NEW DELHI : The In­dian Space Re­search Or­gan­i­sa­tion has in­vited in­ter­na­tional pro­pos­als for sci­en­tific pay­loads for its sec­ond in­ter­plan­e­tary mis­sion to Venus in mid-2023, which is planned within a year of the first planned hu­man space­flight mis­sion in 2022. In­dia will send 12 sci­en­tific pay­loads aboard the satel­lite for the mis­sion.

The In­dian Space Re­search Or­gan­i­sa­tion (Isro) has in­vited in­ter­na­tional pro­pos­als for sci­en­tific pay­loads for its sec­ond in­ter­plan­e­tary mis­sion to Venus in mid-2023, which is planned within a year of the first planned hu­man space­flight mis­sion in 2022.

In­dia will send 12 sci­en­tific pay­loads aboard the satel­lite for the Venus mis­sion, in­clud­ing a ther­mal cam­era, mass spec­trom­e­ter and cloud mon­i­tor­ing cam­era.

The fi­nal space­craft is likely to have a pay­load ca­pac­ity of close to 100 kg, with 500W of power, ac­cord­ing to the Isro web­site.The satel­lite is likely to be launched into a highly-in­clined or­bit of 500x60,000 km around Venus. The apoap­sis, or the point when the satel­lite is fur­thest away from Venus, will grad­u­ally re­duce over sev­eral months. Venus is con­sid­ered to be Earth’s “twin sis­ter” be­cause of sim­i­lar­i­ties in size, mass, den­sity, com­po­si­tion and grav­ity.

The mis­sion will fo­cus on study­ing the sur­face and the sub-sur­face of the planet, at­mo­spheric chem­istry, and the in­ter­ac­tions with so­lar ra­di­a­tion or so­lar winds.

“This is the nat­u­ral pro­gres­sion for Isro. For years, In­dia’s space mis­sions fo­cussed on its lo­cal and eco­nomic us­abil­ity. If the or­gan­i­sa­tion has to progress and com­pete with other ma­jor space pro­grammes, it will have to look at pure ex­ploratory mis­sions like Chandryaan and Man­galyaan,” said Ra­jeswari Pil­lai Ra­jagopalan, head of the Nu­clear and Space Pol­icy Ini­tia­tive at Ob­server Re­search Foun­da­tion.

“This will es­tab­lish Isro’s im­age as a low-cost launcher and to ad­dress ca­pac­ity deficit in Isro’s for cater­ing to the com­mer­cial needs, it will help to open up the space sec­tor for col­lab­o­ra­tions with pri­vate play­ers us­ing tried and tested launch ve­hi­cles like the PSLV,” she said.

Isro has also in­vited pro­pos­als for ex­per­i­ments to be con­ducted on a mi­cro­grav­ity plat­form aboard its hu­man space­flight pro­gramme.

The ex­peri- ments will be con­ducted re­motely at an or­bit of nearly 400 kms from earth, ei­ther in­side an en­clo­sure with earth-like tem­per­a­ture and pres­sure or out­side it.
