Boeing delayed an uncrewed flight of its Starliner capsule to the International Space Station (ISS) on Tuesday over a propulsion issue, pushing back by at least a day a key test it last attempted in 2019.
The spaceship had been due to launch on an United Launch Alliance (ULA) Atlas V rocket from the Cape Canaveral Space Force Station in Florida early in the afternoon.
But just over two hours before lift-off, the company tweeted it was scrubbing the flight.
The next available launch opportunity is at 12:57pm Eastern time (10:27pm IST) on Wednesday, pending resolution of the problem.
“We’re disappointed with today’s outcome and the need to reschedule our Starliner launch,” said John Vollmer, vice president and program manager of Boeing’s commercial crew programme.
“Boeing and NASA teams will take the time they need to ensure the safety and integrity of the spacecraft and the achievement of our mission objectives.”
The test flight was supposed to take place Friday but had to be rescheduled after a new Russian science module inadvertently fired its thrusters following docking with the ISS, pushing the orbital outpost off kilter.
After NASA ended the Space Shuttle programme in 2011, it gave both Boeing and SpaceX multi-billion dollar contracts to provide its astronauts with taxi services to the space station and end US reliance on Russian rockets for the journey.
SpaceX’s programme has moved forward faster, having now undertaken three crewed missions.
Boeing’s programme is lagging behind, and needs to complete a successful uncrewed mission before it can carry astronauts.
During an initial uncrewed test flight in December 2019, the Starliner capsule experienced software glitches that caused problems with the way it fired its thrusters.
As a result, Starliner did not have enough fuel to reach the ISS and had to return to Earth prematurely, and a subsequent investigation showed it almost experienced a dire flight anomaly while reentering the atmosphere.
NASA later called the mission a “high visibility close call,” a rare designation reserved for near-catastrophes.
Steve Stich, manager of NASA’s commercial crew programme, told reporters last week he had confidence this time around.
“We want it to go well, we expect it to go well, and we’ve done all the preparations we can possibly do,” he said.
“Starliner is a great vehicle, but we know how hard it is, and it’s a test flight as well and I fully expect we’ll learn something on this test flight.”
When it flies, the spacecraft will carry more than 400 pounds (180kgs) of cargo and crew supplies to the ISS and will return more than 550 pounds of cargo, including air tanks, when it lands in the western US desert at the end of its mission.
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.
