Chandrayaan-2: ISRO to simulate varied scenarios to find why Vikram lander failed

Bengaluru, Sept 14: The Indian space agency will simulate various scenarios, including what it has not done and what it had assumed, to arrive at the probable cause of its moon lander Vikram hitting the lunar surface after veering away from its plotted path and losing communication link with ground stations, a retired senior ISRO official said.

Early on September 7, Vikram, while on its descent to soft land on the Moon's south polar region, apparently lost control and crash-landed there, snapping the communication links.

"The Indian Space Research Organisation (ISRO) has to simulate various things and scenarios with the data on hand. It should also check and simulate what the actions that were not done and the results that they had assumed," the retired official, who preferred to remain anonymous, told IANS.

According to him, ISRO has to see whether any simulation prior to the launch was overlooked or waived any known deviation.

"ISRO should also check out to the extent at which various failure modes were simulated. ISRO has to go into these details. It would take considerable time to arrive at a conclusion," he added.

Space experts had told IANS that normally any data loss from a satellite means it suddenly changed its attitude. The loss of communication link means the target /satellite experienced a large angular rotation.

According to them, the loss of communication link could also be due to wrong input being loaded on to the lander.

In other words, the loss of communication link with Vikram could be due to sudden disturbance - in the form of engine propulsion or wrong data input, experts said.

A former official classified the Chandrayaan-2 mission into four parts: putting the Chandrayaan-2 spacecraft into earth orbit; taking it into the moon orbit; soft landing of the lander Vikram; and rover Pragyan rolling down to carry out scientific experiments.

"Out of the four, the first two were successful and the last two have not happened," he said.

He said ISRO would have got various engineering data from this mission which will be useful for the future course of action.

On July 22, the Rs 978 crore Chandrayaan-2 was launched into the space by India's heavy lift rocket Geosynchronous Satellite Launch Vehicle-Mark III (GSLV Mk III) in a textbook style.

The Chandrayaan-2 spacecraft comprised three segments -- the Orbiter (weighing 2,379 kg, eight payloads), 'Vikram' (1,471 kg, four payloads) and 'Pragyan' (27 kg, two payloads).

After five earth-bound orbit raising activities, Chandrayaan-2 was inserted into the lunar orbit. On September 2, Vikram separated from the orbiter.

Tehran: Iran’s Islamic Revolution Guards Corps (IRGC) has launched “extensive” retaliatory missile and drone strikes against the occupied territories in response to the Israeli regime’s terrorist attack of April 1 against the Islamic Republic’s diplomatic premises in the Syrian capital Damascus.

The Corps announced launching the strikes in a statement on Saturday night, defining the mission as "Operation True Promise."

“In response to the Zionist regime’s numerous crimes, including the attack on the consular section of Iran’s Embassy in Damascus and the martyrdom of a number of our country’s commanders and military advisors in Syria, the IRGC’s Aerospace Division launched tens of missiles and drones against certain targets inside the occupied territories,” the statement read.

Iran's Defense Minister Brigadier General Mohammad Reza Ashtiani, meanwhile, warned that “Whatever country that could open its soil or airspace to Israel for a [potential] attack on Iran, will receive our decisive response.”

The Israeli attack had resulted in the martyrdom of Brigadier General Mohammad Reza Zahedi, a commander of the IRGC's Quds Force, his deputy, General Mohammad Hadi Haji Rahimi, and five of their accompanying officers.

The terrorist attack drew sharp condemnation from senior Iranian political and military leaders, who vowed "definitive revenge."

During a speech in Tehran on Wednesday after leading the Eid al-Fitr prayers, Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei said the Israeli regime “must be punished and will be punished” for the deadly strike on the Iranian diplomatic premises.

The Leader added, “The evil Zionist regime committed another mistake ...  and that was the attack on the Iranian consulate in Syria. The consulate and diplomatic missions in any country are considered to be the territory of that country. When they attack our consulate, it means they have attacked our soil."

In a subsequent statement, the IRGC said the retaliation came after 10 days of "silence and neglect" on the part of the international organizations, especially the United Nations Security Council, to condemn the Israeli aggression or punish the regime in line with Article 7 of the UN Charter.

Iran then resorted to the retaliatory strikes, the Corps added, "using its strategic intelligence capabilities, missiles, and drones" to attack "targets of the Zionist terrorist army in the occupied territories, successfully hitting and destroying them."

The statement, meanwhile, warned the United States -- the Israeli regime's biggest supporter -- that "any support or participation in harming Iran's interests will result in a decisive and regrettable response by the Armed Forces of the Islamic Republic."

"Furthermore, America is held responsible for the evil actions of the Zionist regime, and if this child-killing regime is not restrained in the region, it will bear the consequences," it noted.

The Corps concluded the statement by cautioning third countries against letting their soil or airspace be used for attacks against the Islamic Republic.

New Delhi: Searches conducted by the Enforcement Directorate (ED) under the anti-money laundering law rose by 86 times while arrests and attachment of assets jumped by around 25 times in the ten years since 2014 compared to the preceding nine-year period, according to official data.

An analysis of the data by PTI for the last ten years, between April 2014 and March 2024, against the nine years from July 2005 to March 2014 presents a picture of the federal agency's "intensified" action under various sections of the Prevention of Money Laundering Act (PMLA).

