Sounding Rocket Flight Ends Prematurely
July 1, 2014
WALLOPS ISLAND, Va.—The flight of a Terrier-Improved Malemute sounding rocket from NASA’s Wallops Flight Facility ended prematurely today at 4:36 a.m. EDT about 19 seconds after its launch.
Range controllers detected a flight anomaly with the second stage Improved Malemute motor; the vehicle flew to an altitude of 27,000 feet and impacted about one nautical mile downrange.
There were no injuries or property damage as the vehicle landed in the established hazard zone in the Atlantic Ocean, which was cleared prior to launch.
A NASA team will investigate the cause of the flight anomaly and more information will be released as it becomes available
UPDATE: It appears as if we have had a failure of our Terrier-Improved Malemute suborbital sounding rocket after liftoff this morning. We will post more information as it becomes available.
UPDATE: The SubTec-6 launch scheduled for Tuesday, July 1, has scrubbed due to boats in the hazard area. The next launch attempt is Wednesday, July 2, with a launch window from 4 to 5 a.m.
UPDATE: The SubTec-6 launch scheduled for Monday, June 30, has scrubbed due to boats in the hazard area and poor science conditions at Wallops. The next launch attempt is Tuesday, July 1, with a launch window from 4 to 5 a.m.
UPDATE: The SubTec-6 launch scheduled for Sunday, June 29, has scrubbed due to boats in the hazard area. The next launch attempt is Monday, June 30, with a launch window from 4 to 5 a.m.
UPDATE: The SubTec-6 launch scheduled for Saturday, June 28, has scrubbed due to poor science conditions, wind, and boats in the hazard area. The next launch attempt is Sunday, June 29, with a launch window from 4 to 5 a.m.
06.24.14 - NASA will test several new suborbital rocket technologies with the launch of a Terrier-Improved Malemute sounding rocket between 4 and 5 a.m., June 28, from the Wallops Flight Facility in Virginia. The backup launch days are June 29 through July 2.
These technologies will include a deployment system for forming vapor clouds used to track the winds in space for studies of the ionosphere; a miniature deployment actuator for small spacecraft called cubesats; a low-cost attitude solution system; and improvements in telemetry and flight recorders to increase the rates for data collected and transferred during flight.
The sub-payload deployment method being tested on this flight uses small rocket motors like those used in model rockets to eject the sub-payloads from the main payload. During the test, two sub-payloads with mixtures of mainly barium will be deployed from the sounding rocket. In addition to the barium, the two sub-payloads contain small amounts of the natural earth metals lithium and strontium.
By combining the metals and burning them rapidly, the mixture will produce enough heat and vaporize the mixture to form clouds that will help to measure the wind in the transition region between the Earth’s atmosphere and space. The vapor releases occur at approximately 220 seconds after vehicle lift-off between 68 and 86 miles above the Earth.
The byproducts from burning these metals do not pose a risk to health or the environment given their release in space. The amount of barium, strontium and lithium used in the test is much smaller than that used in a typical municipal 4th of July fireworks display, for example. The colors in these displays are the result of rapidly burning small amounts of these earth metals. For instance, barium generally produces a cloud with a mixture of blue-green while strontium and lithium produce blues and reds.
The clouds, which help researchers measure the velocity and direction of the wind in the space, may be seen by residents in the mid-Atlantic region.
The NASA Visitor Center at Wallops will be open at 3:30 a.m. for viewing the launch.

RockOn Sounding Rocket Launches Successfully
June 26, 2014
UPDATE: The RockOn Terrier-Improved Orion sounding rocket containing multiple student-built experiments launched successfully at 7:21 a.m. EDT on June 26, 2014 from NASA’s Wallops Flight Facility in Virginia. The payload was recovered and has been returned to Wallops. The students will conduct their preliminary analysis on their experiments later this afternoon. According to the preliminary information, the payload flew to an altitude of 73.3 miles and landed via parachute 43.9 miles from Wallops Island in the Atlantic Ocean 12.16 minutes after launch.
The next launch from Wallops will be a Terrier-Improved Malemute sounding rocket carrying the SubTec-6 payload between 4 and 5 a.m., Saturday, June 28. Backup launch days run through July 2.

Students and educators from across the United States will become "rocket scientists" during two workshops at NASA’s Wallops Flight Facility in Virginia this month.
The seventh annual RockOn! workshop, conducted in partnership with the Colorado and Virginia Space Grant Consortia, will provide 61 community college and university students and instructors the opportunity to learn how to build a scientific payload for a suborbital rocket flight. This workshop is June 21–26.
During the fourth annual Wallops Rocket Academy for Teachers (WRATs), June 23–27, 20 high school educators will receive instruction on the physics and math behind rocket flight and how to incorporate what they learn into classroom curriculum.
"These two workshops provide students and faculty the opportunity to expand their education," said Joyce Winterton, Wallops senior advisor for education and leadership development. "It's a hands-on learning experience that will prepare participating students for their future careers in science, technology, engineering, and math (STEM) and provide the educators with information to expand opportunities for students in the classroom."
During RockOn!, participants will learn the basics of experiment design including programming and electronics. The students will construct experiments to measure acceleration, spin rate, radiation, humidity, pressure and temperature during a rocket flight.
Their experiments, built in only three days, will then be incorporated into a rocket payload for launch on a Terrier-Improved Orion suborbital sounding rocket at 5:30 a.m. EDT Thursday, June 26. After flying to nearly 70 miles in altitude, the payload carrying the experiments will land in the Atlantic Ocean where it will be recovered. The participants are expected to have their experiments in hand later in the day to begin data analysis.
In addition to the RockOn! experiments, a group of more complex experiments from the RockSat-C program also will be flying on the sounding rocket. These experiments are developed by students, many of whom have participated in a previous RockOn! workshop, from Mitchell Community College, Statesville, North Carolina; West Virginia University, Morgantown; Carthage College, Kenosha, Wisconsin; Temple University, Philadelphia; and Howard University in Washington.
About 50 students and instructors participating in RockSat-C will come to Wallops on Friday, June 20 to begin their final experiment integration and to witness the launch.
"The RockOn! and RockSat-C programs are part of an effort to expand students' skills in developing experiments for spaceflight," said Chris Koehler, director of the Colorado Space Grant Consortium." These two programs, coupled with RockSat-X, which requires an even more advanced skillset, will help prepare these students for future careers in the aerospace industry and at NASA."
In addition, more than 100 small cubes carrying experiments developed by pre-college students will launch with RockSat-C as part of the Cubes in Space program. Experiments vary from measuring changes in the electromagnetic field as the experiment moves through the ionosphere to determine whether the nano-computers would survive spaceflight, to observing the changes to the properties of a marshmallow as a result of the intense g-force of the launch. Cubes in Space is a partnership between Rubik Learning Initiative, idoodlesoftware inc. and the Colorado Space Grant Consortium.
During WRATS, participants will receive instruction from Wallops engineers on the basics of rocketry, including Newton’s Laws, electronic fundamentals, drag and propulsion. This instruction will be applied to hands-on learning activities, including building and launching model rockets. The WRATS participants also will attend the RockOn! launch on June 26.
"Rocket Week is designed to inspire and increase the participants' interest in STEM and prepare the students for their careers," said Phil Eberspeaker, chief of the NASA Sounding Rocket Programs Office at Wallops. "Through these programs, the participants will experience what it takes to be a rocket scientist."
The RockOn! and WRATS workshops are supported by the NASA Sounding Rocket Program. RockOn! also is supported by NASA's Office of Education and the National Space Grant College and Fellowship Program.
