Orbit of Chandrayaan-2’s lander lowered, one step closer to Moon landing

New Delhi, Sept 3: The orbit of Chandrayaan-2's landing module 'Vikram' was successfully lowered for the first time on Tuesday and one final manoeuvre remained for India to pull off a historic soft-landing on the moon in the early hours of Saturday.

The 4-second de-orbiting operation was undertaken a day after the indigenously developed lander was separated from Chandrayaan-2's orbiter in a major milestone pushing India's second lunar mission into its last and most crucial leg--a controlled, soft-landing on the Moon.

The propulsion system on-board the lander was fired for the first time to lower its orbit after it started orbiting the moon independently, said the Indian Space Research Organisation(ISRO).

So far, all operations in the journey to the moon were carried out by the main orbiter of the 3,840-kg Chandrayaan-2 spacecraft that was launched into the earth's orbit on July 22 by the country's Geosynchronous Satellite Launch Vehicle, GSLV MkIII-M1.

The ISRO will perform one more de-orbiting manoeuvre on Wednesday, before the powered descent of 'Vikram' on September 7 for its landing in the lunar south pole.

A successful landing will make India the fourth country after Russia, the US and China to achieve a soft landing on the moon. But it will be the first to launch a mission to the unexplored south pole of the Moon.

"The first de-orbiting manoeuvre for Chandrayaan-2 spacecraft was performed successfully today (September 03, 2019) beginning at 0850 hrs IST as planned, using the onboard propulsion system. The duration of the manoeuvre was 4 seconds," the ISRO said giving the latest update on the Rs 978 crore Chandrayaan-2 mission.

"The orbit of 'Vikram' Lander is 104 km x 128 km. Chandrayaan-2 Orbiter continues to orbit the Moon in the existing orbit and both the Orbiter and Lander are healthy," it said, adding that the second and final manoeuvre to further lower the orbit is scheduled on September 4 between 3.30 and 4.30 am IST.

'Vikram' (with rover 'Pragyan' housed inside) is expected to touch down on the surface of the moon on September 7, between 1.30 and 2.30 am.

ISRO Chairman K Sivan has said the proposed soft-landing on the Moon is going to be a "terrifying" moment as it is something the space agency has not done before while the Lunar Orbit Insertion(LOI)manoeuvre was successfully carried out during the previous Chandrayaan-1 mission.

Following the landing, the rover 'Pragyan' will roll out from the lander between 5.30 and 6.30 am on September 7, and carry out experiments on the lunar surface for a period of one lunar day, which is equal to 14 earth days.

The mission life of the lander is also one lunar day, while the orbiter will continue its mission for a year.

Chandrayaan-2 satellite had began its journey towards the moon leaving the earth's orbit in the dark hours on August 14, after a crucial manoeuvre called Trans Lunar Insertion (TLI) that was carried out by ISRO to place the spacecraft on "Lunar Transfer Trajectory." In a major milestone, the spacecraft had successfully entered the lunar orbit on August 20 by performing the LOI operation.

The health of the spacecraft is being continuously monitored from the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from Indian Deep Space Network (IDSN) antennas at Bylalu, near Bengaluru, the space agency has said.

The orbiter carries eight scientific payloads for mapping the lunar surface and studying the exosphere (outer atmosphere) of the Moon while the lander carries three scientific payloads to conduct surface and subsurface science experiments.

The rover carries two payloads to enhance the understanding of the lunar surface.

According to the ISRO, the objective of the mission is to develop and demonstrate the key technologies for end-to-end lunar mission capability, including soft-landing and roving on the lunar surface.

On the science front, this mission aims to further expand knowledge about the moon through a detailed study of its topography, mineralogy, surface chemical composition, thermo-physical characteristics and atmosphere, leading to a better understanding of the origin and evolution of the moon, the space agency had said.

Udupi, Nov 11: A traveller reportedly lost ₹4.1 lakh after attempting to book a cab online in Udupi. 

At around 1:30 PM on November 7, the man from West Bengal searched for car rentals on Google and selected a website named "Shakti Car Rentals." Shortly after, he was contacted by someone claiming to be "Rohit Sharma," who directed him to pay a registration fee of ₹150 on the site.

