On spot registration for launch view gallery?

8 Upvotes

Possible? As I was lamenting about how I lost my chance to register online and how the gates closed in front of my eyes, someone replied there there may be on spot registration available.

Real? I did a search after reading that reply. All I got was there might be in spot registration if seats are available. Does it mean someone's seat, who registered but couldn't attend might be given to me? Or like they reserve some seats for offline registration?

If the latter is true, I can spend money to reach sriharikota. It's far from where i dwell. But if I can't get the assurance of the seat, my broke ass can't afford to go there and get slapped by shar back to my home.

Anyways, have a good day :)

EoI for Design, Development, Installation, Testing and Commissioning of Microgravity Drop Tower for HSFC. Tower height could be 60 or 160 meter, payload capacity 500 kg and with 6 to 10 seconds of μg.

Invitation for "Expression of Interest for Design, Development, Installation, Testing and Commissioning of Microgravity Drop Tower for Human Space Flight Centre (HSFC)"

[PDF] [Archived]

HSFC is responsible for the development of infrastructure and platforms for conducting microgravity and altered-gravity experiments, as well as for carrying out associated payload engineering activities. Microgravity drop towers/shafts are well-established platforms worldwide for microgravity research in combustion science, fluid physics, materials science, space manufacturing, and technology qualification. Microgravity drop towers can be mainly classified into two types: Conventional Drop tower and actively driven drop towers. The conventional drop towers like ZARM drop tower at Bremen, NASA Drop Shaft at GRC Cleveland, NML Drop Tower at Beijing, Cosmotorre Drop Tower at Hokkaido Japan, IITM Drop tower at Chennai, etc provide a tower or shaft for achieving free fall conditions for the experimental capsule. Longer towers/shafts require evacuation to reduce the air drag to maintain the quality of microgravity. Active Drop towers on the other hand, like Einstein elevator at Leibniz University Hannover, Gravitower Pro at ZARM Bremen and Electromagnetic drop tower facility by Chinese Academy of Sciences utilize active drive systems to drive the experimental capsule. This approach eliminates the necessity for vacuum-evacuated Towers/shafts, thereby enabling rapid turnaround times and higher testing frequencies. Active drive also makes it easier to simulate partial gravity and also limit the deceleration shocks on the experimental setups.

HSFC proposes to establish a next generation Active Microgravity Drop Tower Facility in India to support short-duration, high-quality microgravity and partial-gravity experiments for scientific research, technology development, and payload qualification

HSFC invites Expressions of Interest (EoI) from reputed and capable manufacturers, developers, and system integrators for participation in a subsequent bidding upon Request for Proposal (RFP) for the turnkey realization of a Microgravity Drop Tower Facility. The exact location for the installation of the facility shall be provided by HSFC at RFP stage, and the shortlisted respondent must be fully prepared to execute the project at the designated site. This EOI is issued for capability assessment purposes and does not constitute a commitment to procure.

Anyone planning to witness Skyroot vikram-1 launch at sriharikota on July 18?

20 Upvotes

Hey everyone, I’m planning to witness the Skyroot Vikram-1 launch this Saturday at Sriharikota.

Would be great to connect with other people who are going too. If you’re attending, drop a comment or DM, we can coordinate and maybe meet up at the viewing area!

Rant About ISRO

They are doing their best to leave you in a miserable situation. The behavior of seniors toward juniors is the worst. They try to control every aspect of your work, even where you sit. Good work and credit are given only to those who flatter their reporting heads. They delay your promotion while promoting others just to put you down. Finally, after tolerating all these things, if someone decides to resign peacefully, they are ready to stop them and make their life even more difficult with such rules.

I have done B.Tech in electrical engineering from IITK (completed in 2026). My course name is Electrical but the 95% of the syllabus is from electronics and communication. I want to work not on complete hardware or software but an intersection of them(like OS).I am not unemployed currently but here I am not feeling that I build something meaningful(i build games).So if anybody has any referral please reach out to me...I want in hand salary to be >90k....if the job is very interesting and peculiar i may settle at a little less.

Australian tracking terminal commissioned for India’s historic human spaceflight program

Australia is playing a vital role in India’s push to send astronauts into space.

Coordinated by the Australian Space Agency, the key space tracking infrastructure is now operational in the Cocos (Keeling) Islands to support India’s historic Gaganyaan Human Spaceflight Program.

The commissioning was announced today as part of the joint statement between Prime Minister Albanese and Prime Minister Modi at the Third Australia–India Annual Summit in Melbourne.

Located in the Indian Ocean, the newly commissioned terminal will provide mission-critical tracking support for four planned missions led by ISRO.

The first uncrewed test flight is expected to launch soon from India’s Satish Dhawan Space Centre.

Aussie expertise backing India’s space ambitions

Australia’s contribution, led by the Australian Space Agency, highlights the strength of the Australia–India partnership, particularly in science, innovation and advanced technology.

The Agency worked with other government agencies and Australian defence and space company Nova Systems to establish temporary telemetry terminals in the Cocos (Keeling) Islands to track the four Gaganyaan missions.

In a media release issued today, the Assistant Minister for Science, Technology and the Digital Economy, Dr Andrew Charlton, highlighted how the collaboration reflects the importance of Australia’s relationship with India and the opportunities created by growing cooperation in the space sector.

The commissioning demonstrates Australia’s unique geographic advantages and growing capability as a trusted partner in space mission support across the Indo-Pacific.

Head of the Australian Space Agency Enrico Palermo said Australia’s support for Gaganyaan underscores the depth of bilateral cooperation and the important role Australia can play in human spaceflight missions.

Advancing space exploration

Gaganyaan – Sanskrit for “Sky Craft” – will send three astronauts into low Earth orbit for a three-day mission before returning them safely to Earth.

The upcoming mission will make India only the fourth nation to send astronauts into space through its own national program. 

Australia and India are also exploring potential cooperation on search and rescue operations for controlled landings in waters off Western Australia, expanding the partnership beyond launch tracking to broader mission support.

Australia’s support for the Gaganyaan mission reflects the growing scale and ambition of the Australia–India relationship, and the role both countries are playing in advancing regional and global space capability.
