NASA confirmed the safety of the scheduled spacecraft earlier today. It’s expected to collide with comet Tempel 1 in space, so researchers can better understand the concept of life on Earth.

The Deep Impact spacecraft is currently 1.5 million miles away from its target, but is on schedule to collide against Tempel 1 on Monday, July 4th. The Deep Impact spacecraft has already provided scientists with preliminary images of its target. The spacecraft would launch a small sized impactor, which would blast the comet. The comet is expected to be as big as a stadium.

"Both the fly-by and the impactor spacecraft are healthy and ready for encounter operations," said Dave Spencer, Mission Manager, Deep Impact.

NASA said it’s ready with a back-up plan should there are complications in the end. One of such plans includes the blast with both the impactor as well as the spacecraft.

NASA said the plan of the mission is to study various aspects of the comet with photographs. According to the space organization, the photographs of material that has not come in contact with light for 4.6 billion years would prove to be intriguing.

The 771lbs copper-fortified compactor is expected to hit the comet at 1:52 a.m. EDT on Monday at 23,000 mph. The main craft would be 310 miles away from the collision and have 13 minutes to take photographs of the incident.

The collision will be observed via Hubble, Spitzer and Chandra space telescopes.
