EMISAT has been successfully placed into orbit.
PSLV will be restarted twice from now to change the orbit and inclination to place the customer satellites into their orbits.
However our primary objective has been achieved.

PS: These launches have become like serving fastfood. Not many visitors to ISRO page anymore during launches.

Yes.

That is exactly how it should be, make successful launches so commonplace that people won't even think twice about India possessing such capabilities.

Isro finally opens door for people to watch rocket launches

HIGHLIGHTS

  • Isro has built a viewing gallery in the form of a stadium which can presently accommodate around 5,000 people
  • The gallery facing the two launchpads will give a clear line of sight of the rocket and its launch
NEW DELHI:

Indian Space Research Organisation
(Isro) has finally opened its door to people who wish to catch a glimpse of spectacular launches of its multi-storeyed tall and tonnes-heavy rockets from the

Satish Dhawan Space Centre
in Sriharikota, an island in Andhra Pradesh.


Monday's liftoff of PSLV-C45 carrying a DRDO payload Emisat and 28 foreign satellites will be the first such launch which spectators can witness at the space agency's island, which is over 100km north of Chennai. The agency's move to open its high-security launch facility for people for free is on the lines of National Aeronautics and Space Administration (Nasa), which too allows people in the US to watch its space activities, including rocket launches.


The viewing gallery, built like a stadium, can accommodate around 5,000 people. The gallery faces the two launchpads and will give a clear line of sight of the rocket and its launch.






Talking to TOI, Isro chairman K Sivan said: "The new stadium set up on the island can accommodate 5,000 spectators. But as a precautionary measure, we will allow only 1,000 people for Monday's launch. As the launch is at 9.30am, the entry at the stadium will only be till 8am to avoid last-minute hassles. The gallery is located 2-3km from the launchpad and will give a clear and better view of PSLV and GSLV launches. If all goes smoothly, we will allow 5,000 people for the next launch. We will later make some changes at the stadium to accommodate 10,000."



The Isro chief, who will inaugurate the viewing gallery on Sunday, said the opening of the launch centre for the public has been part of his vision to "take Isro to people" to increase public awareness about space activities.


On the eligibility criteria, Sivan said, "Only Indian citizens and children above 10 years will be allowed entry. People have to first register themselves online at the Isro website. They also have to sign an agreement online that will make it clear that Isro won't be liable for any untoward incident at the stadium or Sriharikota launch centre. On filling up all required documents online, people will get an entry pass which they have to download, take a print and show it to security while entering the island."

On safety measures and other arrangements for visitors, Sivan told TOI, "Adequate safety systems have been placed at the stadium for the public. We have also chosen food vendors who will provide snacks to people for money. Toilet and washroom facilities have also been built. There are big screens installed at the stadium that will provide information about the launch, inside view of the space control room and post-launch space activities and the press conference."


The Isro chief said the "stadium is a part of the theme park, which will also have a museum and life-size rocket models to help visitors get a better understanding and feel of rockets".


He said Isro is taking these efforts with an objective to encourage youngsters to join the space sector and increase people's knowledge about India's advancement in space activities.
AAAAH

Thats some good use of my tax RUPEES.

Cabinet approves Rs 3,000 crore GSLV phase-4 programme for 5 launches - Times of India
Surendra Singh
2-3 minutes
NEW DELHI: The Union Cabinet has approved the Rs 3,000-crore GSLV phase-4 programme under which five geo-orbit satellites will be launched in coming three years from 2021 to 2024. The programme will enable the launch of two-tonne class satellites for geo-imaging, navigation, data-relay communication and space sciences.


Of the five launches, the launch of data relay communication satellite will be significant as it will support the country’s maiden human spaceflight or Gaganyaan programme, whose deadline is fixed in December 2021, and the country’s interplanetary mission to Mars in 2022-23. Once the Gaganyaan and the subsequent Mars spacecraft are launched, the data relay satellite will act as a communication link between the spacecraft in space and the deep space control room in Karnataka’s Byalalu.


Before the start of the phase-4 programme, Indian Space Research Organisation (Isro) has a slew of important geo missions pending under the phase-3 programme. These include the launch of a new series of remote-sensing satellite geo-imaging satellites (Gisats). Gisat-1 will be launched in September and Gisat-2 in November. Gisat will carry a geo-imager with multi-spectral (visible, near infra-red and thermal) and multi-resolution (50m to 1.5 km) imaging instruments that will enhance the country’s land mapping capabilities. The satellites will therefore have both military and civilian use.


A series of advanced satellites Gsat-20, Gsat-30 and Gsat-32, which will boost communication capabilites of the country, will also be launched by early next year. While Gsat-20 and Gsat-30, a replacement of Insat-4A, will be sent to space from French Guiana, Gsat-32 will be launched from Sriharikota. Gsat-32 will replace Gsat-6A, which was lost in space after the successful launch due to a communication failure and was meant to mainly serve ground forces.


The Rs 2,729-crore budget for the GSLV ph-4 programme includes the cost of five GSLV rockets, essential facility augmentation and programme management. Two satellites will be launched every year with maximum participation by the Indian industry in the production of the country’s heavy-lift rocket.

So, its confirmed that (unfortunately) manned Gaganyaan won't lift off before 2025.
IDRSS are to be launched between 2021-24 and third launch pad won't be ready before 2023. Infrastructure isn't complete there to launch a human mission.

