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.

Hamas says the Israeli regime’s bombing of the Gaza Strip, which is enduring a genocidal Israeli war, has killed 70 percent of the Zionist captives, who have been held by the Palestinian resistance movement since an October operation.

Khalil al-Hayya, deputy chief of Hamas’ Political Bureau, announced the information in an interview with Lebanon’s al-Manar television network on Thursday.

“The Zionist enemy wants to recover the remaining captives by force, killing them by bombing,” he said.

Around 250 people were taken captive on October 7 last year during Al-Aqsa Storm, a retaliatory operation by Gaza’s resistance groups.

At least 35,272 Palestinians have died in an Israeli war of genocide that began following the operation.

Hamas released 105 of the captives during a week-long truce in late November.

Hamas recently agreed to another truce proposal enabling cessation of the Israeli aggression and release of the rest of the captives. The Israeli regime, however, rejected the proposal.

The Hamas’ official said, “The latest proposal presented to us comes very close to our demands, but the enemy has not respected the proposal or the mediators.”

Al-Hayya reiterated the movement’s demands, saying any potential truce agreement had to mandate a complete and comprehensive cessation of the Israeli aggression, withdrawal of all Israeli forces from Gaza, and then a captive exchange deal.

‘Victory is our ally’

The Hamas’ official pointed to the Israeli regime’s failure to realize its war goals, including defeating the resistance.

“After eight months of aggression, the enemy has failed to eradicate the resistance in Gaza despite all the actions of the occupation,” he said.

“The resistance has rebuilt itself and can adapt its capabilities to face the occupation,” the official said, asserting, “The resistance is capable of enduring for many months and will continue to defend its people as long as the battle is ongoing.”

“The resistance has the ability to continue because it is right, and victory is our ally, while the enemy will face defeat.”

Thanking regional resistance

Elsewhere in his remarks, al-Hayya expressed gratitude towards the regional resistance groups for the pro-Palestinian operations that they have been carrying out against Israeli targets and those associated with the occupying regime.

“The fronts in Yemen, Lebanon, and Iraq support Gaza and link the cessation of [their] operations to the end of aggression on Gaza,” he said.

“When we meet with the resistance forces in the region, we affirm that the battle is one.”

Jerusalem: Israel and India will continue to deepen their bilateral ties and lead to greater prosperity, Foreign Minister Israel Katz said on Tuesday.

Katz was responding to India’s External Affairs Minister S Jaishankar’s message on the occasion of Israel’s 76th Independence Day.

“Thank you for the warm wishes, FM @DrSJaishankar. In celebration of our Independence Day, Israel and India will continue to deepen our ties and lead to greater prosperity,” Katz said in a post on X.

Earlier in the morning, Jaishankar posted on X a 2:03-minute video showcasing the India-Israel relationship through photos of various bilateral meetings between Prime Minister Narendra Modi, himself, and other Indian ministers with Israel Prime Minister Benjamin Netanyahu and other ministers.

“Congratulate FM @Israel_katz and the people of Israel on the occasion of the 76th anniversary of Israel’s Independence. Mazel Tov!,” Jaishankar posted along with the video and repeated the same message in another post in Hebrew.

Meanwhile, President Droupadi Murmu wished her Israeli counterpart Isaac Herzog as she said on X, “I join the people of India in conveying our best wishes to President @Isaac_Herzog, and the people of Israel on the 76th anniversary of Israel’s independence.”

Lok Sabha speaker Om Birla too took to X to post his greetings to his counterpart Amir Ohana, the Speaker of The Knesset: “On the occasion of Israel’s 76th anniversary of independence, I congratulate Speaker of the Knesset @AmirOhana and the people of Israel.”

Both Murmu and Birla also included greetings in Hebrew.

“Thank you, my dear friend @ombirlakota. May the friendship between our nations grow stronger,” Ohana replied to Birla and also added a line in Devnagari script in Hindi, loosely translated as, “Thank you my dear friend Om Birla. May the friendship between our countries be stronger.”

In an intriguing turn of events, authorities have levied a fine against an actress for breaching traffic regulations depicted within a television serial.

In the 14th episode of the popular serial ‘Seetha Raama’ a Kannada language drama series airing on Zee Kannada, a scene featuring two individuals riding a scooter caught the attention of viewers. While the rider adhered to safety protocols by wearing a helmet, the actress on the pillion did not.

Jayaprakash Yekkur, a vigilant resident of Mangaluru, took swift notice of this discrepancy and promptly lodged a complaint with the Mangaluru City Police Commissioner. Yekkur underscored the concern that such portrayals of traffic violations by actors and actresses could potentially convey misleading messages to viewers, particularly those who are impressionable. He urged authorities to take decisive legal action against the actress, the serial’s director, and the broadcasting channel.

In response to Yekkur’s complaint, the Commissioner of Police forwarded the matter to the Mangaluru Traffic Police station. Subsequently, notices were issued to the owner of the two-wheeler featured in the scene and the serial’s director. Upon investigation, it was revealed that the scene had been filmed in Nandini Layout, Bengaluru, and was referred to the Rajajinagar police station for further scrutiny.

On May 10, after thorough inquiries, the Rajajinagar police station imposed a fine of Rs 500 on both the actress and the owner of the two-wheeler. Furthermore, the production manager of the serial committed to adhering strictly to traffic regulations in future episodes.

Expressing his contentment with the resolution, Jayaprakash Yekkur commented that the prompt response from the police, coupled with the imposition of a fine, serves as a valuable lesson and contributes significantly to enhancing public awareness.
