Lower Decks' Tribute to Deep Space Nine Is Perfect Beyond Pastiche

This week’s Star Trek: Lower Decks opens with a gag about the slow, majestic grandeur of the Deep Space Nine title theme. And if that was all Lower Decks had to offer for an episode set on the iconic show’s titular space station, that might be fine, if disappointing—and in line with the first half of this season.…

Peloton fitness gear will soon be available at Dick's Sporting Goods

It’s been a turbulent year for Peloton to say the least. Part of the company’s plan to right the ship is to offer its connected fitness gear through third-party retailers. It started selling equipment through Amazon in August and now Peloton has an exclusive deal with a brick-and-mortar retailer. So, you soon may be able to walk into a Dick’s Sporting Goods location and pick up a Bike, Tread or Guide after seeing it in person. It seems Dick’s won’t carry Peloton’s new rowing machine for now, though.

The fitness gear and some accessories will be available in more than 100 Dick’s retail locations in the US (there are more than 700 in total, as CNBC points out) and through the company’s online sales channels in the coming weeks. The physical locations will have Peloton-branded fitness shops where the gear will be displayed and Dick’s employees will be trained to help shoppers with the equipment.

Peloton says Dick’s will be the only retailer that offers this selection of its hardware outside of its own online and physical stores. However, Peloton plans to start closing at least some of its showrooms next year.

At least to begin with, Peloton will handle delivery and setup if you order a Bike or Tread from Dick’s. That may not last for long as the company announced plans in August to lay off members of its distribution team and rely entirely on third-party companies for deliveries and setting up equipment.

The Dick’s partnership is part of Peloton’s strategy to accelerate growth and increase revenue in the wake of dismal earnings results. Aligned with that blueprint, Peloton this month expanded Bike rentals to 48 states.

James Webb and Hubble telescope images capture DART asteroid collision

NASA made history this week after an attempt to slam its DART (Double Asteroid Redirection Test) spacecraft into an asteroid nearly 7 million miles away proved successful. While NASA shared some close-up images of the impact, it observed the planetary defense test from afar as well, thanks to the help of the James Webb and Hubble space telescopes. On the surface, the images aren’t exactly the most striking things we’ve seen from either telescope, but they could help reveal a lot of valuable information.

This was the first time that Hubble and JSWT have observed the same celestial target simultaneously. While that was a milestone for the telescopes in itself, NASA suggests the data they captured will help researchers learn more about the history and makeup of the solar system. They’ll be able to use the information to learn about the surface of Dimorphos (the asteroid in question), how much material was ejected after DART crashed into it and how fast that material was traveling.

JWST and Hubble picked up different wavelengths of light (infrared and visible, respectively). NASA says that being able to observe data from multiple wavelengths will help scientists figure out if big chunks of material left Dimorphos’ surface or if it was mostly fine dust. This is an important aspect of the test, as the data can help researchers figure out if crashing spacecraft into an asteroid can change its orbit. The ultimate aim is to develop a system that can divert incoming asteroids away from Earth.

NASA says that JWST picked up images of “a tight, compact core, with plumes of material appearing as wisps streaming away from the center of where the impact took place.” JWST, which captured 10 images over five hours, will continue to collect spectroscopic data from the asteroid system in the coming months to help researchers better understand the chemical composition of Dimorphos. NASA shared a timelapse GIF of the images that JWST captured. 

This animation, a timelapse of images from NASA’s James Webb Space Telescope, covers the time spanning just before impact at 7:14 p.m. EDT, Sept. 26, through 5 hours post-impact. Plumes of material from a compact core appear as wisps streaming away from where the impact took place. An area of rapid, extreme brightening is also visible in the animation.

At around 14,000 MPH, Dimorphos was traveling at a speed over three times faster than JWST was originally designed to track. However, the telescope’s flight operations, planning and science teams were able to develop a way to capture the impact.

As for Hubble, the 32-year-old telescope’s Wide Field Camera 3 captured its own images of the collision. “Ejecta from the impact appear as rays stretching out from the body of the asteroid,” according to NASA. The agency noted that some of the rays appear curved, and astronomers will have to examine the data to gain a better understanding of what that may mean.

These images from NASA’s Hubble Space Telescope, taken (left to right) 22 minutes, 5 hours, and 8.2 hours after NASA’s Double Asteroid Redirection Test (DART) intentionally impacted Dimorphos, show expanding plumes of ejecta from the asteroid’s body. The Hubble images show ejecta from the impact that appear as rays stretching out from the body of the asteroid. The bolder, fanned-out spike of ejecta to the left of the asteroid is in the general direction from which DART approached.

According to their initial findings, though, the brightness of the asteroid system increased threefold after impact. That level of brightness stayed the same for at least eight hours. Hubble captured 45 images immediately before and after DART’s impact. It will observe the asteroid system 10 additional times over the next few weeks.

It took 10 months for DART, which is about the size of a vending machine, to reach Dimorphos. The football stadium-sized asteroid was around 6.8 million miles away from Earth when DART rammed into it. Pulling off an experiment like that is no mean feat. The learnings scientists gain from the test may prove invaluable.
