Scientists from several organisations in the US, including NASA, are planning to use remote-operated submarines to hunt for the remains of an outer space object — believed to be a meteorite — that splashed down into the Pacific Ocean on March 7, the media reported.

The Nautilus research ship of the non-profit group Ocean Exploration Trust (OET) will aid in the scavenger hunt, Digitaltrends.com reported on Sunday.

Joined by scientists from NASA, the University of Washington and the Olympic Coast National Marine Sanctuary, the Nautilus will use remote-operated submarines to survey the area and collect any fragments they find, it added.

When the outer space object entered the Pacific Ocean, a bright flash lit up the sky and a tremendous boom rattled the residents of Ocean Shores, Washington.

They initially thought it was a spaceship, but from analysis of radar signals, NASA’s cosmic dust sample curator Marc Fries concluded it was a meteorite about the size of a golf cart.

Scientists believe that about two tonnes of fragments are up for grabs. Some of these fragments could be as large as a brick and they could be scattered over a half-mile of the sea floor.

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)
