The Anomalous Transport Rocket Experiment (ATREX) is a heliophysics experiment that was conducted by NASA's Goddard Space Flight Center out of the Wallops Flight Facility located on the Eastern Shore of Virginia. [1] The mission entailed the use of 5 sounding rockets launched closely in time together, each of which released a chemical tracer into the high-altitude jet stream.
The rocket launches were widely visible to residents of the Eastern seaboard from as far north as New York to as far south as North Carolina, while the tracers were visible throughout the Eastern seaboard. [2] ATREX principal investigator Miguel Larsen said of the chemical tracer release: "They occur in the middle of the night, and they glow, It's not extremely bright, but it's definitely visible." [3]
The mission operating window was set from March 14 to April 3, 2012, with launch windows expected to occur between 11:00 pm and 6:30 am the following morning, local time. [4] The first launch attempt was cancelled due to internal radio frequency interference on one of the instrumented payloads. The malfunction was detected during preparations for the launches during the evening of March 14. [5] Five other launch attempts were subsequently cancelled, primarily due to weather. The launch attempt that took place on the evening of March 20–21 reached T-15 minutes before being put on hold and subsequently canceled due to an equipment problem and weather conditions.
The launch took place just before the launch window closed for the mission at 5 a.m. EDT, Tuesday, March 27, 2012. [6]
The mission used two Terrier Improved Malemute, two Terrier Improved Orion, and one Terrier Oriole sounding rockets. [1] The rockets were launched within a span of 5 minutes and 20 seconds, with one rocket launched every 80 seconds. [7] All five released their chemical tracer payload, which is made up of trimethyl aluminum, [3] at roughly the same time while at slightly different altitudes. Two of the rockets also carried instruments in order to measure atmospheric pressure and temperature, [1] while three different cameras located in North Carolina, New Jersey, and Wallops Flight Facility, tracked the tracers in order to measure how quickly they move away from each other.

STS-80 was a Space Shuttle mission flown by Space Shuttle Columbia. The launch was originally scheduled for October 31, 1996, but was delayed to November 19 for several reasons. Likewise, the landing, which was originally scheduled for December 5, was pushed back to December 7 after bad weather prevented landing for two days.
STS-105 was the 30th mission of Space Shuttle Discovery, in which Discovery went to the International Space Station. It launched from Kennedy Space Center, Florida, on 10 August 2001. This mission was Discovery's final mission until STS-114, because Discovery was grounded for a refit, and then all Shuttles were grounded in the wake of the Columbia disaster. The refit included an update of the flight deck to the glass cockpit layout, which was already installed on Atlantis and Columbia.
Pegasus is an air-launched multistage rocket developed by Orbital Sciences Corporation (OSC) and later built and launched by Northrop Grumman.

The Lunar Atmosphere and Dust Environment Explorer was a NASA lunar exploration and technology demonstration mission. It was launched on a Minotaur V rocket from the Mid-Atlantic Regional Spaceport on September 7, 2013. During its seven-month mission, LADEE orbited the Moon's equator, using its instruments to study the lunar exosphere and dust in the Moon's vicinity. Instruments included a dust detector, neutral mass spectrometer, and ultraviolet-visible spectrometer, as well as a technology demonstration consisting of a laser communications terminal. The mission ended on April 18, 2014, when the spacecraft's controllers intentionally crashed LADEE into the far side of the Moon, which, later, was determined to be near the eastern rim of Sundman V crater.
Cygnus is an expendable American automated cargo spacecraft designed for International Space Station (ISS) resupply missions. It was initially developed by Orbital Sciences Corporation with financial support from NASA under the Commercial Orbital Transportation Services (COTS) program. To create Cygnus, Orbital paired a pressurized cargo module, largely based on the Multi-Purpose Logistics Module, built by Thales Alenia Space and previously used by the Space Shuttle for ISS resupply, with a service module based on Orbital's GEOStar, a satellite bus. After a successful demonstration flight in 2013, Orbital was chosen to receive a Commercial Resupply Services (CRS) contract. A larger Enhanced Cygnus was introduced in 2015. Orbital Sciences merged into Orbital ATK in 2015; Northrop Grumman purchased Orbital ATK in 2018 and has continued to operate Cygnus missions. A further enlarged Mission B Cygnus is expected to be introduced in 2025.
