Dazzling Nighttime Rocket Launch Puts 29 Satellites In Orbit, a New Record
A spectacular rocket launch from Virginia's eastern shore late Tuesday (Nov. 19) lit up the night sky like an artifical sun, kicking off a record-breaking mission to put 29 satellites into orbit.
The Orbital Sciences-built Minotaur 1 rocket launched into space at 8:15 p.m. EST (0115 GMT Wednesday) from NASA's Wallops Flight Faciltiy in Virginia to begin the ORS-3 mission, which is run by the U.S. military's Operationally Responsive Space Office. The launch was expected to be visible to millions of observes along the U.S. East Coast, weather permitting.
After a 45-minute delay caused by an issue with a downrange tracking station, the Minotaur 1 roared to life, carving an arc of flame into the night sky that was likely visible along the East Coast from Maine down to Florida, and from as far inland as Indiana and Michigan, according to viewing maps provided by NASA and Orbital Sciences.

The rocket toted a total of 29 satellites — the most ever delivered to orbit in a single launch, mission officials said. A so-called "PhoneSat" built by NASA and the first-ever satellite designed and built by high school students were among the spacecraft hitching a ride into orbit on the four-stage Minotaur 1 rocket.
ORS-3's primary payload was the U.S. Air Force's $55 million STPSat-3, which carries five separate experiments and sensors that will measure various aspects of the space environment. STPSat-3 is the second spacecraft launched under the military's Standard Interface Vehicle program, which aims to help reduce the cost and preparation time of key satellite missions.
"We continuously search for affordable launch options, including rideshare opportunities on government and commercial missions," Col. Todd Krueger, director of the Defense Department's Space Test Program, told reporters during a pre-launch press conference on Nov. 14.
"The ORS-3 mission is a critical opportunity for the Space Test Program to conduct more space R&D," Krueger added. "The projects that we're flying on ORS-3 will benefit tomorrow's national security space architecture by studying the space environment and providing advanced capabilities for the warfighter."
The other 28 satellites lofted by the Minotaur 1 are tiny craft called cubesats, which were built by a variety of institutions for a broad range of purposes. TJ3Sat, for example, is the first satellite designed and built by high-school students ever to reach orbit. (The students attend Thomas Jefferson High School for Science and Technology in Alexandria, Va., hence the name.)
NASA's Ames Research Center in Moffett Field, Calif., provided PhoneSat 2.4, the next step in the space agency's efforts to demonstrate the utility of cheap spacecraft based on off-the-shelf commercial smartphones.
NASA also contributed Firefly, a cubesat that will study lightning flashes around the globe.
"Firefly will gather up to a year of observations on the mysterious workings of lightning," Firefly principal investigator Doug Rowland, of NASA's Goddard Space Flight Center in Greenbelt, Md., said in a statement. "Lightning is so familiar we tend to take it for granted, but we really don’t know the details of how it works — even though it is a critical part of the global electric circuit, and has obvious social and technological effects."

In addition to the 29 satellites launched aboard the Minotaur 1 rocket, three other cubesats were deployed in orbit on Tuesday. Those three tiny satellites were launched from the Kibo Japanese laboratory on the International Space Station, NASA officials said. That brings the total number of cubesats launched on Tuesday up to 31 satellites, not including the larger STPSat-3. A fourth cubesat is due to be deployed from the International Space Station on Wednesday (Nov. 20).
