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]

Mission details

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 Longest duration Space Shuttle mission

STS-80 was a Space Shuttle mission flown by Space Shuttle Columbia. The launch was originally scheduled for 31 October 1996, but was delayed to 19 November for several reasons. Likewise, the landing, which was originally scheduled for 5 December, was pushed back to 7 December after bad weather prevented landing for two days.

STS-105 Space Shuttle mission to the International Space Station

STS-105 was a mission of the Space Shuttle Discovery to the International Space Station, launched from Kennedy Space Center, Florida, 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 launch vehicle developed by Orbital Sciences Corporation (OSC) and now built and launched by Northrop Grumman. Capable of carrying small payloads of up to 443 kg (977 lb) into low Earth orbit, Pegasus first flew in 1990 and remains active as of 2021. The vehicle consists of three solid propellant stages and an optional monopropellant fourth stage. Pegasus is released from its carrier aircraft at approximately 12,000 m (39,000 ft), and its first stage has a wing and a tail to provide lift and attitude control while in the atmosphere. Notably, the first stage does not have a thrust vector control (TVC) system.

More than 1,700 launches have been conducted at the range to study the Earth's atmosphere and the interaction between the atmosphere and the space environment. Areas studied at PFRR include the aurora, plasma physics, the ozone layer, solar proton events, Earth's magnetic field, and ultraviolet radiation. Rockets launched at PFRR have attained an apogee of 930 miles (1,500 km).

The first stage booster consists of a surplus Navy Terrier MK 12 Mod 1 rocket motor with four 0.22 m2 (340 sq in) fin panels arranged in a cruciform configuration. The Terrier rocket booster has a diameter of 460 mm (18 in). The second stage solid rocket is a Thiokol Malemute TU-758 rocket motor, specially designed for high altitude research rocket applications. Apogee is approximately 400 km (220 nmi) for a 230 kg (510 lb) payload or 700 km (380 nmi) for a 41 kg (90 lb) payload. For a payload weight of 200 lb (91 kg), the acceleration during the boost phase is 26 g.
