Q. Consider the following statements regarding Suborbital Flight
1. Suborbital Flights occur when a spacecraft reaches space, but its velocity is such that it cannot orbit the Earth once they reach there.
2. The objects need to travel more than 28,000 km/hr to reach suborbital Flights.
Which of the above statements is/are correct?
Virgin Group founder Richard Branson and five others undertook a trip to the “edge of space”, and reached an altitude of 85 km from Earth before returning. Such a trip is called a Suborbital Flight.
- Suborbital Flights occur when a spacecraft reaches space, but its velocity is such that it cannot orbit the Earth once they reach there.
How does Suborbital Flight work?
- When an object travels at a horizontal speed of about 28,000 km/hr or more, it goes into orbit. Satellites need to reach that threshold speed in order to orbit Earth.
- Any object traveling slower than 28,000 km/hr must eventually return to Earth.
- However, Unity spacecraft traveled far enough to reach the “edge of space”. These are suborbital flights because they will not be traveling fast enough to orbit Earth once they reach there.
