national geo-portal developed and hosted by ISRO comprising geospatial data, services and tools for analysis.
VEDAS (Visualisation of Earth observation Data and Archival System) is an online geoprocessing platform using optical, microwave, thermal, and hyperspectral EO data covering applications particularly meant for academia, research and problem solving, according to ISRO.
MOSDAC (Meteorological and Oceanographic Satellite Data Archival Centre) is a data repository for all the meteorological missions of ISRO and deals with weather related information, oceanography and tropical water cycles.
Verma said there are many reasons why Indians are better off with an indigenous solution for maps and geospatial services.
“MapmyIndia, being a responsible, local, Indian company, ensures that its maps reflect the true sovereignty of the country, depicting Indias borders as per Government of India, and hosts its maps in India,” he said.
Through the combined partnership with ISRO, MapmyIndias end user maps, apps and services will now integrate with ISROs huge catalogue of satellite imagery and earth observation data, a MapmyIndia statement said.
It would be a much better, more detailed and comprehensive, as well as privacy-centric, hyper local and indigenous mapping solution for Indians, compared to foreign map apps and solutions, it said.
Verma said foreign mapping solutions come with a lot of hidden costs.
“For example, foreign search engines and companies claim to offer free maps, but in reality they make money by targeting the same users with advertising based on invading user privacy and auctioning those users private location and movement data,” he claimed.
“This should be very alarming to all citizens”.
“On the other hand, MapmyIndia has an ethical point of view against advertising led business models of such companies, and hence, does not have an advertising business model. By using MapmyIndia maps and applications instead of the foreign map apps, users can better protect their privacy,” he said.
The “sustainable and direct, clean business model” ensures that MapmyIndias maps and apps can be kept free of cost as well as free of ads for users, according to him.
“MapmyIndias maps cover all 7.5 lakh villages, 7500+ cities at street and building-level, connected by all 63 lakh kilometres of road network pan India and within cities, in total providing maps for an unparalleled 3+ crore places across India,” the company statement said.
ISRO’s Faces SSLV-D1 Data Loss at Terminal Phase of the Mission, Placed in Wrong Orbit
By ANI | Updated: 8 August 2022
The Indian Space Research Organisation (ISRO) on Sunday said its Small Satellite Launch Vehicle (SSLV-D1) placed satellites into elliptical orbit instead of a circular orbit. Sharing the updates of its satellite launch, ISRO said “SSLV-D1 placed the satellites into 356kx76km elliptical orbit instead of 356km circular orbit. Satellites are no longer usable. The issue is reasonably identified. Failure of a logic to identify a sensor failure and go for a salvage action caused the deviation. A committee would analyse and recommend. With the implementation of the recommendations, ISRO will come back soon with SSLV-D2.”
Earlier in the day, ISRO launched its first new rocket the Small Satellite Launch Vehicle (SSLV-D1) carrying Earth Observation Satellite (EOS-02) and a student-made satellite-AzaadiSAT from the Satish Dhawan Space Centre (SDSC) in Andhra Pradesh’s Sriharikota.
To mark the country’s celebrations of “Azaadi Ka Amrit Mahotsav”, the SSLV, co-passenger satellite called “AzaadiSAT” comprising 75 payloads built by 750 students from 75 rural government schools across India was launched.
ISRO Chairman S Somanath on Sunday said that both Small Satellite Launch Vehicle (SSLV-D1) carrying Earth Observation Satellite (EOS-02) were injected but the “orbit achieved was less than expected which makes it unstable.”
“All stages performed normal. Both satellites were injected. But the orbit achieved was less than expected which makes it unstable,” the ISRO chief said.
He further said that the SSLV-D1 suffered data loss at the terminal phase of the mission.
“In the terminal phase of the mission, some data loss is occurring. We are analysing the data to conclude the final outcome of the mission with respect to achieving a stable orbit,” Somanath added.
Girls who designed the satellite also witnessed the SSLV-D1 launch. The general public also witnessed the launch from the viewing gallery of Satish Dhawan Space Centre (SDSC) in Sriharikota.
SpaceX Launches South Korea’s First Lunar Orbiter Danuri on Falcon 9 Rocket
By Agence France-Presse | Updated: 5 August 2022
South Korea’s first lunar orbiter successfully launched on a year-long mission to observe the Moon, Seoul said Friday, with the payload including a new disruption-tolerant network for sending data from space.
Danuri — a portmanteau of the Korean words for “Moon” and “enjoy” — was on a Falcon 9 rocket launched from Cape Canaveral in Florida by Elon Musk’s aerospace company SpaceX. It aims to reach the Moon by mid-December.
“South Korea’s first lunar orbiter ‘Danuri’ left for space at 8:08am on August 5, 2022,” Seoul’s science ministry said in a tweet, sharing a video of the rocket blasting off trailing a huge column of smoke and flames.
