Chennai, Nov 26: Indian Space Research Organisation’s (ISRO) PSLV-C54 carrying an earth observation satellite and eight nano-satellites lifted off from the first launch pad of the Satish Dhawan Space Centre (SDSC) in Sriharikota near here. 

The PSLV-C54 took off at 11.56 am on Saturday at the end of a 25.30-hour countdown which began at 10.26 am on Friday. This is the 56th flight of the Polar Satellite Launch Vehicle of ISRO and 24th flight of the extended PSLV-XL version. 

While the primary satellite (EOS-06) will be separated in Orbit-1, two Orbit Change Thrusters (OCTs) introduced in the propulsion bay ring of the rocket will subsequently change the orbit. The passenger payloads (PPLs) will be placed in different orbits in Orbit-2.

The customer payloads are ISRO Nano Satellite-2 for Bhutan (INS-2B), Anand, four satellites of Astrocast, and two satellites of Thybolt. Scientists said the mission will be one of the longest undertaken by the ISRO as they have to engage the rocket to change orbits.

EOS-06, which is the third generation satellite in the Oceansat series, is aimed at providing continuity in services of Oceansat-2 spacecraft with enhanced payload specifications as well as application areas. 

Scientists said the other objectives of the primary satellite is to ensure the data continuity of Ocean colour and wind vector data to sustain the operational applications, and to develop and improve related algorithms and data products to serve in well- established application areas and to enhance the mission utility.

The satellite will also improve applications, some additional datasets such as sea surface temperature and more number of bands in optical region for florescence and in infrared region for atmospheric corrections are accommodated.

ISRO nano satellite-2 spacecraft is configured with INS-2 bus which will have two payloads -- NanoMx and APRS-Digipeater. While NanoMx is a multispectral optical imaging payload developed by Space Applications Centre (SAC), APRS-Digipeater payload is jointly developed by DITT- Bhutan and URSC.

The Anand Nano satellite will to demonstrate the capabilities and commercial applications of miniaturized earth-observation camera for earth observation using a microsatellite in Low Earth Orbit.

Astrocast, a 3U spacecraft is a technology demonstrator satellite for the Internet of Things (IoT) as the payload. There are 4 nos. of Astrocast Satellites in this mission. These spacecraft are housed within an ISISpace QuadPack dispenser, while Thybolt is a 0.5U spacecraft bus that includes a communication payload to enable rapid technology demonstration and constellation development for multiple users.

The number of Palestinians arrested by Israeli military forces in the occupied West Bank has surged to 8,165 since October 7, when Israel launched its relentless offensive against Palestinians in the Gaza Strip.

The Palestinian Prisoners Society and the Commission of Detainees and ex-Detainees in a joint statement on Tuesday said that over the past 24 hours, Israeli forces had arrested 20 Palestinians across the West bank.

The statement said that most of the arrests took place in Tulkarm, with additional arrests scattered across other cities, towns and refugee camps in the West Bank such as Beit Lahm, al-Khalil, Ramallah, Nablus, Tubas, and al-Quds.

The arrests were made amidst reports of widespread abuse, severe beatings, threats against detainees and their families, and extensive vandalism in citizens' homes and prisoners' residences in the Israeli prisons.

In the aftermath of the al-Aqsa Storm, over 8,165 arrests were made in the West Bank, with individuals including children being detained from their homes, at military checkpoints, coerced into surrendering, and even taken hostage, the statement revealed.

These figures do not include the thousands of adults and children the Israeli army has detained, tortured and interrogated in makeshift prisons across Gaza, outside any legal or civilian oversight.

Conditions for Palestinian prisoners in Israeli jails have allegedly worsened considerably, with detainees experiencing extreme overcrowding and limited access to essential rights, including food, water, electricity, medical care, family visits, and legal assistance.

Palestinian prisoner groups have repeatedly reported that Palestinians in Israeli prisons are being denied medical care, which pushes those jailed to the brink of death.

At least 10 Palestinians have died in Israeli prisons since Israel’s war on Gaza began, according to Palestinian news agency WAFA. But an investigation by Israeli daily Haaretz revealed that the number was actually at least 27. Rights groups put the number even higher.

Israel has intensified its attacks against Palestinians throughout the West Bank since October 7, when it launched a devastating war on the besieged Gaza Strip.

