Reducing the orbit of Chandrayaan-2 Orbiter to pick up any weak signals or to take a closer look the moon lander Vikram that had crash-landed on the lunar surface is a dangerous move, contend space scientists.

According to sources, the Indian Space Research Organisation (ISRO) is looking at reducing Chandrayaan-2 Orbiter’s orbit from 100 km to 50 km above the lunar surface.

“Reducing the orbit of the Orbiter is a dangerous idea,” a former space agency official, speaking on condition of anonymity, told IANS.

“What is ISRO going to gain by this move is not known. Even if the Orbiter is able to pick up weak signals, in all probability, it will not be able to revive Vikram.

“At or above 100 km altitude, the Orbiter is safe. But if it is brought down to 50 km, then it has to be maintained there which requires firing of the on-board engines. If that is not done, the Orbiter will slowly go down,” he added.

Firing of Orbiter’s on-board engines will expend fuel and thereby reducing its life, he said.

“To bring down the Orbiter, ISRO has to fire its motors. Then to maintain that at 50 km height, fuel has to be expended. If ISRO decides to take it up to 100 km altitude, then further fuel has to be expended,” the expert remarked.

According to him, what is on hand is the precious Orbiter which should not be risked at this stage.

“The lander Vikram has gone. Period,” he added.

On September 8, the Indian Space Research Organisation (ISRO) said it has found Vikram on the lunar surface.

“The lander seems to have hit the lunar surface and is in an upturned position,” an official told IANS preferring anonymity.

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 text book 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.

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.

Meanwhile, ISRO officials said that any update on Chandrayaan-2 mission, including the status of the moon lander Vikram that crash landed on the lunar surface on Saturday, will be announced on the organisation’s website. (IANS)

From India’s Chandrayaan 2 mission to the first all-women spacewalk and commercial crew milestones by US-based companies, 2019 offered several exciting moments for space enthusiasts.

India’s ambitious and keenly watched lunar mission, Chandrayaan 2, was expected to make its soft landing on the surface of the Moon on September 7. While the whole nation waited with bated breath, Chandrayaan 2’s lander ‘Vikram’ lost communication with the ground stations. But the Orbiter component of Chandrayaan 2 spacecraft made it to the Moon without any glitch.

In a huge milestone for China, which is attempting to position itself as a leading space power, the country’s Chang’e-4 lunar probe on January 3 became the first spacecraft to make a soft landing on the far side of the Moon. The probe, comprising a lander and a rover, touched down at the pre-selected landing area at 177.6 degrees east longitude and 45.5 degrees south latitude on the far side of the Moon. The programme Chang’e (named in honour of a goddess who, according to Chinese legend, lives on the Moon) intends to send a manned mission to the Moon in the long term and although no deadline has been set, some experts indicated it may be around 2036.

India also conducted its first anti-satellite missile test – Mission Shakti – in 2019. Prime Minister Narendra Modi on March 27 announced that the country’s anti-satellite missile successfully targeted a live satellite on a low earth orbit in just three minutes. India is only the fourth country in the world to achieve this feat after the US, Russia and China.

In October, astronauts Jessica Meir and Christa Koch made history with the first all-female spacewalk, an excursion to repair a power unit on the International Space Station. The women spent seven hours and 17 minutes working outside the ISS as it circled the Earth at 27,600 km/h (17,100 mph), Efe news reported. Koch and Meir paused in their work for a few minutes to take a call from US President Donald Trump.

In a big leap for NASA’s Commercial Crew Programme, SpaceX and Boeing conducted the uncrewed flight test of their spacecraft to the International Space Station. The Elon Musk-owned SpaceX’s Crew Dragon capsule completed its historic unmanned flight test in March with a splashdown in the Atlantic Ocean right on time. Boeing’s passenger spacecraft was launched on its first unmanned flight test to the ISS atop a United Launch Alliance (ULA) Atlas V rocket in December, but the Boeing Starliner spacecraft did not reach the planned orbit. Although Starliner did not reach its planned orbit and dock at the International Space Station as planned, Boeing was able to complete a number of test objectives during the flight related to NASA’s Commercial Crew Programme. The landing of the spacecraft in White Sands, New Mexico, was successful. (IANS)
