SpaceX just notched another milestone on the path to its first-ever crewed launch next week.
Elon Musk’s company is gearing up for the Wednesday (May 27) launch of the Demo-2 mission, which will send NASA astronauts Bob Behnken and Doug Hurley to the International Space Station (ISS) aboard a SpaceX Crew Dragon capsule.
This afternoon (May 22), the company performed a “static fire” test of the Falcon 9 rocket that will launch Demo-2, firing up the booster’s first-stage engines briefly on the pad at NASA’s Kennedy Space Center in Florida.
The static fire occurred just a few hours after NASA, ISS and SpaceX teams wrapped up a critical, two-day flight readiness review (FRR), which declared Demo-2 clear for its planned May 27 liftoff.
There are still a few boxes to check over the next few days, however. On Saturday (May 23), for example, mission teams will run through a “dry dress” exercise, which will simulate many of the activities that NASA and SpaceX will perform in the leadup to launch on Wednesday. Behnken and Hurley will suit up for the dry dress, agency officials said.
And on Monday (May 25) comes the final launch readiness review, which will incorporate analyses of the data from the static fire and the dry dress along with other information, NASA officials said.
Demo-2 is designed to fully validate Crew Dragon and Falcon 9 for crewed flight, clearing the way for operational astronaut-carrying missions. SpaceX holds a contract with NASA’s Commercial Crew Program to conduct six such flights (as does Boeing, which is developing a capsule called CST-100 Starliner).
Crew Dragon has reached the ISS once before, on the uncrewed Demo-1 mission in March 2019. But Demo-2 will be the first orbital human mission to launch from the United States since the final flight of NASA’s space shuttle program in July 2011. Since then, the space agency has relied on Russian Soyuz rockets and spacecraft to get its astronauts to and from the ISS.

If you’re considering a Tempurpedic bed for your next mattress purchase, keep reading for a helpful overview of their product range, including different sleep system features, accessories, price points and where you can purchase their products.
The TEMPUR Material
Tempurpedic beds are reactive and conforming thanks to the popular TEMPUR material that conforms to your shape and alleviates pressure points the when you sit on it or lay down. TEMPUR is patented and used by NASA astronauts as their sleeping surface of choice.
Because dust, dust mites and mold can be a major health hazard, Tempurpedic beds are treated with an anti-allergen that prevents infestation. The mattress fabrics and sprays are also free from formaldehyde and CFC (chloroflourocarbons).
You don’t have to own a complete Tempurpedic bed sleep system to enjoy its helpful TEMPUR material experience. The company also sells pillows, office lumbar cushions and bed accessories like linens and mattress covers.
For the workplace, Tempurpedic sells a wide range of chair covers, lumbar pillows and neck supports designed to relive pressure and provide you with a work environment that supports your back very well.
Meanwhile, the company’s pillow designs include neck pillows, bed pillows, body pillows and travel pillows. All of these products are made using TEMPUR material, which helps you to get a more comfortable night’s sleep and greater support.
Pricing and Costs
Tempurpedic beds range in price from $700 for a basic, small mattress to about $6700 for a full-sized king luxury-model. The beds are somewhat expensive and can often run for much more than the average person is able to part with, but they’re also high-quality and backed by an extensive and comprehensive warranty program.
Financing is also available, direct from the Tempurpedic website (tempurpedic.com) or often through retailers like Sears, Macy’s or Bloomingdale’s. Deals can also be found online, but consumers should be aware of counterfeit models.
Any Tempurpedic bed comes with a 20-year limited warranty. Basically, the company guarantees that for 20 years they will replace or repair any defective mattress that is found to be so because of structural problems or faulty workmanship.
However, the Tempurpedic warranty will not pay for regular wear and tear, nor will it replace or fix any mattresses that have become naturally soft over time. Over the course of many years, the TEMPUR material will become softer.
Finally, the company charges a 50 percent of original cost replacement charge for any mattresses replaced under warranty after 11 years of use. And though the warranty limitations on Tempurpedic Beds may seem steep, the company has a strong level of customer satisfaction and reported customer service.
