Jeff Bezos created history on Tuesday when he successfully travelled to the edge of space and returned in the spacecraft developed by his company, Blue Origin. Over two decades after Bezos established the space company, he was accompanied by a crew of three others in the New Shepard spacecraft on his maiden journey to space. After the flight that lasted roughly 10 minutes, the capsule landed in West Texas at about 8:22 a.m. local time. The spacecraft made its way the Karman line — considered to be the edge of space — at an altitude of 100 kilometres above the Earth.

At the end of the journey, Bezos simply said: “best day ever!” He then added, “My expectations were high and they were dramatically exceeded.”

The billionaire was accompanied on the flight by his 53-year-old brother, Mark Bezos, 82-year-old former pilot Wally Funk, as well as an 18-year-old Oliver Daemen. The crew held the distinction of having the world’s richest, the world’s oldest and the world’s youngest persons to have visited space.

Upon hitting zero gravity, the crew was seen floating within the capsule, celebrating the experience. In awe of what she was witnessing, Funk said, “Oh my word, look at the world!” presumably looking out the window at Earth below. But it was Bezos who had viewers in splits when he was heard asking the crew, “Who wants a Skittle?”

In his first interview upon landing, Bezos said, “I am not talented enough to describe this in words,” adding that it was “beyond” what he dreamt the Earth would look like. At a loss of words to describe the spectacle he had witnessed, Bezos said, “Maybe we need to send a poet up or something. Someone who would be better at describing it.”

Speaking after the flight, Bezos said that he wanted to thank the employees and customers of Amazon, the company he founded. The former Amazon CEO said, “I want to thank every Amazon employee and every Amazon customer because you guys paid for all this. So, to every Amazon customer out there and every Amazon employee thank you from the bottom of my heart.”

When asked to sum up the experience, Bezos exclaimed, “Oh my god!” He also added that the zero-gravity experience felt “normal… so serene and peaceful… a very pleasurable experience.” He said that the most profound part of the experience was watching the Earth and that the “fragility” of the planet surprised him.

On being asked why he was investing such money in space, Bezos said, “What we are doing is building a road to space so future generations can build a future.” The aim was to “slowly over decades, to move all heavy industries and polluting industries to space to keep the planet the gem that it is.”

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

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.

Aditya L1 Solar Mission Begins Studying Energetic Particles in Solar Wind

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.
