Fresh off its success at the moon, India is now headed for the sun.
The nation launched its first-ever solar observatory today (Sept. 2), sending the Aditya-L1 probe skyward atop a Polar Satellite Launch Vehicle (PSLV) from Satish Dhawan Space Centre at 2:20 a.m. EDT (0620 GMT; 11:50 a.m. local India time).
After a series of checkouts, it will use its onboard propulsion system to head toward Earth-sun Lagrange Point 1 (L1), a gravitationally stable spot about 1 million miles (1.5 million kilometers) from our planet in the direction of the sun.
That destination explains the latter part of the mission’s name. And the first part is simple enough: “Aditya” translates to “sun” in Sanskrit.
The 3,260-pound (1,480 kilograms) observatory will arrive at L1 about four months from now, if all goes according to plan. But the long trek will be worth it, according to the ISRO.
“A satellite placed in the halo orbit around the L1 point has the major advantage of continuously viewing the sun without any occultation/eclipses,” ISRO officials wrote in an Aditya-L1 mission description. “This will provide a greater advantage of observing the solar activities and its effect on space weather in real time.”

So what’s up with all the arms on their towers? I can’t find anyone else talking about it, and I’m pretty sure other countries use a smaller number.
inb4 someone responds with a Hindu joke. Seriously, I’m wondering what the technical reason is.
If you look at the image linked below you can see some arms in the closed position with a hole in the middle where the rocket can stand. They are just used as a platform to join various stages of the rockets.

Prior to launch, these arms are just opened up as seen in the original post.
Oh, so I guess it’s to save the bit where they have to tilt the rocket upright, then. Well, clearly it works!
All I know is the Shiva joke answer; sorry.
It’s okay, you tried, I love you anyway.
I’m glad India is moving forward even if the rest of the world is moving backward and collapsing in on itself. I’m glad at least one damn country on this Earth has its priorities straight.
You know India has a right-wing nationalist government, right? And the Hindu nationalists are oppressing the other minority ethnic groups?
Pretty much every country’s science program is moving in the right direction, including the US, China, and Russia. It’s not a country problem, it’s a political problem.
Let’s think about what happened with Russia’s lander and what they have been wasting their time doing the past year and a half.
And the U.S. too, honestly. We reject education here. Even China is grinding to a halt but for other reasons. The other major powers are stagnating while India is growing, and the reasons differ from country to country, but there’s a common thread amongst all of them and that common thread is where their priorities lie.
I feel like it’s driven mostly by other factors, actually. Every country mentioned has a regressive political zeitgeist, India just has a lower level of development to start with and a great geopolitical position with the West, where all the advanced industry and most of the money is.
Failures happen. Not all the US probes have been successes, either. For example, the Mars Climate Orbiter failed. But even as governments act idiotically, science programs try to keep working. The Russian astronauts try to put aside what their government is doing and continue cooperation on the ISS. India’s space program is growing just like China’s. They’re not doing anything different or special.
Shh, just look at the pretty rockets. Nothing is happening in Kashmir. /s
This is a fair point, and well-made.
🤔 It also raises the question of how the fuck India is so successful despite its genocide attempts as opposed to the other three.
On the space program? Well, let’s not get too excited, besides the difficult landing site this was baby steps, it’s a very simple rover, and they’ve blown up their fair share of rockets. The US is still king, with the Europeans in second.
But we in the U.S. are regressing. We don’t even have a fucking Moon rover, but India now does and China has one on the far side of the Moon. Sure, we have SpaceX, but Elon Musk is a fucking twit, and the Starship he’s building is having problems.
Meanwhile India is the tortoise beating the three hares and it’s pretty obvious watching it.
I mean, the NASA is pretty serious about doing manned missions in the next few years. They have the capsule and the astronauts ready to go already and everything. Not to mention the giant Mars rovers, the deep space probes, that probe that dips into the sun and the space telescope that’s rewriting the history of the universe as we speak.
After like what, 50 years of sitting around with ther thumbs up their asses? And we still need a private company to send people to the space station we helped build? Nah, fuck that. I concede NASA has finally got off its ass to do actual work the past few years, but its cowardice has led us to disaster. We are decades behind where we should be. We should have had people on Mars in the 80’s and 90’s and should be trying to go to Titan by now.
Did you miss Parker Solar Probe, Perseverance/Ingenuity, JWST, and DART?
Didn’t we need Europe’s and Canada’s help to build the JWST?
Most space programs are international cooperations, yes.
Who helped India with Chandrayaan-3 then? Because the most the ESA and NASA have been doing for them is a quid pro quo type of program where they help each other track each other’s probes. India built their shit on their own. NASA needed Europe to help build the JWST, not just help launch it, and even then it was way behind schedule and over budget. India launched and landed their probe on a budget smaller than the movie Interstellar, so who’s really ahead in the space game here?
Everyone helped. Each new program is built on the results of the last ones, regardless of who launched them. ISRO itself started out with a Soviet partnership with Interkosmos. And as you noted, everyone cooperates in coordinating their programs in tracking and other aspects.
If you want to know about Chandrayaan-3 specifically, it looks like one of the scientific payloads was built by NASA.
Did I miss India annexing Europe and Canada?
I wouldn’t call this observatory a “sun probe” because the L1 point is still 0.99 AU from the sun. For comparison, the Parker Solar Probe is expected to reach 0.046 AU.
