The ultraviolet imaging telescope of the Astrosat, India's first dedicated multi-wavelength space satellite, has spotted rare hot ultraviolet-bright stars in the Milky Way galaxy, a Ministry of Science and Technology statement said on Thursday (21 January).

These stars whose inner core is almost exposed, making them very hot, exist in the late stages of evolution of a Sun-like star. It is not clear how these stars end their lives as not many of them are detected in these fast-evolving phases, making their study crucial, the ministry said.

Gaganyaan’s first unmanned launch slated for December 2021


The launch of the first unmanned mission of Gaganyaan is slated for December, Finance Minister Nirmala Sitharaman said on Monday. The mission was originally scheduled for launch in December 2020 but had to be postponed due to the coronavirus pandemic.

In her budget speech, Sitharaman said as part of Gaganyaan, India’s manned space mission, four Indian astronauts are being trained on generic space flight aspects in Russia.

“The first unmanned launch is slated for December 2021,” Sitharaman said.


The Rs 10,000 crore Gaganyaan mission aims to send a three-member crew to space for a period of five to seven days by 2022 when India completes 75 years of independence.

The ISRO had started planning for the mission accordingly. The first unmanned mission was planned in December 2020, the second unmanned mission in June 2021.

The final and the main component, the manned mission of Gaganyaan, was scheduled six months later in December 2021, much before the 2022 deadline.

ISRO had earlier indicated that there would be a delay in several missions as the space body’s work has been hit by disruptions due to the coronavirus pandemic.

Among the major projects that have been affected are Chandrayaan-3 and Gaganyaan. Chandrayaan-3, the third mission to the moon, was scheduled in late 2020.

Staff members from ISRO’s different centres were infected with COVID-19 during the pandemic and only essential and process-related work was going on. The related industry was also affected due to the coronavirus lockdown.

Gaganyaan astronauts may splash off Gujarat coast after space flight

Gujarat may be honored to welcome the Gaganyaan astronauts when they return after their seven-day mission in space. Nilesh Desai, director of the Ahmedabad-based Isro Space Applications Center (SAC), said this in a presentation on Saturday hosted by Space Geeks Mumbai and other organizations.

“As of now, the mission is expected to land in Veraval in Gujarat in the Arabian Sea, and as a contingency measure even an area in the Bay of Bengal is being considered. The exact location will be finalized soon,” he said in the webinar .

The crew will be recovered in 15 to 20 minutes and, thereafter, they will be quarantined. “Only after they complete their quarantine period and return to work, can we declare the end of the mission,” he said. Veraval is known as a center of fishing industries in India and is 6 km from the famous Somnath temple.

Gaganyaan’s unmanned test mission is tentatively scheduled towards the end of the year, and the manned flight next year. The long-awaited takeoff will be from Sriharikota.

The program suffered a slight setback due to the Covid-19 pandemic.

Desai said the size of the crew module has been reduced slightly due to the weight limitations of the GSLV Mark 3 rocket.

With a crew of two or three, who trained in Russia, the flight will operate in low earth orbit for 275-400 km, passing over India twice in the morning and twice at night. Throughout the week-long mission, the Isro master control facility in Hassan in Karnataka and the telemetry, tracking and command network in Bengalaru will communicate with the crew, in addition to different communication channels via satellites.

With considerable emphasis on crew safety, Isro evaluates by humans all subsystems of the orbiter module in which the crew will fly, as well as the launch vehicle and launch pad. Desai also announced that the Chandrayaan-2 orbiter’s mission duration has been extended to 7.5 years due to excellent fuel management. “Long life will provide an opportunity for lunar mapping and scientific payloads will generate new knowledge about the moon,” he said.

India has launched 328 satellites from 33 different countries till date: Dr Jitendra Singh



Union Minister of State (Independent Charge) Development of North Eastern Region (DoNER), MoS PMO, Personnel, Public Grievances, Pensions, Atomic Energy and Space, Dr.Jitendra Singh said that Rs 900 Crore was allocated to ISRO for F.Y. 2020-21for developing capacity for launching of satellites. In a written reply to a question in the Lok Sabha, he said that the Department of Space has been involved in launching satellites of foreign countries since long. Total number of satellites launched till date is 328 from 33 different countries and the revenue earned till date is 25 M USD and 189 M Euros. Moreover, Government of India has established NewSpace India Limited (NSIL), a PSU under Department of Space to commercially launch satellites and become financially self-reliant.


ISRO is striving towards achieving Atmanirbharta in the field of capacity development in launching satellites; therefore, no policy is envisaged for seeking foreign cooperation in this direction.


In another related question, Dr Jitendra Singh said that ISRO facilities are extended to Indian industries and academia for testing their space systems. Satellites from M/s. Space Kidz India and M/s. Syzygy Space Technologies have undergone testing at UR Rao Satellite Centre, ISRO. He said, participation of private sector in space activities in India is expected to result in development of cutting edge Technologies, new applications & services. Overall it will make a bigger impact on space economy, he added.


The Minister said that Government has analysed the issues and concerns about national security while allowing Private companies to participate in space activities and appropriate measures have been taken by means of establishing Indian National Space Promotion and Authorisation Center (IN-SPACe), an independent nodal agency to authorize, monitor and regulate space activities in the country.

Isro plans new propulsion for deep space missions

Indian Space Research Organisation (Isro) is exploring the possibility of developing a new propulsion technology to fuel spacecraft for its future deep space missions.



ISRO is in the process of developing 100W Radioisotope Thermoelectric Generator (RTEG) without radio isotope.’ Isro calls it alpha source thermoelectric propulsion technology.

RTEG will have less mass than solar cells of equivalent power and allow more compact spacecraft that can navigate easier in space. Many missions of Nasa and Russia, Besides China’s 2013 Chang’e 3 mission to the moon and its rover Yutu had used RTG.

It will be useful for long duration missions where alternative energy is not available. the development of RTEG is taken up as it is envisaged that it will be a part of Isro’s deep space missions for power generation and thermal management. the system will be capable of operating in vaccum conditions of deep space, dusty, carbon dioxide-rich and corrosive environments. Isro says the RTG’s weight should be 20 kgs or less, with a life span of 20 years or more and survive indefinitely without damage when stored in the atmosphere at temperatures as high as 50 degrees Celsius.

The system should be safe for human handling in close vicinity under all conditions even with nuclear fuel concealed inside … the unit should be resilient to any pre-launch or post-launch explosion so as to not cause any nuclear contamination in the environment. that means ISRO also working in Nuclear propulsion .



After another Mars mission, Isro could be eyeing Jupiter, Saturn, Neptune and Uranus.
