Kids are burning each other with boiling water in a deadly “Hot water challenge” YouTube trend

As seen in YouTube and Twitter videos, the “hot water challenge” involves surprising a friend by burning them with boiling water.

Another variation includes challenging someone to drink boiling hot water through a straw or pouring boiling water on themselves.

8-year-old Ki’ari Pope’s cousin dared her to sip boiling water through a straw back in March. She obliged and suffered burns in her mouth and throat, requiring a tracheotomy. In July, she complained that she couldn’t breathe and later died. (Palm Beach Post, GoFundMe)

In addition to Pope, the trend has left several kids with serious injuries.

Jamoneisha Merritt, 11, was at a sleepover Sunday night when her friends poured boiling water over her face as she slept. She suffered extreme injuries and may be left permanently disfigured.

North Carolina 10-year-old Wesley Smith also suffered severe burns after attempting the challenge with his stepbrother, the boy’s mother told WNCN.com, a CBS affiliate.

Parents have begun speaking out about the challenge. Read more (8/10/17)

Solar System: 10 Things to Know This Week

Pioneer Days

Someone’s got to be first. In space, the first explorers beyond Mars were Pioneers 10 and 11, twin robots who charted the course to the cosmos.

1-Before Voyager

Voyager, with its outer solar system tour and interstellar observations, is often credited as the greatest robotic space mission. But today we remember the plucky Pioneers, the spacecraft that proved Voyager’s epic mission was possible.

2-Where No One Had Gone Before

Forty-five years ago this week, scientists still weren’t sure how hard it would be to navigate the main asteroid belt, a massive field of rocky debris between Mars and Jupiter. Pioneer 10 helped them work that out, emerging from first the first six-month crossing in February 1973. Pioneer 10 logged a few meteoroid hits (fewer than expected) and taught engineers new tricks for navigating farther and farther beyond Earth.

3-Trailblazer No. 2

Pioneer 11 was a backup spacecraft launched in 1973 after Pioneer 10 cleared the asteroid belt. The new mission provided a second close look at Jupiter, the first close-up views of Saturn and also gave Voyager engineers plotting an epic multi-planet tour of the outer planets a chance to practice the art of interplanetary navigation.

4-First to Jupiter

Three-hundred and sixty-three years after humankind first looked at Jupiter through a telescope, Pioneer 10 became the first human-made visitor to the Jovian system in December 1973. The spacecraft spacecraft snapped about 300 photos during a flyby that brought it within 81,000 miles (about 130,000 kilometers) of the giant planet’s cloud tops.

5-Pioneer Family

Pioneer began as a Moon program in the 1950s and evolved into increasingly more complicated spacecraft, including a Pioneer Venus mission that delivered a series of probes to explore deep into the mysterious toxic clouds of Venus. A family portrait (above) showing (from left to right) Pioneers 6-9, 10 and 11 and the Pioneer Venus Orbiter and Multiprobe series. Image date: March 11, 1982. 

6-A Pioneer and a Pioneer

Classic rock has Van Halen, we have Van Allen. With credits from Explorer 1 to Pioneer 11, James Van Allen was a rock star in the emerging world of planetary exploration. Van Allen (1914-2006) is credited with the first scientific discovery in outer space and was a fixture in the Pioneer program. Van Allen was a key part of the team from the early attempts to explore the Moon (he’s pictured here with Pioneer 4) to the more evolved science platforms aboard Pioneers 10 and 11.

7-The Farthest…For a While

For more than 25 years, Pioneer 10 was the most distant human-made object, breaking records by crossing the asteroid belt, the orbit of Jupiter and eventually even the orbit of Pluto. Voyager 1, moving even faster, claimed the most distant title in February 1998 and still holds that crown.

8-Last Contact

We last heard from Pioneer 10 on Jan. 23, 2003. Engineers felt its power source was depleted and no further contact should be expected. We tried again in 2006, but had no luck. The last transmission from Pioneer 11 was received in September 1995. Both missions were planned to last about two years.

9-Galactic Ghost Ships

Pioneers 10 and 11 are two of five spacecraft with sufficient velocity to escape our solar system and travel into interstellar space. The other three—Voyagers 1 and 2 and New Horizons—are still actively talking to Earth. The twin Pioneers are now silent. Pioneer 10 is heading generally for the red star Aldebaran, which forms the eye of Taurus (The Bull). It will take Pioneer over 2 million years to reach it. Pioneer 11 is headed toward the constellation of Aquila (The Eagle) and will pass nearby in about 4 million years.

10-The Original Message to the Cosmos

Years before Voyager’s famed Golden Record, Pioneers 10 and 11 carried the original message from Earth to the cosmos. Like Voyager’s record, the Pioneer plaque was the brainchild of Carl Sagan who wanted any alien civilization who might encounter the craft to know who made it and how to contact them. The plaques give our location in the galaxy and depicts a man and woman drawn in relation to the spacecraft.

