The first Earth-bound shift was carried out on Sunday, one day after the Indian Space Research Organisation (ISRO) successfully launched India’s first solar mission, Aditya-L1. The country’s first solar mission, Aditya-L1, is healthy and functioning normally, the space agency added.

Taking to X, formerly known as Twitter, ISRO tweeted, that the first Earth-bound maneuvre (EBN#1) is performed successfully from ISTRAC, Bengaluru. The tweet further said, the new orbit attained is 245km x 22459 km. ISRO in its tweet also revealed that the next manoeuvre (EBN#2) is scheduled for September 5, 2023, around 03:00 Hrs. IST.

Aditya-L1, India’s first solar mission, was successfully launched from Sriharikota on Saturday. Aditya-L1 is the first space-based observatory to study the sun, according to the ISRO. The spacecraft will be placed in a halo orbit around the Lagrange point L1, which is thought to be closest to the sun, after travelling approximately 15 lakh km from Earth over 125 days.

There are five Lagrange spots between the earth and the sun, named for the Italian-French mathematician Joseph-Louis Lagrange, where a small object will remain if placed there.

At this instant, the centripetal force required for a small object to travel with the Earth and the sun is equal to their combined gravitational pull.

Using onboard propulsion, the spacecraft would be directed towards the Lagrange L1 point so that it can cruise there after leaving the earth’s gravitational Sphere of Influence. Later, it would be launched into a huge halo orbit near the Sun’s L1 point.

According to ISRO, the Aditya-L1 Mission would take roughly four months to complete the entire journey from launch to the L1 point.

ISRO cited the Sun’s emission of radiation in practically all wavelengths, as well as a variety of energetic particles and magnetic fields, as justification for studying it.

Air India sacks Phuket-Delhi flight pilot after failing drug test

Air India has terminated the Phuket-Delhi flight pilot after a confirmatory test found a psychoactive substance following the August 4 incident.

Air India has terminated the employment of the pilot-in-command of a Phuket-Delhi flight after he tested positive for a psychoactive substance.

The pilot was in command of flight AI2379, which was travelling from Phuket to Delhi on August 4 when the aircraft suddenly lost altitude over Odisha. The incident left 24 passengers injured.

Air India said the termination was in line with its zero-tolerance policy regarding safety violations and regulatory requirements.

Air India terminates pilot with immediate effect

In a statement, the Tata-owned airline said the pilot-in-command had tested positive for a psychoactive substance.

The airline said that, considering its zero-tolerance approach to violations related to safety, fitness and regulatory requirements, the pilot’s employment had been terminated with immediate effect.

Air India also said it continues to cooperate fully with the investigation into the incident and has provided access to relevant operational, maintenance and technical records.

What happened on the Phuket-Delhi flight?

According to the preliminary findings of the Aircraft Accident Investigation Bureau (AAIB), the Airbus A320 was carrying 145 people when it experienced the near-simultaneous loss of all three hydraulic systems while cruising at around 36,000 feet.

The technical failure resulted in the autopilot disconnecting and triggered a brief stall warning. The aircraft subsequently lost altitude, resulting in injuries to 24 passengers.

The preliminary report also noted that the pilot tested non-negative for a psychoactive substance in a confirmatory test.

However, the report did not establish that the pilot’s drug-test result caused or contributed to the hydraulic system failure or the subsequent loss of altitude.

AAIB recommends action over psychoactive substance finding

The AAIB described the confirmation of psychoactive substance use as a serious concern and recommended that the Directorate General of Civil Aviation (DGCA) take appropriate action against the pilot on priority.

The investigation into the technical and other aspects of the incident is still underway.

The preliminary report also noted that the co-pilot was flying the aircraft when the incident occurred and attempted to bring the situation under control.

Air India said safety remains its highest priority and that its pilots undergo training, proficiency checks, medical examinations and other regulatory assessments in accordance with applicable requirements.

India has offered forensic laboratory support to help identify people who remain missing after the devastating flash floods in Nepal.

The Ministry of External Affairs (MEA) said central and state forensic laboratories in India will make their DNA profiling facilities available for first-degree biological relatives of people missing after the August 26 flash floods in Nepal.

DNA samples can be provided by relatives in India

According to the MEA, first-degree biological relatives living in India can have their biological samples collected and DNA profiles prepared.

The relatives can include a person’s father, mother, son, daughter or sibling. DNA profiling can be carried out at Central Forensic Science Laboratories (CFSLs), State Forensic Science Laboratories (SFSLs), laboratories of the National Forensic Sciences University (NFSU), and NABL-accredited laboratories with DNA profiling capabilities.

The initiative is intended to support Nepal’s ongoing process of identifying mortal remains recovered after the flash floods.

DNA profiles to be compared with unidentified remains

The MEA said the DNA profiling may use Autosomal STR DNA profiling, as advised by Nepal Police, subject to the technical requirements communicated by the Nepali authorities.

Once prepared, DNA profiles and the preliminary information required by Nepalese authorities can be sent to Nepal Police by email for comparison with DNA profiles obtained from unidentified mortal remains.

The Indian Embassy in Kathmandu will also facilitate coordination, with copies of the DNA profiles to be shared with the embassy for this purpose.

Nepal flood death toll rises

The death toll from the flash floods has risen to at least 1,259, according to Nepalese authorities, after rescue workers recovered additional bodies from affected areas.

More than 12,000 people have been rescued, while around 5,000 people remain missing as search and rescue operations continue.

The flash floods, which followed an ice-rock avalanche near the Nepal-Tibet border, caused extensive destruction across towns and villages in northern and central Nepal.
