Use of liq nitrogen is required in that case. It should be allowed to flow out from the vents to reduce the outer body temperature.

Not really effective and Further adds complexity and costs, space is cold as *censored*, it's space will little to no heat( well technically little bit due to radiation of matter and sun), plus liquid nitrogen supply on the satellite will be very limited, and you can't just reuse the liquid nitrogen, it will get hot itself if reuse happened multiple times.
Plus the sats that will be targeted will be Large ones with radars and sensors.
Smaller communication sats will be too numerous to effectively destroy with expensive asat weapons.
Making radars sats more cheaper, and quickly launching replacement for destroyed/out of work one is a better option
If space is cold it makes the job easy. Shutting down all the equipment will make it cold. The only issue is to restart it. Once you know how to do it it can be managed. It is a new domain of research though.
Replacing is economical and for now better option since there is no expertise in the above.
Na, man it's lot more complex than you think.
Not a topic for us to seriously discuss.

India beefing up space-based surveillance after border conflict
India spy satellites: India plans to deploy as many as 150 new satellites to boost border security, reports said citing Indian Space Research Organisation (ISRO) Chairman V Narayanan. The estimated cost of placing 150 satellites is about Rs 26,000 crore ($2.8 billion), the reports added.
India plans to launch over 50 spy satellites and add night-time imaging to enhance its national security capabilities, people familiar with the matter said, after New Delhi encountered surveillance blind spots during a border conflict last year with neighbour Pakistan.
The Narendra Modi-led administration is also looking to build ground stations overseas to relay information more quickly and comprehensively, said the people who asked for anonymity to discuss confidential matters. These could be in the Middle East, Southeast Asia and Scandinavia, they said, though local government approval would be required.
Plans are underway to enhance its own satellites with newer technology capable of capturing images in dark, cloudy conditions by moving from electro-optical radar to synthetic aperture radar, the people said. Upgrades are also being worked on to help transfer data from one satellite to another without relying on a ground station, they added.
The launch of the first 52 satellites, under Space-Based Surveillance-3, is being fast-tracked to monitor places of interest more frequently than India’s current technology allows, the people said. The Times of India, which reported in June on the plan to expedite the satellite launch, said the first batch may go up by April.
India plans to deploy as many as 150 new satellites to boost India’s border security, Mint reported in April citing Indian Space Research Organisation, or ISRO, Chairman V Narayanan at an event in Chennai. The estimated cost of placing 150 satellites is about Rs 26,000 crore ($2.8 billion), they added.
Lessons Learned
The wide-ranging measures underscore the lessons learned by India after the nuclear-armed South Asian neighbours faced off in May in their worst military confrontation in decades. India also wants to develop so-called bodyguard satellites to identify and counter threats to orbiting spacecraft, Bloomberg News reported in September, as part of overall efforts to plug any capability gaps.Satellites were used extensively to identify and monitor targets during that four-day showdown, which put the two nations on the brink of all-out war. China provided Pakistan with support during the fighting, helping Islamabad adjust its satellite coverage, a research group under India’s Ministry of Defence said last year.
India has more than 100 satellites in orbit compared to just eight for Pakistan, according to spacecraft data tracker N2YO.com.
India’s satellites are blind at night or in cloudy conditions, a lacuna highlighted during Operation Sindoor against Pakistan last year. Chinese satellites are capable of sending night images.
Currently, the gap in sweeping a particular area runs in days. That meant India had to procure satellite data from US-based companies to plan attacks against Pakistan last year, the people said.
Having these additional spy satellites can potentially reduce the gap to a few hours, they said.
India’s security agencies have asked private startups to develop so-called bodyguard satellites as the country accelerates efforts to protect space assets at a time of heightened geopolitical tensions, according to people familiar with the matter.
Discussions between government bodies and startups are in advanced stages and the private companies are aiming to launch their first test satellite in the first half of this year, said the people, who asked not to be identified as the information isn’t public. These are meant to escort, protect and counter orbital threats to high-value spacecraft.
Additional launches are expected by the end of this year or early next year and the technology is likely to then be acquired by government agencies, which will develop more of the bodyguard satellites, they said.
India has become increasingly concerned about the national security threat posed by foreign spacecraft after a border conflict last year with neighbor Pakistan. During the hostilities, China provided Pakistan with satellite support, helping Islamabad adjust its radar and air defense systems more effectively, a research group under India’s defense ministry said in May.
The desire to enact safeguards was kickstarted by a near-miss 2024 incident in which a spacecraft from an unidentified neighboring country came within 1 kilometer (0.6 miles) of an Indian satellite performing tasks that could have military applications such as mapping and monitoring of on-ground objects, Bloomberg News reported in September.
The efforts took on fresh urgency for Prime Minister Narendra Modi’s administration following last year’s military confrontation with Pakistan that put the two nations on the brink of an all-out war. Satellites were used extensively to identify and monitor targets during the four-day showdown, which also revealed some shortcomings that New Delhi is now plugging by bolstering its surveillance system.

‘Probability of Disruption’
“The probability of satellites being disrupted is definitely there,” said Anil Bhatt, a former chief of military operations, who is now the director general at the Indian Space Association. “Every nation that wants to be a serious player in the critical space domain will need to build kinetic and non-kinetic capabilities to protect its own assets.”
China is practicing “dogfighting” satellites as its space prowess continues to expand, CNN reported in March 2025 quoting a United States Space Force official.
Security concerns have been exacerbated by China’s growing significance as a space superpower and its technological prowess. The country has more than 1,100 active satellites compared with just over 100 for India, according to data from tracking site N2YO.com.
China, which continues to have a fragile relationship with India despite a recent thaw, has been experimenting with bodyguard satellites for quite sometime now and has likely developed capabilities to physically disrupt or connect with other satellites, the people said.
India has been discussing space cooperation, including real-time tracking and monitoring of satellites, with countries including France and the United Arab Emirates, one person said.
Indian startups are looking to develop two types of bodyguard satellites. One model has a robotic arm that can hook into and physically move spacecraft India views as undertaking hostile actions. The second type is designed to tackle smaller satellites that are attacking Indian space assets by enclosing them — forming a box around them — and then moving them away.

‘Eye in The Sky’
The satellite-protection project is part of a bigger effort by Modi’s government to develop more security assets in orbit.
It has fast-tracked the Space-Based Surveillance program that aims to launch more than 50 spy satellites and add night-time as well as all-weather imaging. In the longer term, India’s space agency and private partners plan to deploy up to 150 new satellites to ensure a comprehensive “eye in the sky” over the nation’s borders.
India is expanding its ground infrastructure too by building stations at home and in strategic overseas locations to monitor foreign spacecraft and ensure near-instantaneous data transfers.
