Rockets, Racecars, and the Physics of Going Fast

When our Space Launch System (SLS) rocket launches the Artemis missions to the Moon, it can have a top speed of more than six miles per second. Rockets and racecars are designed with speed in mind to accomplish their missions—but there’s more to speed than just engines and fuel. Learn more about the physics of going fast:

Take a look under the hood, so to speak, of our SLS mega Moon rocket and you’ll find that each of its four RS-25 engines have high-pressure turbopumps that generate a combined 94,400 horsepower per engine. All that horsepower creates more than 2 million pounds of thrust to help launch our four Artemis astronauts inside the Orion spacecraft beyond Earth orbit and onward to the Moon. How does that horsepower compare to a racecar? World champion racecars can generate more than 1,000 horsepower as they speed around the track.

As these vehicles start their engines, a series of special machinery is moving and grooving inside those engines. Turbo engines in racecars work at up to 15,000 rotations per minute, aka rpm. The turbopumps on the RS-25 engines rotate at a staggering 37,000 rpm. SLS’s RS-25 engines will burn for approximately eight minutes, while racecar engines generally run for 1 ½-3 hours during a race.

To use that power effectively, both rockets and racecars are designed to slice through the air as efficiently as possible.

While rockets want to eliminate as much drag as possible, racecars carefully use the air they’re slicing through to keep them pinned to the track and speed around corners faster. This phenomenon is called downforce.

Steering these mighty machines is a delicate process that involves complex mechanics.

Most racecars use a rack-and-pinion system to convert the turn of a steering wheel to precisely point the front tires in the right direction. While SLS doesn’t have a steering wheel, its powerful engines and solid rocket boosters do have nozzles that gimbal, or move, to better direct the force of the thrust during launch and flight.

Racecar drivers and astronauts are laser focused, keeping their sights set on the destination. Pit crews and launch control teams both analyze data from numerous sensors and computers to guide them to the finish line. In the case of our mighty SLS rocket, its 212-foot-tall core stage has nearly 1,000 sensors to help fly, track, and guide the rocket on the right trajectory and at the right speed. That same data is relayed to launch teams on the ground in real time. Like SLS, world-champion racecars use hundreds of sensors to help drivers and teams manage the race and perform at peak levels.

Knowing how to best use, manage, and battle the physics of going fast, is critical in that final lap. You can learn more about rockets and racecars here.

NASA Inspires Your Crafty Creations for World Embroidery Day

It’s amazing what you can do with a little needle and thread! For #WorldEmbroideryDay, we asked what NASA imagery inspired you. You responded with a variety of embroidered creations, highlighting our different areas of study.

Here’s what we found:

Webb’s Carina Nebula

Wendy Edwards, a project coordinator with Earth Science Data Systems at NASA, first learned cross stitch in middle school where she had to pick rotating electives and cross stitch/embroidery was one of the options.  “When I look up to the stars and think about how incredibly, incomprehensibly big it is out there in the universe, I’m reminded that the universe isn’t ‘out there’ at all. We’re in it,” she said. Her latest piece focused on Webb’s image release of the Carina Nebula. The image showcased the telescope’s ability to peer through cosmic dust, shedding new light on how stars form.

Danielle Currie is an environmental professional who resides in New Brunswick, Canada. She began embroidering at the beginning of the Covid-19 pandemic as a hobby to take her mind off the stress of the unknown. Danielle’s piece is titled “46.69, 50.43,” named after the coordinates of the area of the northern Caspian Sea captured by LandSat8 in 2019.

Two Hubble Images of the Pillars of Creation, 1995 and 2015

Melissa Cole is an award-winning fiber artist from Philadelphia, PA, USA, inspired by the beauty and vastness of the universe. They began creating their own cross stitch patterns at 14, while living with their grandparents in rural Michigan, using colored pencils and graph paper.  The Pillars of Creation (Eagle Nebula, M16), released by the Hubble Telescope in 1995 when Melissa was just 11 years old, captured the imagination of a young person in a rural, religious setting, with limited access to science education.

Lauren Wright Vartanian of Guelph, Ontario Canada considers herself a huge space nerd. She’s a multidisciplinary artist who took up hand sewing after the birth of her daughter. She’s currently working on the illustrations for a science themed alphabet book, made entirely out of textile art. It is being published by Firefly Books and comes out in the fall of 2024. Lauren said she was enamored by the original Pillars image released by Hubble in 1995. When Hubble released a higher resolution capture in 2015, she fell in love even further! This is her tribute to those well-known images.

James Webb Telescope Captures Pillars of Creation

Darci Lenker of Norman, Oklahoma started embroidery in college more than 20 years ago, but mainly only used it as an embellishment for her other fiber works. In 2015, she started a daily embroidery project where she planned to do one one-inch circle of embroidery every day for a year.  She did a collection of miniature thread painted galaxies and nebulas for Science Museum Oklahoma in 2019. Lenker said she had previously embroidered the Hubble Telescope’s image of Pillars of Creation and was excited to see the new Webb Telescope image of the same thing. Lenker could not wait to stitch the same piece with bolder, more vivid colors.

In this piece, Lenker became inspired by the Milky Way Galaxy, which is organized into spiral arms of giant stars that illuminate interstellar gas and dust. The Sun is in a finger called the Orion Spur.

The Cosmic Microwave Background

Jessica Campbell obtained her PhD in astrophysics from the University of Toronto studying interstellar dust and magnetic fields in the Milky Way Galaxy. Jessica promptly taught herself how to cross-stitch in March 2020 and has since enjoyed turning astronomical observations into realistic cross-stitches. Her piece was inspired by the cosmic microwave background, which displays the oldest light in the universe.

Katy Mersmann is a social media specialist at NASA’s Goddard Space Flight Center in Greenbelt, Md. She started embroidering when she was in graduate school. Many of her pieces are inspired by her work as a communicator. With climate data in particular, she was inspired by the researchers who are doing the work to understand how the planet is changing. The GISTEMP piece above is based on a data visualization of 2020 global temperature anomalies, still currently tied for the warmest year on record.

In addition to embroidery, NASA continues to inspire art in all forms. Check out other creative takes with Landsat Crafts and the James Webb Space telescope public art gallery.

Guy Bluford Changed the Course of Space History

On Aug. 30, 1983, Guion Bluford, better known as Guy, became the first African American to fly to space. An accomplished jet pilot and aerospace engineer, Bluford became part of NASA’s 1978 astronaut class that included the first African American, the first Asian American, and the first women astronauts.

He and the other crew members of mission STS-8 were aboard the orbiter Challenger as it lifted off from Kennedy Space Center in Florida; it was the first nighttime launch and landing of the Space Shuttle program. While aboard, he and the other crew members deployed the Indian National Satellite (INSAT-1B), operated a Canadian-built robot arm, conducted experiments with live cell samples, and participated in studies measuring the effects of spaceflight on humans.

Guy Bluford chased his childhood dream of becoming an aerospace engineer, and in doing so, changed history and encouraged other Black astronauts to follow in his footsteps.

True story. My author/journalist/landlady took a trip to the States, met up with my college student friend to be shown the US college student life, and then pushed her into putting her credit card details into her Uber app.

Then over the course of the remainder of her trip she used my friend’s card to pay for her Uber trips until the money ran out.

The kicker to this story is that she wants 10k in upfront heating gas costs for the year because of “the war”.

Why are rich people so bad at money?