Another bad, Chandrayaan-2's lander Vikram has broken its legs during tests. The project has been put on hold for rectification and may he easily delayed by 6 months-1 year. Anyways, a delayed mission is better than a failed mission.

Super flares in Nascent Sun: Evidence from Meteorites!
Scientists at Physical Research Laboratory, Ahmedabad working in collaboration with University of Heidelberg, Germany,have recently reported Giant flares from the embryonic Sun. The super-flare has been calculated to be about a million times stronger in intensity compared to the highest X-class flare observed from the modern Sun.
The work is published in Nature Astronomy -
https://www.nature.com/articles/s41550-019-0716-0).
The origin and early evolution of the Solar system has remained one of the most intriguing questions for a long time. Numerous experimental and theoretical approaches have been employed to seek an unequivocal answer to this question. Owing to their unique chemistry and nearly pristine nature, meteorites constitute the most important accessible component of the Solar system material that may be analysed to unfold the story of the origin and early evolution of the Solar system.
The most widely accepted model for the formation of the Solar system suggests that the gravitational collapse of a dense molecular cloud fragment about 4.56 Ga (Giga annum, meaning billion years) ago led to the formation of the proto-Sun at its centre and a rotating disk of gas and dust, the so called Solar nebula, surrounding the nascent sun. The Solar system objects (planets, satellites, comets and asteroids) formed out of this nebula in a gradual manner starting with the formation of grains that coagulated to form larger-sized objects that evolved to planetesimals and finally to planets through gravitational interactions and collisional accretion processes. These events and processes were highly energetic, stochastic and occurred on a relatively short time scale of a few 100 kilo (thousand) years.
Experimental records that provide clues to the various issues related to the formation of the Solar System are expected to be present in the first solids that formed in the Solar system known as Calcium, Aluminum-rich Inclusions (CAIs). Identification of such early formed Solar system objects and study of their isotopic and elemental compositions using secondary ion mass spectrometry (ion microprobe) technique allows us to find answers to some of the aforesaid questions.
Study of the Efremovka meteorite has revealed unequivocal evidences of the former presence of a few now-extinct short-lived radionuclides (e.g. 26Al, 41Ca, 53Mn, 60Fe, 107Pd, 182Hf, 129I, 244Pu) with half-lives ranging from 105to ~108years in the early Solar system. The former presence of these short lived radionuclides can be inferred by looking for excess in the abundances of their daughter nuclides in suitable meteorite samples. If this excess in daughter nuclide correlates with the stable isotope abundance of the parent element, it can be attributed to the in-situ decay of the short lived nuclide within the analyzed sample, thereby confirming the presence of the nuclides at the time of formation of the object.
It is important to identify the exact source of the short-lived nuclides present in the early Solar system to determine the physio-chemical / cosmo-chemical environment during the birth of the Solar system, which begetted the ‘unique’ grand architecture of our Solar system hosting a life sustaining planet Earth. If the short-lived nuclides were injected into the proto solar molecular cloud from a stellar source, their presence in early Solar system solids puts a very strong constraint on the time interval between the production of these nuclides in the stellar source and the formation of the early Solar system solids and hence on the time scale of proto solar cloud collapse. On the other hand, if the short-lived nuclides are the products of Solar energetic particle interactions with material in the Solar nebula, they cannot be used as time markers of pre-Solar processes (e.g. time scale for proto-Solar cloud collapse). Their presence provides us specific information about the energetic environment in the early Solar system.
The 7Be, that decays to 7Li with a half-life of 53.06 ± 0.12 days, is a unique short-lived now-extinct radionuclide to derive information about the energetic environment in the early Solar system. The first unambiguous detection of 7Be along with fossil records of 10Be corresponding to 7 Be/9 Be of (1.2±1.0) ×10-3 (95% conf.) and 10Be/9 Be of (1.6±0.32)×10-3 has been inferred from the regression of the in situ isotopic data obtained using secondary ion mass spectrometer in a pristine type of CAI from Efremovka.
Isotopic records of 7 Be, 10Be and 26Al in this CAI allow us to make the following very important inferences: (1) The nascent Sun underwent multiple episodes of enhanced magnetic activity (2) the later episode of enhanced irradiation occurring at the end of “class I” stage of pre-main sequence evolution was more intense (3) Irradiation is the prime source of 7Be and also 10Be. An intense irradiation by a super flare (X-ray luminosity Lx ≈ 1032 ergs) during the terminal class I stage of a CI (carbonaceous Ivuna ≈ Solar) composition precursors near the reconnection region for about a year can concurrently explains the isotopic properties (7Be, 10B, 26Al), morphology (texture, modal grain sizes), and petrology (mineral compositions) of CAI, along with preservation of faster diffusing lithium isotope records.
These restrictive inferences have important consequences for experimental and theoretical studies in the fields of astronomy, astrophysics, planetary science, nuclear physics, experimental petrology which significantly advance our current understanding of the formation and early evolution of the Solar system. Several interesting questions arise from this study, for e.g., did such million times stronger X-flare event compared to contemporary Sun occurred earlier and later in history of the Solar system and if yes, when and why/ why not? What mechanism transported these solids to a distance of a few astronomical units (1.5 × 1011m) in a short time period of about a year? What were the consequences and imprinted isotopic signatures of these extreme events on the existing solids and gases?
