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: Voting was underway on Friday in the first phase of Lok Sabha polls in 14 constituencies in Karnataka. Polling began at 7 am and will end at 6 pm.

A total of 247 candidates -- 226 men and 21 women -- are in the fray for the first phase covering most of the southern and coastal districts, where more than 2.88 crore voters are eligible to exercise their franchise in 30,602 polling stations.

The Congress and BJP are locking horns on the electoral battleground again in less than a year. This election is witnessing a straight fight between the ruling Congress and the BJP-JD(S) combine unlike the Assembly elections in May last year which witnessed a triangular contest among the three parties.

The state has a total of 28 Lok Sabha constituencies. The second phase of polling in the remaining 14 seats is on May 7.

In the first phase, while the Congress is contesting in all 14 seats, BJP has fielded nominees in 11 and its alliance partner JD(S), which joined the National Democratic Alliance in (NDA) in September last year, in three -- Hassan, Mandya and Kolar.

Besides the three, the segments where elections are being held on Friday are: Udupi-Chikmagalur, Dakshina Kannada, Chitradurga, Tumkur, Mysore, Chamarajanagar, Bangalore Rural, Bangalore North, Bangalore Central, Bangalore South and Chikkballapur.

According to Election Commission, 1.4 lakh polling officials are on duty for the first phase. Besides them, 5,000 micro-observers, 50,000 civil police personnel, and 65 companies of Central Paramilitary Force and State Armed Police force of other States have been deployed for security. All the 2,829 polling stations of Bangalore Rural parliamentary constituency are being webcast.

"This is as per the request of our returning officers and observers; so we have given more than double the Central paramilitary force for Bangalore Rural constituency. Seven companies of Central paramilitary forces have been inducted at the constituency since April 22," Karnataka Chief Electoral Officer Manoj Kumar Meena has said.

In fact, out of the total 30,602 polling stations in the first phase, 19,701 are webcast, and 1,370 covered via CCTVs, he had added. Chikkaballapur has a maximum number of 29 candidates, followed by 24 in Bangalore Central, and Dakshina Kannada has the least number at nine.

JD(S) leader H D Kumaraswamy from Mandya, his brother-in-law and noted cardiologist C N Manjunath from Bangalore Rural on a BJP ticket against Deputy CM D K Shivakumar's brother and MP D K Suresh of Congress, and erstwhile Mysuru royal family scion Yaduveer Krishnadatta Chamaraja Wadiyar from Mysore, from the BJP, are among the prominent candidates in the fray in the first phase.

Also in the contest are BJP MP Tejasvi Surya from Bangalore South pitted against Minister Ramalinga Reddy's daughter Sowmya Reddy of Congress, and Union Minister Shobha Karandlaje on BJP ticket from Bangalore North against former Indian Institute of Management Bangalore professor M V Rajeev Gowda of Congress.

Austrian police authorities have arrested the director of a Palestinian news agency based in the Gaza Strip, which is aligned with the Hamas resistance movement, following spurious allegations and intense pressure from the Tel Aviv regime’s officials.

Gaza Now News Network wrote in a post published on the social media platform X, formerly known as Twitter, that “the occupying Israeli regime is trying hard to prosecute anyone connected to the Palestinian media as part of attempts to silence the voice of wounded Gaza and stop disclosure of the Palestinian nation’s sufferings and the massacres being committed against women, children and the elderly.”

It added, “The latest of such attempts was the prosecution of Palestinian-born journalist Mustafa Ayyash. Austrian police stormed his house, tampered with his personal belongings, confiscated electronic devices, arrested him and his wife, and took him for interrogation.”

Gaza Now noted that the Austrian police hacked its WhatsApp account, which is followed by 300,000 users, and closed it down. They also shut the news network’s Facebook pages and accounts, which are followed by some eight million users.

It underscored that Israeli officials threaten Ayyash from time to time with prosecution and assassination, and hamper the activities of the news network on social media platforms.

This comes as the Israeli military had earlier targeted Ayyash's family and killed scores of his relatives in a series of airstrikes in late November ahead of a temporary ceasefire.

The Permanent Observer of Palestine at the United Nations Salah Abdel-Shafi and Chairman of Hamas Political Bureau Ismail Haniyeh mourned the death of his family.

Back on March 27, US and UK authorities unveiled sanctions against two people and three companies related to Gaza Now over alleged fundraising efforts “in support of Hamas.”

The Treasury Department said in a statement that Gaza Now, whose popular Telegram channel has more than 1.8 million followers, and its founder started fundraising for Hamas after the movement’s Operation al-Aqsa Storm against Israel on October 7.

The US also slapped sanctions against Aozma Sultana, the director of two companies that allegedly gave “thousands of dollars to Gaza Now and advertised Gaza Now as a partner during a joint fundraiser shortly after the large-scale surprise attack.”

Separately, the UK Treasury announced a full asset freeze against two individuals suspected of providing financial support for Gaza Now.

“All funds and economic resources in the UK belonging to or controlled by Sultana and Ayyash have been frozen,” they added.

Union Finance Minister Nirmala Sitharaman, on Friday, said that the Bharatiya Janata Party (BJP) plans to reintroduce electoral bonds in some capacity following extensive consultations with all stakeholders, should it come back to power in the 2024 general elections, according to a report in the Hindustan Times (HT).

HT cited Nirmala Sitharam as saying, “We still have to do a lot of consultation with stakeholders and see what is it that we have to do to make or bring in a framework which will be acceptable to all, primarily retain the level of transparency and completely remove the possibility of black money entering into this.”

However, the Centre has not yet decided whether to seek a review of the ruling made by the Supreme Court (SC), she said.

She further added, “What the scheme, which has been just thrown out by the Supreme Court, brought in was transparency. What prevailed earlier was just free-for-all.”

Launched in 2018, electoral bonds were accessible for acquisition at any State Bank of India (SBI) branch. Contributions made through this programme by corporations and even foreign entities via Indian subsidiaries received full tax exemption, while the identities of the donors remained confidential, safeguarded by both the bank and the recipient political parties.

On February 15, a five-judge Constitution Bench struck down the scheme, deeming it ‘unconstitutional’ due to its complete anonymisation of contributions to political parties. Additionally, the Bench stated that the articulated objectives of curbing black money or illegal election financing did not warrant disproportionately infringing upon voters’ right to information.

FM Sitharaman said, some aspects of the scheme need improvement and they will be brought back following consultations.

She also lashed out at the Opposition’s claims that the BJP disregarded criminal charges against leaders who switched from other parties to join the ruling party.

The HT quoted her as saying, “The BJP can’t sit here and say, you come to my party today, and the case will be closed tomorrow. The case has to go through the courts that have to take a call; they will not just say, “Oh, he’s come to your party, close the case.” Doesn’t happen that way. So is this washing machine a term they want to use for the courts?”

She further said that the Union government plans to simplify the process of taxation and make it easy for investments to come through into the country.
