The Nanosatellite Launch Adapter System (NLAS)
was developed to increase access to space while
simplifying the integration process of miniature
satellites, called nanosats or cubesats, onto
launch vehicles. It consists of an adapter, four
dispensers and a sequencer. The adapter is
mounted to the lower surface of the launch
vehicle and the upper deck of the primary
mission spacecraft.

Nanosatellites now have their own mass transit to catch rides to space and perform experiments in microgravity. A new NASA-designed and developed satellite deployer, dubbed the Nano Launch Adapter System (NLAS), is scheduled to demonstrate the capability to launch a flock of satellites into space later this year.

Capable of carrying up to 24 nanosatellite units, or more than 100 pounds of secondary payloads into orbit, the deployer is complete and ready for flight. NLAS is designed to sit beneath a primary spacecraft and connect it to the upper stage of a rocket.

Standing a mere ten inches tall, NLAS is short enough to squeeze various configurations of cubesats, such as 3-unit satellites that measure approximately 14 inches long, 4 inches wide and 4 inches high, or 6-unit satellites that measure approximately 14 inches long, 9 inches wide and 4 inches high.

Engineers expect that several NLAS could be stacked in a launch vehicle, allowing a single launch to bring dozens of small satellites to orbit. Once the primary spacecraft is safely delivered to orbit, NLAS deploys its payloads successively to their destinations, sometimes in a constellation.

"The launch adapter greatly enhances NASA's ability to rapidly deploy small low-cost satellites to space," said David Korsmeyer, director of engineering at NASA Ames Research Center at Moffett Field, Calif. "We expect this will improve NASA's opportunities to fly small satellite missions as secondary payloads and lead to greater opportunities for more complex and efficient spacecraft launches in the future."

This NLAS flight demonstration is expected to show the potential value of multiple, small satellites as tools for a wide array of scientific, commercial, and academic space research. Other goals of the project include reducing the cost and time required to integrate nanosatellites to rockets.

Each time a rocket launches, it must be painstakingly balanced using ballast - which can be sand, water or metal used as a balancing mechanism - to ensure its trajectory is accurate. Nanosatellites and their deployment systems also can act as ballasts during launches.

"Small spacecraft have the advantage of being able to share launches with other spacecraft, reducing the launch cost to the spacecraft developer team. This allows us to launch a number of these smallsats in support of NASA's space technology goals," said Bruce Yost, the program manager for the Small Spacecraft Technology Program at NASA Ames.

NLAS was designed and constructed by a team of experts from the Mission Design Division at Ames, commercial entities, and other government agencies. NASA Ames employees built the NLAS deployer using off-the-shelf components and specially crafted parts designed to standard dimensions for 1-, 3- and 6-unit nanosatellites launched from a variety of rockets, including Falcon 1 and Minotaur 1.

NLAS is jointly funded by the Small Spacecraft Technology Program of the Space Technology Mission Directorate at NASA Headquarters in Washington and NASA Ames.

Comentário: Pois é leitor, trago essa matéria visando dar uma sugestão aos grupos que já desenvolvem cubesats e nanosats no Brasil, INPE, UFSM, IFI, UFRN, USP, entre outros, e empresas como a ARION e AIRVANTIS, que entrem em contato com o IAE e vejam a possibilidade de desenvolvimento de um sistema como esse para ser acoplado ao VLM-1, pois a previsão de seu primeiro voo (voo de qualificação) é 2015, e após o seu voo suborbital do experimento SHEFEX III em 2016, o mesmo estará disponível para atender a demanda brasileira e internacional de micros e nanossatélites, e certamente precisará de um sistema como esse. Ajudem o Brasil a encontrar uma solução o quanto antes para esse problema, antes que sejamos obrigados a adotar uma opção estrangeira.