After unsuccessful payment attempts via both his Canara Bank debit card and SBI credit card (without receiving an OTP), "Rohit Sharma" instructed him to pay the driver directly. But at 1:47 PM, he received messages showing deductions of ₹3.3 lakh from his SBI credit card and ₹80,056 from his Canara Bank debit card, totaling ₹4.1 lakh.

The complainant alleges fraud through a deceptive link disguised as a booking token fee. A case has been registered at Udupi Town Police Station.

The UN special rapporteur for Palestine has slammed Israel’s parliament for passing a law authorizing the detention of Palestinian children, who are “tormented often beyond the breaking point” in Israeli custody.

Francesca Albanese, the UN special rapporteur on the rights situation in the Occupied Palestinian Territory, in a Thursday post on X, characterized the experiences of Palestinian minors in Israeli detention as extreme and often inhumane.

The UN expert highlighted the grave impact of this policy, noting that up to 700 Palestinian minors are taken into custody each year, a practice she described as part of an unlawful occupation that views these children as potential threats.

Albanese said Palestinian minors in Israeli custody are “tormented often beyond the breaking point” and that “generations of Palestinians will carry the scars and trauma from the Israeli mass incarceration system.”

She further criticized the international community for its inaction, suggesting that ongoing diplomatic efforts, which often rely on the idea of resuming negotiations for peace, have contributed to normalizing such human rights violations against Palestinian children and the broader population.

The comments by Albanese came in response to Israel’s parliament (Knesset) passing a law on November 7 that authorizes the detention of Palestinian children under the age of 14 for “terrorism or terrorist activities.”

Under the legislation, a temporary five-year measure, once the individuals turn 14, they will be transferred to adult prison to continue serving their sentences.

Additionally, the law allows for a three-year clause that enables courts to incarcerate minors in adult prisons for up to 10 days if they are considered dangerous. Courts have the authority to extend this duration if necessary, according to the Knesset.

The legislation underscores a shift in the treatment of minors and raises alarms among human rights advocates regarding the legal and ethical ramifications of detaining children and the conditions under which they may be held.

Thousands of Palestinians, including hundreds of children and women, are currently in Israeli jails—around one-third without charge or trial. Also, an unknown number are arbitrarily held following a wave of arrests in the wake of the regime's genocidal war on Gaza.

Since the onset of the Gaza war, the Israeli regime, under the supervision of extremist minister Itamar Ben-Gvir, has turned prisons and detention centers into “death chambers,” the ministry of detainees and ex-detainees’ affairs in Gaza says.

Violence, extreme hunger, humiliation, and other forms of abuse of Palestinian prisoners have been normalized across Israel’s jail system, reports indicate.

Over 270 Palestinian minors are being detained by Israeli authorities, in violation of UN resolutions and international treaties that forbid the incarceration of children, as reported by Palestinian rights organizations.

Mangaluru: A heart-wrenching tragedy unfolded in the quiet Bellayuru village on the outskirts of Mangaluru as a man’s life ended on a railway track following an apparent double murder. Authorities from the Mulki police station identified the man as Karthik Bhat, 32, whose lifeless body was discovered on the tracks with his head positioned on the rail, indicating a tragic suicide.

Nearby, police recovered keys to a scooter and a house, which eventually led them to uncover a series of chilling events. Following the trail, officers located Bhat’s scooter parked near Mahammayi Temple. Inside the vehicle, they found documents confirming his identity, including an RC, insurance papers, and his driving license.

Their search continued to Bhat's home in Pakshikere, Kemral village, where they discovered a locked room. With the keys retrieved from the tracks, police unlocked the door, only to be confronted by a horrifying sight. The bodies of Priyanka (28) and her young son Hriday (4) lay in a pool of blood, pointing to a brutal murder that occurred just hours before Bhat’s suicide.

Initial investigations suggest Bhat, beleaguered by ongoing family disputes, committed the murders of his wife and son on the evening of November 8 before tragically ending his own life. A death note found in his diary hinted at his mental state and tragic intentions.

Priyanka’s family, residing in Shivamogga, was informed of the incident. The couple, married for six years, now leaves behind grieving relatives and unanswered questions. Police have initiated formal proceedings, collecting statements from family members as they continue their investigation into the tragic sequence of events.
