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.”
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?
