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)

Below you will find details of some of the very best things to do in Hawaii, helping to make your vacation one to remember:

Enjoy a Spot of Snorkelling

Why not dive into the blue waters and enjoy a spot of snorkelling? The seas in this part of the world are home to some turtles, beautiful fish and some incredible sights. Book a Turtle Canyon Snorkel Cruise, and head off on your tour which comes complete with snorkelling equipment that is suitable for anyone to use. If you’ve never snorkelled before, do not worry, the helpful and friendly instructors will assist you so you can dive into the water with ease.

As part of the cruise, you will be offered a couple of alcoholic drinks and unlimited alcohol-free drinks to enjoy as you make your way to Waikiki and Diamond head on a 16-foot catamaran, where you can take as many photographs as you wish.  Departing from hotels in Waikiki or the Kewalo Basin Harbour, this snorkelling tour should not be missed!

Visit Waikiki Beach

Most people go on vacation to Hawaii so they can enjoy the beautiful beaches and the stunning sunshine.  While you’re visiting this part of the world why not take a trip to Waikiki Beach and relax in the sun or under a palm tree? Listen as the clear blue waters brush up against the shore, and watch as boats, canoes, and divers enjoy their time on and in the water.

If you would like to avoid the beach when it’s busy, you may want to think about visiting early in the morning or as the sun is about to go down. Alternatively, you may also want to visit during the cooler months as there are fewer people on the beach then. Whenever you do decide to visit, you can be sure that you’ll have an amazing time on a beach that is known for its beauty and tropical feel.

Go Whale Spotting

We humans are not the only ones who enjoy the waters off the coast of Hawaii, whales love it too, and they can be spotted off the coast of Maui. Why not take the opportunity to hop on board a Maui Whale Watch Cruise and spend two whole hours spotting whales? Not only are you practically guaranteed to spot some of these magnificent mammals, but you will also get the chance to see them via an underwater webcam and a hydrophone, which is a type of listening device that picks up underwater sounds.

Make sure you take a camera with you so you can get snap-happy when you spot a whale or two. The tour operates from December to May when the whales venture into the waters to breed, which is why you’re almost guaranteed to see them. With many different departure times and setting off from Lahaina, whale spotting will prove to be an unforgettable part of your vacation.

Take a trip to a Coconut Farm

Punakea Palms Coconut Farm is the ideal destination if you want to do something a little different while you’re in Hawaii. Walk around the farm and learn about how it works, how to get into a coconut, and enjoy its bounty. Understand how to cultivate coconuts and learn why they are so important to the local area. Located just outside of Lahaina, the coconut farm also gives you the chance to taste some very fresh coconuts. You will have to book a place on a 2.5-hour tour around the farm, but it is worth it as it’s a lot of fun.

Visit Princeville Botanical Gardens

If you have decided to spend a little time away from the beach and you want to visit somewhere peaceful Princeville Botanical Gardens is the right place for you. Owned and operated by the Robertson family who works hard to create a botanical paradise, the gardens are really beautiful. You will need to make a reservation before you can visit the gardens, but once you get here you’ll enjoy the breathtaking landscape and native Hawaiian plants.

Monsoon, Garden Lovers
Hawaii has some great gardens as well.

While you’re walking around the lush gardens you may notice that honey and fruit are grown in the area, and you’ll get the chance to sample some. Chocolate lovers will also enjoy tasting some locally produced chocolate that tastes divine. Open for tours on Mondays and Tuesdays, Thursdays and Fridays, the Princeville Botanical Gardens need to be seen to be believed.

There are many different activities taking place every day in Hawaii, but the above 5 activities are some of the very best. If you’ve had enough of lounging on the beach for now, why not take a trip to a coconut farm, spot some whales as you cruise on a catamaran, and make your way around some magnificent botanical gardens. Finish off with a spot of snorkelling before you head to Waikiki Beach and relax in the sunshine as you feel the sand in between your toes, and feel a fresh breeze hit you as the sun beats down.
