NCERT Reading Modules Credit Modi for Success of Chandrayaan-3, Mix Space Science with Vedas
Space science experts say the special supplementary reading modules by NCERT on the Chandrayaan mission do injustice to ISRO and its scientists, who have over the years bounced back from every failure in their way.
China's top lunar scientist poo pooing #India's attempt at landing closer to the South pole than others, and the power of their humbler rocket pretty much sums up #China as a country: an insecure bully. #Chandrayaan3
Day Has Returned, but India's Lander and Rover have Failed to Wake Up
After the successful landing on the Moon, ISRO's Vikram lander and Pragyaan rover had to work quickly while the Sun shone. Once the Sun set after 14 days, it was expected temperatures would drop so low that the solar-powered spacecraft would no longer be able to keep themselves warm enough. Mission controllers received the final data at the end of August and then waited for the end of the 14-day lunar night. Day has returned, but the explorers have received no messages, so it's assumed they didn't survive the night.
‘No salaries in last 18 months’: Workers who made parts for ISRO satellite launches stage protest
Employees of the government-owned Heavy Engineering Corporation say they have been struggling to make ends meet. On September 17, BBC Hindi had reported that some employees of the Heavy Engineering Corporation who contributed in building a launchpad for the Indian Space Research Organisation had taken up odd jobs, including selling idlis, tea and momos, by the roadside in Ranchi.
🌑 #Chandrayaan3 : pour le moment l'ISRO n'a pas réussi à établir de communications avec l'atterrisseur #Vikram et le rover #Pragyan au début de la sortie de la nuit lunaire, même si l'espoir est mince d'une continuité de la mission
All eyes are now on the moon again as the sun rises over India's Chandrayaan-3 lander and rover. The solar panels should be receiving sufficient solar energy by tomorrow. What remains to be seen is whether Chandrayaan-3 and its electronic systems survived the below --150°C lunar temps over the 2-week lunar night. Hopefully, some subsystems, if not all, did.
Sun elevation should be around 5° at this time (Sep 21 00:00 UTC) and increase to 9° in the next 24 hours.
Note that since the moon does not have an atmosphere, the low elevation angle of the sun does not much affect the intensity of solar radiation at the Chandrayaan-3 site. The solar panels are oriented almost vertically and should be generating power and charging the batteries, as the rest of the spacecraft warms up.
Also, Chandrayaan-3 was not designed to survive the lunar night; it does not have an energy source for nighttime heating like other long-duration missions.
If the event is confirmed to be a moonquake, it would be the first detected on the lunar surface since the 1970s — when #NASA's #Apollo missions first studied seismic activity on the moon and detected #moonquakes.
A #moonquake would suggest that the moon isn't just some big, dense space rock — there's actually more going on under its surface than meets the eye. #Chandrayaan3#Vikram
As Night Falls, India's Lunar Lander/Rover Goes to Sleep. Probably Forever
After two weeks of daylight, night has finally returned to the Chandrayaan-3 landing site, shutting off its energy source and dropping the temperature precipitously. India's space agency announced that they have transferred all their data home and switched off the lander and rover, putting them into safe mode. The lander and rover were only designed to last a single lunar day, but ISRO hopes they'll somehow last through the two weeks of lunar night and wake up again - but it's a longshot.
How Scientists Meghnad Saha, J.V. Narlikar Rubbished Claim of Vedic Roots of Modern Science
“If superior knowledge in astronomy, aeronautical engineering, etc., is available in the ancient texts in Sanskrit, why isn’t the ISRO using them? Can (S. Somanath) show one piece of technology or theory that ISRO has taken from the Vedas and applied to make a rocket or a satellite?”
The #Chandrayaan3 mission surprised yet again, when the #Vikram lander did a short hop on the lunar surface yesterday. It repositioned itself by about 40 cm.
"Chandrayaan-3 Mission:
Efforts have been made to establish communication with the Vikram lander and Pragyan rover to ascertain their wake-up condition.
As of now, no signals have been received from them.
