Explanation:

Nepal plane crash: black box recovered from accident site

• Both the cockpit voice recorder and flight data recorder have been recovered.
• The Black Box, technically known as Flight Data Recorder, is an instrument that records all the activities of an aeroplane/ aircraft during its flight. An aeroplane generally houses two black boxes, one at the front and another on the back of an aircraft.

The Black Box has two separate boxes:

Flight Data Recorder:

This box can contain information about direction, altitude, fuel, speed, turbulence, cabin temperature etc. About 88 such values for about 25 hours can be recorded. This box can withstand a temperature of about 11000°C for one hour and a temperature of 260°C for 10 hours. These boxes are red or pink in colour so that can be found easily.

Cockpit Voice Recorder:

This box records the sound of the airplane during the last two hours. It records the sound of engine, emergency alarm, cabin and cockpit in order to predict the conditions of the plane before any accident occurred.

How does a Black Box work?

• Black Box is made of Titanium metal and is enclosed in a Titanium box which gives it the strength to withstand any shock if it falls in the sea or falls from the height.
• It can work for 30 days without any electricity. It can withstand a temperature of 11000°C. When this box is lost anywhere, it keeps on emitting the waves along with a beep sound for about 30 days.

• This voice can be identified by the investigators from a distance of about 2-3 An interesting fact with regard to the Black box is that it can emit waves from the depth of 14000 feet in the sea.
• Though a black box does not reflect a clear picture of plane accidents and in some of the accidental cases it could hardly be found but one fact is for sure that it plays an important role in the investigation of plane accidents.

Q3.   Consider the following  statements about the Venus exploration missions

1. Optimal launch windows from earth to Venus occur once around every 19 months.
2. The S. and the European space agencies have Venus missions VERITAS and EnVision respectively.

Which of the above statements is/are correct?

1. 1 only
2. 2 only
3. Both 1 and 2
4. Neither 1 nor 2

Answer (c)

Explanation:

ISRO likely to push Venus mission ‘Shukrayaan I’ to 2031

• The organisation is yet to receive approval from the Union government for the Venus mission and that the mission could as a result be postponed to 2031.
• ISRO’s Venus mission, Shukrayaan I, was expected to be launched in December 2024. The idea was born in 2012. Shukrayaan I will be an orbiter mission.
• ISRO had originally hoped to launch Shukrayaan I in mid-2023 but cited the pandemic when it pushed the date to December 2024. Other ISRO missions, including Aditya L1 and Chandrayaan III, have also been affected by manufacturing delays and commercial launch commitments.
• Optimal launch windows from earth to Venus occur once around every 19 months. This is why ISRO has “back-up” launch dates in 2026 and 2028, should it miss the 2024 opportunity. But even more optimal windows, which further reduce the amount of fuel required at lift-off, come around every eight years.
• The S. and the European space agencies had Venus missions planned for 2031 — referring to VERITAS and EnVision, respectively.

ASI begins excavations at Purana Qila

• The Archaeological Survey of India (ASI) will soon undertake a third round of excavations at Purana Qila. The 16th-century fort complex was built by Sher Shah Suri and Mughal emperor Humayun.

• During the closure of the previous season’s excavation, evidence of layers predating the Mauryan period was found. During this season’s excavation, the focus will also be to accomplish the traces of Painted Grey Ware finding in stratigraphic context.
• The findings and artefacts unearthed in earlier excavations comprise Painted Grey Ware from 900 BCE, an earthen pottery sequence from Maurya to Shunga, Kushana, Gupta, Rajput, Sultanate and Mughal periods.
• Excavated artefacts such as sickles, parers, terracotta toys, kiln- burnt bricks, beads, terracotta figurines, seal and dealings that were excavated earlier are currently displayed at the Archaeological Museum inside the fort complex.

Answer (d)

Explanation:

Emergence of New States

With the decline in the authority of the Mughal emperors, the governors of large provinces, subadars, and the great zamindars consolidated their authority in different parts of the subcontinent. Through the eighteenth century, the Mughal Empire gradually fragmented into a number of independent, regional states.

Broadly speaking the states of the eighteenth century can be divided into three overlapping groups:

1. States that were old Mughal provinces like Awadh, Bengal and Although extremely powerful and quite independent, the rulers of these states did not break their formal ties with the Mughal emperor.
2. States that had enjoyed considerable independence under the Mughals as watan These included several Rajput principalities.
3. The last group included states under the control of Marathas, Sikhs and others like the Jats. These were of differing sizes and had seized their independence from the Mughals after a long-drawn armed struggle.
