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

Agencies
September 3, 2019

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.

Bengaluru: The Prime Minister Narendra Modi led union government has requested the Karnataka High Court to direct the Mandya district administration and the state government to clear a madrasa operating within the premises of the historic Jama Masjid in Srirangapatna.

The Waqf Board, opposing this move, has claimed the mosque as its property and defended the right to conduct madrasa activities there.

The matter was brought before a division bench headed by Chief Justice N V Anjaria following a public interest litigation filed by a person named Abhishek Gowda from Kabbalu village in Kanakapura taluk. The petition alleged “unauthorised madrasa activities” within the mosque.

Representing the Central government, Additional Solicitor General of India for High Court of Karnataka, K Arvind Kamath argued that the Jama Masjid was designated as a protected monument in 1951, yet unauthorised madrasa operations continue there.

He noted that concerns over potential law and order issues have so far prevented any intervention. Kamath urged the court to direct the Mandya district administration to take action and vacate the madrasa from the mosque.

In defence, lawyers for the state government and the Waqf Board contested this request, stating that the Waqf Board had been recognised as the owner of the property since 1963 and, thus, conducting madrasa activities there is lawful.

After hearing both sides, the bench adjourned the case for further arguments, scheduling the next hearing for November 20.

In the wake of the tragic drowning of three students at a resort near Ullal on the outskirts of Mangaluru city, the tourism department in Dakshina Kannada is set to implement comprehensive safety guidelines for properties with swimming pools or beach access. This initiative aims to ensure guest safety and prevent similar incidents in the future.

New Safety Mandates for Resorts and Homestays

Rashmi S.R., deputy director (in-charge) of the tourism department, announced, “We will instruct all homestays and resorts to enforce precautionary measures, especially those with pools or direct beach access. Properties must ensure 24/7 supervision, particularly during guest hours. This tragedy highlights the importance of having trained personnel on-site.”

Key Safety Guidelines

The district, home to around 150 homestays and 130 resorts, will see the following measures enforced:

  • Clearly displaying pool depths.
  • Installing adequate safety equipment, such as life buoys.
  • Employing trained lifeguards at all times.
  • Establishing clear pool operating hours.
  • Reviewing and implementing standard operating procedures (SOPs) for pool and beach usage.

Booming Beach Tourism Calls for Vigilance

Manohar Shetty, president of the Association for Coastal Tourism (ACT), Udupi, highlighted the growing popularity of beachside resorts, particularly during peak seasons. Properties in Udupi, often fully booked with tourists from Bengaluru, Mysuru, Kodagu, and Shivamogga, face increasing pressure to maintain safety standards.

Udupi district boasts 22 beachside commercial properties catering to this rising demand.

Shetty emphasized, “Authorities must scrutinize safety measures and carefully evaluate guidelines before issuing new resort licenses. Panchayats should rely on the Karnataka Town and Country Planning Act when handling such cases.”

Long-Term Solutions for Water Safety

Recognizing the need for a cultural shift in water safety, Shetty proposed integrating swimming lessons into school curricula. This move would not only equip students with essential skills but also encourage safe participation in water-based activities.

A Safer Tomorrow for Coastal Tourism

As the tourism sector thrives, Mangaluru’s proactive approach underscores its commitment to visitor safety. The tragic incident serves as a wake-up call, propelling the industry towards stricter regulations and better preparedness, ensuring that coastal vacations remain both enjoyable and safe.

Beirut: The Israeli army on Tuesday continued to launch attacks against civilians in Lebanon, targeting them in several areas without prior evacuation warnings.

However, 13 airstrikes on Beirut’s southern suburbs in the space of only three hours were preceded by evacuation warnings.

The attacks caused no injuries but resulted in widespread destruction of residential buildings and commercial, medical and educational centers.

The airstrikes in southern Lebanon and Bekaa region, reaching Akkar in Lebanon’s far north, erased any hope of a near-term ceasefire settlement.

The strikes were accompanied by an announcement on Israel’s Channel 14 that “the Israeli army has expanded its operations in southern Lebanon to areas it had not reached since the beginning of the ground operation.”

About 50 days have passed since Israel intensified its hostile operations in Lebanon targeting Hezbollah. The death toll from these confrontations and attacks has passed 3,200, with more than 14,000 wounded.

For the first time, an airstrike targeted a mountainous area between Baalchmay and Aabadiyeh on the road leading to Aley, destroying a building housing displaced people.

The mayor of Baalchmay, Adham Al-Danaf, confirmed that “the airstrike targeted a residential building in the Dhour Aabadiyeh area.”

The initial toll from the Ministry of Health showed “five people killed and two injured.”

The raids that targeted Beirut’s southern suburbs for the first time in the morning, unlike nightly raids before, caused huge destruction. Those who evacuated their homes after Israeli warnings, used their phones to record the collapse of empty buildings in Sfeir, Haret Hreik, Bir Al-Abed, Mrayjeh, Laylaki and Hadath.

Israeli warplanes also targeted Tyre, where a strike on a building killed three people and injured many others, while a raid on Tefahta killed a man identified as Kifah Khalil and his family.

Attacks were widespread, with Yater and Zebqine subject to artillery shelling, a civilian being killed in Hermel, and further attacks on Bouday and an area between the towns of Srifa and Arsoun.

A raid on the town of Siddiqin killed two people and injured several others, while an attack on the Mechref farm led to one fatality and multiple injuries.

The search for those missing after an Israeli raid on the town of Ain Yaacoub in Akkar, in the northernmost part of Lebanon, continued until dawn.

During the operation, 14 bodies were retrieved, identified as those of residents displaced from the town of Arabsalim in the Iqlim Al-Tuffah area of the south, along with members of a Syrian family, a mother and three of her children. Additionally, there were 10 people in critical condition.

The targeted residence belongs to a Lebanese citizen, Hussein Hashim, who is reported to be a member of the Syrian Social Nationalist Party.

An airstrike on the town of Saksakiyeh in the Sidon region on Monday night resulted in yet another tragedy.

It appeared that the intended target was the Shoumer family, who just days before lost Hussein Amin Shoumer and his two sisters in a drone strike near Al-Awali River.

Israeli army spokesperson Avichay Adraee issued additional evacuation warnings for towns in the southern region along the Litani River, which, according to estimates from the mayors, are currently 90 percent uninhabited.

In the meantime, Hezbollah announced its continued efforts to “combat the intrusions of Israeli forces and to strike military installations and towns in the north.”

Hezbollah said in a statement that it confronted “an Israeli Hermes 450 drone in the airspace of Nabatieh and forced it to leave Lebanese airspace.”

The party also announced that it targeted “Kfar Blum settlement with a rocket salvo.”

On the Israeli side, air raid sirens sounded in areas of Upper and Western Galilee and in the town of Kiryat Shmona and its surroundings.

The Israeli army confirmed that “a drone exploded in Nesher, east of Haifa, without activating the air raid sirens,” and that “a drone launched from Lebanon crashed into a school in Gesher HaZiv, north of Nahariya.”

Israel’s Channel 13 reported the Israeli military’s assessment regarding Hezbollah’s military strength, claiming that the group currently possesses approximately 100 precision missiles, thousands of artillery shells, and hundreds of rockets. Additionally, it was highlighted that “there are around 200 Lebanese towns that remain unvisited.”
