Washington: NASA is all set to test its low-density supersonic decelerator (LDSD) – a flying saucer designed to check out landing technologies for future Mars missions – over Hawaii.

If weather permits, the LDSD test vehicle will be carried aloft by a large weather balloon at 10 p.m. (Indian standard time) on Tuesday from the US Navy’s Pacific Missile Range Facility in Kauai, Hawaii.

For more than two hours, the balloon will carry the test vehicle to an altitude of 120,000 feet.

The tracking cameras NASA has employed for the test are expected to keep the balloon and test vehicle in their sights for about 30 minutes after launch, the US space agency said in a statement.

After reaching a height of 180,000 feet, a doughnut-shaped airbag will inflate around the saucer for its descent to earth.

The saucer is expected to splash down in the Pacific Ocean about two hours and 15 minutes after launch.

“The test is centred on how our newly-designed supersonic parachute will perform. We think we have a great design ready for the challenge, but the proof is in the pudding and the pudding will be made live for everyone to see,” said Mark Adler, project manager for LDSD at NASA’s Jet Propulsion Laboratory in Pasadena, California.

In order to support a human mission to the Red Planet, NASA needs technologies capable of landing between 20 to 30 metric tonnes on the Martian surface.

The LDSD supports payloads of two to three tonnes, doubling the current capabilities.

During the test flight, viewers will see live, low-resolution images from high over the Pacific Ocean off the west coast of Kauai, Hawaii.

Four cameras aboard the test vehicle will provide the LDSD mission team with different perspectives on the test.

The LDSD mission will test breakthrough technologies that will enable large payloads to be safely landed on the surface of Mars, and also will allow access to more of the planet’s surface by enabling landings at higher-altitude sites. (IANS)

Rocket Lab is Set To Launch 10 NASA CubeSats

They will be placed in RailPODs aboard the Electron rocket that will ferry them to space

In its first mission for NASA, the American aerospace manufacturer Rocket Lab is set to launch 10 small research satellites, or CubeSats, from New Zealand, the US space agency said.

Owing to bad weather, Rocket Lab was forced to postpone the earlier decided launch on December 12.

Rocket Lab is now targeting the ELaNa-19 launch on December 15 with a launch window opening at 11 p.m. EST from the company’s launch complex on the Mahia Peninsula in New Zealand, NASA said in a statement on Friday.

The CubeSats were built by three NASA centres, seven universities, and a middle school under the NASA’s Educational Launch of Nanosatellites, or (ELaNa-19) mission.

ElaNa-19 is NASA’s first to be completely dedicated to launching CubeSats under the agency’s Venture Class Launch Services program for small-satellite launches.

More than 250 students have been involved in the design, development and construction of the CubeSats scheduled to be flown as payloads on Rocket Lab’s Electron rocket.

“The major difference between today’s launch and previous #ELaNa missions is that for the first time, NASA will have a launch completely dedicated to CubeSats rather than having the small satellites ride along with a much larger spacecraft that is the primary mission,” NASA Launch Services Program officials wrote on Twitter on December 12.

The 10 CubeSats are named as CubeSail, CeREs, NMTSat, CHOMPTT, ALBus, STF-1, ISX, RSat, Shields-1 and DaVinci, NASA said.

These are built to standard dimensions of one unit (1U), and can be 1U, 2U, 3U or 6U in size. They generally weigh less than 1.33 kg per U — 6U may be up to 12 kg.

They will be placed in RailPODs aboard the Electron rocket that will ferry them to space.

After the main payload deploys, the CubeSats will separate from their RailPODs. After 45 minutes in orbit, the CubeSat transmitters will turn on and university ground stations will listen for their beacons, determine their small satellites’ functionality and announce operational status.

CubeSat mission durations and orbital life vary but are anticipated to last at least three years. Upon mission completion, the CubeSats fall to Earth, burning up in the atmosphere, NASA noted. (IANS)
