A brand new Indian rocket efficiently delivered three satellites to orbit on Thursday night time (Feb. 9), bouncing again from its failed debut flight in August 2022.
The Small Satellite tv for pc Launch Automobile (SSLV) lifted off from India’s Satish Dhawan House Centre Thursday at 10:48 p.m. EST (0348 GMT and 9:18 a.m. native time on Feb. 10), carrying the Indian Space Research Organisation‘s (ISRO) EOS-07 Earth-observation satellite 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 staff members had 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 mentioned on the company’s livestream simply after the satellites deployed. “Congratulations to staff 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 hassle that day in the course of 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 update last 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 improper orbit. Each spacecraft had been quickly dragged again down into Earth’s atmosphere and misplaced.

ISRO officers mentioned in final week’s replace that that they had carried out quite a few 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 special one which’s identified 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 whose mission goals heart on growing and demonstrating new devices on a brief schedule, in accordance an ISRO mission description (opens in new tab). These devices embrace the Millimeter-wave Humidity Sounder and the Spectrum Monitoring Payload. EOS-07 is designed to look at Earth with that gear for at the very 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,” based on the ISRO mission description. Like its predecessor, AzaadiSAT-2 was constructed by tons of of feminine college students from throughout India. AzaadiSAT-2 “goals to show LoRa and novice radio communication capabilities, measure radiation ranges in space and show expandable satellite construction, and so on,” ISRO officers wrote.
