The Falcon Heavy launch: the most powerful operational rocket in the world

Context

Recently, SpaceX launched the Falcon Heavy rocket into geosynchronous Earth orbit.

About

More about the current mission

The rocket is carrying satellites to space for the U.S. military in a mission named U.S. Space Force (USSF)-44.
The mission deployed two spacecraft payloads:
- One of which is the TETRA 1 microsatellite created for various prototype missions in and around the geosynchronous earth orbit.
- The other payload is for national defense purposes. It will place the satellites for the Space Systems Command’s Innovation and Prototyping.

Geosynchronous orbit (GEO):

A geosynchronous orbit (GEO) is a low inclination orbit about Earth having a period of 23 hours 56 minutes 4 seconds.
The synchronization of rotation and orbital period means that, for an observer on Earth's surface, an object in geosynchronous orbit returns to exactly the same position in the sky after a period of one sidereal day

About Falcon Heavy:

Falcon Heavy is the most powerful operational rocket in the world by a factor of two.
The rocket has a height of 70 m, a width of 12.2 m, and a mass of 1,420,788 kg.
It has the ability to lift into orbit nearly 64 metric tons (141,000 lb).
Falcon Heavy can lift more than twice the payload of the next closest operational vehicle, the Delta IV Heavy.
Falcon Heavy is composed of three Falcon 9 nine-engine cores whose 27 Merlin engines together generate more than 5 million pounds of thrust at liftoff, equal to approximately eighteen 747 aircraft.
Merlin engines: Merlin is a family of rocket engines developed by SpaceX for use on its Falcon 1, Falcon 9, and Falcon Heavy launch vehicles.
- Merlin engines use RP(Rocket Propellant)-1 and liquid oxygen as rocket propellants in a gas-generator power cycle. The Merlin engine was originally designed for recovery and reuse.
- These engines were designed for recovery and reuse.
The company hails this as the most powerful operational rocket in the world, afterSaturn V.
This is the fourth launch of the giant rocket system.
However, it is the first one in nearly three years since its last launch in 2019.

When was the Falcon Heavy launched?

SpaceX last launched its Falcon Heavy rocket in June 2019 from NASA’s Kennedy Space Center.
It carried 24 satellites as part of the Department of Defense’s Space Test Program-2.

The curse of poor geography

India’s capital city lies to the
- north-east of the Thar Desert
- north-west of the central plains
- south-west of the Himalayas
As winds arrive from the coasts, bringing with them pollutants picked up along the way, they get ‘trapped’ right before the Himalayas.
The air pressure pushes from one direction, and with the inability to escape quickly in the other, the particulate matter accumulates over the northern plains.
This accumulation and entrapment affect not only Delhi but the entire expanse between Punjab in the west to West Bengal in the east.

Earth's closest-ever black hole found, is 10 times the size of the Sun

Astronomers working at the International Gemini Observatory in the US have found a black hole, named Gaia BH1 that lies closest to the Earth.
It is the first-ever detected dormant stellar-mass black hole of the Milky Way galaxy.
Its size is 10 times that of the Sun in our solar system.
It's located 1600 light-years away.
The team used the International Gemini Observatory, operated by NSF's NOIRLabin the US.
