Isro gears up for Gaganyaan mission's 1st abort test of crew escape system

ISRO plans to undertake an inflight abort test of the crew escape system by this month-end using a test vehicle developed as part of the country's ambitious maiden human spaceflight venture Gaganyaan. "Preparations are going on. All vehicle systems have reached Sriharikota (for the launch). Final assembly is progressing. We are getting ready for launch by the end of October," Director of Vikram Sarabhai Space Centre (VSSC) S Unnikrishnan Nair told PTI on Thursday. "(With) this crew escape system, we will demonstrate (validate) in different conditions like high dynamic pressure and for transonic conditions," Nair added Thiruvananthapuram-based VSSC is the lead centre of ISRO under the Department of Space. An ISRO official said the crew escape system (CES) is the most important element in Gaganyaan. According to ISRO officials, this month's launch of the test vehicle TV-D1 would be the first of the four abort missions of the Gaganyaan programme. It would be followed by the second te

Adtya-L1 spacecraft successfully escapes sphere of Earth's influence: Isro

ISRO said on Saturday the Aditya-L1 spacecraft has travelled beyond a distance of 9.2 lakh km from Earth, successfully escaping the sphere of Earth's influence. It is now navigating its path towards the Sun-Earth Lagrange Point 1 (L1), the Bengaluru-headquartered national space agency said in a statement on X, formerly Twitter. "This is the second time in succession that ISRO could send a spacecraft outside the sphere of influence of the Earth, the first time being the Mars Orbiter Mission," it said. The ISRO said earlier this month the Aditya-L1 solar mission spacecraft has commenced collecting data which will help scientists analyse the behaviour of particles surrounding Earth. Data collected around L1 would provide insights into the origin, acceleration, and anisotropy of solar wind and space weather phenomena, it said. The launch of Aditya-L1 by PSLV-C57 rocket was successfully accomplished by ISRO on September 2. Aditya-L1 spacecraft carries a total seven different payloads

Isro excels as no individual here is penalised for failures, says Somanath

Failures are a very natural part of the space sector but no individual is penalised for it at ISRO which encourages scientists to take novel approaches in decision-making, the space agency's chairman S Somanath said on Wednesday. Speaking at the 50th anniversary of the All India Management Association (AIMA), Somanath, who played a key role in the soft-landing of a spacecraft on the moon, noted that even he had faced failures several times, but never got criticised for it by his seniors. "We make sure that no single individual is penalised for failures because no decision is made by a single individual. All these decisions are taken by collective wisdom," he said in an interactive session here. Somanath said in the space sector, there is a clear understanding that one person cannot understand everything which leads to collective decision-making. "So, collective decision means that you own the responsibility of failures as well. Management owns the responsibility, it is not fixed on

Aditya L1 takes STEPS to collect info on energetic particles from space

After India's solar mission Aditya L1 began its journey towards Lagrange point 1 following a key manoeuvre, it has started studying energetic particles in the solar wind from space, and will continue to do so for the rest of its life, a senior astrophysicist said. The study of the solar wind, the continuous flow of charged particles from the sun which permeates the solar system, will be carried out with the help of a device named Supra Thermal & Energetic Particle Spectrometer (STEPS), a part of the Aditya Solar wind Particle EXperiment (ASPEX) payload. STEPS is now working from space. However, it was not sitting idle earlier. It has started functioning from within the magnetic field of the Earth since September 10 when Aditya was 52,000 kilometres above our planet, Dr Dibyendu Chakrabarty, professor of Space and Atmospheric Sciences at the Physical Research Laboratory (PRL) said. STEPS was developed by the PRL with support from the Space Application Centre (SAC) in ...

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. Somanath had earlier in the day said the rover has moved almo

Aditya-L1 could help India prepare for climate change: Ex-Isro chief Nair

With the successful launch of India's first solar mission Aditya-L1, the country could develop some prediction models and prepare a resilience plan to combat climate change, former ISRO chairman G Madhavan Nair said here on Saturday. Sharing his excitement shortly after the successful takeoff of PSLV-C57, carrying the Aditya satellite from Sriharikota, Nair said it is very important to study the solar surface to understand various phenomena that instantaneously affect our local weather conditions. "Long-term variability of solar radiation also is a very important factor in the study of climate change. So, in all these areas, fundamental knowledge will be acquired through this unique mission," Nair told PTI. He said from the expected final destination of the satellite, Lagrange Point 1 (L1), the satellite could observe the Sun round the clock and extract exact data regarding various solar phenomena. "We can only try to have some (prediction) models, and the models can be validated .

Isro achieved another big milestone in space research: CM KCR on Aditya-L1

Expressing delight over the successful launch of Aditya-L1, India's first solar mission, Telangana Chief Minister K Chandrashekhar Rao on Saturday said ISRO achieved another big milestone in the field of space research. ISRO on Saturday launched the Aditya-L1, eyeing history again after its successful lunar expedition, Chandrayaan-3, a few days ago. The Chief Minister said the achievement by the India's scientists in the field of space research stood as a role model for the world and it is a proud moment for every Indian, a release from the Chief Minister's office said. Rao, also known as KCR, said that ISRO achieved another big milestone in the field of space research. KCR congratulated the ISRO Chairman, scientists and other technical staff, the release added.

Aditya L1 will study solar quakes as they affect geomagnetic field: IIA

Ahead of India's Aditya-L1 solar mission, a top scientist said the monitoring of the Sun on a 24-hour basis is a must to study solar quakes which can alter the geomagnetic fields of earth. The Aditya-L1 mission to study the Sun is slated to be launched at 11.50 am from the Sriharikota spaceport on Saturday. Explaining the need to study the Sun, Professor and In-Charge Scientist at the Indian Institute of Astrophysics (IIA), Dr R Ramesh told PTI that just as there are earthquakes on Earth, there are something called solar quakes - called as Coronal Mass Ejections (CMEs) - on the surface of the Sun. In this process, millions and millions of tons of solar materials are thrown into the interplanetary space, he said, adding these CMEs can travel at a speed of approximately 3,000 km per second. "Some of the CMEs can also be directed towards the Earth. The fastest CME can reach near Earth space in approximately 15 hours," Dr Ramesh pointed out. On why this mission was different from othe