Since then, the Israeli forces and settlers have killed at least 459 Palestinians from the West Bank, with over 4,750 others sustaining injuries.

In the span of the past six months, at least 33,482 Palestinians, mostly women and children, have been killed in Gaza. The relentless violence has also resulted in the mass displacement of the 2.3 million people inhabitants of the Gaza Strip.

Concerns have been raised regarding the fate of those who have gone missing, as they may be trapped beneath the rubble or confined within makeshift Israeli prisons.

The significant number of Palestinian detainees remaining in Israeli prisons is a crucial role in truce negotiations between Palestinian resistance group Hamas and Israel.

About 130 of the 250 Israeli captives taken during Operation Al-Aqsa Storm are still in Gaza after a provisional truce deal in December saw the exchange of a number of prisoners between the two sides.

New Delhi:  Twenty-nine Maoists, including a senior rebel leader - Shankar Rao, who had a bounty of ₹ 25 lakh on his head - were killed by security forces during an encounter in Chhattisgarh's Kanker district on Tuesday afternoon. A huge quantity of weapons, including Ak-47 and INSAS rifles, were recovered. 

Three security personnel were injured in the gunfight, which took place in forests near the village of Binagunda after a joint team of District Reserve Guard and Border Security Force were attacked.

Two of the three injured are from the BSF. Their condition is stable but the third - from the DRG - is in critical care. All three received treatment at a local hospital and are to be shifted to a larger facility.

Sources said the fighting began at around 2 PM, when a joint DRG-BSF team was conducting an anti-Maoist operation. The DRG was set up in in 2008 to combat Maoist activities in the state, and the Border Security Force has been deployed extensively in the area to for counter-insurgency ops.

There was another encounter in the district last month, in which two people - a Maoist and a cop - were killed, and security forces recovered a gun, some explosives, and other incriminating materials.

Personnel from the DRG and Bastar Fighters, both units of the state police force, with the Border Security Force, were involved in that operation, officials told news agency PTI. The patrolling team was cordoning off a forested area when fired on indiscriminately, leading to the gun battle.

In November last year, while the state was voting in the first phase of an Assembly election, a gunfight broke out between security forces and Maoist rebels in the same district.

An Ak-47 rifle was recovered from the encounter site.

On the same day, while polling was taking place, Maoists fired at DRG personnel deployed near a polling station in Banda in Dantewada district.

New Delhi: India is likely to experience above-normal cumulative rainfall in the 2024 monsoon season with La Nina conditions likely to set in by August-September, the IMD has said on Monday.

However, normal cumulative rainfall does not guarantee uniform temporal and spatial distribution of rain across the country, with climate change further increasing the variability of the rain-bearing system.

Climate scientists say the number of rainy days is declining while heavy rain events (more rain over a short period) are increasing, leading to frequent droughts and floods.

Based on data between 1951-2023, India experienced above-normal rainfall in the monsoon season on nine occasions when La Nina followed an El Nino event, India Meteorological Department chief Mrutyunjay Mohapatra told a press conference here.

Positive Indian Ocean Dipole conditions are predicted during the monsoon season. Also, the snow cover in the Northern Hemisphere is low. These conditions are favourable for the Indian southwest monsoon, he said.

Moderate El Nino conditions are prevailing at present. It is predicted to turn neutral by the time monsoon season commences. Thereafter, models suggest, La Lina conditions may set in by August-September, Mohapatra said.

India received "below-average" cumulative rainfall -- 820 mm compared to the long-period average of 868.6 mm -- in 2023, an El Nino year. Before 2023, India recorded "normal" and "above-normal" rainfall in the monsoon season for four years in a row.

El Nino conditions -- periodic warming of surface waters in the central Pacific Ocean -- are associated with weaker monsoon winds and drier conditions in India.

Three large-scale climatic phenomena are considered for forecasting monsoon season rainfall.

The first is El Nino, the second is the Indian Ocean Dipole (IOD), which occurs due to differential warming of the western and eastern sides of the equatorial Indian Ocean, and the third is the snow cover over the northern Himalayas and the Eurasian landmass, which also has an impact on the Indian monsoon through the differential heating of the landmass.

The southwest monsoon delivers about 70 percent of India's annual rainfall, which is critical for the agriculture sector. Agriculture accounts for about 14 percent of the country's GDP.
