Question 2

What is the name of the oscillations that are amplitude-modulated structured narrow-band signals?

[A] Geomagnetic Pc1 pearl oscillations
[B] Geomagnetic Pc1 gold oscillations
[C] Geomagnetic Pc1 silver oscillations
[D] Geomagnetic Pc1 diamond oscillations

Answer 2

A [Geomagnetic Pc1 pearl oscillations ]

Notes:
The narrow-band signals known as geomagnetic Pc1 pearl oscillations are structured and have their amplitudes modulated. These signals are indications of low-frequency EMIC waves that result from wave-particle interactions in the Earth’s magnetosphere.
Researchers have observed significant increase in geomagnetic Pc1 pearl oscillations on the Earth’s surface in the recovery phase of the geomagnetic storms.

Question 3

Which institution developed the ‘StarBerrySense’ sensor?

[A] IIT Madras
[B] IISc Bengaluru
[C] IIA
[D] NIT Warangal

Answer 3

C [IIA]

Notes:
The StarBerrySense payload is a low-star sensor developed from off-the-shelf components by the Indian Institute of Astrophysics. It was successfully tested recently on board the PSLV C-55.
In its first space test, the sensor, which is mounted on the PSLV Orbital Experimental Module (POEM), is performing well, as per the Department of Space.

Question 5

What is the satellite which would be launched in partnership by Surrey Satellite Technology Ltd (SSTL) and Oxford Space Systems (OSS)?

[A] CarbSar
[B] Cryosat
[C] Spacesat
[D] UKSat

Answer 5

A [CarbSar]

Notes:
CrabSar is a satellite mission that is set to be launched by Surrey Satellite Technology Ltd (SSTL) and Oxford Space Systems (OSS) in partnership.
The satellite will consist of a Synthetic Aperture Radar (SAR) that enables high-resolution imaging from small satellite earth observation missions, irrespective of weather conditions or daylight.

Question 6

‘Saurona triangular and Saurona aurigera’, which were discovered recently, belong to which species?

[A] Snake
[B] Butterfly
[C] Spider
[D] Gecko

Answer 6

B [Butterfly]
Notes:
A new group of genus, Saurona, is named after the villain from The Lord of the Rings novels, Sauron. Two new butterfly species – Saurona triangular and Saurona aurigera – belong to this genus.
The team has also found another butterfly genus, which has been named Argenteria, meaning silver mine, on account of the silver scales on its wings.
