Student-built satellite from University at Buffalo to be launched by NASA

The National Aeronautics and Space Administration (NASA) recently made a deal to send into space a satellite that has been designed and built by a group of students from the University at Buffalo. The spacecraft, named Glint Analyzing Data Observation Satellite (GLADOS), was built for two years and is designed to keep track of debris orbit and size circling the Earth.

Project leader John Crassidis, who is also a professor of mechanical and aerospace engineering at UB, will test his theory that sparkles of sunlight reflecting off space junk can be used to determine its mass, size, shape and spin. To prove this project, the GLADOS is equipped with cameras and navigation system. The satellite can also help predict the path of space debris ahead of time, therefore avoiding any collisions.

Composed of 40 engineering students together with John Crassidis, the team got a grant worth $300,000 from the U.S Air Force to fund the GLADOS prototype.

SpaceX successfully launches Falcon 9 to International Space Station

Space Exploration Technologies has another reason to celebrate as the company successfully launched the Falcon 9 rocket containing the Dragon capsule into space. The launch pushed through, despite an anomaly detected on the capsule’s maneuvering thrusters. The issue was resolved after astronauts aboard the outpost used the station's robotic arm to pluck the capsule from orbit at 5:31 a.m. EST, as the ship sailed 250 miles over northern Ukraine. Flight controllers at NASA's Mission Control in Houston then stepped in to drive the capsule to its berthing port on the station's Harmony connecting node.

The Falcon 9 spaceship and its Dragon capsule took off at 10:10 a.m. EST from Cape Canaveral Air Force Station in Florida. The cargo ship -- carrying food, supplies, spare parts and science equipment for the International Space Station -- had astronaut meals and clothing, fresh fruit for the station residents, 640 seeds of a flowering weed for research purposes, mouse stem cells, protein crystals, air-purifying devices, trash bags, computer parts and other necessary gear.

Flight controllers from SpaceX said that they were trying to override the system of the Dragon capsule and activate at least one additional booster required to bring the capsule to its intended orbit. This is the first time SpaceX experienced an anomaly with its Dragon spacecraft while in orbit. The company’s two previous launches to the ISS went through without issues.

The recent flight of the Dragon capsule is a part of SpaceX’s $1.6 billion contract with NASA to resupply the ISS. The space agency is hoping that the collaboration will evolve into using SpaceX to send manned missions into space in the future.

“Using commercial launch providers is more efficient for [NASA], especially after the space shuttles were retired in 2011, and is part of a long-term plan to reduce expenses on low-Earth orbit missions and invest more in deep-space missions,” said Lori Garver, NASA's Associate Administrator.
