A brand new Indian rocket efficiently delivered three satellites to orbit on Thursday evening (Feb. 9), bouncing again from its failed debut flight in August 2022.
The Small Satellite tv for pc Launch Car (SSLV) lifted off from India’s Satish Dhawan Area Centre Thursday at 10:48 p.m. EST (0348 GMT and 9:18 a.m. native time on Feb. 10), carrying the Indian Area Analysis Organisation’s (ISRO) EOS-07 Earth-observation satellite tv for pc and two ride-along cubesats skyward.
By 15.5 minutes later, the 112-foot-tall (34 meters) rocket had deployed all three (opens in new tab) spacecraft into their designated 280-mile-high (450 kilometers) round orbits, and mission crew members have been exchanging smiles and handshakes within the management room.
“With the profitable launch of the SSLV-D2/EOS-07 mission, ISRO now has a brand new credible member in its launch car household,” a commentator stated on the company’s livestream simply after the satellites deployed. “Congratulations to crew ISRO!”

It was an enormous second for ISRO and the SSLV, which is able to carrying as much as 1,100 kilos (500 kilograms) of payload to low Earth orbit. The rocket failed on its solely different flight, which lifted off from Satish Dhawan on Aug. 6, 2022.
The SSLV bumped into bother that day throughout the separation of its second stage, an motion that created a short however intense “vibration disturbance.” The shaking briefly saturated all six accelerometers within the SSLV’s navigation system, which pushed the rocket into “salvage mode,” ISRO officers defined in an replace final week (opens in new tab). (The SSLV consists of three phases topped by a kick stage that ISRO calls the Velocity Trimming Module.)
The shift into salvage mode, in flip, finally brought about the rocket to deploy its two satellites — ISRO’s EOS-02 Earth-observation craft and the student-built AzaadiSAT cubesat — into the flawed orbit. Each spacecraft have been quickly dragged again down into Earth’s environment and misplaced.

ISRO officers stated in final week’s replace that that they had carried out plenty of measures to make sure one thing related would not occur on future SSLV flights. For instance, the second-stage separation system was swapped out for a unique one which’s recognized to supply less-intense vibrations.
These fixes did the trick on Thursday’s flight, and the three satellites can now begin gearing up for orbital operations.
The 344-pound (156 kg) EOS-07 is an experimental satellite tv for pc whose mission aims middle on creating and demonstrating new devices on a brief schedule, in accordance an ISRO mission description (opens in new tab). These devices embody the Millimeter-wave Humidity Sounder and the Spectrum Monitoring Payload. EOS-07 is designed to look at Earth with that gear for at the least one 12 months.
The opposite two satellites that rode to orbit aboard the SSLV are the 22.5-pound (10.2 kg) Janus-1 and the 19.7-pound (8.7 kg) AzaadiSAT-2.
Janus-1, which was constructed by the Indian-American firm Antaris, is a technology-demonstrating “good satellite tv for pc,” in response to the ISRO mission description. Like its predecessor, AzaadiSAT-2 was constructed by a whole bunch of feminine college students from throughout India. AzaadiSAT-2 “goals to display LoRa and novice radio communication capabilities, measure radiation ranges in house and display expandable satellite tv for pc construction, and many others,” ISRO officers wrote.
