Who has been successfully tested solid fuel-based booster stage of SSLV?

A)

ISRO

B)

NASA

C)

Roscosmos

D)

European Space Agency

Correct Answer : ISRO

THE INDIAN Space Research Organisation (ISRO) on Monday(14th Mar 2022) successfully completed the ground test of the solid-fuel based booster stage (SS1) of its new Small Satellite Launch Vehicle (SSLV), completing the ground testing of all three stages of the launch vehicle. The new launch vehicle is now ready for its first development flight, which is scheduled for May this year.

“The successful test of solid booster stage has given sufficient confidence to proceed with the first developmental flight of SSLV (SSLV-D1), which is scheduled in May 2022. The remaining stages of SSLV i.e. SS2 & SS3 stages have successfully undergone necessary ground tests and are ready for integration,” the space agency said in a statement.

The space agency usually declares a launch vehicle operational after two successful development flights.

The SSLV was designed to be smaller, cheaper, and quickly assembled for commercial launches on demand. The SSLV is likely to cost R 30 crore as compared to Rs 120 crore for each Polar Satellite Launch Vehicle (PSLV), which is India’s workhorse. It can be assembled by a team of six within seven days in comparison to a team of 600 that takes a couple of months to assemble a PSLV.

The launch vehicle will carry smaller payloads of about 500 kg in comparison to 1,750 kg carried by PSLV.

The SSLV launch, which was initially planned for 2020 end, has been repeatedly pushed as the pandemic resulted in fewer missions for ISRO – just four launches in the last two years. The delays, experts say, will result in India losing its global market share..

Which country has successfully launched a military satellite, "Noor-2", into orbit at an altitude of 500 kilometres (311 miles) from the earth?

A)

Israel

B)

Pakistan

C)

Iran

D)

Saudi Arabia

Correct Answer : Iran

Iran's Islamic Revolutionary Guard Corps (IRGC) has successfully put a second military satellite, the Noor 2, into orbit, the state-media said on Tuesday(8th Mar 2022).

The announcement came as talks held in Vienna to revive an agreement restraining Iran's nuclear program have reached a critical stage.

Noor 2 is orbiting at an altitude of 500 kilometres (311 miles). The first military satellite, launched by the Islamic Republic in April 2020, placed the Noor, or "light" in Persian, at an orbit of 425km (265 miles) above the earth’s surface.

Putting a second satellite in space would be a major advance for Iran’s military, raising concerns about the country's nuclear and missile programs.

Iran will send a series of military satellites into orbit over the coming years, Space Commander of the Revolutionary Guards' Aerospace Force Ali Jafarabadi said on Tuesday(8th Mar 2022)..

A)

China

B)

Russia

C)

Ukraine

D)

South Korea

Correct Answer : Russia

Russia has reportedly released a propaganda video that shows Russian cosmonauts disconnecting the Russian ISS modules from the International Space Station.

A)

NASA

B)

ISRO

C)

Roscosmos

D)

China space agency (CNSA)

Correct Answer : NASA

The US space agency, NASA, successfully launched the third in a series of four next-generation weather satellites, Geostationary Operational Environmental Satellite (GOES), from Cape Canaveral Space Force Station, Florida on March 01, 2022. The satellite is named as GOES-T. Once the satellite gets positioned in its geostationary orbit it will be renamed from GOES-T to GOES-18.

Which country Launches "Long March-8 Rocket" 22 Satellites into Space in Feb 2022?

A)

India

B)

Japan

C)

Brazil

D)

China

Correct Answer : China

China launched a Long March-8 rocket to place 22 satellites in space on Sunday(27th Feb 2022), setting a domestic record for the most spacecraft launched by a single rocket.

The rocket blasted off at 11.06 a.m. (Beijing Time) at the Wenchang Spacecraft Launch Site in the southern Hainan Province before sending the satellites into preset orbits, Xinhua news agency reported.

These satellites will be mainly used for commercial remote sensing services, marine environment monitoring, forest fire prevention and disaster mitigation.

The mission marked the 409th flight of the Long March carrier rockets.

ISRO successfully launched which Earth observation satellite in its first launch in 2022?

A)

EOS-02

B)

EOS-03

C)

EOS-04

D)

EOS-05

Correct Answer : EOS-04

The Indian Space Research Organisation (ISRO) successfully launched the earth observation satellite EOS-04 in the early hours of Monday(14th Feb 2022), along with two other satellites, on the PSLV-C52 mission. This is ISRO’s first launch of the year, and follows the failed launch of the EOS-03 satellite in August last year(2021).

â€‹The EOS-04, formerly known as RISAT-1A, is a land-based earth observation satellite that images using radar. It functions in all weather conditions and is used for agricultural and forestry applications like terrain mapping and soil moisture monitoring. On Monday, it was inserted into a sun synchronous orbit at an altitude of 529 km from the surface.

EOS-04 is the sixth satellite to be launched under the RISAT (Radar Imaging Satellite) programme in the last decade.

The two other satellites were INS-2TD, a technology demonstrator from ISRO with a thermal imaging camera, and INSPIREsat-1, a student satellite developed by the Indian Institute of Space Technology (IIST) to study the ionosphere.â€‹

â€‹The satellites were launched on the PSLV, which lifted off at 05.59 am from the first launch pad at Sriharikota. It was the 23rd flight of the PSLV in its XL configuration with six strap-on motors. Overall, it is the 54th flight of a PSLV rocket and the 80th launch from Satish Dhawan Space Centre. â€‹

“The primary satellite, EOS-04 has been put in a very precise orbit by PSLV-C52. Co-passenger satellites INS-2TD and INSPIREsat-1 have also been placed in the right orbits. This spacecraft is going to be one of the biggest assets to serve the country. We will be back again with another launch of PSLV very soon,” new ISRO chief S. Somanath â€‹said in a press conference following the launch.

Who is decommissioned INSAT-4B through 11 Re-orbiting manoeuvres?

A)

NASA

B)

ISRO

C)

JAXA

D)

Roscosmos

Correct Answer : ISRO

Amid the growing concern over junk in outer space, the Indian Space & Research Organisation (ISRO) successfully disposed of one of its satellites after it completed its operational life in orbit. The INSAT-4B underwent Post Mission Disposal (PMD) at the end of its service, followed by decommissioning on January 24, 2022, Isro said.

"INSAT-4B is the 21st Indian Geostationary Earth Orbit (GEO) satellite to undergo post-mission disposal, the required propellant for such re-orbiting was included in the initial fuel budget as a part of standard practice followed in ISRO's GEO mission planning," Isro said in a statement.

The development is in compliance with the UN and the Inter-Agency Space Debris Coordination Committee (IADC) recommended space debris mitigation guidelines. The IADC guidelines provide guidance for limiting the generation of orbital debris both during and after space operations. The guidelines also define accepted disposal orbits and other conditions, such as the timeline for abandoning commonly used orbits and controlling the risk to people and property on the Earth.

Isro added that the successful post-mission disposal of INSAT-4B through meticulous planning and flawless execution marks yet another endeavour by the space agency to ensure the safety and sustainability of outer space operations.
