NASA Shares Statement on James Webb Space Telescope Launch Readiness: On Schedule for Post-October 31 Take Off
NASA’s long-awaited flagship observatory — the James Webb Space Telescope — is slated for take-off after October this year, as the space agency continues its talks with the European Space Agency (ESA) to fix a final launch date. This comes after their initial announcement in July last year in which the Webb Telescope was due for take-off on Halloween, October 31, 2021. According to NASA, the launch of the Webb Telescope is being tentatively planned “approximately four months after the first launch of the Ariane 5” that is slated for late July. Ariane 5 is the rocket on which the Webb telescope will be launched.
To ensure a safe take-off for the telescope, two Ariane 5 launches have been scheduled before the final launch of the telescope from the spaceport in French Guiana. In August, the Webb Telescope will be shipped to the launch site, post which a minimum of two months will be set aside for the launch processing.
According to a NASA statement, the observatory has completed all the post-environmental testing deployments, and it is in its final integration and folding stages.The mission “remains on schedule for a launch readiness date no earlier than October 31, 2021.”
The James Webb Space Telescope is garnering a lot of attention among space enthusiasts who are in deep anticipation of the studies and findings that this telescope will facilitate. Work on this telescope was initiated back in 1997 for a launch that was expected to happen in 2007. However, extensive testing and technical glitches have delayed the launch by more than a decade, leaving the space community in deeper anticipation for its take-off this year.
According to NASA, this is the “largest space telescope ever built.”

The excitement surrounding the Webb is not without reason. Going by NASA’s own words, the James Webb Telescope will study the origins of our universe, and help scientists unravel the mystery behind the creation of solar systems including our own.
The Webb, with its longer wavelength coverage and enhanced sensitivities, will complement the Hubble Space Telescope in getting a closer look at “the beginning of time,” helping scientists study the creation of the first-ever galaxies. It will also help scientists look through dust clouds in order to study the luminaries and cosmic bodies being born today.
Aditya L1 Solar Mission Begins Studying Energetic Particles in Solar Wind
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 Ahmedabad.
“During the travel time of four months (till Aditya L1 reaches its destination), it will study energetic particles in the solar wind. The data will help maintain the health and performance of our space assets in a better way,” Dr Chakrabarty told PTI.
The key aim of STEPS is to study the environment of energetic particles from the spacecraft’s position on the L1 point till it will function, he said. “The data from STEPS in the long term will also help us understand how space weather changes,” the space scientist said.
STEPS comprises six sensors, each observing in different directions and measuring supra-thermal and energetic ions. The data collected during the Earth’s orbits helps scientists to analyse the behaviour of particles surrounding the planet, especially in the presence of its magnetic field.
Aditya-L1, launched by the Indian Space Research Organisation (ISRO) on September 2, will go up to the First Lagrangian point, about 1.5 million km from the Earth ISRO on September 18 said on X: “Off to Sun-Earth L1 point! The Trans-Lagrangean Point 1 Insertion (TL1I) manoeuvre is performed successfully. The spacecraft is now on a trajectory that will take it to the Sun-Earth L1 point.” Lagrangian points are where gravitational forces, acting between two objects, balance each other in such a way that the spacecraft can ‘hover’ for a longer period of time.
The L1 point is considered the most significant of the Lagrangian points, for solar observations, which were discovered by mathematician Joseph Louis Lagrange.
Elon Musk’s Neuralink Receives Approval to Start Brain Implant Human Trial
Billionaire entrepreneur Elon Musk‘s brain-chip startup Neuralink said on Tuesday it has received approval from an independent review board to begin recruitment for the first human trial of its brain implant for paralysis patients.
Those with paralysis due to cervical spinal cord injury or amyotrophic lateral sclerosis may qualify for the study, it said but did not reveal how many participants would be enrolled in the trial, which will take about six years to complete.
The study will use a robot to surgically place a brain-computer interface (BCI) implant in a region of the brain that controls the intention to move, Neuralink said, adding that its initial goal is to enable people to control a computer cursor or keyboard using their thoughts alone.
The company, which had earlier hoped to receive approval to implant its device in 10 patients, was negotiating a lower number of patients with the US Food and Drug Administration (FDA) after the agency raised safety concerns, according to current and former employees. It is not known how many patients the FDA ultimately approved.
Musk has grand ambitions for Neuralink, saying it would facilitate speedy surgical insertions of its chip devices to treat conditions like obesity, autism, depression and schizophrenia.
In May, the company said it had received clearance from the FDA for its first-in-human clinical trial when it was already under federal scrutiny for its handling of animal testing.
Even if the BCI device proves to be safe for human use, it would still potentially take more than a decade for the startup to secure commercial use clearance for it, according to experts.

ISRO’s Aditya-L1 Performs TL1I Manoeuvre, Set to Reach Sun-Earth L1 Point
The Indian Space Research Organisation (ISRO) announced on Tuesday that its maiden solar mission — Aditya-L1 — has performed the Trans-Lagrangean Point 1 Insertion (TL1I) manoeuvre successfully and the spacecraft was now in a trajectory that will take it to the Sun-Earth L1 point. ISRO also informed that it marked the fifth consecutive time that the ISRO had successfully transferred an object on a trajectory toward another celestial body or location in space.
A post on the ISRO official handle on social media platform X read, “Aditya-L1 Mission | Off to Sun-Earth L1 point | The Trans-Lagrangean Point 1 Insertion (TL1I) manoeuvre is performed successfully. The spacecraft is now on a trajectory that will take it to the Sun-Earth L1 point. It will be injected into an orbit around L1 through a manoeuvre after about 110 days. This is the fifth consecutive time ISRO has successfully transferred an object on a trajectory toward another celestial body or location in space.”
Earlier, a launcher carrying the Aditya-L1 spacecraft blasted off from the Satish Dhawan Space Station at Sriharikota in Andhra Pradesh. The primary objectives of India’s maiden solar mission include collecting scientific data and marking another milestone in India’s solar exploration efforts.
The agency had earlier posted on X, “Aditya-L1 Mission: Aditya-L1 has commenced collecting scientific data. The sensors of the STEPS instrument have begun measuring supra-thermal and energetic ions and electrons at distances greater than 50,000 km from Earth. This data helps scientists analyze the behaviour of particles surrounding Earth. The figure displays variations in the energetic particle environment, collected by one of the units.”
The Supra Thermal and Energetic Particle Spectrometer (STEPS) instrument, a part of the Aditya Solar Wind Particle Experiment (ASPEX) payload, also started its data-gathering operations earlier.
