In a groundbreaking experiment, NASA has successfully sent a 15-second video of an orange tabby cat named Taters chasing a laser pointer dot in ultra-HD. The video traveled almost 19 million miles from a probe back to Earth. This was part of a NASA experiment to test the possibility of sending streaming video through deep space, ____ a laser-based communication system called Deep Space Optical Communications (DSOC). The video was added to the Psyche probe, which was ____ in October on a six-year mission to visit an asteroid. On December 11, it sent the video back to Earth in just 101 seconds. This marked a significant achievement in the field of space communication, demonstrating the ____ of laser technology in transmitting data across vast distances in space. The implications of this experiment are far-reaching. It has set a precedent for future space missions, opening up the possibility of transmitting broadband video across millions of miles. This could significantly enhance our capabilities in space exploration and scientific research, facilitating more ____ missions in the future.

## Answer

In a groundbreaking experiment, NASA has successfully sent a 15-second video of an orange tabby cat named Taters chasing a laser pointer dot in ultra-HD. The video traveled almost 19 million miles from a probe back to Earth. This was part of a NASA experiment to test the possibility of sending streaming video through deep space, **using** a laser-based communication system called Deep Space Optical Communications (DSOC). The video was added to the Psyche probe, which was **launched** in October on a six-year mission to visit an asteroid. On December 11, it sent the video back to Earth in just 101 seconds. This marked a significant achievement in the field of space communication, demonstrating the **potential** of laser technology in transmitting data across vast distances in space. The implications of this experiment are far-reaching. It has set a precedent for future space missions, opening up the possibility of transmitting broadband video across millions of miles. This could significantly enhance our capabilities in space exploration and scientific research, facilitating more **ambitious** missions in the future.

## Explanation

Blank 1 follows a comma and tells how the video was sent, so the -ing form "using" is right. "To use" signals a purpose, and "use" is a bare verb with no subject. In blank 2, probes and rockets are "launched." "Initiated" and "established" go with plans or groups, not spacecraft.

## Hints

- Look at the words immediately before and after the blank to determine the necessary part of speech.
- Consider the scientific tone of the passage; choose words that reflect professional terminology.
