Space / Universe / Cosmos

Gravitational equilibrium within Solar System and beyond is very intriguing, often defying the various laid down explanations. The Cosmos poses more questions than provides answers. It is more of scientists' dilemma and poetic imaginations.

This is a new technology N-capable missile with 1000-2000 Km range

Of late, there are increasing interests of re-usable technologies in the space ventures. There are reusable launch vehicles, China has already developed a reusable spacecraft and Indian interests are also working in that direction.

Space Tourism has now come to stay. Different agencies would offer different numbers of experiences…mostly offering sub-orbital flights of few minutes but some offering varying orbiting experiences too. Although the costs of the flights will vary with varying agencies offering it, it is going to be fortunes for many but some may not mind spending.

As and when Skyroot and the similar private firms fully operationalise their products and services, it will surely be a boost for India in space technologies

Looking at its small payload capability, RLV program objective seems to be unclear from the viewpoint of its economic advantages. However, it is a welcome step as a technology demonstration that could be scaled up in size to meet larger commercial objectives of carrying larger payloads, trapping or bringing back an orbiting satellite or carrying out a deep space scientific mission.

Whatever might have been the reasons behind the deviations in the manoeuvring of Chandrayaan3 till now, ISRO has handled it apparently well as a result of which, the craft is almost in place where it was ought to be.

The stage is nearly set for realising ‘Gaganyaan’ mission. Although the launch was not possible before 75th Independence Day, corners must not be cut that may jeopardise the safety of operations. As far as realising fully indigenous technologies are concerned, there will surely be Gaganyaan 2, 3, 4 and more.

the options for utilising the ISS for tourism have challenges but is certainly feasible. Will Jeff Bezos, Richard Branson or Elon Musk utilize the concept of ‘Star Hotel in Heaven’, remains to be seen. If not, they may have to modify their crafts for better comfort and luxury, for prolonged durations of ventures to orbital flights or longer flights of one or more circles of the Earth, for the tourists to be able to view Sunset/Sunrise, changing perspective of the Earth for lasting memories.

Away from the media hype of the CES test carried out reportedly successfully on 21 Oct 23, there are questions on the rationale of the Test Schedule.

All Space Tourists will have some minimum expectations of fulfilling some as mentioned above esp when you pay fortunes. In Virgin Galactic the microgravity is of limited period, space in the cabin isn’t enough to float freely. The firm isn’t trying to give you glimpses of sunrise or sunset.

With the successful launch of Chandrayaan 3 on 14 July 2023 and injecting it into the elliptical Earth’s Parking orbit, it is only the culmination of the first of ten phases successfully. Intricacies and challenges of the subsequent phases lay ahead and have to be solved/handled carefully in the coming days and weeks.

Chandrayaan 3 seems to have been taken care of all possible reasons that could have played role in the partial failure of Chandrayaan 2 soft landing.

It remains to be seen as to how the erring parties are compelled to remove the space debris caused by them. Laws also need to be framed to compensate for the damages and disruptions caused by those collisions.

While natural spoils by volcanos, are not in our hands greenhouse gasses and particulates being added up by human through aviation and space activities are inexcusable. It includes exhaust gasses, products of vehicular destruction as well as burn-out of rockets, satellitess and other junks during re-entry. It is time for the UN bodies to frame laws to prevent greenhouse effects and be firm against the spoilers without bias.

FAA has grounded falcon-9 Rocket of SpaceX following consecutive glitches. It is wishfully hoped that either SpaceX or FAA will not cut corners in clearing the rocket.

It was a wrong decision to launch the Boeing Starliner with known defect. The first task before the team is to get the astronauts back and for this, NASA / Boing must requisition another agency.

ISRO’s SpaDeX mission was launched successfully aboard PSLV C60 rocket with several payloads of both ISRO as well as other agencies/institutions. However, many questions were posed by unpredicted drifts induced in SpaDeX system that needs to be addressed.

From July 2021, people will be able to make adventure trips to sub-orbital flights...of course at a price.

Space Tourist will have some minimum expectations from the flights as mentioned in this article. The companies offering Space Tourism at the prohibitive costs in the present times, must be safe and fulfilling their expectations.

Any Adventure activity does have some inherent risks but certainly not at the cost of anyone’s life. Any Space Tourist will have some minimum expectations as mentioned in the article. The companies offering Space Adventure at the prohibitive costs equivalent to fortunes in the present times, must be safe and fulfilling their expectations. Whether Virgin Galactic fulfils all those obligations, they and their passengers will decide. This article only aims at bringing out a third party of view point.

Any new spacecraft or satellite launched in to the LEO takes just few minutes. However, sending the spacecraft for docking to the ISS hakes many hours to even couple of days. This article examines as to what should be a shortest time for the spacecrsft to dock with the ISS.

For long human development methods by developed nations ignored the basic principles of living in harmony with nature. The result is before us in the form of Climate Changes and Environmental adversities that may be reaching a stage of ‘difficult to return’.

While environmentalists the world over are rightly concerned about the climate changes, very few are aware of the multiple holes that the heavier and mightier rockets and missiles are drilling in our atmosphere as explained above. All super-powers and space agencies involved with space explorations would like to see these issues be swept under the carpet for as long as possible. Time has come when all activists of environment must come together and take effective steps unitedly so as to make our Earth, the only inhabitable planet to the best of our knowledge in the cosmos, a safer place to live. None should be allowed to damage the atmospheric cover of the Earth.