Webb 101: 10 Facts about the James Webb Space Telescope

Did you know…?

1. Our upcoming James Webb Space Telescope will act like a powerful time machine – because it will capture light that’s been traveling across space for as long as 13.5 billion years, when the first stars and galaxies were formed out of the darkness of the early universe.

2. Webb will be able to see infrared light. This is light that is just outside the visible spectrum, and just outside of what we can see with our human eyes.

3. Webb’s unprecedented sensitivity to infrared light will help astronomers to compare the faintest, earliest galaxies to today’s grand spirals and ellipticals, helping us to understand how galaxies assemble over billions of years.

4. Webb will be able to see right through and into massive clouds of dust that are opaque to visible-light observatories like the Hubble Space Telescope. Inside those clouds are where stars and planetary systems are born.

5. In addition to seeing things inside our own solar system, Webb will tell us more about the atmospheres of planets orbiting other stars, and perhaps even find the building blocks of life elsewhere in the universe.

6. Webb will orbit the Sun a million miles away from Earth, at the place called the second Lagrange point. (L2 is four times further away than the moon!)

7. To preserve Webb’s heat sensitive vision, it has a ‘sunshield’ that’s the size of a tennis court; it gives the telescope the equivalent of SPF protection of 1 million! The sunshield also reduces the temperature between the hot and cold side of the spacecraft by almost 600 degrees Fahrenheit.

8.  Webb’s 18-segment primary mirror is over 6 times bigger in area than Hubble’s and will be ~100x more powerful. (How big is it? 6.5 meters in diameter.)

9.  Webb’s 18 primary mirror segments can each be individually adjusted to work as one massive mirror. They’re covered with a golf ball’s worth of gold, which optimizes them for reflecting infrared light (the coating is so thin that a human hair is 1,000 times thicker!).

10. Webb will be so sensitive, it could detect the heat signature of a bumblebee at the distance of the moon, and can see details the size of a US penny at the distance of about 40 km.

BONUS!  Over 1,200 scientists, engineers and technicians from 14 countries (and more than 27 U.S. states) have taken part in designing and building Webb. The entire project is a joint mission between NASA and the European and Canadian Space Agencies. The telescope part of the observatory was assembled in the world’s largest cleanroom at our Goddard Space Flight Center in Maryland.

Webb is currently being tested at our Johnson Space Flight Center in Houston, TX.

Afterwards, the telescope will travel to Northrop Grumman to be mated with the spacecraft and undergo final testing. Once complete, Webb will be packed up and be transported via boat to its launch site in French Guiana, where a European Space Agency Ariane 5 rocket will take it into space.

Launching the Future of Space Communications

Our newest communications satellite, named the Tracking and Data Relay Satellite-M or TDRS-M, launches Aug. 18 aboard an Atlas V rocket from our Kennedy Space Center in Florida. It will be the 13th TDRS satellite and will replenish the fleet of satellites supporting the Space Network, which provides nearly continuous global communications services to more than 40 of our missions.

Communicating from space wasn’t always so easy. During our third attempt to land on the moon in 1970, the Apollo 13 crew had to abort their mission when the spacecraft’s oxygen tank suddenly exploded and destroyed much of the essential equipment onboard. Made famous in the movie ‘Apollo 13’ by Ron Howard and starring Tom Hanks, our NASA engineers on the ground talked to the crew and fixed the issue. Back in 1970 our ground crew could only communicate with their ground teams for 15 percent of their orbit – adding yet another challenge to the crew. Thankfully, our Apollo 13 astronauts survived and safely returned to Earth. 

Now, our astronauts don’t have to worry about being disconnected from their teams! With the creation of the TDRS program in 1973, space communications coverage increased rapidly from 15 percent coverage to 85 percent coverage. And as we’ve continued to add TDRS spacecraft, coverage zoomed to over 98 percent!

TDRS is a fleet of satellites that beam data from low-Earth-orbiting space missions to scientists on the ground. These data range from cool galaxy images from the Hubble Space Telescope to high-def videos from astronauts on the International Space Station! TDRS is operated by our Space Network, and it is thanks to these hardworking engineers and scientists that we can continuously advance our knowledge about the universe!  

What’s up next in space comm? Only the coolest stuff ever! LASER BEAMS. Our scientists are creating ways to communicate space data from missions through lasers, which have the ability to transfer more data per minute than typical radio-frequency systems. Both radio-frequency and laser comm systems send data at the speed of light, but with laser comm’s ability to send more data at a time through infrared waves, we can receive more information and further our knowledge of space.

How are we initiating laser comm? Our Laser Communications Relay Demonstration is launching in 2019! We’re only two short years away from beaming space data through lasers! This laser communications demo is the next step to strengthen this technology, which uses less power and takes up less space on a spacecraft, leaving more power and room for science instruments.