“Danuri will be the first step towards the Moon and the farther universe,” it said, apparently referring to the country’s ambitious space programme, which includes plans for a Moon mission by 2030.
SpaceX tweeted that the launch had been a success.
“Deployment of KPLO confirmed,” it said, referring to Danuri using an acronym of its official name, the Korea Pathfinder Lunar Orbiter.
During its mission, Danuri will use six different instruments, including a highly sensitive camera provided by NASA, to conduct research, including investigating the lunar surface to identify potential landing sites.
One of the instruments will evaluate disruption-tolerant, network-based space communications, which, according to South Korea’s science ministry, is a world first.
BTS in space
Danuri will also try to develop a wireless Internet environment to link satellites or exploration spacecraft, they added.
The lunar orbiter will stream K-pop sensation BTS’ song “Dynamite” to test this wireless network.
Another instrument, ShadowCam, will record images of the permanently shaded regions around the poles of the Moon where no sunlight can reach.
Scientists also hope that Danuri will find hidden sources of water and ice in areas of the Moon, including the permanently dark and cold regions near the poles.
“This is a very significant milestone in the history of Korean space exploration,” said Lee Sang-ryool, head of the Korea Aerospace Research Institute, in a video shown before the launch.
“Danuri is just the beginning, and if we are more determined and committed to technology development for space travel, we will be able to reach Mars, asteroids, and so on in the near future.”
South Korean scientists say Danuri — which took seven years to build — will pave the way for the nation’s more ambitious goal of landing on the Moon by 2030.
“South Korea will become the seventh country in the world to have launched an unmanned probe to the Moon,” an official at the Korea Aerospace Research Institute told AFP.
“We hope to continue contributing to the global understanding of the Moon with what Danuri is set to find out.”
Danuri was launched by a private company — SpaceX — but South Korea recently became one of a handful of countries to successfully launch a one-tonne payload using their own rockets.
In June, the country’s homegrown three-stage rocket nicknamed Nuri — a decade in development at a cost of $1.5 billion (roughly Rs. 11,864 crore) —launched successfully and put a satellite into orbit, on its second attempt after a failure last October.
That launch — coupled with Danuri’s launch Friday — helps bring South Korea ever closer to achieving its space ambitions.
In Asia, China, Japan and India all have advanced space programmes — and the South’s nuclear-armed neighbour North Korea has also demonstrated satellite launch capability.
Ballistic missiles and space rockets use similar technology and Pyongyang put a 300-kilogram (660-pound) satellite into orbit in 2012 in what Washington condemned as a disguised missile test.
IIT-M Students Conduct First Student Council Election Using Blockchain Technology
By Press Trust of India | Updated: 4 August 2022
Students of the Indian Institute of Technology, Madras (IIT-M), here, have conducted a students council election using blockchain technology which is claimed to be the first of its kind to be used in the poll process, an official said on Thursday. Students of Webops and Blockchain Club from the Centre for Innovation (CFI), IIT-Madras, developed the software to conduct the election through the blockchain technology.
A blockchain is an unchangeable, distributed digital ledger. The transactions or records on the ledger which are stored individually are referred to as a ‘block’ and the information in a block is usually linked to the information in a previous block. This, over time, forms a chain of transactions, which is what the word blockchain refers to.
This technology can also be used by governments to improve both efficiency and traceability in the process. Back in May, the Brazilian government unveiled a blockchain network in a bid to combat corruption in public expenses by tracking them efficiently. The Brazilian Blockchain Network is still in development but will be used by a number of governmental institutions
In view of the conduct of the election, the India Book of Records presented IIT-Madras students with the record of ‘Blockchain Software for Students Body Election.’
“This student-led project has the transformative potential to positively disrupt the way elections are held. By harnessing the inherent trust and immutability offered by blockchain technologies, this work demonstrates their impact on conducting elections…” said IIT-Madras, faculty-in-charge, Webops and Blockchain Club, professor Prabhu Rajagopal.
According to the officials, some of the key advantages of using blockchain technology for elections include considerable cost reduction, offering a tamper-proof process that is verifiable and bringing an innate trust in the election process.
Elon Musk’s SpaceX Debris Discovered in Australian Sheep Paddock
By Agence France-Presse | Updated: 4 August 2022
A charred chunk of space junk found jutting from a paddock by an Australian sheep farmer was confirmed to be part of one of Elon Musk’s SpaceX missions by authorities Thursday.
The ethereal-looking debris, believed to have plummeted to Earth on July 9, was found last week in Dalgety — a remote area near Australia’s Snowy Mountains, about five hours’ drive southwest of Sydney.