The PMLA was enacted in 2002 and implemented from July 1, 2005, to check serious crimes of tax evasion, generation of black money and money laundering.

While the opposition parties have alleged that the ED's action during the last decade was part of the BJP-led central government's "oppressive" tactics against its rivals and others, the Union government and the ruling party have asserted that the agency is independent and its investigations were purely based on merit and under the mandate to act against the corrupt.

The ED booked as many as 5,155 PMLA cases during the last ten years as compared to a total of 1,797 complaints or Enforcement Case Information Reports (ECIRs or FIRs) filed during the preceding period (2005-14), a jump of about three times, the data said.

The data shows that the agency also got its first conviction starting the 2014 fiscal and it has, till now, got 63 persons punished under the anti-money laundering law.

The ED conducted 7,264 searches or raids in money laundering cases across the country during the 2014-2024 period as compared to just 84 in the preceding period - a jump of 86 times.

It also arrested a total of 755 people during the last decade and attached assets worth Rs 1,21,618 crore as compared to 29 arrests and Rs 5,086.43 crore worth of attachments respectively during the last compared period, the data stated.

The arrests are 26 times more, while figures related to the attachment of properties are 24 times higher.

The agency issued 1,971 provisional attachment orders for various types of immovable and movable assets during the last decade as compared to 311 such orders taken out in the preceding comparable period.

It got about 84 per cent of the attachment orders confirmed from the Adjudicating Authority of the PMLA during 2014-24 as compared to 68 per cent confirmations from the same authority during the last compared period.

The filing of charge sheets also saw a jump of 12 times in the last decade with 1,281 prosecution complaints filed by it before courts as against 102 during the preceding period.

The data said the ED secured conviction orders in 36 cases from various courts leading to the prosecution of 63 persons and a total of 73 charge sheets were disposed of during the last decade.

No conviction was obtained by the agency nor any charge sheet was disposed of under the anti-money laundering law during the 2005-14 period, according to the statistics.

The agency also got the court's permission to confiscate assets (attached as proceeds of crime under the PMLA) worth Rs 15,710.96 crore and it also restituted properties (including bank funds) of Rs 16,404.19 crore (out of the total amount under confiscation) during the last decade.

As there were no convictions during the preceding nine-year period, no confiscation of assets and resultant restitution could take place, as per the data.

The ED is also empowered to seize cash under the PMLA and the data said the agency froze more than Rs 2,310 crore worth of Indian and foreign currency during the last ten years as compared to a figure of Rs 43 lakh during the preceding period.

The agency also got notified a total of 24 Interpol red notices for apprehension of various accused who left India and hid in foreign shores and sent 43 extradition requests during 2014-24.

No such action was taken by the agency during the preceding period.

Four persons were extradited to India during the last ten-year time period while similar orders were secured against businessmen Vijay Mallya, Nirav Modi and Sanjay Bhandari. The three are based in the UK and the ED is trying to bring them back to the country as all the accused are contesting the orders issued against them.

"These statistics reflect the intensive drive that the ED has undertaken to check money laundering crimes," an agency official said.

The ED investigates financial crimes under two criminal laws -- the Prevention of Money Laundering Act (PMLA) and the Fugitive Economic Offenders Act (FEOA) -- apart from the civil provisions of the Foreign Exchange Management Act (FEMA).

The FEOA was enacted by the Narendra Modi government in 2018 to cripple those who are charged with high-value economic frauds and abscond from the country to evade the law.

The ED, as per the data, filed a total of 19 such applications before the designated special PMLA courts in the country following which 12 persons have been declared fugitive economic offenders.

It also confiscated assets worth Rs 906 crore under the said law by the end of the last fiscal on March 31.

Mangaluru: After as the state health ministry issued guidelines to the public in view of a heatwave, the health department in Dakshina Kannada has advised people to be cautious about the impact of heatstroke, including heat rash, heat edema, heat cramps, heat tetany, heat syncope, and heat exhaustion.

Dakshina Kannada district nodal officer for climate change, Dr Naveenchandra Kulal, said that the impact of heat-related illness can also be found in the district, when there is a variation of about 4.5⁰C from the normal temperature.

Dr Kulal told media persons here on Friday, that the impact of heat-related illness is not confined to Raichur, Kalaburagi, and other North Karnataka districts.

“Those who reside inside tin sheet houses and closed environments are likely to suffer from heatstroke. People should hydrate themselves by drinking more water and avoid working under the direct Sun. Heat exhaust fans can be used. Though no heatstroke cases have been reported in the district, any negligence may cause heatstroke,” he said. 

DHO Dr Thimmaiah HR said that hotels and restaurants should supply boiled water, and they should clean the overhead tanks once every three months. The filter of drinking water units should be cleaned frequently, he said.

He also directed paying guest accommodations to supply fresh food to inmates.

“We have received complaints of many paying guest accommodations serving sambar cooked the previous day to inmates. Stale food should be avoided, as there are chances of food contamination. Plastics should be avoided while packing food in hotels. As per the Food Safety and Standards Authority of India (FSSAI) guidelines, the use of plastic to pack hot food is restricted,” the DHO said.
