  • A rocket made almost entirely of 3D-printed parts started its first flight late Wednesday but failed to reach orbit.
  • 2
  • The 33-meter-long rocket, called Terran 1, took off from Cape Canaveral, Florida.
  • 3
  • The startup company Relativity Space created 85 percent of the rocket using 3D printing technology.
  • 4
  • Most parts came from the company's large printing center in Long Beach, California.
  • 5
  • Terran 1 took off successfully and stayed in the air for three minutes.
  • 6
  • The first stage, or lower part, of the rocket launched and separated as planned.
  • 7
  • The upper stage, however, appeared to ignite and then shut down, sending it crashing into the Atlantic Ocean.
  • 8
  • Relativity Space had hoped for the rocket to stay in orbit for several days before falling through Earth's atmosphere and burning up.
  • 9
  • It was the second failed launch by Relativity Space this month.
  • 10
  • The company called off an attempt 12 days ago just seconds before takeoff.
  • 11
  • Though the rocket did not reach orbit, the company said it was pleased with the launch.
  • 12
  • Arwa Tizani Kelly works for Relativity Space and discussed the launch.
  • 13
  • Kelly said that "(first) launches are always exciting and today's flight was no exception."
  • 14
  • Although other space businesses use 3D-printed materials, the pieces make up only a small part of their rockets.
  • 15
  • Relativity Space was founded in 2015 by two young engineers.
  • 16
  • The company said it is working to develop larger versions of the rocket that will have even more 3D-printed material.