“It was kind of exciting and weird all in the same way,” astrophysicist Brad Tucker, who visited the site after local farmers contacted him last month, told AFP.
He said that finding the large chunk embedded in an empty field reminded him of something out of the sci-fi film “2001: A Space Odyssey”.
“It’s astounding to see it.”
Australia’s space agency confirmed the debris had come from one of Musk’s missions in a statement and told locals to report any further finds to SpaceX.
“The Agency has confirmed the debris is from a SpaceX mission and continues to engage with our counterparts in the US, as well as other parts of the Commonwealth and local authorities as appropriate,” an Australian Space Agency spokesman said.
Tucker said the piece was part of a trunk jettisoned by the earlier Crew-1 capsule when it re-entered Earth’s atmosphere in 2021.
He said the trunk had split up on re-entry, with reports of other space junk also found at nearby properties, making more discoveries linked to the SpaceX mission likely.
Most space debris splashes down at sea but with the increase in space industries worldwide, the amount crashing to earth would likely increase, he added.
“We do have to realise that there is a likely risk it may hit in a populated area once and what that means.”
Australia’s Space Agency said it was working to mitigate debris and had raised the issue internationally.
NASA’s New Horizons Data Helps Identify a Possible Source for Pluto’s Moon Charon’s Red Cap
By ANI | Updated: 2 August 2022
Scientists combined data from NASA’s New Horizons mission with novel laboratory experiments and exospheric modelling to reveal the likely composition of the red cap on Pluto’s moon Charon and how it may have formed. This first-ever description of Charon’s dynamic methane atmosphere using new experimental data provides a fascinating glimpse into the origins of this moon’s red spot as described in two recent articles. “Prior to New Horizons, the best Hubble images of Pluto revealed only a fuzzy blob of reflected light,” said SwRI’s Randy Gladstone, a member of the New Horizons science team. “In addition to all the fascinating features discovered on Pluto’s surface, the flyby revealed an unusual feature on Charon, a surprising red cap centred on its north pole.”
Soon after the 2015 encounter, New Horizons scientists proposed that a reddish “tholin-like” material at Charon’s pole could be synthesized by ultraviolet light breaking down methane molecules. These are captured after escaping from Pluto and then frozen onto the moon’s polar regions during their long winter nights. Tholins are sticky organic residues formed by chemical reactions powered by light, in this case, the Lyman-alpha ultraviolet glow is scattered by interplanetary hydrogen molecules.
“Our findings indicate that drastic seasonal surges in Charon’s thin atmosphere, as well as light breaking down the condensing methane frost, are key to understanding the origins of Charon’s red polar zone,” said SwRI’s Dr Ujjwal Raut, lead author of a paper titled “Charon’s Refractory Factory” in the journal Science Advances. “This is one of the most illustrative and stark examples of surface-atmospheric interactions so far observed at a planetary body.”
The team realistically replicated Charon surface conditions at SwRI’s new Center for Laboratory Astrophysics and Space Science Experiments (CLASSE) to measure the composition and colour of hydrocarbons produced on Charon’s winter hemisphere as methane freezes beneath the Lyman-alpha glow. The team fed the measurements into a new atmospheric model of Charon to show methane breaking down into residue on Charon’s north polar spot.
“Our team’s novel ‘dynamic photolysis’ experiments provided new limits on the contribution of interplanetary Lyman-alpha to the synthesis of Charon’s red material,” Raut said. “Our experiment condensed methane in an ultra-high vacuum chamber under exposure to Lyman-alpha photons to replicate with high fidelity the conditions at Charon’s poles.”
SwRI scientists also developed a new computer simulation to model Charon’s thin methane atmosphere.
“The model points to ‘explosive’ seasonal pulsations in Charon’s atmosphere due to extreme shifts in conditions over Pluto’s long journey around the Sun,” said Dr Ben Teolis, lead author of a related paper titled “Extreme Exospheric Dynamics at Charon: Implications for the Red Spot” in Geophysical Research Letters.
The team input the results from SwRI’s ultra-realistic experiments into the atmospheric model to estimate the distribution of complex hydrocarbons emerging from methane decomposition under the influence of ultraviolet light. The model has polar zones primarily generating ethane, a colourless material that does not contribute to a reddish colour.
“We think ionizing radiation from the solar wind decomposes the Lyman-alpha-cooked polar frost to synthesize increasingly complex, redder materials responsible for the unique albedo on this enigmatic moon,” Raut said. “Ethane is less volatile than methane and stays frozen to Charon’s surface long after spring sunrise. Exposure to the solar wind may convert ethane into persistent reddish surface deposits contributing to Charon’s red cap.”
“The team is set to investigate the role of solar wind in the formation of the red pole,” said SwRI’s Dr Josh Kammer, who secured continued support from NASA’s New Frontier Data Analysis Program.
