Aditya-L1 successfully undergoes the second earth-bound manoeuvre: Isro

Aditya L1, the first space based Indian mission to study the Sun underwent the second earth-bound manoeuvre successfully, during the early hours on Tuesday, ISRO said. ISRO's Telemetry, Tracking and Command Network (ISTRAC) carried out the operation. "The second Earth-bound manoeuvre (EBN#2) is performed successfully from ISTRAC, Bengaluru. ISTRAC/ISRO's ground stations at Mauritius, Bengaluru and Port Blair tracked the satellite during this operation. The new orbit attained is 282 km x 40225 km," ISRO said in a post on X (formerly Twitter). The next manoeuvre (EBN#3) is scheduled for September 10, 2023, around 02:30 Hrs. IST, it said. Aditya-L1 is the first Indian space based observatory to study the Sun from a halo orbit around first sun-earth Lagrangian point (L1), which is located roughly 1.5 million km from earth. The first earth-bound manoeuvre was successfully performed on September 3. The spacecraft will undergo two more earth-bound orbital manoeuvres before placing in th

Chandrayaan-3: Isro hoping for rover, lander 'awakening' by Sep 22

ISRO on Monday announced that Chandryaan-3 mission's Vikram lander has been put into sleep mode. The rover, Pragyan was set on the sleep mode on Saturday. "Vikram Lander is set into sleep mode around 08:00 Hrs. IST (8 am) today. Prior to that, in-situ experiments by ChaSTE, RAMBHA-LP and ILSA payloads are performed at the new location. The data collected is received at the Earth," ISRO said in an update on micro-blogging site X. The payloads were switched off and the "lander receivers are kept on." "Vikram will fall asleep next to Pragyan once the solar power is depleted and the battery is drained. Hoping for their awakening, around September 22, 2023," the space agency said. ISRO chief S Somanath had earlier said the lunar mission's rover and lander would be put to "sleep" to withstand the night on the Moon.

Four Kerala PSUs part of India's first solar exploration mission Aditya-L1

As India's first solar exploration satellite reached space, four Kerala public sector undertakings, including Keltron, have reason to be delighted as they too have contributed to this achievement by the country. Various products indigenously developed and manufactured by the four PSUs - Keltron, Steel and Industrial Forgings Limited (SIFL), Travancore Cochin Chemicals (TCC) and Kerala Automobiles Ltd (KAL) - have been used in the Aditya L1 mission. This milestone achieved by the PSUs was highlighted by state Industries Minister P Rajeev in a Facebook post. The minister said 38 electronic modules manufactured by the Kerala State Electronics Development Corporation Limited (Keltron) were used in the PSLV-C57 launch vehicle used to send the Aditya L1 satellite into space. In addition to that, Keltron also provided testing support for various types of electronics models required for the mission, he said. Rajeev further said that the forgings for the various stages of the Aditya L1 la

Woman scientist who lent her voice for ISRO countdowns no more

ISRO scientist N Valarmathi who did the countdown for a number of missions including the Chandrayaan-3 died in Chennai on September 2 following cardiac arrest, an official said here on Monday. Valarmathi died at a Chennai hospital, the ISRO official added. Chandrayaan 3 is said to be her last countdown assignment. Condolences poured in for Valarmathi, with Union Minister Rajeev Chandrasekhar among others expressing grief over her death. Many fondly recalled her resonating countdown from the Mission Control Centre at ISRO's Sriharikota spaceport during many launches. Dr P V Venkitakrishnan, former ISRO Director said "the voice of Valarmathi Madam will not be there for the countdowns of future missions of ISRO from Sriharikotta." "Chandrayaan 3 was her final countdown announcement. An unexpected demise . Feel so sad. Pranams," he said in a post on X. In his social media post, Chandrasekhar expressed grief over Valarmathi's demise. "Saddened to hear about the passing of N Valarm

Vikram lander makes soft-landing, successfully undergoes hop test: Isro

ISRO on Monday said the Vikram lander successfully underwent a hop test when it made the soft-landing again on the lunar surface. On command it (Vikram lander) fired the engines, elevated itself by about 40 cm as expected and landed safely at a distance of 30 to 40 cm away, ISRO said in an update on 'X'. Noting that the Vikram lander exceeded its mission objectives, ISRO said the importance of the exercise was that this 'kick-start' enthuses future sample return and human missions. "Vikram soft-landed on the moon, again! Vikram Lander exceeded its mission objectives. It successfully underwent a hop experiment. On command, it fired the engines, elevated itself by about 40 cm as expected and landed safely at a distance of 30-40 cm away," ISRO said in a post. "Importance?: This 'kick-start' enthuses future sample return and human missions! All systems performed nominally and are healthy. Deployed Ramp, ChaSTE and ILSA were folded back and redeployed successfully after the experiment,"

Chandrayaan-3 spacecraft successfully undergoes last Moon-bound maneouvre

India's ambitious third Moon mission's spacecraft Chandrayaan-3 on Wednesday successfully underwent a fifth and final Moon-bound orbit maneouvre, bringing it even closer to the lunar surface. With this, the spacecraft has completed its lunar-bound maneouvres and it will now prepare for the propulsion module and the lander module separation, ISRO said. "Today's successful firing, needed for a short duration, has put Chandrayaan-3 into an orbit of 153 km x 163 km, as intended. With this, the lunar bound maneuvres are completed.It's time for preparations as the Propulsion Module and the Lander Module gear up for their separate journeys," the national space agency tweeted. Separation of the lander module from the propulsion module of the spacecraft is planned for August 17, it said. Post its launch on July 14, Chandrayaan-3 entered into the lunar orbit on August 5, following which three successive orbit reduction maneouvres were carried out on August 6, 9 and 14 to move closer to the .

Chandrayaan-3 rover has completed its tasks, is set into sleep mode: Isro

Chandrayaan 3's rover 'Pragyaan' has completed its assignments on the lunar surface and set into sleep mode, ISRO said on Saturday. The space agency's announcement came hours after its chief S Somanath said the lunar mission's rover and lander, 'Pragyaan' and 'Vikram', respectively were functioning well and they would be put to "sleep" soon to withstand the night on the Moon. "The Rover completed its assignments. It is now safely parked and set into Sleep mode. APXS and LIBS payloads are turned off. Data from these payloads is transmitted to the Earth via the Lander," ISRO said in an update on social media platform X. At present, the battery was fully charged and the solar panel oriented to receive the light at the next sunrise expected on September 22, 2023. "The receiver is kept on. Hoping for a successful awakening for another set of assignments! Else, it will forever stay there as India's lunar ambassador," it said.
