Control Software Navigates Lunar CubeSats

GNAT Programming Studio and GNAT Pro Compiler Software AdaCore New York, NY 866-787-4232 www.adacore.com Vermont Technical College’s Lunar CubeSat, measuring only 10 × 10 × 10 cm and weighing 1.1 kg, was launched into a 500-km earth orbit. The small satellite will remain in orbit for about three years to test the systems that will be used for an eventual lunar mission. The CubeSat project is part of NASA’s ELaNa (Educational Launch of Nano-satellites) IV program. The CubeSat’s navigation and control software was developed in SPARK/Ada using AdaCore’s GNAT Programming Studio (GPS) IDE and GNAT Pro compiler; the SPARK toolset from Altran, headquartered in Neuilly-sur-Seine, France, proved the absence of runtime errors.

Lunar Simulants Provide Critical Tests for Moon Missions

NU-LHT lunar simulant Zybek Advanced Products (ZAP) Boulder, CO 888-469-0110 www.zybekap.com Lunar simulants are a critical aspect of the return to the Moon and a planned lunar outpost. All mechanical equipment, chemical processes, and human health studies will be tested extensively with simulants prior to deployment. Zybek Advanced Products’ NU-LHT (NASA-USGS — Lunar Highlands Type) simulant is used by NASA to represent the lunar highlands area, and contains a complex mixture of glass, agglutinate, jagged particulates, synthetic minerals, and natural minerals from select terrestrial sources. While glass and crystal structures exist terrestrially, the agglutinate structure is not available on Earth.

Thrusters Support Communications Satellite Launch

Monopropellant (hydrazine) thrustersAerojet RocketdyneSacramento, CA 916-355-4000 www.rocket.com Aerojet Rocketdyne, a GenCorp company, played a vital role in placing the second of three next-generation Tracking and Data Relay Satellites (TDRS-L) into orbit for NASA. In the second stage of launch, a single RL10A-4-2 engine ignited to place the TDRS-L into orbit, helped by 12 Aerojet Rocketdyne monopropellant (hydrazine) thrusters in four modules on the United Launch Alliance Atlas V Centaur upper stage, providing roll, pitch, and yaw control, as well as propellant settling burns during ascent. The RL10A-4-2 engine delivers 22,300 pounds of thrust to power the Atlas V upper-stage, using cryogenic liquid hydrogen and liquid oxygen propellants during its operation. ARDe, a New Jersey-based subsidiary of Aerojet Rocketdyne, provides the pressure vessels on the first and second stages of the launch vehicle. TDRS-L will use a single R-4D 100-lbf thruster for orbit insertion.

Water Impact Simulation Ensures Safer Landing for NASA Astronauts

The water landing of a craft like the Orion Crew Module is a very complex and changeable event, subject to the dynamics of the vehicle’s structure and sub-structures, such as its heat shield and atmospheric and water conditions. To maintain the spacecraft’s structural integrity and increase safety of the crew, a clearer understanding of the dynamic loads generated during water impact was required.
