Mostly we have seen space research through government authorities with huge amounts of investment ;but, spaceX was the live example for private startups who can develop rockets at lower prices than other government rockets investment. Its achievement has attracted the government now to invest in private startups in the space category .
EnduroSat : CubeSats:
Bulgarian startup EnduroSat CubeSats is a type of nanosatellite which is the most popular smallsat type currently in use, due to its affordability, modularity, and ease of development.
The dimension and cost of artificial satellites are determined by the complexity and nature of their payloads.The advancement in miniaturization of payloads, as well as reductions in assembly and launch costs, stimulates the growth of small satellites. Also known as smallsat, these satellites have a low mass, usually under 500 kilograms.
Kepler Communications : Satellite Constellation
Canadian startup Kepler Communications offers telecom services through its low-earth orbit (LEO) nanosatellite constellation. The startup uses a custom-built software-defined radio (SDR) to continuously enhance satellite features through software updates.
Analytical Space : Satellite Relay Network
The US-based startup Analytical Space is developing FastPixel, a relay network for satellites using nanosatellites. The startup uses CubeSat hybrid radio frequency-laser data relays to increase data throughput for satellites. FastPixel is backward compatible and is also capable of receiving data from a wide range of radio frequencies, enabling customers to extend their downlink capacities.
Orbex : Micro-Launch Vehicle
British startup Orbex is developing a recoverable and reusable micro-launch vehicle, with proprietary zero-shock stage separation technology, for low-cost orbital launches. The smallsat launch vehicle uses a 3D printed rocket engine, coaxial fuel tank, and carbon fiber or graphene composites for the main structures, and uses low-carbon bio-propane as fuel.
Aurora Propulsion Technologies : In-Space Propulsion System
Finnish startup Aurora Propulsion Technologies offers Orbital Thruster, a water-based resistojet propulsion module for small satellites. The multi-thruster system provides three-axis attitude control and customizable tank sizes, apart from variable thruster power requirements, and magnetorquers. The water-based propellant makes both the satellite launch and transport to the launch site safer.
Falcon 9 is a reusable, two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of people and payloads into Earth orbit and beyond. Falcon 9 is the world’s first orbital class reusable rocket. Reusability allows SpaceX to refly the most expensive parts of the rocket, which in turn drives down the cost of space access.
The Dragon spacecraft is capable of carrying up to 7 passengers to and from Earth orbit, and beyond. It is the only spacecraft currently flying that is capable of returning significant amounts of cargo to Earth, and is the first private spacecraft to take humans to the space station.
SpaceX’s Starship spacecraft and Super Heavy rocket (collectively referred to as Starship) represent a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond. Starship will be the world’s most powerful launch vehicle ever developed, with the ability to carry in excess of 100 metric tonnes to Earth orbit.
3D Fiber Printing Invention
3D Carbon Fiber Printing is new technology for use on Earth and in space. Developed by Northrop Grumman engineers, the patented solution is an additive manufacturing method called thermoplastic extrusion 3D printing to add fiber reinforcing to make stronger materials.
A-10 Thunderbolt II
was developed for the United States Air Force by the OEM Team from Fairchild Republic Company, now a part of Northrop Grumman Corporation Aerospace Systems Eastern Region located in Bethpage NY and St. Augustine FL. Following in the footsteps of the legendary P-47 Thunderbolt, the OEM Team was awarded a study contract in the 1960s to define requirements for a new Close Air Support aircraft, rugged and survivable, to protect combat troops on the ground.
there are many pitfalls to achieve in space to unfold many mysteries in space,stars and the universe . And with the advent of private companies taking over space now, there are not any limitations to achieve the heights in space.
